• DDMS plugin not loading GPX files

  - by Craig

  I am unable to load a GPX file in the DDMS eclipse plugin. When specifying a GPX file, no points are added to the emulator control list. I have tried adding KML files as well, generated in Google earth. Is there a way to get these files to work? The content of the file is listed below: <?xml version="1.0" encoding="UTF-8"?> <gpx version="1.0" creator="RunKeeper - http://www.runkeeper.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.topografix.com/GPX/1/0" xsi:schemaLocation="http://www.topografix.com/GPX/1/0 http://www.topografix.com/GPX/1/0/gpx.xsd"> <trk> <name>Running 11/30/09 3:37 pm11/30/09 3:37 pm</name> <time>2009-11-30T15:37:08Z</time> <trkseg> <trkpt lat="41.811406000" lon="-72.521427000"> <ele>37.000000</ele> <time>2009-11-30T15:37:08Z</time> </trkpt> <trkpt lat="41.811030000" lon="-72.522882000"> <ele>38.000000</ele> <time>2009-11-30T15:37:10Z</time> </trkpt>

• NHibernate with nothing but stored procedures

  - by ChrisB2010

  I'd like to have NHibernate call a stored procedure when ISession.Get is called to fetch an entity by its key instead of using dynamic SQL. We have been using NHibernate and allowing it to generate our SQL for queries and inserts/updates/deletes, but now may have to deploy our application to an environment that requires us to use stored procedures for all database access. We can use sql-insert, sql-update, and sql-delete in our .hbm.xml mapping files for inserts/updates/deletes. Our hql and criteria queries will have to be replaced with stored procedure calls. However, I have not figured out how to force NHibernate to use a custom stored procedure to fetch an entity by its key. I still want to be able to call ISession.Get, as in: using (ISession session = MySessionFactory.OpenSession()) { return session.Get<Customer>(customerId); } and also lazy load objects, but I want NHibernate to call my "GetCustomerById" stored procedure instead of generating the dynamic SQL. Can this be done? Perhaps NHibernate is no longer a fit given this new environment we must support.

• "Decompile" Javascript function? *ADVANCED*

  - by caesar2k

  [1] Ok, I don't even know how to call this, to be honest. So let me get some semi-pseudo code, to show what I'm trying to do. I'm using jquery to get an already existing script declared inside the page, inside a createDocument() element, from an AJAX call. GM_xmlhttprequest({ ... load:function(r){ var doc = document_from_string(r.responseText); script_content = $('body script:regex(html, local_xw_sig)', doc).html(); var scriptEl = document.createElement('script'); scriptEl.type = 'text/javascript'; scriptEl.innerHTML = script_content; // good till here (function(sc){ eval(sc.innerHTML); // not exactly like this, but you get the idea, errors alert('wont get here ' + local_xw_sig); // local_xw_sig is a global "var" inside the source })(scriptEl); } }); so far so good, the script indeed contains the source from the entire script block. Now, inside this "script_content", there are auto executing functions, like $(document).ready(function(){...}) that, everything I "eval" the innerHTML, it executes this code, halting my encapsulated script. like variables that doesn't exist, etc removing certain parts of the script using regex isn't really an option... what I really wanted is to "walk" inside the function. like do a (completely fictional): script = eval("function(){" + script_content + "};"); alert(script['local_xw_sig']); // a03ucc34095cw3495 is there any way to 'disassemble' the function, and be able to reach the "var"s inside of it? like this function: function hello(){ var message = "hello"; } alert(hello.message); // message = var inside the function is it possible at all? or I will have to hack my way using regex? ;P [2] also, is there any way I can access javascript inside a document created with "createDocument"?

