No...

And since you speak of "the character's ASCII code", it means that this special key of yours might just be a shortcut of another standard existing key. So, use that one instead.

tbh, very very doubtfull.

-------

What is the key and what is it supposed todo in Plus!?

The key is VK_OEM_4 (0xDB) on US keyboards, which is ASCII 91 (0x5B), or "[". It may not be parsed when it is typed as in the script, but it is used for tags within plus!, and many other projects, so it must be common to be on keyboards.

Why would using VkKeyScanW not work? I provide it with a static ASCII code which never changes (91, or 0x5B) and it provides me with its virtual key code (in my case, VK_OEM_4 or 0xDB). It's then compared to the pressed key code so it should work on all systems that have "[" as one of the keys...

I do not think it's a "shortcut" for another existing key, because MSDN labels only VK_OEM_4 as "[", and the ChatWndEditKeyDown function provides a virtual key code and not an ASCII one...

It actually isn't. Also ToAscii also requires a scan code, which isn't provided by Plus!.

It is not because the character [ is used as part of formatting tags, that Plus! detects it as a virtual key. Plus! parses the string you already typed and checks the ascii codes (which can be different than virtual codes). As I know you know... :p

That character/key can be 0xDD on other keyboards for example, also you must to take into account the shift states which Plus! doesn't all support either, so:

It wont unfortunatly, because it is an OEM key.

Ps: And on Belgium keyboard pressing "[" will not even trigger a ChatWndEditKeyDown as it involves pressing AltGr (=right ALT) which is not detected by Plus! either.

Not to mention that the API VkKeyScan is something left over from Win95 and since then much things have changed (while the API has not). It wont work ligatures, dead keys, SGCAPS, or anything on the numeric keypad. And the biggest problem is it does not distinguish between the left and the right SHIFT/CTRL/ALT keys, which would be needed to specifically define the proper key. The API VkKeyScan is virtually (get it? 'virtually' :D:p) useless and shouldn't be used....
