Follow the steps below to create a Visual Basic, Applications Edition, procedure and then run it from Visual Basic 3.0.

1. Type the following code into a new Microsoft Excel module sheet in a new workbook.

' This procedure creates a new workbook, enters some numbers in a
' worksheet, creates a chart, rotates the chart, and then closes
' Microsoft Excel.
 
            Sub SpinIt()

      Dim ExcelChart As Object
      Dim i As Integer

         'Create a new workbook, type in three numbers, create a chart,
         'and change the chart type to 3-D Column

         Workbooks.Add
            Range("a1").Value = 3
            Range("a2").Value = 2
            Range("a3").Value = 1
            Range("a1:a3").Select
         Set ExcelChart = Charts.Add()
         ExcelChart.Type = xl3DColumn

         'Rotate chart
         For i = 30 To 180 Step 10
            ExcelChart.Rotation = i
         Next

         'Close all open files and quit Microsoft Excel.
         Application.DisplayAlerts = False
         ActiveWorkbook.Close (False)
         Application.Quit

       End Sub
				

1. Save the workbook as VB3OLE.XLS in your root directory.
2. Start Visual Basic 3.0, and on a new form, create a button.
3. Double click the button and type the following code into the procedure window:

         Sub Command2_Click ()
             Dim ExcelApp As Object
             'Opens Excel OLE Object
             Set ExcelApp = CreateObject("excel.application")
             ExcelApp.Visible = True
             'Opens the previously saved Excel workbook and runs the macro
             ExcelApp.Workbooks.Open ("c:\vb3ole.xls")
             ExcelApp.run ("spinit")
             Set ExcelApp = Nothing
             End
         End Sub
   						

4. Close the procedure window, and choose Start from the Run menu.
