One of the advantages of IntraWeb is that it uses the same kinds of tools and techniques as regular VCL development. You can build your user interface by dropping components on forms, like you would any other application. There are a number of important differences that you must keep in mind, however. The forms and components used in IntraWeb user interfaces are not the same ones used in non-Web GUI applications. When you create a form or use a component, be sure to use an IntraWeb version instead of a VCL version. 

Many VCL components have IntraWeb counterparts. Generally, the IntraWeb components have the same name as their VCL counterparts, with the letters "IW" prefixed to the name. For example, IWCheckBox is the IntraWeb equivalent of CheckBox. (The name used in source code starts with the letter T, of course, like TIWCheckBox.) On the Tool palette, the icons for IntraWeb components are nearly identical to their VCL counterparts, making it easier to find the IntraWeb components you need. 

The following table lists VCL components and their IntraWeb counterparts. For more information on these components and how to use them, refer to the IntraWeb help files and other IntraWeb documentation.
