Hi,

 Say I have a text box t1, and t1.Text = "this Is an Example".  How do I search through this string and convert only the first letter of each word to uppercase?  The resulting string should look like t1.Text="This Is An Example"

I am using C#

Your help is greatly appreciated!

A sample for converting a string to TitleCase can be found here: http://support.microsoft.com/kb/312890

1         private string UpperCaseSentence(string sRawInput)
2            {
3                if (string.IsNullOrEmpty(sRawInput))
4                {
5                    return string.Empty;
6                }
7                string[] sArrayInput = sRawInput.Split();
8                StringBuilder sBuilder = new StringBuilder();
9                for (int i = 0; i < sArrayInput.Length; i++)
10               {
11                   sBuilder.Append(UppercaseFirstLetter(sArrayInput[i]));
12                   sBuilder.Append(" ");
13               }
14               return sBuilder.ToString().TrimEnd();
15           }
16           public string UppercaseFirstLetter(string Input)
17           {
18               if (string.IsNullOrEmpty(Input))
19               {
20                   return string.Empty;
21               }
22               char[] stringChars = Input.ToCharArray();
23               stringChars[0] = char.ToUpper(stringChars[0]);
24               return new string(stringChars);
25           }

jeev Your Code is fine.

Try

    /// <summary>
    /// Lower case characters
    /// </summary>
    private const string FILTER_LOWER = "abcdefghijklmnopqrstuvwxyz";
    /// <summary>
    /// Upper Case Characters
    /// </summary>
    private const string FILTER_UPPER = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    /// <summary>
    /// Alpha (upper and lower) characters
    /// </summary>
    private const string FILTER_ALPHA = FILTER_LOWER + FILTER_UPPER;

    #region " Init... "
    /// <summary>
    /// Capitalise initial letters
    /// </summary>
    /// <param name="input">The input string</param>
    /// <returns>String with start of words capitalised</returns>
    public static string InitCaps(string input)
    {
      input = "" + input;
      StringBuilder output = new StringBuilder(input.Length);
      bool start = true;
      for (int i = 0; i < input.Length; i++)
      {
        string letter = input.Substring(i, 1);
        if (start && FILTER_ALPHA.Contains(letter))
        {
          output.Append(letter.ToUpper());
          start = false;
        }
        else
          output.Append(letter);
        if (letter == " ") start = true;
      }
      return output.ToString();
    }
    #endregion

 The unit tests I used were:

    /// <summary>
    /// Test InitCaps
    /// </summary>
    [Test]
    public void TestInitCaps()
    {
      this.TestInitCapsTest("", "", true);
      this.TestInitCapsTest(null, "", true);
      this.TestInitCapsTest("A123", "A123", true);
      this.TestInitCapsTest("a123", "A123", true);
      this.TestInitCapsTest("hello world", "Hello World", true);
    }

    #region " TestInitCapsTest           "
    /// <summary>
    /// Test FilterUserName
    /// </summary>
    /// <param name="sIn">Input string</param>
    /// <param name="sExpect">Expected output</param>
    /// <param name="bExpect">Expected Test result</param>
    private void TestInitCapsTest(string sIn, string sExpect, bool bExpect)
    {
      string sOutput = CommonData.InitCaps(sIn);
      if (sExpect != sOutput)
      {
        Console.WriteLine("sOutput:" + sOutput);
        Console.WriteLine("sExpect:" + sExpect);
      }
      Assert.AreEqual(sExpect, sOutput);
    }
    #endregion
