  • using nested arrays by php http_build_query() and recieve them in flash AS3

    - by Mahmoud
    hi, i am having this hard time figuring what is needed to do, i am using URLVariables to send/recieve values between flash and PHP the problem is, i am unable to access nested arrays ( array inside an array ) with flash heres an example: $dgresult = array("total" = $results); echo http_build_query($dgresult,"flf_"); in flash, all i need to do is to use: var variables:URLVariables = new URLVariables(e.target.data); then i can access it with : variables.total the problem now is when i have nested arrays: $dgresult = array("total" = $results); array_push($dgresult,$another_array); http_build_query($dgresult,"flf_"); i can still access variables.total but what about anything that has flf_ ? how is that possible?

  • Javascript calling JSF handler method

    - by msharma
    Hi All, I am reading an xml file using javascript and then I need to submit my form so that it calls a particular method in my JSF handler. Usually this can be done on a jsp when user clicks a button by having an actionlistener like so: <h:commandLink styleClass="button" action="#{myHandler.outcome}" actionListener="#{myHandler.doNext}"> <span><h:outputText value="#{text.button_submit}" /></span> </h:commandLink> I am not sure how to call a method like 'doNext' above in the handler from javascript. I cannot do a simple: document.form.submit(); as it then repeats the processing i have already done. I want to read values from an xml file and then call a particular method in handler. Any ideas much appreciated.

  • Parsing complex string using regex

    - by wojtek_z
    My regex skills are not very good and recently a new data element has thrown my parser into a loop Take the following string "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write" Previously I had the following for my regex : [+\\-/] Which would turn the result into USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read But now I have values with dashes in them which is causing bad output New string looks like "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write/FUNCTION=Read-Write" Which gives me the following result , and breaks the key = value structure. USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read Write Can someone help me formulate a valid regex for handling this or point me to some key / value examples. Basically I need to be able to handle + - / signs in order to get combinations.

  • Improve mysql JDBC insert call

    - by richs
    i have a legacy Java system that every time it gets an order it makes a JDBC call to a stored procedure for each field in the order. Generally the stored procedure will get called 20 to 30 times for each order. The store procedure is just doing an insert into a table for each field. i need to improve the performance of this operation. one thought i had was to create an insert query string that does multiple inserts in one JDBC call. MySql supports a multiple insert string. INSERT INTO PersonAge (name, age) VALUES ('Helen', 24), ('Katrina', 21), ('Samia', 22), ('Hui Ling', 25), ('Yumie', 29) This has the advantage of only requiring one JDBC call per order. Any other ideas on how to improve performance?

  • a question on common lisp

    - by kostas
    Hello people, I'm getting crazy with a small problem here, I keep getting an error and I cant seem to figure out why, the code is supposed to change the range of a list, so if we give it a list with values (1 2 3 4) and we want to change the range in 11 to fourteen the result would be (11 12 13 14) the problem is that the last function called scale-list will give back an error saying: Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil) anybody has a clue why? I use aquamacs as an editor thanks in advance ;;finds minimum in a list (defun minimum(list) (car (sort list #'<))) ;;finds maximum in a list (defun maximum(list) (car (sort list #'>))) ;;calculates the range of a list (defun range(list) (- (maximum list) (minimum list))) ;;this codes scales a value from a list (defun scale-value(list low high n) (+ (/ (* (- (nth (- n 1) list) (minimum list)) (- high low)) (range list)) low)) ;and this code is supposed to scale the whole list (defun scale-list(list low high n) (unless (= n 0) (cons (scale-value list low high n) (scale-list list low high (- n 1))))) (scale-list '(0.1 0.3 0.5 0.9) 20 30 4)

  • Reversed Latitude/Longitude US Tiger/Line Shape File to MySQL w/ OGR2OGRP

    - by Dave LeJeune
    Hi - I've downloaded the latest set (2010) of TIGER edge shape files (ESRI shapefile format) from the US Census website and am loading them into MySQL using the GDAL ogr2ogr utility. A new table (geotest) does get created with a SHAPE column that has the geometry defined as a LINESTRING. However, I am seeing reversed latitude and longitude values that get reversed when running the following command: ogr2ogr -f "MySQL" MySQL:"geo,user=lejeuned,host=localhost,password=cnickl234" -nln geotest -nlt LINESTRING -append -a_srs "EPSG:4326" -lco engine=MYISAM tl_2010_01021_edges.shp Mapping the latitude/longitude (after reversing them of course) they appear to be spot on so I suspect there is just something I am doing wrong or flag I am missing which is causing the latitude and longitudes to be transposed. When I select the SHAPE column using astext() I get the following result: LINESTRING(-86.69863 32.973164,-86.69853 32.97302,-86.69856 32.97287,-86.698613 32.972825,-86.6988 32.972825,-86.6989 32.972892,-86.6989 32.973002,-86.69874 32.97316,-86.69864 32.97318,-86.69863 32.973164) Any ideas what I am doing wrong?

