  • Windows mobile phone for business application - or design way out of scrolling problem

    - by Peter
    We have a business application written for Windows mobile. It has people doing inventories. The fastest way to do this is to keep one hand on the product being counted and the other on the phone. The five-way lets you hit enter to accept the current correct inventory (the norm) or to move one left to remove one. This is very fast. If I am two low, I have a quick glance at the phone- move my eyes back to count the next row - and with my right hand hit the five way "left left enter". Very fast. Our problem is that with I-Mate out of business, we cannot find a modern cell phone that has a decent size screen and a five way. Everyone is going to candy bar and flicks. That works great if it is two hands and you are looking at the phone, but not efficient for us. Other than the $1,500 ruggadized units, is there anybody who makes a business style Windows Mobile with a five way? If not, any ideas on how to design the phone to make it easier without a five way to quickly enter data like this?

  • adding stock data to amibroker using c#

    - by femi
    hello, I have had a hard time getting and answer to this and i would really , really appreciate some help on this. i have been on this for over 2 weeks without headway. i want to use c# to add a line of stock data to amibroker but i just cant find a CLEAR response on how to instantiate it in C#. In VB , I would do it something like; Dim AmiBroker = CreateObject("Broker.Application") sSymbol = ArrayRow(0).ToUpper Stock = AmiBroker.Stocks.Add(sSymbol) iDate = ArrayRow(1).ToLower quote = Stock.Quotations.Add(iDate) quote.Open = CSng(ArrayRow(2)) quote.High = CSng(ArrayRow(3)) quote.Low = CSng(ArrayRow(4)) quote.Close = CSng(ArrayRow(5)) quote.Volume = CLng(ArrayRow(6)) The problem is that CreateObject will not work in C# in this instance. I found the code below somewhere online but i cant seem to understand how to achieve the above. Type objClassType; objClassType = Type.GetTypeFromProgID("Broker.Application"); // Instantiate AmiBroker objApp = Activator.CreateInstance(objClassType); objStocks = objApp.GetType().InvokeMember("Stocks", BindingFlags.GetProperty,null, objApp, null); Can anyone help me here? Thanks

  • Anyone got a nifty credit expiry algorithm?

    - by garethkeenan
    Our website uses a credit system to allow users to purchase inexpensive digital goods (eg. photos). We use credits, rather than asking the user to pay for items individually, because the items are cheap and we are trying to keep our credit-card/PayPal overhead low. Because we aren't a bank, we have to expire credits after a certain amount of time. We expire deposit credits after a year, but other types of credits (bonuses, prizes, refunds) may have a different shelf-life. When a buyer buys an item, we spend the credit that is going to expire first. Our current system keeps track of every deposit by storing the original value and the remainder to be spent. We keep a list of all purchases as well, of course. I am currently moving to a system which is much more like a traditional double-entry accounting system. A deposit will create a ledger item, increasing the user's 'spending' account balance. Every purchase will also create a ledger item, decreasing the user's 'spending' account balance. The new system has running balances, while the old system does not, which greatly improves our ability to find problems and do reconciliations. We do not want to use the old system of keeping a 'remainder' value attached to each deposit record because it is inefficient to replay a user's activities to calculate what the remainder of each deposit is over time (for the user's statement). So, after all of this verbose introduction, my question is "Does anyone else out there have a similar system of expiring credits?" If you could describe how you calculate expired credits it would be a great help. If all expired credits had the exact same shelf life, we would be able to calculate the expired amount using: Total Deposits - Total Spending - Deposits Not Due To Expire = Amount to Expire However, because deposits can have different shelf lives, this formula does not work because more than one deposit can be partially spent at any given time.

  • How can I build something like Amazon S3 in Perl?

    - by Joel G
    I am looking to code a file storage application in perl similar to amazon s3. I already have a amazon s3 clone that I found online called parkplace but its in ruby and is old also isn't built for high loads. I am not really sure what modules and programs I should use so id like some help picking them out. My requirements are listed below (yes I know there are lots but I could start simple then add more once I get it going): Easy API implementation for client side apps. (maybe REST (?) Centralized database server for the USERDB (maybe PostgreSQL (?). Logging of all connections, bandwidth used, well pretty much everything to a centralized server (maybe PostgreSQL again (?). Easy server side configuration (config file(s) stored on the servers). Web based control panel for admin(s) and user(s) to show logs. (could work just running queries from the databases) Fast High Uptime Low memory usage Some sort of load distribution/load balancer (maybe a dns based or pound or perlbal or something else (?). Maybe a cache of some sort (memcached or parlbal or something else (?). Thanks in advance

  • Is there a way in .NET to access the bytecode/IL/CLR that is currently running?

