Quick Review
URLs specify a protocol, a host, and an address in the following syntax: protocol://host/localname. The protocol defines how you fetch the object, host specifies the remote location of the object, and localname is a string that is passed to the local protocol handler at the remote location to resolve to a specific target on the remote location.
The CallTo syntax is an additional protocol that allows end users to enter a variety of forms of NetMeeting addresses.
The following table describes different uses of the CallTo URL in the NetMeeting SDK.
| Use | Description |
|---|---|
| Scripting | Use the CallTo method. |
| COM | Use the new NM_ADDR_CALLTO address mode. |
| UI ActiveX control | Use a CallTo URL in Your Web Page |
