How to Trap for "Not a Database" Error in a Corrupt .DBC (128078)

MORE INFORMATION

To demonstrate, perform the following steps:

1. Create a new database and call it DATA1.DBC
2. In the Database Designer, right-click and choose New Table. Create a new table with the following fields:

         Field  Type       Width
         -----------------------
   
         Test1  character  10
         Test2  character  10
   						

   When prompted to Input Data Records Now, choose Yes and add data to the table.
3. Issue the following commands in the Command Window:

         CLOSE ALL
         USE c:\vfp\data1.dbc &&actual path to your .DBC file may be different
         BROWSE

CAUTION: If you are using an existing file instead of the example file created here, please back it up before proceeding to the next step.

1. Change the PARENTID in the first record to 0, then Save and Close the table.
2. Type the following into a program and run it:

         ON ERROR DO errhand         && To trap, and send to the error
                                     && handler procedure
         OPEN DATABASE SYS(2004)+'data1.dbc'  && An existing corrupt DBC file
         ON ERROR                       && To reset ON ERROR to default
   
         PROCEDURE errhand              && The error handler
         IF ERROR()=1552                  && Check which error occurred
           WAIT WINDOW 'Error #: '+STR(ERROR())+'  Message: '+MESSAGE()
         ENDIF

The error message "Error #1552 Message:File C:\VFP\DATA1.DBC is not a database." should be displayed in a Wait window.