  • What is the `name` keyword in JavaScript?

    - by Joey Adams
    When I typed this apparently innocent snippet of code: values.name gedit highlighted name as a keyword. However, name is not listed by the pages linked to by an answer to a question about reserved keywords. I also did a couple trivial tests in SpiderMonkey, but name seemed to act like an ordinary identifier. A Google search didn't tell me much either. However, I did find a page listing name in "Other JavaScript Keywords". My guess is that name is a function or a member of some DOM element and does not intrude on the namespace. Is name really a keyword in JavaScript? If so, what does it do?

  • Ruby on Rails: strange voting increment behavior

    - by Justin Meltzer
    So I have an up and a downvote button that inserts a vote with a value of 1 or -1 into the database. This works correctly. Then, I display the total vote count for that element by summing up its votes' values. However, this isn't working correctly, because the vote sum display is acting really strange: The first vote on a video doesn't seem to increment it at all. Then the second vote does. If I go from an upvote to a downvote, it increments up once, and then the next downvote is down. This is difficult to explain, but maybe you can figure out what is wrong with my code. I have this function in my Video model (the element that is voted on, it has_many video_votes): def vote_sum read_attribute(:vote_sum) || video_votes.sum(:value) end I also have this in my VideoVote model: after_create :update_vote_sum private def update_vote_sum video.update_attributes(:vote_sum => video.vote_sum + value) end What am I doing wrong?

  • Issue with child of custom Decorator class in WPF

    - by galacticgrug
    I need a custom border that renders a little differently than a normal border. I made a class that inherited from Decorator as follows class BetterBorder : Decorator { protected override Size ArrangeOverride(Size arrangeSize) { return arrangeSize; } protected override void OnRender(DrawingContext dc) { //these values are calculated elsewhere dc.DrawGeometry(backgroundBrush, borderPen, pathGeometry); } } //Properties and helper methods below this All of this works fine until I try to add a child to the control, the control can be added but is not visible and seems to be moved off BetterBorders visible client area. If I inherit from Border everything works fine, what am I missing?

  • winforms - gridview cell timespan edit problem

    - by Sharique
    I'm following this question for formatting timespan value in the gridview. Format TimeSpan in DataGridView column I'm diaplying only minutes value in grid as follows DataGridViewColumn idleTimeColumn = myGridView.Columns["IdleTime"]; idleTimeColumn.DefaultCellStyle.FormatProvider = new TimeSpanFormatter(); idleTimeColumn.DefaultCellStyle.Format = "m"; This cell is editable, so when I enter 5 (that mean 5 min) in the cell, then it should take it minute, but it take it as day value (ie, 5.00:00:00). I tried different values for format (mm,%m) but all these gives the same output.

  • how to use found_rows in oracle package to avoid two queries

    - by Omnipresent
    I made a package which I can use like this: select * from table(my_package.my_function(99, 'something, something2', 1, 50)) I make use of the package in a stored procedure. Sample stored procedure looks like: insert into something values(...) from (select * from table(my_package.my_function(99, 'something, something2', 1, 50))) a other_table b where b.something1 = a.something1; open cv_1 for select count(*) from table(my_package.my_function(99, 'something, something2', 1, 50)) So I am calling the same package twice. first time to match records with other tables and other stuff and second time to get the count. Is there a way to get the count first time around and put it into a variable and second time around I just pick that variable rather than calling the whole query again? Hope it makes sense.

