Ungültiges Fenster Handle - seit 10.2. Tokyo

[alf.krause]

Der Debugger bleibt erst hier stehen

Code:

procedure TWinControl.MainWndProc(var Message: TMessage);
begin
  try
    try
      WindowProc(Message);
    finally
      FreeDeviceContexts;
      FreeMemoryContexts;
    end;
  except
    [B]Application.HandleException(Self)[/B];
  end;
end;

dann hier

Code:

procedure RaiseLastOSError(LastError: Integer; const AdditionalInfo: string); overload;
var
  Error: EOSError;
begin
  if LastError <> 0 then
    Error := EOSError.CreateResFmt(@SOSError, [LastError, SysErrorMessage(LastError), AdditionalInfo])
  else
    Error := EOSError.CreateRes(@SUnkOSError);
  Error.ErrorCode := LastError;
  raise Error;
end;
