    // To get around this, start up a specific browser instance instead using one of
    // the overloads for Process.Start. You can examine the registry to find the
    // current default browser and launch that, or hard-code a specific browser.
    urlTextBox.ForeColor = Color.Black;

注釈

AutoSizeModeプロパティを新しい値に設定すると、フォームが再度レイアウトされます。Setting the AutoSizeMode property to a new value causes the form to be laid out again.

AutoSize およびAutoSizeModeプロパティの値に関係なく、Visual Studio フォームデザイナーではフォームのサイズが自動的に変更されません。A form does not automatically resize in the Visual Studio forms designer, regardless of the values of the AutoSize and AutoSizeMode properties. フォームは、この2つのプロパティの値に従って、実行時に自動的にサイズが変更されます。The form correctly resizes itself at run time according to the values of these two properties. これに対して、 UserControlカスタムのは、デザイン時と実行時の両方で自動的にサイズが変更されます。By contrast, a custom UserControl automatically resizes itself both at design time and at run time.
