How to call a powershell script from a C code

你说的曾经没有我的故事 提交于 2019-12-04 19:33:32

C++ code :

#include<iostream>
#include <io.h>   // For access().
#include <sys/types.h>  // For stat().
#include <sys/stat.h>   // For stat().
#include <string>
using namespace std;


void main()
{
       string strPath = "d:\\callPowerShell.ps1";
//access function:
       //The function returns 0 if the file has the given mode.
       //The function returns –1 if the named file does not exist or does not have the given mode
       if(access(strPath.c_str(),0) == 0)
       {

              system("start powershell.exe Set-ExecutionPolicy RemoteSigned \n");
              system("start powershell.exe d:\\callPowerShell.ps1");
              system("cls");
       }
       else
       {
              system("cls");
              cout << "File is not exist";
              system("pause");
       }
}

First error :

#include <io.h>   // For access().

access is in this lib:

#include <cstdlib>

Next :

error: 'system' was not declared in this scope

#include <unistd.h>

And finally :

The caractere '\' is a special caractere for C/C++ then you have to add another '\' like :

system("start powershell.exe C:\\users\\sqtk-mal\\script1.ps1");

In C++

#include <cstdlib>

std::system("command");

In c

#include <stdlib.h>

system("command");
 #include<iostream>
 #include <io.h>   // For access().
 #include <sys/types.h>  // For stat().
 #include <sys/stat.h>   // For stat().
 #include <string>
 using namespace std;


 int main()
 {
   string strPath = "C:\users\sqtk-mal\script1.ps1";
   //access function:
   //The function returns 0 if the file has the given mode.
   //The function returns –1 if the named file does not exist or does not have the given mode
   if(access(strPath.c_str(),0) == 0)
   {

          system("start powershell.exe Set-ExecutionPolicy RemoteSigned \n");
          system("start powershell.exe C:\users\sqtk-mal\script1.ps1");
          system("cls");
   }
   else
   {
          system("cls");
          cout << "File is not exist";
          system("pause");
   }
}

On using this code, codeblocks gives an error
