WNetDisconnectDialog

The WNetDisconnectDialog function starts a general browsing dialog box for disconnecting from network resources. 

DWORD WNetDisconnectDialog(
  HWND hwnd,     // handle to window owning dialog box
  DWORD dwType   // resource type to disconnect from
);

Parameters

hwnd
Identifies the owning window.
dwType
Specifies the resource type to disconnect from. This parameter may be one of the following values:
Value Meaning
RESOURCETYPE_DISK Disconnects from disk resources.
RESOURCETYPE_PRINT Disconnects from print resources.

Return Values

If the function succeeds, the return value is NO_ERROR. If the user cancels out of the dialog box, it is 0xFFFFFFFF.

If the function fails, the return value is an error code. To get extended error information, call GetLastError. GetLastError may return one of the following error codes:

Value Meaning
ERROR_EXTENDED_ERROR A network-specific error occurred. To get a description of the error, use the WNetGetLastError function.
ERROR_NO_NETWORK No network is present.
ERROR_NOT_ENOUGH_MEMORY There is insufficient memory to start the dialog box.

The function returns error codes for compatibility with Windows version 3.1. For compatibility with the Win32 API, the function also sets the error code value returned by GetLastError.

Remarks

If the user chooses OK in the dialog box, the requested network disconnections will have been performed when WNetDisconnectDialog returns.
