IWMSContext Object (Visual Basic .NET)

The IWMSContext object provides methods for retrieving, adding, or updating a context. A context is an unordered list of name-value pairs. Each name can be used only once, and each value has exactly one data type. The methods in the following table enable you to specify and retrieve values based on their data type. You retrieve values from a public context by using a predefined member of the WMSDefines class and an associated key. The server resolves the class member to a reference to the name of the property, and it uses the key to speed the search for the property value. Typically, a key is made up of the class member followed by _ID. If you do not use a key, it is recommended that you specify WMS_NO_NAME_HINT, which is defined in the WMS_CONTEXT_HINT_CONSTANTS enumeration type.

Note   This object is available only on Windows Server 2003, Enterprise Edition; Windows Server 2003, Datacenter Edition; and Windows Server 2008.
