[02/03] Supressing Alt-[letter key] 'Ping'

In the second part of our quest for a way to implement application hotkeys we've hit another snag, the mnemonic 'ping' that happens when you press Alt-[letter key] when there is no matching mnemonic control. (See the earlier post for more details on what we want to do.)

The kind of kludgy workaround is to add a hidden matching label with the mnemonic character you want and play around with the tab order so that your target control doesn't lose focus when you hit the key combo. I suppose a menu item would also do this but the form in question is a modal dialog that doesn't have a menu.

Is there a way to turn off default mnemonic key processing on a form?

Any more elegant workaround suggestions?
