I'm trying to write an application to control the Windows XP desktop!
Specifically speaking, on how to change the background picture on a daily
basis.
Basically, I have 2 problems:
1) I have a book "Win32 Programming API Bible" that instructs me on how
to get a thread for the Desktop, but I get the compiler error "function is
not a member of Application" for GetCurrentThreadID().
I'm using something like this
HDESK hDesktop = GetThreadDesktop( GetCurrentThreadID() )
This will get me the desktop handle:
2.) Once I got the desktop handle, how do I find out which thread controls
the background image, or Active Desktop function as XP calls it.
Thanks,

can use SystemParametersInfo() with the SPI_SETDESKWALLPAPER flag. If you
are working with other image formats, or anything else fancy, then make sure
Active Desktop is enabled and then you can use the IActiveDestop interface.
You misspelled the function name. The name is "GetCurrentThreadId", not
"GetCurrentThreadID".
wrong approach in accessing the Desktop background image. Please refer to
my comments further above.
