MORE INFORMATION

To create the ConvertCurrencyToEnglish() function, follow these steps:

1. Create a new module and type the following line in the Declarations

   section if the line is not already there:

      Option Explicit

2. Type the following four procedures:

      Function ConvertCurrencyToEnglish (ByVal MyNumber)
         Dim Temp
         Dim Dollars, Cents
         Dim DecimalPlace, Count

         ReDim Place(9) As String
         Place(2) = " Thousand "
         Place(3) = " Million "
         Place(4) = " Billion "
         Place(5) = " Trillion "

         ' Convert MyNumber to a string, trimming extra spaces.
         MyNumber = Trim(Str(MyNumber))

         ' Find decimal place.
         DecimalPlace = InStr(MyNumber, ".")

         ' If we find decimal place...
         If DecimalPlace > 0 Then
            ' Convert cents
            Temp = Left(Mid(MyNumber, DecimalPlace + 1) & "00", 2)
            Cents = ConvertTens(Temp)

            ' Strip off cents from remainder to convert.
            MyNumber = Trim(Left(MyNumber, DecimalPlace - 1))
         End If

         Count = 1
         Do While MyNumber <> ""
            ' Convert last 3 digits of MyNumber to English dollars.
            Temp = ConvertHundreds(Right(MyNumber, 3))
            If Temp <> "" Then Dollars = Temp & Place(Count) & Dollars
            If Len(MyNumber) > 3 Then
               ' Remove last 3 converted digits from MyNumber.
               MyNumber = Left(MyNumber, Len(MyNumber) - 3)
            Else
               MyNumber = ""
            End If
            Count = Count + 1

         End Select
      End Function

3. To test this function, type the following line in the Debug window

   (or Immediate window in version 1.x and 2.0), and then press ENTER:

      ? ConvertCurrencyToEnglish(1234.56)

How to Use the ConvertCurrencyToEnglish() Function on a Form

To demonstrate the use of the ConvertCurrencyToEnglish function on a form, follow these steps:

1. Open the sample database Northwind.mdb (or NWIND.MDB in versions 1.x

   and 2.0).

2. Open the Orders form in Design view and add a text box to the form.

   Set the text box's ControlSource property as follows:

      =ConvertCurrencyToEnglish([Total])

3. Open the Orders form in Form view. Note that the text box displays an

   English word representation of the total order amount computed in the
   form's Total field.
