输入某年某月,判断该月有多少天,并判断是否为闰年,谁会编这个程序
闰年判断、某年某月有多少天'这两个问题实际可以归结为一个问题，即求某年某月有多少天，调用下面仅 1 条语句的简单函数就可以实现： '窗体添加控件 Command1、Command2 就可以查看 GetDays 的用法 Private Function GetDays(nYear As Long, nMonth As Long) As Long GetDays = Day(DateSerial(nYear, nMonth 1, 0)) End Function '问题1，通过判断 2 月份是否有 29 天确定是否闰年 Private Sub Command1_Click() Dim...全部

Caption = "闰年": Command2。Caption = "天数" End Sub。收起
