  • How would you organize this in asp.net mvc?

    - by chobo
    I have an asp.net mvc 2.0 application that contains Areas/Modules like calendar, admin, etc... There may be cases where more than one area needs to access the same Repo, so I am not sure where to put the Data Access Layers and Repositories. First Option: Should I create Data Access Layer files (Linq to SQL in my case) with their accompanying Repositories for each area, so each area only contains the Tables, and Repositories needed by those areas. The benefit is that everything needed to run that module is one place, so it is more encapsulated (in my mind anyway). The downside is that I may have duplicate queries, because other modules may use the same query. Second Option Or, would it be better to place the DAL and Repositories outside the Area's and treat them as Global? The advantage is I won't have any duplicate queries, but I may be loading a lot of unnecessary queries and DAL tables up for certain modules. It is also more work to reuse or modify these modules for future projects (though the chance of reusing them is slim to none :)) Which option makes more sense? If someone has a better way I'd love to hear it. Thanks!

  • Get XML-RPC (Andorid - PHP) web service different params type

    - by Jovan
    Hi, I want to create XML-RPC web service for Andorid (client) - PHP (Server) communication I create XML-RPC PHP web service server using this tutorial: http://articles.sitepoint.com/article/own-web-service-php-xml-rpc/5 For andorid client web service I use this project: http://code.google.com/p/android-xmlrpc/ server and client communication is OK, but I have problem with getting params from andorid client to php server. From andorid client I send two params (first integer and second float number) Object[] params = { 3, 3.6f, }; method.call(params); , but I don't know how to handle this parameters in php server?? in php server there is some function , but with only one param ($news_id): function news_viewNewsItem ( $news_id ) { /* Define the query to fetch the news item */ $query = "SELECT * FROM kd_xmlrpc_news WHERE news_id = '" . $news_id . "'"; $sql = mysql_query ( $query ); if ( $result = mysql_fetch_array ( $sql ) ) { /* Extract the variables for sending in our server response */ $news_item['news_id'] = $result['news_id']; $news_item['date'] = XMLRPC_convert_timestamp_to_iso8601( mysql_datetime_to_timestamp( $result['date'] ) ); $news_item['title'] = $result['title']; $news_item['full_desc'] = $result['full_desc']; $news_item['author'] = $result['author']; /* Respond to the client with the news item */ XMLRPC_response(XMLRPC_prepare($news_item), KD_XMLRPC_USERAGENT); } else { /* If there was an error, respond with a fault code instead */ XMLRPC_error("1", "news_viewNewsItem() error: Unable to read news:" . mysql_error(), KD_XMLRPC_USERAGENT); } } In server.py file there is functions for every method but I dont know how to write in php server: def add(self, x, y): print print "input x=%s, y=%s" % (str(x), str(y)) sum = x + y print "output", sum print return sum Can some one help me with code , and tell me how to handle various types from client to server?? Thanks and Happy New Year

  • Survey statistic diagram ideas

    - by Nort
    Hey everyone, I've got some homework tasks in topic surveys and diagrams. The first task is to normalize the input of a survey, because the structure of the data is changing from time-to-time. So there are three types of surveys: static fields, where text is stored dynamic ones, where the user can select one option and multiselect fields, where the user can select multiple options So I'm not really a statistics guy, so I have really no idea what I can do with that incomming data. So the data I have is stored in an orbital XML file from there I can easily get how man times a survey was filled, and how many times a field was filled, so I can (for eg on a pie chart show the relation of filled or not filled). The second idea is to show the relation between the content of a multi option element using a bar chart or so. In case of the multi option elements I've got the idea to show data in implication of one option. But the question is, what could be shown? The other problem are the static elements (text fields and so). What data could be represented from a single field? The data in the XML field is collected from 2001 to 2005 So maybe I can work with the dates of the surveys, but as I said, i don't really know how to process the data, to collect as much data as possible.

