  • Using a variable as identifier in a json array

    - by Robbert van den Bogerd
    Hi folks! I'm wondering if it is possible to use assigned variables as identifier in a json array. When I tried this, I was getting some unexpected results: (Code is simplified, parameters are passed in a different way) var parameter = 'animal'; var value = 'pony'; Util.urlAppendParameters (url, {parameter : value}); Util.urlAppendParameters = function(url, parameters) { for (var x in parameters) { alert(x); } } Now the alert popup says: 'parameter' instead of 'animal'. I know I could use a different method (creating an array and assigning every parameter on a new line), but I want to keep my code compact. So my question is: Is it possible to use a variable as an identifier in the json array, and if so, could you please tell me how? Thanks in advance!

  • Find top "n" nearby coordinates.

    - by John Hamelink
    I have a coordinate. I want to find the top "n" (n being a variable value) nearest coordinates out of several thousand rows stored on a MySQL database. I also want to be able to define maximum and minimum distances between the coordinate in question and the coordinates in the database. How best am I to go about this? Would it be bonkers to use PHP as I understand the syntax much better than MySQL? If I use a MySQL function, how do I move it between databases if I choose to switch servers? How is it stored? Lastly, what is the most efficient method of getting through all these coordinates accurately - the coordinates are all relatively close to one another? Thanks for your time, John.

  • strerror_r returns trash when I manually set errno during testing

    - by Robert S. Barnes
    During testing I have a mock object which sets errno = ETIMEDOUT; The object I'm testing sees the error and calls strerror_r to get back an error string: if (ret) { if (ret == EAI_SYSTEM) { char err[128]; strerror_r(errno, err, 128); err_string.assign(err); } else { err_string.assign(gai_strerror(ret)); } return ret; } I don't understand why strerror_r is returning trash. I even tried calling strerror_r(ETIMEDOUT, err, 128) directly and still got trash. I must be missing something. It seems I'm getting the gnu version of the function not the posix one, but that shouldn't make any difference in this case.

  • C# SHA-1 vs. PHP SHA-1...Different Results?

    - by Arcdigital
    Hey, I am trying to calculate a SHA-1 Hash from a string, but when I calculate the string using php's sha1 function I get something different than when I try it in C#. I need C# to calculate the same string as PHP (since the string from php is calculated by a 3rd party that I cannot modify). How can I get C# to generate the same hash as PHP? Thanks!!! String = [email protected] C# Code (Generates d32954053ee93985f5c3ca2583145668bb7ade86) string encode = secretkey + email; UnicodeEncoding UE = new UnicodeEncoding(); byte[] HashValue, MessageBytes = UE.GetBytes(encode); SHA1Managed SHhash = new SHA1Managed(); string strHex = ""; HashValue = SHhash.ComputeHash(MessageBytes); foreach(byte b in HashValue) { strHex += String.Format("{0:x2}", b); } PHP Code (Generates a9410edeaf75222d7b576c1b23ca0a9af0dffa98) sha1();

  • How do I watch a file for changes using Python?

    - by Jon Cage
    I have a log file being written by another process which I want to watch for changes. Each time a change occurrs I'd like to read the new data in to do some processing on it. What's the best way to do this? I was hoping there'd be some sort of hook from the PyWin32 library. I've found the win32file.FindNextChangeNotification function but have no idea how to ask it to watch a specific file. If anyone's done anything like this I'd be really grateful to hear how... [Edit] I should have mentioned that I was after a solution that doesn't require polling. [Edit] Curses! It seems this doesn't work over a mapped network drive. I'm guessing windows doesn't 'hear' any updates to the file the way it does on a local disk.

  • transform longitude latitude into meters

    - by Sponge
    I need a function that maps gps positions to x/y values like this: getXYpos(GeoPoint relativeNullPoint, GeoPoint p){ deltaLatitude=p.latitude-relativeNullPoint.latitude; deltaLongitude=p.longitude-relativeNullPoint.longitude; ... resultX=latitude (or west to east) distance in meters from p to relativeNullPoint resultY=longitude (or south to north) distance in meters from p to relativeNullPoint } i have seen some implementations of "distance of two geoPoints" but they all just calculate the air-line distance. i think the deltaLongitude can be transformed into meters directly but the deltaLatitude depends in the Longitude. does anyone know how this problem can be solved?

  • JavaScript setInterval loop not holding variable

    - by Ryan
    Here is my code: var showNo = 1; window.setInterval(function() { console.log(showNo); if(showNo === 1) { var nextNo = 2; } else if(showNo === 2) { var nextNo = 3; } else if(showNo === 3) { var nextNo = 4; } else if(showNo === 4) { var nextNo = 5; } else if(showNo === 5) { var nextNo = 1; } else { var showNo = 1; var nextNo = 2; } var showNo = nextNo; }, 500); My question is, why is the showNo variable not holding when the setInterval loop starts? The console displays 'undefined' in the above example. This may be a simple question, but I am trying to teach myself query and this has me stuck.. Any answers would be great. Thanks.

