WMI を使用してコマンド ライン引数を渡して、ジョブ ID を調べようとしています。int main(int argc, char **argv) { HRESULT hres;

        CloseHandle(hProcess);

pLoc->Release();
pSvc->Release();
CoUninitialize();
getchar();
return 0; // Program successfully completed.

}

上記は C++ コードです。私の質問は、nsis の構造体にアクセスする方法です。上記のコードの下の行のように

1. hres = pLoc->ConnectServer(
2. hres = pEnumerator->Next(WBEM_INFINITE, 1, &pclsObj, &uReturn);
3. hres = pclsObj->Get

これについて私を助けてください...

WmiInspectorプラグインを見ましたか? または、既存の C++ コードを使用してカスタム プラグインを作成します。

NSIS で Windows API または COM インターフェイスを呼び出すには、システム プラグインを使用する必要があります。

!include LogicLib.nsh
!define CLSCTX_INPROC_SERVER 0x1
!define CLSID_ApplicationAssociationRegistrationUI {1968106d-f3b5-44cf-890e-116fcb9ecef1}
!define IID_IApplicationAssociationRegistrationUI {1f76a169-f994-40ac-8fc8-0959e8874710} ;[Vista+]

section
;NSIS has called CoInitialize
System::Call 'OLE32::CoCreateInstance(g "${CLSID_ApplicationAssociationRegistrationUI}",i 0,i ${CLSCTX_INPROC_SERVER},g "${IID_IApplicationAssociationRegistrationUI}",*i.r1)i.r0' ;ptr is now in $1 and hr in $0

    System::Call '$1->3(w "Internet Explorer")i.r0' ;IApplicationAssociationRegistrationUI::LaunchAdvancedAssociationUI

IID とメソッドの vtable オフセットを手動で検索する必要があるため、多くの COM を使用するのは楽しくありません...
