Textbox numbers values
-
Hi everyone, I have a textbox which holds numbers like e.g., xxxxxx I wonder how to change that value entered by the user to xx-xx-xx. I'm trying several regular expressions like: OpNumbers.Replace(OpNumbers, "^(\d{6}|(\d{2}-\d{2}-\{2}))$") and also : Format(lblOPReferenceNumber.Text.Trim, "## - ## - ##"). I'm not getting the output that need it. I'm pretty sure that I might be doing something wrong at some point. Thank you for you help. Venecos

Do you need leading zeros? Then you must use "0" instead of "#".
Dim number as int = int.Parse(textbox1.Text)
Dim result as string = number.ToString("00 - 00 - 00")
'without leading zeros:
Dim result2 as string = number.ToString("## - ## - ##") -

Alternatively, if you want to show the user the fomatted text, the
MaskedTextBoxcontrol withMaskproperty set as below may be usedMaskTextBox1.Mask = "00 - 00 - 00"
maskedTextBox1.TextMaskFormat = MaskFormat.IncludePromptAndLiterals
string maskedText = maskedTextBox1.Text
'Replace the blank characters
maskedText = maskedText.Replace("_","0")The mask characters are explained here http://msdn.microsoft.com/en-us/library/system.windows.forms.maskedtextbox.mask.aspx[^]
