Unfortunatley the data is not a .csv file... But would it be easier if I just concerted the .txt file over to a csv file? So there is whitespace that I have to deal with.

The Regex pattern could get as detailed as you like.
Untested:
<br />
using (StreamReader sr = new StreamReader("File.txt")) <br />
{<br />
string line;<br />
while ((line = sr.ReadLine()) != null) <br />
{<br />
if Regex.IsMatch(line, @"\d+ bytes sent")<br />
Console.WriteLine(line);<br />
}<br />
}<br />

Thanks for all the help Bitwise...... This seems to easy though. Is this the bestway to implement this?

I have a server which updates programs on our local network, informs of notifications, etc... The problem is that after so long it will "lock up" and stop accepting connections. I have connected/disconnected clients and tested everywhere for a solution to the problem. There is actually a series of about 6 servers on different ports, and all of them quit accepting at once. The MainSocket is using Socket.BeginAccept and waiting for connections, then passes them off to a data structure I created to maintain the connections/user info/etc. Is there a certain period of "idle time" when the Framework aborts that thread? It seems like if that were the case, however, you wouldnt even be able to connect to the server. As it is, you can get a connection, you just cant communicate. I know without seeing the code it may be hard to determine a solution, but Im not sure exactly what the problem is. Any thoughts or comments would be appreciated...

did you say that all disconnect or stop accepting connections at the same time? Have you tried running the server and client on your machine to see if they stay up and running?
What about traping the socket errors are they reporting anything?

Yes, that is how I tested them to get the bugs out (On My Machine). It takes a good 2 days or so before they stop accepting connections, however, and debugging for that long really isnt feasible, because it doesnt always happen. It does report errors, but the error logs dont report anything unusual, client connected/disconnected, updating database, etc. Nothing that should clog the server like that. Thanks...

How are you running this? Windows service? ASP.NET? Windows app? Command line? Different/same PC?
Maybe the hardware is going into power saving mode...

I created a tabbed app that has a number of checkboxes on the second tab. I'm using currency manager to keep track of the number of records that are currently in the DB as well as adding, deleting records. I also am using data view to sort my records based on what the end user is looking for.
When I go to add a new record and click on the second tab, I get a DBNull exception.
I've made sure that the fields in the database are set to not allow nulls, and with a default value of zero.
I want to do a check to make sure that if the field is null then the binded field = false?
Or is there a better way to do this?
Thanks

To Check if a field's value is null:
dataset.tables[0].row[0]["Field_Name"] == DBNull.Value
Was it a cat I saw?

Thanks but I ended up fixing my problem this way.
Right before I add a new record I set the default value of the columns
ds.Tables[0].Columns["FieldName"].DefaultValue = false;
This seems to have done the trick.
Now I'm having problems saving mulitpule times on the same record.
Thanks

What are the 2 errors?
Which version of the .NET framework are you running? (ParameterizedThreadStart is only in version 2.0 or higher)
|
|
|
|
|
Ah
The type or namespace name ParameterisedThreadStart could not be found
I use 1.1
So how I can get rid of that.
Please help
eric
|
|
|
|
|
get VS05 and use the 2.0 framework or find the 1.1 equivilant to the code.
|
|
|
|
|
Well, I just got the same errors in VS.Net 2005
So it's not because of the framework version then
Please help
eric

Make sure you've got
using System.Threading;
at the top of your .cs file where you use ParameterizedThreadStart.
You can read more about it here[^].
There are several alternatives though, including some that work on all .NET versions. Here's another way of starting a new thread, using Delegate.BeginInvoke:
public class MyClass
{
public delegate void FunctionThatTakesAnArrayList(ArrayList argument);
...
void StartTheThread()
{
FunctionThatTakesAnArrayList function = ThreadedArrayListUsage;
function.BeginInvoke(myArrayList, null, null);
}
void ThreadedArrayListUsage(ArrayList list)
{
}
}
Here's another way, using the .NET thread pool:
void StartTheThread()
{
System.Threading.ThreadPool.QueueUserWorkItem(ThreadedArrayListUsage, myArrayList);
}
void ThreadedArrayListUsage(object state)
{
ArrayList list = (ArrayList)state;
}

Hi:
I selected Tooltip from the toolbox and clicked on the form and then for the contriols I want a tooltip, I went to the properties and entered the text I want to show (I tried with an without double quotes).
But I cant get the tooltip to show up. Please could you tell me if I am missing doing something?
Thanks, smurfy

Hey Smurfy,
Are you talking about Windows or Web application?

Hi Manas:
this is for a windows application.
Thanks, smurfy

I've had various issues with tooltips before as well. What I've found is that if I don't set the tooltip text at form load then the tooltip will never show up. I've often found that I have to set generic text and then set the tooltip active property to false until sometime later in my code I set the text I need and mark the tooltip active again. Using this method works every time. Maybe a bug in c# but i'm not sure.
Oh, and if you need the tooltip to show up even if the control it's bound to isn't the active control of the form then set it's show always property to true.

thank you I will try that out.
