Re: detecting if a modal dialog is being displayed

There is really noway to tell. What you can do is broadcast a message to
either check to see if there is one open or to tell it to close itself.

I have this class that works great for something like that.
http://www.codeproject.com/docview/Broadcaster.asp

If you want to check to see if any are open you can do something like this

1. Define WM_AREYOUOPEN message

2. Make sure that you register the message WM_AREYOUOPEN in all your modal
dialog boxes
CBroadcaster::Register(this,WM_AREYOUOPEN);

3. handle the message in your dialog boxes and return 1;

4. Unregister the message in the destructor of the dialog boxes

5. Here is how to check to see if they are open
    BOOL IsOpen = FALSE;
   LRESULT Result

   CBoardcaster::StartSend(WM_AREYOUOPEN,0,0,Result);
   while (CBroadcaster::SendNext(Result))
   {
      if (Result == 0)
      {
           IsOpen = TRUE;
           break;
      }
   }

if (IsOpen == TRUE)
{
      MessageBox("One dialog box is open");
}

if You want to just close any open modal dialog boxes follow steps 1 through
4 and for five do this

CBroadcaster::SendToAll(WM_CLOSEMODALDIALOG);
