Very nice ! You\'ve done a good job. I always loop up for all the new tutorials form you.
Such a wonderful page !
Keep going on...

this one doesn't work...
first of all i changed the code and tried other options to get it run, but it still doesn't work!
when i want to set the new wallpaper, my desktop wallpaper is always dark blue (i'm using windows xp service pack 2)
---
1 bug i detected is at the RegistryKey.SetValue method where you optional can put a RegistryKeyKind parameter
---
from other sources i found out that the API call looks like that:
SystemParametersInfo(20, 1, WallpaperLocation, 0x2);

but that even didn't help -.-
---
before that i sometimes have dealt with unmanaged functions... that always went good...

The code has only been tested with Windows Vista. It works with Windows 2000, 2003 and XP as well, but only with Windows Bitmap files (BMP). It won't work with PNG, JPEG, GIF, etc. as it does on Windows Vista. I'm adding this information to the tutorial.

rrrrrrright... with BMP files it works now ;)

Hi, it is possible to set an hmtl desktop using this code?

Sir,

I want to learn C++ online and want to be capable of creating programs for graphics.

how should i proceed to be effective in my goals

in XP, there was a 1 liner using user32.dll to refresh the wallpaper after a change to the registry...is that possible in vista?

when i go to control panel then personalise to put backgound wallpaperon. the part that says backgound as disappered and the background is black at the moment how do i get it back on

This code does not retrieve the wallpaper for a solid color wallpaper. Where in the registry can I get the color of the wallpaper if it is a solid black, white, red, green, etc... since when solid colors are chosen, the wallpaper value is "" (blank). Please help...

Hi the process worked fine for me but when I try to make it into a windows service which triggers the event every 10 minutes The SystemParametersInfo(20,1, location, 2|1) returns 0 and the wallpaper doesnt change.

I tried using the local system environment and using the user environment.
Could you please help me sort it out.

hi!i just wanna know how can i set up my own wallpaper on my screen without anyone can discard or change it except me.can you help for this.

Hey, thanks for the tutorial. It taught me exaclty what i wanted to know.

I have modified your program into one that cycles through an array of images, changing the desktop image at user defined time intervals.

The problem i am having however is that only certain images work. I am using windows XP and yes, i am only using .bmp files. As i say, only some of the images work, ones that do not work simply turn the desktop a solid blue colour untill the next working image comes and replaces it.

Any help would be much appreciated. Thank you

You wouldn't believe how long it took to find a method in code to refresh the registry settings. Executing RunDLL32.exe (either from code or manually) just didn't do it.

Thanks very much! All I have to tie down now are the permissions issues with accessing unmanaged code through a remoted/WCF component...

Thanks for ur tutorial

Did anyone sort out how to get this to work from a Windows service? I have it working fine from a Forms application, but when I copy the same code into a service, the wallpaper isn't changed.

Anyone know? Thanks,
Yossu

Oops, right after posting I found the answer.

In case it helps anyone, you can't do this from a service! See this discussion for more details...

Bad code. You should use special Windows interfaces instead of manual editing the registry.

I'm in office right now, and here IT guys had disabled the function to change destop Background. So a user will not see the Desktop Tab whenever they right-click on Windows XP professional's desktop.

In this scenario another interesting thing for u is that they have altered the basic/default location of wallpaper as well as its filename also.

Which means that wallpaper will always be selected from dafault location of "C:\Documents and Settings\<current user>\Local Settings\Application Data\Microsoft" and its filename should be "wallpaper.bmp" only.

In this situation... I would luv to make u think about a solution to change the wallpaper :)

I forgot to mention that I really liked the way this TuT had been written, its excellent.

When I logout... the desktop background is changed, means it had worked. But the current user's background id still not changed.

Whenever the user will login back into the network... the current user's background will be reset back to what had been done my IT fellars.

Now u may please proceed to test :)

Good tutorial to learn new thing.Continued the good work.

Thanks,

The data type of the WallpaperStyle and TileWallpaper should be string. If they are saved to the registry as int [or any other number format] it does not work.

Here's my modification of the code which works for me:
____________________________________________
private void btnSet_Click(object sender, EventArgs e)
{
if (openGraphic.ShowDialog() == DialogResult.OK)
{
// Preview the wallpaper in a PictureBox
picThumbnail.ImageLocation = openGraphic.FileName;
// Fit the PictureBox
picThumbnail.SizeMode = PictureBoxSizeMode.Zoom;
//determine the option the user has selected
string tileStyle = "0";
string wallStyle = "0";
switch (ddlStyle.SelectedIndex)
{
case 0: //stretch
tileStyle = "0";
wallStyle = "2";
break;
case 1: //center
tileStyle = "0";
wallStyle = "0";
break;
default:
tileStyle = "1";
wallStyle = "0";
break;
}
// Pass the file path, and two options to specify the wallpaper style
SetWallpaper(openGraphic.FileName, wallStyle, tileStyle);
}
}

private void SetWallpaper(string WallpaperLocation, string WallpaperStyle, string TileWallpaper)
{
// Set the wallpaper style to streched (can be changed to tile, center, maintain aspect ratio, etc.
RegistryKey rkWallPaper = Registry.CurrentUser.OpenSubKey("Control Panel\\Desktop", true);
//set the wallpaper's location
rkWallPaper.SetValue("Wallpaper", WallpaperLocation);
// Sets the wallpaper style (tile, center, stretch)
rkWallPaper.SetValue("WallpaperStyle", WallpaperStyle);
rkWallPaper.SetValue("TileWallpaper", TileWallpaper);
//close the registry key
rkWallPaper.Close();
// Have the computer update the wallpaper
SystemParametersInfo(20, 0, WallpaperLocation, 0x01 | 0x02);
}
