Hi thanks for your advice. When I go to the General tab of the DTPicker Properties,it displays a blank screen. There is nothing for me to select. However, there is a CustomFormat in the Control Properties, please advise what should be written in it.

Perhaps the most useful property is Format that specifies how the data is displayed in the textbox portion of the control. There are three pre-defined formats that you can use or, by setting the Format to 3, you can specify your own format using the CustomFormat propertyL

Possible formats for the Date and Time Picker
Value Explanation
0 Long date as specified in the windows control panel. For example: Sunday, July 25, 2002
1 Short date as specified in the windows control panel. For example: 7/25/02
2 Time format. For example: 4:20 PM Note that even though only the time is displayed, the control’s value still contains the date portion of the value.
3 Custom. This setting allows you to specify your own custom format in the controls CustomFormat property

When the Date and Time Picker’s Format property is set to 3-Custom, you must specify the CustomFormat. This property defines the format expression that will be used to display the date in the textbox portion of the control. The following format strings are supported by the control.
