예제

다음 코드 예제에서는 TextBox, 클래스를 파생 합니다.The following code example uses TextBox, a derived class. 쉽게 Click 에 대 한 이벤트 처리기 MenuItem 잘라내기, 복사, 붙여넣기 및 실행 취소 작업을 수행 하는 개체입니다.It provides Click event handlers for MenuItem objects that perform Cut, Copy, Paste, and Undo operations. 이 예제에서는 한 TextBox 라는 컨트롤 textBox1 만들었습니다.This example requires that a TextBox control named textBox1 has been created.

설명

컨트롤에서 텍스트를 선택한 경우이 메서드는 텍스트 상자에서 텍스트 잘라내기만.This method will only cut text from the text box if text is selected in the control. 사용 하는 대신이 메서드를 사용할 수 있습니다는 Clipboard 텍스트 상자에 텍스트를 복사 및 이동 되도록 클래스를 클립보드합니다.You can use this method, instead of using the Clipboard class, to copy text in the text box and move it to the Clipboard.
