SUMMARY
When you write a Microsoft Visual Basic for Applications procedure, you may need to know whether 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.

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements.

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 detects 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 detects 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