• Problem: Sorting for GridView/ObjectDataSource changes depending on page

  - by user148298

  I have a GridView tied to an ObjectDataSource using paging. The paging works fine, except that the sort order changes depending on which page of the results is being viewed. This causes items to reappear on subsequent pages among other issues. I traced the problem to my DAL, which reads a page at a time and then sorts it. Obviously the sorting is going to change as the result set size changes. Is there an improvement to this algorithm. I would like to use a datareader if possible: [System.ComponentModel.DataObjectMethod(System.ComponentModel.DataObjectMethodType.Select)] public static WordsCollection LoadForCriteria(string sqlCriteria, int maximumRows, int startRowIndex, string sortExpression) { //DEFAULT SORT EXPRESSION if (string.IsNullOrEmpty(sortExpression)) sortExpression = "OrderBy"; //CREATE THE DYNAMIC SQL TO LOAD OBJECT StringBuilder selectQuery = new StringBuilder(); selectQuery.Append("SELECT"); if (maximumRows > 0) selectQuery.Append(" TOP " + (startRowIndex + maximumRows).ToString()); selectQuery.Append(" " + Words.GetColumnNames(string.Empty)); selectQuery.Append(" FROM sw_Words"); string whereClause = string.IsNullOrEmpty(sqlCriteria) ? string.Empty : " WHERE " + sqlCriteria; selectQuery.Append(whereClause); selectQuery.Append(" ORDER BY " + sortExpression); Database database = Token.Instance.Database; DbCommand selectCommand = database.GetSqlStringCommand(selectQuery.ToString()); //EXECUTE THE COMMAND WordsCollection results = new WordsCollection(); int thisIndex = 0; int rowCount = 0; using (IDataReader dr = database.ExecuteReader(selectCommand)) { while (dr.Read() && ((maximumRows < 1) || (rowCount < maximumRows))) { if (thisIndex >= startRowIndex) { Words varWords = new Words(); Words.LoadDataReader(varWords, dr); results.Add(varWords); rowCount++; } thisIndex++; } dr.Close(); } return results; }

• Dynamically add User Controls to a Silverlight 4 page

  - by PilotBob

  I am building an iGoogle like "dashboard" for our application with silverlight 4. Each users dashboard (which snapins and their positions) will be stored in the database. Each snap in is a user control, for example... AwesomeSnapin.xaml. On the dashboard page in silverlight I am retrieving the users dashboard which is a collection of snapin objects which include the information on the snapin. I can store the name of the page or the class or whatever is needed. I have the following code which loops through the collection of snapins to add them to the dashboard page. In testing I have just hard coded a single snapin item. Here is the prototype code: foreach (var UserSnapin in op.Entities) { UserControl uc = new AmsiSL.eFinancials.BudgetCheck(); Canvas.SetLeft(uc, UserSnapin.PositionLeft); Canvas.SetTop(uc, UserSnapin.PositionTop); Layout.Children.Add(uc); MessageBox.Show(String.Format("Added {0}",UserSnapin.Snapin.Name)); } The above works fine... but of course adds the BudgetCheck snapin for every item that is defined for the users dashboard. Of course the messagebox is for debugging purposes only. How would I change line 3 of that to load the user control class (using classname or xaml path whichever is better) based on the data in the collection.

• Doing large updates against indexed view

  - by user217136

  We have an indexed view that runs across three large tables. Two of these tables (A & B) are constantly getting updated with user transactions and the other table (C) contains data product info that is needs to be updated once a week. This product table contains over 6 million records. We need this view across these three tables for our core business process and unfortunately we cannot change this aspect. We even had a sql server MVP come in to help test under load to make sure we have the most efficient configuration. There is one column in the product table that gets utilized in the view and has to be updated each week. The problem we are now encountering is that as volume is increasing on our transactions against tables A & B, the update to Table C is causing deadlocks. I have tried several different methods to no avail: 1) I was hoping that we could change the view so that table C could be a dirty read "WITH (NOLOCK)" but apparently that functionality is not available with indexes views. 2) I thought about updating a new column in Table C and then just renaming it when the process is done but you cannot do that due to the dependency in the view. 3) I also entertained the idea of writing this value to a temporary product table, and then running an ALTER statement against the view to have it point to my new table. however when i did that the indexes on my view were dropped and it took quite a bit of time to recreate them. 4) we tried to do the weekly update in small chunks (as small as 100 records at a time) but we still run into dead locks. questions: a) we are using sql server 2005. Does sql server 2008 have a new functionality with their indexed views that would help us? Is there now a way to do dirty reads w/ an indexed view? b) a better approach to altering an existing view to point to a new table? thanks!

