• MVC data binding

  - by user441521

  I'm using MVC but I've read that MVVM is sort of about data binding and having pure markup in your views that data bind back to the backend via the data-* attributes. I've looked at knockout but it looks pretty low level and I feel like I can make a library that does this and is much easier to use where basically you only need to call 1 javascript function that will data bind your entire page because of the data-* attributes you assign to html elements. The benefits of this (that I see) is that your view is 100% decoupled from your back-end so that a given view never has to be changed if your back-end changes (ie for asp.net people no more razor in your view that makes your view specific to MS). My question would be, I know there is knockout out there but are there any others that provide this data binding functionality for MVC type applications? I don't want to recreate something that may already exist but I want to make something "better" and easier to use than knockout. To give an example of what I mean here is all the code one would need to get data binding in my library. This isn't final but just showing the idea that all you have to do is call 1 javascript function and set some data-* attribute values and everything ties together. Is this worth seeing through? <script> $(function () { // this is all you have to call to make databinding for POST or GET to work DataBind(); }); </script> <form id="addCustomer" data-bind="Customer" data-controller="Home" data-action="CreateCustomer"> Name: <input type="text" data-bind="Name" data-bind-type="text" /> Birthday: <input type="text" data-bind="Birthday" data-bind-type="text" /> Address: <input type="text" data-bind="Address" data-bind-type="text" /> <input type="submit" value="Save" id="btnSave" /> </form> ================================================= // controller action [HttpPost] public string CreateCustomer(Customer customer) { if(customer.Name == "Rick") return "success"; return "failure"; } // model public class Customer { public string Name { get; set; } public DateTime Birthday { get; set; } public string Address { get; set; } }

• Finance: Friends, not foes!

  - by red@work

  After reading Phil's blog post about his experiences of working on reception, I thought I would let everyone in on one of the other customer facing roles at Red Gate... When you think of a Credit Control team, most might imagine money-hungry (and often impolite) people, who will do nothing short of hunting people down until they pay up. Well, as with so many things, not at Red Gate! Here we do things a little bit differently.   Since joining the Licensing, Invoicing and Credit Control team at Red Gate (affectionately nicknamed LICC!), I have found it fantastic to work with people who know that often the best way to get what you want is by being friendly, reasonable and as helpful as possible. The best bit about this is that, because everyone is in a good mood, we have a great working atmosphere! We are definitely a very happy team. We laugh a lot, even when dealing with the serious matter of playing table football after lunch. The most obvious part of my job is bringing in money. There are few things quite as satisfying as receiving a big payment or one that you've been chasing for a long time. That being said, it's just as nice to encounter the companies that surprise you with a payment bang on time after little or no chasing. It's always a pleasure to find these people who are generous and easy to work with, and so they always make me smile, too. As I'm in one of the few customer facing roles here, I get to experience firsthand just how much Red Gate customers love our software and are equally impressed with our customer service. We regularly get replies from people thanking us for our help in resolving a problem or just to simply say that they think we're great. Or, as is often the case, that we 'rock and are awesome'! When those are the kinds of emails you have to deal with for most of the day, I would challenge anyone to be unhappy! The best thing about my work is that, much like Phil and his counterparts on reception, I get to talk to people from all over the world, and experience their unique (and occasionally unusual) personality traits. I deal predominantly with customers in the US, so I'll be speaking to someone from a high flying multi-national in New York one minute, and then the next phone call will be to a small office on the outskirts of Alabama. This level of customer involvement has led to a lot of interesting anecdotes and plenty of in-jokes to keep us amused! Obviously there are customers who are infuriating, like those who simply tell us that they will pay "one day", and that we should stop chasing them. Then there are the people who say that they ordered the tools because they really like them, but they just can't afford to actually pay for them at the moment. Thankfully these situations are relatively few and far between, and for every one customer that makes you want to scream, there are far, far more that make you smile!

