The information in this article applies to:

Microsoft Word 97 for Windows

SUMMARY

When you write a Microsoft Visual Basic for Applications procedure, you may need to know whether or not the insertion point is positioned within an empty document or a blank document line. The sample procedures in this article determine whether the current line or document is empty and then display a message regarding the current status.

The following Visual Basic for Applications Sub procedure uses the predefined bookmark, "\Line," in combination with the Empty function to determine whether the current line is empty. Using this method will detect text as well as inline objects (such as an inline graphic) or floating objects anchored to the current line (such as a text box or drawing object).


   Sub IsLineEmpty()

      If ActiveDocument.Bookmarks("\Line").Empty Then
         MsgBox "The current line is empty."
      Else
         MsgBox "The current line is not empty."
      End If

   End Sub

The following Visual Basic for Applications Sub and Function procedures use the StoryRanges property to loop through the StoryRanges collection of the active document. Using this method will detect text as well as inline objects (such as an inline graphic) or floating objects anchored to the current line (such as a text box or drawing object).


     Sub YourMacro()

      ' Call the IsDocEmpty function.
      If IsDocEmpty() Then
         MsgBox "The document is empty."
      Else
         MsgBox "The document contains text, objects or empty lines."
      End If

   End Sub

   Function IsDocEmpty() As Boolean

      ' Initialize function to True.
      IsDocEmpty = True
      For Each astory In ActiveDocument.StoryRanges

         ' Check for text. If the length of the
         ' current story is greater than one, then
         ' there is either text or more than one
         ' empty line.
         If Len(astory.Text) > 1 Then
            IsDocEmpty = False
         End If

         ' Check for Objects.
         ' Note: If there are no objects within
         ' the current story range, an error occurs.
         On Error Resume Next
         If astory.ShapeRange.Count > 0 Then
            If Err = 0 Then
               IsDocEmpty = False
            Else
               On Error GoTo 0
            End If
         End If

         ' If something was found, then
         ' return to the calling routine with
         ' a value of False.
         If IsDocEmpty = False Then Exit Function

      Next

   End Function
