FensterText per ProcessID bekommen?

[bitsetter]

Hi,

mit EnumThreadWindows müsste es IMHO auch gehen, die Fenster in der Liste müsstest du eventuell nochmal filtern.
Mal schnell zusammengetippt:

Delphi-Quellcode:

uses TLHelp32, Contnrs;

type
  TWndItem = class(TObject)
    Wnd: HWND;
end;

function EnumThreadWndProc(Wnd: HWND; WndList: TObjectList): BOOL; stdcall;
var
  WndItem: TWndItem;
begin
  WndItem:= TWndItem.Create;
  WndItem.Wnd:= Wnd;
  WndList.Add(WndItem);
  Result:= true;
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  WndList: TObjectList;
  Thread32: TThreadEntry32;
  hThreadSnap: THandle;
  ProcId: DWord;
  i: integer;
  myBuf: array[0..250] of Char;
begin
  WndList:= TObjectList.Create;
  try
    ProcId := ...;//GetCurrentProcessId();
    hThreadSnap := CreateToolHelp32Snapshot(TH32CS_SNAPTHREAD, ProcId);
    if (hThreadSnap > 0) and (hThreadSnap <> INVALID_HANDLE_VALUE) then
      try
        ZeroMemory(@Thread32, SizeOf(TThreadEntry32));
        Thread32.dwSize := SizeOf(TThreadEntry32);
        if Thread32First(hThreadSnap, Thread32) then
          repeat
            if ProcId = Thread32.th32OwnerProcessID then
              EnumThreadWindows(Thread32.th32ThreadID, @EnumThreadWndProc, DWord(WndList));
          until not Thread32Next(hThreadSnap, Thread32);
      finally
        CloseHandle(hThreadSnap);
      end;

    for i:= 0 to Pred(WndList.Count) do
    begin
      if Windows.IsWindowVisible(TWndItem(WndList.Items[i]).Wnd) then
      begin
        GetWindowText(TWndItem(WndList.Items[i]).Wnd, myBuf, sizeof(myBuf));
        ListBox1.Items.Add(myBuf);
      end;
    end;

  finally
    WndList.Free;
  end;
end;
