• How to deploy SQL Reporting 2005 when Data Sources are locked?

  - by spoulson

  The DBAs here maintain all SQL Server and SQL Reporting servers. I have a custom developed SQL Reporting 2005 project in Visual Studio that runs fine on my local SQL Database and Reporting instances. I need to deploy to a production server, so I had a folder created on a SQL Reporting 2005 server with permissions to upload files. Normally, a deploy from within Visual Studio is all that is needed to upload the report files. However, for security purposes, data sources are maintained explicitly by DBAs and stored in a separated locked down common folder on the reporting server. I had them create the data source for me. When I attempt to deploy from VS, it gives me the error "The item '/Data Sources' already exists." I get this whether I'm deploying the whole project or just a single report file. I already set OverwriteDataSources=false in the project properties. The TargetServer URL and folder are verified correct. I suppose I could copy the files manually, but I'd like to be able to deploy from within VS. What could I be doing wrong?

• Monitoring all events in a class and sub-classes

  - by Basiclife

  Hi, I wonder if someone can help me. I've got a console App which I use to debug various components as I develop them. I'd like to be able to log to the console every time an event is fired either in the object I've instantiated or in anything it's instantiated [ad infinitum]. I wouldn't see some of these events normally due to them being consumed further down the chain). Ideally I would be able to log all public and private events but if only public are possible, I can live with that. I've Googled and all I can find is how to monitor a directory - So I'm not sure if this is not possible or simply has a name that I don't know. The sort of information I'm after is similar to what's found in an exception - Target Site, Source, Stack Trace, etc... Could I perhaps do this through reflection somehow? If someone could tell me if this is even possible and perhaps point me at some good resources, I'd be very grateful. Many thanks Basic To Give you an idea of the console App: Sub Main() Container = ContainerGenerate.GenerateContainer() Dim TemplateID As New Guid("5959b961-b347-46bc-b1b6-cba311304f43") Dim Templater = Container.Resolve(Of Interfaces.Mail.IMailGenerator)() Dim MyMessage = Templater.GenerateMail(TemplateID, Nothing, Nothing) Dim MySMTPClient = Container.Resolve(Of SmtpClient)() MySMTPClient.Send(MyMessage) Finish() End Sub

• Monitor web sites visited using Internet Explorer, Opera, Chrome, Firefox and Safari in Python

  - by Zachary Brown

  I am working on a project for work and have seemed to run into a small problem. The project is a similar program to Web Nanny, but branded to my client's company. It will have features such as website blocking by URL, keyword and web activity logs. I would also need it to be able to "pause" downloads until an acceptable username and password is entered. I found a script to monitor the URL visited in Internet Explorer (shown below), but it seems to slow the browser down considerably. I have not found any support or ideas onhow to implement this in other browsers. So, my questions are: 1). How to I monitor other browser activity / visited URLs? 2). How do I prevent downloading unless an acceptable username and password is entered? from win32com.client import Dispatch,WithEvents import time,threading,pythoncom,sys stopEvent=threading.Event() class EventSink(object): def OnNavigateComplete2(self,*args): print "complete",args stopEvent.set() def waitUntilReady(ie): if ie.ReadyState!=4: while 1: print "waiting" pythoncom.PumpWaitingMessages() stopEvent.wait(.2) if stopEvent.isSet() or ie.ReadyState==4: stopEvent.clear() break; time.clock() ie=Dispatch('InternetExplorer.Application',EventSink) ev=WithEvents(ie,EventSink) ie.Visible=1 ie.Navigate("http://www.google.com") waitUntilReady(ie) print "location",ie.LocationName ie.Navigate("http://www.aol.com") waitUntilReady(ie) print "location",ie.LocationName print ie.LocationName,time.clock() print ie.ReadyState

