Re: Showing the corresponding data from other text file after being sorted and searched other text file

that is exactly why I said you could create a class MyType that holds all info, then sort the collection of MyType objects; doing so keeps the items intact.

I have 5 text files and inside every file there are 30 predefined data. Is it possible for me to add those data in the class MyType as one? Besides that I have a function that lets the user add more data, which is easier to add in the class MyType as one.

if you can explain it properly, then you can program it.

This site will help you if you help yourself. You obviously have an internet connection so I would imagine you have access to a search engine such as google?

Hello
Please help me to show thousand seperator in textbox like: 25000000>25,000,000
I found a formul like below at textchanged event:

string myStr = textBox1.Text;<br />
TextBox1.Text = myStr.FormatString("#,###");

But it causes error at :

Int a = Convert.ToInt16(TextBox1.Text);

I want to seperate numbers in textbox anyway. I couldn't use "MaskedTextBox"

Please help me.
Regards

You could remove the "," before parsing (btw why aren't you using short.Parse?)

You can replace FormatString with ToString("N0"). And there are at least two problems with your parsing code. First of all, you convert TextBox1.Text to a 16-bit integer, then store it as a 32-bit integer. This constrains it to the value 65,535. That's far too small for the value you want.

Additionally, you're using Convert.ToInt16. Use the method int.Parse() instead.

Hi,

you can tell Parse and TryParse what it is you want to allow, e.g.:

int val;
bool OK=int.TryParse("12,345", NumberStyles.AllowThousands, null, out val);

Hello
Tanks for your help. I used your code like below :

Int64 val;<br />
bool ok;<br />
ok = Int64.TryParse(TextBox1.Text, NumberStyles.AllowThousands, null, out val);<br />
TextBox1.Text = Convert.ToInt64(val.ToString()).ToString("#,###");<br />

The problem accures after typing more than 4 numbers. Because cursor qoes to the left side of numbers, For example i want to type 12345, after typing 4 in typing 5 it TextBox shows : 51,234
Can you help me on this?

use this code:
by this code,your problem is ok

private void textBox1_TextChanged(object sender, EventArgs e)
       {
           try
           {
               string ss = textBox1.Text.Replace(",", "");
               int d = int.Parse(ss);
               string gg = String.Format("{0:###,###,###}", d);
               textBox1.Text = gg;


               textBox1.SelectionStart = textBox1.Text.Length;
           }
           catch
           {
           }

       }

try
{
string ss = textBox1.Text.Replace(",", "");
int d = int.Parse(ss);
string gg = String.Format("{0:###,###,###}", d);
textBox1.Text = gg;

textBox1.SelectionStart = textBox1.Text.Length;
}
catch
{
}

While reading the physical address of each card using WMI works, I've found it to be a little slow. If speed isn't your main concern, this is fine. However, if you want something slightly faster, then you could look into the NetworkInterface class

I'd use the NetworkInterface class over WMI.

Also, if you're going to use the MAC for some security related conern, make sure you're using the SAME MAC every time. It's possible the machine will have multiple network interfaces and will have multiple MAC's. Also, there are additional interfaces that will show up, even though there is no physical adapter for them!
