Yeah I can understand why you will be best falling back to your usual date picker.

Personally I use the DTPicker from the "Microsoft Windows Common Controls-2 6.0 (SP6)" for the reasons I said above, which can be seen in my other post: http://forum.codejock.com/forum_posts.asp?TID=17827

Thanks, that works but im using it in a form that has several instances of it plus a host of other controls.

I'll fallback to my usual date picker I think.

Hi stuc,

Yeah I know about the lack of the keydown, keypress & keyup on the DateTimePicker. I rarely use it due to the way it skins (you can't see the day text clearly in some instances). However as a workaround why don't you try this:

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vKey As Long) As Integer

Private Const VK_DELETE = &H2E

Private Sub Form_Load()
    With DateTimePicker
        .Value = Format$(Date, "dd/mm/yyyy")
        .Format = xtpPickerCustom
        .CustomFormat = " "
    End With
End Sub

Private Sub DateTimePicker_CloseUp()
    DateTimePicker.Format = xtpPickerShortDate
End Sub

Private Sub Timer_Timer()
    If CBool(GetAsyncKeyState(VK_DELETE)) Then
        With DateTimePicker
            .Value = Format$(Date, "dd/mm/yyyy")
            .Format = xtpPickerCustom
            .CustomFormat = " "
        End With
    End If
End Sub

Set the timer to be 100 milliseconds, it's crude but works well.

Thanks fo rthe reply. This works ok for when the field is first on the screen but I cant trap the delete key for when the user wants to delete the date.

I dont really want to have to put a "delete" button on screen to clear the field.

Hi,

I found a piece of code I had posted a while back in the Controls forum on this.

Private Sub Form_Load()
    With dtpDateOfRequest
        .Value = Format$(Date, "dd/mm/yyyy")
        .Format = xtpPickerCustom
        .CustomFormat = " "
    End With
End Sub

Private Sub dtpDateOfRequest_CloseUp()
    dtpDateOfRequest.Format = xtpPickerShortDate
End Sub

Yes it can, use the Custom setting that way you can then set the date field as blank. I am not in the office so can't post a code snippet, however if nobody else does I will post it on Monday morning.

I'd like to use the datetimepicker as a data entry field but the users must be able to leave the date empty?

Can this be done ?