• JQuery Selector - Finding an img in a table

  - by CccTrash

  Cant seem to get the following to find the 'skull' button when the 'heart' button is clicked... Here is the JQuery... $(".voteup").click(function() { var id = $(this).attr("title"); var userID = $('[id$=HiddenFieldUserID]').val(); var ipAddress = $('[id$=HiddenFieldIPAddress]').val(); var skullButton = $(this).parent().siblings(".votedowntd").children("votedown"); registerUpVote("up", id, $(this), skullButton, userID, ipAddress); }); And the HTML... <table width="200px"> <td width="35px" class="votedowntd"> <img src='<%# (bool)Eval("skull") ? "images/skull.png" : "images/skull-bw.png" %>' alt="Vote Down" class="votedown" title='<%# Eval("entry.ID") %>' /> </td> <td width="130px" style="text-align: center;"> Num Votes Goes Here </td> <td width="35px" class="voteuptd"> <img src='<%# (bool)Eval("heart") ? "images/heart.png" : "images/heart-bw.png" %>' alt="Vote Up" class="voteup" title='<%# Eval("entry.ID") %>' /> </td> <tr> </tr> </table> So basically what I need to do is when one img is clicked, I need to find the other one. Why is what I have not working? Is there a better way to do this?

• Issue Implementing Colorbox Correctly in IE (all versions)

  - by Andrew

  I've been pulling my hair out (and going way over allotted hours) to try and figure out why Colorbox isn't working properly on the following page: http://www.fiberforge.com I've set up a Colorbox test link on the very bottom right that says "Web Design By All Web Cafe", which should open up a small logo image. In Firefox, Safari, etc the modal behaves as it should, opening center center above all of the existing on-page content. In IE, not only is the modal not centered, but it appears as though it's not obeying absolute positioning and pushing all of the existing on-page content down below. Add to that the fact that it's not opening to the correct size and creating scrollbars next to the modal image, and we have ourselves one ugly modal. The scrollbars I can live with (by just resizing the min-height of the modal), but I can't figure out why it won't center. Let me say that I did not code this site initially and it was completed quite a few years ago, so there are quite probably numerous CSS hacks to get things to display properly, any number of which may be causing this problem. By contrast, Thickbox is also set up on this site (if you click on the "Play Video" callout in the dark blue area) and behaves correctly, though suffers from some weird sizing/padding issues, hence the desire to replace it with something a bit more modern and extensible. I can verify that there is no conflict having both of these modal scripts/CSS files concurrently as the problem still occurs with Colorbox even when Thickbox is removed entirely. Any thoughts or suggestions would be greatly appreciated.

• running .net application over a network

  - by Marlon

  Hello, I need some advice please. I need to enable a .Net application to run over a network share, the problem is that this will be on clients network shares and so the path will not be identical. I've had a quick look at ClickOnce and the publish options in VS2008 but it wants a specific network share location - and I'm assuming this location gets stored somewhere when it does its thing. At the moment the job is being done with a old VB6 application and so gets around all these security issues, but that application is poorly written and almost impossible to maintain so it really needs to go. Is it possible for the domain controller to be set up to allow this specific .Net application to execute? Any other options would be welcomed as I want to get this little application is very business critical. I aught to say that the client networks are schools, and thus are often quite locked down as are the client machines, so manually adding exceptions to each client machine is a big no no. Marlon --Edit-- Apologies, I forgot to mention we're restricted to .net 2.0 for the moment, we are planning to upgrade this to 4.0 but that won't be immediate.

• How can I setup Hudson to use the same repository for different projects and maintain separate chang

  - by Allen

  I typically setup SVN to host 1 big project per repository but a lot of our infrastructure has changed and we now have one main SVN server that has a hierarchy like so Branches Tags Trunk Project1 files & folders Project2 files & folders Project3 files & folders Projects1,2, and 3 do not share anything amongst themselves, they are independent projects each with their own solution file to be built. I can setup projects in Hudson like so Repository Url: http://server/svn/MainRepository Local module directory (optional): /Trunk/Project1 And that will maintain a separate workspace for each project, but every time you commit to Project 2 or Project 3, a build gets kicked off in Hudson for every project based in that repository. Also, any commit made anywhere in the repository is pulled down and inserted into the Hudson changelog for all of them. I know the easiest solution would be to simply separate every project into its own repository. However, if I couldn't do that due to various reasons, is there a feasible way to achieve the functionality that having separate repositories gets me? I want commits to the sub folder of project 1 to only affect project 1. No other project's commits should cause project 1 to build and project 1's changelog in Hudson should only have commit notes from project 1.

