Refreshing Desktop

[aewarnick]

I want to make a progam to change the Wallpaper but the desktop needs to refresh to work. How do I access the desktop to refresh it?

Nope. Thank you though.

Private Const SPI_SETDESKWALLPAPER As Integer = 20
Private Const SPIF_UPDATEINIFILE As Integer = &H1
SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, "C:\bitmap.bmp", SPIF_UPDATEINIFILE)

You will need to declare SystemParametersInfo first, of course.

I saw that online except it was more complicated:

public class User32dll
	{
		[DllImport("user32.dll", CharSet=CharSet.Auto)]
		public static  extern int SystemParametersInfo (int action , int param , string path , int hex) ;
	}

The call: (bmps is a string array of pictures)

User32dll.SystemParametersInfo(20, 0, bmps[tick], 0);

Instead of 0 they had 0x1 | 0x2 as the last param.

 

My question is, what does all of that mean? The 1st, 2nd and 4th param, that is.

An in-depth description of the SystemParametersInfo function can be found here:

That was useful and I bookmarked it but it never goes over what those arguments do.

Why not consult the documentation? MSDN?
