你不應該使用WShell COM對象運行cmd.exe
進行。這是矯枉過正。您可以改用CreateProcess()
。但是,在可編程運行cmd.exe
時,不能使用>
運算符重定向其輸出,該運算符只能在實際的命令窗口中運行。您可以改用STARTUPINFO
結構將輸出重定向到與CreatePipe()
創建一個匿名管道,然後你可以使用ReadFile()
該管道讀取。根本不需要使用臨時文件。 MSDN有關於這個主題的一篇文章:
Creating a Child Process with Redirected Input and Output
有大量的演示Delphi中這種技術的例子左右浮動。
話雖這麼說,更好的選擇是不使用netsh
在所有。 Windows 7和更高版本有一個Mobile Broadband API。您可以直接在您的代碼中枚舉MBN接口。
例如,使用WwanEnumerateInterfaces()
功能:
unit WwApi;
{$MINENUMSIZE 4}
interface
uses
Windows;
const
WWAN_STR_DESC_LENGTH = 256;
type
WWAN_INTERFACE_STATE = (
WwanInterfaceStateNotReady,
WwanInterfaceStateDeviceLocked,
WwanInterfaceStateUserAccountNotActivated,
WwanInterfaceStateRegistered,
WwanInterfaceStateRegistering,
WwanInterfaceStateDeregistered,
WwanInterfaceStateAttached,
WwanInterfaceStateAttaching,
WwanInterfaceStateDetaching,
WwanInterfaceStateActivated,
WwanInterfaceStateActivating,
WwanInterfaceStateDeactivating
);
WWAN_INTF_OPCODE = (
WwanIntfOpcodePin,
WwanIntfOpcodeRadioState,
WwanIntfOpcodePreferredProviders,
WwanIntfOpcodeCurrentConnection,
WwanIntfOpcodeProvisionedContexts,
WwanIntfOpcodeActivateUserAccount,
WwanIntfOpcodeVendorSpecific,
WwanIntfOpcodeInterfaceObject,
WwanIntfOpcodeConnectionObject,
WwanIntfOpcodeAcState,
WwanIntfOpcodeClearManualConnectState,
WwanIntfOpcodeGetStoredRadioState,
WwanIntfOpcodeGetRadioInfo,
WwanIntfOpcodeHomeProvider
);
// I don't know the definition of this type!
WWAN_STATUS = DWORD; //?
WWAN_INTERFACE_STATUS = record

PWWAN_INTERFACE_INFO_LIST = ^WWAN_INTERFACE_INFO_LIST;
WWAN_INTERFACE_INFO_LIST = record
dwNumberOfItems: DWORD;
pInterfaceInfo: array[0..0] of WWAN_INTERFACE_INFO;
end;
function WwanOpenHandle(dwClientVersion: DWORD; pReserved: Pointer; var pdwNegotiatedVersion: DWORD; var phClientHandle: THandle): DWORD; stdcall;

unit uMain;

COM接口,給您更詳細的信息:

uses
// I found the MbnApi.pas unit on the DelphiPraxis forum:

// Otherwise, you can import the mbnapi.tlb TypeLibrary yourself...
//
MbnApi, ActiveX, ComObj;

爲什麼你在使用WShell COM對象來調用嗎? 'cmd.exe'?改用'CreateProcess()'。錯誤信息意味着'netsh'本身不能識別'mbn show interface'命令。你在哪個系統上運行?你爲什麼使用'netsh'? Windows有一個[移動寬帶API](https://msdn.microsoft.com/en-us/library/windows/desktop/dd323271.aspx),用['WwanEnumerateInterfaces()'](https://msdn.microsoft .COM/EN-US /庫/窗/臺式機/ dn313190.aspx)或['IMbnInterfaceManager'(https://msdn.microsoft.com/en-us/library/windows/desktop/dd430416.aspx)來獲得MBN接口列表。 –
謝謝雷米。 你能指點我一個排序的例子嗎?我只能在MSDN上找到。我在Windows 10 Pro上,沒有看到這個或任何相關的類型庫。 –
MBN接口的TypeLibrary是'mbnapi.tlb'。我在DelphiPraxis論壇上找到了一個[Delphi unit for it](http://www.delphipraxis.net/189688-windows-mbn-api-fuer-delphi-xe-portieren.html)('MbnApi.pas')。不過,您不需要TypeLibrary來調用'Wwan ...()'函數。 –
