MyNewString = StrConv(MyString, vbProperCase)

Method 2 – convert to character array to freely manipulate each letter. This has the advantage of over-riding the caps lock but only capitalises the first letter of the first word.

Method 3 – use a TextInfo object which has a ToTitleCase method. This has thye advantage of capitalising thye first letter of each separate word but is over-ridden by caps lock. (This method requires using System.Globalization and System.Threading.

Here is the code for methods 2 and 3

private void textBox1_TextChanged(object sender, EventArgs e)
        {
            char[] c = textBox1.Text.ToCharArray();
            int j;
            for (j = 0;j<textBox1.Text.Length;j++) {
                if (j==0) c[j]=c[j].ToString().ToUpper()[0];
                else c[j] = c[j].ToString().ToLower()[0];
            }
            textBox1.Text = new string(c);
            textBox1.Select(textBox1.Text.Length,1);
            }

        private void textBox2_TextChanged(object sender, EventArgs e)
        {
            CultureInfo cI = Thread.CurrentThread.CurrentCulture;
            TextInfo textInfo = cI.TextInfo;
            textBox2.Text = textInfo.ToTitleCase(textBox2.Text);
            textBox2.Select(textBox2.Text.Length, 1);
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {
            if ((textBox1.Text.Length) == 1)
            {
                textBox1.Text = textBox1.Text[0].ToString().ToUpper();
                textBox1.Select(2, 1);
               
            }
        }
