ACC: Using Automation to Print Microsoft Access Reports

• Microsoft Access versions 7.0, 97

SUMMARY

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

By carrying out the DoCmd object's OpenReport method, you can print Microsoft Access reports from any Automation client application, such as the Microsoft Visual Basic Programming System, Microsoft Excel, or Microsoft Project. This enables you to implement Microsoft Access as the reporting component in your application solutions.

NOTE: This article explains a technique demonstrated in the sample files, RptSampl.exe (for Microsoft Access for Windows 95 version 7.0) and RptSmp97.exe (for Microsoft Access 97). For information about how to obtain these sample files, please see the following articles in the Microsoft Knowledge Base:

MORE INFORMATION

This article assumes that you are familiar with Visual Basic for Applications and with creating Microsoft Access applications using the programming tools provided with Microsoft Access. For more information about Visual Basic for Applications, please refer to your version of the "Building Applications with Microsoft Access" manual.

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

NOTE: The following code is designed for the retail version of Microsoft Access. If you are using the run-time version of Microsoft 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 Debug window, and then press ENTER.

          ?OLEOpenReport("c:\MSOffice\Access\Samples\Northwind.mdb", _
                         "Invoice", strWhere:="OrderId = 10251")
   
   

NOTE: Make sure to supply the applicable path to files as defined on your system.
