Kein doppelter Programstart aber Fenster in den Vordergrund

[Rumpi]

Hallo alle zusammen,

alles Gute fürs Neue Jahr.

Delphi-Quellcode:

// ab damit in deine Tools.pas oder so

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; { ForceForegroundWindow }


....


var
  hW : hWnd;

  ....

  hW := FindWindowEx( 0,0,'TApplication', 'Deine Name den du suchst' );
  if IsWindow(hW ) then
  begin
    //... 
    Result := ForceForegroundWindow( hW );
    exit;
  end;

  // Bau deinen Mutex bitte mit ein
....

Ich hoffe das Hift dir Weiter
