P/Invoke assistance

[dmarolt]

I'm working on an application. This application has several fields which will only have numerical input (Zip code, phone number, part #, etc).

This application runs on Windows Mobile 5 & 6 with a touchscreen and full keyboard (So basically Treo's and HTC phones).

To type a number on these phones, you need to hold down a Function Key, then hit a letter which corresponds to a number. It has been requested to eliminate the need to hit that function key, and have it automatically input the number.

I cannot hard code this because it's certainly not very extensible (Well, I could hard code it, but whatever)

I was thinking I could P/Invoke "keybd_event" the Function key, and it should work from there.

However, I cannot find what key code the "Function" key is.

And also, will this key code be the same across all phones?


I suppose one last note, if you know a better way to achieve this without using P/Invoke, I'm up for new ideas

Thanks for your time,

Dan

I'm afraid I can't be of much help here, but you for sure *can't* get a Function key code. There isn't. It's deep in the keyboard driver.
However, according to this (http://blogs.msdn.com/windowsmobile/archive/2007/02/06/how-do-you-dial-1-800-flowers.aspx), there's some hook you can ask OS for to convert letters to numbers. But with MS, it might as well be hidden from public...

There has to be some message that's sent to the OS when I hit the Function Key, I just (obviously) don't have Spy++ on my PPC.

I was looking up a few things.

Is there anything relevant contained in keybddr.dll?
