Is there anything that looks like it might not be supported yet. Anyone have any ideas??

Tum please can I get your project files for VS they would help! – just zip the whole lot up and email if you can.

 

 

the relevant code is:

 

public bool ProcessEvents(bool waitForEvent)

                  {

                        Win32.Api.MSG message;

                        if (!waitForEvent)

                        {

                              //return false if there is no message or the quit message

                              if (!Win32.Api.PeekMessageA(out message, IntPtr.Zero, 0, 0, Win32.Api.PeekMessageType.PM_NOREMOVE)

                                    || message.message==Win32.Api.WindowsMessages.WM_QUIT)

                                    return false;

                        }

                        //process the message

                        if (Win32.Api.GetMessageA(out message, IntPtr.Zero,0,0)==0)

                              return false; //occurs on WM_QUIT

                        Win32.Api.TranslateMessage(ref message);

                        Win32.Api.DispatchMessageA(ref message); 

                        return true;

                  }