• Excel VBA Macro for Pivot Table with Dynamic Data Range

  - by John Ziebro

  CODE IS WORKING! THANKS FOR THE HELP! I am attempting to create a dynamic pivot table that will work on data that varies in the number of rows. Currently, I have 28,300 rows, but this may change daily. Example of data format as follows: Case Number Branch Driver 1342 NYC Bob 4532 PHL Jim 7391 CIN John 8251 SAN John 7211 SAN Mary 9121 CLE John 7424 CIN John Example of finished table: Driver NYC PHL CIN SAN CLE Bob 1 0 0 0 0 Jim 0 1 0 0 0 John 0 0 2 1 1 Mary 0 0 0 1 0 Code as follows: Sub CreateSummaryReportUsingPivot() ' Use a Pivot Table to create a static summary report ' with model going down the rows and regions across Dim WSD As Worksheet Dim PTCache As PivotCache Dim PT As PivotTable Dim PRange As Range Dim FinalRow As Long Dim FinalCol As Long Set WSD = Worksheets("PivotTable") 'Name active worksheet as "PivotTable" ActiveSheet.Name = "PivotTable" ' Delete any prior pivot tables For Each PT In WSD.PivotTables PT.TableRange2.Clear Next PT ' Define input area and set up a Pivot Cache FinalRow = WSD.Cells(Application.Rows.Count, 1).End(xlUp).Row FinalCol = WSD.Cells(1, Application.Columns.Count). _ End(xlToLeft).Column Set PRange = WSD.Cells(1, 1).Resize(FinalRow, FinalCol) Set PTCache = ActiveWorkbook.PivotCaches.Add(SourceType:= _ xlDatabase, SourceData:=PRange) ' Create the Pivot Table from the Pivot Cache Set PT = PTCache.CreatePivotTable(TableDestination:=WSD. _ Cells(2, FinalCol + 2), TableName:="PivotTable1") ' Turn off updating while building the table PT.ManualUpdate = True ' Set up the row fields PT.AddFields RowFields:="Driver", ColumnFields:="Branch" ' Set up the data fields With PT.PivotFields("Case Number") .Orientation = xlDataField .Function = xlCount .Position = 1 End With With PT .ColumnGrand = False .RowGrand = False .NullString = "0" End With ' Calc the pivot table PT.ManualUpdate = False PT.ManualUpdate = True End Sub

• Increasing Regex Efficiency

  - by cam

  I have about 100k Outlook mail items that have about 500-600 chars per Body. I have a list of 580 keywords that must search through each body, then append the words at the bottom. I believe I've increased the efficiency of the majority of the function, but it still takes a lot of time. Even for 100 emails it takes about 4 seconds. I run two functions for each keyword list (290 keywords each list). public List<string> Keyword_Search(HtmlNode nSearch) { var wordFound = new List<string>(); foreach (string currWord in _keywordList) { bool isMatch = Regex.IsMatch(nSearch.InnerHtml, "\\b" + @currWord + "\\b", RegexOptions.IgnoreCase); if (isMatch) { wordFound.Add(currWord); } } return wordFound; } Is there anyway I can increase the efficiency of this function? The other thing that might be slowing it down is that I use HTML Agility Pack to navigate through some nodes and pull out the body (nSearch.InnerHtml). The _keywordList is a List item, and not an array.

• What's wrong with debugging in Eclipse on Android?

