dr.Close();
AEConnection.Close();
i think here u have done wrong, and before redirecting close your all connections
better use using block
and also there is no try catch finally block use them to tackle any runtime errors or db error.

Take a look at the using statement. This is an elegant way to handle this, so that your connections and commands get closed. For instance, here's a very simple implementation:
using (SqlConnection conn = new SqlConnection (connectionString))
{
using (SqlCommand cmd = new SqlCommand(cmdText))
{
... Do something with the database here.
Response.Redirect("Error.aspx");
}
}As the command and connection are wrapped in a using block, they are both disposed for you automatically (which also closes the command and connection). This command effectively creates a try/finally block where the finally contains the Dispose command for the relevant object.

Hi everybody
How can find out number of characters in a file?

File.ReadAllBytes.Count, or something like that
You may be able to get it from the FileInfo class also.

That'll work for ASCII and UTF-32, but not for UTF-8 and some other encodings with variable character length. File.ReadAllText(path).Length should work better.

Depends, if it's a text file or a binary file, and if he wants file size, or number of characters.

After spending the last few months reading about Test Driven Development I am a complete and utter believer. Unfortunately I'm still inexperienced and need advice on unit testing a class which incorporates a timer.
For example I am building an ActivityMonitor class which would be used to detect an activity timeout on a class (typically a mediator for a windows form) and reset it. I'm envisioning something like this:
ActivityMonitor
..private Timer _timer;
..private EventDelegate _timeout_callback;
..ActivityMonitor(EventDelegate callback, int timer_interval);
..public Reset();
How do I test something like TimeoutRaisesCallback? I could set the timer of course and wait for the callback but that would just slow down my unit tests. Do I merely set it to something very short like a few milliseconds and take the hit? Or is there a better standard way to handle this?
Also, suppose I have a class that uses the Activity Monitor:
ClassThatUsesActivityMonitor
..private ActivityMonitor _activity_monitor;
..ClassThatUsesActivityMonitor() {_activity_monitor = new ActivityMonitor(new EventDelegate(Reset));}
..public Reset();
..public DoSomething();
How do I go about unit testing that ClassThatUsesActivityMonitor reacts appropriately if the ActivityMonitor calls its Reset() function while DoSomething() is executing?
I look foreward to your responses, thank you very much,

ItIf you have a datagrid, you have an ASP.NET website. This will run inside your web browser, how do you want to interact with it, in code ? You want to insert values ? OK, in that case, you need to access the HTML of the current page, parse it and modify it.

I am writing a web app where I have a staff heirarchy, coaches, business manager, ect.
I have an area where you fill in contact information for these people, along with parents and any other contacts you may have.
I want to be able to have a button on one page that says "Choose Coach" for example, and it brings up the list of people I entered, lets me select one, and then save it.
I can do all the selecting and saving side of it. I don't know how to have that page come up and then page it back to the parent page.
I am using ASP.NET. Any ideas?

I am confused, + * ()... are not escape chars? what are you trying to exclude none alpha chars?
this RegEx will remove all except alpha-numeric.
string newString = Regex.Replace(oldString, "[^A-Za-z0-9]", "");
