Microsoft has produced it as easy as they will for you to by providing away quite a great Visual Studio based development system free: Visual 2010 Express Edition. Really. It s actually free. No 2010 Express can be a free version of Visual Studio 2010, Microsoft s premier development environment. In this lesson, you learn how it is, learn how to get it, and learn how to get started by writing a software program.
No textbook is needed. Later lessons feature downloadable example programs to assist you learn. When you install 2010 Express, the primary screen the truth is will look like this:
Because Express is often a version of Visual Studio, virtually any book about Visual Studio should also apply to Express to varying degrees, so occurs Visual Studio books for those who have them and when they connect with Visual Basic.
All you want to do is download Visual Basic Express from Microsoft and begin learning.
This course is a living document. I intend to update it and extend it frequently to help keep it current and combine content. If you've any great tips on something that must be changed or added, told me about it.
We ll take it slow on this first lesson, but we'll write a course - by far the most basic program which it s possible to publish. Since we re just getting going, I don t desire to leave anybody behind. In later lessons, the pace will get quite a bit.
The excellent news is the fact Visual 2010 Express Edition is often a great learning tool although you may buy Visual Studio eventually. It s depending on exactly the same Framework 4 that this much, far more expensive versions are. If you re into version numbering, that is version 10.0 of Visual Basic.
I perform lot of development using VB Express and I can provide my personal assurance who's s a primary class development system with many of the popular features of Visual Studio versions that Microsoft will cost you thousands of US dollars. My advice: Take advantage of Microsoft and employ 2010 Express. Buy the more costly Visual Studio 2010 version only once you absolutely ought to.
About Visual Basic seemingly independent of Microsoft so that as far as I m concerned, Bill has enough money.
As a beginners course in programming, another lesson includes a brief summary with the fundamentals. About Visual Basic features heightened articles on the website but this series will make a unique effort to not leave beginners and students behind.
Where did Visual Basic originate from?
Visual Basic was created by Microsoft, nonetheless it s determined by an early language called BASIC designed by Dartmouth College professors John G. Kemeny and Thomas E. Kurtz in 1964. Since C was invented almost several years later, BASIC is one with the earliest computer languages. Every version of BASIC has become a revolutionary event in programming through the very beginning. In fact, the version of BASIC developed by Microsoft founders Bill Gates and Paul Allen in February 1975 posseses an excellent claim they being the primary personal computer language. The first version was coded in the native machine language of any machine that lots of consider to be the 1st PC, the MITS Altair 8800. Since the very first PC version was written directly in machine language, very little else came before it, not just an assembler language.
The first version of Visual Basic became available in May of 1991. It was revolutionary because everyone could create Windows programs quickly for the primary time. Before Visual Basic, Windows programs were usually written while using complicated syntax of C as well as the even more complicated requirements of Windows. It was a troublesome job for even most experienced programmers. But Visual Basic opened Windows programming for every individual. That managed to get a key part on the amazing early success of Windows. People who didn t survive this era often don t be aware that IBM and OS/2 had almost all the money, most in the customers, and they also made the computers. They had everything ! Microsoft became a tiny, insignificant upstart electrical systems. The programming universe was literally turned the other way up when Windows and Visual Basic was crowned the most successful software system on this planet up to this time.
I did survive it so when I write these words, it s even hard that i can believe precisely how amazing that point was.
But Microsoft hasn't been a business that let history eventually them. They have always made his or her history. In February 2002, Microsoft produced 300 big bet over a totally new technology base because of their entire company. They called Bill Gates, who usually says what he means, a bet this company move. had flopped, in all probability it would have been around for Microsoft.

This articlewillbe while using MCISendString functionvia librarytocontrol the playback and properties of multiple audio filesindependently derived from one of another.You can combination file types, files or clips also.
If you ve never caused the Windows MultimediaCommand Interface before I suggest you look at my beginner tutorial only at that link on an easy step-by-step guide.It shouldget you began with a good understanding from the basicson sending Command Strings using the MCISendString function.
