Security problem on Remote Host

[cheese_block]

Hi,

We’re using ASP.NET to automate the production of powerpoint presentations.
I’ve just moved to a remote server for testing. When I run the system I get
the following:

[SecurityException: Request for the permission of type ‘System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089’ failed.]

It seems to be failing on the following line of code:

presEx = New PresentationEx(BaseDirectory & str2007BaseTemplate)

The 2003 version of this runs fine:

pres = New Presentation(BaseDirectory & str2003BaseTemplate)

Is there anything I need to do to get this to run?

Thanks
Dan

Hi, I’ll try and put something together when I can.

Are there any immediate thoughts on what might be causing the problem? I saw a similar problem with Word where it was trying to create a temp directory.

Cheers

This is the thread I saw about the word problems

Security problems with Aspose.Words in a hosted environment

I am using GoDaddy for hosting, and I am having difficulty with the Aspose.Words component. Any assistance you could provide would be greatly appreciated. Here is my code: private static byte[] ConvertDoc(Stream FileToConvert) { Aspose.Words.Document srcDoc = new Aspose.Words.Document(FileToConvert); MemoryStream xmlDoc = new MemoryStream(); srcDoc.Save(xmlDoc, Aspose.Words.SaveFormat.AsposePdf); xmlDoc.Position = 0; Aspose.Pdf.Pdf destDoc = new Aspose.Pdf.Pdf(); destDoc…

And some details from Fasthosts about security problems:

Hope that’s enough to go on.

Hi Dan,

I have observed the issue shared by you. An issue with ID 30043 has been created in our issue tracking system to further investigate this issue. We will share the information with you once the investigation is carried by our development team.

We are sorry for your inconvenience,

Hi, any update on this? thanks

Hi Dan,

The issue has been scheduled for investigation in week 37 of 2011. In light of our initial investigation, we believe that PresentationEx constructor used by you in your configuration needs more security permissions than Medium Trust security level provides. It will be really appreciable if you may please provide us with more detailed information about the web server and server configuration. The PresentationEx constructor requires following security permissions. The following is output from permcalc utility that shows permissions needed to run PresentationEx constructor:

Can you please also try Full Trust security level for instance to verify the things. Please share the detailed information as requested in this regard.

Thanks and Regards,

Hi, I had a problem with a Fasthosts server I was using. I’ve now moved to a separate standalone server (again with Fasthosts) and it works fine, so I don’t have the problem anymore.

Thanks