  • Displaying desired properties from search results with grails compass

    - by ombud
    Hi, I've been stumped with the problem of displaying a selected set of properties returned as a result via a Compass query in grails. I have 300 columns in my domain class and what I'd like to do is to return ONLY THOSE values I specify (around 10 - 15 properties/fields/columns). All the 300 columns have been indexed, btw. I know I can do this using Lucene by cycling through returned hits and selectively calling a=getField(column_name), et c. My qiuestion is, how do I do the same thing using thee Compass Grails plugin ? Any help will gratefully be appreciated. Thanks in anticipation, Ombud

  • oracle pl sql dump result into file

    - by CC
    Hi. I'm working on a pl sql stored procedure. What I need is to do a select, use a cursor and for every record build a string using values. At the end I need to write this into a file. I try to use dbms_output.put_line("toto") but the buffer size is to small because I have about 14 millions lines. I call my procedure from a unix ksh. I'm thinking at something like using "spool on" (on the ksh side) to dump the result of my procedure, but I don' know how to do it (if this is possible) Anyone has any idea? Thank alot. C.C.

  • Why can't I set a custom color-tint for the UINavigationBar?

    - by mobibob
    I want to change the color on the navigation bar and the documentation states not to attempt to change the 'alpha' value. So, how can I set a color that is not the SDK defined values (e.g., [UIColor redColor], brownColor, etc.) if all the constructors provide an alpha value? I tried getting the current alpha value but that did not help. When I use a custom color, it causes the navigation bar to look like an x-ray (a scraggy, black-on-white). [self.navigationController.navigationBar setTintColor: [UIColor brownColor]];

  • SQL: Need to SUM on results that meet a HAVING statement

    - by Wasauce
    I have a table where we record per user values like money_spent, money_spent_on_candy and the date. So the columns in this table (let's call it MoneyTable) would be: UserId Money_Spent Money_Spent_On_Candy Date My goal is to SUM the total amount of money_spent -- but only for those users where they have spent more than 10% of their total money spent for the date range on candy. What would that query be? I know how to select the Users that have this -- and then I can output the data and sum that by hand but I would like to do this in one single query. Here would be the query to pull the sum of Spend per user for only the users that have spent 10% of their money on candy. SELECT UserId, SUM(Money_Spent), SUM(Money_Spent_On_Candy) / SUM(Money_Spent) AS PercentCandySpend FROM MoneyTable WHERE DATE >= '2010-01-01' HAVING PercentCandySpend > 0.1;

  • How to mock/stub calls to message taglib in Grails controller

    - by Dave
    I've got a Grails controller which relies on the message taglib to resolve an i18n message: class TokenController { def passwordReset = { def token = DatedToken.findById(params.id); if (!isValidToken(token, params)) { flash.message = message(code: "forgotPassword.reset.invalidToken") redirect controller: 'forgotPassword', action: 'index' return } render view:'/forgotPassword/reset', model: [token: token.token] } } I've written a unit test for the controller: class TokenControllerTests extends ControllerUnitTestCase { void testPasswordResetInvalidTokenRedirect() { controller.passwordReset() assert... } } Since the message taglib is called in the controller I get a MissingMethodException: groovy.lang.MissingMethodException: No signature of method: TokenController.message() is applicable for argument types: (java.util.LinkedHashMap) values: [[code:forgotPassword.reset.invalidToken]] Does anyone know the best way to get around this issue in a unit test? Ideally I would like to perform assertions on the message but right now I'd be happy if the test just ran! Thanks

  • How do I prevent jagged edges alongside the surfaces of my 3d model?

    - by badcodenotreat
    Lets say I've implemented in openGL a crude model viewer with shading which renders a series of blocks, such that I have something that looks like this. http://i.imgur.com/TsF7K.jpg Whenever I rotate my model to the side, it causes an unwanted jagged effect along any surface with a steep viewing angle. http://i.imgur.com/Bgl9o.jpg I'm pretty sure this is due to the polygon offset I used to prevent z-fighting between the model and the wireframe, however I'm not able to find the factor/unit parameters in openGL which prevent this unwanted effect. what are the best values of factor and unit for glPolygonOffset to prevent this? would implementing anti-aliasing alleviate the problem? is the trade off in performance trivial/significant? is this perhaps a shading issue? should i try a solution along this line of thought?

