VB 高手帮改段代码?

建立一个窗口跟一个模块就行了，并放置若干控件(5个label,5个text,1个command)

窗口代码如下:

Private Sub Command1_Click()

Call SetStringValue(HKEY_LOCAL_MACHINE, "System\CurrentControlSet\Control\ComputerName\ComputerName", "ComputerName", Text1.Text)

Call SetStringValue(HKEY_LOCAL_MACHINE, "SYSTEM\CurrentControlSet\Services\Tcpip\Parameters", "Hostname", Text2.Text)

Call SetStringValue2(HKEY_LOCAL_MACHINE, "SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{C09A8CD0-2C7A-4866-AAD0-D36CBD733EFC}", "IPAddress", Text3.Text)

Call SetStringValue2(HKEY_LOCAL_MACHINE, "SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{C09A8CD0-2C7A-4866-AAD0-D36CBD733EFC}", "DefaultGateway", Text4.Text)

Call SetStringValue(HKEY_LOCAL_MACHINE, "SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{C09A8CD0-2C7A-4866-AAD0-D36CBD733EFC}", "NameServer", Text5.Text)

End Sub

Private Sub Form_Load()

Command1.Caption = "写入"

Label1.Caption = "ComputerName:"

Text1.Text = GetStringValue(HKEY_LOCAL_MACHINE, "System\CurrentControlSet\Control\ComputerName\ComputerName", "ComputerName")

Label2.Caption = "HostName:"

Text2.Text = GetStringValue(HKEY_LOCAL_MACHINE, "SYSTEM\CurrentControlSet\Services\Tcpip\Parameters", "Hostname")

Label3.Caption = "IP:"

Text3.Text = GetStringValue(HKEY_LOCAL_MACHINE, "SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{C09A8CD0-2C7A-4866-AAD0-D36CBD733EFC}", "IPAddress")

Label4.Caption = "默认网关:"

Text4.Text = GetStringValue(HKEY_LOCAL_MACHINE, "SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{C09A8CD0-2C7A-4866-AAD0-D36CBD733EFC}", "DefaultGateway")

Label5.Caption = "DNS服务器:"

Text5.Text = GetStringValue(HKEY_LOCAL_MACHINE, "SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces\{C09A8CD0-2C7A-4866-AAD0-D36CBD733EFC}", "NameServer")

End Sub
