I am trying to write an application that monitors internet usage. So it sort of needs to act like a firewall/proxy, recording each site the computer goes to. It will record all these sites in a log file. Using a proxy server on the network is not an option, each computer running this software needs to be self sufficient. Do you have any suggestions on what to use for this project?

From where .NET knows that he need to use the german locale?

View 6 RepliesI am trying to return a javascript function using response.write in an aspx page. The problem is that the function i am returning has lots of quotes and they are conflicting with the repsonse.write syntax. Here is a sample code:
Response.Write(" If hello.StartsWith("H", StringComparison.InvariantCultureIgnoreCase) OrElse hello.StartsWith("W", System.StringComparison.InvariantCultureIgnoreCase) Then")
This is giving me a problem as the quotes inside are cutting off the response early. Is there a better way to do this?

I am getting an intermittent "System.Web.HttpException: Request timed out." error when my code hits the line response.write():
sMessage = "Searching...0% complete."<br>
sSetVal = "<script>document.getElementById('MessageDiv').innerHTML='" & sMessage & "';</script>"<br>
Response.write(sSetVal)
Note that Response.BufferOutput = false is set when the page first starts executing (well before the above code executes).The code is used to update a progress message while other threads execute long-running processes. One thread runs continuously and checks the status of the other threads. As the other threads finish, this thread outputs updated status messages to the end user. I realise that this could (should) be recoded using ajax, but it is a legacy app and that is not an option at the moment.
This code is run 10,000+ times a day, and the error only occurs about 5 times - so I suspect the response object is being blocked by other threads when the website gets busy. However, I don't know which performance counters to check in the performance monitor. Or is this problem caused by something else? I am using IIS 6, asp.net v2 and vb.net?

View 7 RepliesI have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

I was thinking in doing some voice chat in my application which requires the use of UDP.
If you know any useful articles or can give me a boost I will be very glad and obliged.
i am a beginner in vb.net programming...started a project in it.Below is the breif project description.The application is to ensure the integrity of the files.Following are the majors things that i have to implement
1. To browse the files from the disk on runtime.initially i am just taking the database files so it's basically to connect with the MS access db files.
2.To apply the different hash and encryption algos on the file.
3.To store the results on the hard disk back.
4. To calulate the performance of each algo using some performance matrix.(TIME,MEMORY USAGE etc)
Now i am having problem in two things.First in runtime connectivity with MS access batabase..and secondly and the main problem is that i could'nt find any appropriate builtin function to calulate the processing TIME and the MEMORY usage.
instead of using if control.invoke required in a procedure can I just call the procedure with begininvoke?I have, possibly, the following:
Private Sub UpDateTimer_Elapsed(sender As Object, e As System.Timers.ElapsedEventArgs) Handles UpDateTimer.Elapsed
UpdateTime()
If MicActive Then
PTTCancelTime += 1
