Detecting hardware keyboards on Pocket PC 2003 Second Edition devices

  • Artikkeli

While I was at TechEd someone asked me how you detect a hardware keyboard on Pocket PC 2003 Second Edition devices. This could either be a clip-on keyboard or an integrated keyboard, depending on the device. Typically if the keyboard is attached you'll want to suppress displaying the on-screen SIP.

To detect the keyboard check the following registry key: HKCU\Software\Microsoft\Shell\HasKeyboard. This will be set to 1 if the keyboard is present.

    So, GetKeyboardStatus() isn't reliable, then?

    Don't know, I can ask on Tuesday. When I checked with our Shell developers though this is how they said to check.

    GetKeyboardStatus() doesn't report changes in added/removed keyboards. It only covers whether built-in keyboards are enabled. We'd like to fix that going forward, but for now the reliable way is to check the registry entry.

    Is there any better solution in CF 2.0 (WM 5.0) to detect hardware keyboard and detects events when it is enabled?

    Neil, A suggestion: there should be another value (or simply have HasKeyboard be '2') for devices with both a keypad on the front, and with a slideout keyboard; effectively this would mean that "it has a keyboard only when in the landscape orientation". This would be helpful on the upcoming Vox device and other PPC PE devices that have a keypad and a keyboard.
