I get this error, "Specified argument was out of the range of valid values", when I try to write a PPTX to an output stream.  However if I write to a file instead, the presentation is output correctly.

writing to the response stream fails...

System.IO.Stream st = this.Response.OutputStream;
presEx.Write(st);

but this works ok...

presEx.Write("myfile.pptx");

Any ideas?

Hello,

Thanks for reporting.

I can replicate the problem with the following code. We will fix it as soon as possible.

PresentationEx presEx = new PresentationEx("C:\\source\\source.pptx");

this.Response.ClearContent();

this.Response.ClearHeaders();

this.Response.ContentType = "application/vnd.ms-powerpoint";

 

System.IO.Stream st = this.Response.OutputStream;

presEx.Write(st);

this.Response.End();
