ACC95: Incorrect GetAccessReportList in "Building Applications"

• Microsoft Access 7.0
• Microsoft Excel for Windows, versions 5.0, 7.0

SYMPTOMS

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

The GetAccessReportList procedure on page 288 of the "Building Applications with Microsoft Access for Windows 95" manual causes the error "Object doesn't support this property or method." (run-time error 438)

CAUSE

This procedure refers to a variable called "dbs" but fails to declare and set this variable. Also, the "and" condition on the first If statement refers to "mdb" but should refer to "mda." Finally, the text argument of the AddItem method should be specified as a named argument.

RESOLUTION

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 the "Building Applications with Microsoft Access for Windows 95" manual.

The following steps show how to use the GetAccessReportList procedure in Microsoft Excel. The corrected GetAccessReportList procedure is included in these steps:

1. Start Microsoft Excel (version 5.0 or later).



2. On the Insert menu, select Macro, and then click Module to create a new module within the workbook.



3. Type the following code in the module, which includes the corrected GetAccessReportList procedure:

   
          Option Explicit
   
          Dim objAccess As Object
   
          Sub GetAccessReportList()
            Dim dbs As Object
            Dim strDBName As String
            Dim intReport As Integer
   
            Set objAccess = CreateObject("Access.Application.7")
   
            strDBName = DialogSheets(1).EditBoxes(1).Text
            If Right$(strDBName, 4) <> ".mdb" And _
              Right$(strDBName, 4) <> ".mda" Then
              strDBName = strDBName & ".mdb"
            End If
   
            With objAccess
              .OpenCurrentDatabase (strDBName)
              Set dbs = .DBengine(0)(0)
              With dbs.Containers("Reports")
                For intReport = 0 To .Documents.Count - 1
                  If Left$(.Documents(intReport).Name, 4) <> "~TMP" Then
                    DialogSheets(1).ListBoxes(1).AddItem Text:= _
                      .Documents(intReport).Name
                  End If
                Next intReport
              End With
            End With
          End Sub
   
          Sub Main()
            DialogSheets(1).ListBoxes(1).RemoveAllItems
            DialogSheets(1).Show
          End Sub 




4. On the Insert menu, select Macro, and then click Dialog to create a new dialog within the workbook.



5. Use the Edit Box button from the Forms toolbox to draw an edit box inside the Dialog frame. (After clicking the Edit Box button, you must click and drag inside the Dialog frame to draw the edit box.)



6. Use the List Box button to draw a list box inside the Dialog frame.



7. Using the right mouse button, click OK within the Dialog frame, and then click Format Object on the menu that appears.



8. Click to clear the Dismiss check box, and then click OK.



9. Using the right mouse button, click OK within the Dialog frame, and then click Assign Macro on the menu that appears.



10. Select GetAccessReportList and click OK.



11. Click the Sheet1 tab to activate a worksheet within the workbook.



12. On the Tools menu, click Macro.



13. Select Main and click Run. Your custom dialog box should appear.



14. Type a valid path and database name in the edit box and click OK, for example:

    C:\Msoffice\Access\Samples\Northwind.mdb

Alternative GetAccessReportList Procedure

      Sub GetAccessReportList()
     Dim lstReports As list box
     Dim strDBName As String
     Dim intReport As Integer
     Dim docReports As Object
     Dim intCount As Integer
     Dim strDoc As String

     Set lstReports = DialogSheets(1).ListBoxes(1)
     Set objAccess = CreateObject("Access.Application.7")

     strDBName = DialogSheets(1).EditBoxes(1).Text
     If Right$(strDBName, 4) <> ".mdb" And _
       Right$(strDBName, 4) <> ".mda" Then
       strDBName = strDBName & ".mdb"
     End If

     objAccess.OpenCurrentDatabase strDBName
     With objAccess.DBengine(0)(0)
       Set docReports = .Containers("Reports").Documents
       intCount = docReports.Count - 1
       For intReport = 0 To intCount
         strDoc = docReports.Item(intReport).Name
         If Left$(strDoc, 4) <> "~TMP" Then
           lstReports.AddItem Text:=strDoc
         End If
       Next
     End With
   End Sub
