Getmessage question

I understand the %WM_KEY,%WM_KEYDOWN,%WM_CHAR are messages that can be trapped here for the control with input focus, but I was wondering what other messages or what other ways of structuring this message loop people have found useful.

I never trap messages in the message loop; I trap them at the destination window.

If you want a 'system wide' or even a 'thread' thing, you can look at hooks.

I don't avoid this for any technical reason, I do it for maitenance purposes: the message loop is the message loop is the message loop.

In your case (" the %WM_KEY,%WM_KEYDOWN,%WM_CHAR are messages that can be trapped here for the control with input focus"), "subclassing" is the LED which turns on when I need to do this.

YMMV.

Bob,

Check this out in the source code forum.

I wrote a quick app that allows you to see what messages are being sent through the message loop versus to the dialog procedure directly.

I concur with the point of leaving it alone (the message loop), unless you have some funky special-needs app.

There are a multitude of methods to obtain keystrokes: a few are subclassing, superclassing, using a custom control, or keyboard accelerators (see ACCEL in PB help).

Thanks, Chris for the example.
