CWDataSocket
CWDataSocket is a component that can connect to various data sources for reading data or data targets for writing data. Sources and targets may be local (on the current machine) or on other machines in the office or over the Internet. CWDataSocket holds stores data in CWData objects, which you can access with the CWDataSocket.Data property.
