Coding the CML User Interface

To run the Corporate Media Library (CML) application, a library user needs the following software:

• Microsoft® Internet Explorer version 4.0 or later. This includes an RDS ActiveX® control that the CML uses.
• A small, custom client-side COM component of the CML called UserInfo.
• The Microsoft Visual Basic® 6.0 run-time DLL. This is required to run the UserInfo component because UserInfo was compiled in Visual Basic.

The UserInfo component and the Visual Basic DLL (size: 1.6 MB) are packaged into a CAB file. When the CML application is first run, if the CMLC DLL is not detected as having been registered in the system registry, it is automatically downloaded from the Web server and installed to users' computers running Windows®. (For non-Windows systems, see Future Enhancements.) After this download, the user's computer must be rebooted. For more detail, see Instantiating the UserInfo Object; for an overview of this process, see Deployment.
