Re: alwaysBuffer vs. screenNoPixMaps

Setting a character with imagesource through htmlText?
If you set the text of a field to test and then set the imagesource of char 3 of that field to 20, you'll see te followed by a beachball followed by t If you put that field, you'll get test If you put the htmlText of the field, you'll get: pteimg src=20t/p Note the absence of the character s If you set the htmlText of the field to the htmlText of the field, there will be no visible change. But if you put the field, you'll now get te t with a space where the s used to be. Question 1: is this a bug? I think so. I don't see this in bugzilla, so if consensus is that this is a bug I'll enter it. Question 2: any ideas for a workaround? Setting the htmlText of a field is dramatically faster than putting text into it and then setting the imageSource of each character individually, but it can be very handy to have a character hidden within an image, since it can be a quick reference to what the image is. regards, Geoff Canyon [EMAIL PROTECTED] ___ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution

Jerry Daniels has found that setting imageSource via script (in reality, setting the HTMLtext of the field) is much faster than setting the imageSource character by character. So perhaps this could be your workaround, and a faster workaround at that. It's just a little more coding to accommodate the HTML tags.

In the above function I have chosen to slightly alter the given points so that the lines intersect at a great distance (close to infinity, so to speak.) The above intersection function assumes that these are effectively the infinite lines of Euclidean geometry. The end points are simply two points which define the infinite lines. To find out whether the intersection point lies between the end points of each line you will need to test whether the distance between the intersection point and ALL the end points is less than the length of each line respectively. (I can't imagine that sentence is clear.)

Re : scale w/ ticks and snap-to
Hi Richard, Paul and Ken, I would add some points to your today enjoyment about scrollbars ;-) 1. It is a Mac OS issue since there are no ticks on Windows scrollbars... (I love ergonomics!) 2. You are right, the workaround does work from 4 to 15, but not for 2, 3 or more than 15! 3. In the scrollbarDrag handler, I prefer set the thumbPos of me to round(the thumbPos of me) to set the thumbPos of me to the thumbPos of me: Using round function allows the cursor to follow exactly the mouse movement and snap gently at mouseUp Without round function, the cursor snaps when the mouse is down (it always wins this terrific struggle...) and I don't like interface elements that don't obey to the user (i.e. me :-) That's with OS X, I don't test it with Win32.

custom property searching speed question
Say you had a custom property set - theProps And the keys of this set were 1 through 500,000 So, basically, you had an array with half a million elements stored as a custom property set. Then, you wanted to search that array, and do it in such a way that the search returned the name and content of the first custom property that contains the item for which you search. Would the following method be fastest? Set the custompropertyset to theProps Put 0 into Z Repeat for each element E in the customproperties of myobject Add 1 to Z If E contains searchterm then exit repeat End repeat Put Z the customproperties[Z] of myobject into field feedback My questions are this: 1) Is there a better or faster-access way to store the array than as a custom property set? 2) Is there a search method that is faster than doing all those comparisons in transcript? For example, lineoffset and itemoffset are supposed to be very fast. Is it possible to use itemoffset on an array, or is there anything that works like an elementoffset command would work, if it existed? 3) Would it be faster to combine the array, and use itemoffset? 4) Could filter be made to work in this situation, or would it only give the value of the element, but not the name of the element? 5) Anything faster that I am not thinking of?

Using repeat for each line on a string benchmarked about 20% faster here than using repeat for each element on an array. I only tested on 40,000 lines, though. In general repeat for each... scales well, so I would feel fairly confident extrapolating my results to larger data sets. 2) Is there a search method that is faster than doing all those comparisons in transcript? For example, lineoffset and itemoffset are supposed to be very fast. Is it possible to use itemoffset on an array, or is there anything that works like an elementoffset command would work, if it existed? 3) Would it be faster to combine the array, and use itemoffset? Offset can rip through large blocks of text very fast, but it's not very precise. For example, in my case I had to do comparisons on specific items within a line. LineOffset will get you to that line, but won't tell you where within that line it is. With a low number of hits lineOffset can be faster to find the line, and then you could evaluate specific elements to find the item if needed. But for larger numbers of hits it should be slower, since once you find the line you still need to get line x, and that requires the engine to count lines. Requiring the engine to count lines is the bottleneck. So for my purposes, using repeat for each line gave me a consistently scalable solution which allowed me to query any items within a line without ever having to count lines. So lazy person that I am, I stopped there and moved on to other things. :) 4) Could filter be made to work in this situation, or would it only give the value of the element, but not the name of the element? Filter may benchmark the fastest if you're looking for an item anywhere in a line (never tried it myself, since I need to find matches for specific items within lines, but worth testing). 5) Anything faster that I am not thinking of? Probably. Search algorithms are a deep subject, and there's always one more clever way to solve a given problem. I stopped benchmarking these things once I found that repeat for each line was coming out okay. Because I have so many comparisons to perform on specific items within a line, it gave me a robust (though admittedly brute force) solutuion with acceptable performance on data sets larger than will be needed in real-world performance with my app's audience. But with half a million records it begs the question: Why not consider a database, where searching is done by compiled code optimized by people who specialize in such things? -- Richard Gaskin Fourth World Media Corporation __ Rev tools and more: http://www.fourthworld.com/rev ___ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution

Locking the screen for a moment seems to help, but as soon I switch out of rev and then back, the icon images appear jagged again. Anyone else encounter any problems with images in drawer stacks?

