I am developing an SDI application on Windows NT 4.0 using Visual Studio 6.0, Visual C++. In this application the Child form calls and creates Modeless Popup Dialog Windows. I need to check and see if the window exists before I try to Create it again. The reason for this is that the Child form can call several windows and they will stack up. If the window does exist I need to move it to the top of the stack of windows.
