What you are describing is so easy to program: what have you tried so far ?

The idea of having text-entry on one TabPage analyzed for vowels, and then the vowels shown on a click on a Label on another TabPage is very strange. What are your goals here; why are you using TabPages ?

Write this method on your .cs page

C#

public static string ExtractVowels(string text)
{
    // Note that this won't find upper-case vowels...
    var vowelArray = text.Where(c => "aeiou".Contains(c))
                         .ToArray();
    // Upper-case it if you want, of course.
    return new string(vowelArray);
}

call this method on Button click

C#

label1.Text=ExtractVowels(textbox1.text);

Thanks & Regard
Sham :)

C#

Char[] vowels = new char[] { 'a', 'e', 'i', 'o', 'u' };
            string str = textBox1.Text;
            string result = "";
            string r = "";
            char[] ch = str.ToCharArray();
            foreach (char c in ch)
            {
                if (vowels.Contains(c))
                {
                    result = c.ToString();
                    r = r + result;
                }

                else
                {
                    //consonant
                }
                label2.Text = radioButton2.Text + textBox1.Text + "Length is:" + textBox1.TextLength + "Vowels are : " + r;
