Hello

I'm having a form that acts as some kind of OSD layer on top of the current
active window, however when I alt tab or click it, the focus can still be
given to that form. I don't want to happen.

I've been experimenting with the focus / enter / validating events, but I
don't seem to get it working.

Can someone help me ?

Thanks in advance,

Beren.

Did you ensure that the "ShowInTaskbar" property is false?

Yes I have set the property to false, but alt tabbing still shows the form
icon in the list.

Set the form border style to ToolWindow. That should fix it.

Thinking about your requirements a bit more deeply it seems to me that you
probably need a different sort of window entirely.

Consider making the window based on NativeWindow and using p/invoke to show
the window with the SW_NOACTIVATE style.

Hmm as you might have noticed I'm not that experienced yet...
If I make a new form class inheriting from nativewindow, how could I use the
invoke and that window message ?

Thanks for helping this clueless person

ps. the toolwindow setting solved the alt-tab issue, but then I had the
titlebar and borders ofcourse...

Set Form.Text = "" and Form.ControlBox = False to remove the title bar. You
still will have a small border around the form, but maybe this is OK for
you.
