I would like to write a .bat file to cycle my wall papers... The bat
file would be scheduled to execute every 30min. The bat file would
import a key to the registry that would change the call paper...

When I tried to manually change the key HKEY_CURRENT_USER\Control
Panel\Desktop
and exit the registry editor, the wall paper does not change...

How can I enforce the change...Refreshing the desktop did not solve
either...

Please help...

I would not like to use the commerically available softwares as they
contain more features than I need and consume some overhead...
Moreover, I would like to proceed with this as a technical problem...

Thank you.
 
AFAIK there's no native way to do this.

I just discovered a few regedit switches that works on win2000 sp4...

regedit /s regfile.reg -Silently imports the regfile.reg
regedit /e regfile.reg "Key Name" - Silently exports the key "Key Name"
to regfile.reg

This might help me cycle my wallpaper on each boot by putting a bat
file in the start up folder. I will have to write a small programme
that could dynamically generate a regfile to import.

I had to look on some sites to find the regedit command line
options...win2000 sp1 showed the command line options on regedit /? as
far as I remembered... But the sp4 does not...Though they work.

I'll try this... If it works, I'll post the solution here....

Doubtful without restarting the shell.

my target.

That should work, no problem.

As you have already found out you need the user to logoff and logon
again for the changes to take hold... but you can get around that with this:

RunDll32.exe USER32.DLL,UpdatePerUserSystemParameters ,1 ,True

Run it after the registry change in your batch file.

web reference...

Thanks a lot...

| You're welcome. You can do lots of things with rundll32.exe and the
| right dll. A simple search on the internet with a few keywords will
| yield lots of information. It can lead to interesting finds like this:
