Hej!

Har sett att många program har en "hotkeybox" alltså en sån som Windows använder när man ska associera en hotkey för att starta ett program, går det att få något liknande i VB6?

Hej!

Visst kan man göra det. Du får använda dig av RegisterHotKey-API't

Koden nedan registrerar Ctrl-Alt-A som hotkey och ger dessutom din applikation fokus när hotkey-en triggas.
Mycket nöje! :)

'Ta bort hotkey

Varför inte subclass formuläret och fånga medelande där?

MS-Johan: Det var inte riktigt så jag tänkte utan jag ville ha den där textboxen som fångar upp vilka tangenter man vill ha till sin hotkey.