  • Groovy & Grails Concurrency ( quartz, executor )

    - by Pietro
    What I'm trying to do is to run multiple threads at some starting time. Those threads must stay alive for 90minutes after start. During the 90minutes they execute something after a random sleep time (ex: 5minutes to 15minutes). Here is a pseudo code on how I would implement it. The problem is that doing it in this way the threads run in an unexpected way. How can I implement correctly something like this? Class MyJob { static triggers = { cron name: 'first', cronExpression: "0 30 21 * * FRI" cron name: 'second', cronExpression: "0 30 19 * * FRI" cron name: 'third', cronExpression: "0 30 17 * * FRI" def myService def execute() { switch( between trigger name ) case 'first': model = Model.findByAttribute(...) ... myService.run( model, start_time ) break; ... } } class MyService { def run( model, start_time ) { def end_time = end_time.plusMinutes(90) model.fields.each( field -> Thread.start { executeSomeTasks( field, start_time, end_time ) } ) } def executeSomeTasks( field, start_time, end_time ) { while( start_time < end_time ) { ...do something ... sleep( Random.nextInt( 1000 ) ); } } }

  • How do you submit an authenticated HTML form using XUL (Firefox extension) Javascript?

    - by machineghost
    I am working on a Firefox extension, and in that extension I am trying to use AJAX to submit a form on a webpage. I am using: var request = Components.classes["@mozilla.org/xmlextras/xmlhttprequest;1"].createInstance(Components.interfaces.nsIXMLHttpRequest); request.onload = loadHandler; request.open("POST", url, true); request.send(values); to make the request, and it works ... mostly. The one problem is that the form has an authentication token on it, and I need to submit that token with my POST. I tried doing a GET separately to get this token, but by the time I made my second (POST) request my session had (evidently) changed, and the authenticity token was considered invalid. Does anyone know of a way to use the XUL/Chrome Javscript to maintain a constant session across multiple requests (all "behind the scenes") for something this? I'm still a XUL n00b, so there may be a totally obvious alternative that I'm missing (eg. hidden IFRAME; I tried that briefly but couldn't get it to work).

  • Best implementation of Java Queue?

    - by Georges Oates Larsen
    I am working (In java) on a recursive image processing algorithm that recursively traverses the pixels of the image, outward from a center point. Unfortunately... That causes stack overflows, so I have decided to switch to a Queue-based algorithm. Now, this is all fine and dandy -- But considering the fact that its queue will be analyzing THOUSANDS of pixels in a very short amount of time, while constantly popping and pushing, WITHOUT maintaining a predictable state (It could be anywhere between length 100, and 20000); The queue implementation needs to have significantly fast popping and pushing abilities. A linked list seems attractive due to its ability to push elements unto its self without rearranging anything else in the list, but in order for it to be fast enough, it would need easy access to both its head, AND its tail (or second-to-last node if it were not doubly-linked). Sadly, though I cannot find any information related to the underlying implementation of linked lists in Java, so it's hard to say if a linked list is really the way to go... This brings me to my question... What would be the best implementation of the Queue interface in Java for what I intend to do? (I do not wish to edit or even access anything other than the head and tail of the queue -- I do not wish to do any sort of rearranging, or anything. On the flip side, I DO intend to do a lot of pushing and popping, and the queue will be changing size quite a bit, so preallocating would be inefficient)

  • Syncing two AS3 NetStreams

    - by Lowgain
    I'm writing an app that requires an audio stream to be recording while a backing track is played. I have this working, but there is an inconsistent gap in between playback and record starting. I don't know if I can do anything to make the sync perfect every time, so I've been trying to track what time each stream starts so I can calculate the delay and trim it server-side. This also has proved to be a challenge as no events seem to be sent when a connection starts (as far as I know). I've tried using various properties like the streams' buffer sizes, etc. I'm thinking now that as my recorded audio is only mono, I may be able to put some kind of 'control signal' on the second stereo track which I could use to determine exactly when a sound starts recording (or stick the whole backing track in that channel so I can sync them that way). This leaves me with the new problem of properly injecting this sound into the NetStream. If anyone has any idea whether or not any of these ideas will work, how to execute them, or some alternatives, that would be extremely helpful! Been working on this issue for awhile

