ID: Q126955

3.00 WINDOWS kbtool kbprb

The information in this article applies to:

• Microsoft FoxPro for Windows, version 3.0

SYMPTOMS

When you build a PROJECT or APPLICATION in Visual FoxPro, you may get a warning box that says 'Unable to find unknown <array name>.'

CAUSE

One cause of this error is an array being used in a screen or other program.

RESOLUTION

This is only a compile time warning and will not prevent your application from building or executing correctly.

To prevent this warning from appearing In Visual FoxPro, put the EXTERNAL ARRAY command in the Load Event of the Form or FORMSET with a #REGION 1 before anything else, as in this example:

   #REGION 1
   EXTERNAL ARRAY <array name>

NOTE: Make sure you issue a READ EVENTS command after the DO FORM command or you will get the error "Variable not found" when executing the form.
