WNetGetConnection
The WNetGetConnection function retrieves the name of the network resource associated with a local
device.
DWORD WNetGetConnection(
LPCTSTR lpLocalName,
| // pointer to local name
| LPTSTR lpRemoteName,
| // pointer to buffer for remote name
| LPDWORD lpnLength
| // pointer to buffer size, in characters
| );
|
|
Parameters
lpLocalName
Points to a null-terminated string that specifies the name of the local device
to get the network name for.
lpRemoteName
Points to a buffer that receives the null-terminated remote name used to make
the connection.
lpnLength
Points to a variable that specifies the size, in characters, of the buffer
pointed to by the lpRemoteName parameter. If the function fails because the buffer is not big enough, this
parameter returns the required buffer size.
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_BAD_DEVICE
| The string pointed to by the lpLocalName parameter is invalid.
| ERROR_NOT_CONNECTED
| The device specified by lpLocalName is not redirected.
| ERROR_MORE_DATA
| The buffer is too small. The lpnLength parameter points to a variable that contains the required buffer size. More
entries are available with subsequent calls.
| ERROR_CONNECTION_UNAVAIL
| The device is not currently connected, but it is a persistent connection.
| ERROR_NO_NETWORK
| No network is present.
| ERROR_EXTENDED_ERROR
| A network-specific error occurred. To get a description of the error, use the WNetGetLastError function.
| ERROR_NO_NET_OR_BAD_PATH
| None of the providers recognized this local name as having a connection.
However, the network is not available for at least one provider to whom the
connection may belong.
|
The WNetGetConnection 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.

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 » |
