Saving objects drawn on UserControl

Hi guys. I am trying to save 2D graphics shapes that were drawn on a UserControl. I mean, it is like Microsoft's paint application where the user can create different shapes like rectangles, lines and then save it to a file in their PC. They can later come to that file and open it.

I am currently drawing these shapes in a UserControl and wanted to save it as I explained above. I thought one way would be to serialize the UserControl. But some googling showed me that UserControls and WindowsForms are not suitable for serialization.
Is there a way around this thing? I appreciate any ideas you might suggest if you have an experience on this thing.

Thanks in advance

Do you want to save each drawn shape as a separate object, or just save everything drawn as an image?

I want to save what I have already drawn on to the UserControl as one object. But I want to do all the operations that I was able to do on the object before I saved it. i.e like changing the size of rectangle for example, changing its position and so on.

I would take a screenshot of the the window which hosts your user control. A sample code to do this you can find here :

Screenshot C# Example

The page is in german, but the code is quite self-explainatory.

Good luck !

Now that is quite a lousy solution to his problem, because he won't be able to open his images in any other tool but his own...
