>BINDEVENT( ) does not directly support the Value property because it is handled by Visual FoxPro in a special way. You should use the InteractiveChange and ProgrammaticChange events instead. Additionally, the ActivePage property is not supported.

Add ActiveControl,ActiveForm and many others to the unsupported list.
