One function for All multi-select List Boxes

I hate writing the same code over and over like the code that loops through the items selected in a multi-select list box. This function will accept a list box control as an arguement and return syntax like:
" AND [ColorField] In ('Red', 'Black', 'Green') "
It expects a specific format of your list box name. If no items are selected the function returns a zero length string. Save this function in a standard module. Don't name the module the same as the function name.

A typical method of using this would be:
Dim strWhere as String
strWhere = " 1=1 "
strWhere = strWhere & BuildIn(Me.lboTColor)
strWhere = strWhere & BuildIn(Me.lboNEmpID)
DoCmd.OpenReport "rptA", acViewPreview, , strWhere

Function BuildIn(lboListBox As ListBox) As String
'send in a list box control object
' the list box name must begin with _
"lbo" and be followed by one character describing the data type _
"T" for Text _
"N" for Numeric or _
"D" for Date and then the 5th characters on for the _
field name ie: lboEmployeeID
Dim strIn As String
Dim varItem As Variant
Dim strDelim 'used for delimiter
'Set the delimiter used in the IN (...) clause
Select Case Mid(lboListBox.Name, 4, 1)
Case "T" 'text data type
strDelim = "'" 'double quote
Case "N" 'numeric data type
strDelim = ""
Case "D" 'Date data type
strDelim = "#"
End Select

If lboListBox.ItemsSelected.Count > 0 Then
strIn = " AND [" & Mid(lboListBox.Name, 5) & "] In ("
For Each varItem In lboListBox.ItemsSelected
strIn = strIn & strDelim & lboListBox.ItemData(varItem) & strDelim & ", "
Next
'remove the last ", " and add the ")"
strIn = Left(strIn, Len(strIn) - 2) & ") "
End If
BuildIn = strIn

End Function

You could also add arguments to the function that contain the Field Name and Field Delimiter rather than storing these two pieces of information in the listbox control name. The function might then look like

Function BuildIn(lboListBox As ListBox, _
strField as String, strDelimiter as String) _
As String
'etc
A call to the function could be:

strWhere = strWhere & _
(BuildInMe.lboColor, "Color", """" )
