hi, i want to write a program to change the wallpaper immediately when some button is clicked. i use vc++. does any 1 know a function call or registry tweak to do this.

I would think if you knew the registry key then CRegKey would be the way to go... Just call SetKeyValue of the key containing the path to the bitmap

or, you can use IActiveDesktop::Set(Get)Wallpaper... This shoud do the trick if you're using MFC...

But, if you are more in Windows api, a call to SystemParametersInfo function, with uiAction parameter set to SPI_SETDESKWALLPAPER and the pvParam set to a string pointing to the location of the bitmap.
You should check MSDN for a complete reference about this function... [red]Nosferatu[/red]
