Drawing on screen

[Hai Ly Hoang]

Hi,
I want to draw directly on to the screen. I think i should get the Graphics
object of the screen. It's easy to get do it in C++ (by GetWindowDC(NULL)).
But how to do that in C# ?

Thanks

Graphics g= Graphics.FromHwnd(this.Handle);

You can download a working gdi+ application here:

Hi,

You need to use GDI+

I have staterted my own beginners guide to GDI+ at
http://www.publicjoe.f9.co.uk/csharp/csharp21.html which talks through doing
this.

I also have a few articles aimed at beginners on my articles page found at
http://www.publicjoe.f9.co.uk/csharp/articles/articles.html

Also check out the chapters in my ebook page (link below)

Hope this helps