    - by Alix
    Hi. I'd like to have access to the bytecode that is currently running or about to run in order to detect certain instructions and take specific actions (depending the instructions). In short, I'd like to monitor the bytecode in order to add safety control. Is this possible? I know there are some AOP frameworks that notify you of specific events, like an access to a field or the invocation of a method, but I'd like to skip that extra layer and just look at all the bytecode myself, throughout the entire execution of the application. I've already looked at the following questions (...among many many others ;) ):     Preprocessing C# - Detecting Methods     What CLR/.NET bytecode tools exist? as well as several AOP frameworks (although not in great detail, since they don't seem to do quite what I need) and I'm familiar with Mono.Cecil. I appreciate alternative suggestions, but I don't want to introduce the overhead of an AOP framework when what I actually need is access to the bytecode, without all the stuff they add on top to make it more user-friendly (... admittedly very useful stuff when you don't want to go low-level). Thanks :)

  • How do I develop browser plugins with cross-platform and cross-browser compatibility in mind?

    - by Schnapple
    My company currently has a product which relies on a custom, in-house ActiveX control. The technology it employs (TWAIN) is itself cross-platform by design, but our solution is obviously limited to Internet Explorer on Windows. Long term we would like to become cross-browser and cross-platform (i.e., support other browsers on Windows, support the Macintosh or Linux). Obviously if we wanted to support Firefox on Windows I would need to write a plugin for it. But if we wanted to support the Macintosh, how do I attack that? Is it possible to compile a version of the Firefox plugin that runs on the Mac? Would I be remiss to not also support Safari on the Mac? Are there any plugins which are cross-browser on a platform? (i.e., can any browsers run plugins for other browsers) Since TWAIN is so low-level to the operating system, I do not think Java would be a solution in any capacity, but I could be wrong. What do people generally do when they want to support multiple platforms with a process that will need to be cross-platform and cross-browser compatible?

  • .NET: How do I know if I have an unmanaged resource?

    - by Shiftbit
    I've read that unmanaged resource are considered file handles, streams, anything low level. Does MSDN or any other source explain how to recognize an unmanaged resource? I can't seem to find any examples on the net that show unmanaged code, all the examples just have comments that say unmanaged code here. Can someone perhaps provide a realworld example where I would handle an unmanaged resources in an IDispose interface? I provided the IDisposable interface for your convience. How do I identify an unmanaged resource? Thanks in advance! IDisposable Reference Public Class Sample : Implements IDisposable Private disposedValue As Boolean = False 'To detect redundant calls ' IDisposable Protected Overridable Sub Dispose(ByVal disposing As Boolean) If Not Me.disposedValue Then If disposing Then ' TODO: free other state (managed objects). End If ' TODO: free your own state (unmanaged objects). ' TODO: set large fields to null. End If Me.disposedValue = True End Sub ' This code added by Visual Basic to correctly implement the disposable pattern. Public Sub Dispose() Implements IDisposable.Dispose ' Do not change this code. Put cleanup code in Dispose(ByVal disposing As Boolean) above. Dispose(True) GC.SuppressFinalize(Me) End Sub End Class

  • How to organize the work when project needs to be re-implemented due to poor code quality?

