SUMMARY
Moderate: Requires basic macro, coding, and interoperability skills.
This article describes a sample, user-defined function named

This article assumes that you are familiar with Visual Basic for
Applications and with creating Microsoft Access applications using the
programming tools provided with Microsoft Access. For more information
about Visual Basic for Applications, please refer to your version of the
"Building Applications with Microsoft Access" manual.
NOTE: Visual Basic for Applications is called Access Basic in Microsoft
Access versions 1.x and 2.0. For more information about Access Basic,
please refer to the "Introduction to Programming" manual in Microsoft
Access version 1.x or the "Building Applications" manual in Microsoft
Access version 2.0
NOTE: This article explains a technique demonstrated in the sample
files, RptSampl.exe (for Microsoft Access for Windows 95 version 7.0)
and RptSmp97.exe (for Microsoft Access 97). For information about how

- 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:
- Open the sample database Northwind.mdb (or NWIND.MDB in versions 1.x
and 2.0).
- 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])
- 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.