  • Order hybrid mixed mysql search result in one query?

    - by Fredrik
    This problem is easy fixed clientside. But for performance I want to do it directly to the database. LIST a +------+-------+-------+ | name | score | cre | +------+-------+-------+ | Abe | 3 | 1 | | Zoe | 5 | 2 | | Mye | 1 | 3 | | Joe | 3 | 4 | Want to retrieve a joined hybrid result without duplications. Zoe (1st higest score) Joe (1st last submitted) Abe (2nd highest score) Mye (2nd last submitted) ... Clientside i take each search by itself and step though them. but on 100.000+ its getting awkward. To be able to use the LIMIT function would ease things up a lot! SELECT name FROM a ORDER BY score DESC, cre DESC; SELECT name FROM a ORDER BY cre DESC, score DESC;

  • How to get progress bar to time Class exectution

    - by chrissygormley
    Hello, I am trying to use progress bar to show the progress of a script. I want it increase progress after every function in a class is executed.

  • jQuery: jquery form plugin syntax?

    - by k00k
    I'm using jquery with the jquery form plugin. I read through a bunch of posts, the docs, etc., and I'm still having trouble with what I believe to be simple. I have a form with some simple text inputs and a couple textareas, and I have this link that I want to trigger submission of that form to a specific method (/email): <a id="email-data">Send Email</a> and this jquery in doc ready: $('#email-data').click(function() { var options = { url: '/email/', success: alert('Email sent.') }; $('#report-giftcard-sales-form').ajaxSubmit(options); }); So I would expect it to submit to my /email method, but no such luck. Currently I just have the /email method logging a debug message, so it's as simple as can be. Any help is greatly appreciated.

  • PHP replace string help...

    - by MILESMIBALERR
    i am designing a site with a comment system and i would like a twitter like reply system. The if the user puts @a_registered_username i would like it to become a link to the user's profile. i think preg_replace is the function needed for this. $ALL_USERS_ROW *['USERNAME'] is the database query array for all the users and ['USERNAME'] is the username row. $content is the comment containing the @username i think this should not be very hard to solve for someone who is good at php. Does anybody have any idea how to do it?

  • Regular Expression Help - Brackets within brackets

    - by adbox
    Hello I'm trying to develop a function that can sort through a string that looks like this: Donny went to the {park|store|{beach with friends|beach alone}} so he could get a breath of freash air. What I intend to do is search the text recursively for {} patterns where there is no { or } inside the {}, so only the innermost sandwiched text is selected, where I will then run a php to array the contents and select one at random, repeating process until the whole string has been parsed, showing a complete sentence. I just cannot wrap my head around regular expressions though. Appreciate any help!

  • Generating C++ BackTraces in OS/X (10.5.7)

    - by phillipwei
    I've been utilizing backtrace and backtrace_symbols to generate programmatic stack traces for the purposes of logging/diagnosis. It seems to roughly work, however, I'm getting a little bit of mangling and there are no accompanying file/line numbers associated with each function invocation (as I'd expect within a gdb bt call or something). Here's an example: 1 leonardo 0x00006989 _ZN9ExceptionC2E13ExceptionType + 111 2 leonardo 0x00006a20 _ZN9ExceptionC1E13ExceptionType + 24 3 leonardo 0x0000ab64 _ZN5Rules11ApplyActionER16ApplicableActionR9GameState + 1060 4 leonardo 0x0000ed15 _ZN9Simulator8SimulateEv + 2179 5 leonardo 0x0000eec9 _ZN9Simulator8SimulateEi + 37 6 leonardo 0x00009729 main + 45 7 leonardo 0x000025c6 start + 54 Anything I'm missing something, doing something silly, or is this all I can expect out of backtrace on OS/X? Some other tidbits: I don't see a rdynamic link option for the g++ version (4.0.1) I'm using. -g/-g3 doesn't make any difference. abi::__cxa__demangle doesn't seem to do anything

  • calculated colum or stored proceedure or just php funcion needed ?

    - by mcgrailm
    I have an order table in MySQL database and is has a field/column which store the dattime stamp of when the order was placed and I need to calculate when the order must be shipped. I could probably figure out how to right a function to calculate the ship date and call that when ever needed but I think, not sure it may moake more sense to have the shipdate as a column that is somehow calculate in mysql. that being said I have Never used a stored procedure or created a calculated field. the later I think would be best but again not sure. I used to make calculated field all the time in FMP but I've gotten away from that program. if someone could point me in the right direction or tell me why it would be better to do it one way over another I'd appreciate it . thanks Mike

  • Can one TabBarItem be used for two different ViewControllers?

    - by Kash
    I am creating an app with three tabBarItems, but I want to control four ViewControlers with three tabBars. I am trying to use one tabBar for two different viewcontrollers. I am able to change the tabBartitle and icon upon tap, but I cannot reset it so it can go back to it's previous status with previous title and icon. Also, I am confused about using the tabBarController or just tabBar and to call what function to reload/refresh the tabBar status and where exactly? I am fairly new to the iPhone SD, please describe your answer clearly any help will be highly appreciated.

