NETRESOURCEA structure (winnetwk.h)

The following structure contains information about a network resource. It is used by several of the network provider functions, including NPOpenEnum and NPAddConnection.

Syntax

typedef struct _NETRESOURCEA {
  DWORD dwScope;
  DWORD dwType;
  DWORD dwDisplayType;
  DWORD dwUsage;
  LPSTR lpLocalName;
  LPSTR lpRemoteName;
  LPSTR lpComment;
  LPSTR lpProvider;
} NETRESOURCEA, *LPNETRESOURCEA;

Members

dwScope

Indicates the scope of the enumeration. This can be one of the following values.

Value Meaning
RESOURCE_CONNECTED
Current connections to network resources.
RESOURCE_GLOBALNET
All network resources. These may or may not be connected.
RESOURCE_CONTEXT
The network resources associated with the user's current and default network context. The meaning of this is provider-specific.

dwType

Indicates the resource type. This can be one of the following values.

Value Meaning
RESOURCETYPE_DISK
The resource is a shared disk volume.
RESOURCETYPE_PRINT
The resource is a shared printer.
RESOURCETYPE_ANY
The resource matches more than one type, for example, a container of both print and disk resources, or a resource which is neither print or disk.

dwDisplayType

Set by the provider to indicate what display type a user interface should use to represent this resource. The following types are defined.

Value Meaning
RESOURCEDISPLAYTYPE_NETWORK
The resource is a network provider.
RESOURCEDISPLAYTYPE_DOMAIN
The resource is a collection of servers.
RESOURCEDISPLAYTYPE_SERVER
The resource is a server.
RESOURCEDISPLAYTYPE_SHARE
The resource is a share point.
RESOURCEDISPLAYTYPE_DIRECTORY
The resource is a directory.
RESOURCEDISPLAYTYPE_GENERIC
The resource type is unspecified. This value is used by network providers that do not specify resource types.

dwUsage

A bitmask that indicates how you can enumerate information about the resource. It is defined only if dwScope is set to RESOURCE_GLOBALNET. The dwUsage field can contain one or more of the following flags.

Value Meaning
RESOURCEUSAGE_CONNECTABLE
You can connect to the resource by calling NPAddConnection. If dwType is RESOURCETYPE_DISK, then, after you have connected to the resource, you can use the file system APIs, such as FindFirstFile, and FindNextFile, to enumerate any files and directories the resource contains.
RESOURCEUSAGE_CONTAINER
The resource is a container for other resources that can be enumerated by means of the NPOpenEnum, NPEnumResource, and NPCloseEnum functions.

The container may, however, be empty at the time the enumeration is made. In other words, the first call to NPEnumResource may return WN_NO_MORE_ENTRIES.

lpLocalName

If dwScope is RESOURCE_CONNECTED, the lpLocalName field contains the name of a redirected device. If the connection is a deviceless connection, this field contains NULL.

If dwScope is not set to RESOURCE_CONNECTED, this field is undefined.

lpRemoteName

If the enumerated item is a network resource, this field contains a remote network name. This name may be then passed to NPAddConnection to make a network connection if dwUsage is set to RESOURCEUSAGE_CONNECTABLE. If the enumerated item is a current connection, this field will refer to the remote network name that lpLocalName is connected to.

lpComment

May be any provider-supplied comment associated with the enumerated item.

lpProvider

Specifies the name of the provider that owns this enumerated item.

Remarks

Note

The winnetwk.h header defines NETRESOURCE as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
