Hi everyone !
For those who haven't read my previous post, I have a problem with a
UserControl. When I try to display it on a form, controls seem to
appear one after one. In the following example, it's less visible
because controls don't execute any code... Is someone has an idea of
how I could solve this problem and also improve the method
ShowUserControl . I try to figure out I could flicker effect when I
press the button twice quickly.
Thanks for your help !
