dzEventsMagic example
 Previous  
This is an example application using the dzEventMagic library that may be cut and pasted. It traps key messages and allows a label to be moved around a form with the arrow keys.

It requires a form named "Form1 to be created in the Form Designer and a Label control added. Place the label in the middle of the form.

It also requires a dzEventsMagic object named dzem to be created before running it.

Apologies for the small font. Helpmaker, used to create this helpfile, does strange things when changing and resizing fonts including removing colour. I thought it best to retain the familiar colour coding and tolerate the smaller font.
