Control Properties
A program or form can refer to properties of another active form via a form variable . Encore RPG automatically declares a form variable globally with the name of the form for each form in the project. Thus, if you have a project that has 2 form programs, FORM1.vr and FORM2.vr, and the Name property of each form is FORM1 and FORM2 respectively, Encore RPG declares two global form variables with the names FORM1 and FORM2.
When a form becomes active via a SHOW operation, or by having it as the main program, its properties can be accessed and set from outside the form. This is done using the following format:
form.Property (or)
form.control.Property
Example
If FORM1 shows FORM2, it can also set properties in FORM2 by doing the following:
MOVE H”000000FF” Form2.BackColor
MOVE “Hello from Form1” Form2.IOField1.Text