• Getting developers and support to work together

  - by Matt Watson

  Agile development has ushered in the norm of rapid iterations and change within products. One of the biggest challenges for agile development is educating the rest of the company. At my last company our biggest challenge was trying to continually train 100 employees in our customer support and training departments. It's easy to write release notes and email them to everyone. But for complex software products, release notes are not usually enough detail. You really have to educate your employees on the WHO, WHAT, WHERE, WHY, WHEN of every item. If you don't do this, you end up with customer service people who know less about your product than your users do. Ever call a company and feel like you know more about their product than their customer service people do? Yeah. I'm talking about that problem.WHO does the change effect?WHAT was the actual change?WHERE do I find the change in the product?WHY was the change made? (It's hard to support something if you don't know why it was done.)WHEN will the change be released?One thing I want to stress is the importance of the WHY something was done. For customer support people to be really good at their job, they need to understand the product and how people use it. Knowing how to enable a feature is one thing. Knowing why someone would want to enable it, is a whole different thing and the difference in good customer service. Another challenge is getting support people to better test and document potential bugs before escalating them to development. Trying to fix bugs without examples is always fun... NOT. They might as well say "The sky is falling, please fix it!"We need to over train the support staff about product changes and continually stress how they document and test potential product bugs. You also have to train the sales staff and the marketing team. Then there is updating sales materials, your website, product documentation and other items there are always out of date. Every product release causes this vicious circle of trying to educate the rest of the company about the changes.Do we need to record a simple video explaining the changes and email it to everyone? Maybe we should  use a simple online training type app to help with this problem. Ultimately the struggle is taking the time to do the training, but it is time well spent. It may save you a lot of time answering questions and fixing bugs later. How do we efficiently transfer key product knowledge from developers and product owners to the rest of the company? How have you solved these issues at your company?

• It's All In The Cloud

  - by Natalia Rachelson

  People turned out in droves for Steve Miranda's Apps Cloud General Session. Steve, as engaging as ever, covered our Apps strategy in the cloud and reinforced that Oracle has a complete set of cloud services including: •    Human Capital Management•    Talent Management•    Sales and Marketing•    Customer Service and Support•    Financial Management•    Procurement, Sourcing, and Inventory•    Project Portfolio Management•    Governance, Risk, and Compliance... all delivered on top of the Social, Platform, and Common Infrastructure.Steve talked about Fusion being the centerpiece of our Cloud Services. The fact that Fusion is 100 percent standards based is a big, big deal! In addition, our ERP Cloud Service is the most complete cloud service on the market. And email marketing is dead -- social marketing is where the action is. It's also where Oracle is investing heavily from a Sales & Marketing Cloud perspective. Steve covered the strategic acquisitions Oracle has made to enhance our organic Cloud offering. Specifically, Oracle bought RightNow to make our Customer Service and Support Cloud service complete. We also bought Taleo to add Recruiting and Learning capabilities to our Talent Management Cloud. Steve talked about our customers and how they are benefiting from the use of a variety of our Cloud Services. Red Robin is driving lower labor and food costs with Oracle ERP Cloud Service. He used Elizabeth Arden as the profile customer for HCM and Talent Management Service, UBS for HCM and Talent Management Service, and Brocade for Talent Management. All these customers are benefiting from a comprehensive and fully integrated HR platform that aligns compensation with performance and enhances workforce motivation and retention. At the same time, Hitachi Data Systems is using Oracle Taleo Performance Management Cloud to recruit the right competencies, pinpoint areas of improvement, and develop and monitor employee goals to support the global account organization. KLM and Overstock.com are gaining the benefits of Oracle's Customer Service and Support Service from RightNow by better engaging and serving customer needs online and through call centers. And last but not least, Graco and Key Energy are leveraging mobility features and sales forecasting and territory management capabilities within the Oracle Sales and Marketing Service. They expect to gain better visibility to sales information and drive more efficient sales campaigns and empower their sales force with data they need to make sales. Overall, Oracle Apps Cloud Services are enjoying a significant momentum in the marketplace. Steve projected an air of confidence and enthusiasm highlighting Oracle's latest successes with Cloud services.

