How to bring up the Windows 8 on-screen keyboard in a desktop app

问题

I have a fullscreen DirectX desktop app, and would like to display the on-screen keyboard when the user taps a textbox in my game. Is there a way to do this while in fullscreen mode?

回答1:

Executing osk.exe will pop up the more old-fashioned on-screen keyboard. The Windows 8 touch keyboard will pop up by executing

C:\Program Files\Common Files\Microsoft Shared\ink\TabTip.exe

I just figured that out, since I'm working on a fullscreen desktop app that is running on a tablet PC without keyboard attached.

Same answer as Severin Stampler but in order to find the correct path from c# I use:

var path = Environment.GetFolderPath(Environment.SpecialFolder.CommonProgramFiles) + @"\Microsoft Shared\ink\TabTip.exe";

if (!File.Exists(path))
{
   // older windows versions
   path = Environment.GetFolderPath(Environment.SpecialFolder.System) + @"\osk.exe";
}
