FIX: DBGETPROP() of Offline Property May Incorrectly Return .T.

• Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a

SYMPTOMS

Attempt to take a view offline with the CREATEOFFLINE() function using a tablename specified in the CREATEOFFLINE() cPath parameter that already exists and select No in the dialog box that prompts you to overwrite the existing file. The CREATEOFFLINE() returns .F. as expected, and the view is not taken offline. When you use DBGETPROP() to check the view's Offline property, the return value is .T., incorrectly indicating the view is offline.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug has been corrected in Visual FoxPro 6.0.

Steps to Reproduce Behavior

1. Run the following code from a program (.prg) file:

   
         * Make sure you run this from a directory that contains no Testtab1
         * table or Testdb database files that you wish to preserve because
         * they will be overwritten.
   
         LOCAL lcTempFile
         SET SAFETY OFF
         CLEAR
         CLOSE DATABASE ALL
   
         * Make a Database.
         CREATE DATABASE testdb
   
         * Add a table.
         CREATE TABLE testtab1 (F1 C(10) NOT NULL ;
            PRIMARY KEY, ;
            F2 C(10) NOT NULL)
   
         * Get the temp directory and concatenate the file name.
         lcTempFile = GETENV('temp')+'\xxx.dbf'
         SET RESOURCE OFF
         COPY FILE (SYS(2005)) TO (lcTempFile)
         SET RESOURCE ON
   
         * Create view.
         CREATE VIEW lvTestview AS SELECT * FROM testtab1
         SET SAFETY ON
   
         * Attempt to take view offline, but select No in the dialog box.
         * This returns .F. as expected.
         ?"CreateOffline returns ", CREATEOFFLINE('lvTestview', lcTempFile)
   
         * Check to see if view is offline. DBGETPROP returns .T., but should
         * return .F.
         ?"DBGetprop 'Offline' returns ", DBGETPROP('lvTestview', 'View', ;
          'Offline')
   
         * Clean up temp file.
         DELETE FILE (lcTempFile)
         CLOSE DATABASE ALL 




2. Select No when prompted to overwrite the existing file.
