# Removing items from a combo box

I have 2 combo boxes, combo1 and combo 2. They display the date. I need it so that if say February is selcted in combo 1 then the number 31 is removed from combo 2 because you obviously cant have the 31st of february.

Cheers

This builds your first combo values using the vb date functions and then in the click event of the month combo box - combo1, this rebuilds the number of days in combo2 based on the month.

Private Sub Combo1_Click()
Dim i As Integer

Dim dteCurDate As Date

Me.Combo2.Clear

dteCurDate = Me.Combo1.ItemData(Me.Combo1.ListIndex) & "/1/" & Format(Now, "yyyy")
Do Until Format(dteCurDate, "mmmm") <> Me.Combo1.Text
DoEvents
Loop

If Me.Combo2.ListCount > 0 Then Me.Combo2.ListIndex = 0
End Sub

Dim i As Integer
Dim dteCurDate As Date

dteCurDate = "01/01/" & Format(Now, "yyyy")
For i = 0 To 11
Me.Combo1.ItemData(i) = i + 1
Next i

Me.Combo1.ListIndex = 0

End Sub

Here's a couple of simple subs that will load your two combo's starting with the current month & year (in cbomth) and populate the second one(cboday) with the max number of days for that month...fully respecting leap-years...

Private Sub cboMth_Click()

Dim d As Integer
Dim strdate As String
strdate = DateAdd("m", 1, cboMth.Text & " 01")

cboDay.Clear
For d = 0 To Day(DateAdd("d", -1, strdate)) - 1
Next d

End Sub

Dim m As Integer

cboMth.Clear
cboDay.Clear

strDte = Format(Now, "mmm yyyy")
For m = 0 To 11
Next m

End Sub

To alter mine to start from the current month and to include year - the same results as dmang, it is only five line changes.  Here is my above code example, but with those five changes:

Private Sub Combo1_Click()
Dim i As Integer

Dim dteCurDate As Date

Me.Combo2.Clear

dteCurDate = Me.Combo1.ItemData(Me.Combo1.ListIndex) & "/1/" & Right(Me.Combo1.Text, 4)
Do Until Format(dteCurDate, "mmmm yyyy") <> Me.Combo1.Text
DoEvents
Loop

If Me.Combo2.ListCount > 0 Then Me.Combo2.ListIndex = 0
End Sub

Dim i As Integer
Dim dteCurDate As Date

dteCurDate = Format(Now, "mm") & "/01/" & Format(Now, "yyyy")
For i = 0 To 11
Me.Combo1.ItemData(i) = Format(DateAdd("m", i, dteCurDate), "m")
Next i

Me.Combo1.ListIndex = 0

End Sub
