I'm working on an app in VS 2010 on wind2008. It's a .Net 3.5 app that use .Net 2.0 library.
I change all Frameworks to 3.5 .Net and uncheck "Enable the visual studio hosting process"
But When I debug my solution I got this error :

any idea , beast regards
Exception Code: c000041d
This tells the tale, that's STATUS_FATAL_USER_CALLBACK_EXCEPTION, "An unhandled exception was encountered during a user callback". Your program threw an exception and it wasn't handled. Which normally automatically breaks into the debugger and displays the Exception Assistant.
However, the exception occurred at a very awkward time, just when the operating system was in a state where it cannot afford to go through the normal rigamarole that it goes through when a thread dies with an exception. This kind of mishap usually occurs when the callback was triggered by 32-bit code but the exception occurred in 64-bit code, there's no good mechanism to marshal 64-bit exceptions back into 32-bit code, the exception information cannot be properly interpreted by such code since it includes 64-bit pointer values. Or the other way around. Windows messages generated by the window manager tend to fall in this category. Beware that this is just a rough guess at the reason, you need to find the real one.
You do so by forcing the debugger to stop at the code where the exception is thrown, before the operating system is asked to deal with it. Use the Debug + Exceptions dialog, tick the Thrown checkboxes to force the debugger to stop at the throw location.

When I clicked the X button to close a program (say it is MYAPP), a dialog popped up saying:
MYAPP has stopped working
Windows can check online for a solution to the problem."
But actually the application had already exited.

How does Windows detect if a program is "stopped working"? Does it indicate the application throws an exception or a dead lock?
Windows Error Reporting (WER) will catch unhandled exceptions. It won't catch a deadlock. That dialog box that pops up when a program "stops working" is a WER crash-dump being taken (or it communicating with a MS server to see if it wants to take a crash-dump, etc.).
There are several ways to debug a crashing program that are tried and true (although arduous). Some of these include:
Using GFlags to launch Visual Studio or WinDbg
Including code in the program to launch a debugger
In this case with WER, you could turn on local crash dumps, and then, as long as you have the symbol database (pdb) file, you can debug from a local crash dump. You can read more on taking local crash dumps at Collecting User-Mode Dumps.
I've an exe (app1) which is written in VB6, this is called from another VB6 application (app2). This was working all these years and recently started crashing. When I'm riunning app2 and where app1 called is crashing with the following error.

This is crashing only in some machines, it's working in machines with same configuration.
I've tried disabling DEP for this exe, that doesn't help too.
These shouldn't occur in a VB6 program unless it uses API calls in a cavalier manner. Such a program can run just fine until something in the data it works with causes it to fall over on one of these access violation errors.
See What is a C0000005 crash?
The app in question uses both native and managed code. The managed code provides just the UI layer while it links with a native dll which performs bulk of operations. The native dll links with some other static dlls. Now the issue is when I run the app it crashes non-deterministically. When I debug the app under managed code debugging, it shows that a particular function in the native code threw an "SEH" Exception. Stack trace just shows the current function. The error code that I get in the SEH Exception is EFAIL.
However the app runs fine every time under native debugger. The function which throws the SEH exception is single threaded. It doesn't uses any resources which may be accessed in any other thread. What could be the possible cause for this behavior? How should I go about detecting the origin of the exception in native code. Stepping-in under the debugger doesn't helps since the issue doesn't shows up when the app is running under the debugger.
I am using visual studio 2012.
Are you using DirectX?
SEH Exception occurres when DeviceContext is using from many threads
at the same time, because DeviceContext isn't thread safe.
I can change one small thing commenting/un-commenting it and VS2005 will either crash or not crash for no additional reason in either case.

Since the above is really of no help to me, is there some way I can diagnose what's going on? All I'm able to get out of debugging the compile crash (in VS2005) that is that there is a corrupted heap.
Some options you can try out:
You can get a log when booting Visual Studio using /log as attribute.

Creating a crash dump

Uninstall ReSharpen (if you use it)
Reinstall Visual Studio
Create a new Windows User and see if you get the same trouble
Ehh.. Solution: Get rid of the outdated buggy IDE and upgrade to a more recent one. Went to VSC15. No crashes since.

I am not a professional programmer and I need not to know whether this happens because my poor programming skills or something else..
Exception code c0000005 is an access violation, also known as general protection fault. The program is reading from, or writing to, an address which is not part of the virtual address space. A very common cause is that you are de-referencing a stale pointer. In other words, the pointer was once valid, but you have subsequently freed it. Then later when you attempt to access it, an exception is raised.
The exception is faulting in ntdll.dll which is a system DLL. That means that something in your program is passing invalid data to a system API.
In order to solve this problem you will likely need to run under the debugger and let the debugger break at the point in the code where the exception occurs. Then you can attempt to work out why the memory that is being accessed is invalid.
That's something that you can do, but we cannot. You have the code, we do not. So, we can't give you any more help than this. In any case, there's no need to despair–these problems are usually easy enough to solve with the help of a debugger.
Sometimes delete the contents of your build directory and try to compile again just to make sure nothing is caching.
