Depends what you're trying to do. For a start, the number must be in a string. Secondly, the way you've presented your example suggests to me that you have an array. Since RegExp wants text input, you'd have to Join() your array. And that will probably be leading you away from anywhere that I...

What I want to know is speed performance an unfortunate overhead of Com+ or is it simply bad programming. I have had a peek at the code and fear it is the latter There is an order-of-magnitude response time drop when moving from a class in process to one that's out of process and another when...

Well, having had time to read it, I found it interesting. The approach seems to be generally sound; my main suggestion would be to consider improving cohesion by extracting the database functions from the collection ones. Much as in the Engine-Collection-Class pattern described on MSDN, which...

So you'd have a class that delivered, say RunnersFor(Race) and Racesfor(Runner) methods?

In data modelling terms, Performance would be an entity that represents the linkage between runners and races (a 'many-to-many' relationship). Once implemented as a table, this gives you a single source for "all races for a runner" and "all runners for a race". Taking a...

Gosh, that was a little terse! In case you're not familiar with the reference, GoF refers to "Design Patterns" (written by the "Gang Of Four") ISBN 0201633612, which is the pattern bible. Also see http://c2.com/cgi/wiki?CommandPattern Another possibility might be...

Command? (GoF p 233]?

I don't know if there's a 'clever' algorithm for this, but I'd proceed something like this: 1. Either sort your arrays in the sequence of the join condition (one or more fields) or if the records in the arrays are large or there's a lot of 'em, create new key-reference arrays and sort those...

Of your two options, the second (single class) seems clearly preferable to me. I'd say you were talking about the Facade pattern (http://c2.com/cgi/wiki?FacadePattern). At least you get the benefit of an interface being present, behind which the external functions can be hidden. You might also...

Since you're asking your question in OO terms, I'd repsond by asking if you've considered why your form needs to know anything about the database? Part of the principal of encapsulation is ensuring that responsibilities are divided among classes such that each does one job well. I'd say you were...

From (often faulty) memory: you need to use an ImageList control to store the icons and link it to your ListView at design time. It gets annoying when you add images to the ImageList, because you have to decouple the ListView to do it, then relink and reassign the icons. So make sure you've got...

I suspect that you're not going to be able to do what you describe - the "Application" object for VB is "App", but of course it's the program itself, whereas in Access it's Access. Why does your form need a reference to its caller? What assumptions will your DLL have to make...

Note that if you're not working in mm/dd/yyyy format (i.e. if you don't work in North America), you'll need to put your date string into it before it will work. Mike
