VB.Net Code to convert figures to strings

[mnmw]

Check out my VB.NET code to convert numbers entered in a text box to string....It converts upto 99999999 though.....

Imports vb = Microsoft.VisualBasic
Public Class frmFigures
    Private Function ConvertFigure(ByRef AmountInFigure As Double) As String
        If Trim(AmountInFigure) <> "" Then
            If AmountInFigure.ToString.Trim.Length = 1 Then
                ConvertFigure = getOnces(AmountInFigure)
            ElseIf AmountInFigure.ToString.Trim.Length = 2 Then
                If vb.Left(AmountInFigure.ToString.Trim, 1) = 1 Then
                    ConvertFigure = getTens(AmountInFigure)
                Else
                    ConvertFigure = getOtherTens(vb.Left(AmountInFigure.ToString.Trim, 1)) & " " & getOnces(vb.Right(AmountInFigure.ToString.Trim, 1)).ToLower
                End If
