SYMPTOMS

Running a Visual FoxPro formset results in the error "Feature Not Available" when a READ is executed in the Load event of a form.

CAUSE

A READ in the Load event of a form in a formset causes the error. However, if the form is not contained in a formset, the error doesn't occur.

WORKAROUND

There are several workarounds. The READ must be removed from the Load event of the form in order for the form to run in a formset. Here are some possible workarounds:

Place the READ in the Load event of the formset.
If the READ is being used to activate a window, perhaps a message box can be used as an alternative to the window.
Remove the formset.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Problem

Create a new form.
Within the Form Designer, on the Form menu, click Create Form Set.

Add the following code to the Load event of the form:

   DEFINE WINDOW confirm FROM 1,1 TO 10,10
   ACTIVATE WINDOW confirm
   x= " "
   @ 5,5 GET x
   READ
   RELEASE WINDOW confirm

Run the Form. The error "Feature Not Available" will occur. To resolve the issue, open the form in the Form Designer. Then on the Form menu, click Remove Form Set, and run the form.
