http://blogs.msdn.com/tess/archive/2008/02/19/high-memory-usage-with-usercontrols-in-ie-using-debug-diag.aspxI was helping a colleague with an interesting case yesterday concerning a memory leak in IE when using winforms usercontrols. We got a nice little repro with a very basic user control that displayed a picture and each time the page was refreshed it appearedsv-SECommunityServer 2.1 SP1 (Build: 61025.2)http://blogs.msdn.com/tess/archive/2008/02/19/high-memory-usage-with-usercontrols-in-ie-using-debug-diag.aspx#7806450Wed, 20 Feb 2008 03:36:23 GMT91d46819-8472-40ad-a661-2c78acb4018c:7806450Brian<p>Excellent timing. Just last week I encountered the exact same issue. As part of our testing infrastructure, we generate data in HTML format which is then rendered into charts, often extremely long with scroll bars. There are hundreds of tests and we needed to capture an image of the results and paste it into an Excel report. Doing it manually would take too long, so I created a tool to automate the task. I used the Browser control in conjunction with Navigate() and DrawToBitmap(). However, with each call to Navigate, memory increased dramatically and was never reclaimed until I ran out of memory. I never discovered the problem, but I worked around it by manually recreating and disposing the control and forcing a GC with each operation. The tool is functional now, but I may later try adjusting the lease time.</p>http://blogs.msdn.com/tess/archive/2008/02/19/high-memory-usage-with-usercontrols-in-ie-using-debug-diag.aspx#7810987Wed, 20 Feb 2008 08:24:36 GMT91d46819-8472-40ad-a661-2c78acb4018c:7810987Christopher Steen<p>Link Listing - February 18, 2008</p> http://blogs.msdn.com/tess/archive/2008/02/19/high-memory-usage-with-usercontrols-in-ie-using-debug-diag.aspx#7811030Wed, 20 Feb 2008 08:28:12 GMT91d46819-8472-40ad-a661-2c78acb4018c:7811030Christopher Steen<p>Link Listing - February 19, 2008</p> http://blogs.msdn.com/tess/archive/2008/02/19/high-memory-usage-with-usercontrols-in-ie-using-debug-diag.aspx#7811035Wed, 20 Feb 2008 08:28:29 GMT91d46819-8472-40ad-a661-2c78acb4018c:7811035Christopher Steen<p>AJAX Ajax Security [Via: David Hurth ] ASP.NET High memory usage with usercontrols in IE (using Debug...</p> http://blogs.msdn.com/tess/archive/2008/02/19/high-memory-usage-with-usercontrols-in-ie-using-debug-diag.aspx#9006684Mon, 20 Oct 2008 01:34:20 GMT91d46819-8472-40ad-a661-2c78acb4018c:9006684Alvin Bruney<p>Thank you for loving my article Tess :-)</p>
