I'm doing the hangman and every time the player hits a letter he has to change the letter by the line but I can not find a way to do it with a label, could it only be done in a textbox?
Thanks in advance!
For i = 0 To palabraAAcertar.Length - 1
If tbEscribirLetra.Text = palabraAAcertar(i) Then
'reemplazar caracter
End If
Next
You could do it using the Substring method, as you say:
For i = 0 To _palabraAAcertar.Length - 1
If tbEscribirLetra.Text = _palabraAAcertar(i) Then
labelResultado.Text =
labelResultado.Text.Substring(0, i) &
_palabraAAcertar(i) &
labelResultado.Text.Substring(i + 1)
End If
Next
The result is the concatenation of the text of the i characters first, the new character that will replace the line and the following characters to the index i .
You could also use a StringBuilder object:
Dim sb As New StringBuilder(labelResultado.Text)
For i = 0 To _palabraAAcertar.Length - 1
If tbEscribirLetra.Text = _palabraAAcertar(i) Then
sb(i) = tbEscribirLetra.Text
End If
Next
labelResultado.Text = sb.ToString()
You create a StringBuilder object with the initial text, you replace the characters of the indices indicated and you generate the resulting string with the ToString method.
