HI ,
I am developing a small application in which C# reads a file make changes to it and saves it.
The txt files contains dome configuration values say
TimeOut=30<br />
ID=abcd<br />
Scope=Allowed<br />
.<br />
.<br />
.<br />
1.In my screen i also want to show these values, so what is the method to fetch individual values
2.When i make any change to the value i want it to be saved in that particular line itself.
Thanks in Advance.

Why are you using an ini file and not XML ?

I'm not saying that INI files are the be all and end all of config files, but they are a *lot* easier for novice users to edit, compared to XML files.

You can read the values into a dictionary like this:
Dictionary<string, string> values = new Dictionary<string, string>();
foreach (string line in File.ReadAllLines(fileName)) {
string[] data = line.Split('=');
if (data.Length == 2) values.Add(data[0], data[1]);
}
To read a value from the dictionary:
string id = values["ID"];

Files are not line based, so you can't change a single line in a file. It's possible to update the file from that line and forward, but it's complicated. Just rewrite the entire file.
Despite everything, the person most likely to be fooling you next is yourself.

Hi to all,
I am using .Net framework 1.1 and want to download files from FTP using C#. Anybody please help me to how to do this.

Use WebClient class and DownlodData method in that. Before you need to authenticate the server. There are tons of samples available online.

is there any way in Listview to set a column property like frozen property in Datagridview ?

No, there isn't.
You'd have to write your own implementation of the ListView control to expose the properties required and provide all the drawing code to do this.
Or, you might want to try and find a 3rd party library that gives you such functionality. I don't know of any that do this.

| and & perform a bitwise operation, while || and && perform logical operations.
Also, the evaluation of || and && expressions is aborted once the result is certain, while | and & takes every operand into consideration.

Well, just use them as what they are meant for.
| and & for bitwise operation, much like + and /.
|| and && for logic operation, to make condition decision, or to get a true/false value, generally.
Most of the time, the result is the same, but the process where the result is resolved is different. Logic operation will be short-circuited by compiler, and I believe it is faster to be execute by CPU (correct me if I am wrong), because they are basically compare and jump operations.
If you use the bitwise operators instead of the logic operators, each and every one of the bitwise operators are to be evaluated, and under some situation, you may not get the same outcome:
obj= null;
a) if(obj != null && obj.ToString().Length > 0)
b) if(obj != null & obj.ToString().Length > 0)
Case b) will throw an exception because all of the statements in the if have to be evaluated.

| and & are bitwise operands. They can also be used as conditional operands (is that the right word?). The difference is easiest to explain with an example.
int x = 3; int y = 7;
if(x == 3 || y == 9)
Console.Writeline("Good to go.");
if(x == 3 | y == 9)
Console.Writeline("Good to go.");
In both cases "Good to go." is printed to the console. In the first case when x == 3 is evaluated to true, the body of the if statement is executed. In the second case x == 3 is evaluated to true and then y == 9 is also evaluated to true.
& works the same way:
int x = 3; int y = 7;
if(x == 4 && y == 9)
Console.Writeline("Good to go.");
if(x == 4 & y == 9)
Console.Writeline("Good to go.");
Once again in the first case, y == 9 is not evaluated. In the second case y == 9 is evaluated. In neither case is "Good to go." printed.
Does this make sense?

buddies, i know how they works, you misunderstood my question, i asked that why we uses | instead of ||, because || is better than | and output always same
e.g.
if (bool1 == true | bool2 == true)
// execute code
if (bool1 == true || bool2 == true)
// execute code
in above code both result will be same, but in first it will check both conditions however in second it will check first condition, if it false then check another else not
so why we uses | to decrease our performance?

| and & are not intended for use as logical operators although they can be (ab)used as such. They're intended for bitwise operations.
x = 6 | 3; <br />
<br />
x = 6 & 3; <br />
Otherwise [Microsoft is] toast in the long term no matter how much money they've got. They would be already if the Linux community didn't have it's head so firmly up it's own command line buffer that it looks like taking 15 years to find the desktop.

You only use | and & when you want both conditionals to be evaluated. Here is a somewhat crass example:
if(amanda.AttemptKiss() & sarah.AttempKiss())
Console.WriteLine("I'm back at university");
Even if you fail to kiss Amanda, you still want to try to kiss Sarah.

hehe, example of kisses

You should also check
if ( amanda.AttemptKiss ( sarah ) )
I would also consider having individual variables for containing individual references as too limiting and would instead use a Queue<Girls>.
|
|
|
|
|
To be pedantic.
<br />
Queue<girl> girls = new Queue<girl>();<br />
PopulateFromBar(girls);<br />
foreach(Girl g in girls){<br />
try {<br />
Drink d = bar.GetDrink();<br />
this.AttemptFlirt(g);<br />
g.Imbibe(d);<br />
this.AttemptKiss(g);<br />
this.CopAFeel(g);<br />
this.InviteHome(g);<br />
this.AddCompanion(g);<br />
this.Successes++;<br />
break;<br />
} catch(SlapException e) {<br />
this.AvoidList.Add(e.Girl);<br />
this.Drink(bar.GetDrink());<br />
} catch (RejectionException e) {<br />
this.Drink(bar.GetDrink());<br />
}<br />
}<br />
<br />
this.Travel(this.Home);<br />
</girl></girl>
For me, Successes is without a doubt a signed short. Can you get smaller than a short? I suppose we want a ridiculously large number that will never be reached in the future (*cough*640k*cough*), so that will do

But don't let them know you have only a short.
if ( g.HasFriend )
{
this.WingMan.Add ( g.Friend ) ;
}
And try not to use break in a foreach, in fact why foreach a queue?

I am quite new to C# and I think this is a really easy fix...I just can't find it. I am creating a GUI calculator for my class and am slowly learning the language MS Visual Studio 2008. [I started on Java]
My main question is:
I created some buttons, a menu, and text fields in the design part of the program, but when I try to run the program to test it, all these widgets are disabled. I checked the properties value and “Enabled = true”. Is it because I have not bound a handler to them yet?
I am also not sure if I need to put something else in the method handler. Here is my = method. Do I need to use the sender/e parameters elsewhere or is that done by the language/IDE?
private void buttonEnter_Click(object sender, EventArgs e)<br />
{<br />
di = Double.Parse(inputImaginary.Text);<br />
c = Double.Parse(inputReal.Text);<br />
<br />
a = printReal; bi = printImaginary;<br />
<br />
switch (operatorSymbol)<br />
{<br />
case '+': addition(c, di); break;<br />
case '-': subtraction(c, di); break;<br />
case '*': multiplication(c, di); break;<br />
case '/': division(c, di); break;<br />
case '=': printReal = c; printImaginary = di; break;<br />
default: break;<br />
}<br />
<br />
outputImaginary.Text = printImaginary.ToString();<br />
outputReal.Text = printReal.ToString();<br />
}
Thank you very much for your time and help. I think next time I am just going to hand code the GUI.

First, Visual Studio is an IDE, not a language.
Did you double click on the button in design mode to create the event handler, or did you just type in the code? Search your solution to see if you've set the event handler - it should look like this:
this.buttonEnter.Click += new System.EventHandler(this.buttonEnter_Click);
You can set breakpoints to see if the handler is being executed.
Cheers,
Vikram.
