WD: Macro Function to Test for Valid Directory Path

• Microsoft Word for Windows, versions 2.0, 2.0a, 2.0a-CD, 2.0b, 2.0c, 6.0, 6.0a, 6.0c
• Microsoft Word for Windows 95, versions 7.0, 7.0a
• Microsoft Word 97 for Windows
• Word for the Macintosh, versions 6.0, 6.0.1, 6.0.1a
• Microsoft Word 98 Macintosh Edition

SYMPTOMS

If you create a macro that attempts to change to an invalid directory path, you may receive either of the following error messages:

   Run-time error '76': "Path not found"

    -or-

   Wordbasic error 76: "Path not found"

CAUSE

Before you switch to a directory using the Microsoft WordBasic or Visual Basic for Applications ChDir statement, ensure that the directory is valid.

WORKAROUND

Create macro code to test whether a directory path is valid.

Word 6.x, 7.x:

   Sub MAIN
      If CountDirectories("<Replace with a valid directory path>") \
      > - 1 Then
         MsgBox "Directory is valid"
      Else
         MsgBox "Directory is not valid"
      End If
   End Sub

Word 2.0:

   Sub MAIN
      On Error Goto errorhandle
      ChDir "<Replace with a valid directory path>"
   errorhandle: ' NOTE: This line must be left aligned.
      If err = 76 Then
         MsgBox "Directory is not valid"
      Else
         MsgBox "Directory is valid"
      End If
   End Sub

NOTE: Macintosh users, the above macro examples contain Windows path information. Be sure to use a valid Macintosh path. For example:

   ChDir "Mac HD:Microsoft Word 6"
