Hi,

I'm looking for a way to let users create images online.
As my whole web application is done in ASP.NET I don't like to use FLASH or JAVA for.
Is there a way to make a small paint app with ASP.NET or are there some third party modules available?

Thanks,

Andre

What about GDI+ ? it is not a Flash nor a Java :)

Draw is a draw every where in .NET
If you drawing in C#, ASP, VB, Java  You will use the same packages

Yes I agree is not Flash or Java.
I think to draw something on the screen is not the problem - but I don't understand how this sample can help me to let the user paint an image online?

It won't.  You cannot use GDI+ like this, unless you want to send the drawing information (like vector graphic information) to the server and have it render it.

You have to use a program like Flash, Java, or Silverlight (which is .NET).  ASP.net will only send HTML documents to the browser, and there is nothing in HTML which would let you do this.  JavaScript is the closest thing, and it doesn't do graphics well.
