FIX: Error in Converter: Variable Gendircount Not Found

The information in this article applies to:

• Microsoft Visual FoxPro for Windows, version 3.0

SYMPTOMS

When a screen built in FoxPro version 2.x that contains a #REGION statement is converted, the converter halts, and displays this error message:

   Variable 'GENDIRCOUNT' is not found

CAUSE

This is an error in the Converter. The error occurs when the #REGION statement is located in an object's code or in the Cleanup code - but not in the Setup code. This causes the GENDIRCOUNT variable to be passed to a method when it was not initialized.

WORKAROUND

Edit the Converter code to initialize the GENDIRCOUNT variable. The source code to the Converter application is included with the Professional Edition of Visual FoxPro. The following step-by-step procedure illustrates the method to correct the error.

Step-by-Step Workaround

1. Open the Convert.pjx project located in the Tools\Convert directory.

2. Select the Code tab. Drill down to view the Program, and select the Convert program. Click the Modify button to edit the file.

3. On the Edit menu, click Find, and in the Look For area of the dialog box, type FUNCTION AddMethods. Click Find. The Addmethods method is the one to modify.

4. The second line of code in the Addmethods method is this LOCAL statement:

         LOCAL cTmp, savearea, gendir, m.newmethod2
   

   Add the GENDIRCOUNT variable to this statement. It should now read:

         LOCAL cTmp, savearea, gendir, m.newmethod2, Gendircount
   

5. Close the Program, and save changes. Rebuild the Converter application.

6. In the Project Manager, click the Build button, and then click Build Application. The Save As dialog box is displayed.

7. In the Save As dialog box, select the main Visual FoxPro directory (VFP).

8. Click Save. The new application is built in your VFP directory.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in Visual FoxPro 3.0b for Windows.
