You probably want the filesystemwatcher, look into the IO namespace for it. Caveat, the early version choked on too many events but I have not used it since v1

is there any way to import CSV file to datagridview without all the procedure of connectionstrings and querys????? i want only to imports the parameters of the CSV to the table.....

You can read a CSV into memory as a string array using File.ReadAllLines and use the split method to split on the comma to get your fields.

What 
If you give us a proper example of what you want, we may be able to help you achieve it. Try to be a little clearer as the above makes no sense at all.

If I understand you, which I doubt
generate a VisibleChanged Event for your TextBox
private void aTextBox_VisibleChanged(object sender, EventArgs e)
{
aLabel.Visible = aTextBox.Visible;
}

Is there a function to call?
can anyone help me?

Maybe this article[^] can help?

Can I get the special xml strings (< & etc) directly instead of being translated?
For example, given the data "RCI>", the code:
xmlReader.ReadStartElement("DATA");
data = xmlReader.ReadString();
xmlReader.ReadEndElement();
Gives: "RCI>". Can I get the raw "RCI>" and if so, how?
Thanks

use
String.Replace Method

That's the one.
Thanks very much.

I have this code in my project:
<br />
string str;<br />
byte[] enc = new byte[str.length];<br />
enc = Convert.FromBase64String(str);<br />
when i trace it, in the 2nd line the enc is a byte with the length of str but when 3rd line executes the enc length becomes 1 and therefore my data is not valid at the end.
does anybody know what should i do?

You should know that the base64 encoding is a bit verbose.
I.e. Silly question, silly answer (i.e. please post input values, expected output, actual output if you want better help).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

You didn't assign any string to str.
What do you expect enc should be?
 *12Code
|
|
|
|
|
The assignment part of second line is not having any use. Your field will be having the return value from FromBase64String method.
Also the length of encrypted string and decrypted string wont be same.

How m i going to unit testing this kind of function?
plz help.
private void saverecord()
{
OleDbConnection savecon = new OleDbConnection(constring);
OleDbCommand savecom = new OleDbCommand("insert into Employee_Details values (?,?,?)", savecon);
OleDbParameter param;
param = savecom.Parameters.Add("@empcode", OleDbType.VarChar, 10);
param.Value = txtcode.Text;
param = savecom.Parameters.Add("@empname", OleDbType.VarChar, 25);
param.Value = txtname.Text;
param = savecom.Parameters.Add("@empjoin", OleDbType.Date);
param.Value = DateTime.Now.ToShortDateString();
savecon.Open();
int rows = savecom.ExecuteNonQuery();
MessageBox.Show(rows.ToString() + "rows affected");
btnref.PerformClick();
savecon.Close();
}
[TestMethod()]
public void saverecordTest()
{
Form1_Accessor target = new Form1_Accessor(); // TODO: Initialize to an appropriate value
target.saverecord();
//Assert.Inconclusive("A method that does not return a value cannot be verified.");
