vb中怎样使用windows信使服务(net send) 在局域网中可以随时侦测接线的机器

[jinesc]

shell + ping

把你想要执行的命令全部都写到Bat批处理文件中，

再用 shell 去执行这个Bat文件就可以了，

1、加API：
Public Declare Function NetMessageBufferSend Lib _
"NETAPI32.DLL" _
(Server As Any, _
yToName As Byte, _
yFromName As Any, _
yMsg As Byte, _
ByVal lSize As Long) As Long

'创建信使服务

Public Function SendMsg(sToUser As String, sFromUser As String, sMessage As String) As Boolean


2、调用以下方法

'-------------------------------------------
'
' 函数名 发消息（信使）
'
'传入参数
'sToUser: 被发送对象机器名或IP
'sFromUser: 发送者机器名或IP
'sMessage: 消息内容
'
'返回值
'SendMsg: 布尔值 T:成功、F:失败

'2004/02/05
'--------------------------------------------
Dim yToName() As Byte
Dim yFromName() As Byte
Dim yMsg() As Byte
Dim l As Long

yToName = sToUser & vbNullChar
yFromName = sFromUser & vbNullChar
yMsg = sMessage & vbNullChar

If NetMessageBufferSend(ByVal 0&, yToName(0), _
ByVal 0&, yMsg(0), _
UBound(yMsg)) = NERR_Success Then
SendMsg = True
End If
End Function


3、加分！！！！！！！！

试试

Private Declare Function NetMessageBufferSend Lib "NETAPI32.DLL" _
(Server As Any, _
yToName As Byte, _
yFromName As Any, _
yMsg As Byte, _
ByVal lSize As Long) _
As Long

Private Sub Command1_Click()
Dim X As Boolean
X = SendMsg(TxtTo.Text, TxtFrom.Text, TxtMsg.Text)
If X Then
MsgBox "消息已被成功发送", vbInformation, "发送消息"
Else
MsgBox "发送消息失败", vbCritical, "发送消息"
End If
End Sub

Private Function SendMsg(sToUser As String, _
sFromUser As String, _
sMessage As String) _
As Boolean

Dim yToName() As Byte
Dim yFromName() As Byte
Dim yMsg() As Byte
Dim l As Long

yToName = sToUser & vbNullChar
yFromName = sFromUser & vbNullChar
yMsg = sMessage & vbNullChar

If NetMessageBufferSend(ByVal 0&, yToName(0), _
ByVal 0&, yMsg(0), UBound(yMsg)) = NERR_Success Then
SendMsg = True
End If
End Function

Private Sub Command2_Click()
End
End Sub
