    Object Reference not set to an instance - Init of Presentation Object .NET

    Hi,

    I downloaded latest version of Aspose.Slides for .NET 4.1.0, I generated temp license and included in the code. While instantiating Presentation object with FileStream in constructor i get "Object Reference not set to an instance" error. 

    This is the code, its an windows forms application

     Dim fis As FileStream = New FileStream("test.ppt", FileMode.Open, FileAccess.Read)

     Dim license As Aspose.Slides.License = New Aspose.Slides.License()
     license.SetLicense("Aspose.Slides.lic")
     Dim objPres As New Presentation(fis) 'Throws error here

    I did go through this Post but nothing helped me.

    I'm using VS2008 with target framework 3.0

    Can you please let me know whats that i'm missing here? 

    Thanks,
    Raj

    Hi Raj,

     

    Thanks for showing your keen interest in Aspose.Slides.

     

    I have tested the code snippet that you have shared and I am unable to reproduce the problem. Please share some more details about your project. However, please find below the correct procedure for instantiating a presentation object.  

     

            Dim fis As FileStream = New FileStream("C:\\Sample.ppt", FileMode.Open, FileAccess.Read)

            Dim license As Aspose.Slides.License = New Aspose.Slides.License()

            license.SetLicense("Aspose.Slides.lic")

        Dim objPres As Aspose.Slides.Presentation = New Aspose.Slides.Presentation(fis)

     

    Sorry for the inconvenience.

    Hi Mudassir,

    Thanks for the reply.

    I thought there might be any size/slide restriction for trial version and deleted few slides from my test ppt file, then it worked, so i dig deep in and found out that once i delete the last slide (12th) it started working. Now i wanted to know if that slide (12th) had anything which Aspose had a problem parsing/loading, so I deleted all the slides keeping that single slide (12th) then again it worked. 

    Now its kinda confusing me. Can you please help me understand why this is happening?

    Thanks,
    Raj

    Hi Mudassir,

    Please find the source and ppt (downloaded from google) attached. I haven't attached the lic file, its a trial license. Please change the path accordingly in the source.

    Thanks,
    Raj
