Wallpaper slideshow

[james3mg]

OK, so this is kind of a "me too" script like ezzetabi's wallpaper changer, but with a few more controls I wanted (and honestly, I didn't realize he had written one, I just saw his function on another thread and wanted to write this). This fairly-configurable script will rotate your desktop wallpaper automatically, as often as you choose. It stores minimal config data in your user's AppData directory under Wallpaper changer. (what folders are included, what files are excluded, and time to wait between changes). This works especially well on Vista with it's nice landscape wallpapers, but I really wanted to be able to easily exclude specific pictures because some of them are quite horrendous also.

When you first fire it up, it will automatically assume you want the wallpapers under Windows\Web\Wallpapers included in the rotation, as well as any pictures that are in the same directory as your current wallpaper. It also directs you to the tray icon for further configuration. The default period is 30 minutes.

Once it's running, you can go back and forward in your "history" of wallpapers (only in the current-running instance -this data is not stored anywhere) using the menu on the Tray icon. You can also choose to never see the current picture again, pause on the current picture, change the time each picture is shown, and go to the next picture (forward if you've gone "back" in your history, otherwise, just advances to another random wallpaper ahead of schedule. You can also open up a GUI that offers slightly more complex controls - adding folders to the rotation (no, this doesn't get pictures out of subfolders, sorry) and browsing for specific pictures to exclude from rotation. All changes take place immediately.

By the way, decimal minutes work in the timing dialog - set it to .01 and get ready to have a seizure! ;-)

Let me know what you think!

edit: code revised to fix issue of .jpg files not working in less than Windows Vista - now XP and below only adds .bmp files to rotation (note there's only one .bmp file in a 'vanilla' XP installation in Windows\Web\Wallpaper, so be sure to add other directories as well). Also fixed the bug of erroring out of the program when all paths are deleted from the list of directories to include in the rotation. Thanks, Dethredic and AutoItR.

@Diveboy: thanks, I'm going to try your code and see if I can allow XP back into the code for including .jpg files, but I think it may be more than just refreshing the desktop that's the issue.

The wallpapers don't change for me

Time to start troubleshooting, huh? Dang, thought I might have one that worked first time :-)

What OS are you using?

What folder is your pre-existing wallpaper in?

When you go to Add/Remove pictures from rotation in the tray icon, what directories are listed on the left side?

This will help me get this nailed down.

Thanks

[james3mg]

Try only picking folders with only .bmp files in them - I noticed on another of ezzetabi's posts referencing this function that ".jpg wallpapers can only be set with Active Desktop" and this dll doesn't work with Active Desktop. Seems like they've fixed that for Vista though, since it's working fine for me.

Let me know if it works with .bmp files under XP.

Thanks for your feedback/patience :">

[james3mg]

I tried it on one XP machine I had access to with some folders with only .bmp files, and it seemed to work fine, unlike with .jpg files. Can anyone else (esp. Dethredic) confirm that? If that seems to be consistent, I'll build in a "If @osversion = Win_95 or Win_98 or Win_ME or Win_NT4 or Win_2000 or Win_XP or Win_2003" exclusion for listing the .jpg files, so that Vista and anything else that ever comes out will include the .jpg files.

Unless someone knows a call for assigning a .jpg as the desktop and refreshing it so it shows up...?

Thanks

[diveboy]

not really the clean answer your looking for, but we use this in a vbscript for bginfo pushed out via gpo.

c:\windows\system32\RunDll32.exe USER32.DLL,UpdatePerUserSystemParameters ,1 ,True

this will refreash the desktop when called.

[AutoItR]

it gives me an error when i try to remove a folder from rotation! otherwise the script is very good

Thanks!

Replace your code with the newly-modified code in the first post to get rid of the error! Are you running XP or Vista?
