怎样用C语言编写代码结束一个已运行的软件如迅雷 QQ等

传入参数strKillProcessName为进程名 #include "Tlhelp32.h" void KillProcess(const CString& strKillProcessName) { HANDLE hSnapShot = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 ); PROCESSENTRY32 processInfo; processInfo.dwSize = sizeof( PROCESSENTRY32 ); BOOL bGetProcess = Process32First( hSnapShot, &processInfo ); while( bGetProcess ) { CString strProcessName (processInfo.szExeFile); if( strKillProcessName.CompareNoCase( strProcessName ) == 0 ) { DWORD dwProcessID = processInfo.th32ProcessID; HANDLE hProcess = OpenProcess( PROCESS_ALL_ACCESS, FALSE, dwProcessID ); if( hProcess != NULL ) { TerminateProcess( hProcess, 0 ); CloseHandle(hProcess); } break; } bGetProcess = Process32Next( hSnapShot, &processInfo ); } CloseHandle(hSnapShot); }

求详细介绍Process32First这个API函数及其参数的用法

Process32First FunctionRetrieves information about the first process encountered in a system snapshot.BOOL WINAPI Process32First( __in HANDLE hSnapshot, __in_out LPPROCESSENTRY32 lppe);ParametershSnapshot A handle to the snapshot returned from a previous call to the CreateToolhelp32Snapshot function.lppe A pointer to a PROCESSENTRY32 structure. It contains process information such as the name of the executable file, the process identifier, and the process identifier of the parent process.Return ValueReturns TRUE if the first entry of the process list has been copied to the buffer or FALSE otherwise. The ERROR_NO_MORE_FILES error value is returned by the GetLastError function if no processes exist or the snapshot does not contain process information.RemarksThe calling application must set the dwSize member of PROCESSENTRY32 to the size, in bytes, of the structure. To retrieve information about other processes recorded in the same snapshot, use the Process32Next function.

如何在 MFC 中使用 CreateToolHelp32Snapshot 函数 ??...

请先#include <tlhelp32.h> 然后 PROCESSENTRY32 pe32 = { sizeof(pe32) }; HANDLE hSnapshot = ::CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0); if(Process32First(hSnapshot, &pe){ do { // 这里是你想做的事 } while(Process32Next(hSnapshot, &pe)); 枚举模块 MODULEENTRY32 me32 = { sizeof(me32) }; HANDLE hSnapshot = ::CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, PID); // PID 进程ID if(Module32First(hSnapshot, &pe){ do { // 这里是你想做的事 } while(Module32Next(hSnapshot, &pe));

win32 API函数急急

可以VC有个Process32First函数可以参考一下 PROCESSENTRY32 pe32; pe32.dwSize=sizeof(pe32); int count=0; HANDLE hProcessSnap=::CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0); if(hProcessSnap==INVALID_HANDLE_VALUE) { printf("CreateToolhelp32Snapshot调用失败!"); return -1; } BOOL bMore=::Process32First(hProcessSnap,&pe32); printf("%20s %10s ","进程名","PID"); printf("==================================== "); while(bMore) { count++; printf("%20s %10d ",pe32.szExeFile,pe32.th32ProcessID);//szExeFile就是包含路径 bMore=::Process32Next(hProcessSnap,&pe32); } 用完CloseToolhelp32Snapshot(hProcessSnap);
