Hello,

I need a wnd SYSCOMMAND that gets fired reliably when clicked on the window which is sitting on the taskbar or when that window enters in focus after pressing Alt+tab
I have already tried below commands but it dint help me.
some of the commands are fired but not reliably.

         const int MYKEYID = 0; 
         const int WM_MOUSEACTIVATE = 0x0021;
         const int WM_HOTKEY = 0x312;
         const int MOD_ALT = 1;
         const int MOD_CONTROL = 2;
         const int MOD_SHIFT = 4;
         const int WM_SYSCOMMAND = 0x0112;
         const int SC_MAXIMIZE = 0xF030;
         const int SC_RESTORE = 0xF120;

if (message.Msg == WM_MOUSEACTIVATE || (message.Msg == WM_HOTKEY && message.WParam.ToInt32() == MYKEYID) || (message.Msg == WM_SYSCOMMAND && message.WParam.ToInt32() == SC_MAXIMIZE || message.WParam.ToInt32() == SC_RESTORE)))
{
     FormClicked();
}
