Q163799: PRB: Olegraph.scx Sample Fails if Graph 8 Is Installed

Article: Q163799
Product(s): Microsoft FoxPro
Version(s): 5.00 5.00a
Operating System(s): 
Keyword(s): kbsetup
Last Modified: 26-AUG-1999

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

If you run the Visual FoxPro Olegraph.scx sample (samples\solution\ole) after
installing one of the Office 97 products, you receive the following error:

  "OLE error code 0x8002005 type mismatch"

CAUSE
=====

This error occurs because Visual FoxPro includes Microsoft Graph Version 5 with
the product but Office 97 ships with Microsoft Graph Version 8.

The Olegraph.scx sample in Visual FoxPro uses a graph function called AutoFormat.
Graph 8 has no such function. Graph 8 uses a property called ChartType for
setting or reading the type of graph you are using.

RESOLUTION
==========

To set the type of graph in Graph 8, use the ChartType property. To fix the
sample so it will run with Graph 8, you need to perform the following steps:

1. Modify the Olegraph.scx form (located under samples\solution\ole).

2. In the init of the form, change the line that reads:

        THIS.OleBoundControl1.autoformat(11,1)

  -to-

        THIS.OleBoundControl1.ChartType = 60

3. In the Optiongroup1 Click event, change the 3 lines that read:

        THISFORM.OleBoundControl1.autoformat(11,1)
        THISFORM.OleBoundControl1.autoformat(12,1)
        THISFORM.OleBoundControl1.autoformat(14,7)

  -to-

        THISFORM.OleBoundControl1.ChartType = 60
        THISFORM.OleBoundControl1.ChartType = 54
        THISFORM.OleBoundControl1.ChartType = -4102

4. Save the form as Olegraph8.scx and then run it.

STATUS
======

This behavior is by design.
