Windowsアプリの起動時間、どれくらいかかってますか？

●VC.exe(Visual C++プロジェクト Win32 コンソール プロジェクト)

#include "stdafx.h"

#include <windows.h>



int _tmain(int argc, _TCHAR* argv[])

{

    //現在時刻をファイルに記述

    FILE *fp;

    fp = fopen("C:\\Temp\\StartupTime.log", "w");

    if(fp == NULL) {

        printf("file open failed.");

        return 1;

    }

    SYSTEMTIME st;

    GetLocalTime(&st);

    fprintf(fp,"%d/%02d/%02d %02d:%02d:%02d.%03d\n",

        st.wYear, st.wMonth, st.wDay,

        st.wHour,st.wMinute,st.wSecond,st.wMilliseconds);

    fclose(fp);

    

    //C#で作ったexeを実行

    ShellExecute(NULL, NULL, "CS.exe", NULL, ".", SW_SHOWNORMAL);



    return 0;

}
