Issuing the REPLACE in the valid of your text box works great in a desktop application...even in an n-tier architecture. However, if you want to take it one step further and make it work in both a desktop and Internet application, you can add a "SetPrice()" method to the business object that accepts the price as a parameter and issues the REPLACE internally. This method can then be easily called from both a VFP UI as well as a Web app.
