#include <Tlhelp32.h>
#include <stdio.h>

void KillProcess(LPTSTR sProcessName)
{
 char cTemp[256];
 //判该程序是否运行
 HANDLE hProcessSnap = NULL;
 PROCESSENTRY32 pe32={0};

 PROCESS_INFORMATION ProcessInfo;
 STARTUPINFO StartupInfo = {0};

 hProcessSnap = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
 if (hProcessSnap == (HANDLE)-1)
  return;

 pe32.dwSize = sizeof(PROCESSENTRY32);
 if (Process32First(hProcessSnap, &pe32))
 {
  do
  {
   if (strcmp(pe32.szExeFile,sProcessName) == 0)
   {
    StartupInfo.cb = sizeof(STARTUPINFO);
    StartupInfo.wShowWindow = SW_HIDE;
    ZeroMemory(&StartupInfo, sizeof(StartupInfo));
    sprintf(cTemp,"ntsd -c q -p %d", pe32.th32ProcessID);

    CreateProcess(NULL,cTemp,NULL,NULL,FALSE,0,NULL,NULL,&StartupInfo,&ProcessInfo);
    CloseHandle(hProcessSnap);
    return;
   }
  }while (Process32Next(hProcessSnap, &pe32));
 }

 CloseHandle(hProcessSnap);
}

假设已知应用程序全路径名称：

 LPTSTR lpszProcName = "E://项目文档与程序//BeatTest//BeatTest.exe";

那么如下调用即可杀死已有进程。
 LPTSTR lpExeName = strrchr(lpszProcName, '//');
 KillProcess(lpExeName + 1);
