Argument Out of Range Exception

The problem occurs with the SGSFA.cs file under this scenario:

1) The program copies slides (copySlide function) from an existing presentation (Presentation A) to a new presentation (we’ll call Presentation X).
2) The program then runs "sgPres.Write(sgPPTPath);"
3) No errors occur.
4) Then the program copies slides (copySlide function) from another existing presentation (Presentation B) to Presentation X.
5) The program then runs “sgPres.Write(sgPPTPath);” and encounters the error.

This error is consistently thrown when the Presentation A has greater than 50 slides.

Thank you for your time.

I am receiving a similar message as Sergio with version 7.5.1 on Aspose.Slides:

System.ArgumentOutofRangeException

This occurs when I append slides to an existing presentation (40-50 slides).

Hi John,


Thanks for your interest in Aspose.Slides.

I have observed that you are using the latest version of Aspose.Slides for .NET to reproduce the issue. Please share the sample code reproducing the issue along with source presentation with us. I will investigate the issue further on my end to help you out.

Many Thanks,

Attached is the code and example slides.

The main function is orgToSGSlideHandler and the error is happening within this function at:[...sgPres.Write(sgPPTPath); }

catch (Exception ex7) {

logError(errorFile, -1, orgPPTFileName, orgPPTPath, ex7);

} return true;

}]

Is there an email address I can send the slides to? I'd rather not attach them in this post.

Hi John,


Thanks for sharing the sample code. You can send the presentation file to me privately by following the guidelines mentioned here. Please notify me here in this thread once you have shared the presentation file. I would also appreciate if you may please share the sample application along side as it will really help in expediting the issue verification process.

Many Thanks,

Thanks for the information. Hopefully you should see two emails in your inbox.

Hi John,


Thanks for sharing the requested information. I have observed the presentation and sample project. Unfortunately, I am unable to use the sample project shared owing to missing namespaces that you have available on your end. The sample project seems to be the entire solution. I would humbly request you to please share the subset of sample code or sample project that is related to Aspose.Slides issue and that you use on your end to reproduce the issue. I will be able to carry my investigation on the basis of that. Unfortunately, it is difficult to develop an understanding of the complete project shared by you to identify the cause of the issue. I will really appreciate your cooperation in this regard.

Many Thanks,

Hi John,


I have observed the comments shared by you and based on them, I have extracted the relevent code sample portion from your sample project that you have pointed is cause of issue. I have shared the working sample code for your reference as well. I have observed two presentations with name OIT.pptx and MPRMetricTemplate.pptx in your sample project. I have tried cloning the slides from OIT.pptx to new presentation and have observe no issue. Can you please share that actual presentation with more than 50 slides that you feel is source of the issue so that I may investigate that further on my end. Please verify the same presentation with sample code shared by me before passing that on to me.

Many Thanks,

Thanks for the email. I’ll test version 7.6 and let you know what happens.

I was able to reproduce the error with version 7.6 of Aspose.Slides. On SGSFA.cs I catch an exception ArugmentOutOfRange with this message: {“Value must be positive.\r\nParameter name: count”}

I will send you the solution.

Thank you for your time.


Hi John,


Sure, I will await further response from your side. I would request you to please share the sample solution in the form of subset of your solution narrowing the issue to Aspose.Slides as it will allow us to quickly reproduce and resolve the issue.

Many Thanks,

Please confirm you’ve received my email with Solution.zip. The Aspose
site is slow to load from where I am, and I can’t confirm.

Thank you for your time.

Hi John,


I regret to share that I have not been able to receive any solution from your end. Can you please re-send so that I may commence my investigation?


Many Thanks,

You should have received two emails.

Thank you for your time.

Hi John,


Thanks for sharing the requested information. I have received one email with attachment with Sludes.zip. Unfortunately, for your second email the mail server has found that malicious and discarded that. Can you please verify your second attachment and kindly send that again. Please also provide the details about the shared attachments that what I should verify in them.

Many Thanks,

The first attachment represents the slides used by the program.

The second attachment should have the Visual Studio files in it.


I just sent the second attachment again.

Hi John,


Thanks for sharing the sample project. Unfortunately, its a complete project with custom namespace used. I am unable to use the sample project on my and as I requested you earlier to kindly share the sample application or working sample code related to Aspose.Slides issue that I may use to reproduce that on my end and help you further. Unfortunately, it is really difficult to develop understanding your sample project and then identify the issue. Therefore, I humbly request you to please share the subset sample code/application that is related to Aspose.Slides and is reproducing issue on your end. I will use the same on my end to help you further.

Many Thanks,