Note : code in this particular article is compatible with all the originalversionsas well as the2005, 2008, VB 2010, and newer versions.
Update Edit: Dec 12th 2014: Just wanted to cover that Microsoft has now released a youtube video about the Community Edition of Visual Studio 2013. You can watch the videoby clicking this link.
Microsoft has announcedtwo new releases or additionsto their Visual platform.A preview version of Visual Studio 2015, plus a new Community Edition of VS2013 ready for downloading. I am personally interested inthe 2013 Community version of VB.Iusually make use of the Express Edition of Visual Basic 2010 for the majority of things and would just like a couple features hard to get at with VB 2010 Express.
So, is Visual Studio Community 2013 just mildly enhanced Express Editions? Nope, certainly not. In fact, it is possible to think of it as being Visual Studio 2013 Professional Edition as outlined by Microsoft. A huge portion of Pro over Express that I desired was the support for Add-ins/Extensions. There are literally countless extensions available including many being completely Free. You can take a look at the extensions by going here
Icons or Images really can enhance your Visual Basic 6.0and Visual applications. Unfortunately a large amount of the Icons you will find either have a price and/or will never allow you to make use of them inside a commercial application. So that is when thislittle postcomes in. I have sources below that s eitherfree for all those uses or free for non-commercial. I will still add sources as is also found. Leave a comment when you have another good source to include here.
Note: While VB 6.0 and maycome with icons, it's your decision something slightly newer ormore unique. That s why I made this post.
This is Part 2 in the Sending Email using SMTP with Advanced Features series. The first series went over tips on how to add multiple attachments for an email message for anyone to download if they view your email. I suggest you make sure that article out only at that web link. Also with the basics of sending Smtp emails you really should look at the article here.
This article will show tips on how to send your email message with Alternative Views. For instance, you'll be able to send an HTML based email message as well as include a Plain Text Only version from the same email. This can help ensure the recipients can look at your email if your email provider or client software only supports Text based emails and the like. All you have to do is build your html based message plus the plain text only message, adding those views for the email message while using AlternateView class.
Note: I do need to mention that these compilation of articles only help Visual Basic 2005, VB 2008, Visual Basic 2010 and Higher since I am utilizing the class libraries in the namespace, which wasn t added Framework 2.0 greater which certainly includes version 3.5, DotNet 4.0, and newer.
First of the to get rolling you will want an illustration showing acouple classes. I am with all the same gmail based codes I used in the initial advanced article due to this series.
This is Part Two in the Advanced Textbox Control Manipulation series. If you haven t already you should take a look at Part 1 of the series. That article showed tips on how to use the SendMessage API call to create a Textbox control Page Left, Page Right, Line Left, Line Right, Left Edge, and go towards the Right Edge on the contents. This Part 2 post will show the way to add the functionality that's outlined below
Note: These codes are simply taken from a good example I to the shows tons of various textbox based manipulating and functionality. Just go to in the Visual Examples page.
This is Part 1 of Sending Email with Advanced Features which will demonstrate how you are able to send a communication message and add not merely one attachment, but essentially as many attachments as you would like. If you haven t already, I recommend you look at this article I made about the basics of establishing and sending email with all the SMTP feature within the DotNET Framework. The code I m using is compatible with Visual 2005, VB 2008, and 2010 since I m with all the classes in the namespace that's made available in 3.5, and 4.0 Frameworks. I am using SMTP and also a Google GMail account to send out the email message.
First of most to get going you will want a instance of any few classes. Below are those you ll should setup
Below include the variables I am using for that classes above.
I ve recenty been making an illustration program with Visual 2008on snapping forms to your edge on the screen. I wanted this software to play a solid wave file if it performed the snapping process. But I didn t need to have making it link to external wave files or anything. So I thought we would embed the wave sound bytes inside the program itself. So this little article will demonstrate how I went about doing that. Here is usually a link to your actual example application that it article is determined by.
