what i am trying to do basically is to draw a simple line
in a MDI Form between Children Forms ...

To draw a line on a normal form i use the following :

Graphics p1 = this.createGraphics ();
p1.drawLine (x1,y1,x2,y2);
And this works ...

i used it in an MDI Form ( This Pointing to a MDI container ) and no lines show ... and no errors ... any ideas ?
