Is there a way to use the Replace method in VB to replace a whole word?

CODE

word = InputBox("Enter a word:", "Hangman Game") 'User inputs word

' display dashes in the wordLabel
        ' and clear the incorrectLabel
        If word.Length = 3 Then
            wordLabel.Text = "---"
        ElseIf word.Length = 4 Then
            wordLabel.Text = "----"
        ElseIf word.Length = 5 Then
            wordLabel.Text = "-----"
        ElseIf word.Length = 6 Then
            wordLabel.Text = "------"
        ElseIf word.Length = 7 Then
            wordLabel.Text = "-------"
        End If


I want to be able to put a certain amount of dashes in the wordlabel box according to how many characters are put into the word inputbox instead of making If... Then statements like the ones shown. I have only found a way to use the replace method to replace a single letter.

Mod Edit: Please use code blocks, makes it easier to read smile.gif ==> code.gif

If this is .NET you could use

CODE

wordLabel.text = new String("-",word.length)


This will set the label to the number of dashes that is the same length of the word.

Enjoy!

The best, and most efficient way, I can think of would be to turn the text in the TextBox into a char array, then loop through the array replacing each char with a "-", something like this:

CODE

Private Sub ReplaceText()
     'Create a Char Array to hold the items in the text box
      Dim items() As Char = TextBox1.Text.ToCharArray()
     'Empty the textbox
      TextBox1.Text = String.Empty
      'Loop through each char in the array
      'and replace it with a "-"
       For Each ch As Char In items
           TextBox1.Text += "-"
       Next
End Sub


Something like this should help you. You could also use the PasswordChar property of the TextBox control to have it do this for you. So the choice is really up to you.

Hope this helps smile.gif
