Hello!

What I want is that, for each time that : 1,2,3,4 loop it will ad a number before, like its counting but it stops at 4. so: 1,2,3,4,11,12,13,14,21,22,23,24,31,32,33,34,41,42,43,44,111,112,113,114,121,122,123,124,131,132,133, 134,141,142,143,144,211........
just like counting but with 4 numbers instead of 9.

And i want it to work like this, for each time that i press the button i want it to show a new number.

String[] text = { "1", "2", "3", "4" };
        int count = 0;

        private void button1_Click(object sender, EventArgs e)
        {
            if (count == text.Length)
            {
                count = 0;
                
            }
            label1.Text = text[(count % text.Length)];
            count++;

        }

Thank you!

If our answers didn't work, what do you want to do then? Insert it somewhere in the middle?

Can you explain what you want your label1 to show? The expression "count % text.Length" always equals "count" AFAICS.

Answer updated again - sorry there appears to be a problem with the site, emails aren't working. It has been reported and will be fixed soon (I hope).

Obviously you can't use the SelectionStart property.
The Insert should work though, it's a String method.

Why not simply

label1.Text = "labe" + label1.Text;

?

Did you see this : Convert to any base[^]

Change your array to

string quat = IntToString(42, 
            new char[] { '0', '1', '2', '3', '4' };

Put this function in your code :

public static string IntToString(int value, char[] baseChars)
{
    string result = string.Empty;
    int targetBase = baseChars.Length;

    do
    {
        result = baseChars[value % targetBase] + result;
        value = value / targetBase;
    }
    while (value > 0);

    return result;
}

Now rewrite your function :

private void button1_Click(object sender, EventArgs e)
{
    label1.Text = IntToString(count, quat);
    count++;

}

Close enough, not tested but about right :)

Did you look at his numbers? He has no zero! :laugh:

Yes, I saw that, not really logical, I thought I'd better do it right :)

Why not just go:

myLabel.Text = "My new text: " + myLabel.Text;

"No, actually i found out that it doesn't work!... for my thing - euhiemf 31 mins ago"

So why not? What "doesn't work"?

String[] text = { "1", "2", "3", "4" }; int count = 0; private void button1_Click(object sender, EventArgs e) { if (count == text.Length) { count = 0; } label1.Text = text[(count % text.Length)]; count++; }

Ok, so it's a code fragment. It appears to have nothing to do with your question.
Your fragment just sets a label text to a different value each time a button is pressed. If it isn't intended to do that, what is it meant to do? :laugh:
"what i want is that for each time that : 1,2,3,4 loop it will ad a number before, like its counting but it stops at 4. so: 1,2,3,4,11,12,13,14,21,22,23,24,31,32,33,34,41,42,43,44,111,112,113,114,121,122,123,124,131,132,133, 134,141,142,143,144,211........ just like counting but with 4 numbers instead of 9. ;) - euhiemf 25 mins ago"

Oh, is that all:
You can't do that quite so simply, you have no zero to play with! So. it gets a bit complex...

C#

int[] currentValue = new int[3] { 0, 0, 0 };
private void button1_Click(object sender, EventArgs e)
    {
    for (int i = 0; i < currentValue.Length; i++)
        {
        if (currentValue[i] != 4)
            {
            currentValue[i]++;
            break;      // No need to move next digit.
            }
        else
            {
            // Move the next highest digit.
            currentValue[i] = 1;
            }
        }
    string s = "";
    for (int i = currentValue.Length - 1; i >=0; i--)
        {
        s += currentValue[i].ToString();
        }
    label1.Text = s;

This only handles three quadits (Can't call then digits, the "dig" comes from base ten) and the first press will set the label to "001", but I have to leave you some work!
