VFP for the Non-Guru - Multiple Instances of a Form

by John Melton

It was quite exciting to hear in some of the promotional sessions concerning VFP how easy it would be to do various things that were, for all practical purposes, impossible in FoxPro for Windows. One in which I was particularly interested was multiple instances of the same form. In my zeal for VFP 3.0, I even made the mistake of promising this feature to a client before attempting to create it; it turned out to be more difficult than I originally envisioned.

Thinking I could simply issue DO FORM from a menu selection and it would execute the form as many times as a user wished was particularly naive. It turns out that certain properties must be set and additional code written to accomplish the task.

The following explanation assumes a typical structure in which an APP or .EXE is built with a main program (TestMain.PRG) calling a menu (.MPR) from which a user chooses among various options. In order to enable multiple instances of a form (TestForm), the user choice calls a program (TestPRG.PRG) which in turn calls the form (TestForm) which would typically be bound to a table in a database.

1. First, an array is created in the main program (TestMain) to hold variables for the NAME option when the form is called (see #3 below). The syntax is DIMENSION TstArray(1). TstArray(1) does not need to be given a value.

2. An appropriate menu choice is created for the user. The syntax for the command called by the menu choice is DO TestPRG.

3. The .PRG (TestPRG) which is called from the user menu choice contains the following syntax:
