My Favorite System Net Trace Configuration File Dumps Process Id And Date Time Information

24 Mar 2009

Often you need to correlate a .NET trace with a <a title=”Netmon” href=”http://www.microsoft.com/downloads/details.aspx?FamilyID=f4db40af-1e08-4a21-a26b-ec2f4dc4190d&DisplayLang=en” target=”_blank” mce_href=”http://www.microsoft.com/downloads/details.aspx?FamilyID=f4db40af-1e08-4a21-a26b-ec2f4dc4190d&DisplayLang=en”>Netmon</a> trace.  To do that you need the date and time of the call from the <a title=”System.Net trace” href=”http://msdn.microsoft.com/en-us/library/ty48b824.aspx” target=”_blank” mce_href=”http://msdn.microsoft.com/en-us/library/ty48b824.aspx”>System.Net trace</a>.  This will do it!

Useragent Call Results In Error Not Enough Storage Is Available To Complete This Operation

13 Jan 2009

I was able to cause this error in Internet Explorer 6 and Internet Explore 7.  I found that editing my registry entry so that the user agent was greater than 260 I could cause this error in jscript dialogs.  By removing entries to get below the size I could avoid the error.  This is the registry location for the user agent strings (see http://support.microsoft.com/kb/218933 for setting this using IEAK):

How To Modify Injected Attributed Code In An Atl Control That Is Crashing

17 Dec 2008

(ATL Control Visual Studio 2003 Crashes long value) I found a problem in the injected code from Visual Studio 2003 for an ATL control that had a property that was a long (VT_I4) value.  You could reliably crash the control if you put it into an html page and had jscript in a loop, setting the value over and over (100 X) in this case would crash it.  To make the crash reliable, I turned off BSTR caching and set full gflags.  You could see the issue was the freeing of a BSTR twice.
