Handling Keyboard Strokes
Keyboard strokes can also be handled by an add-in for DOKuStar Validation. The appropriate service is called
Keyboard service. First you must provide the keyboard service of Validation.
The keyboard service has two functions OnChar() and OnKeyDown() . In OnChar() you get the final code
from the keyboard. That means if you press Shift-A , you get the final key code in OnChar() , in this case 65 . In
OnKeyDown() you get the code for Shift and a . Normally you would implement hotkeys in OnKeyDown() .
For our example we assume that numbers should be suppressed in the edit control and that the user should get a
message box if he presses
F4 .
