如何以编程方式设置我的IP地址？
我的应用程序正在检查它,使用DelphiTricks中的代码(虽然我不确定About.com的代码是否可能更好)
我希望能够以编程方式设置地址以进行测试.并且(我不知道这是否重要),我希望能够这样做,即使我没有连接到任何网络(在笔记本电脑上,在火车上).
解决方法
要更改网络适配器的IP地址,可以使用
Win32_NetworkAdapterConfiguration WMI类的
EnableStatic方法或
AddIPAddress WinApi方法.
试试这个使用WMI的示例.
{$APPTYPE CONSOLE}
{$R *.res}
uses
SysUtils,ActiveX,Variants,ComObj;
procedure SetStaticIpAddress(const NetworkCard,IPAddress,Mask :string);
const
WbemUser ='';
WbemPassword='';
WbemComputer='localhost';
wbemFlagForwardOnly = $00000020;
var
FSWbemLocator : OLEVariant;
FWMIService : OLEVariant;
FWbemObjectSet : OLEVariant;
FWbemObject : OLEVariant;
FOutParams : OLEVariant;
vIpAddress : OLEVariant;
vMask : OLEVariant;
oEnum : IEnumvariant;
iValue : LongWord;
begin
FSWbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
FWMIService := FSWbemLocator.ConnectServer(WbemComputer,'root\CIMV2',WbemUser,WbemPassword);
FWbemObjectSet:= FWMIService.ExecQuery(Format('SELECT * FROM Win32_NetworkAdapterConfiguration Where Description="%s"',[NetworkCard]),'WQL',wbemFlagForwardOnly);
oEnum := IUnknown(FWbemObjectSet._NewEnum) as IEnumVariant;
if oEnum.Next(1,FWbemObject,iValue) = 0 then
begin
vIpAddress := VarArrayCreate([0,0],varVariant);
vIpAddress[0]:= IPAddress;
vMask := VarArrayCreate([0,varVariant);
vMask[0]:= Mask;
FOutParams:=FWbemObject.EnableStatic(vIpAddress,vMask);
// 0 - Successful completion,no reboot required
// 1 - Successful completion,reboot required
Writeln(Format('ReturnValue %s',[FOutParams]));
end
else
Writeln('Network card not found');
end;
begin
try
CoInitialize(nil);
try
SetStaticIpAddress('Network card name','192.168.1.1','255.255.255.0');
finally
CoUninitialize;
end;
except
on E:EOleException do
Writeln(Format('EOleException %s %x',[E.Message,E.ErrorCode]));
on E:Exception do
Writeln(E.Classname,':',E.Message);
end;
Writeln('Press Enter to exit');
Readln;
end.
