Select Case

VBA Select Case statement is one of the most useful Access VB tools used to program MS Access forms and reports. The select case visual basic command takes the place of multiple nested if statements and makes your VB code clean and much easier to follow by neatly handling the conditional flow of your VBA programming code. The syntax of the Access Case statement is:

Select Case Expression
    Case Expression_1
        Statement_1
    Case Expression_2
        Statement_2
    Case Expression_n
        Statement_n
    ...
End Select

Where Expression is a variable passed to the subroutine or a field on a form or within a recordset.

And Expression_1 to n are either constants, ranges of values, series of values, or calculations which resolve to a value for each Case.  You can also use alphanumeric comparisons in both the main Expression and the conditional Expressions (1..n).

In the VBA Select Case statement example below we have a report parameter form that has three choices for report output options:

1 - Label report
2 - Datasheet view of query results
3 - A series of statements to prepare an address file

Here is the example Access Case statement used in visual basic code:

Private Sub Command5_Click()
Dim pitney As String
Dim sqltext As String
Dim rst As DAO.Recordset
Dim db As DAO.Database
Dim stDocName As String

On Error GoTo Err_Command5_Click

Select Case Me.Output_Options
    Case 1
        stDocName = "R_Daily_Prospect_Labels"
        DoCmd.OpenReport stDocName, acPreview
    Case 2
        DoCmd.OpenQuery "Q_Daily_Prospect_Labels"
    Case 3
        Set db = CurrentDb
        pitney = DLookup("Path", "Q_path_Pitney", 1 = 1)
        pitney = Replace(pitney, "/", "\")
        pitney = Replace(pitney & "\", "\\", "\")
        pitney = pitney & "pitneybowes.mdb"
        DoCmd.RunSQL "delete * from mailmerge in '" & pitney & "'"

        sqltext = "INSERT INTO mailmerge (name,address1,address2,city,state,zip) in '" & pitney & "'" & _
        " select name,address1,address2,city,state,zip from q_daily_prospect_Pitney"

        DoCmd.RunSQL (sqltext)
        Set rst = db.OpenRecordset("select count(name) as icount from mailmerge in '" & pitney & "'")
        rst.MoveFirst
        MsgBox "A total of " & Nz(rst!Icount, 0) & " records were inserted into " & pitney
        rst.Close
        Set rst = Nothing
End Select

Call Mark_As_Sent_Click
Exit_Command5_Click:
Exit Sub

Err_Command5_Click:
MsgBox Err.Description
Resume Exit_Command5_Click

End Sub
