    Surely there must be a Win32 API call to do this?

    there are some examples at www.codeproject.com -- but they require COM and Microsoft IE.

    Code:
    #pragma comment( lib, "user32.lib" ) 
    #include <windows.h>
    
    int WINAPI WinMain (HINSTANCE hInstance,  
        HINSTANCE hPrevInstance,
        LPSTR   lpszCmdLine,
        int     cmdShow     
       )
    {
        SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, "c:\\desktop.bmp", SPIF_UPDATEINIFILE);
    
    }

    ill try thx
    *edit*
    doesnt change anything ; though i see a register change

    here is my testing code (though it is pure c) i didn't want to make a new thread

    Code:
    #pragma comment( lib, "user32.lib" )
    #include <windows.h>
    #include <stdio.h>
    
    int main(int argc,char *argv[])
    {
    	printf("Testing...");
    	scanf("%*c");
    
    	SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, "c:\\desktop.bmp",SPIF_UPDATEINIFILE);
    	SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, "c:\\desktop.bmp",SPIF_SENDWININICHANGE);
    	return 0;
    }
    *edit*
    after googling some more ^^

    Code:
    SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, "c:\\desktop.bmp",SPIF_UPDATEINIFILE | SPIF_SENDWININICHANGE );
    bitoperaters are the key here
    thx Tonto for the clue
