user_defined optional field

<i><b>Originally posted by : elecom (suimos@yahoo.com)</b></i><br /><br />hi,everyone <br />in asp/sql2000 applications people often find that the fields and tables provided can't meet their actual business situation so how can i not only provide user_defined optional fields or tables but also let user themself set dependencies with each other.<br />I know how to add , remove, rename a field. i want to go futher more .first i want to insert a field in a position exactly the user wishes in ie broswer. and second I want to design a administrator's backend interface allowing authrized user or administrators to define some fields or tables to meet their special business whitout having to modify program's soucecode reaptly?<br />For example, administrators can create a Products field that has a selection for each product their company develops and a Versions field that has a selection for each product version. they can set up dependencies for the Products field that tailor the selections available in the Versions field. When users select a product from the Products field, only applicable versions are available in the Versions field. In this case, the Products field is the<br />independent field and the Versions field is the dependent field. <br /><br />if anyone know the methods pls contact me <br />thanks for your kind<br />elecom<br />2002.7.29
