Re: Find highest XML value in SeMartens13-Jan-09 1:32 SeMartens 13-Jan-09 1:32  Hi, first of all i wouldn't use an XML-class to load the dataset, this will be propably to slow. Try to use a stream to read the file line by line. There you could extract the y-value using a regular expression, or if all values have the same length (y is at the same index in every line) access it by its index. Then store the highest y-value somewhere and compare every y-value with this one. If the current y-value is higher overwrite the stored value. This algorithm has a complexity of O(n). If you are using multiple processors you could think about splitting the file in two or more parts and use threads to accomplish the task. Hope this helps you a bit.

But being an "old style" .net programmer I thought there was a more effective built in way to do it. Stream and loop, simple enough... <p x = "-0.975586" y = "0.000274252"/> <p x = "-0.975342" y = "0.000164965"/> <p x = "-0.97583" y = "0.000365295"/> <p x = "-0.97583" y = "0.000365295"/> <p x = "-0.974854" y = "-1.00148e-005"/> I'll skip the regex and find the position fo "y = " and "/>" and grab the string between those positions. ASP.NET 2.0 App Crashes tadhg8813-Jan-09 0:08 tadhg88 13-Jan-09 0:08  Hi All, I have a database driven web app written with C#, Asp.NET 2.0 and uses an SQL Server 2005 back-end. The app usually crashes at least once a day but some days does not crash at all and others it crashes much more often, its like it gets stuck in a loop of constantly crashing. An iisreset fixes the problem so is it safe to assume its iis that is the problem but i really need to find out what the cause of the crash is so im just looking for some advice as to where to start, are there some tools i can use or whats the best way to go about this. Any help or advice would really be appreciated Regards Tim Re: ASP.NET 2.0 App Crashes Reza Raad13-Jan-09 0:13 Reza Raad 13-Jan-09 0:13  what error do you receive when your app crash??? maybe this be related to iis alive connections or etc... first post your error here Human knowledge belongs to the world Re: ASP.NET 2.0 App Crashes Paddy Boyd13-Jan-09 0:43 Paddy Boyd 13-Jan-09 0:43  Have you checked the event log on the server for some indication of what is causing the crash? Also check the IIS log files. Re: ASP.NET 2.0 App Crashes tadhg8813-Jan-09 1:20 tadhg88 13-Jan-09 1:20  I have checked the Event Viewer and the most recent error is: Event code: 3005 Event message: An unhandled exception has occurred.

Thanks for your reply Tim Re: ASP.NET 2.0 App Crashes Paddy Boyd13-Jan-09 1:22 Paddy Boyd 13-Jan-09 1:22  Must be in there somewhere, in the FillPlayerMaxMinAverage method. Re: ASP.NET 2.0 App Crashes Reza Raad13-Jan-09 1:50 Reza Raad 13-Jan-09 1:50  as you think this seems that you have a problem on your code, trace your app and find the problem Human knowledge belongs to the world Re: ASP.NET 2.0 App Crashes tadhg8813-Jan-09 2:13 tadhg88 13-Jan-09 2:13  The problem is i have spent the last ten mins trying to get the same page to crash again and its running perfect now its doesnt make sense, the method mentioned FillPlayerMaxMinAverage does have statName as a param which may have been set to DistanceCovered but it just will not crash again, the page seems to be fine now so im just waiting for the next crash I managed to find the IIS logs, they are very messy, is there some less complicated way to check them ??? Re: ASP.NET 2.0 App Crashes tadhg8814-Jan-09 6:34 tadhg88 14-Jan-09 6:34  Thanks for ur replies guys.... I managed to find that one "Distance Covered" bug buried deep in the code and got it sorted now but the app is still crashing regularly, i have noticed that the majority of the crashes are happening in the Data Access Layer objects when they try to interact with the db. This is the most common crash i am seeing in Event Viewer. But the prob is this method is run regularly and only crashes sometimes.

I was using the windows performance monitor and watching the .NET CLR Memory Total committed Bytes. The memory would just climb higher and higher and eventually the system would crash. I then looked into the Event viewer and we found error messages that lead us to the conclusion that there was a memory leak in one area of the application. The vendor fixed the leak and the system is more stable. Start with monitoring the memory on the IIS server and check the memory usage, you may find a correlation between memory usage and system stability. david msn taskbar window in asp.NET chanzeb12-Jan-09 23:43 chanzeb 12-Jan-09 23:43  Hi everybody, i want to display a popup window like msn. i have done for desktop application. but not for the web application. quick response 'll be highly appreciated.