    - by Dmitriy Nagirnyak
    Hi, I have joined a very small where one main developer has been buiding the web app (.NET 4.0) during ~6 months. The project should be delivered within next 2 months. After first look at the code I can say that I would never allow it to go to production (things like catch { }, not tests at all with WebForms etc). So the code quality is incredibly low. My task is to improve that and still deliver the solution. So I plan to start with unit testing and MVC2 reimplementing most of the functionality (though using some of the existing code). I estimate that I will need about 6 weeks to catch up with the current progress and be on te same functionality level as the application will be in 6 months. The problem is that the main developer who has been working on the project does not seem to be very 'professional' and skillful (he seems to be really starting in IT and many basic things are unknown to him). It will take significant amount of time and effort to educate him how to do the proper testing, development and apply some patterns. I am ready to take responsibility for the reimplemnting the application but at the same time I don't want the main developer to be on idle but as he won't be able to significantly contribute to the better-world project at this stage I am not sure what would the best way to keep productivity high for both of us. Currently I think following solution is good enough: He proceeds doing what he does until I will catch up with him and then start working on a new project together. The problem is that of course this approach is not very productive as one developer will do better-world project while the other will proceed with what he did, effectively doing similar tasks. Can you suggest how we could better organise the work together in order to be most efficient for the overall project? Thanks, Dmitriy.

  • Rendering PDF on WebPage

    - by Priyank
    Hi. We are trying to load a pdf file in web browser using pdfobject javascript api. Currently the size of the pdf's that we are trying to display is close to 10MBs. This creates a long delay in displaying a PDF on web page; while the complete PDF gets downloaded. We need to remove this lag by achieving either of the alternatives: Show a progress bar until the PDF is actually displayed. We couldn't find an event which is triggered and can be used to find out if pdf is visible now. This lacking doesn't let us decide when to stop showing progress bar/spinner OR lazy load the PDF such that it gets displayed as soon as first page gets loaded. With that ateast user will have a visual indication as to something is happening. We couldn'find anything in pdf object that lets us do a lazy load. User alternative pdf rendering api; this is a low priority as we already have complete code in place; but in an event of first 2 alternatives not being met; we'd have to consider this option. So please feel free to suggest. Any other ideas as to how user interaction can be made more intuitive or pleasant; would be welcome. Cheers

  • Looking for Recommendations on Version Control System with Intuitive (.NET) API?

    - by John L.
    I'm working on a project which generates (composite) Microsoft Word documents which are comprised of one or more child documents. There are tens of thousands of permutations of the composite documents. Far too many for users to easily manage. Users will need to view/edit the child documents through the app which hides all of the nasty implementation details. A requirement of the system is that the child documents must be version controlled. That is what has been tripping me up. I've been torn between using an off-the-shelf solution or rolling my own. At a minimum, the system needs to support get latest, get specific version, add new, rename and possibly delete. I’ve whiteboarded it enough to realize it won’t be a trivial task to create my own. As far as commercial systems I have VSS and TFS at my disposal. I've played with the TFS API some, but it isn’t as intuitive or well documented as I had hoped. I'm not averse to an open source solution (e.g. SVN), but I have less familiarity with them. Which approach or tool would you recommend? Why? Do you have any links to API documentation you would recommend? Environment: C#, VS2008, SQL Server 2005/2008, low volume (a few hundred operations per day)

  • Debugging NSoperation BAD ACCESS within graphics context

    - by Joe
    I tried everything to debug this one but I can't get to the bottom of it. This code lives in a subclass of NSOperation which is processed from a queue: (borders is an ivar NSArray containing 5 UIimage objects) NSMutableArray *images = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < 5; i++) { CGSize size = CGSizeMake(60, 60); UIGraphicsBeginImageContext(size); CGPoint thumbPoint = CGPointMake(6, 6); [controller.image drawAtPoint:thumbPoint]; CGPoint borderPoint = CGPointMake(0, 0); [[borders objectAtIndex:i] drawAtPoint:borderPoint]; [images addObject:UIGraphicsGetImageFromCurrentImageContext()]; UIGraphicsEndImageContext(); } [images release]; The code works fine most of the time but when I push the iphone by access subviews and pressing lots of buttons on the UI I either get this exception which is trapped by the operation: Exception Load view: *** -[NSCFArray insertObject:atIndex:]: attempt to insert nil or I get this: Program received signal: “EXC_BAD_ACCESS”. The exception is caused because UIGraphicsGetImageFromCurrentImageContext() return nil. I don't know how to debug the EXC_BAD_ACCESS but I'm guessing that this error (in fact both of these errors) is caused by low memory. The debugger stops at the line: [controller.image drawAtPoint:thumbPoint]; As I mentioned I've trapped the exception so I can live with that but the EXC_BAD_ACCESS is more serious. IF this is memory related how can I tell and is it possible to increase the memory available to NSOperation?

