I wnat to prevent the Focus Change (to get the KeyDown Event) by stroking the Tab Key. When My UserControl is laying alone on a Form I`m able to catch the
UserControl_KeyDown Event even with the Tab Key, but
if there an other Control on the Form which the property
"TabStop" is set on true, the KeyDown Evnent isn`t Raised.
I also tried to Get the WM_KEYDOWN Window Message (0x100)
with using SetWindowLong on my own WindpwProc, but i cant get the Message in that cases i wrote above.
