c++我还在努力学习ING 所以 用VB 代替了~~~

上面是模块的申明，参见MSDN
那么 这有什么用呢？
首先 我们 可以用iphlpapi.dl 获得当前计算机上安装的网络适配器：
Combo1.Clear
Combo1.AddItem "所有网络适配器"
Dim Net As MIB_IFTABLE
LenIfT = Len(Net)
RValue = GetIfTable(Net, LenIfT, True)
'由Net.dwNumEntries获得接口数量，然后用for…next循环获取每个接口信息:
For i = 0 To Net.dwNumEntries - 1
With Net.MIB_Table(i)
Combo1.AddItem StrConv(.bDescr, vbUnicode)
End With
Next
Combo1.ListIndex = 0
然后我们 就可以做一个简单的网络折线统计图啦~~
建一个定时器 代码如下：
Private Sub Nettext_Timer()
On Error Resume Next
Dim Net As MIB_IFTABLE
LenIfT = Len(Net)
RValue = GetIfTable(Net, LenIfT, True)
For i = 1 To Net.dwNumEntries
UpCache(i) = Up(i)
DownCache(i) = Down(i)
Down(i) = Net.MIB_Table(i - 1).dwInOctets
Up(i) = Net.MIB_Table(i - 1).dwOutOctets
If (UpCache(i) > 0) And (DownCache(i) > 0) Then
UpSpeed(i) = (Up(i) - UpCache(i)) / (Nettext.Interval / 1000)
DownSpeed(i) = (Down(i) - DownCache(i)) / (Nettext.Interval / 1000)
End If
If (UpSpeed(i) / 2) > UpSpeedMax(i) Then
UpSpeedMax(i) = UpSpeed(i) / 2
End If
If (DownSpeed(i) / 2) > DownSpeedMax(i) Then
DownSpeedMax(i) = DownSpeed(i) / 2
End If
For j = 1 To 20
Updata(i, j) = Updata(i, j + 1)
Downdata(i, j) = Downdata(i, j + 1)
Next j
Updata(i, 21) = UpSpeed(i) / 2
Downdata(i, 21) = DownSpeed(i) / 2
If (DownSpeedMax(i) > MaxSpeed(i)) Or (UpSpeedMax(i) > MaxSpeed(i)) Then
If DownSpeedMax(i) > UpSpeedMax(i) Then
MaxSpeedCache(i) = MaxSpeed(i)
MaxSpeed(i) = DownSpeedMax(i)
Else
MaxSpeedCache(i) = MaxSpeed(i)
MaxSpeed(i) = UpSpeedMax(i)
End If
End If
Next i
'--------------所有网络适配器---------------
Up(0) = 0
Down(0) = 0
DownSpeed(0) = 0
UpSpeed(0) = 0
For i = 1 To Net.dwNumEntries
Up(0) = Up(0) + Up(i)
Down(0) = Down(0) + Down(i)
DownSpeed(0) = DownSpeed(0) + DownSpeed(i)
UpSpeed(0) = UpSpeed(0) + UpSpeed(i)
Next i
For j = 1 To 20
Updata(0, j) = Updata(0, j + 1)
Downdata(0, j) = Downdata(0, j + 1)
Next j
Updata(0, 21) = UpSpeed(0) / 2

If (UpSpeed(0) / 2) > UpSpeedMax(0) Then

End If

End If

Else

。。。。。我忽然发现 我不知道 该说些什么。。。。
绝对是自己 写的啊~~
为证明自己 附上我为高中同学（现在我毕业啦~~）写的 Fan{过}{滤}Qiang程序（越过学校对教室电脑的网络封锁）
望转正啊~~~
