PRB: Double-click in File Manager Starts Wrong FoxPro Version

 Last reviewed: April 30, 1996

The information in this article applies to:
  • Microsoft Visual FoxPro for Windows, version 3.0

SYMPTOMS

When an .APP file is started from a program icon or by double-clicking in File Manager, Visual FoxPro is invoked instead of FoxPro for Windows and Visual FoxPro fails.

When a FoxPro version 2.x .APP file is invoked from Visual FoxPro, Visual FoxPro fails and displays this error message: 

   Object file "<Drive:\Pathname\file.app" was compiled in a
   previous version of FoxPro.
When you click OK, you remain in the Visual FoxPro interactive development environment.

CAUSE

When Visual FoxPro is installed, the .APP file extension is automatically associated with Visual FoxPro, not FoxPro for Windows.

WORKAROUND

Use any one of the following three possible solutions. The first applies to Windows NT, and the second and third apply to any Windows platform.

  • Using REGEDT32 in Windows NT, revise the software hive entry of HKEY_Local_Machine under Software, Classes, APP from the value of Visual.FoxPro.Application.3 to MSFoxPro. Be careful when using the Registry Editor.

    -or-

  • In the File Manager, select any FoxPro version 2.x .APP file. Then choose Associate from the File menu. In the Associate dialog box, associate the files with the .APP extension to Microsoft FoxPro for Windows. Click the OK button, and the registry will be automatically updated. Attempting to change the association in any other fashion causes a general protection (GP) fault in the File Manager.

    -or-

  • Revise your application icons to have a fully-qualified path that invokes your application. A sample command line for an application might be something like this:

    C:\FPW26\FOXPROW.EXE INVOICES.APP

STATUS

This behavior is by design.
