In which cases SetForegroundWindow return false

[C# Programming]

Hi,

I need to know when SetForegroundWindow return false because i try to set a form to the front using this code :

form.TopMost = true;
form.BringToFront();
bool focused = SetForegroundWindow(form.Handle);
if (!focused)
SwitchToThisWindow(form.Handle, true);
form.TopMost = false;

the form is showen but without having the focus.


best regards.

Keep it simple, stupid!
