Hello,

I would guess that this is handled by the Windows Registry. You can make what is called a .reg file that inserts information into the registry. You could write a C++ code to prompt the user the desktop options, and then have the C++ program make the registry edit. You would also need to specify if you want the current user to only receive the edit, or the whole bunch.

Do a search on Windows Desktop Registry. See what you find.

Actually you can do this programatically fairly easily...
Using Windows API's SystemParametersInfo with SPI_SETDESKWALLPAPER.

I don't program in Win32 anymore, so the if you get stuck try looking here:

You should be able to figure out which constants correspond to the given values in the example.

Have fun!

Hmmm...well it appears that you're in Visual C++ so what kind of project do you think that a person might make in a C++ IDE? This isn't rocket science my friend....

After nearly 3 YEARS, do you really think that the OP cares?

Haha, I found this while looking for something else on Google. I never even checked the date. I'm sorry.

could you give me an example of how a program that changes the wallpaper to flower.jpg, would look like?

You should read Microsoft SDK samples, where the Wallpaper changer exists for more than 15 years...
