The WNetAddConnection function enables the calling application to connect a local device to a network resource. A successful connection is persistent, meaning that Windows automatically restores the connection during subsequent logon operations.
This function is provided for compatibility with earlier versions of Microsoft Windows. For new applications, use the WNetAddConnection2 function.
DWORD WNetAddConnection(
LPTSTR lpRemoteName, |
// pointer to network device name |
LPTSTR lpPassword, |
// pointer to password |
LPTSTR lpLocalName |
// pointer to local device name |
); |
If this parameter is NULL, the default password is used. If the string is
empty, no password is used.
If the function succeeds, the return value is NO_ERROR.
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_ACCESS_DENIED |
Access is denied. |
ERROR_ALREADY_ASSIGNED |
The device specified in the lpLocalName parameter is already connected. |
ERROR_BAD_DEV_TYPE |
The device type and the resource type do not match. |
ERROR_BAD_DEVICE |
The value specified in lpLocalName is invalid. |
ERROR_BAD_NET_NAME |
The value specified in the lpRemoteName parameter is not valid or cannot be located. |
ERROR_BAD_PROFILE |
The user profile is in an incorrect format. |
ERROR_CANNOT_OPEN_PROFILE |
The system is unable to open the user profile to process persistent connections. |
ERROR_DEVICE_ALREADY_REMEMBERED |
An entry for the device specified in lpLocalName is already in the user profile. |
ERROR_EXTENDED_ERROR |
A network-specific error occurred. To get a description of the error, use the WNetGetLastError function. |
ERROR_INVALID_PASSWORD |
The specified password is invalid. |
ERROR_NO_NET_OR_BAD_PATH |
The operation cannot be performed because either a network component is not started or the specified name cannot be used. |
ERROR_NO_NETWORK |
The network is not present. |
The function returns error codes and sets the error code values returned by GetLastError.
