IWMSNamedValues Interface

The IWMSNamedValues interface contains a collection of name-value pairs.

In addition to the methods inherited from IDispatch, the IWMSNamedValues interface exposes the following methods.

Method Description
Add Adds an IWMSNamedValue interface to the IWMSNamedValues collection.
get_Count Retrieves the number of name-value pairs contained in the IWMSNamedValues collection.
get_Item Retrieves a name-value pair from the IWMSNamedValues collection.
get_length Retrieves the number of name-value pairs contained in the IWMSNamedValues collection. This method is provided for JScript compatibility.
put_Item Inserts or modifies a name-value pair in the IWMSNamedValues collection.
Remove Removes a name-value pair from the IWMSNamedValues collection.

Example Code

The following example illustrates how to retrieve a pointer to an IWMSNamedValues interface.

#include <windows.h>
#include "wmsserver.h"

// Declare variables and interfaces.
IWMSServer      *pServer;
IWMSNamedValues *pNamedValues;

HRESULT         hr;

// Initialize the COM library and retrieve a pointer
// to an IWMSServer interface.
hr = CoInitialize(NULL);
hr = CoCreateInstance(CLSID_WMSServer,
                      NULL,
                      CLSCTX_ALL,
                      IID_IWMSServer,
                      (void **)&pServer);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to an IWMSNamedValues interface
// containing descriptive information about the server.
hr = pServer->get_Properties(&pNamedValues);
if (FAILED(hr)) goto EXIT;

System and custom plug-ins contain some default name-value pairs that can be accessed by simply indexing the name of the property you want to retrieve. For a list of the default values you can access, see Registering Plug-in Properties.

The following example illustrates how to retrieve one of the default configuration values.

// Declare variables and interfaces.
IWMSServer      *pServer;
IWMSPlugins     *pPlugins;
IWMSPlugin      *pPlugin;
IWMSNamedValues *pNamedValues;
IWMSNamedValue  *pNamedValue;

HRESULT         hr;
CComVariant     varIndex;
CComVariant     varValue;

// Retrieve a pointer to an IWMSPlugins interface
// containing event-handler plug-ins.
hr = pServer->get_EventHandlers(&pPlugins);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to an IWMSPlugin interface.
varIndex = "WMS IP Address Authorization";
hr = pPlugins->get_Item(varIndex, &pPlugin);
if (FAILED(hr)) goto EXIT;

// Retrieve a pointer to an IWMSNamedValues interface
// containing descriptive information about the plug-in.
hr = pPlugin->get_Properties(&pNamedValues);
if (FAILED(hr)) goto EXIT;

// Retrieve the default name-value pair
// describing the plug-in copyright.
varIndex = "Copyright";
hr = pNamedValues->get_Item(varIndex, &pNamedValue);
if (FAILED(hr)) goto EXIT;

// Retrieve the value associated with this pair.
hr = pNamedValue->get_Value(&varValue);
if (FAILED(hr)) goto EXIT;

EXIT:
    // TODO: Release temporary COM objects and uninitialize COM.
