Unknown errorcode in COMException working with Visio files

Question

Hi!

When I try to convert Visio files via code on sharepoint site, on the line

app.Documents.OpenEx(documentName, (short)VisOpenSaveArgs.visOpenCopy);

(app is InvisibleApp, documentName is correct, and I've also tried some combination of open flags)

I catch  COMException with ErrorCode -2032463768, InnerException is null and Message "An exception occurred" (so descriptive, yep). It's obvious that I got this exception from visio.

What this error means? And how to fix my code to solve this problem?

In general I need to convert vsd-files stored in doc library to vwd-files and put them to another doc library. before convertion I save vsd-file on local drive in temp folder. Maybe it's a wrong way for my task

In addition, I heard that there was the same problem using Sharepoint 2007

Answer 1

Automating Visio (Office client applications) from server side is not a stable design. Please refer to article http://support.microsoft.com/kb/257757 for more details. If it fits into your design, you can do the conversion part from a windows based application (which can automate Visio to do the conversion).

Thanks.
