How do i make a textbox that uses different forecolors?

  Yes, you can do this pretty easily with the RichTextBox control. You can find a list of documentation at: http://msdn.microsoft.com/library/default.asp url=/library/en-us/vbcon/html/vboririchtextboxctltasks.asp

   

  Hope this helps,

  Here's something that will work, it's not perfect as it doesn't differentiate between portions of words (E.g. World and Worldwide) but it may drive you closer to your goal.

   

  private void HighLightWord( string Word, Color TheColor ) {

  // Locals

  int lastfound = 0;

  // Flip case

  Word = Word.ToUpper();

  if (this.richTextBox1.Text.ToUpper().Contains(Word))

  {

  while (richTextBox1.Text.ToUpper().IndexOf(Word, lastfound) != -1)

  {

  // Find text (you must ignore case since IndexOf is case sensitive

  int Index = richTextBox1.Text.ToUpper().IndexOf(Word, lastfound);

  // Set to new color

  richTextBox1.Select(Index, Word.Length);

  richTextBox1.SelectionColor = TheColor;

  // Increment

  lastfound = Index + 1;

  }

  }

  }

  private void richTextBox1_TextChanged(object sender, EventArgs e)

  {

  // Save the current selection

  int currentStart = richTextBox1.SelectionStart;

  int currentLength = richTextBox1.SelectionLength;

  // Change all to black

  richTextBox1.Select(0, richTextBox1.TextLength);

  richTextBox1.SelectionColor = Color.Black;

  // Now colorise

  HighLightWord("Test", Color.Red);

  HighLightWord("Hello", Color.Blue);

  HighLightWord("World", Color.Green);

  // Restore current seleciton

  richTextBox1.Select(currentStart, currentLength);

   

  }

  mmm...

  i tried using the select and selectcolor methods,

  but it isnt worhking.

  i had something like this:

   

  public void HighLight(string Word, Color color)

  {

  if (this.richTextBox1.Text.Contains(Word)

  {

  int Index = richTextBox1.Text.IndexOf(Word, 0, 0);

  richTextBox.Select(Index, Word.Lenght);

  richTextBox.SelectionColor = color;

  }

  }
