Problem 1. I've tried form.Activate. Here is what happens: Activated fires;
the txtBox.focus is executed; Entered fires and I set the backcolor to blue
and the forecolor to white; Leave fires and I set the colors back to
white/black. If I put a break point at the txtBox.focus command and step it
thru the focus is in txtBox with colors set blue/white (but wait the Leave
fired and the colors should be white/black). If I remove the breakpoint the
focus is not in the txtBox and the colors are white/black. There seems to be
a problem with one window becoming invisible and another becoming visible.
Maybe my 10ms timer lets things settle down. Any other suggestions?
Problem 2.
Tried your suggestions. Not any better than child.Dock = DockStyle.Fill and
doesn't position the window correctly (you still need to dock it or
something) and is still not maximized. Is there anyway of "clicking" the
restore box by code?
