Create PowerPoint File

VB.NET method and sample code in this part will teach you how to create a fully customized blank PowerPoint file by using the smart PowerPoint presentation control. Here are the example to get you started.
Please refer to following API to create and define a new blank PowerPoint document with a user-defined presentation slides count.
Private Sub New(pageNum As Integer)
End Sub
Use VB demo code below directly to create an empty PowerPoint document with a particularized file name.
''' <summary>
''' Create an empty PowerPoint document.
''' </summary>
''' <returns></returns>
Public Function CreatePPTXDocument(pageNum As Integer) As PPTXDocument
Return New PPTXDocument(pageNum)
End Function
Code instructions:
  • "int pageNum": can be used to specify the PPT slides number. For example, if you need to create a PowerPoint document in 5 slides, you may just input "5" in the demo code.

Load PPT Document

If you want to do any further PowerPoint viewing or processing within VB.NET project, you are supposed to load the source PPT document at first. By using this marvelous VB.NET PPT file starting program, you can load and embed target PowerPoint from both local file and memory with sample methods and codes below.
Check following APIs for loading PPT presentation from file and stream.
''' Load a present PowerPoint document in local file.
Private Sub New(filePath As [String])
End Sub
''' Load from Stream.
Private Sub New(sourceStream As Stream)
End Sub
Use following sample VB codes to load a certain PowerPoint document.
''' <summary>
''' Load PPTXDocument from native PowerPoint file.
''' </summary>
''' <param name="filePath"></param>
''' <returns></returns>
Public Function LoadPPTXDocumentFromFile(filePath As [String]) As PPTXDocument
Return New PPTXDocument(filePath)
End Function

''' Load PPTXDocument from stream.
Public Function LoadPPTXDocumentFromStream(sourceStream As Stream) As PPTXDocument
Return New PPTXDocument(sourceStream)
End Function
Besides, users also can get the precise PowerPoint slides count as soon as the PowerPoint document has been loaded by using the page number getting method.
Private Function GetPageCount() As Integer Implements PPTXDocument.GetPageCount
End Function

''' </summary>
''' <param name="doc"></param>
''' <returns></returns>
Public Function GetPageCount(doc As PPTXDocument) As Integer
Return doc.GetPageCount()
End Function
