Answer 1

you can use Regex for this

Imports System.Text.RegularExpressions 

then on some part of your code

Dim x As String = "123a123&*^*&^*&^*&^   a sdsdfsdf" MsgBox(Integer.Parse(Regex.Replace(x, "[^\d]", ""))) 

Answer 2

try this:

Dim mytext As String = "123a123" Dim myChars() As Char = mytext.ToCharArray() For Each ch As Char In myChars      If Char.IsDigit(ch) Then           MessageBox.Show(ch)      End If Next 

or:

Private Shared Function Num(ByVal value As String) As Integer     Dim returnVal As String = String.Empty     Dim collection As MatchCollection = Regex.Matches(value, "\d+")     For Each m As Match In collection         returnVal += m.ToString()     Next     Return Convert.ToInt32(returnVal) End Function