  - by Sebastian Dwornik

  I've obviously been spoiled by Visual Studio, because although I'm just learning Android and the Eclipse environment, debugging apps in Eclipse is becoming a serious detriment to further development. For example, Eclipse will compile this divide by zero just fine: public class Lesson2Main extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate (savedInstanceState); int i = 1 / 0; TextView tv = new TextView (this); tv.setText ("Hello, Android!"); setContentView (tv); } } And then, when it executes it under the debugger, I will get a full screen of useless debug info, non of which actually points me to the specific line containing the error. The stackTrace is null within the exception ('e') info tree, and it simply states a message stating 'ArithmeticException'. (that's nice, how about you point me in the direction of where you found it!?) I've looked all over the screen and am baffled that this IDE can't get this right. Does developing with Eclipse resort everyone back to 1991 with printf() like logging at every interval then to track down bugs? Seriously. Is there a configuration or plug-in that I'm missing to help with this? I haven't tested this case with XCode, but if the iPhone dev. IDE handles this more like Visual Studio, then no wonder the Android marketplace has so few apps. I'm excited about Android, but it seems that Eclipse is getting in the way.

• How to restrain one's self from the overwhelming urge to rewrite everything?

  - by Scott Saad

  Setup Have you ever had the experience of going into a piece of code to make a seemingly simple change and then realizing that you've just stepped into a wasteland that deserves some serious attention? This usually gets followed up with an official FREAK OUT moment, where the overwhelming feeling of rewriting everything in sight starts to creep up. It's important to note that this bad code does not necessarily come from others as it may indeed be something we've written or contributed to in the past. Problem It's obvious that there is some serious code rot, horrible architecture, etc. that needs to be dealt with. The real problem, as it relates to this question, is that it's not the right time to rewrite the code. There could be many reasons for this: Currently in the middle of a release cycle, therefore any changes should be minimal. It's 2:00 AM in the morning, and the brain is starting to shut down. It could have seemingly adverse affects on the schedule. The rabbit hole could go much deeper than our eyes are able to see at this time. etc... Question So how should we balance the duty of continuously improving the code, while also being a responsible developer? How do we refrain from contributing to the broken window theory, while also being aware of actions and the potential recklessness they may cause? Update Great answers! For the most part, there seems to be two schools of thought: Don't resist the urge as it's a good one to have. Don't give in to the temptation as it will burn you to the ground. It would be interesting to know if more people feel any balance exists.

• How to terminate a particular Azure worker role instance

  - by Oliver Bock

  Background I am trying to work out the best structure for an Azure application. Each of my worker roles will spin up multiple long-running jobs. Over time I can transfer jobs from one instance to another by switching them to a readonly mode on the source instance, spinning them up on the target instance, and then spinning the original down on the source instance. If I have too many jobs then I can tell Azure to spin up extra role instance, and use them for new jobs. Conversely if my load drops (e.g. during the night) then I can consolidate outstanding jobs to a few machines and tell Azure to give me fewer instances. The trouble is that (as I understand it) Azure provides no mechanism to allow me to decide which instance to stop. Thus I cannot know which servers to consolidate onto, and some of my jobs will die when their instance stops, causing delays for users while I restart those jobs on surviving instances. Idea 1: I decide which instance to stop, and return from its Run(). I then tell Azure to reduce my instance count by one, and hope it concludes that the broken instance is a good candidate. Has anyone tried anything like this? Idea 2: I predefine a whole bunch of different worker roles, with identical contents. I can individually stop and start them by switching their instance count from zero to one, and back again. I think this idea would work, but I don't like it because it seems to go against the natural Azure way of doing things, and because it involves me in a lot of extra bookkeeping to manage the extra worker roles. Idea 3: Live with it. Any better ideas?

