Although it does make things tougher on the programmer and can degrade performance, a component without a type library can still be used in VB. The following limitations apply to components without type libraries: You cannot add the component with the References dialog box. You cannot use the early binding method of creating object references from classes in the component. Instead you will need to use the slower late binding method as discussed in the "Creating the Object Reference and Binding" section.Your client cannot respond to events raised by the component. You cannot use the IntelliSense feature of VB with objects created from classes in the component. You cannot use the Object Browser dialog box to look up the class and member definitions in the object.
