2 questions about ComboBox

Hi,
Let's say that I have two comboboxes named cboDay and cboMonth.

1) Let's say i want to type something into my combobox and when i click enter, i want that text that i typed to be automatically added to the list. So the next time i drop down my combobox, i want that text to be in the list.
I already set dropDownStyle to DropDown. If i have to type a code for that, could you please tell me in what procedure to write it?
cboDay_KeyPress? cboDay_Enter?

2)cboMonth has months of the year from 1 to 12. CboDays initially has numbers from 1 to 31. But not all the months has same number of days.
How will i make it so that if user clicks 2 from cboMonth, days in cboDay will remove 30 and 31 from the list? (February may have 29 days but not 30 and 31.) And when user clicks 3 from cboMonth , 30 and 31 will be added to cboDays list.
Is it gonna be something like,
 if cboMonth.selectedIndex = 1 then
      cboMonth.Items.Remove(29)
      cboMonth.Items.Remove(30)
 endIf

Thanks

At KeyPress Check for

e.KeyChar.GetHashCode  it is 851981 for Enter.

B>>>

You Add the days at run time only first check the month and then add item in the combo through a loop.

create three conditions for 28 , 30, 31  Also 29 if consider leep year .

Part A works, but can you be more spesific on part b?
What is the procedure to create those conditions? It would be nice if you could write the exact code.
Thanks

try like this way


Dim i As Integer
        Select Case (cboMonth.Text)
            Case 1, 3, 5, 7, 8, 10, 12
                For i = 1 To 31
                    cboDay.Items.Add(i)
                Next
            Case 2
                For i = 1 To 28
                    cboDay.Items.Add(i)
                Next
            Case 4, 6, 9, 11
                For i = 1 To 30
                    cboDay.Items.Add(i)
                Next
            Case Else

        End Select
