Not an easy going ...

1st you need to create a Method on the Form which provides the TouchKeyboard. This Method has to look if any of your Textboxes got the Focus. Perhaps it looks also if you need a special restriction to the TouchKeyboard (for example only numeric inputs).
2nd you create your TouchKeyboard - for example as a Dialog. This Dialog holds all the Buttons for the different needed characters which should be used. Each of this Buttons modifies the Text-Property of your Dialog (you need and you should not use SendKeys). If your input is finished your Text-Property holds the final Input.
3rd your Form-method opens the Dialog and because it knows which Control the Dialog requested it could also position the Dialog matching to the calling Control. When your Dialog has finished you only need to write it's Text-Property-Content to the calling Control.

Of course you could downvote my answer - it's your decision.
In fact this answer is the way you have to go - or let it be ...
If you want to go a step ahead you should realize that it isn't helpful to wait that someone does your work for you.
The real answer I could give to you is : start using Google ... and try to improve yourself ...
