Embedded Excel in browser doesn't indicate if chart is in focus!

[Neo]

Hi All,

Our application opens Excel sheet in a browser. We want to put a
validation that chart object shouldn't be in focus while saving this
workbook. In this case chart.isActive returns false even when there is
a chart and is in focus! we are using C++ instead of vba in this case.
The versions are IE 6.0.2 and Microsoft Excel 2000.

Any help is most welcome!

Regards,
Rohit
