• Microsoft Access version 2.0, 7.0, 97

SUMMARY

Moderate: Requires basic macro, coding, and interoperability skills.

This article describes how to use the Circle method to create a filled-in "pie slice" on a report.

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.

NOTE: Visual Basic for Applications is called Access Basic in Microsoft Access version 2.0. For more information about Access Basic, please refer to the "Building Applications" manual.

MORE INFORMATION

The following sample user-defined function, PIE(), can be called from an event property on the report's detail section. The function uses the Circle method to create a filled-in "pie slice" on the report:

1. Start Microsoft Access and open any database.

2. Create a new module and enter the following code:

         Function PIE(Rpt as Report)
            Const PI = 3.14159265359
            Const CStart = -.00000001
            Const CEnd = -2 * PI / 6
   
            Rpt.FillColor = RGB(255, 0, 0)
            Rpt.FillStyle = 0
            Rpt.Circle (1500, 1500), 1500, RGB(0, 255, 0), Cstart, CEnd
         End Function
   
   

3. Create a new report named TestReport. The report can be bound or unbound.

4. Set the OnPrint property of the report's detail section to the following expression:

         =PIE([Reports]![TestReport])
   

5. Set the Height property for the detail section to 2.5 inches.

6. Preview the report.
