Escape character ?

[Guest]

Hi, I post again a topic for which I never had an answer.

I'm developing an application that will run on PPC and on WinCE devices.
For this last situation I would like to close the current dialog box if the
user press the ESC button, but the KeyPress, KeyDown, KeyUp events are not
called when I press this button.

I've tried to see what happens in a textbox when I press ESC button:
nothing, no events are raised.

Why ? How can I solve this problem ?

Thank you in advance.

Use IMessageFilter [1] together with ApplicationEx to trap WM_KEYDOWN
window messages. Here is an example how to trap WM_KEYDOWN for Up/Down
keys for a TextBox [2]. The same technique applies in your case.
