It takes 1 minutes 40 sec to read 2218 entries from a remote workstation. I need to use the Listview to keep a similar look and feel as the Windows NT event log viewer.

Maybe you can display only the errors. I tried your code on 1000 entries, writing only the errors to xml and it performs quite nice. Thanks for the snippet. I was not aware of how easy this Was. I've incorporated it into my dataaccess/debug/tracing framework. -----Original Message----- From: Powell, Simon [mailto:[EMAIL PROTECTED]] Sent: vrijdag 31 mei 2002 10:04 To: [EMAIL PROTECTED] Subject: [DOTNET] Eventlog Viewer Hi, I'm still fairly new to .NET, but I want to create an eventlog viewer using C#. Attached at the bottom is some code I've already written. My problem is that I can't match the performance of the Windows NT eventview for reading the application event log. I can read a remote machine's app log in seconds, but my code takes over a minute to read the same information. How can I improve my code? Someone out there must have tried already? Or should I just give up and use a diffent language (C++)? If I try a listBox (rather than listView), I get a small improvement, but nothing to match the eventviewer. What am I doing wrong? I am the only one trying this? If Microsoft in the future will be using C# to build their OS, will they be using the eventlog class and a listView control, if so how will they achieve acceptable perform? Is there a good book out there that would help? Any help would be much appricated. Simon (frustrated and about to give up...)
