On a tablet computer running Windows XP Tablet Edition, Vista or Windows 7 -- setting focus on a textbox triggers a small keyboard popup icon to be shown (unless the user already has the on-screen keyboard open or docked). In my application I've implemented my own on-screen keypad for certain fields and I want to disable the Windows on-screen keyboard popup for those textboxes.
Is there a way to disable the on-screen keyboard popup icon for specific textboxes in an application?
