ACC2000: How to Use Automation to Print Microsoft Access Reports

• Microsoft Access 2000

SUMMARY

By carrying out the OpenReport method of the DoCmd object, you can print Access reports from any Automation client application, such as Microsoft Visual Basic or the Microsoft Visual Basic Environment (VBE). This enables you to implement Access as the reporting component in your application solutions. Microsoft provides programming examples for illustration only, without warranty either expressed or implied, including, but not limited to, the implied warranties of merchantability and/or fitness for a particular purpose. This article assumes that you are familiar with the programming language being demonstrated and the tools used to create and debug procedures. Microsoft support professionals can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific needs. If you have limited programming experience, you may want to contact a Microsoft Certified Solution Provider or the Microsoft fee-based consulting line at (800) 936-5200.

MORE INFORMATION

CAUTION: Following the steps in this example will modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and perform these steps on a copy of the database.

NOTE: The following code is designed for the retail version of Access. If you are using the run-time version of Access, please refer to the "Run-time Version of Microsoft Access" section later in this article.

Retail Version of Microsoft Access

1. Open Microsoft Access.



2. Create a new, blank database.



3. Create a module and type the following in the Declarations section:

   
   Option Explicit
   ' In other applications like Microsoft Visual Basic,
   ' you can include a reference to Microsoft Access to
   ' gain the use of Access constants. Or, use the following
   ' constant values...
   ' Global Const acNormal = 0
   ' Global Const acDesign = 1
   ' Global Const acPreview = 2
   ' -----------------------------------------------------
   ' Application Quit options...
   ' saves all objects without displaying a dialog box:
   ' Global Const acSaveYes = 0
   ' displays a dialog box that asks whether you want to save any
   ' database objects that have been changed but not saved:
   ' Global Const acPrompt = 1
   ' quits Microsoft Access without saving any objects:
   ' Global Const acExit = 2 




4. Type the following procedure:




Function OLEOpenReport(strDBName As String, _
                       strRptName As String, _
                       Optional ByVal intDisplay As Variant, _
                       Optional ByVal strFilter As Variant, _
                       Optional ByVal strWhere As Variant) As Boolean

   On Error GoTo OLEOpenReport_Err

   ' Create Automation object.
   Dim objAccess As Object
   Set objAccess = CreateObject("Access.Application")

   ' Open the supplied database.
   ' Optional parameter at the end of statement
   ' indicates exclusive mode if set to True...
   objAccess.OpenCurrentDatabase strDBName, False

   ' The OpenReport method uses the following arguments...
   ' Report Name - Name of the report object.
   ' View - Display in Print Preview or send to printer.
   '        acNormal - Print report
   '        acDesign - open report in design (n/a in runtime)
   '        acPreview - open in preview window
   ' Filter Name - Name of a saved filter query.
   ' Where Condition = valid SQL where condition.

   If IsMissing(intDisplay) Then intDisplay = acNormal
   If IsMissing(strFilter) Then strFilter = ""
   If IsMissing(strWhere) Then strWhere = ""
   objAccess.DoCmd.OpenReport strRptName, intDisplay, strFilter, _
      strWhere

   ' Close Microsoft Access session instance...
   objAccess.Quit acExit

   Set objAccess = Nothing
   OLEOpenReport = True
OLEOpenReport_End:
   Exit Function

OLEOpenReport_Err:
   MsgBox Error$(), vbInformation, "Automation"
   Resume OLEOpenReport_End
End Function
 

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




?OLEOpenReport("c:\Program Files\Microsoft Office\Office\Samples\Northwind.mdb", "Invoice", strWhere:="OrderId = 10251") 

Run-Time Version of Microsoft Access

1. Open Microsoft Access.



2. Create a new database.

4. Type the following procedure:




Function OLEOpenReportRuntime(strDBName As String, _
strRptName As String, _

Optional ByVal strFilter As Variant, _
Optional ByVal strWhere As Variant _
) As Boolean

On Error GoTo OLEOpenReportRuntime_Err
