Changing desktop wallpaper 1

[donvittorio]

Hi,

I'm writing a little program to change the desktop wallpaper on a Win 2000 machine. I am changing the registry settings for stretch, tile and centre okay and I'm using SystemParametersInfo to set the wallpaper okay using the following line

SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, Pointer(Filename), SPIF_UPDATEINIFILE)

but the change is not applied immediately. To get the change to actually appear on screen then I have to go into the desktop properties dialog screen and apply the change manually (or reboot the machine).
Does anybody know how to apply the change so that it is effective immediately?

Thanks

Steve

Ah-ha, I've found the answer. I need to change the last parameter to be SPIF_UPDATEINIFILE or SPIF_SENDWININICHANGE, i.e.

SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, Pointer(Filename), SPIF_UPDATEINIFILE or SPIF_SENDWININICHANGE)

and then the change is applied.

I hope you guys weren't suggesting that I awarded myself a star.
Hang on a minute, can you do that? That gives me an idea...

I don't think you can give your self a star. I don't have the 'Thank lespaul for this valuable post' on MY posts!

You are right Leslie, you definitely cannot give yourself a star!