The right off the bat you wish to do obviously is determine the wave files you desire to play as part of your application. Remember that this size of file in bytes, willl be contributed to your programs file size. So do not forget that when you decide about what sound files you wish to use.
I also need to mention this article is specific to 2005/2008/2010 far better since I am utilizing the SoundPlayer class.Visual 2002/2003 will must use the PlaySound api thats part with the library. The PlaySound api can enjoy and fit everything in the SoundPlayer class in VB 2005 and better can do. Just more code is involved. I actually found a piece of writing after I started this postthat shows the way to play wave files embedded inside your 02/03 application. Just click here to evaluate it out.
After you could have determined the wave files you would like to embed within your program you need to feature them to any project. There are a few ways to make this happen. The easiest way is usually to copy file after which paste it inside your project. To paste it to assembling your project you just ought to select assembling your project name from the Solution Explorer, the top right panel. Then right click and click within the paste command. Another way is always to click for the Project and click Add Existing Item. Then just browse on the wave files location and select each file you desire to embed. Once the files are added to assembling your shed, you will desire to click on each wave file and within the properties panel Its right below the Solution Explorer by Default. In the Properties panel you will note Build Action. From the build action combo list select Embedded Resource. Do that for every soundfile you added to assembling your garden shed.
Now that you simply have embedded your files for your application, its a pointer to setup the code to experience them. If your more than 2005 then look at this article on with all the unManaged api call PlaySound to accomplish the playback.
You now should access your newly embedded file. You can access it a stream through your programs manifest. Here may be the method which will be used
Part Two on performing various Listview Control tasks for Visual, VB 2008, Visual Basic 2010, and VB 2013.
The listview control has become available to VBers considering that the classic days. continues having its version from the listview control likewise. The control can supply VERY user-friendly features on your program. You can add Groups, Columns, plus more with various display preferences like Icons and Details. The purpose on this post is just to give you some basic code that we ve learned/used over time with the Listview Control.
Note: These codes shouldn't have any problems working together with Visual 2008, and Visual Basic 2010. For this article I am calling my Listview control s name: Listview1. So all with the code are going to be using that name when referring for the listview object. I also set the controls View property to: Details and added 2 columns.
I have a couple of tasks to showrelated to item based sorting. I will show the way to Sort the Listviews item contents by Name, using Ascending and Descending styles. I wish to show the way to shuffle or randomize or possibly it randomise? the items within a listview control. I will also show the way to allow anyone to select one with the listviews columns to sort itemsboth Asending andDesending,
This source code will randomly sort all with the items inside listview control. There may be a efficient way just for this, but this code really does work.
This go through their list contents and reorder the things randomly. Dim r As New Random Dim item As ListViewItem Dim index As Integer You first have to set sorting to None. Now go over the contents with the list. For i As Integer 0 To - 1 Get a randon number to make use of as the index to insert them again. index i, Set to each and every item inside the list. item i First remove that item. item Then insert that item while using the new random index number. index, item Next
OK, this last amount of code will sort the products when a user clicks about the column. You just have to make minor changes towards the code below, based on which column inside the Index you wish to activate the sorting process. The code Has to go within the Listview controls ColumnClicked event.
Private Sub Listview1ColumnClickByVal sender As Object, ByVal e As Handles These codes will check which sorting style is enabled and definately will either set to Ascending or Descending. would be the Index from the column which was clicked. I check for the 1st Column only that is 0 Zero. If 0 AndAlso OrElse Then ElseIf 0 AndAlso Then End If End Sub
You see it really is easy to perform all of these tasks. I don t like the code I made on shuffling/randomizing the items nevertheless it works. Just not sure how good the performance could well be with a thousand items listed.I haven t decided yet of what to do for another Listview Control article. Feel Free to leave a comment for those who have something at heart. Have fun!
Part One on performing various Listview Tasks using, VB 2008, VB 2010, and Visual Basic 2013.
The listview control has become available to VBers considering that the classic days. continues having its version from the listview control likewise. The control provides user-friendly listingfeatures for a programs. You can add Groups, Columns, and even more with various display preferences like Icons and Details. The purpose in this post is to give you some basic code which i ve were required to use as time passes for removing items from your Listview Control.
