分享有人了解wnetaddconnection函数吗?
有没有高手帮帮我啊,我用这个函数想实现远程登陆一台机器,可以实现再连接而不用输入用户名和密码,可是却不成功.我的程序没有问题(应该是),因为我把lpremotename改为另外一台机器时却成功了.这会不会是远程机器的设置问题?
请高手帮帮我!

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, callGetLastError. 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 byGetLastError.
QuickInfo
Windows NT: Use version 3.1 or later.
Windows: Use Windows 95 or later.
Windows CE: Unsupported.
Header: Declared in winnetwk.h.
Import Library: Use mpr.lib.
