Hi, I have made a DLL in Visual C++, and have been using it in Visual Basic. Now after several updations of my DLL when i try to add the reference of my DLL again it gives a error box "Can't add a reference to the specified file".

Hi, i have inherited a class from CEdit, and want to send my application a user defined message from this class. i have used PostMessage function for that reason from my class's LBUTTONDOWN message. The message is captured by my window (a dialog box that has an edit box linked by a variable of my class) and works well while i work in Debug configuration, but causes an unhandled exception in Release Configuration:confused:. I would be obliged if any one can help me.. -------- THE CODE SAMPLE: -------- Dev.