  • Web Services: more frequent "small" calls, or less frequent "big" calls

    - by Klay
    In general, is it better to have a web application make lots of calls to a web service getting smaller chunks of data back, or to have the web app make fewer calls and get larger chunks of data? In particular, I'm building a Silverlight app that needs to get large amounts of data back from the server in response to a query created by a user. Each query could return anywhere from a few hundred records to a few thousand. Each record has around thirty fields of mostly decimal-type data. I've run into the situation before where the payload size of the response exceeded the maximum allowed by the service. I'm wondering whether it's better (more efficient for the server/client/web service) to cut this payload vertically--getting all values for a single field with each call--or horizontally--getting batches of complete records with each call. Or does it matter?

  • Decrease DB requests number from Django templates

    - by Andrew
    I publish discount offers for my city. Offer models are passed to template ( ~15 offers per page). Every offer has lot of items(every item has FK to it's offer), thus i have to make huge number of DB request from template. {% for item in offer.1 %} {{item.descr}} {{item.start_date}} {{item.price|floatformat}} {%if not item.tax_included %}{%trans "Without taxes"%}{%endif%} <a href="{{item.offer.wwwlink}}" >{%trans "Buy now!"%}</a> </div> <div class="clear"></div> {% endfor %} So there are ~200-400 DB requests per page, that's abnormal i expect. In django code it is possible to use select_related to prepopulate needed values, how can i decrease number of requests in template?

  • Is there a COM object that just implements IUnknown I can use?

    - by Matt
    For an asynchronous Windows API, I can provide an IUnknown state parameter to associate calls to the API with calls from the callback. It's my understanding that COM guarantees that two IUnknown pointers to the same object will be of the same value. Thus, if I only want to associate API calls with callbacks, IUnknown should be all I need, by comparing the values of the pointers. Is there a stock implementation of IUnknown I can use? Of course it would be trivial to implement myself, but for such a base component of COM, I'm wondering if Windows or ATL provides one I should use instead. Thanks, --Matt

  • Write data to an xml file.

    - by Bobby
    My aim is to write an XML file with few tags whose values are the regional language. I'm using Python to do this and using IDLE(Pythong GUI) for programming. While I try to write the words in an xmls file it gives the following error. UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-4: ordinal not in range(128) For now, I'm not using any xml writer library instead I'm opening a file "test.xml" and writing the data into it. This error is encountered by the line: f.write("\t\" + data + "\"). If I replace the above write statement with print statement then it prints the data properly on Python Shell. I'm reading the data from an excel file which is not in the UTF8,16, or 32 encoding formats. Its in some other format. cp1252 is reading the data properly. Any help in getting this data writtent oan xml would be highly appreciated. Thanks in advance. Bob

  • How do I use a Rails ActiveRecord migration to insert a primary key into a MySQL database?

    - by Terry Lorber
    I need to create an AR migration for a table of image files. The images are being checked into the source tree, and should act like attachment_fu files. That being the case, I'm creating a hierarchy for them under /public/system. Because of the way attachment_fu generates links, I need to use the directory naming convention to insert primary key values. How do I override the auto-increment in MySQL as well as any Rails magic so that I can do something like this: image = Image.create(:id => 42, :filename => "foo.jpg") image.id #=> 42

  • Grails Unit Tests: Why does this statement fail?

    - by leeand00
    I've developed in Java in the past, and now I'm trying to learn Grails/Groovy using this slightly dated tutorial. import grails.test.* class DateTagLibTests extends TagLibUnitTestCase { def dateTagLib protected void setUp() { super.setUp() dateTagLib = new DateTagLib() } protected void tearDown() { super.tearDown() } void testThisYear() { String expected = Calendar.getInstance().get(Calendar.YEAR) // NOTE: This statement fails assertEquals("the years dont match and I dont know why.", expected, dateTagLib.thisYear()) } } DateTagLibTests.groovy (Note: this TagLibUnitTestCase is for Grails 1.2.1 and not the version used in the tutorial) For some reason the above test fails with: expected:<2010 but was:<2010 I've tried replacing the test above with the following alternate version of the test, and the test passes just fine: void testThisYear() { String expected = Calendar.getInstance().get(Calendar.YEAR) String actual = dateTagLib.thisYear() // NOTE: The following two assertions work: assertEquals("the years don\'t match", expected, actual) assertTrue("the years don\'t match", expected.equals(actual)) } These two versions of the test are basically the same thing right? Unless there's something new in Grails 1.2.1 or Groovy that I'm not understanding. They should be of the same type because the values are both the value returned by Calendar.getInstance().get(Calendar.YEAR)