  • Haskell Linear Algebra Matrix Library for Arbitrary Element Types

    - by Johannes Weiß
    I'm looking for a Haskell linear algebra library that has the following features: Matrix multiplication Matrix addition Matrix transposition Rank calculation Matrix inversion is a plus and has the following properties: arbitrary element (scalar) types (in particular element types that are not Storable instances). My elements are an instance of Num, additionally the multiplicative inverse can be calculated. The elements mathematically form a finite field (??2256). That should be enough to implement the features mentioned above. arbitrary matrix sizes (I'll probably need something like 100x100, but the matrix sizes will depend on the user's input so it should not be limited by anything else but the memory or the computational power available) as fast as possible, but I'm aware that a library for arbitrary elements will probably not perform like a C/Fortran library that does the work (interfaced via FFI) because of the indirection of arbitrary (non Int, Double or similar) types. At least one pointer gets dereferenced when an element is touched (written in Haskell, this is not a real requirement for me, but since my elements are no Storable instances the library has to be written in Haskell) I already tried very hard and evaluated everything that looked promising (most of the libraries on Hackage directly state that they wont work for me). In particular I wrote test code using: hmatrix, assumes Storable elements Vec, but the documentation states: Low Dimension : Although the dimensionality is limited only by what GHC will handle, the library is meant for 2,3 and 4 dimensions. For general linear algebra, check out the excellent hmatrix library and blas bindings I looked into the code and the documentation of many more libraries but nothing seems to suit my needs :-(. Update Since there seems to be nothing, I started a project on GitHub which aims to develop such a library. The current state is very minimalistic, not optimized for speed at all and only the most basic functions have tests and therefore should work. But should you be interested in using or helping out developing it: Contact me (you'll find my mail address on my web site) or send pull requests.

  • Linux Lightweight Distro and X Windows for Development

    - by Fernando Barrocal
    Heyall... I want to build a lightweight linux configuration to use for development. The first idea is to use it inside a Virtual Machine under Windows, or old Laptops with 1Gb RAM top. Maybe even a distributable environment for developers. So the whole idea is to use a LAMP server, Java Application Server (Tomcat or Jetty) and X Windows (any Window manager, from FVWM to Enlightment), Eclipse, maybe jEdit and of course Firefox. Edit: I am changing this post to compile a possible list of distros and window managers that can be used to configure a real lightweight development environment. I am using as base personal experiences on this matter. Info about the distros can be easily found in their sites. So please, focus on personal use of those systems Distros Ubuntu / Xubuntu Pros: Personal Experience in old systems or low RAM environment - @Schroeder, @SCdF Several sugestions based on personal knowledge - @Kyle, @Peter Hoffmann Gentoo Pros: Not targeted to Desktop Users - @paan Don't come with a huge ammount of applications - @paan Slackware Pros: Suggested as best performance in a wise install/configuration - @Ryan Damn Small Linux Pros: Main focus is the lightweight factor - 50MB LiveCD - @Ryan Debian Pros: Very versatile, can be configured for both heavy and lightweight computers - @Ryan APT as package manager - @Kyle Based on compatibility and usability - @Kyle -- Fell Free to add Prós and Cons on this, so we can compile a good Reference. -- X Windows suggestion keep coming about XFCE. If others are to add here, open a session for it Like the distro one :)

  • Getting SSL to work with Apache/Passenger on OSX

    - by jonnii
    I use apache/passenger on my development machine, but need to add SSL support (something which isn't exposed through the control panel). I've done this before in production, but for some reason I can't seem to get it work on OSX. The steps I've followed so far are from a default apache osx install: Install passenger and passenger preference pane. Add my rails app (this works) Create my ca.key, server.crt and server.key as detailed on the apple website. At this point I need to start editing the apache configs, so I added: # Apache knows to listen on port 443 for ssl requests. Listen 443 Listen 80 I thought I'd try editing the passenger pref pane generated config first to get everything working, when I add: It starts off looking like this <VirtualHost *:80> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <Directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </Directory> </VirtualHost> I then append this: <VirtualHost *:443> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </directory> # SSL Configuration SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP SSLOptions +FakeBasicAuth +ExportCertData +StdEnvVars +StrictRequire #Self Signed certificates SSLCertificateFile /private/etc/apache2/ssl.key/server.crt SSLCertificateKeyFile /private/etc/apache2/ssl.key/server.key SSLCertificateChainFile /private/etc/apache2/ssl.key/ca.crt SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 </VirtualHost> The files referenced all exist (I doubled checked that), but now when I restart my apache I can't even get to myapp.local. However apache can still server the default page when I click on it in the sharing preference panel. Any help would be greatly appreciated.