• jasper Chart can't be displayed using tomcat

  - by Aru

  Hi, I am using jasperreports-3.5.0 to generate timeSeries chart. When I run it through eclipse it is working fine. But if I create .war file of project and run through tomcat by deploying the project into tomcat / webapps folder then chart can not be displayed. What could be the problem? code: PrintWriter out = response.getWriter(); response.setContentType("text/html"); JRDataSource dataSource = createReportDataSource(perfArrayListSample.toArray()); InputStream input = getServletConfig().getServletContext().getResourceAsStream("/CpuUsage.jrxml"); JasperDesign design = JRXmlLoader.load(input); JasperReport report = JasperCompileManager.compileReport(design); JasperPrint print = JasperFillManager.fillReport(report, new HashMap(), dataSource); JRHtmlExporter exporter = new JRHtmlExporter(); request.getSession().setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, print); exporter.setParameter(JRExporterParameter.JASPER_PRINT, print); exporter.setParameter(JRExporterParameter.OUTPUT_WRITER, out); exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "image?ver="+new Date().getTime() +"&image="); exporter.exportReport(); perfArrayListSample.clear();

• Requiring library consumers reference additional assembly when using certain types

  - by Thomas G. Mayfield

  I have library code that uses ICSharpCode.SharpZipLib under the hood to make it easy to use ZIP files as data sources when running integration tests. As it stands, if I reference my library from another project, the other project will compile just fine, but when it accesses the code that uses SharpZipLib, I get an exception for it not finding the zip library: failed: System.IO.FileNotFoundException : Could not load file or assembly 'ICSharpCode.SharpZipLib, Version=0.85.5.452, Culture=neutral, PublicKeyToken=1b03e6acf1164f73' or one of its dependencies. The system cannot find the file specified. If the types in my library derived from a class in SharpZipLib, it'd generate a compile error CS0012. What other ways are there for triggering a CS0012, so that using code that requires SharpZipLib (but doesn't clearly indicate it) would cause consumer code to fail compilation? I've had similar problems in the past when I've used libraries like DeftTech.DuckTyping under the hood. I'd add my library code to a new project, start working, compile, run, and then suddenly hit an edge case that I'd used duck typing to get around and get a runtime error. What I'd most like is to have the same behavior as if I'd derived from a type in the 3rd-party library, so that a reference to my derived type generates a CS0012: The type 'type' is defined in an assembly that is not referenced. You must add a reference to assembly 'assembly'.

• Django Template tag, generating template block tag

  - by Issy

  Hi Guys, Currently a bit stuck, wondering if anyone can assist. I am using django-adminfiles. Which is a near little application. I want to use it to insert images into posts/articles/pages for a site i am building. How django-adminfiles works is it inserts a placeholder i.e <<< ImageFile and this gets rendered using a django template. It also has the feature of inserting custom options i.e (Insert Medium Image) , i figured i would used this to automatically resize images and include it in the post (similar to how WP does it). Django-adminfiles makes use of sorl.thumbnail app to generate thumbnails. So i have tried testing generating thumbnails: The current template that is used to render the inserted image is: {% spaceless %} <img src="{{ upload.upload.url }}" width="{{ upload.width }}" height="{{ upload.height }}" class="{{ options.class }}" class="{{ options.size }}" alt="{% if options.alt %}{{ options.alt }}{% else %}{{ upload.title }}{% endif %}" /> {% endspaceless %} I tried modifying this to: {% load thumbnail %} {% spaceless %} <img src="{% thumbnail upload.upload.url 200x50 %}" width="{{ upload.width }}" height="{{ upload.height }}" class="{{ options.class }}" class="{{ options.size }}" alt="{% if options.alt %}{{ options.alt }}{% else %}{{ upload.title }}{% endif %}" /> {% endspaceless %} I get the error: Exception Value: Caught an exception while rendering: Source file: '/media/uploads/DSC_0014.jpg' does not exist. I figured the thumbnail needs the absolute path so tried putting that in the template, and that works. i.e this works: {% thumbnail '/Users/me/media/uploads/DSC_0014.jpg' 200x50 %} So basically i need to generate the absolute path to the file give the relative path (to web root). You could do this by passing the MEDIA_ROOT setting to the template, but the reason i want to do a template tag is to programmatically set the image size.

