Calculation of date variables with IF statements part 2

I am still having trouble converting an unbound field "txtRptPD" to a calculated start and end date (dtStart & dtEnd) depending on the value of another variable "vType"

I have a "msgbox" pop up after I update the vType variable to make sure it has a value:
Private Sub lstEval_AfterUpdate()
 Dim vType As String
     vType = Trim(Me.LstEval.Column(0) & "")

     MsgBox vType & ""  '<--------Does this display a value?
 End Sub

Open in new window


After I update the "txtRptPD" field I have another msgbox pop up to show me the "dtRpt" variable show.  Then I have a msgbox open to show the "dtStart" & "dtEnd" values.

The dtRpt value is good.  However, the dtStart and dtEnd shows a time 12:00:00 AM.

Below is the code to calculate and then show the dtRpt, dtStart and dtEnd values:

Private Sub txtRptPD_AfterUpdate()
 Dim dtEnd As Date
 Dim dtStart As Date
 Dim dtRpt As Date
 dtRpt = Me.txtRptPD
     

 

If vType = "Advancement" Then
     dtStart = Format(DateSerial(Year(DateAdd("m", -7, dtRpt)), Month(DateAdd("m", -7, dtRpt)), 1), "mm/dd/yyyy")
     dtEnd = Format(DateAdd("d", -1, DateSerial(Year(dtRpt), Month(dtRpt), 1)), "mm/dd/yyyy")
 End If

 If vType = "Reappointment" Then
     dtStart = Format(DateSerial(Year(DateAdd("m", -25, dtRpt)), Month(DateAdd("m", -25, dtRpt)), 1), "mm/dd//yyyy")
     dtEnd = Format(DateAdd("d", -1, DateSerial(Year(dtRpt), Month(dtRpt), 1)), "mm/dd/yyyy")
 End If

    MsgBox dtRpt & ""  '<--------Does this display a value?
     MsgBox dtStart & ""
     MsgBox dtEnd & ""
 End Sub 

Open in new window

Can someone look at the Calculation code and give me  a suggestion on how to store the correct values to dtStart and dtEnd?

Thanks

Glen

That said... a better solution would be to remove the listbox after update event and simply use this (unless there is more code not shown here in lstEval_AfterUpdate that uses vType) :


Private Sub txtRptPD_AfterUpdate()
 Dim dtEnd As Date
 Dim dtStart As Date
 Dim dtRpt As Date


 Dim vType As String
     vType = Trim(Me.LstEval.Column(0) & "")


 dtRpt = Me.txtRptPD
     

 

If vType = "Advancement" Then
     dtStart = Format(DateSerial(Year(DateAdd("m", -7, dtRpt)), Month(DateAdd("m", -7, dtRpt)), 1), "mm/dd/yyyy")
     dtEnd = Format(DateAdd("d", -1, DateSerial(Year(dtRpt), Month(dtRpt), 1)), "mm/dd/yyyy")
 End If

 If vType = "Reappointment" Then
     dtStart = Format(DateSerial(Year(DateAdd("m", -25, dtRpt)), Month(DateAdd("m", -25, dtRpt)), 1), "mm/dd//yyyy")
     dtEnd = Format(DateAdd("d", -1, DateSerial(Year(dtRpt), Month(dtRpt), 1)), "mm/dd/yyyy")
 End If

    MsgBox dtRpt & ""  '<--------Does this display a value?
     MsgBox dtStart & ""
     MsgBox dtEnd & ""
 End Sub

Your vType variable is seen in the first sub, but it is local to that sub, and not seen in the second.

>>> Dim vType As String

Try moving this line of code from lstEval_AfterUpdate to the very top of the code behind your form, immediately under Option Compare Database and Option Explicit (which you should add if it is not in your code already):

Option COmpare Database
Option Explicit

Dim vType As String

Open in new window


Placing it at the top of your form's module makes it visible to all of the procedures in that module.

You were right about the enhancement.

When I ran it before making the vType adjustment, vtype was not recognized.

After I moved it down, worked  like a charm.

thanks
