SUMMARY
This article contains a sample Microsoft Visual Basic for Applications function named IsPresentationOpen that determines whether a specific presentation is open. A sample macro (Sub procedure) named Driver is also included to demonstrate how to call the IsPresentationOpen function.

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. NOTE: In the sample below, IsPresentationOpen checks to see if a presentation named "test.ppt" is open. 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
