PDFsharp & MigraDoc Foundation

Hi. First I would like thank everyone involved for their work on this project. It made my life much easier when I was given a a large project with a ridiculously short time line and an unknown in the project was writing information out to a PDF.

I am using PDFsharp, WPF build and V1.3.

So my situation is that I take an existing PDF, I open it and write a jpg image over one of the pages and close it. This process works great in development and when deployed on IIS6 and Windows Server 2003. When I deploy it on Windows Server 2008 Web Edition SP1 it works 95% of the time. The other 5% I get the exception pasted at the end of this post.

I have searched and the only reference I can find to anything like this is here.

One of the comments has this piece of information but I cannot find any other information on it.


That comment makes it sound like a Windows problem. Have any of you had any experience with this error? or any thoughts on what I might be able to do to work around it with your library to make this process run at five nines?

Thanks for your input.

Hi,

I don't know if you still have the problem, but I had the problem because of a lock on the image file. After unlocking the file, the problem was solved.

Success,
