获取进程pid、根据进程pid获取线程pid、获取线程进程句柄

=======================================

获取进程pid

=======================================

#include "tlhelp32.h"

//获取PID
UINT GetProPid(LPCTSTR pszExeFile)
{
//查找当前的进程的pid
UINT nProcessID = 0;
PROCESSENTRY32 pe = {sizeof(PROCESSENTRY32)};
HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPALL, 0);
if (hSnapshot != INVALID_HANDLE_VALUE)
{
if (Process32First(hSnapshot, &pe))
{
while (Process32Next(hSnapshot, &pe))
{
if (lstrcmpi(pszExeFile, pe.szExeFile) == 0)
{
nProcessID = pe.th32ProcessID;
break;
}
}
}
CloseHandle(hSnapshot);
}
return nProcessID;
}

//调用

UINT dwProcessID=GetProPid(_T("explorer.exe"));

=======================================

根据进程pid获取线程pid

=======================================

DWORD dwThreadID;

THREADENTRY32 te32 = {sizeof(te32)};
HANDLE hThreadSnap = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD,0);
if( Thread32First( hThreadSnap, &te32) )
{
do{
if( dwProcessID == te32.th32OwnerProcessID )
{
dwThreadID = te32.th32ThreadID;
break;
}
}while( Thread32Next( hThreadSnap, &te32) );
}

=======================================

根据进程id获取进程名

=======================================

BOOL   GetProcess(int   nID)

{

CString strName;
HANDLE hProcessSnap=NULL;
PROCESSENTRY32 pe32={0};
hProcessSnap=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
if(hProcessSnap==(HANDLE)-1)
{
::MessageBox(NULL,L"查询进程失败！:(",L"错误提示",MB_OK);

return   FALSE;
}
pe32.dwSize=sizeof(PROCESSENTRY32);
if(Process32First(hProcessSnap,&pe32))
{
do
{
if(nID==pe32.th32ProcessID) //判断制定进程号
{
strName.Format(L"进程编号%d的进程名为：%s",nID,pe32.szExeFile);
AfxMessageBox(strName);
}
}
while(Process32Next(hProcessSnap,&pe32));
}
else
{
::MessageBox(NULL,L"出现意外错误！",L"错误提示",MB_OK);

return   FALSE;
}
CloseHandle(hProcessSnap);

return   TRUE;

}

=======================================

获取句柄

=======================================

HANDLE hProcess=NULL;
HANDLE hThread=NULL;

hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, dwProcessID);   //进程句柄
hThread = OpenThread(THREAD_ALL_ACCESS , FALSE, dwThreadID);        //线程句柄
