Hi there,
My requirement is that I want to recevie a messgae when a
application is launched....and do something...
so what i did i setup a WH_CALLWNDPROC hook ....and i listen for for
WM_CREATE and /or WM_NCCREATE...

I get message whenever application get's created.. and I do whatever i
want ...

CWPSTRUCT *wps = (CWPSTRUCT*)lParam;
HWND hWnd = (HWND)(wps->hwnd);

if(wps->message == WM_NCCREATE ) //WM_CREATE )
{
wchar_t processName[256];
::GetModuleBaseName(::GetCurrentProcess(),0,processName,
256);
if(::wcsicmp(processName,L"NOTEPAD.ExE") == 0 )
{
// do What i want ...glow//hilight
windows change priority etc...
}

}


till here everything is working fine ...no issue ...but i want a
message which is sent exactly once ....
when window is created for the first time ( when application is
launched) ....but I am getting these two messages
even when I right click on notepad in taskbar, to invoke the system
menu, this is not desired.

Can anyone of you tell me which message exatly i should listen for ?

Because you get the WM_CREATE from the menu window ("#32768")
You can test GetClassName()
Another method is to use WMI events with Win32_Process class