Note: These codes shouldn't have any problems working together with Visual 2008, Visual Basic 2010, and newer. For this article I am calling my Listview control s name: Listview1. So all from the code will likely be using that name when referring on the listview object. I also set the controls View property to: Details and added 2 columns.
I have three tasks linked to item removal. Removing All, Remove Checkmarked, and Remove the Selected items. Once you might have a basic understanding with the component these task are usually easy. It actually takes almost no code.
Thats all there is usually to it! If I produce more ways or find any other codes associated with removing items then I will update this post. In your next article I consider showing tips on how to Sort items from the Listview control and Shuffle, or Randomize the contents/items on the Listview control. Have fun!
This little article can have you getting the Windows directory/folder using both classic vb and For some reason Microsoft didn t add built-in support when getting the path in the users windows directory 4.0. It is located beneath the: feature. Otherwise I will showa method of getting the windows path inside earlier versions of as well as a way to get your directory path using VB 6.0 and Visual
This can be a simple API call that may give you the windows installed directory for your computer. You just need to make a string buffer along with the api function sets the information you need in that buffer.
Visual Basic 6.0 Declare Private Declare Function GetWindowsDirectory Lib kernel32 Alias GetWindowsDirectoryA ByVal lpBuffer As String, ByVal nSize As Long As Long
Visual Declare Private Declare Function GetWindowsDirectory Lib kernel32 Alias GetWindowsDirectoryA ByVal lpBuffer As String, ByVal nSize As Int32 As Int32
For both VB and This variable is perfect for receiving the path through the API call. Dim winDir As String Create an easy string buffer that'll be passed to your api call to receive the directory is important for windows. winDir Space255 The winDir variable can get the value through the api call. GetWindowsDirectory winDir, LenwinDir Trim the end on the value to take out the unused whitespaces through the string buffer. winDir RTrimwinDir This should throw some text box displaying the windows directory for your target computer. MsgBoxwinDir
When executing the code above, you need a messagebox using the target computers Windows directory. It could be something such as: C:Windows
Like I mentioned earlier Microsoft did not include the Windows Directory being a Special Folder 4.0. But there can be a another easy way to try and do it in the event you don t need to use the API method.
This first way will actually makes use of the Special Folder feature and often will target the Since the System32 directory is often located within the base windows folder all you should do is obtain the parent path in the SystemDirectory.
The code above will throw a message using the parent path to the System32 directory. In my case is returned c:Windows the same as the API version did.
Thereare other approaches to get the windows direcory likechecking a environment variable thatI might add at a later date. The API version is very rewarding for both VB 6.0 and, and also the System32 method works okay RememberMicrosoft included the WindowsDirectory as being a SpecialFolderin Visual Basic 2010 therefore you should use that method when possible. Anyways, thats all!
There could be times when you don t would like your textbox or combobox to indicate the cursor s caret position blinking cursor. Thanks into a couple API calls, its all to easy to both hide and show the caret on the user. Microsoft made availablethe HideCaret and ShowCaret api functions.
I desire to explain alittle more the way the functions operate. Whenever you wish to hide the caret while using HideCaret api call, sayon one ofyour textbox controls, the marked textboxneeds tohave ownership with the caret during the time the Hide Caret function is executed. Whenever the textbox loses ownership from the caret it is going to be reset back on the default setting. For example you call the HideCaret function which successfully hides the blinking cursor inside target textbox control.You then click with a button or some other control that gets focus/ownership with the caret, then a caret/blinking cursorwill see againin the targettextbox if your userclicks or gives focus on the targettextbox again. In other words, whenever ownership on the caret changes in one controlto another then a Caret will reset back in its default setting. So, if you need the caret to alwaysremain hidden in the user within your textbox, then you can perform simple trick to maintain the blinking cursor from being shown even if this changes ownership.