  • What is the ideal length of an URL slug

    - by Sinan
    To make pretty URL's from article titles I am using a simple function. However lately I an concerned about the ideal length of these "slugs". It is said that too many dashes are bad. However some article titles can be long and a too long URL may not be liked by google. Of course that defeats th whole idea of having URL slugs. So does anyone have any idea how long a URL slug should be. Should there be a limit on the "dash" charecters used?

  • Php deliberately awkward?

    - by Jonathan
    I'm trying to create a login process (as people who have answered my previous question will know) But it seems impossible to create one process that will work with a desktop app and a standard website. Instead I have the login function in Usermanagement.php (which is a class, icyntk) but then in another php file (api/login.php) I have: <?php require_once '../usermanagement.php'; $m = new usermanage(); echo $m->login($_POST['username'], $_POST['password']); ?> And then I will still need to make another login.php just to be used with the login form on the website. As I can't see anyway to get the result (the echo) of the api/login.php script from the index.php file (where the login form is, it only has HTML in though) Is there anyway I can simplify this so I only need one login.php?

  • MOSS Collect Data from user custom email

    - by nav
    Hi, I am trying to send out a custom email, after the Collect Data from user step in my primary workflow which starts when an item in list X is created. I have created a secondary workflow to start when a new Task item is created (this is created by the Collect Data from user action in the primary workflow). But I am having problem how I retrieve the information on the list X. I know the ID of the referenced item in List X is stored in a URL within the "Link" column in the Tasks lists. But can't see any string manipulation function that will grab this ID so I can use it to link back to relevant item in List X. Is there an easier way to do this? Many Thanks, Nav

  • How do I generate different yyparse functions from lex/yacc for use in the same program?

    - by th
    Hi, I want to generate two separate parsing functions from lex/yacc. Normally yacc gives you a function yyparse() that you can call when you need to do some parsing, but I need to have several different yyparses each associated with different lexers and grammars. The man page seems to suggest the -p (prefix) flag, but this didn't work for me. I got errors from gcc that indicated that yylval was not properly being relabeled (i.e. it claims that several different tokens are not defined). Does anyone know the general rpocedure for generating these separate functions? thanks

  • Need a formula for calculating the tax portion of a total amount.

    - by pawz
    In Australia we have to advertise products with tax already added, so rather than say a product is $10 + $1 GST = $11, we normally work backwards and say "ok, total is $10, how much of that is GST ?" For example, for a $10 total, you do 10 * (1 /11) = 0.91, which is the tax component of the $10 total. My problem is I need calculate a formula for working out the taxable component when the tax rate is a variable. So far I've made this calculation although I'm not sure how correct an assertion it is: 10 * (1 / x) = 0.09 * (1 / y) where y = 10, x = 11 Basically i want to work out x on the left hand side when I know that the tax rate is 0.05 for example, which will give me a formula that I can use to calculate the taxable component of an total figure. I want a function into which I can plug in the total price and the tax rate, and get back the taxable component of the total price. I'd really appreciate the help with this as it really makes my head hurt ! :")

  • GWT application throws an exception when run on Google Chrome with compiler output style set to 'OBF

    - by Elifarley
    I'd like to know if you guys have faced the same problem I'm facing, and how you are dealing with it. Sometimes, a small and harmless change in a Java class ensues strange errors at runtime. These errors only happen if BOTH conditions below are true: 2) the application is run on Google Chrome, and 1) the GWT JavaScript compiler output style is set to 'OBF'. So, running the application on Firefox or IE always works. Running with the output style set to 'pretty' or 'detailed' always works, even on Google Chrome. Here's an example of error message that I got: "((TypeError): Property 'top' of object [object DOMWindow] is not a function stack" And here's what I have: - GWT 1.5.3 - GXT 1.2.4 - Google Chrome 4 and 5 - Windows XP In order to get rid of this Heisenbug, I have to either deploy my application without obfuscation or endure a time-consuming trial-and-error process in which I re-implement the change in slightly different ways and re-run the application, until the GWT compiler is happy with my code. Would you have a better idea on how to avoid this?

  • Stop default hashtag behavior with jquery

    - by scatteredbomb
    I'm using the following code to append a hashtag to the end of a url. That way someone can copy that url and take them back to that page, with certain divs visable. $("a.live").click(function() { window.location.hash = 'live'; $("#live).slideDown(); }); In this example I have a div called 'live', that would slideDown when a link is clicked, and '#live' added to the url. Then I have code that checks the hash tags when the page is loaded to show the proper divs. My problem is, how do I prevent the browser from jumping to the 'live' div once it's called? I don't want the page to scroll down to the div, just want it opened and the hashtag appended so a person could copy it and come back to that page with that div showing. Any tips? Thank you!
