初始化 GetKeyword 方法。 支持的平台:仅窗口 签名工 务 局: object.InitializeUserInput Bits [, Keyword]
返回值(RetVal)无返回值。 言论在调用 to 之前,必须使用此方法定义关键字。某些用户输入法除了通常返回的值之外,还可以接受关键字值,前提是已调用此方法来定义关键字。可以接受关键字的用户输入方法是:,,,,,,,和。GetKeywordGetKeywordGetIntegerGetRealGetDistanceGetAngleGetOrientationGetPointGetCorner 例子工 务 局: Sub Example_InitializeUserInput()
