Back key on the home screen can't take me back to my app.

Hi, there,

After I open/load my app, I go to the home screen. Then, when I press the
back key on the home screen trying to come back to my app, I just can't. Do I
miss anything in my app? Please help.

how do you 'go to the homescreen'?

Do you have code in your WM_ACTIVATE message handler to bring your window to
the foreground?

as neil has pointed out, what are you doing with WM_ACTIVATE?
trying either logging this windows message or break pointing it in the
debugger. The OS simply does SetWindowForeground() on your app, which
should send WM_ACTIVATE to your app.

Yes, I do have code in WM_ACTIVATE. I have a dialog. WM_ACTIVATE is handled
inside of the dialog proc. Basically, I set the focus to a control in
WM_ACTIVATE.

Yeah, but do you set focus to your application too? I'm pretty sure there's
some code you need (I don't know it off the top of my head) to do this as
well. Just setting focus to a control won't be enough.
