I’ve had this error pop up while trying to open Excel files (Excel 2007) after installing Live Office on several machines where it says “There was a problem sending the command to the program“. A couple other people ran into the same issue, so I’d like to post a quick solution.

1. Open the Excel program
2. Go to Excel Options
3. Go to Advanced
4. Go to General
5. Make sure “Ignore other applications that use Dynamic Data Exchange (DDE)” is unchecked.

That’s all!

This article talks about using the filtered rows technique instead of a VLOOKUP.
Not until Xcelsius 2008 came out, were we able to filter on multiple rows of data that matched 1 entry. So in order to accomplish this we would either have to use VLOOKUP or INDEX MATCH. Using this technique was very cumbersome and although filtered rows has been available for a while, I have been on a couple engagements where I still see VLOOKUPS in the excel spreadsheet!

Thus hopefully writing this article will get the practice of using filtered rows ingrained in the
Xcelsius Developers minds.

I’ve created a video below that shows 2 scenarios below using VLOOKUP and filtered rows. I’ve shown how much easier it is to use filtered rows and how much easier it is in the future to maintain.

I’ve also attached the source files from the 2 examples so you may do your own comparisons.
