  • Program for WIndows Embedded

    - by Syma
    Hi, We have request from our clients to provide a POS terminal version of our web-based software. They want to be able to enter record to their database from POS terminal (via web service) instead of using PC browser. I am the one to develop this application, as I am the lead developer of the main application. I haven't done any Windows embedded programming or .net compact edition before and would appreciate link to good tutorial or info on how to start developing for Windows CE 6.0 enabled POS terminal or device. Thanks

  • A new MEF error I've not seen before -- "The export is not assignable to type..."

    - by Dave
    I was very surprised to get this error today, as it's one that I've never encountered before. Everything in the code looked okay, so I did some searches. The previous questions and their respective answers didn't help. This one was solved when the poster made sure his assembly references were consistent. I don't have this issue right now because I'm currently referencing another project in my solution. This one was solved when the poster was instructed to use ImportMany, but I am already using it (I think properly, too) to try to load multiple plugins This one was solved when the poster realized that there was a platform target mismatch. I've already gone through my projects to ensure that everything targets x86. So here's what I am trying to do. I have a plugin that owns a connection to a device. I might also need to be able to share that connection with another plugin. I decided that the cleanest way to do this was to create an interface that would allow the slave plugin to request its own connection to the device. Let's just call it IConnectionSharer. If the slave plugin does not need to borrow this connection and has its own, then it should use its own implementation of IConnectionSharer to connect to the device. My "master" plugin (the one that owns the connection to the device) implements IConnectionSharer. It also exports this via ExportAttribute. My "slave" plugin assembly defines a class that also implements and exports IConnectionSharer. When the application loads, the intent is for my slave plugin, via MEF, to enumerate all IConnectionSharers and store them in an IEnumerable<IConnectionSharer>. It does so like this: [ImportMany] public IEnumerable<IConnectionSharer> AllSharedConnections { get; set; } But during part composition, I get the error the export 'Company.MasterPlugin (ContractName="IConnectionSharer")' is not assignable to type 'IConnectionSharer'. The error message itself seems clear enough -- it's as if MEF thinks my master plugin doesn't inherit from IConnectionSharer... but it does! Can anyone suggest further debugging strategies? I'm going to start the painful process of single stepping through the MEF source.

  • browser instant updates with ajax/jquery

    - by wcpro
    I'm trying to reverse engineer how facebook handles their notifications, where when you get a message you get instantly notified via the browser. I've fiddled with it for a little bit and realized that there is always a pending GET request "listening" if you will to some sort of update from the server. This appears to be some sort of observer pattern. I was just wondering if this pattern was documented somewhere.

  • Creating a POST body in VBA

    - by Moses Ting
    Does anyone know how to construct a POST DATA body in VBA? I'm trying to upload rather lengthy strings via a post call using the "Microsoft.XMLHTTP" object. I'm not tied to using that object for making the HTTP request either.

  • After Repo sync, there are no files int he directory.

    - by taranfx
    I've setup a new Repo for Android source code, and after executing the repo sync, there are no files in the repo directory. Did I miss something? I used: repo init -u git://android.git.kernel.org/platform/manifest.git repo initialized in /home/tarandeep/code/Android repo sync ... It downloaded GBs of data (I can confirm via network monitor) and then nothing appeared in the Android directory.

  • Will First() perform the OrderBy()?

    - by Martin
    Is there any difference in (asymptotic) performance between Orders.OrderBy(order => order.Date).First() and Orders.Where(order => order.Date == Orders.Max(x => x.Date)); i.e. will First() perform the OrderBy()? I'm guessing no. MSDN says enumerating the collection via foreach och GetEnumerator does but the phrasing does not exclude other extensions.

  • How do you deploy your Rails application?

    - by Michael Sync
    Do you upload your rail application to your host via FTP first? I'm currently using Passenger and Capistrano. If I do "cap deploy" in my local machine then I think Capistrano should upload my rail application to my host, right? Someone from my host is saying that I need to run "cap deploy" in server. I think it doesn't make sense.

  • What is the best way to create a Singleton Webservice in PHP?

    - by ChronoFish
    Hello, We have a need to access a DB that only allows one connection at a time. This screams "singleton" to me. The catch of course is that the singleton connection will be exposed (either directly or indirectly) via a web-service (most probable a SOAP based web-service - located on a separate server from the calling app(s) ) - which means that there may be more than one app / instance attempting to connect to the singleton class. In PHP, what is the best way to create a global singleton or a web-service singleton? TIA

  • Resizing of AS-based Flash app from FireFox vs. IE...

    - by bferster
    I have put in some controls to allow users to resize my Flash app via Javascript: document.getElementById("flashApp").height*=1.25; document.getElementById("flashApp").width*=1.25; This works great in IE/Safari, but is ignored in Firefox. I know it's talking the the flash app and gets and sets the height/width vars ok, but the same code run in FireFox ignores the scaling. (It's not the DOC spec issue) Any thoughts? Bill
