Debug-only AfxMessageBox

Hi, I am looking for a function like AfxMessageBox, but will only available in Debug Version, to display some error messages. I have thought of TRACE, but it will only dump the error message in the output box, not pop up a messagebox to pause the execution of the program. Does Visual C++ provide such a function?

You could wrap your call to AfxMessageBox() #ifdef _DEBUG, but that's an unusual way to debug. What's that doing that the debugger can't accomplish?

Use ASSERT macro, followed by a comment describing the error.
