I'm developing a VB Window's Forms application in Visual Studio 2010. I choose an object out of the forms toolbox, say a chart. Then I adjust the properties in the properties window to get what I want. Is there any way I can see the actual code that generates those properties?

You could open the containing folder for your project and then find the <formname>.Designer.vb file and open that file as a text file. I do not think that it shows up in your solution explorer by default.

Visual Studio offers a "show all" button in the solution pane.

recently I converted a database migration utility from VB(VS6 sp6) to VB.NET(VS 2008 SP1). It is ported succesfully. I am able to open it development M/C. But if I am trying to open the same application in installer M/C.(Fresh machine) my application is crashing.
can anyone let me know what run time dll should be included so that it will work fine.
System Details
1: XP SP3

The .NET Framework should be included; the same version that you used to develop against. You can't install just "a few dll's", as most of them have quite some dependencies.
Does your installer have an option to see if there's a .NET framework?

1) Open VS 2008 and load the project.
2) Right click the project name in solution explorer and select properties.
3) Select the Compile tab and click the Advanced Compiler Settings
4) Check the target Framework version
5) Install that Framework version on target machine
6) Build project and copy EXE file to target machine

vb6 sp6 working in virtual XP machine under win 7
This setup has been working fine and the projects have existed for years but a couple of them have started failing to compile
They all compile and run ok with Control F5 (Run with full compile) but when you use the File->Make xxxxx.exe option it works for a while and the progress line of "Writing EXE" partially colours blue and it then stops with
Microsoft Visual Basic, "Unexpected Error" Ok Help
Help tells me I may have a hardware or software error. gee you think
At least one of the failing projects hasn't been modified (using sourcesafe so I can be sure of this) since it last compiled ok
Other projects compile ok
Does anyone have any ideas where to look for more info?
EDIT: Things I have checked
There is plenty of free disk
running the compiler from the command line gives the same result
a repair install doesn't change anything
repeat install of sp6 didn't help

In 2008, as that's when extended support for VB6 ended 
FWIW;
- Make sure you registered all the controls that you're using
- Compile under Windows XP, or download XP-mode for Windows 7
- Keep removing code (comment it out) until you got something that compiles again
- Start migrating to VB.NET; the compiler is free, and you can mix VB6 and .NET code, using the Interop ToolBox from Microsoft.
- Check if the VB6 IDE created a logfile under C:\Windows\System32, and check the EventLog for clues.

2008 is quite recent really
Thanks for the suggestions
it is possible that upgrading office broke it but that had to be done as office was broken, I will have a look when I did that and perhaps try another virtual machine
I am running under XP, in a virtual though
the code hasn't changed on at least one of the projects that is now failing to compile
I will investigate interop
no IDE log file unfortunately

Read that again; extended support ended four years ago.
Imagine your virusscanner being outdated four years.

..and now you have to re-create a working compiler-environment. And those Office-dependencies are usually tied to a specific version.
I suggest you create a minimal build environment in a VM, and keep it clean. That probably involves in listing all your external references and verifying their existence and that those are the correct versions.

Your right of course and my comment was not intended to be serious but...
Why should it worry me if the extended support that I never used anyway has expired. As long as the program is a valid method of producing binaries (maybe I should keep quiet about that is it isn't at the moment ) then I see no reason why I shouldn't use it
I like the language and, as the largest project is up to 140,000 lines of code, moving to another development environment is not at all easy but as the whole things changes every few years anyway it is hard to see the point. It would be interesting to know the overall number of developers currently using vb6, vb2005, vb2008, vb2010
I am not a luddite and keep up to date with technology but my grandads King Dick socket set still seems to work as well for me as it did for him when he bought it quite a few years ago
Thank you for your helpful advice

It should worry the owner of the project; if your project is written in a dying language, the project will die along with the language. Unless you have the sources to Windows XP and VB6 (including the dependencies)
Mike Deeks wrote: I like the language and, as the largest project is up to 140,000 lines of code, moving to another development environment is not at all easy
It IS easy - it's also a lot of work, but it ain't complex. The longer you write new code in VB6, the more you'll have to migrate.

Hehe, aight - if it ain't broke, don't fix it. You got a good point there. And yes, I admit that even 16-bit apps from Win3.1 might still run on Win7, but if something goes wrong, you're (almost) on your own.
You can't compare VB6-code to "pascal code", or any other "older" language; VB6 is tied to Microsoft, is proprietary (they own the language), and it will die if they do not support the language actively.

Make sure the folder is writable and that the target .EXE file isn't locked (running) or, even better, doesn't exist already.
|
|
|
|
|
unfortunately all checked and even changed the folder just in case
some projects compile and some give the "unexpected error"
I will have to go through and check references/components to see if there is any commonality
|
|

Either that or the VB6 compiler is finally rotting away. Good riddance!

When you build COM objects, those COM objects get registered. And that means: writing to the registry in a part where a user must not write.
Hence my idea: Do you get the same error when you run the IDE in elevated mode?
|
|
|
|
|
don't think you can elevate on Windows XP SP3
and I am an administrator on the PC
but good thought
|
|

True, the virtual machine has its own registry, and with XP, an administrator can write to that.

On MSDN, I found code that is designed to change between multiple sound cards on a PC. I need to do this in .NET. I attemped to translate the VB6 code on MSDN (see link) into .NET but wind up with a PInvokeStackImbalence exception.

mciSendCommand(0, &H80D, &H800000, Parameters)
PlaySound("C:\thermo.wav", 0, SoundFlags.SND_FILENAME Or SoundFlags.SND_ASYNC Or SoundFlags.SND_LOOP)
End Sub
End Class
Can Anyone assist me?
Thanks,

When calling native code from managed code, stack imbalances are most often caused by applying the wrong "calling convention" (which says who, caller or callee, is responsible for cleaning up the stack). You will need to apply an explicit DllImport directive and specify the correct calling convention, most likely StdCall.
You will find an example here[^].
I wrote a little article[^] on P/Invoke, unfortunately it isn't finished yet, so it doesn't have the details for VB.NET; you might find it useful anyway.
