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