• desing pattern for related inputs

  - by curiousMo

  My question is a design question : let's say i have a data entry web page with 4 drop down lists, each depending on the previous one, and a bunch of text boxes. country (ddl), state (ddl), city (ddl), boro (ddl), address (txtBox), zipcode(txtbox). and an object that represents a datarow with a value for each. naturally the country, state, city and boro values will be values of primary keys of some lookup tables. when the user chooses to edits that record, i would load it from database and load it into the page. the issue that I have is how to streamline loading the ddls. i have some code that would grab the object, look thru its values and move them to their corresponding input controls in one shot. but in this case i will have to load possible values of country, then assign values, then load values of state, then assign value ans so on. I guess i am looking for an elegant solution. i am using asp.net, but i think it is irrelevant to the question. i am looking more into a design pattern. thanks

• how to do these in visio 2007?

  - by user285825

  I am very annoyed with this software. I am unable to do many things with this software. In the book 'UML distilled' many features of UML are discussed which I am not sure how to accomplish with visio 2007. For instance, 1) I can't find the unary association. In the UML static structure under shapes panel on left, there are a lot of components like package, class, blah, blah, binary association, blah, blah, association class. But where is unary association. 2) For sequence diagram, I created a message (any of sync, async, call type message, ordinary message). The I tried to incorporate some parameter information. I went to the properties. There were a category called arguments. But selecting that shows a table where arguments are supposed to be shown. But all are diasbled. 3) For sequence diagram, there is no component delete (the big X) in the UML Sequence. 4) For class diagram, there is supposed to be a comment compartment where comments like mentioning the responsibilities are allowed using a comment prefixed with "--". But I am not sure how to accomplish them. 5) there is also supposed to be a way to indicate static properties of a class. But I am not sure how to do that in visio. 6) there is supposed to be a stereotype for class <. But in the stereotype drop down there is no stereotype. 7) where is the ball and socket component?

• Old desktop programmer wants to create S+S project

  - by Craig

  I have an idea for a product that I want to be web-based. But because I live in Brasil, the internet is not always available so there needs to be a desktop component that is available for when the internet is down. Also, I have been a SQL programmer, a desktop application programmer using dBase, VB and Pascal, and I have created simple websites using HTML and website creation tools, such as Frontpage. So from my research, I think I have the following options; PHP, Ruby on Rails, Python or .NET for the programming side. MySQL for the DB. And Apache, or possibly IIS, for the webserver. I will probably start with a local ISP provider for the cloud servce. But then maybe move to something more "robust" and universal in the future, ie. Amazon, or Azure, or something along that line. My question then is this. What would you recommend for something like this? I'm sure that I have not listed all of the possibilities, but the ones I have researched and thought of. Thanks everyone, Craig

• What's next for all of these Microsoft "overlapping" and "enhanced" products ?

  - by pointlesspolitics

  Recently I attended a road show, organised by MS Gold Partner company in the UK. The products discussed were: SharePoint server (2010 and 2007), Exchange server, Office Communication Server 2007, Exchange hosted services Office Live meeting, Office Communicator, System Center Configuration Manager and Operation Manager, VMware, Windows 7 etc. As Microsoft claims the enhancement in the each product against higher version, I felt that clients are not much interested in all these details. For example Office Communicator, surely they have improved a lot the product and first site all said 'WOW' great product, but nobody wish to pay money for all these extra features. Some argued, they are bogged down by all these increased number of menus. They don't need soft call feature included with mobile call. It apply for all other products as well such as MS office (next what 2 ribbons ?), windows OS and many more. Indeed there must be good features in all these products, but is it worth to spend money and time to update the older system ? Also sometimes these feature will decrease the productivity instead increase it. *So do you think what ever enhancement MS is doing in the products is only for selling purpose, not a real use ?? and I think also keep the developer busy learning the new tools and features. * I am sure some some people here will argue that some people need this sort of features. But I am not talking about NASA or MI5 guys. I am talking of usual businesses and joe public. Any ideas welcome.

