PRB: List Box for Logical Field Has Highlight at Bottom

• Microsoft FoxPro for Windows, versions 2.5, 2.5a, and 2.5b
• Microsoft FoxPro for MS-DOS, versions 2.0, 2.5, 2.5a, and 2.5b

SYMPTOMS

In the list box for a logical field, the highlight either appears at the bottom of the list or doesn't appear at all.

CAUSE

List boxes created from logical fields must have the variable initialized in the Screen Setup code, and it must be initialized to a character (usually an "F" or "T") other than " ". If the variable is set to " " or not set at all, the selection highlight either will appear at the bottom of the list or will not appear at all.

RESOLUTION

Initialize a variable for the logical field in the Screen Setup code and make sure you initialize the variable to a character. For example, if you initialize the list box variable as "T" in the Screen Setup code, the list box highlight will appear at the top of the list.