• Adding a dynamic image to UITable View Cell

  - by Graeme

  Hi, I have a table in which I want a dynamic image to load in at the left-hand side. The table needs to use an IF statement to select the appropriate image from the "Resources" folder, and needs to be based upon [dog types]. The [dog types] is extracted from an RSS feed, and so the image in the table cell needs to match the each cell's [dog types] tag. Update: See code below for what I'm looking to do (only below it's for earthquakes, for me its pictures of dogs). I suspect I need to use - (UIImage *)imageForTypes:(NSString *)types { to do such a thing. Thanks. Updated code: This is for Apple's Earthquake sample but does exactly what I need to do. It matches images to the severity (2.0, 3.0, 4.0, 5.0 etc.) of every earthquake to the magnitude. - (UIImage *)imageForMagnitude:(CGFloat)magnitude { if (magnitude >= 5.0) { return [UIImage imageNamed:@"5.0.png"]; } if (magnitude >= 4.0) { return [UIImage imageNamed:@"4.0.png"]; } if (magnitude >= 3.0) { return [UIImage imageNamed:@"3.0.png"]; } if (magnitude >= 2.0) { return [UIImage imageNamed:@"2.0.png"]; } return nil; } and under - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath magnitudeImage.image = [self imageForMagnitude:earthquake.magnitude];

• ASP.NET MVC.NET JQueryUI datepicker inside a div loaded/updated with ajax.actionlink

  - by ArjanW

  Im trying to incorporate jqueryUI's datepicker inside a partialview like this: <% using (Ajax.BeginForm("/EditData", new AjaxOptions { HttpMethod = "POST", UpdateTargetId = "div1" })) {%> Date: <%= Html.TextBox("date", String.Format("{0:g}", Model.date), new { id = "datePicker"})%> <% } %> <script type="text/javascript"> $(function() { $("#datePicker").datepicker(); }); </script> when i directly call the url to this partial view, so it renders only this view the datepicker works perfectly. (for the purpose of testing this i added the needed jquerry and jquerryui script and css references directly to the partial view) But if i use a Ajax.Actionlink to load this partial view inside a div (called div2, submitting the above form should update div1) like this: <div id="div1"> <%= Ajax.ActionLink("Edit", "/EditData", new { id = Model.id }, new AjaxOptions { HttpMethod = "GET", UpdateTargetId = "div2" } )%> </div> <div2>placeholder for the form</div> the datepicker wont apear anymore. My best guess is the javascript included in the loaded html doesnt get executed, ($(document).ready(function() { $("#datepicker").datepicker(); }); doesnt work either if that's the case how and where should i call the $("datepicker").datepicker(); ? (putting it in the ajaxoptions of the ajax.actionlink as oncomplete = "$(function() { $('#datepicker').datepicker();});" still doesnt work. if thats not the case, then where's my problem?

• How best to use XPath with very large XML files in .NET?

  - by glenatron

  I need to do some processing on fairly large XML files ( large here being potentially upwards of a gigabyte ) in C# including performing some complex xpath queries. The problem I have is that the standard way I would normally do this through the System.XML libraries likes to load the whole file into memory before it does anything with it, which can cause memory problems with files of this size. I don't need to be updating the files at all just reading them and querying the data contained in them. Some of the XPath queries are quite involved and go across several levels of parent-child type relationship - I'm not sure whether this will affect the ability to use a stream reader rather than loading the data into memory as a block. One way I can see of making it work is to perform the simple analysis using a stream-based approach and perhaps wrapping the XPath statements into XSLT transformations that I could run across the files afterward, although it seems a little convoluted. Alternately I know that there are some elements that the XPath queries will not run across, so I guess I could break the document up into a series of smaller fragments based on it's original tree structure, which could perhaps be small enough to process in memory without causing too much havoc. I've tried to explain my objective here so if I'm barking up totally the wrong tree in terms of general approach I'm sure you folks can set me right...

