I want to create a screen saver in C++ using OpenGL. The command line sent to my app for previewing the screen saver in a small window contains a number which is the hwnd
of the small monitor window in screen saver control panel applet. how can I convert this string to a valid hwnd
?
From INFO: Screen Saver Command Line Arguments :
<HWND>
is a HWND presented on the command line as an unsigned decimal number.
So, convert the decimal number to an unsigned int
and then cast to HWND
. For example:
(HWND)atoi(argv[n])
where argv[n]
is the argument where the HWND value is found.
Pedant's corner: My use of atoi()
can probably be improved, since the number on the command line is unsigned. Feel free.
