Hi,
I need to develop a user control which displays some rectangles and
polygons. To draw something like this seems to be easy but I need the
functionality that the user can click on some lines to select these
lines of a polygon them. Is there a framework available like eclipse
GEF or JGraph in Java.
Thanks for every hint

Thanks for the answer. That sounds good. I have just one more problem.
I am using
e.Graphics.Scal eTransform(scal eFactor, scaleFactor);
to scale my picture. Is it possible to overgive this factor in some
way?

Hello all,
I was wondering... Is there a way to create a Array so that I can call a
value with a name i.s.o. a index number? Something similar like a DataTable.
This is what I want: Declare a array of some sorts, private string test;

I don't want to get the value by saying: test but test
Can this only be done with a DataTable? But DataTables are for databases