• How do I implement repository pattern and unit of work when dealing with multiple data stores?

  - by Jason

  I have a unique situation where I am building a DDD based system that needs to access both Active Directory and a SQL database as persistence. Initially this wasnt a problem because our design was setup where we had a unit of work that looked like this: public interface IUnitOfWork { void BeginTransaction() void Commit() } and our repositories looked like this: public interface IRepository<T> { T GetByID() void Save(T entity) void Delete(T entity) } In this setup our load and save would handle the mapping between both data stores because we wrote it ourselves. The unit of work would handle transactions and would contain the Linq To SQL data context that the repositories would use for persistence. The active directory part was handled by a domain service implemented in infrastructure and consumed by the repositories in each Save() method. Save() was responsible with interacting with the data context to do all the database operations. Now we are trying to adapt it to entity framework and take advantage of POCO. Ideally we would not need the Save() method because the domain objects are being tracked by the object context and we would just need to add a Save() method on the unit of work to have the object context save the changes, and a way to register new objects with the context. The new proposed design looks more like this: public interface IUnitOfWork { void BeginTransaction() void Save() void Commit() } public interface IRepository<T> { T GetByID() void Add(T entity) void Delete(T entity) } This solves the data access problem with entity framework, but does not solve the problem with our active directory integration. Before, it was in the Save() method on the repository, but now it has no home. The unit of work knows nothing other than the entity framework data context. Where should this logic go? I argue this design only works if you only have one data store using entity framework. Any ideas how to best approach this issue? Where should I put this logic?

• Specific programming text editor for simple open/close editing

  - by queen3

  I'm looking for very specific text editor: Closes on ESC, no project management or tabs Syntax highlighting - preferably with color themes (e.g. can apply different color themes without changing C# coloring definition) or, at least, can load/save themes; support for C/C#/XML/HTML/JavaScript/etc - common MS/.NET world - out of box Configurable keys, or: Shift-Tab shifts blocks XML/HTML auto-completion support - well, optional I use synplus plugin for Total Commander currently, but it has few drawbacks (e.g. crashes sometimes ;-), no auto-completion, etc). Basically I want fast Visual-Studio-like editor that I open, do edits, and then close using ESC. I remember I tried Notepad++, etc - most of them open files in tabs, don't close on ESC... - that is, behave like IDE. At least I've just downloaded Notepad++, it doesn't close on ESC even if I setup keybindings to do so. Autocompletion is optional (though it is to be simple as just tags completion), what I really look for is closing on ESC, not getting in the way with all the tabs and IDE-like, and good coloring. Plus shift-tab is must have for blocks manipulation. Update: any open-source one that I can easily tweak to close on ESC? ;-) Seems like ESC (and reasonable color highlighting) is the core requirement. I've just tried many editors - Programmer's Notepad, E, Crimson, etc - I can't set any of them to close on ESC. Any external tool to close selected program on ESC? ;-) UPDATE: Hm, found an awesome utility for my latest thought: http://www.autohotkey.com. Easy to setup to close any window on ESC (as well as many other tricks). Seems like the most tough requirements is gone - I can use ANY text editor ;-)

• What's the best way to develop a debugging window for an ajax ASP.Net MVC application

  - by KallDrexx

  While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

• Rails 2.3 session

  - by Sam Kong

  Hi, I am developing a rails 2.3.2 app. I need to keep session_id for an order record, retrieve it and finally delete the session_id when the order is completed. It worked when I used cookies as session store but it doesn't for active_record store. (I restarted my browser, so no cache issue.) I know rails 2.3 implements lazy session load. I read some info about it but am still confused. Can somebody clarify how I use session_id for such a case? What I am doing is... A user make an order going through several pages. There is no sign-up, neither login. So I keep session_id in the order record so that no other user can access the order. @order = Order.last :conditions = {:id = params[:id], :session_id = session[:session_id] } When the order is finished, I set nil to session_id column. How would you implement such a case in lazy session(and active_record store) environment? Thanks. Sam