• Criteria for selecting timeout value?

  - by stijn

  Situation: a piece of software reads frames of data from a file in a seperate thread and puts it on a queue, emptied by another thread. That second thread periodically checks on the queue and fails rather gracefully, by showing an error message stating the read timed out, if no data is available within a certain amount of time. Initially this timeout was set to 200mSec. There was no real reasoning behind that constant though, but it worked fine. We measured on a couple of machines and for large data frames, larger than what would be used by customers, a read took like 20mSec whith no other load on the machine. However one customer now gets timeout errors now and then (on the second try all is fine, probably the file is in cache or the virus scanner leaves it alone). The programmers are like 'well, yeah, but that customer's machine is full of cruft, virus scanners, tons of unneeded background processes etc'. Of course the customer is like 'hey this should just work, shouldn't it'? While the programers have a point, since the software is heavy enough to validate the need for a dedicated machine, that does not make the customer happy. Increasing the timeout to 2 seconds, for example, solves the problem. But I'd like to make a proper decision now instead of just randomly pick some magic constant that is probably ok in 99% of cases. What criteria should be used for that? We could just pick a large number, but that feels wrong. (and then we end up with a program that has the horrible bahaviour of hanging when trying to read from a disconnected drive for instance, whereas we'd rather make it show an error right away). Or we could make the timeout value a user setting, but then we need to ducument it clearly and even then not all customers are tech savy enough to really understand what it does. Or we could try and wait until another customer reports timeouts and increase the value again. And again. Until we find something ok for 99.99% of the cases.. Any good practice for this type of situation?

• Asp.Net MVC - Rob Conery's LazyList - Count() or Count

  - by Adam

  I'm trying to create an html table for order logs for customers. A customer is defined as (I've left out a lot of stuff): public class Customer { public LazyList<Order> Orders { get; set; } } The LazyList is set when fetching a Customer: public Customer GetCustomer(int custID) { Customer c = ... c.Orders = new LazyList<Order>(_repository.GetOrders().ByOrderID(custID)); return c; } The order log model: public class OrderLogTableModel { public OrderLogTableModel(LazyList<Order> orders) { Orders = orders; Page = 0; PageSize = 25; } public LazyList<Order> Orders { get; set; } public int Page { get; set; } public int PageSize { get; set; } } and I pass in the customer.Orders after loading a customer. Now the log i'm trying to make, looks something like: <table> <tbody> <% int rowCount = ViewData.Model.Orders.Count(); int innerRows = rowCount - (ViewData.Model.Page * ViewData.Model.PageSize); foreach (Order order in ViewData.Model.Orders.OrderByDescending(x => x.StartDateTime) .Take(innerRows).OrderBy(x => x.StartDateTime) .Take(ViewData.Model.PageSize)) { %> <tr> <td> <%= order.ID %> </td> </tr> <% } %> </tbody> </table> Which works fine. But the problem is evaluating ViewData.Model.Orders.Count() literally takes about 10 minutes. I've tried with the ViewData.Model.Orders.Count property instead, and the results are the same - takes forever. I've also tried calling _repository.GetOrders().ByCustomerID(custID).Count() directly from the view and that executes perfectly within a few ms. Can anybody see any reason why using the LazyList to get a simple count would take so long? It seems like its trying to iterate through the list when getting a simple count.

• ASP.NET MVC: How can I explain an invalid type violation to an end-user with Html.ValidationSummary?