cgi scripting for Miva
I haven't done any cgi scripting with Rev, but I'm needing to put together something for a Miva Merchant store that I'm just setting up. Here's the scenario: A customers orders products from our Miva store, I get the order as a simple email. I then forward it along with the attachment of a .pdf file of the product and a .pdf mailing label to a fulfillment center that prints the product and the label on demand and sends the order on to the customer. There will be hundreds of different .pdf files, with new ones being added from time to time. Storing my .pdfs at the fulfillment center is not an option. There are modules that you can add to Miva that will send emails with attachments to the customer, but none that I'm aware of that will send attachments to a vendor. I did find a module that will send XML data to a vendor, but not an attachment without the help of something else. Being a Revolution hobbyist I thought maybe there was a solution there. Any comments? Am I in over my head? Marty Knapp ___ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution

RE: custom property searching speed question
Does filter work on an array? Anyway, I experimented with a customproperty set created to contain 500,000 elements - each element contains like 7 words. Only the very last element contains the word nonstandard So far, the following script is fastest: on mouseUp put the milliseconds into M put field search text into ST put the customproperties of field theData into myArray repeat for each element E in myArray if matchchunk(E,ST) = true then put E into field output exit repeat end if end repeat put the milliseconds into M2 put (M2 - M)/1000 into field feedback end mouseUp Each element was created so that the name of that element is the first word of the element - meaning I do not have to keep track of which element we are dealing with - as long as I have the value of the element, I automatically have the name of the element as well. If the word being searched for is in the 500,000th element of the custom property set, then it takes 1.059 seconds to find (with like 4 other programs running on my computer at the same time) If the elements are already combined into a single variable, then lineoffset takes just as long! I guess repeat for each is exceedingly fast. If I could figure out how to use filter on an array - and how to get it to work in the same way as using contains then I would test it with the filter command - but so far this eludes me. In my experiements with this, it seems that an if-then structure was faster than a switch structure - is this always true? ___ use-revolution mailing list use-revolution@lists.runrev.com http://lists.runrev.com/mailman/listinfo/use-revolution

Tell me about PGM - preferably off-list, since this is starting to get very OT, but I'm posting the request here in case there's other interest. Rev does support sending either broadcast or multicast - I can send UDP packets to 192.168.0.255 and also to 224.0.0.251 and receive them on my (on-Rev) echo server. But it doesn't support receiving them - there's no access to raw sockets or to setsocketopt(). Thus, there is no way to let the system know which multicast groups are to be received (necessary both to get the system to send / respond to IGMP packets as well as to set the correct bits in the Ethernet driver to receive the packets).

My line of thought here is which distro is best and if a graphic engine is needed, xwindows, kde or.. Any suggestions would be much appreciated.

Re: Mortgage calc.
OK, Hershel. Here's the example. You can tweak it to suit your purposes. And my sincere apologies to everyone on the list for duplicating this lengthy message. I had forgotten to enter a specific Subject in the first one In Canada, ING Direct offers a three-year fixed term, twenty-five year mortgage for a posted rate of 4.45%. They don't offer a thirty-year amortization; that's why I chose twenty-five. For a $300,000 loan, you would be paying $1,652.09 per month. My answer is correct to the penny. Here's how to set up the problem. Each variable is indicated in parentheses. Posted annual rate (r1): .0445 Payment frequency (m): 12 (i.e., monthly) Effective monthly rate (r2): 0.00367441421 (you'll figure it) Amortization (N): 25 years Principal (P): $300,000 Payment (A): $1,652.09 (you'll figure it) Annuity factor (F): 181.58815514 (you'll figure it) Step 1 You need to convert the posted rate (r1) to the effective monthly rate (r2) because the posted rate is always a year but the effective rate corresponds to the frequency of your payments (monthly, semi-monthly, bi-weekly, weekly, etc.). Notice that r2 is not simply r1 divided by 12 (or m). That's because of compounding. So you have to find r2 by answering this question: what rate, r2, which when compounded for 12 periods gives us r1? The added twist in Canada is that, by convention, compounded is taken to occur semi-annually, so .0445 actually slightly understates the true posted rate. I'm not sure if that's done in the US. Confused yet? Look at the numbers. (The carets, ^, mean take to the power of...). (1 + r2)^12 = (1 + r1/2)^2 Rearrange to solve for r2 in general to get r2 = (1 + r1/2)^(2/m) - 1, where (2/m) means take the mth root and square it. Plug in the numbers to get (1 + .0445/2)^(1/6) - 1 = 0.00367441421 So, that's your effective monthly rate. Change m to 4 and it becomes an effective quarterly rate; 52 and it's a weekly rate, and so on. You may want to write a function for it. Step 2 Now you can use the effective rate in the standard annuity formula to get the annuity factor, F, that you'd use to divide any principal amount in order to compute the payment, A. F = (1 - (1 + r2)^(-N*m))/r2 Plug in the numbers. Note N*m = 25 years x 12 months = 300 (easy) payments (ouch). F = (1 - (1 + 0.00367441421)^(-300))/0.00367441421 F = 181.58815514 Create the function, F, which is itself a function of r2, N, and m. Step 3 To get the monthly payment, just divide the principal by F. A = P/F(another function you can create) Plug in the numbers. A = $300,000/181.58815514 = $1,652.09 Or you can do create tables of A for a mortgage book like the banks used to use by computing A per $1,000 borrowed as a function of different rates, amortization periods, and frequency of payment. In this example, A = $5.5069671214 per $1,000 borrowed. Of course, you can collapse Steps 1 and 2 into 3 to create a function that computes the payment directly.