• Fast Lightweight Image Comparisson Metric Algorithm

  - by gav

  Hi All, I am developing an application for the Android platform which contains 1000+ image filters that have been 'evolved'. When a user selects a photo I want to present the most relevant filters first. This 'relevance' should be dependent on previous use cases. I have already developed tools that register when a filtered image is saved; this combination of filter and image can be seen as the training data for my system. The issue is that the comparison must occur between selecting an image and the next screen coming up. From a UI point of view I need the whole process to take less that 4 seconds; select an image- obtain a metric to use for similarity - check against use cases - return 6 closest matches. I figure with 4 seconds I can use animations and progress dialogs to keep the user happy. Due to platform contraints I am fairly limited in the computational expense of the algorithm. I have implemented a technique adapted from various online tutorials for running C code on the G1 and hence this language is available Specific Constraints; Qualcomm® MSM7201A™, 528 MHz Processor 320 x 480 Pixel bitmap in 32 bit ARGB ~ 2 seconds computational time for the native method to get the metric ~ 2 seconds to compare the metric of the current image with training data This is an academic project so all ideas are welcome, anything you can think of or have heard about would be of interest to me. My ideas; I want to keep the complexity down (O(n*m)?) by using pixel data only rather than a neighbourhood function I was looking at using the Colour historgram/Greyscale histogram/Texture/Entropy of the image, combining them to make the measure. There will be an obvious loss of information but I need the resultant metric to be substantially smaller than the memory footprint of the image (~0.512 MB) As I said, any ideas to direct my research would be fantastic. Kind regards, Gavin

• Why are changes to coffeescript files not being compiled when my Rails 3.2.0 app is in development mode?

  - by ben

  Normally, any changes I make to .js.coffee files in my Rails 3.2.0 app in development mode take effect when I refresh the page. All of a sudden, this is not happening. If I do rake assets:precompile, then the changes are shown, but then if I do rake assets:clean they go back to not being shown. What is causing this? Edit: Restarting the server makes the changes show. Why isn't this happening automatically as before? Edit: Here is my development.rb Myapp::Application.configure do # Settings specified here will take precedence over those in config/application.rb # In the development environment your application's code is reloaded on # every request.

• PayPal integration woes: PDT hangs on return to site

  - by Tom

  Hi, I'm implementing PayPal IPN & PDT. After some headache & time at the sandbox, IPN is working well and PDT returns the correct $_GET data. The implementation is as follows: Pass user ID in form to PayPal User buys product and triggers IPN which updates database for given user ID PDT returns transaction ID when user returns to site The return page says "please wait" and repeat-Ajax-checks for the transaction status User is redirected to success/failure page Everything works well, EXCEPT that when using the PayPal ready PHP code for PDT to do a return POST, the page hangs. PayPal waits for a response and the user never gets back to my site. I'm not getting a fail status, just nothing. The funny thing is that once the unknown error occurs, my test domain becomes unresponsive for a short period. The code (PHP): https://www.paypal.com/us/cgi-bin/webscr?cmd=p/xcl/rec/pdt-code-outside If I comment out the POST back, it all works fine. I'm able to pin down the problem to once the code enters the while{} loop. Unfortunately, I'm not experienced enough to write a replacement from scratch for the PayPal code, so would really appreciate any ideas on what might be wrong. The POST back goes to ssl://www.sandbox.paypal.com, and I'm using button code and an authorisation token that have all been created via a sandbox test account. Thanks in advance.

• MSTest on x64 C++/CLI

  - by Oyvind

  I got a problem using MSTest on x64: The test project depends on a couple of C++/CLI assemblies, and fails to load for some reason. In Visual Studio, I get (stripped down): Error loading D:\xxx\Xxx.Test.dll: Unable to load the test container 'D:\xxx\Xxx.Test.dll' or one of its dependencies. Error details: System.BadImageFormatException: Could not load file or assembly 'Common.Geometry.Native, Version=1.1.4574.22395, Culture=neutral, PublicKeyToken=null' or one of its dependencies. An attempt was made to load a program with an incorrect format. Running MSTest manually in a command prompt, I get: Unable to load the test container 'D:\xxx\Xxx.Test.dll' or one of its dependencies. Error details: System.IO.FileNotFoundException: Could not load file or assembly 'Common.Geometry.Native, Version=1.1.4574.22395, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified. Details worth mentioning: The test project itself is compiled using 'Any Cpu'. I use a x64 specific testrunconfig Dependency walker shows no missing native dependencies in the C++/CLI assembly (Common.Geometry.Native) Even more interesting, there is another test project in the same solution using the same C++/CLI assembly (Common.Geometry.Native), and it runs without any problems. I have also verified that there are no 32bit assemblies/dlls interfering. Any suggestions is welcome !

