WNetAddConnection
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
| );
|
|
Parameters
lpRemoteName
Points to a null-terminated string that specifies the network resource to
connect to.
lpPassword
Points to a null-terminated string that specifies the password to be used to
make a connection. This parameter is usually the password associated with the
current user.
If this parameter is NULL, the default password is used. If the string is
empty, no password is used.
lpLocalName
Points to a null-terminated string that specifies the name of a local device
to be redirected, such as F: or LPT1. The case of the characters in the string
is not important. If the string is NULL, a connection to the network resource is
made without redirecting the local device.
Return Values
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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