First coming from all, you have to get the code to the two API calls
Private Declare Function HideCaret Lib user32? ByVal wHandle As Int32 As Int32 Private Declare Function ShowCaret Lib user32? ByVal wHandle As Int32 As Int32
Private Declare Function HideCaret Lib user32? ByVal wHandle As Long As Long Private Declare Function ShowCaret Lib user32? ByVal wHandle As Long As Long
The functions are simple to use. All you want to do is call thetwo functions together with the handle from the control whose caret you desire to hide or showin the wHandle parameter like below
The codes above set to Hide/Show the caret within a textbox control.
If you need the cursor to not ever be shown in the textbox control, then in other words the HideCaret code within the TextboxGotFocus event. Like below
Private Sub TextBox1GotFocusByVal sender As Object, ByVal e As Handles 32 End Sub
With the code above, now whenever the textbox control gets focus and ownership from the caret it's going to automatically call the HideCaret function. Thus the consumer should never see theblinking cursor whatsoever.
That s all just for this tip I guess.
A while back I produced simple post on using WMI Windows Management Instrumentaion to test if the operating-system your program was running on was 32-bit or 64-bit. The main trouble with that method its not supported on Windows XP and doesn t show you what mode the job is running in. I created a small example with some other methods that ought to be nearfool proof. I have4 strategies to checking if the application is 32 bit x86 or 64 bit x64 or AMD64 which would be the code name. I also have 5 ways of checking what mode the main system is running in. If you still can t come up with whether you/main system is 32 or 64 bit then I don t determine what to show you. BTW here is really a link towards the earlier post I made on how you can easilycheck if the os is 32-bit or 64-bit using WMI, which applications running on Vista orWindows 7 can use perfectly.
Thereis to much code inside example I created to post here. You should definitely download it and check out. It was created using VB 2005 however the codes is fine in 2003, Visual Basic 2008, and Visual 2010as well. So I will just highlight a couple of ways to determine the job and os mode.
The code belowgrabs a string at a registry key and examines the written text. This is virtually a fool proof technique of whether your cpu is running over a x86 or x64 operating-system. All you must do is check a certain key inside registry like below

If the important thing has x86 then it's 32bit. If the important thing has AMD 64 or Intel64 then Windows is 64 bit. You can also look at the registrykey stext to seeifit contains AMD64 or Intel64. Of course if this contains x86 then your os is 32-bit as well as 64-bit whether or not this contains AMD64 or Intel64.
You can also confirm the registry string on this way. If amd64 OrElse intel64 Then MsgBoxIt Is 64 Bit! End If
I also would like to show an easy way of checking if you is running in 32 bit or 64 bit mode. You can simply check the length of IntPtr. If the pointer dimensions are 4 bytes it is 32 bit. If its 8 bytes it's 64 Bit. This code simply checks in the event the size is above 4 or otherwise not. If its more than 4then its 64 bit. Otherwise its 32 bit. Remember, this method could be the mode atthe application level and never the platform level.
This post wasmainly to provide an overviewofa couplemethods I used inside example program I made. The best thing would be that you download the example and have a look at all with the methods I ve develop or discovered.
I might increase the amount of to this little article inside future. That s all for the time being. Have fun!
Have you ever seen a plan that can open a files destination/containing folder and in addition highlight/select the filename as well within the opened folder window? This will demonstrate you an effective way to complete the same thing. Basically your using shell to gain access to while passing certain command line arguments. All versions of Visual Basic and Visual can certainly interface with while using process., VB 2008, Visual Basic 2010, and higherwill makes use of the same code. VB 6.0 will be needing an additional little bit of code to look at the process. The and argument textpassed on are used for those VB s however.
