Hi,

You can find some examples here.

And here.

Those are good examples and there are many out there - especially if you name the object you want to use in your search. As for keeping the things you draw, you must provide a collection of that and iterate it in the paint event. I use custom objects and a List(Of <thatobject>) for this purpose. The pain event wipes the slate clean every time it is called - why you see the lines disappear with minimaize(causes the paint event to fire).

Thanks For The Posting Brothers. I dont want to draw automatically from within code, I want to use my mouse events and draw the shapes as if am picking a button from toolbox and drawing it on the form

So if you want to only draw them in the mouseevents they will not persist. A variable or collection is the only way to make it persist and this occurs when we repaint(refresh/invalidate the region/control). If you only need 1 object then a variable will do, you can make a boolean for when to show or hide it.
