If the problem can be stated more clearly, my guess is that it's a variant of the bin packing problem[^]. The article mentions that this problem is NP-hard, which effectively means that the time required to find the optimal solution rises exponentially, although it may be possible to more efficiently find a solution that is known to bounded in terms of how close it is to the optimal one.

Yeah, you're right. I'm sort of guessing here; I misunderstood your original question. How about the SelectedGridItem property? CQ de W5ALT Walt Fair, Jr., P. E. Comport Computing Specializing in Technical Engineering Software

keefb is 100% correct. If you type "0.3 / 0.1" into the immediate window, it spits out 2.9999999999999996... Now, we all know that's pretty much "3", but if you do a Floor(), it rounds down to 2. As keefb said, use decimals and you'll get the right answer. But if you need to work with doubles, or have other constraints, you could "hack" it by, say, adding 0.0000001 before going through the Floor()... Kind of like the stone-age trick of adding 0.5 before a truncation to simulate rounding up or down to an integer. Proud to have finally moved to the A-Ark. Which one are you in?

Completely true and yet a big mouthful... Don't forget to vote if the response was helpful Sig history "dad" Ishmail-Samuel Mustafa Unix is a Four Letter Word, and Vi is a Two Letter Abbreviation

Nope the icon file contains only one image.

I figured it out. I was being a dummy. My type converter class(es) where of base type ExpandableObjectConverter when they should have been TypeConverter.

I learned banker's rounding in High school, so it just seems natural to me. Check out this[^]. Take care, Tom ----------------------------------------------- Check out my blog at http://tjoe.wordpress.com

Yes but then the focus will not get set to the text box, if the user uses Control-Tab to scroll through the tab pages.

How do you hide it? I have a situation where I want a fairly simple PropertyGrid, but I do not want the help panel to display. Thanks, John

Hi, So for every property change, the code executes, creates a new Regex and makes it Replace something. Regex is an expensive class by itself, it has to either interpret your intentions, or, optionally generate compiled code for it (more cost effective only when required over and over, not your case). If the user types 5 characters for a property, it changes five times. I would look for a way to run the code less frequently. Some ideas: - let the user trigger the code by clicking a button or so (less comfortable); - let a timer trigger the code; maybe have a scheme where the worker runs say 3 seconds after the last change (i.e. every change starts/restarts a timer, and only when the 3 seconds elapse is the code executed). Hope this helps :) Luc Pattyn try { [Search CP Articles] [Search CP Forums] [Forum Guidelines] [My Articles] } catch { [Google] }

So they're coders rather than software engineers. It's an uphill struggle. The tigress is here :-D