  - by Terminal Frost

  Serious n00b warning here; please take mercy! So I finished the Nerd Dinner MVC Tutorial and I'm now in the process of converting a VB.NET application to ASP.NET MVC using the Nerd Dinner program as a sort of rough template. I am using the "IsValid / GetRuleViolations()" pattern to identify invalid user input or values that violate business rules. I am using LINQ to SQL and am taking advantage of the "OnValidate()" hook that allows me to run the validation and throw an application exception upon trying to save changes to the database via the CustomerRepository class. Anyway, everything works well, except that by the time the form values reach my validation method invalid types have already been converted to a default or existing value. (I have a "StreetNumber" property that is an integer, though I imagine this would be a problem for DateTime or any other non-strings as well.) Now, I am guessing that the UpdateModel() method throws an exception and then alters the value because the Html.ValidationMessage is displayed next to the StreetNumber field but my validation method never sees the original input. There are two problems with this: While the Html.ValidationMessage does signal that something is wrong, there is no corresponding entry in the Html.ValidationSummary. If I could even get the exception message to show up there indicating an invalid cast or something that would be better than nothing. My validation method which resides in my Customer partial class never sees the original user input so I do not know if the problem is a missing entry or an invalid type. I can't figure out how I can keep my validation logic nice and neat in one place and still get access to the form values. I could of course write some logic in the View that processes the user input, however that seems like the exact opposite of what I should be doing with MVC. Do I need a new validation pattern or is there some way to pass the original form values to my model class for processing? CustomerController Code // POST: /Customers/Edit/[id] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(int id, FormCollection formValues) { Customer customer = customerRepository.GetCustomer(id); try { UpdateModel(customer); customerRepository.Save(); return RedirectToAction("Details", new { id = customer.AccountID }); } catch { foreach (var issue in customer.GetRuleViolations()) ModelState.AddModelError(issue.PropertyName, issue.ErrorMessage); } return View(customer); }

• Shared firewall or multiple client specific firewalls?

  - by Tauren

  I'm trying to determine if I can use a single firewall for my entire network, including customer servers, or if each customer should have their own firewall. I've found that many hosting companies require each client with a cluster of servers to have their own firewall. If you need a web node and a database node, you also have to get a firewall, and pay another monthly fee for it. I have colo space with several KVM virtualization servers hosting VPS services to many different customers. Each KVM host is running a software iptables firewall that only allows specific ports to be accessed on each VPS. I can control which ports any given VPS has open, allowing a web VPS to be accessed from anywhere on ports 80 and 443, but blocking a database VPS completely to the outside and only allowing a certain other VPS to access it. The configuration works well for my current needs. Note that there is not a hardware firewall protecting the virtualization hosts in place at this time. However, the KVM hosts only have port 22 open, are running nothing except KVM and SSH, and even port 22 cannot be accessed except for inside the netblock. I'm looking at possibly rethinking my network now that I have a client who needs to transition from a single VPS onto two dedicated servers (one web and one DB). A different customer already has a single dedicated server that is not behind any firewall except iptables running on the system. Should I require that each dedicated server customer have their own dedicated firewall? Or can I utilize a single network-wide firewall for multiple customer clusters? I'm familiar with iptables, and am currently thinking I'll use it for any firewalls/routers that I need. But I don't necessarily want to use up 1U of space in my rack for each firewall, nor the power consumption each firewall server will take. So I'm considering a hardware firewall. Any suggestions on what is a good approach?

• Suggestions for accessing SQL Server from internet

  - by Ian Boyd

  i need to be able to access a customer's SQL Server, and ideally their entire LAN, remotely. They have a firewall/router, but the guy responsible for it is unwilling to open ports for SQL Server, and is unable to support PPTP forwarding. The admin did open VNC, on a non-stanrdard port, but since they have a dynamic IP it is difficult to find them all the time. In the past i have created a VPN connection that connects back to our network. But that didn't work so well, since when i need access i have to ask the computer-phobic users to double-click the icon and press Connect i did try creating a scheduled task that attempts to keep the VPN connection back to our office up at all times by running: >rasdial "vpn to me" But after a few months the VPN connection went insane, and thought it was both, and neither, connected an disconnected; and the vpn connection wouldn't work again until the server was rebooted. Can anyone think of a way where i can access the customer's LAN that doesn't involve opening ports on the router needing to know their external IP customer interaction of any kind Blah blah blah use vpn vnc protocol has known weaknesses you are unwise to lower your defenses it's not wise to expose SQL Server directly to the internet you stole that line from Empire Customer doesn't care about any of that. Customer wants things to work.

