I added the breakpoint as described and it never is triggered, however, I still get the same runtime error, so either it's not setup right (which is possible but the procedure is simple so it shouldn't be) or it's never changed. Another thing is if I use the close button in the top-right, it closes fine but I've always closed with File->Exit, and that function simply calls exit(0); and then crashes.

Messages 0 through 1023 are reserved by the system so it seems weird that nMsg would be 2. Make sure you are not doing something like SendMessage(IDCANCEL) to close the window. I have seen people make that mistake before.

Nope, when the user goes to File->Exit, the function called by the menu click just runs exit(0);

Try using PostQuitMessage(); instead.

wow, if only my other problems left to resolve quit as easily as that one did, good call. Now I don't have to click through any more runtime errors that always occur but I used to not know how to do anything about it. Thanks alot.

Call PostMessage(WM_CLOSE) instead. PostQuitMessage() does not shut down an application properly as other messages might be initiated by the shutdown operation and those messages, along with any other messages that might be in the queue, will not be processed.

I have a Visual Studio solution that contains an MFC executable project and a .NET C# class library project with a Windows Form. When I instantiate a simple C# Windows form from the MFC program, then, on closing out the form and exiting the MFC app, I receive an assert in the CCmdTarget destructor (line 48 cmdtarg.cpp) because m_dwRef is > 1. I have recreated this with the simplest MFC and C# windows from that I can make. I still get this assert. Other than the assert on close-out, everything else works fine. The form is instantiated from an MFC CDocument class object using the following code:
FormX *f = new FormX();
f->ShowDialog();
What's my problem??

Where are you deleting f?

Thanks, Anon. I was not deleting 'f' thinking that it would just get garbage-collected, but I can see the problem with that.
Since deleting 'f' requires a destructor, I have added the 'delete f;' code to the MFC object and a destructor '~FormX(){}' to the form's code. When I compile the MFC code, I get an C3841 error on the delete statement which says "C3841: illegal delete expression: managed type 'ClassLibrary1::FormX' does not have a destructor defined." I am still missing something?

Sorry man.... can't help you there. MFC->.NET interaction I haven't delved into.
No garbage collection in MFC to help you out with the new/delete operations. But I imagine that your problem is a result of your instantiation of the FormX object and MFC not knowing how to release it properly. At least it's a place for you to start looking.

I have a driver that provides low level access to the hardware, but it does
not function for all users. It only works when logged in as the
administrator.
How can I tell windows that the driver/program has priveledges to run the
driver to perform the low level functions (inp/outp)?
I am not a professional software writter, obviously, so if you could provide
a piece of code this would help.
I have tried several examples from codeguru and codeproject that were
suppose to allow this type of situation, but they do not work. No matter
what I try, I cannot get windows to let the driver run with priveledges in
non-administrator mode.
Many thanks for your help!!!!

If you create MFC7 applications using C++.NET, are the projects compatible with the 2002, 2003 and 2005 versions ?
It's just that we have a couple of copies of 2002 and I would like to make sure people can exchange files and projects (just for MFC).
Thanks.

Hi
I´m creating my own "MessageBox" -like class, derived from ::Form.
I want the messagebox to close when I press the "OK" button , i.e. to work as if the "x" (close)-button was pressed.
I don´t know where to find the code for this.
Can anyone help?
sincerely

All messageboxes are like that...
Call
CDialog::OnOK(); on the click event of your OK Button..
Ninety-eight percent of the thrill comes from knowing that the thing you designed works, and works almost the way you expected it would. If that happens, part of you is in that machine.

How to add a timer delay in a dialog based application in visual C++?

See SetTimer() and KillTimer() to set a periodic low-resolution timer. To suspend execution, use Sleep().

For each instance of the control I am calling its draw function with different parameters but the multiple instances all display with the same parameters. What is happening and how do I get around this problem.

Use CString::Mid() to extract a substring from a CString.
