Increasing memory leak with batch writing

Wed, 11 Mar 2009 18:15:52 Z

Hello All,

I have a problem of increasing memory allocation when I use VisualsToXpsDocument to batch write a large number of pages (1000 pages) with print ticket to Xps document.

Here is the code that I used:

// use batch writer with ticket

_ xpsBatchWriter = static_cast<VisualsToXpsDocument __gc*> (_xpsDocumentWriter ->CreateVisualsCollator());

_xpsBatchWriter ->BeginBatchWrite();

for (int i = 0 ; i < 1000 ; i++)

{

ticket = __gc new PrintTicket();

containerVisual = __gc new ContainerVisual();

pageMediaSize = __gc new PageMediaSize(sz.Width, sz.Height);

ticket ->PageMediaSize = pageMediaSize;

ticket ->PageOrientation =

(sz.Width > sz.Height)? PageOrientation::Landscape : PageOrientation::Portrait;

containerVisual ->Children->Add(fixedPage);

_xpsBatchWriter ->Write(containerVisual , ticket );

}

_xpsBatchWriter ->EndBatchWrite();

The allocated memory will continue to increase with each page written.

I don't know if there is some resources should be released or is it a bug at DotNet framework.

I'll be so thankful if anyone could help me.

Regards,

Hmeidi.

Where are Microsoft guys to defend their toolkit?

I said that their is a memory leakage bug in DotNet Framework 3.5, am I wrong??

maybe same problem I've faced in the past... does it get better when you try following:

a) calling Measure/Arrange/UpdateLayout to the Visual, and/or
b) call UpdateLayout at least to one/first fixedPage of the FixedDocumentSequence

maybe it helps!?
