The information in this article applies to:
SUMMARYWhen 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.

http://www.microsoft.com/support/supportnet/refguide/default.aspThe 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 SubFor more information about predefined bookmarks, click the Office Assistant while in the Visual Basic Editor, type "Predefined Bookmarks," click Search, and then click to view "Predefined Bookmarks." NOTE: If the Assistant is hidden, click the Office Assistant button on the Standard toolbar.

ARTICLE-ID: Q179216 TITLE : OFF98: How to Use the Microsoft Office Installer ProgramThe 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 FunctionFor more information about the StoryRanges property, click the Office Assistant while in the Visual Basic Editor, type "StoryRanges Property," click Search, and then click to view "StoryRanges Property."
