hi
i have an app in which i can drop objects onto a form and move them, it
consists of graphics (lines), i am using double buffering to avoid
filckering in the parent control which is a panel,but when i add
controls to this panel dyanamically, the double buffering effect is not
there, i move all lines connceted to a control when the control is
moved , at this time flickering occurs,also when i enable double
buffering for a child control an exception is thrown when i drop
control onto the panel
Double buffering does not carry through to child controls. You need to set
it for each control.
sayiong "Parameter is not valid." , at this line of code
Application.Run(new MainForm());
please help.
This usually happens when an exception is thrown in the paint event, you
need to track down that exception.
