Large object heap fragmentation while creating document


We would like to create a word document in several steps. For each step we are showing progress information in the web user-interface. So for each step we have to load the document again and add the data (at the end of the document).

Loading a large amount of data in memory (and freeing it again) several times will fragment the "large object heap".

How can we append data to a document in several steps without fragmenting the Large Object Heap?

Kind regards,

Thanks for your request. Why do you need to load a document several times? Maybe in your case you can just use Ajax to show document generating progress. There is a simple example in demos:

Hope this helps.

Best regards.
