It it possible to change the session language and keyboard language programmatically for current user via Windows API after the user has logged on? Changing some registry settings and logging off/rebooting is not a solution for me. I know that ActivateKeyboardLayout can be used to adjust keyboard but only works for the calling process. Thanks, Radu

not sure what language you program in, but take a look here: http://msdn.microsoft.com/en-us/library/ms724947(VS.85).aspx the input parameters include the relevant settings

I don;t believe that you can change the language after the user has logged in, as it requires logging out and back in to change the display. I believe that you can change the keyboard layout for an application with a call to ActivateKeyboardLayout, http://msdn.microsoft.com/en-us/library/ms645530(VS.85).aspx -- Mike Burr
