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.
Declare Function WNetAddConnection Lib "mpr.dll" Alias "WNetAddConnectionA" (ByVal lpszNetPath As String, ByVal lpszPassword As String, ByVal lpszLocalName As String) As Long
Operating Systems Supported
Requires Windows NT 3.1 or later; Requires Windows 95 or later
Points to a null-terminated string that specifies the network resource to connect to.
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.
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.
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:
Access is denied.
The device specified in the lpLocalName parameter is already connected.
The device type and the resource type do not match.
The value specified in lpLocalName is invalid.
The value specified in the lpRemoteName parameter is not valid or cannot be located.
The user profile is in an incorrect format.
The system is unable to open the user profile to process persistent connections.
An entry for the device specified in lpLocalName is already in the user profile.
A network-specific error occurred. To get a description of the error, use the WNetGetLastError function.
The specified password is invalid.
The operation cannot be performed because either a network component is not started or the specified name cannot be used.
The network is not present.
The function returns error codes and sets the error code values returned by GetLastError.
