ActiveX Controls Designed to work on the Internet, these controls are extensions of the older, stand-alone OLE controls -- i.e., controls based on object linking and embedding (OLE). Linking gives you a line to an object; embedding lets you have your own copy of the object. If you wish to maintain a reference, for instance, you can link to the reference, in which case you can always have an updated version of it (so long as the link remains intact). Or you can embed a copy of the reference and at least be assured of having that much should the link be broken. It is data not contained on this page, but you can access, if you choose.

Browser Control Inserted by Visual Basic Application Wizard into an application, this control provides simple and direct access to the Internet for any user who subscribes to an Internet service.

Internet Explorer (IE) Animated Button Animated display showing Internet Explorer's connections.

IE Popup Menu A menu control that appears on the Web page.

IE Preloader A control that preloads a page from a site before the visible Internet access begins.

IE Super Label A Web page label.

IE Timer Provides timing operations for Internet services.

Internet Transfer Control (MSINET.OCX) By means of its properties, methods, and events, this control provides the functionality to access data in three standard Internet protocols, namely the Hypertext Transfer Protocol (HTTP), Secure HTTP, and the File Transfer Protocol (FTP).

Winsock Control (WSWINSCK.OCX) By means of its properties, methods, and events, Winsock provides Visual Basic applications with direct access to the Windows Applications Programming Interface (API). Lying behind the "wall," as part of the Windows operating system, is a collection of thousands of specialty programs that an application can use -- you can think of them as subroutines, though they're not part of the applications. The control defines the interface by means of which Windows applications would program the Transfer Control Protocol (TCP) and the User Datagram Protocol (UDP). It is a wrapper that calls the Winsock API for you.

AsyncReadComplete Notifies your program that a particular asynchronous download has been completed. 

AsyncRead Begins a download operation.

CancelAsyncRead Cancels an asynchronous download operation that's in progress

CoGetClassObject Calls a class object, as part of the Internet Component Download service.

CoGetClassObjectFromURL A COM -- Component Object Model -- function called by Microsoft's Internet Explorer whenever the <OBJECT> tag is encountered in an HTML document. Takes a URL (Uniform Resource Locator) and returns an instance of the specified object.

DLLRegisterServer() Used for .DLLs and .OCXs when registering ActiveX components in an Internet download. (DLLs, for dynamic link libraries, are the API-based routines that are available for use by (VB or other) applications. OCXs are ActiveX controls.)

WinVerifyTrust Ensures that all downloaded files are safe to install. 

AsyncProperty An object with three properties, namely AsyncType, PropertyName, and Value, the first two of which are the same values that are passed to the AsyncRead method when the download begins  The third contains the data that's actually downloaded.

Hyperlink A property of UserControl, this object gives your control access to the hyperlinking functionality, namely the ability to jump to a given URL (or step through a history list).

UserControl A container in which ActiveX controls are built -- analogous to a form used for ordinary controls.

UserDocument An object indistinguishable from an ordinary form that's used in the creation of an ActiveX document.
