Convert a string to what type ?

[Pirate]

Is this what you want ?

Private Function Changeto(ByVal str As String) As String
        Dim ChangedStr As String = Nothing
        ChangedStr = Replace(str, "e", "3", 1, 3, CompareMethod.Text)
        MsgBox(ChangedStr)
    End Function
 
'Usage
Changeto("phear")
