window maipulation(C++) 2

[Leibnitz]

I will like to know how to close a window wen you know his title.
Exemplence you've open "My documents" by this code:
ShellExecute
(HWND_DESKTOP,open,"c:\\my documents",NULL,NULL,SW_SHOWNORMAL),
how to close it ?

Use FindWindow API to Find the Window by it's name. Then you get the window's HWND if the system find's it, otherwise NULL is returned.

HWND FindWindow(
LPCTSTR lpClassName, // class name
LPCTSTR lpWindowName // window name
);

To know lpClassName of a window beforehand use Spy++ that comes with Visual Studio.

When you have the HWND of the window just do:
::SendMessage(myHWND,WM_CLOSE,0,0);

HTH, s-)