  • How does real-time collaboration with multiple clients work in a system using operation transformati

    - by Saikat Chakrabarti
    I just finished reading High-Latency, Low-Bandwidth Windowing in the Jupiter Collaboration System and I mostly followed everything until part 6: global consistency. This part describes how the system described in the paper can be extended to accomodate for multiple clients connected to the server. However, the explanation is very short and essentially says the system will work if the central server merely forwards client messages to all the other clients. I don't really understand how this works though. What state vector would be sent in the message that is sent to all the other clients? Does the server maintain separate state vectors for each client? Does it maintain a separate copy of the widgets locally for each client? The simple example I can think of is this setup: imagine client A, server, and client B with client A and client B both connected to the server. To start, all three have the state object "ABCD". Then, client A sends the message "insert character F at position 0" at the same time client B sends the message "insert character G at position 0" to the server. It seems like simply relaying client A's message to client B and vice versa doesn't actually handle this case. So what exactly does the server do?

  • video streaming infrastructure

    - by alchemical
    We would like to set-up a live video-chat web site and are looking for basic architectural advice and/or a recomendation for a particular framework to use. Here are the basic features of the site: Most streams will be broadcast live from a single person with a web cam, etc., and viewed by typically 1-10 people, although there could be up to 100+ viewers on the high side. Audio and video do not have to be super-high quality, but do need to be "good enough". The main point is to convey the basic info in the video (and audio). If occasionally the frame-rate drops low and then goes back to normal fairly soon, we could live with that. Budget is an issue, so we are in general looking for a lower cost solution that will give us most of what we need in temers of performance and quality. We are looking at Peer1 for co-lo. The rest of our web site will be .Net / Windows platform. We are open to looking at any platform for the best streaming solution, although our technical expertise is currently more on the Windows side.

  • Determining failing sectors on portable flash memory

    - by Faxwell Mingleton
    I'm trying to write a program that will detect signs of failure for portable flash memory devices (thumb drives, etc). I have seen tools in the past that are able to detect failing sectors and other kinds of trouble on conventional mechanical hard drives, but I fear that flash memory does not have the same kind of predictable low-level access to the hardware due to the internal workings of the storage. Things like wear-leveling and other block-remapping techniques (to skip over 'dead' sectors?) lead me to believe that determining if a flash drive is failing will be difficult at best, if not impossible (short of having constant read failures and device unmounts). Flash drives at their end-of-life should be easy to detect (constant CRC discrepancies during reads and all-out failure). But what about drives that might be failing early? Are there any tell-tale signs like slower throughput speeds that might indicate a flash drive is going to fail much sooner than normal? Along the lines of detecting potentially bad blocks, I had considered attempting random reads/writes to a file close to or exactly the size of the entire volume, but even then is it possible that the drive might report sizes under its maximum capacity to account for 'dead' blocks? In short, is there any way to circumvent or at least detect (algorithmically or otherwise) the use of block-remapping or other life extension techniques for flash memory? Let me end this question by expressing my uncertainty as to whether or not this belongs on serverfault.com . This is definitely a hardware-related question, but I also desire a software solution - preferably one that I can program myself. If this question is misplaced, I will be happy to migrate it to serverfault - but I do need a programming solution. Please let me know if you need clarification :) Thanks!

  • HTML Element doesn't display when served with php5, restart server with php4 and Element displays.

