他の.exeを実行するためのwin32 API

Question

regsvr32をプログラム的に実行するwin32 APIについて知りたかったです。

私はCOMポートデバイスと通信できるアプリケーションを1つ持っていますが、通信を実現するためにregsvr32.exeを使用してMSCOMM32.ocxを登録する必要があります。

今は自分のコードにこの規定を追加して、regsvrを手動で実行する必要はありません。

Answer 2

は、なぜあなたはCOMコンポーネントを登録するREGSVR.EXEを実行したいですか？

次のコードを使用して、COMコンポーネントから直接DllRegisterServer（）を呼び出すことができます。

void RegisterDll() 
{ 
    typedef HRESULT (WINAPI *pDllRegisterServer)(void); 
    pDllRegisterServer pfnDllRegisterServer; 
    HMODULE hModule = LoadLibrary("MSCOMM32.ocx"); 
    pfnDllRegisterServer = (pDllRegisterServer) GetProcAddress(hMoudle , "DllRegisterServer"); 
    pfnDllRegisterServer(); 
}
