查找进程: 就是调用windowApi遍历所有启动进程, 实现如下
bool FindProcess(std::string strProcessName, DWORD& nPid)
{ TCHAR tszProcess[64] = { 0 };
lstrcpy(tszProcess, _T(strProcessName.c_str()));
//查找进程
STARTUPINFO st;
PROCESS_INFORMATION pi;
PROCESSENTRY32 ps;
HANDLE hSnapshot;
memset(&st, 0, sizeof(STARTUPINFO));
st.cb = sizeof(STARTUPINFO);
memset(&ps, 0, sizeof(PROCESSENTRY32));
ps.dwSize = sizeof(PROCESSENTRY32);
memset(&pi, 0, sizeof(PROCESS_INFORMATION));
// 遍历进程
hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if (hSnapshot == INVALID_HANDLE_VALUE)
return false;
if (!Process32First(hSnapshot, &ps))
return false;
do {
if (lstrcmp(ps.szExeFile, tszProcess) == 0)
{
//找到制定的程序
nPid = ps.th32ProcessID;
CloseHandle(hSnapshot);
printf("找到进程: %s\n", tszProcess);
return true;
//getchar();
//return dwPid;
}
} while (Process32Next(hSnapshot, &ps));
CloseHandle(hSnapshot);
return false;
}
杀死进程: 就是通过遍历所有的启动的进程, 然后查找进程ID, 调用winapi将其杀死, 代码实现如下
bool KillProcess(DWORD dwPid)
{
printf("Kill进程Pid = %d\n", dwPid); getchar();
//关闭进程
HANDLE killHandle = OpenProcess(PROCESS_TERMINATE | PROCESS_QUERY_INFORMATION | // Required by Alpha
PROCESS_CREATE_THREAD | // For CreateRemoteThread
PROCESS_VM_OPERATION | // For VirtualAllocEx/VirtualFreeEx
PROCESS_VM_WRITE, // For WriteProcessMemory);
FALSE, dwPid);
if (killHandle == NULL)
return false;
TerminateProcess(killHandle, 0);
return true;
}
启动进程: 就是给出进程名绝对路径, 然后调用winapi启动
bool StartPrcess(std::string strProcessName)
{
TCHAR tszProcess[64] = { 0 };
lstrcpy(tszProcess, _T(strProcessName.c_str()));
//启动程序
SHELLEXECUTEINFO shellInfo;
memset(&shellInfo, 0, sizeof(SHELLEXECUTEINFO));
shellInfo.cbSize = sizeof(SHELLEXECUTEINFO);
shellInfo.fMask = NULL;
shellInfo.hwnd = NULL;
shellInfo.lpVerb = NULL;
shellInfo.lpFile = tszProcess; // 执行的程序名(绝对路径)
shellInfo.lpParameters = NULL;
shellInfo.lpDirectory = NULL;
shellInfo.nShow = SW_MINIMIZE; //SW_SHOWNORMAL 全屏显示这个程序
shellInfo.hInstApp = NULL;
printf("程序自动重启中.... \n");
ShellExecuteEx(&shellInfo); return true;
}
程序重启流程: 1: 先查找需要重启的程序进程Id
2: 启动需要重启的程序
3: 杀死第一步的进程id
代码上面已实现
