SUMMARY

This article demonstrates how to use the PivotTable Office Web Component to display information on a Visual Basic form.

MORE INFORMATION

The Office Web Components are a set of controls that enable browsing of Office data. Because the Web Components are controls, you can place them on a Visual Basic form and automate the components to display data.

Building the Automation Sample

  1. Start Visual Basic and create a new standard EXE project. Form1 is created by default.
  2. Under Project|References, add a reference to the Microsoft ActiveX Data Objects 2.1 Library and then click OK.
  3. Press the CTRL+T keys to display the Add Components dialog box. Add the Microsoft Office Web Components, and then click OK.

    NOTE: Office XP includes both Office 2000 and Office XP Web Components. To use the Office 2003 Web Components, add the Microsoft Office Web Components 11.0 library. To use the Office 2000 Web Components, add the Microsoft Office Web Components 9.0 library. To use the Office XP Web Components, add the Microsoft Office Web Components 10.0 library.
  4. Add a PivotTable to the form.
  5. In the code window for Form1, insert the following code:
    Option Explicit
    
    Dim cnnConnection As Object
    
    Private Sub Form_Load()
    
       Dim strProvider As String
       Dim view As PivotView
       Dim fsets As PivotFieldSets
       Dim c As Object
       Dim newtotal As PivotTotal
       
       strProvider = "Microsoft.Jet.OLEDB.4.0"
       ' Create an ADO object
       Set cnnConnection = CreateObject("ADODB.Connection")
       ' Set the provider and open the connection to the database
       cnnConnection.Provider = strProvider
       cnnConnection.Open "C:\pivottest.mdb"
       ' Set the pivot table's connection string to the cnnConnection's connection string
       PivotTable1.ConnectionString = cnnConnection.ConnectionString
       ' SQL statement to get everything from table1
       PivotTable1.CommandText = "Select * from table1"
       
       ' Get variables from the pivot table
       Set view = PivotTable1.ActiveView
       Set fsets = PivotTable1.ActiveView.FieldSets
       Set c = PivotTable1.Constants
       
       ' Add Category to the Row axis and Item to the Column axis
       view.RowAxis.InsertFieldSet fsets("Category")
       view.ColumnAxis.InsertFieldSet fsets("Item")
       
       ' Add a new total - Sum of Price
       Set newtotal = view.AddTotal("Sum of Price", view.FieldSets("Price").Fields(0), c.plFunctionSum)
       view.DataAxis.InsertTotal newtotal
       view.DataAxis.InsertFieldSet view.FieldSets("Price")
          
       ' Set some visual properties
       PivotTable1.DisplayExpandIndicator = False
       PivotTable1.DisplayFieldList = False
       PivotTable1.AllowDetails = False
    End Sub
    
    Private Sub Form_Terminate()
      ' Remove reference to the ADO object
      Set cnnConnection = Nothing
    End Sub
    
    
    Private Sub PivotTable1_DblClick()
       Dim sel As Object
       Dim pivotagg As PivotAggregate
       Dim sTotal As String
       Dim sColName As String
       Dim sRowName As String
    
       Dim sMsg As String
       
       ' Get the selection object you double-clicked on
       Set sel = PivotTable1.Selection
       ' If it is a aggregate, you can find information about it
       If TypeName(sel) = "PivotAggregates" Then
          ' Select the first item
    
          Set pivotagg = sel.Item(0)
          ' Display the value
          MsgBox "The cell you double-clicked has a value of '" & pivotagg.Value & "'.", vbInformation, "Value of Cell"
          
          ' Get variables from the cell
          sTotal = pivotagg.Total.Caption
          sColName = pivotagg.Cell.ColumnMember.Caption
          sRowName = pivotagg.Cell.RowMember.Caption
          
          ' Display the row and column name
          sMsg = "The value is " & sTotal & " by " & sRowName & " by " & sColName
          MsgBox sMsg, vbInformation, "Value Info"
       End If
    End Sub
    					
  6. Next, create a sample database using Microsoft Access. Start Access and choose Blank Access Database. Save the file as c:\pivottest.mdb. Double-click Create Table in Design View. Enter the following data:

    Collapse this tableExpand this table
    Field NameData Type
    ItemText
    CategoryText
    PriceNumber
  7. Close the Window and save changes as Table1. Select No for creating a key. Double-click Table1 and enter the following data:

    Collapse this tableExpand this table
    ItemCategoryPrice
    NailsHardware5
    ShirtClothing23
    HammerHardware16
    SandwichFood5
    PantsClothing31
    DrinksFood2
  8. Close Access to save the file.
  9. Press the F5 key to run the project. After running, the pivot table should populate. Double-clicking on a cell with data shows the value of the cell and the cell column and row names.
