dynamic crosstab report with groupfooter totals

[aeg]

Hi
I am trying to generate a crostab report but becuase the cloumn heading are
changing based on the user selection, I had to generate the report
headings/totals dynamically. I found the code below on microsoft site which
works for most of the things i wanted to do (with slight modifications).
However i couldn't work out how to addd sub-totals to my GroupFooter.

Any help/comments greatly appreciated.

Option Compare Database
Option Explicit

' Constant for maximum number of columns
' create plus 1 for a Totals column.
Const conTotalColumns = 11

' Variables for Database object and Recordset.
Dim dbsReport As DAO.Database
Dim rstReport As DAO.Recordset

' Variables for number of columns and row and report totals.
Dim intColumnCount As Integer

Dim lngRgColumnTotal(1 To conTotalColumns) As Long
Dim lngReportTotal As Long


Private Sub InitVars()

Dim intX As Integer

' Initialize lngReportTotal variable.
lngReportTotal = 0

' Initialize array that stores column totals.
For intX = 1 To conTotalColumns
lngRgColumnTotal(intX) = 0
'Debug.Print lngRgColumnTotal(intX)
Next intX

End Sub


Private Function xtabCnulls(varX As Variant)

'Debug.Print varX
' Test if a value is null.
If IsNull(varX) Then
' If varX is null, set varX to 0.
xtabCnulls = 0
Else
' Otherwise, return varX.
xtabCnulls = varX
End If

End Function


Private Sub Detail_Format(Cancel As Integer, FormatCount As Integer)
' Put values in text boxes and hide unused text boxes.

Dim intX As Integer
' Verify that you are not at end of recordset.
If Not rstReport.EOF Then
' If FormatCount is 1, put values from recordset into text boxes
' in "Detail" section.
If Me.FormatCount = 1 Then
For intX = 1 To intColumnCount
' Convert Null values to 0.
Me("Col" + Format(intX)) = xtabCnulls(rstReport(intX - 1))
Next intX

' Hide unused text boxes in the "Detail" section.
For intX = intColumnCount + 2 To conTotalColumns
Me("Col" + Format(intX)).Visible = False
Next intX

' Move to next record in recordset.
rstReport.MoveNext
End If
End If

End Sub


Private Sub Detail_Print(Cancel As Integer, PrintCount As Integer)

Dim intX As Integer
Dim lngRowTotal As Long

' If PrintCount is 1, initialize rowTotal variable.
' Add to column totals.
If Me.PrintCount = 1 Then

lngRowTotal = 0

For intX = 3 To intColumnCount
' Starting at column 2 (first text box with crosstab value),
' compute total for current row in the "Detail" section.
lngRowTotal = lngRowTotal + Me("Col" + Format(intX))

' Add crosstab value to total for current column.
lngRgColumnTotal(intX) = lngRgColumnTotal(intX) + Me("Col" +
Format(intX))

Next intX

' Put row total in text box in the "Detail" section.
Me("Col" + Format(intColumnCount + 1)) = lngRowTotal
' Add row total for current row to grand total.
lngReportTotal = lngReportTotal + lngRowTotal
End If
End Sub


Private Sub Detail_Retreat()

' Always back up to previous record when "Detail" section retreats.
rstReport.MovePrevious

End Sub


Private Sub GroupFooter0_Print(Cancel As Integer, PrintCount As Integer)

'some code to go in here to populate the group footer totals


End Sub


Private Sub PageHeaderSection_Format(Cancel As Integer, FormatCount As
Integer)

Dim intX As Integer

' Put column headings into text boxes in page header.
For intX = 1 To intColumnCount

' Hide unused text boxes in page header.

Next intX

End Sub

Maybe you can initialize a counter to 0 in the GroupHeader, sum the
individual value in the Print event of the Group detail to the counter, and
display what is in the counter in the print event of the GroupFooter. Sure,
you can define 'n' counters, one per column, or an array of 'n' counters, if
you have to cumulate 'n' columns. Using the print event of the detail seems
to make irrelevant to consider the possible 'Retreat' actions (you will have
to if you were using the Format event of the details section).
