Re: Wallpaper

Make a call to the USER32.DLLs SystemParametersInfoA function:

%DLLResult% = File.CallDLLFunction ( "%SysDir%\User32.dll", "SystemParametersInfoA", "20,0,"C:\WINNT\FeatherTexture.bmp",1")

Re: Wallpaper

Am I understanding this correctly?

Dll being called: SysDir%\User32.dll

Function within the Dll that is being called: SystemParametersInfoA

Information passed to the function 20,0,"C:\WINNT\FeatherTexture.bmp",1

What are these three things?

20,0 - Looks like a desktop reference like what would be used in UNIX
C:\WINNT\FeatherTexture.bmp - file you want to set your desktop to
1 - no idea what this information is

If you have a site that would give this info, I would be interested.

Re: Wallpaper

So if I read this right these are the four parameters?

ByVal uAction As Long - 20
ByVal uParam As Long - 0
ByVal lpvParam As Any - "bitmap you want to use"
ByVal fuWinIni As Long - 1

I will continue to look, but do they defind the above functions?

Thanks

Re: Wallpaper

This is the first time I've used the function. I knew it was possible from some sample VB projects I've seen. I haven't really looked past getting it to work to figure out what parameter do what. Which parameter doesn't make sense?

Re: Wallpaper

Hey Worm just so you know you can edit posts again, we turned it back on lately... I think it's within 15 min or something like that...

Re: Wallpaper

Thanks, my brain can definitely go faster than my fingers, and it helps to let them catch up [img]/ubbthreads/images/icons/smile.gif[/img]. 15 minutes should be about enough time. Depending, of course, on how much caffeine I've had. [img]/ubbthreads/images/icons/smile.gif[/img]

Re: Wallpaper

The 20 tells the function that you are wanting to set the Desktop Wallpaper.

Then the filename as you suggested

The 1 is to tell Windows to update the INI file, if you set it to 0, it wouldn't

At least thats my interpretation.

Re: Wallpaper

You won't be able to use .jpg files on the desktop unless ActiveDirectory is enabled, and even then I'm not sure if that DLL will be able to perform the switch. (That functionality depends on IE to some extent.)

You could perhaps convert the jpgs to bmps at run time...there are probably a few free command line image conversion programs out there that you could use.
