convert indian rupees from numbers to words

i want the money in numbers to be converted to words i.e in crores,lakhs,thousands,hundred.........
There is no built-in functionality for this in .NET. You will have to write your own logic based on If conditions and some maths.

Here's the logic needed, from a VB6 app.

Option Explicit

Private Sub Command1_Click()
Dim num As Long
Dim str As String
num = Val(Text1.Text)
str = convert(num)
MsgBox str
End Sub

Private Sub Form_Load()
Text1.Text = 1240
End Sub

Function convert(n As Long) As String
Dim s As String
Dim x As Integer
If n > 1000 Then
x = (n \ 1000)
s = sngl(x) & " Thousand"
n = n - (x * 1000)
End If
If n > 100 Then
x = (n \ 100)
s = s & sngl(x) & " Hundred "
n = n - (x * 100)
End If
If n > 10 Then
x = (n \ 10)
Select Case x
Case 2
s = s & "Twenty"
Case 3
s = s & "Thirty"
Case 4
s = s & "Fourty"
Case 5
s = s & "Fifty"
Case 6
s = s & "Sixty"
Case 7
s = s & "Seventy"
Case 8
s = s & "Eighty"
Case 9
s = s & "Ninety"
End Select
n = n - (x * 10)
End If
s = s & sngl(CInt(n))
If n = 0 Then s = "Zero"
convert = s
End Function

Function sngl(x As Integer) As String
Dim s As String
Select Case x
Case 1
s = s & " One"
Case 2
s = s & " Two"
Case 3
s = s & " Three"
Case 4
s = s & " Four"
Case 5
s = s & " Five"
Case 6
s = s & " Six"
Case 7
s = s & " Seven"
Case 8
s = s & " Eight"
Case 9
s = s & " Nine"
End Select
sngl = s
End Function
