我需要每10秒检查1.exe，2.exe是否正在运行，如果没有运行则运行它。 [英] I need 1.exe, 2.exe to be checked every 10 seconds whether it is running or not and if not running then run it.

问题描述

_WIN32_WINNT 0x0500 // define needed to use GetConsoleWindow() function
#include <windows.h>
#include <tlhelp32.h>
#include <string.h>
 
int main()
{    
    BOOL is_running = 0;
    DWORD pid = 0;
    PROCESSENTRY32 pe32;
    pe32.dwSize = sizeof(PROCESSENTRY32);
 
    //start of the checking loop, check happens once in every 10 seconds
    while(1){ 
        //take a snapshot of windows running processes
        HANDLE hProcessSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
        Process32First(hProcessSnapshot, &pe32);
 
        //compare the name of each process in the process list with "sleep.exe"
        while (Process32Next(hProcessSnapshot, &pe32)) {
            if (!strcmp("1.exe", pe32.szExeFile)) {
                is_running = 1; //change is_running status if name matches
                break;
            }
        }
 
        if(!is_running) system("start 1.exe"); //start the process if it's not running
        is_running = 0; //restore is_running status
        Sleep(10000); //sleep for 10 seconds
       
        while (Process32Next(hProcessSnapshot, &pe32)) {
            if (!strcmp("2.exe", pe32.szExeFile)) {
                is_running = 1; //change is_running status if name matches
                break;
            }
        }
 
        if(!is_running) system("start 2.exe"); //start the process if it's not running
        is_running = 0; //restore is_running status
        Sleep(10000); //sleep for 10 seconds        
    }
 
    return 0;
}

推荐答案

while(1){
        HANDLE hProcessSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);
// ...
        HANDLE hProcessSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);

您正在尝试重新定义相同的变量。从第二次出现中删除类型（ HANDLE ）。或者如果你想要两个这样的句柄，那么重命名其中一个。

You are trying to redefine the same variable. Remove the type (HANDLE) from the second occurrence. Or if you want two such handles then rename one of them.
