I use the following code to determine the processes that are running, 
but how can I find out which application has the focus (in which 
application user is currently working)

  ListBox1->Items->Clear();
  HANDLE snapshot;
  PROCESSENTRY32 processinfo;
  processinfo.dwSize = sizeof(processinfo);
  snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS,0);
  if (snapshot == NULL)
   return;
  bool status = Process32First(snapshot, &processinfo);
  while(status)
   {
   ListBox1->Items->Add(processinfo.szExeFile);
   status = Process32Next(snapshot, &processinfo);
   }
  Form1->Caption = IntToStr(ListBox1->Items->Count);

thanks in advance
tom

The window with which the user is currently working can be found with the 
Windows API function GetForegroundWindow.  You might then use the returned 
HWND in a call to GetWindowProcessId.
