Visio 2007 Programmatically (C#) Save as Web Page (JPG)

[Woof]

Successfully creating Visio docs on the fly through
Microsoft.Office.Interop.Visio. I can save the newly created doc as a VSD. I
can also see the method to save as a PDF, but I need to save as a JPG.

Trying to use
Microsoft.Office.Interop.Visio.Document.Pages[0].Export("whatever.jpg");
throws an "Invalid container identifier" exception.

Can anyone point me in the right direction???
Many thanks.

Hello Woof,

A few points here:

a) Which 'Document' are you refering to?

b) The Pages collection has an index starting at 1 not 0.

c) The Export method requires a full path to export to (eg "C:\Documents and
Settings\All Users\Desktop\whatever.jpg").

Hope that helps

Best regards

John

Paul & John,

Thanks a million. Problem was the page index (I was already using a full
path). I'm so used to 0 page indexing in my code that I didn't even think
this could be the issue, and 'Invalid Container Identifier' was a little too
vague for me.

Thanks guys.

Try replacing:

mydoc.Pages[1].Export("C:/mymytesttest.jpg");

with

mydoc.Pages[1].Export("C:\\mymytesttest.jpg");

double FORWARD slash = \ escape character

Microsoft.Office.Interop.Visio.Document mydoc;
mydoc = axDrawingControl1.Document;
mydoc.Pages[1].Export("C:/mymytesttest.jpg");

Sorry, not sure my suggestion above will make any difference in hindsight.
