hi, I need text control .
That control must be that nobody can not enter any key from the keyboard and that i use my windows who i creates button to enter the keys.
And that keys from my windows when i enter must be visible for the user .
Staring key will be 0.
So i creating calculator like one in Windows XP .

That text control must have not any dialogs and it must be write in source file.
I am searching more like Richtext control but with extend style like i describe above.

Thank you for your effort of reading my post.