  • How to hide div serverside by reading cookie

    - by user338109
    I am using following a tutorial from here: http://www.shopdev.co.uk/blog/cookies-with-jquery-designing-collapsible-layouts/ This is the script I use: <script type="text/javascript" language="javascript"> $(function() { // SETUP: // When the info banner is clicked: $('#setup').click(function() { $('#intro').css("display","none"); $.cookie('intro', 'collapsed'); }); // COOKIES // Info banner state var intro = $.cookie('intro'); // READ THE COOKIES if (intro == 'collapsed') { $('#intro').css("display","none"); }; }); </script> The script hides the following div as the cookie is read: <div class="feedback attention" id="intro"> Text goes here <a id="setup" href="#">Ok I get it, please hide this</a> </div> Everything work great but when the page loads the div is shown for a split second. I guess the solution is to present two different pieces of markup serverside according to the cookie info. I have no idea how to go about this.

  • How can I rewrite the history of a published git branch in multiple steps?

    - by Frerich Raabe
    I've got a git repository with two branches, master and amazing_new_feature. The latter branch contains the work on, well, an amazing new feature. A colleague and me are both working on the same repository, and the two of us commit to both branches. Now the work on the amazing new feature finished, and a bit more than 100 commits were accumulated in the amazing_new_feature branch. I'd like to clean those commits up a bit (using git rebase -i) before merging the work into master. The issue we're facing is that it's quite a pain to rewrite/reorder all 100 commits in one go. Instead, what I'd like to do is: Rewrite/merge/reorder the first few commits in the amazing_new_feature branch and put the result into a dedicated branch which contains the 'cleaned up' history (say, a amazing_new_feature_ready_for_merge branch). Rebase the remaining amazing_new_feature branch on the amazing_new_feature_ready_for_merge branch. Repeat at 1. My idea is that at some point, all the work from amazing_new_feature should be in amazing_new_feature_ready_for_merge and then I can merge the latter into master. Is this a sensible approach, or are there better/easier/more fool-proff solutions to this problem? I'm especially scared about the second step of the above algorithm since it means rebasing a published branch. IIRC it's a dangerous thing to do.

  • How do I bind to a custom view in Cocoa using Xcode 4?

    - by Newt
    I'm a beginner when it comes to writing Mac apps and working with Cocoa, so please forgive my ignorance. I'm looking to create a custom view, that exposes some properties, which I can then bind to an NSObjectController. Since it's a custom view, the Bindings Inspector obviously doesn't list any of the properties I've added to the view that I can then bind to using Interface Builder. After turning to the Stackoverflow/Google for help, I've stumbled across a couple of possible solutions, but neither seem to be quite right for my situation. The first suggested creating an IBPlugin, which would then mean my bindings would be available in the Bindings Inspector. I could then bind the view to the controller using IB. Apparently IBPlugins aren't supported in Xcode 4, so that one's out the window. I'm also assuming (maybe wrongly) that IBPlugins are no longer supported because there's a better way of doing such things these days? The second option was to bind the controller to the view programmatically. I'm a bit confused as to exactly how I would achieve this. Would it require subclassing NSObjectController so I can add the calls to bind to the view? Would I need to add anything to the view to support this? Some examples I've seen say you'd need to override the bind method, and others say you don't. Also, I've noticed that some example custom views call [self exposeBinding:@"bindingName"] in the initializer. From what I gather from various sources, this is something that's related to IBPlugins and isn't something I need to do if I'm not using them. Is that correct? I've found a post on Stackoverflow here which seems to discuss something very similar to my problem, but there wasn't any clear winner as to the best answer. The last comment by noa on 12th Sept seems interesting, although they mention you should be calling exposeBinding:. Is this comment along the right track? Is the call to exposeBinding really necessary? Apologies for any dumb questions. Any help greatly appreciated.

  • Why does this Haskell code produce the "infinite type" error?

