次のコード例は、列挙FrameStyle型の使用方法を示しています。The following code example demonstrates using the FrameStyle enumeration. この例を実行するには、いくつかのコントロールを含む Form1 という名前のフォームに次のコードを貼り付けます。この例では、MouseDown、MouseMove、および MouseUp イベントが、この例で定義されているイベントハンドラーメソッドに接続されていることを前提としています。To run the example, paste the following code in a form called Form1 containing several controls.This example assumes the MouseDown, MouseMove, and MouseUp events are connected to the event-handler methods defined in the example.
