Subject Re: [IBO] Migrating BDE/MIDAS applicaiton to IBObjects and MIDAS
Author Ed Malloy

I can only report my own experience.

IBX conversion was a no-brainer. Absolutely no conversion problems; The TIBDataSet works exactly as I would like. Our
applications are not extremely complex, about 30 basic tables plus anilliary tables. They do order-entry/fulfillment and the
management. I could never quite get IBO to work the way I wanted it to work.

I was never interested in replacing my infopower grids nor my orpheus data edits, so that part of IBO never interested my (and
it is my opinion that you have spread yourself WAY to thin in the developmnet of these controls).

Finally, the IBX documentation answered my questions; where the IBO documentation usually left more questions to be answered.

For me the bottom line is that IBO did not do what IBX does. As you know I purchased IBO licenses and gave them a fair test. For
our uses, IBX fits, and I chose not to try and fit our applications to IBO's demands.

Tank care,