• Datagridview DateTime Format not using System Region settings

  - by Nick

  I've got a datagridview that is hooked up to a bindingsource on my main form. One of the columns and datamembers in the bindingsource is a DateTime object. When the datagridview shows this item it doesn't use Window's default region settings for displaying datetime. The weird thing is, I can access this same DateTime object and print it to a text box, or even pass it off to another form with another datagridview and binding source and it actually shows up properly in that table. So then, why does the datagridview on my main form not use the regional date/time settings when converting the DateTime object to a string? I've checked that there was no special formatting applied to the datagridview and so I'm running out of ideas to check. Do you guys know if there is any super secret way to get a datagridview to follow system regional format rules or not? Also, since I highly doubt that I did something different with this datagridview vs the others in my application, the next potential area for issue could be on application load: Perhaps since this comes up when the application loads, it's not getting the same cultureUI settings as the other datagridviews? Any Help?

• Migration of .NET COM object to 64 bit.

  - by Victor Ronin

  Hi, We have C++ application which uses several COM object. COM object are .NET based (using COM Interop). I need to migrate application to 64 bit. I specifically need C++ application to be 64 bit. I don't want to recompile all of .NET com object to 64 bit and deliver two sets of DLL's (32 bit and 64 bit). I was investigating and found that I can load 32 bit COM Dll's in 32 bit surrogate process using (DllSurrogate in registry). I know how to do that, but it means that all COM objects will become out of process. In the C++ I had the code: CoCreateInstance(CLSID_SomeClass, NULL, CLSCTX_INPROC_SERVER, IID_SomeInterface, (void**)&pobj); It worked fine, but as soon as I switch to CLSCTX_LOCAL_SERVER (and add registry keys for DllSurrogate), it can't find interfaces (error 0x80004002). I checked registry and found out that when .NET COM DLL is registered, it adds ClsID registry keys, but doesn't add Interface and TypeLib registry key. The question is, how to create these registry keys for .NET COM? Regards, Victor

• Execute SQL on CSV files via JDBC

  - by Markos Fragkakis

  Dear all, I need to apply an SQL query to CSV files (comma-separated text files). My SQL is predefined from another tool, and is not eligible to change. It may contain embedded selects and table aliases in the FROM part. For my task I have found two open-source (this is a project requirement) libraries that provide JDBC drivers: CsvJdbc XlSQL JBoss Teiid Create an Apache Derby DB, load all CSVs as tables and execute the query. These are the problems I encountered: it does not accept the syntax of the SQL (it uses internal selects and table aliases). Furthermore, it has not been maintained since 2004. I could not get it to work, as it has as dependency a SAX Parser that causes exception when parsing other documents. Similarly, no change since 2004. Have not checked if it supports the syntax, but seems like an overhead. It needs several entities defines (Virtual Databases, Bindings). From the mailing list they told me that last release supports runtime creation of required objects. Has anyone used it for such simple task (normally it can connect to several types of data, like CSV, XML or other DBS and create a virtual, unified one)? Can this even be done easily? From the 4 things I considered/tried, only 3 and 4 seem to me viable. Any advice on these, or any other way in which I can query my CSV files? Cheers

• Should I move big data blobs in JSON or in separate binary connection?

  - by Amagrammer

  QUESTION: Is it better to send large data blobs in JSON for simplicity, or send them as binary data over a separate connection? If the former, can you offer tips on how to optimize the JSON to minimize size? If the latter, is it worth it to logically connect the JSON data to the binary data using an identifier that appears in both, e.g., as "data" : "< unique identifier " in the JSON and with the first bytes of the data blob being < unique identifier ? CONTEXT: My iPhone application needs to receive JSON data over the 3G network. This means that I need to think seriously about efficiency of data transfer, as well as the load on the CPU. Most of the data transfers will be relatively small packets of text data for which JSON is a natural format and for which there is no point in worrying much about efficiency. However, some of the most critical transfers will be big blobs of binary data -- definitely at least 100 kilobytes of data, and possibly closer to 1 megabyte as customers accumulate a longer history with the product. (Note: I will be caching what I can on the iPhone itself, but the data still has to be transferred at least once.) It is NOT streaming data. I will probably use a third-party JSON SDK -- the one I am using during development is here. Thanks