VB 6.0 will need to provide the APIshell code below to your Declarations section
Private Declare Function ShellExecute Lib Alias ShellExecuteA ByVal hwnd As Long, ByVal lpOperation As String, ByVal lpFile As String, ByVal lpParameters As String, ByVal lpDirectory As String, ByVal nShowCmd As Long As Long
Then call the ShellExecutefunction and pass the right parameter arguments. Here may be the code to start the folder and go with a filename using VB 6.0
ShellExecute, vbNullString, explorer, /select, , vbNullString, 1
Visual has built-in support for running shell based code by while using the Process class. Using this class is very easy. Just add the appropriate arguments and parameters like below
explorer, /select,
Thats all there is always to it! As you are able to see its an exceptionally simplecodeto perform this functionality. Hope this little snippet and article proves helpful to you!
I remember gettingquite annoyed several years ago when I would obtain that error message above. Although it happeneda couple of years agoI decided to publish a brief post regarding it now anyways. You have to remember this error message could very well occur in different scenario s and never just the best way I got it.
I was attempting to setup an illustration using VB 2005 that used personal files I created using C.Whenever I would call a function through the DLL I would get theerror message below
An attempt was designed to load a plan with an incorrect format. Exception from HRESULT: 0x8007000B
It took some time plus the advice as someone to find out why the challenge kept sprouting up.
I use as my main computer an Intel Core2 based Processor/CPU containing 64 Bit support x64 or AMD64, Intel64 is usually a clone of AMD64, which could be the code name. Anyways, I use Windows Vista 64 Bit. That s obviously nota overuse injury in itself.I I mentioned above before I upgraded to Vista 64. BTW this error messagewill popup too when running Windows7 64 Bit, and newer too The I made was determined by Visual 2003 that will onlycompile 32 bitassemblies and was written when I still used Windows XP Professional 32 Bit x86. Of course that s not a problems in itselfeither. Microsoft over 2005 should Not be useful for programmingon any variant of Vista. The problem was once the two joined together. I use Visual Studio 2005 Standard Edition which may targetboth 32 Bitand 64 Bit CPU s and also default the profile is Target CPU:AnyCPU. Since myCPUwas running over a 64 bit Operating System, Visual would make an effort to targetusing 64 Bit profiling as opposed to 32-Bit which was developed in. And that turned out for being the reason I kept getting that incorrect format error message. The program wastargeting 64 Bit mode but library I was using was 32 bit.
I then re-ran the program and also the calls to worked the same as its supposed too. So in case you ever have that Bad Format error message as well as your programming in 64 Bit mode you might try changing the Target CPU to x86 instead on the default AnyCPU Or vice-versa.
Note: Visual Basic 2005/2008/2010 Express Edition IDEcan also target a cpu architecture or platformbut youchange the settingsin adifferent way with all the configuration manager.
Framework has always managed to make it easy to download files. But 2.0 added a fresh Async version in the DownloadFile feature. That basically ensures that if you utilize the DownloadFileAsync sub it's going to download using a separate thread as an alternative to consuming the job thread which makes the job appear frozen. If you used the off the shelf DownloadFile anddidn t would like app s thread bound while downloading, you would need to spawn a whole new thread for your download. So Microsoft managed to make it a little easier to download personal files by adding the DownloadFileAsync method. This article and example blends with Visual Basic 2008, VB 2010, and Visual Basic 2013as well.
Updated 2015: I recently added a little extra code to the article near the finish. The code will add handlersfor the DownloadProgress and DownloadCompleted events.
This is asimple article that may briefly highlight Downloading Files nevertheless the bulk with the code isin a example program I made. There is wayto much code to provide here. The example application will not likely only show the best way to download files while using DownloadFileAsync method, but also the way to add advanced features and capabilities that arenot explicitlyavailable from the DotNet 2.0/3.5/4.0framework.
Download Progress updates like the number of Bytes continues to be downloaded and also the total size from the download.
Calculate the approximate download rate.
Calculate how long it'll take the download to perform.
Keep track of how much time the download continues to be active.
Keeping track with the Peak data transfer speed.
Keeping track on the Average data transfer rate.
Keeping track in the downloading progress when its finished plus much more!
Public Sub DownloadFileAsyncByVal address As, ByVal fileName As String
That method ispart on the: class. Webclient contains some very all to easy to use means of uploading, downloading, and etc.
