SYMPTOMS
When a form is run with a DO FORM command, it appear to enter an infinite
loop, and you cannot release it. When the same form is modified with a
MODIFY FORM command, a Syntax Error is displayed. It is not possible to
open the form.
CAUSE
The value of a custom property has been incorrectly set to (); that is, the
value starts and ends with a parenthesis.
WORKAROUND
You can manually open the form (SCX table) by using a USE command. Browse
the SCX table, and edit the Properties memo field to remove the property
that is causing the error. Then close the SCX table, and compile the form
by using the COMPILE FORM <name> command. Once the cause of the error has
been removed, you can edit the form with a MODIFY FORM command.
NOTE: manually editing the SCX table should be performed as a last resort.
Use extreme caution when deleting data from the SCX table.
If you must set a default value of () for the property, place quotation
marks around the the expression in the property sheet.
STATUS
Microsoft has confirmed this to be a problem in the Microsoft products
listed at the beginning of this article. This problem has been fixed in
Visual FoxPro 5.0 for Windows.
When you attempt to modify the form in Visual FoxPro 5.0, the "Syntax
Error" message appears. However, the form opens.
