我试图这样做,当用户按下按钮时,会显示一个DateTimePicker对话框,我甚至想得到他们选择的结果日期。这是我到目前为止所做的:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Dis As System.Windows.Forms.DateTimePicker = New System.Windows.Forms.DateTimePicker()
' Set the MinDate and MaxDate.
Dis.MinDate = New DateTime(1985, 6, 20)
Dis.MaxDate = DateTime.Today
' Set the CustomFormat string.
Dis.CustomFormat = "MMMM dd, yyyy - dddd"
Dis.Format = Windows.Forms.DateTimePickerFormat.Custom
' Show the CheckBox and display the control as an up-down control.
Dis.ShowCheckBox = True
Dis.ShowUpDown = True
Dis.Show()
End Sub
但是当我按下按钮并运行代码时,没有任何内容显示出来。我认为应该有一种简单地以编程方式显示此对话框的方法。有人可以帮我吗? : - )
仅供参考,我在VB 2010中对此进行编码,如果这有帮助吗? : - \

在vb.net中,DateTimePicker
不是OpenFileDialog, SaveFileDialog, PrintDialog
或其他类似对话框的对话框。
尽管它的'弹出'外观,DateTimePicker
是一个控制对象,因此它必须放在(添加到)窗体或窗口之后才能显示和使用。

我做了什么,是我做了一个按钮,打开了一个单独的表单,我看起来像一个对话框,并打开DateTimePicker
。这是我能想出怎样做的最好的解决方法。

向您的项目添加一个表单,使其与日历或日期选择器控件的大小相同。我使用了日历:
Public Class frmDatePicker
Private _Selected As Date
Public Property Selected As Date
Get
Return _Selected
End Get
Set(value As Date)
_Selected = value
End Set
End Property
Private Sub calPickDate_DateChanged(sender As Object, e As DateRangeEventArgs) Handles calPickDate.DateChanged
Selected = calPickDate.SelectionStart
End Sub
End Class
要使用它:
Dim varDate As String = ""
Dim frm As frmDatePicker = New frmDatePicker()
frm.ShowDialog()
varDate = frm.Selected.ToString()
frm.Dispose()
'Do something with varDate
