How to make CDateTimeCtrl have a string as default value?

Question

I am using MFC CDateTimeCtrl in VS2010. It seems it always has a datetime value showed, default one is today. I want sort of customizing it. Would it be possible that to make it show a string say "no date selected" when it shows up first time? After that, when the end user picks up a date, show the corresponding date.

Thanks

Answer 1

基础控件支持“无值”，但显示一个复选框，允许指定（或不指定）数据。

可能您需要创建自己的自定义控件或将CDateTimeCtrl子类化并覆盖其行为
