C++通过进程名获取进程句柄

记录下一段，比较常用的代码。

#include <TlHelp32.h> //通过进程ID获取进程句柄 //PROCESS_ALL_ACCESS 获取所有权限 //PROCESS_QUERY_INFORMATION 获取进程的令牌、退出码和优先级等信息 HANDLE GetProcessHandle(int nID) { return OpenProcess(PROCESS_ALL_ACCESS, FALSE, nID); } //通过进程名（带后缀.exe）获取进程句柄 HANDLE GetProcessHandle(LPCWSTR lpName) { HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); if (INVALID_HANDLE_VALUE == hSnapshot) { return NULL; } PROCESSENTRY32 pe = { sizeof(pe) }; BOOL fOk; for (fOk = Process32First(hSnapshot, &pe); fOk; fOk = Process32Next(hSnapshot, &pe)) { if (!_tcsicmp(pe.szExeFile, lpName)) // 不区分大小写 { CloseHandle(hSnapshot); return GetProcessHandle(pe.th32ProcessID); } } return NULL; }
