PRB: OptionButtons Do Not Hold Logical Values (245062)


The information in this article applies to:

  • Microsoft Visual FoxPro for Windows 5.0
  • Microsoft Visual FoxPro for Windows 5.0a
  • Microsoft Visual FoxPro for Windows 6.0
This article was previously published under Q245062

SYMPTOMS

In Visual FoxPro 5, it was possible to set OptionButtons to have logical values instead of numeric. However, in Visual FoxPro 6, this behavior changed. While the buttons can be set to logical values, clicking on a button will cause the button's value property to be reset to numeric.

CAUSE

OptionButtons should only have numeric values, even if the interface allows them to be set differently.

STATUS

This behavior is by design.