    - by Charlie Flowers
    I am new to Haskell and facing a "cannot construct infinite type" error that I cannot make sense of. In fact, beyond that, I have not been able to find a good explanation of what this error even means, so if you could go beyond my basic question and explain the "infinite type" error, I'd really appreciate it. Here's the code: intersperse :: a -> [[a]] -> [a] -- intersperse '*' ["foo","bar","baz","quux"] -- should produce the following: -- "foo*bar*baz*quux" -- intersperse -99 [ [1,2,3],[4,5,6],[7,8,9]] -- should produce the following: -- [1,2,3,-99,4,5,6,-99,7,8,9] intersperse _ [] = [] intersperse _ [x] = x intersperse s (x:y:xs) = x:s:y:intersperse s xs And here's the error trying to load it into the interpreter: Prelude :load ./chapter.3.ending.real.world.haskell.exercises.hs [1 of 1] Compiling Main ( chapter.3.ending.real.world.haskell.exercises.hs, interpreted ) chapter.3.ending.real.world.haskell.exercises.hs:147:0: Occurs check: cannot construct the infinite type: a = [a] When generalising the type(s) for `intersperse' Failed, modules loaded: none. Thanks. EDIT: Thanks to the responses, I have corrected the code and I also have a general guideline for dealing with the "infinite type" error in Haskell: Corrected code intersperse _ [] = [] intersperse _ [x] = x intersperse s (x:xs) = x ++ s:intersperse s xs What the problem was: My type signature states that the second parameter to intersperse is a list of lists. Therefore, when I pattern matched against "s (x:y:xs)", x and y became lists. And yet I was treating x and y as elements, not lists. Guideline for dealing with the "infinite type" error: Most of the time, when you get this error, you have forgotten the types of the various variables you're dealing with, and you have attempted to use a variable as if it were some other type than what it is. Look carefully at what type everything is versus how you're using it, and this will usually uncover the problem.

  • Access denied from another thread

    - by Lobuno
    Hello! In a program I span a thread ("the working thread"). Hera I copy some files write some data to a database and eventually, delete some other files or directories. Everything works fine. The problem is now, that I decided to move the deleting operation to some other thread. So the working thread now copies the files or directories, writes to the database, and , if there is a need to delete some other files this thread spans another thread and that second thread deleted the needed files or directories. The problem is that,the deletion used to work 100% when done in the working thread, now when the same is done in the secondary thread, I sometimes get an "Access denied" error and the files cannot be deleted. And no, the working thread is definitely NOT acceding the files and directories to delete at this moment. Sometimes (but not always) the main thread is impersonating some user, so if needed , the deleting thread is also running under impersonation just to grant the needed permissions to delete the files, so that should not be the problem. Anybody has a clue why this could be happening?

  • PHP Combo Box AJAX Refresh

    - by bhs
    I have a PHP page that currently has 4 years of team positions in columns on the page. The client wants to select the players in positions and have first, second and thrid choices. Currently the page shows 4 columns with sets of combos for each position. Each combo has a full set of players in it and the user chooses the player he wants from the combos. On submit the player positions are stored in the database. However, the client now wants to change the page so that when he selects a player in a year and position then the player is removed from the combo and can no longer be selected for that year. I've used a bit of AJAX but was wondering if anyone had any thoughts/suggestions. The page is currently quite slow so they want it speeded up as well. The page layout is currently like this POISTION YEAR1 YEAR2 YEAR3 YEAR4 1 COMBOC1 COMBOC1 COMBOC1 COMBOC1 COMBOC2 COMBOC2 COMBOC2 COMBOC2 COMBOC3 COMBOC3 COMBOC3 COMBOC3 2 same as above COMBOC1, 2 and 3 all currently have the same players - when a player is selected it needs to be removed for all combos below it. I was thinking of starting by changing the page design and having text boxes for the players and a single player select under each year like this: POISTION YEAR1 YEAR2 YEAR3 YEAR4 1 <PLAYER><POSITION><CHOICE> ... [TEXT BOX CHOICE1] [TEXT BOX CHOICE2] [TEXT BOX CHOICE3] 2 ... Then I only have 1 combo box for each year to worry about - I do however have the same problem of refreshing the combo box and removing the player that has been selected, and I'd prefer to do it withough a page submit. Sorry for the long posting - cheers

