Duplicating XML tree
Hi, I have an XML tree in memory, loaded with revXMLCreateTreeFromFile. Now I want to make a copy of the tree. I could load it from file again, but it seems more logical to me to duplicate the existing tree, something like revXMLCopyTree, but that function doesn't seem to exist. Is there a command or function for this purpose that I haven't discovered yet? -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering Homepage: http://economy-x-talk.com Twitter: http://twitter.com/xtalkprogrammer KvK: 50277553 Installer Maker for LiveCode: http://qery.us/468 Buy my new book Programming LiveCode for the Real Beginner http://qery.us/3fi LiveCode on Facebook: https://www.facebook.com/groups/runrev/ ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Re: Duplicating XML tree
Hi Martin, I was hoping to copy the tree directly. I thought of your solution and I could also load the tree from file twice in this particular case, but I'd rather copy an existing tree directly if possible. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering Homepage: http://economy-x-talk.com Twitter: http://twitter.com/xtalkprogrammer KvK: 50277553 Installer Maker for LiveCode: http://qery.us/468 Buy my new book Programming LiveCode for the Real Beginner http://qery.us/3fi LiveCode on Facebook: https://www.facebook.com/groups/runrev/ On 6/16/2014 16:07, Martin Koob wrote: I think you can do it this way. put revXMLtext(tTreeID) into tXMLdata put revXMLCreateTree(tXMLdata,false,true,false) into tTreeIDCopy Martin ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
numberFormat question
I am trying to set the numberFormat so that calculation is precise enough for the situation. Since I don't know ahead of time how many decimal places will be used, I wrote a function that I hoped would adjust things as necessary. But when this function is called with parameters m = 1.09131 and n = .001 and k = 1, it returns 1.09131 rather than 1.0913101. The last couple of lines were added for testing, and the debugger shows that the numberFormat is being set correctly but that the truncated value is put into hold. Can anybody see what is going wrong? Many thanks. David Epstein function preciseEnough m,n,k -- return the value m + k*n -- default numberFormat shows up to 6 decimal places -- If m, n, or k has more than that precision, this function sets the numberFormat with a margin of safety -- before returning the answer put length(m) - offset(.,m) into aPlaces put length(n) - offset(.,n) into bPlaces put length(k) - offset(.,k) into cPlaces put the numberFormat into myString if max(aPlaces,bPlaces,cPlaces) + 4 length(myString) then get myString set the numberFormat to it end if put the numberFormat into nf put m + k*n into hold return hold end preciseEnough ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Diagnosing server error 400
I need help figuring out why AWS is returning an error 400 bad request in a limited number of cases. We have a test group of some dozens of people and only 2 have the problem. What I know: The data sent to the server is the same for everyone, and is correctly formatted. I have logs of that and the requests are okay. One person moved to another computer (and consequently another network) and the problem resolved itself. Once, my client was getting the same 400 error all morning and then that afternoon it started working again by itself, without changing anything. This definitely seems network-related to me but I don't know what it could be. The queries are reaching AWS and it is returning the error. We don't have access (or don't know how) to see the server logs that Amazon has; we only have access to the logs on our own server, and the requests never get that far.

Re: numberFormat question
David, The numberformat doesn't affect precision. It only affects output as is shown by on mouseUp set the numberformat to 00 put 0.01*1 into x set the numberformat to 00.00 put x*1 end mouseUp It even only affects the current handler and doesn't affect precision in calling handlers: on mouseUp // default is 0.## put a1() into x put x*1 end mouseUp function a1 set the numberformat to 00 return 0.01*1 end a1 The above script returns 0.01 instead of 00. I don't think LiveCode allows you to adjust the precision as other languages to with e.g. signed and unsigned integers and floating precision. You'd have to write special routines for this. I think there is quite a lot of discussion to find in the archives about high precision and floating point numbers. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering Homepage: http://economy-x-talk.com Twitter: http://twitter.com/xtalkprogrammer KvK: 50277553 Installer Maker for LiveCode: http://qery.us/468 Buy my new book Programming LiveCode for the Real Beginner http://qery.us/3fi LiveCode on Facebook: https://www.facebook.com/groups/runrev/ On 6/16/2014 20:13, dfepst...@comcast.net wrote: I am trying to set the numberFormat so that calculation is precise enough for the situation.

When you use #, it means to include a numerical value in that postion only if there is an actual value there; if there is no value then that position is ignored. If you use 0 in the numberformat instead, empty positions are padded with zeros. So, to get the precision you want, you don't need to calculate the number of places/positions, just use the # as you are now. Include enough #s to cover your longest anticipated number, up to LC limits (I think that's 16 places.) Since numberformat only affects the display, you need to force the calculation from a numerical value to a text value. You can do that by simply putting the result of the calculation into a field. If you want it in a variable, you can use value() to do that instead. So your whole handler can be like this: function preciseEnough m,n,k put m + k*n into hold set the numberformat to 0.## -- add more if you want put value(hold) into hold return hold end preciseEnough -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: numberFormat question
Also, if you don’t care about display, just set the *precision* to LC max. Numberformat is as others have posted, really a display function. After you are done, set the numberFormat back to default or “0”. I bit myself in the butt because I had a counter that I was using to append a number to a variable name, and it hosed my names.

Landman Gay jac...@hyperactivesw.com wrote: set the numberformat to 0.## -- add more if you want I think the reason David isn't doing that, and is trying to limit the number of # to the absolute minimum is because of this note in the Dictionary: Note: Since LiveCode does not use decimal numbers for its internal calculations (for reasons of speed), the decimal representation of a number is sometimes slightly off the correct number. For example, 10^-1 is equal to 0.1, but is calculated (to eighteen decimal places) as 0.16. Because of this, setting the numberFormat to specify many decimal places after the decimal point may produce unexpected results in a statement that tests for an exact number. To prevent this, either avoid setting the numberFormat to a value more precise than you need, or use the abs function instead of the = operator to test equality: I think we all know that at least once or twice a year we get a post to this List questioning why LC is getting it's math wrong and the reason is as stated above. For anyone whose app requires precision math that shouldn't be a note, it should be a CAUTION! It's so easy to have your app work perfectly 99.% of the time... but then ruin someone's day. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

I'm in the dark about what's going on over at the server side, but on my end, I'm just doing a GET to a URL.

The server person said my requests are hitting the SQS queue, which isn't related to Cloudfront. She knows about Cloudtrail logs but suspects that the hit isn't even making it to SQS to get logged. This is sort of gibberish to me, but it means something. Maybe a better question to everyone would be: can a server 400 error be related to a bad SSL certificate chain? Because that's the only thing I can think of. Are these security chains static or do they vary depending on the computer/network involved? That is, is it like a URL request that can take any path to the destination, or more like a specific, unchanging set of security checkpoints? Amazon talks about a PEM file that lists the security checkpoints, so I suspect the latter.