• Slow retrieval of data in SQLITE takes a long using ContentProvider

  - by Arlyn

  I have an application in Android (running 4.0.3) that stores a lot of data in Table A. Table A resides in SQLite Database. I am using a ContentProvider as an abstraction layer above the database. Lots of data here means almost 80,000 records per month. Table A is structured like this: String SQL_CREATE_TABLE = "CREATE TABLE IF NOT EXISTS " + TABLE_A + " ( " + COLUMN_ID + " INTEGER PRIMARY KEY NOT NULL" + "," + COLUMN_GROUPNO + " INTEGER NOT NULL DEFAULT(0)" + "," + COLUMN_TIMESTAMP + " DATETIME UNIQUE NOT NULL" + "," + COLUMN_TAG + " TEXT" + "," + COLUMN_VALUE + " REAL NOT NULL" + "," + COLUMN_DEVICEID + " TEXT NOT NULL" + "," + COLUMN_NEW + " NUMERIC NOT NULL DEFAULT(1)" + " )"; Here is the index statement: String SQL_CREATE_INDEX_TIMESTAMP = "CREATE INDEX IF NOT EXISTS " + TABLE_A + "_" + COLUMN_TIMESTAMP + " ON " + TABLE_A + " (" + COLUMN_TIMESTAMP + ") "; I have defined the columns as well as the table name as String Constants. I am already experiencing significant slow down when retrieving this data from Table A. The problem is that when I retrieve data from this table, I first put it in an ArrayList and then I display it. Obviously, this is possibly the wrong way of doing things. I am trying to find a better way to approach this problem using a ContentProvider. But this is not the problem that bothers me. The problem is for some reason, it takes a lot longer to retrieve data from other tables which have only upto 12 records maximum. I see this delay increase as the number of records in Table A increase. This does not make any sense. I can understand the delay if I retrieve data from Table A, but why the delay in retrieving data from other tables. To clarify, I do not experience this delay if Table A is empty or has less than 3000 records. What could be the problem?

• Rails: link_to_remote prototype helper with :with option

  - by Syed Aslam

  I am trying to grab the current value of a drop down list with Prototype and passing it along using :with like this <%= link_to_remote "today", :update => "choices", :url => { :action => "check_availability" } , :with => "'practitioner='+$F('practitioner')&'clinic='+$F('clinic')&'when=today'", :loading => "spinner.show(); $('submit').disable();", :complete => "spinner.hide(); $('submit').enable();" %> However, this is not working as expected. I am unable to access parameters in the controller as the link_to_remote helper is sending parameters like this: Parameters: {"succ"=>"function () {\n return this + 1;\n}", "action"=>"check_availability", "round"=>"function () {\n return __method.apply(null, [this].concat($A(arguments)));\n}", "ceil"=>"function () {\n return __method.apply(null, [this].concat($A(arguments)));\n}", "floor"=>"function () {\n return __method.apply(null, [this].concat($A(arguments)));\n}", "times"=>"function (iterator, context) {\n $R(0, this, true).each(iterator, context);\n return this;\n}", "toPaddedString"=>"function (length, radix) {\n var string = this.toString(radix || 10);\n return \"0\".times(length - string.length) + string;\n}", "toColorPart"=>"function () {\n return this.toPaddedString(2, 16);\n}", "abs"=>"function () {\n return __method.apply(null, [this].concat($A(arguments)));\n}", "controller"=>"main"} Where am I going wrong? Is there a better way to do this?
