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"

Back to the top

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.
