This is what happens when you think outside the square... private void button2_Click(object sender EventArgs e) { //put this in button click event FOR TESTING can be automated NO clicking involved. string number = te.Text tmp = ; //in this case te (textBox1) contains 11111 int n = -1 pos = -1; //n gets the last char from string which is NOT a 9 pos gets the position of n for (int i = te.Text.Length; i > 0; i--) { if (number[i-1].ToString() != 9) //char is NOT a 9 { n = int.Parse(number[i-1].ToString()); //assign number[n] to the (int) n value pos = i-1; //get the pos break; } } n++; //increment n by 1 for (int i = 0; i { if (i != pos) tmp += number[i].ToString(); //rebuild string value should be 1111 until pos of n else tmp += n.ToString(); //string value should now be 11112 after first increment of n } te.Text = tmp; } this method will work for 11111 or any other length of 1's this -> 11111111111111111111111 makes no difference..

Jaish- did you notice your code also only takes 40 clicks to reach goal.

Hi If your number 11111 moving towards the ultimate goal of 99999 Try below public partial class Form1 : Form { int initNumber = 11111; int increment = 0; private void button1_Click_1( object sender EventArgs e) { increment = increment + 1; if (increment { initNumber = initNumber + 1; } else if (increment { initNumber = initNumber + 10; } else if (increment { initNumber = initNumber + 100; } else if (increment { initNumber = initNumber + 1000; } else if (increment { initNumber = initNumber + 10000; } MessageBox .Show(initNumber.ToString()); } }

Hi - I created some code as you asked - after each number is incremented to 9 you only have 40 click events or 40 receipt numbers Add a buttontextbox and a label to a form and have a look. public partial class Form1 : Form { int [] mydigit = new int [5]; string strA  strB strC  strD  strE; int count = 0; public Form1() { InitializeComponent(); } private void Form1_Load( object sender EventArgs e) { loadTxt(); } void loadTxt() { mydigit[0] = 1; mydigit[1] = 1; mydigit[2] = 1; mydigit[3] = 1; mydigit[4] = 1; strA = Convert .ToString(mydigit[0]); strB = Convert .ToString(mydigit[1]); strC = Convert .ToString(mydigit[2]); strD = Convert .ToString(mydigit[3]); strE = Convert .ToString(mydigit[4]); textBox1.Text = (strA + strB + strC + strD + strE); } private void button1_Click( object sender EventArgs e) { increaseByOne(); count++; label1.Text = Convert .ToString(count); } private void increaseByOne() { if (mydigit[4] { mydigit[4] = mydigit[4] + 1; } else if (mydigit[3] { mydigit[3] = mydigit[3] + 1; } else if (mydigit[2] { mydigit[2] = mydigit[2] + 1; } else if (mydigit[1] { mydigit[1] = mydigit[1] + 1; } else if (mydigit[0] { mydigit[0] = mydigit[0] + 1; } strA = Convert .ToString(mydigit[0]); strB = Convert .ToString(mydigit[1]); strC = Convert .ToString(mydigit[2]); strD = Convert .ToString(mydigit[3]); strE = Convert .ToString(mydigit[4]); textBox1.Text = (strA + strB + strC + strD + strE); } }
