{
    OpenFileDialog openFileDialog1 = new OpenFileDialog
    {
        Title = 'open',
        Filter = ".stil file|*.stil"
    };
    openFileDialogResult = DialogResult.No;
    Thread invokeThread = new Thread(new ThreadStart(() => InvokeMethod(openFileDialog1)));
    invokeThread.SetApartmentState(ApartmentState.STA);
    invokeThread.Start();
    invokeThread.Join();
    DialogResult dr = openFileDialogResult;
    if (dr != DialogResult.OK)
    { return null; }
    string filePath = openFileDialog1.FileName;
