BUG: SHOW WINDOW <name> REFRESH in BROWSE VALID Does Not Work

Article ID: 136557

APPLIES TO

This article was previously published under Q136557

SYMPTOMS

Using a BROWSE command that contains a VALID clause to refresh the browse upon changing the value in an indexed field does not work.

WORKAROUND

The user-defined function or procedure referenced in the VALID clause can force a refresh by following these steps in this order:

  1. Refresh the title of the window.
  2. Refresh the name of the window.
  3. Refresh the title of the window a second time.
To demonstrate this workaround, modify the 'freshen' procedure in the code listed in the "More Information" section of this article to this: 
   PROCEDURE freshen
      SHOW WINDOW customer REFRESH
      SHOW WINDOW vfpbrows REFRESH
      SHOW WINDOW customer REFRESH

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

Using the Customer.dbf table that ships with Visual FoxPro, create and run a program that contains this code: 
   USE C:\VFP\SAMPLES\DATA\customer.dbf
   SET ORDER TO TAG company
   DEFINE WINDOW vfpbrows FROM 0,0 TO 24,79
   MOVE WINDOW vfpbrows CENTER
   BROWSE FIELDS company :V=freshen(), contact WINDOW vfpbrows
   CLOSE ALL
   RELEASE WINDOW vfpbrows

   PROCEDURE freshen
      SHOW WINDOW customer REFRESH
With this code, you'd expect that making a change to the Company field would cause the record to assume its new position in the index upon exiting that field. However, that occurs only when a change is made to the first record in the file.

NOTE: In this code, the title of a browse takes on the name of the table that is being browsed. If a title is applied with a title clause in the DEFINE WINDOW line, then that title should be referenced in the SHOW WINDOW line of the 'freshen' procedure.
