code for Printing the Prescription in C# Windows Form

This is a trial to print a Prescription using three controls: PrintPreviewDialog control, PrintDocument control and PrintDialog control.

My Project has one form (Form1) and two classes (clsReport and Globals).

Form1: has three text boxes for entering the data of the patient, the patient number and visit date.

Another three text boxes for entering the medication.

Three controls for printing: PrintPreviewDialog, PrintDocument and PrintDialog.

clsReport: has procedures for printing.

Globals: for some variables.

clsReport has the following three procedures:

Please read the code of Form1 then run the program to see the result. 

If you have any idea or if you find any problems then please tell me.
