WNetDisconnectDialog

This function brings up a general dialog for disconnecting from network resources. When the dialog attempts to disconnect and an NP returns WN_OPEN_FILES, it prompts the user for confirmation.

DWORD WNetDisconnectDialog (
    HWND hwnd,
    DWORD dwType
    );

hwnd

This specifies the HWND of the owning window.

dwType

Used to specify the type of resources of interest. This must be one of:

RESOURCETYPE_DISK	Connect to disk resources.
RESOURCETYPE_PRINT	Connect to print resources.

WN_SUCCESS if the call is successful in bringing up the dialog. Other error codes include the following. Typically this dialog will only return an error if the dialog could not be brought up since errors that occur thereafter are reported to the user directly.

WN_FUNCTION_BUSY	The MPR or NP is busy (possibly initializing). The caller should retry.
WN_NO_NETWORK	network is not present.
WN_OUT_OF_MEMORY	insufficient memory to bring up the dialog.
WN_EXTENDED_ERROR	a network specific error occurred. WNetGetLastError should be called to obtain a description of the error.
