make a one function in which the data table or data set is bind into the grid view....
after updation call the function immediately... then you will get your updated grid view..
If You Get your answer then please Rating me...
Thanks..

hi........
the code is
con.ConnectionString = "Data Source=SPARK1\\SQLEXPRESS;Initial Catalog=Empdetails;Integrated security=true";
con.Open();
//int p = Convert.ToInt32(dataGridView1.SelectedRows);
String s = "Select * from Empdetails where EmpId=";
SqlCommand cmd = new SqlCommand(s, con);
SqlDataReader dr = cmd.ExecuteReader();
//dataGridView1.DataSource = dr;
//GridView1.DataBind();
while (dr.Read())
{
txtempid.Text = dr.GetInt32(0).ToString();
txtname.Text = dr.GetValue(1).ToString();
txtaddress.Text = dr.GetValue(2).ToString();
combodes.Text = dr.GetValue(3).ToString();
txtphno.Text = dr.GetInt32(4).ToString();
}
dr.Close();
cmd.ExecuteNonQuery();
con.Close();
}

a) You've posted code, but not formatted it. in <pre> tags
b) You haven't said what is or is not happening that needs to be fixed.Dalek Dave: There are many words that some find offensive, Homosexuality, Alcoholism, Religion, Visual Basic, Manchester United, Butter.

Congratulations! You win the prize for posting the most useless post of the day!
Exactly the same as the post you were criticised for, but missing one closing curly bracket!

Hi guyz.
I am writing a parental control system. This is a C#.NET executable ParentalController.exe and is started as System.Diagnostics.Process.Start. The app is working fine but i don't want the children to stop the ParentalController.exe from Task Manager. I have tried a solution in which another app (guard.exe) is guarding the ParentalController.exe but i dont like this solution theoritically because a clever child can stop both the executables. So i am looking for a solution in which the child just cannot stop the application and its guardian from Task Manager. However the administrator (Parent) can stop both executables.
I hope i have explained the problem properly. Please help me.
Thanks

If the ParentalController.exe is run under an Admin account, and the children are logged on as Users, they can't kill that process using Task Manager, right?

Thanks calla !
I am going to try your solution. But how to make a process run under admin account 
|
|
|
|
|
You could run it as a Windows Service and choose to run it under LOCAL SYSTEM.
If you start it using System.Diagnostics.Process.Start then use the signature that takes a user name and password as well.
Check this link[^] out.

Hi, yes initially it was a windows service but then i made it a simple executable. I am going to use the signature solution now. A big thank you to you....

Hi,
I have only been using C# for a few weeks now and have recently found the following code and adjusted it to read a text file on my PC. It appears to be working as it is printing all of the data as expected to the screen in the following format;
3869;
4758;
7890;
9943;
and so on;
I would like to ask what is the best way to find the nearest value within the .txt file that is above another value. Let's say in the case the value is 4991 then I would like to return the value of 7890 only.
{
readText = File.ReadAllText("C:\\PIn.txt");
string [] split = readText.Split(new Char [] {';'});
foreach (string s in split)
{
count++;
levels[count] = int.Parse(s);
}
Print(readText);
}
As a newbie I really appreciate the help so thank in advance,

When you read each value in your file, first check if the value you read is greater than the value you are interested in (in your example 4991). In case it is: calculate the difference between that number and 4991 and store the number and the result in memory in case it is the smallest difference so far. And just loop through all the numbers. In code something like this:
int num = 4991;
int tmp, res = 0;
int? diff = null;
foreach (string s in split)
{
count++;
tmp = int.Parse(s);
levels[count] = tmp;
if (tmp > num)
{
if (diff == null)
diff = num;
if ((tmp - num) < diff)
{
res = tmp;
diff = tmp - num;
}
}
}
Console.WriteLine(res);
Could probably be done in a better way, but you get the idea.
Good Luck!

Hi Everyone, I got a question,
I am very much fond of using
string fileContent = File.ReadAllText(fileName)
to read a file. But I found many programmers are using
StreamReader objReader = new StreamReader(fileName);
string fileContent = objReader.ReadToEnd();
objReader.Close();
So, my question, which option is better ? I mean, in what case, I should prefer to use StreamReader over File.ReadAllText() ?
|
|
|
|
|
File.ReadAllText internally makes use of a StreamReader, and is implemented like this:
public static string ReadAllText(string path, Encoding encoding)
{
using (StreamReader reader = new StreamReader(path, encoding))
{
return reader.ReadToEnd();
}
}
So the only real benefit is that it wraps the stream in a using statement and makes for simpler/smaller code.Scott Dorman Microsoft® MVP - Visual C# | MCPD

Hi Scott,
Thanks for your answer. I see, I did not know that ReadAllText just wraps the StreamReader. So, I can say that, instead of using ReadAllText, it is MORE EFFICIENT to use the StreamReader Directly, because, I can save a function call (1 Stack Operation) by embedding the code block in my codes, Right ?
|
|
|
|
|
That is ridiculous; reading the whole text file will takes orders of magnitude more cycles than performing a single method call, and hence the latter is completely irrelevant.
|
|
|
|
|
| To add to what Luc said, a single method call is pretty much irrelevant in the context of a ReadToEnd, but the fact that the wrapper includes the "using" statement to clean up resources isn't. It is too easy to forget that the resources are not immediately freed if you use the stream directly, so if you are reading multiple files, then ReadAllText can result in easier to read code that actually works better and more efficiently despite the additional method call!
