ACC2000: How to Generate and Print a Report Without Saving It

ID: Q203992

The information in this article applies to:

Microsoft Access 2000

Advanced: Requires expert coding, interoperability, and multiuser skills.

This article applies to a Microsoft Access database (.mdb) and a Microsoft Access project (.adp).

SUMMARY

You may have occasion to produce a report, which afterwards you don't want to save. Examples include reporting on a user's responses from a custom wizard or a report on database information, such as record sources that may cause problems with security settings. The reason you would want to delete the report rather than to save it is because you would add to the size of the database file with each save action. This article shows you how to create such a report.

The following sample code does the following:

It creates and populates a simple array.
It creates a simple report and creates event procedures.
It prints the array to the report.
It discards the report without saving it.

For the sake of simplicity, the data in this example will be supplied from a single dimension array and the output report will have just one data field.

Create a new database.

Create a module and type the following lines in the Declarations section if they are not already there:


Option Compare Database
Option Explicit
Public arySampleData() As Variant
Public strReportName As String

Type the following procedure:


Public Sub FillArray()
   Dim aryItem As Long
   For aryItem = 0 To 9
      ReDim Preserve arySampleData(aryItem)
      arySampleData(aryItem) = "Item " & aryItem
   Next aryItem
End Sub

Type the following procedure:


Sub TempReport()
  Dim rpt As Report
  Dim mdl As Module
  Dim strCode As String
  Dim lngReturn As Long
  Dim ctlLabel1 As Control, ctlText1 As Control
  Dim intDataX As Integer, intDataY As Integer
  Dim intLineCount As Integer, intCounter As Integer

  ' Turn off the screen updating. Comment this line out during
  ' testing because it prevents user interaction if the code fails.
  Application.Echo False

  ' Create new report and store the name.
  Set rpt = CreateReport
  strReportName = rpt.Name

  ' Expose the report header.
  DoCmd.RunCommand acCmdReportHdrFtr
  Set mdl = rpt.Module

  intLineCount = mdl.CountOfLines
  strCode = "Dim intCounter as Integer"
  mdl.InsertLines intLineCount, strCode

  lngReturn = mdl.CreateEventProc("Print", rpt.Section(acHeader).Name)
  strCode = "intCounter=0" & vbCrLf & "FillArray"
  mdl.InsertLines lngReturn + 1, strCode

  lngReturn = mdl.CreateEventProc("Print", rpt.Section(acDetail).Name)
  strCode = "Me!txtTest.Value= arySampleData(intCounter)" & vbCrLf
  strCode = strCode & "Me!lblTest.Caption= ""Array Value""" & vbCrLf
  strCode = strCode & "If intCounter <> UBound(arySampleData)" _
     & "Then Me.nextrecord=False" & vbCrLf
  strCode = strCode & "intCounter=intCounter+1"
  mdl.InsertLines lngReturn + 1, strCode

  ' Set positioning values for report controls.
  ' Measurements are in twips.
  intDataX = 500
  intDataY = 50

  ' Create unbound default-size label and text box in detail section.
  rpt.Section(acDetail).Height = 400
  Set ctlLabel1 = CreateReportControl(reportname:=strReportName, _
     ControlType:=acLabel, Left:=intDataX, Top:=intDataY, _
     Width:=1440, Height:=240)
  ctlLabel1.Name = "lblTest"
  Set ctlText1 = CreateReportControl(reportname:=strReportName, _
     ControlType:=acTextBox, Left:=(intDataX + 1440), Top:=intDataY)
  ctlText1.Name = "txtTest"

  ' Turn the screen back on.
  Application.Echo True
End Sub

Type the following function:


Function BuildReport()
  ' Call the TempReport procedure.
  TempReport

  ' Print the report without showing it in preview mode.
  DoCmd.OpenReport strReportName, acViewNormal

  ' Close the report without saving it.
  DoCmd.Close acReport, strReportName, acSaveNo
End Function

To test this function, type the following line in the Immediate window, and then press ENTER:


?BuildReport()

Note that the report is printed, and then the report no longer exists. Also note that the variable, intCounter, is initialized and the function, FillArray, is called from the Print event of the ReportHeader section rather than from the Open event of the Report, which would cause the example to fail.
