PRB: Setting PageOrder May Generate an Error

• Microsoft Visual FoxPro for Windows, versions 3.0 and 3.0b

SYMPTOMS

Changing the PageOrder property of a page to a value higher than the PageCount property will trigger the error "Expression evaluated to an illegal value."

WORKAROUND

The PageOrder property should not be greater than the value of the pageframe's PageCount property.

STATUS

Microsoft is researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Steps to Reproduce Behavior

1. Create a new form.

2. Add a pageframe to the form.

3. Set the PageCount property of the pageframe to 0.

4. Create a new program file that contains the following code:
