Functions

 
AddConnectNotify

Called before and after each add connection operation (WNetAddConnection, WNetAddConnection2, and WNetAddConnection3) is attempted by the Multiple Provider Router (MPR).
CancelConnectNotify

Calls CancelConnectNotify before and after each cancel connection operation (WNetCancelConnection and WNetCancelConnection2).
NPAddConnection

Connects a local device to a network resource. (NPAddConnection)
NPAddConnection3

Connects a local device to a network resource. (NPAddConnection3)
NPCancelConnection

Disconnects a network connection.
NPCloseEnum

Closes an enumeration.
NPDeviceMode

Specifies the parent window of a device. This window owns any dialog boxes that originate from the device.
NPDirectoryNotify

Notifies the network provider of certain directory operations.
NPEnumResource

Performs an enumeration based on a handle returned by NPOpenEnum.
NPFMXEditPerm

Enables network vendors to supply their own permission editor dialog boxes.
NPFMXGetPermCaps

Retrieves the capabilities of the permission editor. The return value is a bitmask that indicates which of the Security menu items in File Manager are to be enabled.
NPFMXGetPermHelp

Retrieves the help file and help context of the permission editor dialog boxes when a menu item in the Security menu of File Manager is selected and F1 is pressed.
NPFormatNetworkName

Formats a network name in a provider-specific format for display in a control.
NPGetCaps

Returns information about which services are supported on the network.
NPGetConnection

Retrieves information about a connection.
NPGetConnection3

Retrieves information about a network connection, even if it is currently disconnected.
NPGetConnectionPerformance

Returns information about the expected performance of a connection used to access a network resource. The request can only be for a network resource that is currently connected.
NPGetDirectoryType

Determines the type of a network directory.
NPGetPropertyText

Retrieves the names of buttons to add to a property dialog box for a network resource.
NPGetResourceInformation

Separates the part of a network resource accessed through the WNet API from the part accessed through APIs specific to the resource type.
NPGetResourceParent

Retrieves the parent of a specified network resource in the browse hierarchy.
NPGetUniversalName

Retrieves the universal name of a network resource. The NPGetUniversalName function can retrieve this universal name in UNC format or in the older, remote-name format.
NPGetUser

Retrieves the value of the current default user name or the user name used to establish a network connection.
NPLogonNotify

MPR calls this function to notify the credential manager that a logon event has occurred, allowing the credential manager to return a logon script.
NPOpenEnum

Opens an enumeration of network resources or existing connections. The NPOpenEnum function must be called to obtain a valid handle for an enumeration.
NPPasswordChangeNotify

MPR calls this function to notify the credential manager of a password change event.
NPPropertyDialog

Called when the user clicks a button added by using the NPPropertyDialog function. The NPPropertyDialog function is called only for file and directory network properties.
NPSearchDialog

Enables network vendors to supply their own form of browsing and search, beyond the hierarchical view presented in the Connection dialog box.
WNetSetLastErrorA

Sets extended error information. Network providers should call this function instead of SetLastError. (ANSI)
WNetSetLastErrorW

Sets extended error information. Network providers should call this function instead of SetLastError. (Unicode)

Structures

 
NOTIFYADD

The NOTIFYADD structure contains the details of a network connect operation. It is used by the AddConnectNotify function.
NOTIFYCANCEL

The NOTIFYCANCEL structure contains the details of a network disconnect operation. It is used by the CancelConnectNotify function.
NOTIFYINFO

The NOTIFYINFO structure contains status information about a network connect or disconnect operation. It is used by the AddConnectNotify and CancelConnectNotify functions.
