如何根据进程名得到其PID?

Question

如题。

Answer 1

BOOL CALLBACK EnumWinProc(HWND hwnd, LPARAM lParam)
{
    DWORD dwID;    GetWindowThreadProcessId(hwnd, &dwID);
    if (dwID == (DWORD)lParam) {
        PostMessage(hwnd, WM_QUIT, 0, 0);
        return FALSE;
    }
    return TRUE;
}

Answer 2

HANDLE hSnapShot=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0 );
PROCESSENTRY32 procentry=sizeof(PROCESSENTRY32);
BOOL bFlag=Process32First( hSnapShot, &procentry ) ;
while( bFlag )
{
      if(stricmp(procentry.szExeFile,"你的程序名")==0)
          processid=procentry.th32ProcessID;    //找到
      bFlag=Process32Next(hSnapShot,&procentry);
}注意一个程序可能有几个实例同时运行，所以可能同时找到几个ID。

Answer 3

BOOL ShowProcess()//显示进程
{
    int i=0;
TCHAR* szFilePatch  = malloc(MAX_PATH ); //存放进程路径
HANDLE handle=CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
    PROCESSENTRY32* information = malloc(sizeof(PROCESSENTRY32));
if(Process32First(handle,information))
{
ListView_DeleteAllItems(hListView); //清空列表
//显示系统第一个进程的id号,线程数,优先级
_ltoa(information->th32ProcessID,Buffer,10);
AddItem(hListView, i,0, Buffer); 
AddItem(hListView,i,1,information->szExeFile);
_ltoa(information->cntThreads, Buffer, 10);
AddItem(hListView,i,2,Buffer);
_ltoa(information->pcPriClassBase,Buffer,10);
AddItem(hListView, i, 3, Buffer);
i++;
//显示其他进程信息
while(Process32Next(handle,information)!=FALSE)
{
_ltoa(information->th32ProcessID,Buffer,10); 
  AddItem(hListView, i,0,Buffer );//添加进程(ID号)
AddItem(hListView,i,1,information->szExeFile);//添加该进程映像名
_ltoa(information->cntThreads, Buffer, 10);
    AddItem(hListView,i,2,Buffer);//添加该进程的线程数
_ltoa(information->pcPriClassBase,Buffer,10);
AddItem(hListView, i, 3, Buffer); //添加进程优先级
if(strcmp(information->szExeFile, "System"))//进程"System"没有路径
{
     GetProPatch(information->th32ProcessID,szFilePatch);
     AddItem(hListView, i, 4, szFilePatch); //添加进程路径
}
i++;
}
}
free(szFilePatch);
free(information);
CloseHandle(handle);
    return TRUE;
}//添加项目,iItem为纵向列数,iSubItem为横向列数,lpstr为显示内容
BOOL  AddItem(HWND hWndListView, int iItem, int iSubItem, LPSTR lpstr)
{
if( 0 == iSubItem)
{
LV_ITEM lvi;
    lvi.mask = LVIF_TEXT | LVIF_IMAGE | LVIF_PARAM | LVIF_STATE;
    lvi.stateMask = 0;
    lvi.state = 0;
        lvi.iItem =  iItem;
lvi.iSubItem = iSubItem;
lvi.pszText = lpstr; // sends an LVN_GETDISPINFO
if( ListView_InsertItem(hWndListView,(LPARAM)&lvi) == -1)
        return FALSE;
}
else if( 0 < iSubItem)
               ListView_SetItemText(hWndListView, iItem, iSubItem ,lpstr);
    return TRUE;

}