• Populating cell in UITableView with unique items

  - by aahrens

  I have an array of URL Links that I'm trying to load into a Grouped UITableView. The goal being that I have numberOfSectionsInTableView return [url count] so I can have number of sections equal to the number of url links. Then in numberOfRowsInSection returns 1 so I only populate 1 URL for each section. The trouble I'm having is to ensure that cellForRowAtIndexPath won't keep grabbing the first url link. I suspect it's because it's always grabbing the first url because the rowIndex is always zero. Any ideas how to ensure that each cell in my UITableView is populated with a different url link? - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return [newsItems count]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease]; cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease]; cell.textLabel.lineBreakMode = UILineBreakModeWordWrap; cell.textLabel.numberOfLines = 5; } // Configure the cell. Get the title of the news item that was parsed out int newsItemIndex = [indexPath indexAtPosition: [indexPath length] - 1]; [cell.textLabel setText:[[newsItems objectAtIndex: newsItemIndex] objectForKey: @"link"]]; return cell; }

• Modify Executing Jar file

  - by pinkynobrain

  Hello Stack Overflow friends. I have a simple problem which i fear doesnt have a simple solution and i need advice as to how to proceed. I am developing a java application packaged as and executable JAR but it requires to modify some of its JAR file contents during execution. At this stage i hit a problem because some OS lock the file preventing writes to it. It is essential that the user sees an updated version of the jar file by the time the application exits allthough i can be pretty flexible as to how to achieve this. A clean and efficient solution is obviously prefereable but portability is the only hard requirement. The following are three approaches i can see to solving the problem, feel free to comment on them or suggest others. Tell Java to unlock the JAR file for writing(this doesnt seem possible but it would be the easyest solution) Copy the executable class files to a tempory file on application startup, use a class loader to load these files and unload the ones from the initial JAR file.(Not had much experience with the classloaders but hopefully the JVM would then be smart enough to realize that the original JAR is nolonger in use and so unlock it) Put a Second executable JAR File inside the First, on startup extract the inner jar to e temporaryfile, invoke a new java process and pass it the location of the Outer JAR, first process exits, second process modifys the Outer jar unincumbered.(This will work but im not sure there is a platform independant way of one java app invoking another) I know this is a weird question but any help would be appreciated.

• Stock management of assemblies and its sub parts (relations)

  - by The Disintegrator

  I have to track the stock of individual parts and kits (assemblies) and can't find a satisfactory way of doing this. Sample bogus and hyper simplified database: Table prod: prodID 1 prodName Flux capacitor prodCost 900 prodPrice 1350 (900*1.5) prodStock 3 - prodID 2 prodName Mr Fusion prodCost 300 prodPrice 600 (300*2) prodStock 2 - prodID 3 prodName Time travel kit prodCost 1650 (1350+300) prodPrice 2145 (1650*1.3) prodStock 2 Table rels relID 1 relSrc 1 (Flux capacitor) relType 4 (is a subpart of) relDst 3 (Time travel kit) - relID 2 relSrc 2 (Mr Fusion) relType 4 (is a subpart of) relDst 3 (Time travel kit) prodPrice: it's calculated based on the cost but not in a linear way. In this example for costs of 500 or less, the markup is a 200%. For costs of 500-1000 the markup is 150%. For costs of 1000+ the markup is 130% That's why the time travel kit is much cheaper than the individual parts prodStock: here is my problem. I can sell kits or the individual parts, So the stock of the kits is virtual. The problem when I buy: Some providers sell me the Time Travel kit as a whole (with one barcode) and some sells me the individual parts (with a different barcode) So when I load the stock I don't know how to impute it. The problem when I sell: If I only sell kits, calculate the stock would be easy: "I have 3 Flux capacitors and 2 Mr Fusions, so I have 2 Time travel kits and a Flux Capacitor" But I can sell Kits or individual parts. So, I have to track the stock of the individual parts and the possible kits at the same time (and I have to compensate for the sell price) Probably this is really simple, but I can't see a simple solution. Resuming: I have to find a way of tracking the stock and the database/program is the one who has to do it (I cant ask the clerk to correct the stock) I'm using php+MySql. But this is more a logical problem than a programing one
