How do I open an .exe from another C++ .exe?
提问by S.Y
What I want to do is open an .exe from another .exe. I really don't know how to do this, so I searched the internet. I tried some suggested methods from the internet, but it didn't work.
我想要做的是从另一个 .exe 打开一个 .exe。我真的不知道该怎么做，所以我在网上搜索。我尝试了一些从互联网上推荐的方法，但没有奏效。
Here's my code:
这是我的代码：
#include <iostream>
#include <windows.h>
using namespace std;
int main()
{
system ("OpenFile.exe");
system ("pause");
return 0;
}
When I run it in DEV C++, it compiles, but I get a error. Can someone please help me?
当我在 DEV C++ 中运行它时，它可以编译，但出现错误。有人可以帮帮我吗？

You should always avoid using system()because
你应该总是避免使用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. If that doesn't scare you silly, check your pulse.
- 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。如果这还没有吓到你，那就检查一下你的脉搏吧。
- 防病毒程序讨厌它，您的程序可能会被标记为病毒。
You should use CreateProcess().
您应该使用CreateProcess()。
You can use Createprocess() to just start up an .exe and creating a new process for it. The application will run independent from the calling application.
您可以使用 Createprocess() 来启动一个 .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。
Here's an example I used in one of my projects:
这是我在我的一个项目中使用的示例：
#include <windows.h>
VOID startup(LPCTSTR lpApplicationName)
{
// additional information
STARTUPINFO 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
CreateProcess( lpApplicationName, // the path
argv[1], // Command line
NULL, // Process handle not inheritable
NULL, // Thread handle not inheritable
FALSE, // Set handle inheritance to FALSE
0, // No creation flags
NULL, // Use parent's environment block
NULL, // Use parent's starting directory
&si, // Pointer to STARTUPINFO structure
&pi // Pointer to PROCESS_INFORMATION structure (removed extra parentheses)
);
// Close process and thread handles.
CloseHandle( pi.hProcess );
CloseHandle( pi.hThread );
}
EDIT: The error you are getting is because you need to specify the path of the .exe file not just the name. Openfile.exe probably doesn't exist.
编辑：您收到的错误是因为您需要指定 .exe 文件的路径而不仅仅是名称。Openfile.exe 可能不存在。

I've had great success with this:
我在这方面取得了巨大的成功：
#include <iostream>
#include <windows.h>
int main() {
ShellExecute(NULL, "open", "path\to\file.exe", NULL, NULL, SW_SHOWDEFAULT);
}

Try this:
尝试这个：
#include <windows.h>
int main ()
{
system ("start notepad.exe") // As an example. Change [notepad] to any executable file //
return 0 ;
}

Provide the full path of the file openfile.exeand remember not to put forward slash /in the path such as
c:/users/username/etc....instead of that use
c:\\Users\\username\etc(for windows)
提供文件的完整路径openfile.exe并记住不要/在路径中放置斜杠，例如
c:/users/username/etc....代替使用
c:\\Users\\username\etc（对于Windows）
May be this will help you.
可能这会帮助你。

You can use the ifstream fin()function:
您可以使用该ifstream fin()功能：
#include <fstream>
int main(){
ifstream fin("C:\path\to\your\program\program.exe");
return 0;
}

When executable path has whitespace in system, call
当可执行路径在系统中有空格时，调用
#include<iostream>
using namespace std;
int main()
{
system("explorer C:\Program Files\Google\Chrome\Application\chrome.exe ");
system("pause");
return 0;
}

You are getting this error because you are not giving full path. (C:\Users...\file.exe) If you want to remove this error then either give full path or copy that application (you want to open) to the folder where your project(.exe) is present/saved.
您收到此错误是因为您没有提供完整路径。(C:\Users...\file.exe) 如果要删除此错误，请提供完整路径或将该应用程序（要打开）复制到项目（.exe）所在/保存的文件夹中。
#include <windows.h>
using namespace std;
int main()
{
system ("start C:\Users\Folder\chrome.exe https://www.stackoverflow.com"); //for opening stackoverflow through google chrome , if chorme.exe is in that folder..
return 0;
}
