傳回

備註

IsInputChar視窗訊息前置處理期間會呼叫方法,以判斷指定的輸入字元是否應預先處理或直接傳送ToolStrip至。The IsInputChar method is called during window message preprocessing to determine whether the given input character should be preprocessed or sent directly to the ToolStrip. IsInputChar如果ToolStrip方法傳回,則會將指定的字元true直接傳送至。If the IsInputChar method returns true, the specified character is sent directly to the ToolStrip. 不過,如果方法false傳回,則會前置處理字元,而且只有在前置處理階段未使用ToolStrip時,才會傳送至。However, if the method returns false, the character is preprocessed and only sent to the ToolStrip if it is not consumed by the preprocessing phase. 字元的前置處理包含檢查字元是否為另一個控制項的助憶鍵。The preprocessing of a character includes checking whether the character is a mnemonic of another control.
