[RESOLVED] [2005] Set Value of Each DateTimePicker In a Groupbox

Hello,

I have several DateTimePickers on my form (formatted as time) and would like to populate each of them based on the current hour.
e.g. If I open the form at 10:22 AM I would lke the datetimepickers to show 10:00.

In my own mind, the code below is the sort of thing I'm after :

Code:

---

Dim d As DateTimePicker
For Each d In GroupBox1
    d.Value = Date.Today & " " & Hour(Now) & ":00"
Next

---

However I get a message about groupbox1 not being a collection type.
I assume there is a way of doing what I want ?

Put something like this in your form load event handler

Code:

---

Dim time As Date = DateTime.Now.AddMinutes(-DateTime.Now.Minute)
        Dim DTP As DateTimePicker = Nothing
        For Each ctrl As Control In Me.GroupBox1.Controls
            If TypeOf ctrl Is DateTimePicker Then
                DTP = DirectCast(ctrl, DateTimePicker)
                DTP.Value = time
            End If
        Next

---

This:

vb.net Code:

Dim time As Date = DateTime.Now.AddMinutes(-DateTime.Now.Minute)

doesn't allow for seconds and milliseconds. This would be better:

vb.net Code:

Dim time As Date = DateTime.Today.AddHours(DateTime.Now.Hour)

What?! :confused: Care to explain?

The first code rounds the minutes but leaves the seconds and milliseconds so you don't get the even hour. My code gives you the even hour.

Thank you both very much - I appreciate it.