  • Creating a new object destroys an older object with different name in C++

    - by Mikael
    First question here! So, I am having some problems with pointers in Visual C++ 2008. I'm writing a program which will control six cameras and do some processing on them so to clean things up I have created a Camera Manager class. This class handles all operations which will be carried out on all the cameras. Below this is a Camera class which interacts with each individual camera driver and does some basic image processing. Now, the idea is that when the manager is initialised it creates two cameras and adds them to a vector so that I can access them later. The catch here is that when I create the second camera (camera2) the first camera's destructor is called for some reason, which then disconnects the camera. Normally I'd assume that the problem is somewhere in the Camera class, but in this case everything works perfectly as long as I don't create the camera2 object. What's gone wrong? CameraManager.h: #include "stdafx.h" #include <vector> #include "Camera.h" class CameraManager{ std::vector<Camera> cameras; public: CameraManager(); ~CameraManager(); void CaptureAll(); void ShowAll(); }; CameraManager.cpp: #include "stdafx.h" #include "CameraManager.h" CameraManager::CameraManager() { printf("Camera Manager: Initializing\n"); [...] Camera *camera1 = new Camera(NodeInfo,1, -44,0,0); cameras.push_back(*camera1); // Adding the following two lines causes camera1's destructor to be called. Why? Camera *camera2 = new Camera(NodeInfo,0, 44,0,0); cameras.push_back(*camera2); printf("Camera Manager: Ready\n"); }

    I have a complex map that defined typedef short short1 typedef short short2 typedef map<short1,short2> data_list; typedef map<string,list> table_list; I have a class that fill table_list class GroupingClass { table_list m_table_list; string Buildkey(OD e1){ string ostring; ostring+=string(e1.m_Date,sizeof(Date)); ostring+=string(e1.m_CT,sizeof(CT)); ostring+=string(e1.m_PT,sizeof(PT)); return ostring; } void operator() (const map<short1,short2>::value_type& myPair) { OptionsDefine e1=myPair.second; string key=Buildkey(e1); m_table_list[key][e1.m_short2]=e1.m_short2; } operator table_list() { return m_table_list; } }; and I use it by table_list TL2 GroupingClass gc; TL2=for_each(mapOD.begin(), mapOD.end(), gc); but when I try to access to internal map I have problems for example data_list tmp; tmp=TL2["AAAA"]; short i=tmp[1]; //I dont update i variable but if i use a loop by itrator this work properly why this no work at first way thanks herzl

  • Cannot pass null to server using jQuery AJAX. Value received at the server is the string "null".

    - by Tom
    I am converting a javascript/php/ajax application to use jQuery to ensure compatibility with browsers other than Firefox. I am having trouble passing true, false, and null values using jQuery's ajax function. Javascript code: $.ajax ( { url : <server_url>, dataType: 'json', type : 'POST', success : receiveAjaxMessage, data: { valueTrue : true, valueFalse : false, valueNull : null } } ); PHP code: var_dump($_POST); Server output: array(3) { ["valueTrue"]=> string(4) "true" ["valueFalse"]=> string(5) "false" ["valueNull"]=> string(4) "null" } The problem is that the null, true, and false values are being converted to strings. The Javascript AJAX code currently in use passes null, true, and false correctly but only works in Firefox. Does anyone know how to solve this problem using jQuery? Here is some working code (not using jQuery) to compare with the code not-working code given above. Javascript Code: ajaxPort.send ( <server_url>, { valueTrue : true, valueFalse : false, valueNull : null } ); PHP code: var_dump(json_decode(file_get_contents('php://input'), true)); Server output: array(3) { ["valueTrue"]=> bool(true) ["valueFalse"]=> bool(false) ["valueNull"]=> NULL } Note that the null, true, and false values are correctly received. Note also that in the second method the $_POST array is not used in the PHP code. I think this is the key to the problem, but I cannot find a way to replicate this behavior using jQuery.

  • Why ASP.NET menu control ignores roles in Web.sitemap?

    - by MainMa
    Hi, I have a website with a menu based on sitemap. ActiveDirectoryRoleProvider is a custom class. securityTrimmingEnabled of sitemap provider is set to true. Now, nevertheless the roles set in the sitemap file, site menu displays every sitemap entity. So for example if I have in sitemap a node with roles="*", a second one with roles="Administrators" and a third one with roles="Foo" and I login as a member of Administrators group but not Foo group, the site menu will display all three items. On the other hand, if I have a node which does not specify roles attribute but has children, this node will never be displayed. If I put: <%= HttpContext.Current.User.IsInRole("Administrators") ? "Admin" : "Not admin"%> <%= HttpContext.Current.User.IsInRole("Foo") ? "Foo" : "Not foo"%> before the menu, it displays that I'm Admin, but Not foo, which is just fine. So if it knows that I'm Admin but Not foo, why does it continue to display Foo's sitemap nodes? Note: changing authorizations has no effect on the menu. It continues to show every item, even for the pages I'm unable to access.

