I'm writing an application that has to record data @ ~ 500 HZ for hours on end.I'm noticing that when the file size is greater than 20 MB that a text line append is slowing the system to a crawl.Aside from splitting the files into smaller items is there a better way to do this?
Using writer As StreamWriter = New StreamWriter(DataLogPath, True)
writer.WriteLine(dataEntry)
End Using

I'd like to create a new file everyday for a logging application to minimize size when accessing. I'm after a couple of pointers with respect to when to create the file, and what checks to do etc.

I'm getting desperate here trying to find the problem, and I don't know where to start looking for it.
Here are the symptoms:I've noticed, that when a user logs on in the morning, he is then immediately logged off, then when he logs on again, everything is fine and he can work on the site.
Every once in a while, when the user clicks a link, the page takes a lot of time to load, but it never actually loads, and the user is thrown to the login page.Also, after an Exception has occurred in the website, the user is then thrown to the login page. It's as if the exception clears somehow the session.

I have inherited a ASP.net site, and I've made some changes too to some of the VB code and CSS, and have hosted it on a FTP. It uses an SQL DB to allow users to log in and calls stored procedures.The site complies with no errors, and allows me to log in as a user, and can works perfectly on testing.However, once uploaded to the FTP, it no longer allows me to log in as a user. It hangs for a while, and then returns a message saying that the password is wrong, despite it being correct. It doesn't throw an error message, and I think I've narrowed it down to something to do with the Web.config file, but I'm at a loss as how it's not working, especially with the lack of error messages being thrown.[code]
View 2 RepliesI was wondering is there a way anyone knows of to "inject" a logger into an application such that it passively monitors the thread and quietly logs processes as they occur without having to do things like: [Code] It would then monitor everything that goes on inside of that method including passed in arguments along with method calls and values passed into those methods, exceptions that occur etc. Has anyone implemented something like this in the past? Could it even be implemented? Is logging in this fashion just a pipe dream?
View 6 RepliesI have a class for serial communications (call it CSerial), based on a property value (CSerial.LogLevel), I'd like to produce various levels of logging information about data sent and received to the serial port.Given that it's a reusable class, there's no way of telling whether the log data should be sent to the console, a text box, a file, etc. This would be determined by the application using the class, so I can't write all of the different output options into a method in the class.Question:What's the best way to implement this? I have some ideas:1. Create a Log method and then "override" it in my main application to handle the most suitable form of output? Can I "override" a method as part of an instance? Or do I need to create a new class that inherits my original one, override the method there and then create an instance of my new class?

I've been assigned to start a new Logging Project from zero in VB.NET.The final exit of the main project is information organized in paragraphs like this:
[code]...
Every paragraph correspond to a database connection. Every connection is made with an entire diferent database.i need my logging project to save everything the user does, so the logging exit would be like the system exit but with exceptions and other important information like this: Paragraph's title 1 Paragraph's content 1.Paragraph's title 2 User wasn't able to see this information because an exception ocurred: System.WhateverException:couldn't connect to WCF.as you can see the exit is the same but i need to create a detail log because the information is delicate and the DBA needs to now wich user did what and what was the response of the system. Also i need it to be and independant project so i can re-use it in another projects. Seeing the final exit of both the main project and the logging project, what would you recommend me to use for logging in .NET?
We have a current implementation of a log file manager where it's two main purposes are to 1. rename files generated by other programs with a date/time stamp so they create new ones, and 2. delete files older then X amount of days from a specified folder. The program also makes it's own log file which records when these events happen.Do you think the Logging Application Block would be useful in this instance? The old file manager is written in VB 6.0 and an upgrade to VB .Net would not take too long, but is it worth it to try and implement LAP into it?

Im currently writing a code that can log ALL of the IP(')s that view a site. I kinda want a code that goes something like

Or something similar is fine also.After that I want the logs to be saved into a txt file, (I can do this part)Then the user will enter a new site to be logged. Once that is done that will also be saved into a txt file. Etc....Then finally if any IPS that are the same show up in the text files then the user will get that IP in a textbox.
I just got finished watching a short video on logging using some of the built in concepts in Visual Studio 2005. This seems to do a good job. My question is why do people look for other solutions to logging such as Enterprise Library or Log4Net when there is a simple solution out of the box?
The video I watched primarily used the following for logging.
Code: My.Application.Log.WriteEntry(sb.ToString, type)
I am trying to implement a simple log using Nlog 1.0, using the following code

View 1 RepliesSo I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:

SHOWNAME
CALLNAME
BREED

So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
