A sample macro (Sub procedure) named Driver is also included to demonstrate how to call the IsPresentationOpen function.

In your code, replace this file name with the name of your presentation. Sample Visual Basic Procedures ------------------------------ Sub Driver() Dim IsOpen As Boolean ' Check to see whether test.ppt is open. IsOpen = IsPresentationOpen("test.ppt") ' Process the return value from IsPresentationOpen. If IsOpen = True Then MsgBox "The presentation is open.", vbInformation Else MsgBox "The Presentation is not open.", vbInformation End If End Sub ' Function Name: IsPresentationOpen() ' Arguments: A string that represents the name of the presentation. ' The string can include the full path or just the ' presentation name. ' Returns: True if the presentation is open ' False if the presentation is not open Function IsPresentationOpen(strPresName As String) As Boolean ' An object reference to a presentation. Dim oPresObject As Presentation Dim boolIsFullPath As Boolean ' Check to see whether the full path was passed. If (InStr(1, strPresName, ":\")) = 0 Then boolIsFullPath = False Else boolIsFullPath = True End If ' Loop through the open presentations. For Each oPresObject In PowerPoint.Presentations If boolIsFullPath = True Then ' Check for a match. If (StrComp(oPresObject.FullName, _ strPresName, _ vbTextCompare) = 0) Then IsPresentationOpen = True Exit Function End If Else ' Check for a match. If (StrComp(oPresObject.Name, _ strPresName, _ vbTextCompare) = 0) Then IsPresentationOpen = True Exit Function End If End If Next oPresObject ' No match found. IsPresentationOpen = False End Function REFERENCES ========== For more information about creating Visual Basic for Applications macros, click the Office Assistant in Microsoft PowerPoint, type "how to create a macro" (without the quotation marks), click Search, and then click to view "Create a macro in Visual Basic Editor."
