I am using using Visual Basic Express edition 2008. How can save / save as my project in different version when I make changes to the code? i.e. save the same project whenever I make a change in the code and keep the previous version of the code for future reference?

I've deleted the original code, but to be specific, when I developed a form using Buttons and Textboxes I didn't place them in any specific order. The result was that as the user clicks the cursor, it would bounce around the page in what would appear to be a random sequence, but in fact was going to the next button/box in order of how it appeared in the code section of the form. Naturally, my first inclination was ..... OK, that's how it's going to be, I'll just cut and paste the code in the order of how I want the cursor to move. What happened was I generated several errors and the file would not compile. I can find no information on how to properly cut/paste code sections without generating these types of errors. BTW, I did try the focus() function and it did direct the cursor to the appropriate box, but it also only allowed 1 character to be entered in the textbox and summarily directed the cursor to the next box.

Is VB Express 2010 slower to compile and run that older versions of VB Express? I've installed it this weekend and it seems a little sluggish on my quad core computer with 1 gig of RAM. I have VB Express 2005 installed for my students at school and it seems to fly just fine. Those school computers are older P4s with 512k of RAM.

I'm just using the default SQL Server Express in my vb 2008 express edition as my database server for my database operation. When I tried to update the records on my table I got a runtime error which indicates the error on this line 'myCommand.ExecuteNonQuery()'and it highlights a yellow background on it. The runtime error says "SqlException was unhandled: An expression of non-boolean type specified in a context where a condition is expected, near 'Number'. ".

I am working on a project for school and I am encountering several errors in my code relating to the numeric up down boxes I have in the application. I have inserted my code and the error list below. I'm sure that it is probably something really simply but I am learning the language on my own and I am a little stumped here.

To the board: Lately I've been getting Runtime error 3447 ("The Jet VBA file (VBAJET.dll for 16-bit versions, or VBAJET32 for 32-bit versions) failed to initialize when called. Try reinstalling the application that returned the error") when attempting to open a certain program (not one that I designed, just downloaded and installed). I installed this program in January 2009, but this error began happening only this past July. someone else to information about the files vbajet32.dll and expsrv.dll. One site said that the problem was probably caused by the file expsrv.dll being absent, but I checked my System32 folder, and it's there. As far as I can tell, it has always been there (the computer was made in 2008, and as I said the program had always worked before). Vbajet32.dll is also there. I tried uninstalling and reinstalling the program, but error 3447 still occurs. I also tried uninstalling the program and installing an older version, but 3447 is still there.
I tried replacing expsrv.dll, thinking it might have been corrupt, but that didn't help, and I cannot register that dll anyway. I can't figure this thing out. Both of the files are there, and I didn't change any settings or anything anywhere between last January and this July. By the way, I am on Vista.

If I create a DLL using VB 2010 express can it be used by previous versions of of .Net (3.5, 2.0)? Will the DLL use .Net 4.0 components, which is what I want. I don't see a way to force that to be the case.

In a VB.NET (3.5) Windows Forms application that, among other things, creates Microsoft SQL Server Integration Services (SSIS) Packages, we want to be able to support the creation of packages both for SQL Server 2005 and 2008. To create packages compatible with SQL Server 2005, functionality from external Microsoft assemblies with the specific version of 9.0.242.0 are needed, and to create packages compatible with SQL Server 2008 the same assemblies need to be referenced, but with another version number, 10.0.0.0. There does not, unfortunately, seem to be backwards compatibility in that SQL-2005 packages could be created using functionality in the newer 10.0.0.0-assemblies.
Today, we have a very inefficient way of handling this. For each new release of the app, we have to: Build two different versions of the app, one "2005-compatible .exe" and one "2008-compatible .exe", by: Manually add/remove the specific 2005/2008-references at project level (properties).Comment/uncomment respective code that is not common between the two versions of the same assemblies.At installation time of the application, figure out if the machine runs SQL Server 2005 or 2008 and then install the corresponding build/version of the app.We do not ship or install any assemblies with our application but instead rely/pre-requisite on that the machine on which we install our software has either the 2005 or 2008 assemblies installed in its GAC (depending on whether SQL Server 2005 or 2008 is installed there).
I have learned that with a few tricks it is possible to reference and use identically named assemblies with different version-numbers in the very same project. But even then if we manage to do this, since the client machine always will only have only one set of the assemblies installed in its GAC (9.0.242.0 or 10.0.0.0 versions depending on which SQL Server version it has installed), and we need to reference both sets in the project to have "full support" for both 2005 and 2008, how can we avoid potential "missing dll-messages" when the client runs the app? We do not feel very excited about having to ship/install 2005-assemblies on a 2008-server and vice-versa, that would never be used by the application, even if this would constitute a solution to the above problem.

I create a new Windows Forms application and add an AboutBox form which is built-in into Visual Studio. I add a button to Form1 to show the AboutBox when clicked.The AboutBox form has a label with the text "Version" on it. The following code is supposed to add the application's version to that label at run-time:
Me.LabelVersion.Text = String.Format("Version {0}", My.Application.Info.Version.ToString)When the application version is changed in the Publish tab of the My Project form to 2-0-3-6, the version on the AboutBox at run-time stays at 1.0.0.0 (of course after rebuilding).
Even when the application is published to the desktop, it still does not work. It does, however, reflect the correct version number in the title of a subfolder in the Applications folder that is created when the application is published.

I have two slightly different versions of my VB applications that I would like to publish simultaneously. The differences are minimal and mostly include GUI and some internal logic. Incorporating changes into a single application is not an option right now.
I tried publishing and installing them separately but the latest installer always overwrites whatever has already been installed. For example, if I install App v1, then App v2, only App v2 will be visible. If App v1 is installed after App v2, only App v1 will be visible. What I want to have is to have them both installed. I am using Visual Studio 2008.

I have a COM application (X) that references various .NET assemblies. All the .NET assemblies, with the exception of one (Y), were created a while ago and reference an earlier version of a 3rd party component, say version 1. The other .NET assembly (Y) uses a later version of the 3rd party component, say version 2.When I install the COM application (X) on the target pc, version 1 of the 3rd party component is installed in the installation directory of the COM application. The .NET assembly (Y) is installed into its own directory on the target pc and has version 2 of the 3rd party component installed in its installation directory.
When I run the COM application (X) and try to launch (Y), I get an error because I guess the COM application is forcing (Y) to use the version installed in its app.dir, in this case version 1 as opposed to version 2. Is there any way around this? It seems a bit much to have to rebuild all the projects that reference this assembly just to sync versions.

I got a function that reads memory of another process and then uses it in different ways. To prevent the GUI from lagging, I start a new thread and executes the code in it. It runs fine, but after a while, aprox. 20 minutes, the applications stops to work and an OutOfMemory exception pops up. The thing is that the memory use of the application isn't higher that 10mb and I can't notice any high increaments either. I have tried everything to find out what is wrong, but it seems to be impossible.

But there are ALOT of labels (about more than 300) and typing them out (or selecting them in the menu) consumes alot of time. Is there anyway to put the rest of them? I have about 8 groupboxes with these labels that need to be changed (there is another one that doesnt need this) so they are labels inside of groupboxes.

This is giving 2 errors:
Me.btnBackpage_Click = Delegate 'System.Web.UI.WebControls.CommandEventHandler' requires an 'AddressOf' expression or lambda expression as the only argument to its constructor.
And
mybtn.Command = 'Public Event Command(sender As Object, e As System.Web.UI.WebControls.CommandEventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.
