Detect multiple monitors and set separate wallpapers for each

Question

I'm starting a project to make a wall paper rotator for computers with multiple monitors.

1) how do you detect the monitors in windows and the associated resolution

2) how would i set the image per monitor. do I make one image that's crafted together or do I set each one individually and how?

thanks

Answer 1

1. You can get information about all screens using the System.Windows.Forms.Screen class. Use their bounds properties to determine their layout.
2. Not possible on Windows (XP), you'll have to craft a big background image using the drawing routines in System.Drawing.