    - by togglemedia
    Get this...I start the server in php5 and a specific HTML element ('a' element with a background image) is nowhere to be seen, I reboot the server in php4 and the HTML element is displaying properly. I boot back and forth between php5 and php4 with absolute consistent results, not displaying in php5 and displaying in php4. The thing that blows my mind is that: the HTML is consistent between boots of php5/4, so both scenarios have the necessary HTML elements the CSS is consistent between boots of php5/4, so both scenarios have the necessary CSS definitions there is an identically styled sibling element, with different class name that displays properly the problem is reproducible between browsers, between platforms. I've tested it on every possible config, Mac/Windows, IE6,7,8, FireFox, Safari etc... When the server is booted in php5 there is one HTML element that just doesn't display/render. A stab in the dark, I turned on PHP error reporting in php5 (to see if there would be any clues there) and low and behold the HTML element is now rendering in php5. I turn off PHP error reporting, and restart php5 and the HTML element is still rendering in php5, and the problem has been fixed...and I can't get the problem to reproduce. This is why my curiosity has brought me here. I just spent about four hours scratching my head trying to figure out how this could be. And now, I ask any php web dev gurus out there...what the heck was this all about?

  • Which technology is best suited to store and query a huge readonly graph?

    - by asmaier
    I have a huge directed graph: It consists of 1.6 million nodes and 30 million edges. I want the users to be able to find all the shortest connections (including incoming and outgoing edges) between two nodes of the graph (via a web interface). At the moment I have stored the graph in a PostgreSQL database. But that solution is not very efficient and elegant, I basically need to store all the edges of the graph twice (see my question PostgreSQL: How to optimize my database for storing and querying a huge graph). It was suggested to me to use a GraphDB like neo4j or AllegroGraph. However the free version of AllegroGraph is limited to 50 million nodes and also has a very high-level API (RDF), which seems too powerful and complex for my problem. Neo4j on the other hand has only a very low level API (and the python interface is not mature yet). Both of them seem to be more suited for problems, where nodes and edges are frequently added or removed to a graph. For a simple search on a graph, these GraphDBs seem to be too complex. One idea I had would be to "misuse" a search engine like Lucene for the job, since I'm basically only searching connections in a graph. Another idea would be, to have a server process, storing the whole graph (500MB to 1GB) in memory. The clients could then query the server process and could transverse the graph very quickly, since the graph is stored in memory. Is there an easy possibility to write such a server (preferably in Python) using some existing framework? Which technology would you use to store and query such a huge readonly graph?

  • Configure IIS7 to server static content through ASP.NET Runtime

    - by Anton Gogolev
    I searched high an low and still cannot find a definite answer. How do I configure IIS 7.0 or a Web Application in IIS so that ASP.NET Runtime will handle all requests -- including ones to static files like *.js, *.gif, etc? What I'm trying to do is as follows. We have kind of SaaSy site, which we can "skin" for every customer. "Skinnig" means developing a custom master page and using a bunch of *.css and other images. Quite naturally, I'm using VirtualPathProvider, which operates like this: public override System.Web.Hosting.VirtualFile GetFile(string virtualPath) { if(PhysicalFileExists(virtualPath)) { var virtualFile = base.GetFile(virtualPath); return virtualFile; } if(VirtualFileExists(virtualPath)) { var brandedVirtualPath = GetBrandedVirtualPath(virtualPath); var absolutePath = HttpContext.Current.Server.MapPath(brandedVirtualPath); Trace.WriteLine(string.Format("Serving '{0}' from '{1}'", brandedVirtualPath, absolutePath), "BrandingAwareVirtualPathProvider"); var virtualFile = new VirtualFile(brandedVirtualPath, absolutePath); return virtualFile; } return null; } The basic idea is as follows: we have a branding folder inside our webapp, which in turn contains folders for each "brand", with "brand" being equal to host name. That is, requests to http://foo.example.com/ should use static files from branding/foo_example_com, whereas http://bar.example.com/ should use content from branding/bar_example_com. Now what I want IIS to do is to forward all requests to static files to StaticFileHandler, which would then use this whole "infrastructure" and serve correct files. However, try as I might, I cannot configure IIS to do this.

