The file to download is xsdref.msi. You can google for it. I believe I got it at:

The way I went about implementing changes was:
1) Investigate if decision can be made from data in frx (for this you can help yourself with 90frx.frx report that is in HOME()+'Tools\Filespec')
2) Learn how to tell Excel. One way was with help file found at address above an another was to save file with Excel before and after a single change and compare files.
3) When it became necessary to add a command in comment I tried to make the command generic and simple to use.

In the case you mention that background color should not be set if VFP report has transparent background (seems like a reasonable assumption) the first step would be to investigate how VFP saves transparent background.

Even though I added characteristics as you seem to be doing, driven by need, it is important to keep the future in mind and try to be as generic and coherent as possible.

I think if several of us work on this class we can make it very useful. It would pay to coordinate efforts so we can have a richer and richer single class that handles many different situations easily.
