RE: Re: [DUG]: Dumb question of the day
Hi Rohit, Apologies if I sounded abrupt: I was trying to not be personal - but to point out that adequacy for any individual's needs is not a test of the VCL's competence. The point I was making, yes I'm feeling more tolerant today, is that "childish" is not a good description for the VCL. Inadequate for your purpose, frustrating etc - I can't disagree with that, nor argue with your, or anyone else's, competence. The point I was making was that the VCL does what it was intended to do, which is clearly less than some people want (which is why Max et al have had to "fix" it) - but still what was intended and, arguably, what the majority of Delphi users need. That may make it a commercial solution, rather than a technically pure one - but not a childish one. Nor was I questioning your competence - the fact that you, and your clients, set a high standard is not in question. But neither does that mean that the VCL is childish, and hence inadequate for the vast majority of us mere mortals. I understood that what you were saying was something like "I get frustrated when the VCL doesn't do what I want" - but I reacted to the emotionally charged connotation behind "childish". No offence intended.

RE: Re: [DUG]: Dumb question of the day
I guess I should take up the challenge... (OK I'm feeling combative today) Does that imply that those of us who can produce complex applications, that involve significant data validation and implement complex business rules, using "original Borland components" are "childishly deficient" as well? I've found that, in the very rare cases where data-aware components can't be used and the likes of the string grid's "OnSetEditText" can't be used, straight-forward extensions to the original components are entirely satisfactory. After-all, in the best-of-all-possible-worlds data-types will do all data validation. OK sometimes you have to use creative SQL statements (I've currently got a bunch of UNION'd SELECT statements to get the data in the form I want for a TDBChart - yes performance is OK) but that's part of the creativity required for any good problem-solving. I'm not saying you should develop the way I do; just that it _IS_ possible to get sophisticated data-validation with the included stuff. If you don't like them because of style - that's OK too but be aware that that's your style of development and nothing to do with the VCL or it's capabilities. Or to put it another way: the engineers who created Delphi and the VCL have a great deal more technical depth that most of us. Attending Icon (was BorCon) and listening to their answers to some of the more searching questions is evidence enough of that. So I think you'll find that the VCL has been crafted the way it is on purpose, not by accidental omission. The more I understand the VCL, and therefore the more I feel competent to pass judgement, the less likely I am to characterise it as "Childish".

But most grids have a on the fly created editbox called InPlaceEditor. I tried it with stringgrid but it doesnt work. It works in other grids though. You might have to examine the VCL source.
