Visio memory problem, when saving images of pages.

[sonzos]

Hey,

Im currently working on a solution, where i need to save each page in a
visio document as a picture.
The problem is the memory, the document is 160 pages.

I use For each to step through all pages of the document, and saves
each page with the page.Export(Filename) function. For each page saved,
visio uses more and more memory. When it is finish, Visio uses 1,9GB of
memory, and it stays at that amount, until i restart visio.

I tried to use GC.Collect(), and setting the
visio.application.undoenabled = false, but neither of them helps with
the memory.

I use VB.Net.

How much memory does Visio use without exporting the pictures? By this I
mean that you should comment out the line of code that exports the image but
keep the code that iterates through 160 pages. I'm wondering how different
the memory usage is.

Hey,

The visio-file is about 15 Mb, and when it is loaded in Visio, it uses
about 200 Mb of ram. When the code iterates the pages without the
export function, it only uses 30-50 Mb of extra ram. So it is the
page.export(filename) function that uses the large amount of ram.

Found one error in our program. We were running the whole thing in a
thread. We tried not to, and then we used less ram. But Visio still use
about 1 Gb ram, when it is finish with the export of all pages.
