Remarks

이 속성을 true로 설정 하면 물음표를 포함 하는 작은 단추가 닫기 단추의 왼쪽에 있는 캡션 표시줄에 나타납니다.When this property is set to true, a small button with a question mark appears in the caption bar to the left of the Close button. 응용 프로그램에 대 한 도움말을 표시 하려면이 단추를 사용할 수 있습니다.You can use this button to display help for your application. 양식의 도움말 단추가 클릭 될 때 사용자에 게 도움말 정보를 표시 하는 HelpRequested 이벤트에 대 한 이벤트 처리기를 만들 수 있습니다.You can create an event handler for the HelpRequested event to display Help information to the user when the Help button of the form is clicked.

도움말 단추를 표시 하려면 폼의 ControlBox 속성 값이 true(기본값) 여야 합니다.To display a Help button, the value of the form's ControlBox property must be true, its default value. ControlBox 속성은 캡션 표시줄의 오른쪽 위 모퉁이에 최대화 단추, 최소화 단추, 도움말 단추 및 닫기 단추와 같은 컨트롤이 포함 되는지 여부를 결정 합니다.The ControlBox property determines whether the upper-right corner of the caption bar contains controls such as a maximize button, a minimize button, a help button, and a close button. 또한 폼의 FormBorderStyle 속성을 FormBorderStyle.FixedSingle, FormBorderStyle.Sizable, FormBorderStyle.Fixed3D또는 FormBorderStyle.FixedDialog으로 설정 해야 합니다.In addition, you must also set the form's FormBorderStyle property to FormBorderStyle.FixedSingle, FormBorderStyle.Sizable, FormBorderStyle.Fixed3D, or FormBorderStyle.FixedDialog.

Important

최대화 또는 최소화 단추가 표시 되는 경우 HelpButton 속성 값은 무시 됩니다.The value of the HelpButton property is ignored if the Maximize or Minimize buttons are shown.
