Dear gurus,
A simple (I hope) problem: how do you respond to keypresses such as Ctrl+A under the Wimp? Simple printable character codes are fine, and there is a table in the PRMs for special key combinations like Ctrl+F3, but I can't immediately see how you handle 'altered' printable characters.
Apologies if I've missed something very obvious, but grateful for any help. |

How are you checking for it? In a writable icon, or in general use - e.g. like Menon, which will respond to CTRL-A by loading ArtWorks for me if nothing else claims that key combo at the time?

 Cheers,

In general use. My app has a menu option to create a new record, which I also want to happen when Ctrl+N is pressed when the window has the input focus. |

So it's only when you have the window focus? OK... I'm using INKEY commands (in BASIC, obviously), but that's for actually opening windows of a program that doesn't have input focus 
If you have input focus, doesn't that mean you *are* doing this in text input boxes (mostly)? It might be worth changing the validation strings of your inputs so that they use Ktarn rather than the usual Ktar - that way, notificiations of all key presses are passed to the program. Then you should see more being passed on in wimp poll (eight) messages.
Or an actual programmer can chip in...?

Sorry - I'm not being clear at all...
<rephrase>
I've got no problem intercepting the keypress: my problem is I don't know what character code to check for. If someone presses Return, I can check for character code 13. If someone presses Ctrl+F3, there's a list of character codes in the PRM. But I don't know what code to check for if someone presses Ctrl+N: I assume it's ASC("N" ) plus something.
</rephrase>
Thanks for the tip on Ktarn, though - I'd forgotten about that and it will be useful (for another reason, however ). |

OIC - CTRL-A = 1 CTRL-B = 2 etc? They're standard ASCII characters.
(Of course, I didn't actually remember that until I'd modified one of my programs to report what was being passed on by wimp polls  )

Or simply (in C):
switch(code) {
case 'A' - 64 :
// Ctrl-A
//...
}
Other languages would be similar (it's been a long time since I've done BASIC. Could be ASC("A" ) - 64... |

Ctrl-N is &E according to the WimpKeys Stronghelp manual. |

Hmm. I should have thought of that (reporting back what the Wimp Poll was broadcasting, that is). So much for being proactive!
But thanks - that's really helpful. I think I'm finally getting nearer a release date...  |
