wpf - Windows 8 Desktop App: Open tabtip.exe to secondary keyboard (for numeric textbox) -

We are working on an desktop WPF app that runs on the Windows 7 tablet and some Surface Pro units with Window 8 for mixing.

We immediately saw that when a text box receives focus, the small keyboard icon no longer displays. We have solved this by running "TabTap.exe" on mouseDown event for all textboxes.

We have some numeric text boxes (although the quantity for an item on the order), and for the numerical entry that you want to open the on-screen keyboard, but it opens by default with the qwerty key.

I am searching extensively for any command line arguments which I can run on tabtip.exe to change my input mode, but there is no luck. It looks like a trivial work with a metro-style app, but it is impossible on the desktop side.

Is there a command-line argument for tabatt.ax? Can I use it to accomplish this?

in HKEY_CURRENT_USER \ Software \ Microsoft \ TabletTip \ 1.7 (Windows 8) REG_DWORD is the standard layout value of 1 keyboard layout Code> Last UseDemovality Cardholder should also be 0 or 1 , if the tabt starts again, then this pen Writing will open from the area.
