Hi,

I'm using dotNet 3.5 winforms.

How do i detect when windows shift focus away from my application ??
I think it should be something similar to Application.OnLeave, but i can't
find it !

First I wanted to suggest to add a message filter by calling
Application.AddMessageFilter. However, this method doesn't seem to
handle all messages. I do not yet know why. However, you can override
a Form's WndProc method and handle the message (WM_ACTIVATEAPP=0x1C).
 
Hi Peter,

Are you looking for the Form.Deactivate event?

.aspx

This event occurs when the form loses focus and is no longer the active
form.

Best regards,

Hi Jie,

Nope, not form deactivating, but application deactivating :-)
I think Armin got it right talking ablout "WM_ACTIVATEAPP".
