Intercept the *Return Key*
Posted: Wed Feb 01, 2012 11:37 am
Why is this always an ever changing *workaround* problem?
Press the return key and go do something << thats all I'm asking for
Am I the only one that uses the enter key?
Or should I say, am I the only one that uses the enter key wrong?
Seems to me being able to detect the enter key, return key (whatever you want to call it) should be easy as falling off a rock.
I have 24,000+ lines of code and almost every time there is a version change and I upgrade, I find something changed in the way the return key is handled. Every time that happens I spend weeks trying to sort out where my code is broken and ultimately comes back to half dozen goofy code girations I've had to apply to try to detect use of the retun key.
Now, again, plain as day I see this in the v4.60 help and I think:
FINALLY ... I FOUND DOCUMENTED SOLUTION!!!! 
^ ^ ^ it says right there -- If EventType() = #PB_EventType_ReturnKey ^ ^ ^
... But, even that does nothing. Nothing mentioned in the PBv4.60 Help/History about ''PB_EventType_ReturnKey''.
I think I have tried every possible *workaround* solution. Everything from AddKeyboardShortcut(), callbacks and Windows API. Somebody must know a cast iron rock solid cross platform proper method of detecting use of the return key -- that is not a workaround. Fred? Fr34k? Somebodyyyyyy?
Code snippet above came from PBv4.60 Help -- sample code: 'Gadget.pb'
