Hi guys, ... :) my problem is how to check if a dialog is visible( modal or non-modal ) . Easy, right?
Use IsWindowVisible...!! BUT I want to check it from another class and if possible , not by passing in
 pointers to the dialog object. Meaning, I want to use MFC function/s to get the object instance of the
dialog class with the id IDD_XXXXX and check whether that particulat object is visible or not, and/or call
the object's member functions. There should only be one object instance of that class at any one time...
simply, there will always be only one dialog of that particular class...

Thanks.... have a nice day!!

Regardless of MFC, use the IsWindowVisible with the HWND.  HWND's are unique accross the system, not just to a process.

Commented:
or if you have the HWND you do a


long x = GetWindowLong(hwnd);
if (x & WS_VISIBLE)
{
   /* its visible */
}
else
{
 /* its not visible */
}
