The AltGr key is only on european keyboards and it creates the codes of Ctrl + Alt. You can easily test this, to get the characters @, {, }, [, ], or the Euro sign on most european keybords you usually press AltGr together with the appropriate key. But you'll get those characters by pressing Ctrl + Alt, too. HTH. Helmut.

From: Boris Pauljev on 29 Apr 2010 14:47 In a Turkish Windows, I ran the code, and for "i" (it's the same on the Turkish keyboard as the ASCII "i", among other Turkish which also correspond to ASCII characters), it returned 1605. It's driving me crazy. I wanted to say that "a" also exists on a Turkish keyboard and an English keyboard, and in my tests, they were the same. They produced normal results, not AltGr indicators. All keys are perfectly fine and what I would have awaited, only "i" is giving this strange value, indicating that AltGr should be pressed, which is definitively wrong. Any ideas what might cause this behaviour?

I guess this has to do with VB KeyCodes are only valid for a US keyboard + some more. All international keys can't fit into the "extended" 256 char ASCII. You may just have to accept that the Turkish Unicode "i" is represented as Ctrl-Alt i. I guess other "special" Turkish keys will produce the same "errors". You for example have 4 different "i"'s. A look-up table can solve the issue. /Henning |
