  Hi friends!

  I write both vc++ SDI and MDI application. In dialog based i write my code OnSysCommand() as :

  void CDlgBaseDlg::OnSysCommand(UINT nID, LPARAM lParam)
  {
  

  if ((nID & 0xFFF0) == IDM_ABOUTBOX)
   {
       CAboutDlg dlgAbout;
       dlgAbout.DoModal();
   }
   else if((nID & 0xFFF0) == 61472) //AFX_IDS_SCMINIMIZE
   {
       //my Msg here when window is minized  
  
  
  
  
  
  
  

   }
   else
   {
       CDialog::OnSysCommand(nID, lParam);
   } 
  
  
  
  

  If i use OnSize(), when i click trayicon, my program is just activated and not showed. I don't know why. That's why i use OnSysCommand(). But it doesn't work in SDI and MDI application. PLs advice me what i should do.

  Thanks in advance!

  Hi michael

  First where is your ShowWindow(SW_NORMAL).

  Second most of the system tray programs hide their main window instead of minimizing it. so you have to use OnSize()

  That's why OnSize did'nt work in your code because you have used minimize option

  Check this Article with code explanation (how to use OnSize) or click here to download the Source code
