Dymanic Reports

Does anybody have any examples for Dynamic Reports??

Meaning I have a report with Month/Year accross the top. ie. 1/2005,
2/2005, 3/2005, 4/2005.

If I change my date range the I would like the report to change its title to
2/2006, 3/2006, 4/2006, 5/2006 and so on.

My problem is how to you make a dynamic title header that changes with a
cross tab query grouped my month and year with field name change?

Thank you in advance for your help.

The titles can be changes by reading the criteria for the change from an
external source, such as a dialog form, but your example is not a title
change, it is a column header change. To do that you need to use code and
build columns for the maximum number of columns in the report. Not for the
faint at heart. Something like this from a working Xtab report:

Option Compare Database 'Use database order for string comparisons.
Option Explicit

' Constant for maximum number of columns qryResidence_XTab1 query would
' create plus 1 for a Totals column.
Const conTotalColumns = 13

' Variables for Database object and Recordset.
Dim dbsReport As Database
Dim rstReport As 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 Detail1_Format(Cancel As Integer, FormatCount As Integer)
' Place values in text boxes and hide unused text boxes.

Dim intX As Integer
' Verify that not at end of recordset.
If Not rstReport.EOF Then
' If FormatCount is 1, place 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 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 Detail1_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 = 2 To intColumnCount
' Starting at column 2 (first text box with crosstab value),
' compute total for current row in 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

' Place row total in text box in 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 Detail1_Retreat()

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

End Sub

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
Next intX

End Sub



Private Sub Report_Activate()

' Hide built-in Print Preview toolbar.
DoCmd.ShowToolbar "Print Preview", acToolbarNo

End Sub

Private Sub Report_Close()

On Error Resume Next

' Close recordset.
rstReport.Close

End Sub

' Show built-in Print Preview toolbar.

End Sub

Private Sub Report_NoData(Cancel As Integer)
MsgBox "No records match the criteria you entered.", vbExclamation, "No
Records Found"
rstReport.Close
Cancel = True
End Sub

Private Sub Report_Open(Cancel As Integer)

' Create underlying recordset for report using criteria entered in
' frmDateSelector form.

Dim intX As Integer
Dim qdf As QueryDef
Dim frm As Form

' Don't open report if frmDateSelector form isn't loaded.
If Not (IsLoaded("frmDateSelector")) Then
Cancel = True
MsgBox "To preview or print this report, you must open " _
& "frmDateSelector in Form view.", vbExclamation, _
"Must Open Dialog Box"
Exit Sub

' in frmDateSelector form.

' Open Recordset object.
Set rstReport = qdf.OpenRecordset()

' Set a variable to hold number of columns in crosstab query.
intColumnCount = rstReport.Fields.Count



End Sub

Private Sub ReportFooter4_Print(Cancel As Integer, PrintCount As Integer)

Dim intX As Integer

' Place column totals in text boxes in report footer.
' Start at column 2 (first text box with crosstab value).

' Hide unused text boxes in report footer.
For intX = intColumnCount + 2 To conTotalColumns
Me("Tot" + Format(intX)).Visible = False
Next intX
End Sub


Private Sub ReportHeader3_Format(Cancel As Integer, FormatCount As Integer)

' Move to first record in recordset at beginning of report
' or when report is restarted. (A report is restarted when
' you print a report from Print Preview window, or when you return
' to a previous page while previewing.)

'Initialize variables.

Dim intX As Integer

' Put column headings into text boxes in report header.

' Hide unused text boxes in report header.
For intX = (intColumnCount + 2) To conTotalColumns

End Sub

Private Function xtabCnulls(varX As Variant)

' Test if a value is null.
