PRB:Open Dialog Box Appears After Clicking Next in Wizard Form

• Microsoft Visual FoxPro for Windows, version 3.0, 5.0

SYMPTOMS

As you run a form that was created by using the Form Wizard, the Open dialog box appears when you click a navigation button such as the Next button. If the table used in the form is selected, a "File is in use" error appears. This occurs if SET COMPATIBLE is set to DB4.

WORKAROUND

Choose any of the following three workarounds.

Workaround One

This workaround sets the default Compatibility of Visual FoxPro to OFF.

1. On the Tools menu, click Options.

2. Click the General tab.

3. Clear the dBASE Compatibility check box.

Workaround Two

This workaround sets the Compatibility OFF until Visual PoxPro is restarted. In a program or in the Command window, issue the following line of code:

   SET COMPATIBLE OFF

Workaround Three

This is a permanent solution. Wizard-created forms will function correctly regardless of the setting of SET COMPATIBILITY.

1. Open the txtbtns class of the Wizstyle.vcx class library file. (This library is in the Wizards directory of Visual FoxPro.)

2. In the Initvars procedure, change the following existing line of code:

         THIS.nWorkarea = SELECT()
   

   to the following new line of code:

         THIS.nWorkarea = SELECT(0)
   

3. Save the class.

STATUS

Microsoft is researching this behavior and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

SET COMPATIBLE DB4 changes the behavior of the Initvars procedure. With the SET COMPATIBLE OFF setting, SELECT() returns the currently selected work area. However, with the SET COMPATIBLE DB4 setting, SELECT() returns the next available work area.

Steps to Reproduce Behavior

1. Create a new form by using the Form Wizard.

2. Issue a SET COMPATIBLE DB4 command.

3. Run the form.

4. Click the Next button.