  • Passing a Batch File an Argument Containing a Quote Containing a Space

    - by Synetech inc.
    Hi, On many occasions I have dealt with passing batch files arguments with spaces, quotes, percents, and slashes and all sorts of combinations of them. Usually I managed to figure out how to accomplish what I want, but this time I am stuck. I have tried a couple of hundred combinations now and my head is starting to hurt. I’ve reduced the problem quite nicely. It’s a simple requirement: pass a double-quoted space from one batch file to another. That is, one batch file should pass some string X to another so that the the second one echos " ". I just can’t figure out what X should be. Here is a minimal batch file that demonstrates and attempt that does not work. (This BAT file takes the place of both by calling itself.) ::Goal is to print: ::" " ::That is, to pass a quoted space from a BAT file to a BAT file if not (%1)==() goto recurse %0 "" "" :recurse echo %1 pause It does not work. I’ve tried using "\" \"", """ """, """" """", "\"" "\"", ""\" \""", "^" ^"", ^"" "^", and so on. Either they print double double-quotes, lose everything after the space, or something else (that is wrong). Any ideas? Thanks.

  • DB Design to store custom fields for a table

    - by Fazal
    Hi All, this question came up based on the responses I got for the question http://stackoverflow.com/questions/2785033/getting-wierd-issue-with-to-number-function-in-oracle As everyone suggested that storing Numeric values in VARCHAR2 columns is not a good practice (which I totally agree with), I am wondering about a basic Design choice our team has made and whether there are better way to design. Problem Statement : We Have many tables where we want to give certain number of custom fields. The number of required custom fields is known, but what kind of attribute is mapped to the column is available to the user E.g. I am putting down a hypothetical scenario below Say you have a laptop which stores 50 attribute values for every laptop record. Each laptop attributes are created by the some admin who creates the laptop. A user created a laptop product lets say lap1 with attributes String, String, numeric, numeric, String Second user created laptop lap2 with attributes String,numeric,String,String,numeric Currently there data in our design gets persisted as following Laptop Table Id Name field1 field2 field3 field4 field5 1 lap1 lappy lappy 12 13 lappy 2 lap2 lappy2 13 lappy2 lapp2 12 This example kind of simulates our requirement and our design Now here if somebody is lookinup records for lap2 table doing a comparison on field2, We need to apply TO_NUMBER. select * from laptop where name='lap2' and TO_NUMBER(field2) < 15 TO_NUMBER fails in some cases when query plan decides to first apply to_number instead of the other filter. QUESTION Is this a valid design? What are the other alternative ways to solve this problem One of our team mates suggested creating tables on the fly for such cases. Is that a good idea How do popular ORM tools give custom fields or flex fields handling? I hope I was able to make sense in the question. Sorry for such a long text.. This causes us to use TO_NUMBER when queryio

  • Synchronous Android activities

    - by rayman
    Ive made mis-leading topic in my last question, so i open this new question to clear what I realy want. sorry for the inconvenience. I wanna run two system(Android) activities one after another in specific order from my main activity. now as we know, startActivity is an asynchronous operation, so i cant keep on a specific order. so i thought maybe I should try to do it with dialogBox in the middle but also running a dialogBox is an asynchronous. now as i said the activities which i try to run are Android activities, so i cant even start them with startActivityForResult (or mybe i can, but i dont get any result back to my main(calling) activity) Any tricks how could i manage with this issue? Some code: first activity: Intent intent = new Intent(); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setAction(Settings.ACTION_APPLICATION_SETTINGS); startActivity(intent); second activity: Intent intent = new Intent(Intent.ACTION_VIEW); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.setDataAndType(Uri.fromFile(tmpPackageFile .getAbsoluteFile()), "application/vnd.android.package-archive"); startActivity(intent); as you can see, i dont have any access to those activites, i can just run thire intents from my main activity.
