Private Sub Form_Load()

For n = 1949 To 2008

Combo1.AddItem n

Next

Combo1.ListIndex = 0

For n = 1 To 12

Combo2.AddItem n

vb.net中怎样使DateTimePicker显示该月的阴历

VB或vb.NET或其它语言的控件都无法显示阴历,因为国外不使用阴历,你只能在网上找找第三方控件

如何应用VB.NET MonthCalendar控件

;   Visual Studio NET提供的MonthCalendar控件允许你选择日期和一组日期 这个控件允许用户方便地选择日期 它类似于让你选择一个特定日期的DataTimePicker控件 不过MonthCalendar控件还可以帮助你选择一个时间

使用MonthCalendar 控件

下面的例子说明如何使用MonthCalendar控件

在常用控件(Common Controls)下的工具箱(Toolbox)中找到MonthCalendar控件并将它添加到窗口表单(Window Form)中 设置以下属性

·Name mcDateSelection

·TodayDate 空

·MaxSelectionCount

·Selection Range Start 空

·Selection Range End 空

在Form Load事件中添加以下代码

mcDateSelection TodayDate = Now

然后建立列表A中的事件 在这个例子中 我设置MaxSelectionCount属性为 这意味着你只能在MonthCalendar控件中选择一个 而不是一组日期 在MonthView控件中选择一个日期 屏幕即类似于图A

图A

列表A Private Sub mcDateSelection_DateSelected(ByVal sender As Object ByVal e As System Windows Forms DateRangeEventArgs) Handles mcDateSelection DateSelected        MessageBox Show( Calendar Today s Date: mcDateSelection TodayDate vbCrLf _                Calendar Selected Start Date: mcDateSelection SelectionStart() vbCrLf _                Calendar Selected End Date: mcDateSelection SelectionEnd())    End Sub     既然你只能选择一个月中的某个特定的日期 而不是一组日期 那么 Selected Start Date和Selected End Date的值相同

现在 将MaxSelectionCount属性设为 然后重新运行代码 这次 你就可以选择一组日期(在这个例子中最多为 天) 而且 一旦你选择一组日期后 你将看到如图B所示的结果

图B

控件的其它用法

你可以利用MonthCalendar控件的许多其它属性和方法 使其满足你的需要 MSDN提供使用MonthCalendar控件的更多细节

vb.net vs2005里面的如何把DateTimePicker控件里面的显示的时间去掉,也就是我只要显示年/月/日

TextBox12.Text = DateTimePicker1.Value.ToString("yyyy/MM/dd")

这样格式化一下就可以了
