>>>Mike, I appreciate your points but reserve right to stay on my owns. The major concern here is that 'in the long run' statement looks really suspicious these times. I mean that having new version patch every 6 month, new version every year, and new language every few years, it's painfully difficult to make long-run stakes.

>>Ed,
>>I agree with you. For the most applications I do, frameworks are a nuisance. And what I have seen of the commercial ones they have so much over head checking 100 things for every conceivable circumstance that their proformance suffers greatly. If I want something to run slow I can use Access or Oracle. I use Foxpro for the speed an flexibility.

>VFP is not our father's xBase. VFP is a fully object oreinted development environment and as such there is a lot of object management that is required behind the scenes. The job of a framework is to manage those things. To manage interobject communications, forms, menus, toolbars, etc. In order to do this they usually give us classes we can use to build those things.

>Arguing that a framework requires overhead is like saying that if I write a line of code it has to be executed. If I write an aplpication that does not handle the interobject communications, or that severely limtis the possiblities of that communication, then I get what what I wrote, a severely limited application.

>I had the luxury of having been hired by a consulting firm to write a framework for them, so I got padi for it. Most developers will not get paid for writing a framework, that effort will be unbillable time spent. Yes it pays back over time,but so does the cost and time involved in buying and lerning a commercial framework (and that is invariably less time and money than building your own).

I agree with you and I believe you saw that my reply didn't argue framework validity. I also have luxury to create and use my own frame methodology and I like this. Again, I agree and use classes, unlimitedly modeless interface and so on.
