How to execute another exe from a C++ program in Windows
提问by ThePrince
I want my C++ program to execute another .exe, in Windows. How would I do this? I am using Visual C++ 2010.
我希望我的 C++ 程序在 Windows 中执行另一个 .exe。我该怎么做？我正在使用 Visual C++ 2010。
Here is my code
这是我的代码
#include "stdafx.h"
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
unsigned int input;
cout << "Enter 1 to execute program." << endl;
cin >> input;
if(input == 1) /*execute program here*/;
return 0;
}

This is a solution I found when looking for an answer previously.
It stated that you should always avoid using system() because:
这是我之前在寻找答案时找到的解决方案。
它指出您应该始终避免使用 system() ，因为：
- It is resource heavy
- It defeats security -- you don't know you it's a valid command or does the same thing on every system, you could even start up programs you didn't intend to start up. The danger is that when you directly execute a program, it gets the same privileges as your program -- meaning that if, for example, you are running as system administrator then the malicious program you just inadvertently executed is also running as system administrator.
- Anti virus programs hate it, your program could get flagged as a virus.
- 资源繁重
- 它破坏了安全性——你不知道这是一个有效的命令，或者在每个系统上做同样的事情，你甚至可以启动你不打算启动的程序。危险在于，当您直接执行程序时，它会获得与您的程序相同的权限——这意味着，例如，如果您以系统管理员身份运行，那么您无意中执行的恶意程序也会以系统管理员身份运行。
- 防病毒程序讨厌它，您的程序可能会被标记为病毒。
Instead CreateProcess() can be used.
Createprocess() is used to just start up an .exe and creating a new process for it. The application will run independent from the calling application.
相反，可以使用 CreateProcess()。
Createprocess() 用于启动一个 .exe 并为其创建一个新进程。应用程序将独立于调用应用程序运行。
#include <Windows.h>
void startup(LPCSTR lpApplicationName)
{
// additional information
STARTUPINFOA si;
PROCESS_INFORMATION pi;
// set the size of the structures
ZeroMemory(&si, sizeof(si));
si.cb = sizeof(si);
ZeroMemory(&pi, sizeof(pi));
// start the program up
CreateProcessA
(
lpApplicationName, // the path
argv[1], // Command line
NULL, // Process handle not inheritable
NULL, // Thread handle not inheritable
FALSE, // Set handle inheritance to FALSE
CREATE_NEW_CONSOLE, // Opens file in a separate console
NULL, // Use parent's environment block
NULL, // Use parent's starting directory
&si, // Pointer to STARTUPINFO structure
&pi // Pointer to PROCESS_INFORMATION structure
);
// Close process and thread handles.
CloseHandle(pi.hProcess);
CloseHandle(pi.hThread);
}

you can use the systemfunction
你可以使用这个system功能
int result = system("C:\Program Files\Program.exe");

Use the CreateProcess() Function.
使用 CreateProcess() 函数。

You can make a call using system
您可以使用 system
system("./some_command")

I believe this answer should work with different programs, I tested it with Chrome.
我相信这个答案应该适用于不同的程序，我用 Chrome 对其进行了测试。
// open program.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "string"
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
string command = "start chrome https://www.google.com/";
system(command.c_str());
return 0;
}