  • Handling conflicting priorities and expectations in project development

    - by jasonk
    There are any number of situations in the standard day where priority conflicts exist for projects. Management wants maximum productivity from employees. Marketing wants maximum salability and fast turnaround. Ownership wants maximum profit. Customers want usability and low cost. Regardless of the origin of the demands, time and money are always the limiting factor in business. Sometimes project elements have intrinsic or goodwill benefits for which there is not a hard, fast way to measure with monetary means (e.g. arguments for an attractive UI appeal vs. functional but plain). Other elements of software may have a method of providing “mental breaks” or motivating “cool factor” for developers that can get them back on track on other bigger, complex issues. While they may sidetrack the project short term they may have greater results long term through improved job satisfaction, etc. Continued training is a must, but working it in can setup back progress. What are your suggestions for setting priorities? How do you evaluate requests/demands on your projects? What are your suggestions for communicating and passing those on to your team in a way that they stay focused?

  • Problem with Binding Multiple Objects on WPF

    - by Diego Modolo Ribeiro
    Hi, I'm developing a user control called SearchBox, that will act as a replacer for ComboBox for multiple records, as the performance in ComboBox is low for this scenario, but I'm having a big binding problem. I have a base control with a DependencyProperty called SelectedItem, and my SearchControl shows that control so that the user can select the record. The SearchControl also has a DependencyProperty called SelectedItem on it, and it is being updated when the user selects something on the base control, but the UI, wich has the SearchControl, is not being updated. I used a null converter so that I could see if the property was updating, but it's not. Below is some of the code: This is the UI: <NectarControles:MaskedSearchControl x:Name="teste" Grid.Row="0" Grid.Column="1" Height="21" ItemsSource="{Binding C001_Lista}" DisplayMember="C001_Codigo" Custom:CustomizadorTextBox.CodigoCampo="C001_Codigo" ViewType="{x:Type C001:C001_Search}" ViewModelType="{x:Type C001_ViewModel:C001_ViewModel}" SelectedItem="{Binding Path=Instancia.C001_Holding, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource DebuggingConverter}}"> </NectarControles:MaskedSearchControl> This is the relevante part of the SearchControl: Binding selectedItemBinding = new Binding("SelectedItem"); selectedItemBinding.Source = this.SearchControlBase; selectedItemBinding.Mode = BindingMode.TwoWay; selectedItemBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged; this.SetBinding(SelectedItemProperty, selectedItemBinding); ... public System.Data.Objects.DataClasses.IEntityWithKey SelectedItem { get { return (System.Data.Objects.DataClasses.IEntityWithKey)GetValue(SelectedItemProperty); } set { SetValue(SelectedItemProperty, value); if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("SelectedItem")); } } Please someone help me... Tks...

  • Rails form protection questions, hidden field

    - by user284194
    I have a live rails website and I want to have a form with a lot of fields on it. I have set up validations and allowed formatting for every field. I've tested it quite a bit and it seems to catch anything I throw at it. I think it's almost ready to go live, but I want to quadruple check if there's anything else I should do to protect it. My site has a low volume of visitors, but I want it to be a safe as possible. I'd like to avoid using a captcha if I can. I've read that you can use a hidden field to protect forms against bots. Do people recommend this instead of using a captcha, or even using it with a captcha? my form is really standard: <% form_for(@entry) do |f| %> ... <%= f.submit 'Create' %> <% end %> Any suggestions or code samples would be greatly appreciated.

  • How do you concat multiple rows into one column in SQL Server?

    - by Jason
    I've searched high and low for the answer to this, but I can't figure it out. I'm relatively new to SQL Server and don't quite have the syntax down yet. I have this datastructure (simplified): Table "Users" | Table "Tags": UserID UserName | TagID UserID PhotoID 1 Bob | 1 1 1 2 Bill | 2 2 1 3 Jane | 3 3 1 4 Sam | 4 2 2 ----------------------------------------------------- Table "Photos": | Table "Albums": PhotoID UserID AlbumID | AlbumID UserID 1 1 1 | 1 1 2 1 1 | 2 3 3 1 1 | 3 2 4 3 2 | 5 3 2 | I'm looking for a way to get the all the photo info (easy) plus all the tags for that photo concatenated like CONCAT(username, ', ') AS Tags of course with the last comma removed. I'm having a bear of a time trying to do this. I've tried the method in this article but I get an error when I try to run the query saying that I can't use DECLARE statements... do you guys have any idea how this can be done? I'm using VS08 and whatever DB is installed in it (I normally use MySQL so I don't know what flavor of DB this really is... it's an .mdf file?)
