I am trying to prevent multiple instances of my application using C++ 
Builder 6.

I have done this before with C++ Builder 5 without problem. The code 
template I am using is:

 ::CreateMutex(NULL, FALSE, "YourMutexName");
     if ( GetlastError() == ERROR_ALREADY_EXISTS )
     {
         // Found another running application with the same mutex
         // so one instance is already running.
         Application->Title="Testing";  // prohibits finding this instance
         HWND FirsthWnd, FirstChildhWnd;
         FirsthWnd = ::FindWindow("TApplication", "YourApplicationTitle"); 
// see Application->Title or Options|Project|Application Tab|Title
         if (::IsIconic(FirsthWnd))
             ::ShowWindow(FirsthWnd, SW_SHOWDEFAULT);
         ::SetForegroundWindow(FirsthWnd);
         FirstChildhWnd = ::GetLastActivePopup(FirsthWnd);
         if (FirsthWnd != FirstChildhWnd)
             ::BringWindowToTop(FirstChildhWnd); // A pop-up is active so 
bring it to the top too.
     }
     else
     {
         Application->Initialize();
         Application->Title = "YourApplicationTitle";
         Application->CreateForm(__classid(TYourAppMainForm),&YourAppMainForm);
     }

This works fine except when the first Instance is minimised. When loading a 
second instance the code failes to restore the first instance because 
IsIconic always returns false.

Does anyone know why this might be the case.

I'm running on WinXP SP2.

Out of interest if I run a second instance whilst my project is open in BCB6 
with the Main Form's design Window minimised then the Forms design Window is 
restored??


Thanks,
