DateTimePicker validation
提问by user1670625
I want to validate the DateTimePicker control in vb.net. I am using it for date of joining for the employee so i dont want the control to allow selection of future dates..only dates till the current date can be allowed to select. I have tried the following code:
我想验证 vb.net 中的 DateTimePicker 控件。我将它用于员工的加入日期，所以我不希望控件允许选择未来日期..只能允许选择当前日期之前的日期。我尝试了以下代码：
Private Sub DateTimePickerDOJ_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePickerDOJ.ValueChanged
If DateTimePickerDOJ.Value > Date.Today Then
MessageBox.Show("You Cannot Select a Future Date!", "", MessageBoxButtons.OK, MessageBoxIcon.Error)
End If
End Sub
The above code only displays the message correctly but its of no use becoz the future date is getting selected.
上面的代码只正确显示消息，但它没有用，因为选择了未来的日期。

You can use the DateTimePicker.MaxDateproperty to achieve that.
您可以使用DateTimePicker.MaxDate属性来实现这一点。
"Gets or sets the maximum date and time that can be selected in the control."
“获取或设置可以在控件中选择的最大日期和时间。”
