Calendar problem

[Patrick Simonds]

I have a dialog box which contains 4 Calendars. The 4 calendars are set up
so that when you click on the 2nd or 4th Tuesday of the first calendar the
other calendars would progressively show the next Tuesday which was 2 weeks
away, see code below.

It turns out that what I need to have happen, is that if I select the 2nd
Tuesday (say of September) on Calendar1 then Calendar2 should have the 4th
Tuesday of September selected, Calendar3 the second Tuesday of October and
Calendar4 would display the 4th Tuesday of October. Of course if I had
started with the 4th Tuesday of September the I would need the 2nd Tuesday
of October and so on.

So it is obvious my code can not do this, so does anyone have an idea how I
might make this work?



Private Sub Calendar1_Click()

Calendar2 = Calendar1 + 14
Calendar3 = Calendar1 + 28
Calendar4 = Calendar1 + 42

End Sub

Hi Patrick,

Tuesday (say of September) on Calendar1 then Calendar2 should have the 4th
Tuesday of September selected, Calendar3 the second Tuesday of October and
Calendar4 would display the 4th Tuesday of October. Of course if I had
started with the 4th Tuesday of September the I would need the 2nd Tuesday
of October and so on.

Your code responded in precisely the above manner for me.

What dates were displayed in your dependent calendar controls?

 

[Patrick Simonds]

You are right (based on the starting point I provided). I should have used a
better example. If you were to start with the second Tuesday of March on
Calendar1, when you got to Calendar3 you would be on the 1st Tuesday of
April and Calendar4 would be on the 3rd Tuesday of April.

Hi Patrick! You can also use the DateAdd function:


Code:
--------------------
Private Sub Calendar1_Click()
Calendar2.Value = DateAdd("ww", 2, Calendar1.Value)
Calendar3.Value = DateAdd("ww", 2, Calendar2.Value)
Calendar4.Value = DateAdd("ww", 2, Calendar3.Value)
End Sub

Try the following (lightly tested!):

'======================>>
Private Sub Calendar1_Click()
Dim YR As Long
Dim MTH As Long
Dim SecondTues As Double
Dim bValidDate

YR = Year(Calendar1)
MTH = month(Calendar1)

SecondTues = Evaluate("=DATE(" & YR & "," & MTH _
& ",15)-WEEKDAY(DATE(" & YR & "," & MTH & ",5))")

If Calendar1 <> SecondTues And Calendar1 <> SecondTues + 14 Then
'Neither 2nd nor 4th Tuesday selected!
MsgBox "The first calendar selection should be either the " _
& "SECOND or FOURTH TUESDAY in the selected month!"
'Reset each calendar to today's date!
Calendar1.Value = Date: Calendar2 = Date
Calendar3 = Date: Calendar4 = Date
Else
'Calendar1 selection is 2nd or 4th Tuesday!
bValidDate = True
End If

If bValidDate Then
If Day(Calendar1) <= 14 Then
'Second Tuesday selected
Calendar2 = Evaluate("=DATE(" & YR & "," & MTH _
& ",29)-WEEKDAY(DATE(" & YR & "," _
& MTH & ",5))")
Calendar3 = Evaluate("=DATE(" & YR & "," & MTH + 1 _
& ",15)-WEEKDAY(DATE(" & YR & "," & MTH + 1 & ",5))")
Calendar4 = Evaluate("=DATE(" & YR & "," & MTH + 1 _
& ",29)-WEEKDAY(DATE(" & YR & "," & MTH + 1 & ",5))")

Else
'Fourth Tuesday selected
Calendar2 = Evaluate("=DATE(" & YR & "," & MTH + 1 _
& ",15)-WEEKDAY(DATE(" & YR & "," & MTH + 1 & ",5))")
Calendar3 = Evaluate("=DATE(" & YR & "," & MTH + 1 _
& ",29)-WEEKDAY(DATE(" & YR & "," & MTH + 1 & ",5))")
Calendar4 = Evaluate("=DATE(" & YR & "," & MTH + 2 _
& ",15)-WEEKDAY(DATE(" & YR & "," & MTH + 2 & ",5))")
End If
End If

End Sub

Private Sub Calendar1_Click()
Dim date1 As Date
Dim date2 As Date
date1 = DateSerial(Calendar1.Year, Calendar1.Month, 1)
Do Until Weekday(date1, vbMonday) = 2
date1 = date1 + 1
Loop
date1 = date1 + 7 'set 2nd Tuesdaye
date2 = date1 + 14 '4th tuesday

Select Case Calendar1.Value
Case date1
Calendar2.Value = Calendar1.Value + 14
Calendar3.Value = Calendar1 + 28
Calendar4.Value = Calendar1.Value + 42
Case date2
Calendar2.Value = date1 + 28
Calendar3.Value = Calendar1 + 28
Calendar4.Value = Calendar2 + 28
Case Else

End Select


End Sub

All that seems to do is move me ahead two weeks. That is not what I need.

of April and so on."

Thanks for the try, but that does not seem to work either.

If you try this staring with the second week of March (2005) you will see
that in April it is the first and third Tuesday selected.
