Hi
I want to import the data available in .CSV file to a table(s)in sqlserver db from C#.net.
User has to choose the .csv file from the frontend and the data from that particular chosen file should be imported to database after the client side validation.
I hope for this , we need to read the specified file from the client machine and write it into the server machine,... i dont know how to handle permission issues and all.
Pls help me out how to do this scenario ASAP...

This is a common question and a quick Google[^] search provides you with plenty of information.

Use .NET remoting and have a normal application listening to your service and then pop up a message. NOT good to have a service showing messages!

Two queations about regular expressions:
(1) Is it possible to define "sub-patterns"?
I have a larger regex containing the same sub-pattern multiple times, e.g.
(?<idA>[a-zA-Z_][a-zA-Z_0-9]*)=(?<idB>[a-zA-Z_][a-zA-Z_0-9]*)
Is it possible to assign a sub-pattern to something (maybe \ö), so that I can use
(?<idA>\ö)=(?<idB>\ö)
?
(2) performance
Are there any general performance guidelines for regular expressions?
I would prefer to break down complex regexes into a few simpler ones sor readability.

I have sometimes used MatchEvaluator delegate. A MatchEvaluator as an event handler that fires when an "OnMatch" event occures. Gives a little stucture to your regex.
And don't try that assignment with a subpattern

A subpattern is name on something that has matched. Changing what is matching just don't make any sense. Assign it to a c# variable if you need to do something with it outside the regular expression match.

Oh my, I should have made that clearer  I guess I am using the term "subexpression" wrong.
What I would like to see is basically an advanced defiition:
something := [a-zA-Z_][a-zA-Z_0-9]
so that I can use something instead of the sequence on the rhs. (They should match different strings, and I am not looking for a replace - just a match and split into components)

hmm I see. No, you can not have something instead of rhs!

I am not sure about hotmail's free POP3 support. Search for some articles explaining how to create a POP3 client. Look at the Post office protocol's RFC for getting an idea on how it works.

Google turned up this[^] for the hotmail issue as they disallowed POP3 and normal IMAP access quite a while ago.

I have a nested repeater that I am trying to sum totals entered by a user, the code behind and repeater code is below. I get a null reference exception: an object reference not set to an instance of an object. the error is at: (((TextBox)parent.FindControl("TextBox2")).Text) = Convert.ToString(compPercent);
How can I get to this control to update, or add a label here?
public void AddComponent(object sender, EventArgs e)
{
int compPercent = 0;
foreach (RepeaterItem repItm in parent.Items)
{
foreach (Control childControl in repItm.Controls)
{
Repeater childRepeater = childControl as Repeater;
if (childRepeater != null)
{
foreach (RepeaterItem child in childRepeater.Items)
{
foreach (Control childControl2 in child.Controls)
{
CheckBox chk = childControl2 as CheckBox;
if (chk != null)
{
if (chk.Checked)
{
//get percent entered
compPercent = compPercent + Convert.ToInt32(((TextBox)child.FindControl("capabilitiesPercentEntered")).Text);
(((TextBox)parent.FindControl("TextBox2")).Text) = Convert.ToString(compPercent);
}
}
}
}
}
}
}
}

Try putting your code in <code></code> blocks, and it will be easier for people to read.

How does one issue an MS-DOS command from a C# program? I want to write a program that issues a command in every sub-directory from a specified directory.
This is written as a Windows application, not a console application.
Thank you,
Glenn

Given the following class hierarchy:
public class A
{
public virtual void func();
}
public class B : A
{
public override void func();
}
public class C : B
{
public override void func()
{
base.func();
}
}
How can my class C, call the func() implementation in the base class A.
In C++ this could be done by simply specifying the name of the base class, A::func(), but how can I do this in C#?
Thanks for your help.
