how to increment textbox value

Yucel Emir

I have a form where I define code masks in a masked textbox, for example CA##### and assign it to a textbox that I am using as the code of relevant form. ( Current Account Code = CA0001).

How can I increment the value automatically?

automatic increment isn't possible only if you create a new class - consisting a string and a integer. Now you can overload the increment-operator! Example:

class SplitString...
{
   string s;
   int i;
   public bool operator ++(SplitString s)
   {
      i++;
   }
   public SplitString(string str)
   { ...split str to a string and an integer...}
}
now you can create a object SplitString x, then execute x++;

If your string CAR00001 is always in fixed format then split sting as below and increment integer part

string str= textBox1.Text;
string intPart= str.Substring (3,5);
int nextValue=Convert.ToInt32(intPart)+1;
textBox1.Text="CAR"+ nextValue.ToString("0000");

If it helps you select it as correct answer.

Don't use static value using coding. because every time when application restarted. You counter start from initial value. So it may be case of duplicate value.

create a new string,
check each char from the old string, if consisting of numbers, add to the new string
now, you can use Convert.ToDouble(newString) and you have a number

Hey,

Try this

private void AutoIncrement()
{
var str = Label1.Text;
var tempArray = str.Split('/');
string tempId = tempArray[2];
int id = Convert.ToInt32(tempId);
id = id + 1;
string autoId ="QIEpl/PO/" + String.Format("{0:0000000}", id);
Label1.Text = autoId;
}

public partial class Form1 : Form { static int billno=2000; string code; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) {         billno = billno + 1;         textBox1.Text = billno.ToString(); }

}
