Form in den Vordergrund bringen

[n000b]

Zitat von lkz633:

hatte das gleiche Problem, habe dann diesen Code gefunden, ich glaube von swissdelphicenter:

Delphi-Quellcode:

function ForceForegroundWindow(hwnd: THandle): Boolean;
const
  SPI_GETFOREGROUNDLOCKTIMEOUT = $2000;
  SPI_SETFOREGROUNDLOCKTIMEOUT = $2001;
var 
  ForegroundThreadID: DWORD; 
  ThisThreadID: DWORD; 
  timeout: DWORD; 
begin 
  if IsIconic(hwnd) then ShowWindow(hwnd, SW_RESTORE); 

  if GetForegroundWindow = hwnd then Result := True 
  else 
  begin 
    // Windows 98/2000 doesn't want to foreground a window when some other 
    // window has keyboard focus 

    if ((Win32Platform = VER_PLATFORM_WIN32_NT) and (Win32MajorVersion > 4)) or 
      ((Win32Platform = VER_PLATFORM_WIN32_WINDOWS) and 
      ((Win32MajorVersion > 4) or ((Win32MajorVersion = 4) and 
      (Win32MinorVersion > 0)))) then 
    begin 
      // Code from Karl E. Peterson, [url]www.mvps.org/vb/sample.htm[/url] 
      // Converted to Delphi by Ray Lischner 
      // Published in The Delphi Magazine 55, page 16 

      Result := False; 
      ForegroundThreadID := GetWindowThreadProcessID(GetForegroundWindow, nil); 
      ThisThreadID := GetWindowThreadPRocessId(hwnd, nil); 
      if AttachThreadInput(ThisThreadID, ForegroundThreadID, True) then 
      begin 
        BringWindowToTop(hwnd); // IE 5.5 related hack 
        SetForegroundWindow(hwnd); 
        AttachThreadInput(ThisThreadID, ForegroundThreadID, False); 
        Result := (GetForegroundWindow = hwnd); 
      end; 
      if not Result then 
      begin 
        // Code by Daniel P. Stasinski 
        SystemParametersInfo(SPI_GETFOREGROUNDLOCKTIMEOUT, 0, @timeout, 0); 
        SystemParametersInfo(SPI_SETFOREGROUNDLOCKTIMEOUT, 0, TObject(0), 
          SPIF_SENDCHANGE); 
        BringWindowToTop(hwnd); // IE 5.5 related hack 
        SetForegroundWindow(hWnd); 
        SystemParametersInfo(SPI_SETFOREGROUNDLOCKTIMEOUT, 0, TObject(timeout), SPIF_SENDCHANGE); 
      end; 
    end 
    else 
    begin 
      BringWindowToTop(hwnd); // IE 5.5 related hack 
      SetForegroundWindow(hwnd); 
    end; 

    Result := (GetForegroundWindow = hwnd); 
  end; 
end;

Und wie ruft man das auf?

hwnd ist das Handle von dem Fenster, was man in den Vordergrund bringen möchte.
