SYMPTOMS

In the versions of Microsoft Excel listed above, if you run a Visual Basic for Applications macro that sets the Type property of a trendline in a chart, you may receive the following error message:

This program has performed an illegal operation and will be shut down. If the problem persists, contact the program vendor.

If you click Details, you receive an error message similar to either of the following:

EXCEL caused an invalid page fault in module EXCEL.EXE at 0137:30365bcf.

-or-


EXCEL caused a general protection fault in module EXCEL.EXE at 00eb:00004464.

CAUSE

This problem occurs when the Name property of the trendline is empty (""). For example, the following line of code makes the Name property of a trendline empty:

   ActiveChart.SeriesCollection(1).Trendlines(1).Name = ""
                

WORKAROUND

To work around this problem, make sure that each trendline in the chart has a non-empty Name property before you attempt to change its Type property.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