• Order of mod_rewrite rules in .htaccess not being followed

  We're trying to enforce HTTPS on certain URLs and HTTP on others. We are also rewriting URLs so all requests go through our index.php. Here is our .htaccess file. # enable mod_rewrite RewriteEngine on # define the base url for accessing this folder RewriteBase / # Enforce http and https for certain pages RewriteCond %{HTTPS} on RewriteCond %{REQUEST_URI} !^/(en|fr)/(customer|checkout)(.*)$ [NC] RewriteRule ^(.*)$ http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] RewriteCond %{HTTPS} off RewriteCond %{REQUEST_URI} ^/(en|fr)/(customer|checkout)(.*)$ [NC] RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301] # rewrite all requests for file and folders that do not exists RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?query=$1 [L,QSA] If we don't include the last rule (RewriteRule ^(.*)$ index.php?query=$1 [L,QSA]), the HTTPS and HTTP rules work perfectly however; When we add the last three lines our other rules stop working properly. For example if we try to goto https:// www.domain.com/en/customer/login, it redirects to http:// www.domain.com/index.php?query=en/customer/login. It's like the last rule is being applied before the redirection is done and after the [L] flag indicating the the redirection is the last rule to apply.

• Help desk software - specific feature needed

  - by LunchMoney

  I am having a hard time finding help desk software that allows for drop down hyperlink selection during ticket creation. The situation is that we do external support for client systems and connect via remotely anywhere or logmein. Right now we use a poorly modified php based system that has a customer drop down menu and then a site drop down list that is then parsed by a bit of java script which opens a url. What I am looking for is the ability to store customer site URL information in the database and during the creation of a ticket be able to select the customer name and then select the site there by placing the corresponding site URL in the ticket. The support tech will then be able to click on this link to access the customer's site. Has anyone used or seen help desk software with this feature?

• Forwarding emails to nonexisting users/aliases to external mail server

  - by Niclas Lindqvist

  I'm in the works of installing a postfix mailserver on a machine currently being used as web server. As of right now, I've got it working as far as that I can send and receive emails using telnet through port 25. However, as my customer is concerned with downtime, I'd like to setup all the accounts one by one over time, and making sure it works, rather than just cutting the cord to the old mail server and start creating new accounts on the new system. How can I add the domain customer.com to my mail server and just add something like [email protected] to the users and aliases-lists without the web server trying to send all emails with the @customer.com domain to the new mail server? I'm running ubuntu, using postfix and postfix-mysql on the new machine, the old mail server is on a hosted environment somewhere else, where I don't have any control.

• Custom Online Backup Solution Advice

  - by Martín Marconcini

  I have to implement a way so our customers can backup their SQL 2000/5/8 databasase online. The application they use is a C#/.NET35 Winforms application that connects to a SQL Server (can be 2000/2005/2008, sometimes express editions). The SQL Server is on the same LAN. Our application has a very specific UI and we must code each form following those guidelines. There’s lots of GDI+ to give it the look and feel we want. For that reason, using a 3rd party application is not a very good idea. We need to charge the customer on a monthly/annual basis for the service. Preferably, the customer doesn’t need to care about bandwidth and storage space. It must be transparent. Given the above reqs., my first thoughts are: Solution 1: Code some sort of FTP basic functionality with behind the scenes SQL Backup mechanism, then hire a Hosting service and compress-transfer the .BAK to the Hosting. Maintain a series of Folders (for each customer). They won’t see what’s happening. They will just see a list of their files and a big “Backup now” button that will perform the SQL backup, compress it and upload it (and update the file list) ;) Pros: Not very complicated to implement, simple to use, fairly simple to configure (could have a dedicated ftp user/pass) Cons: Finding a “ftp” only hosting plan is not probably going to be easy, they usually come with a bunch of stuff. FTP is not always the best protocol. more? Solution 2: Similar to 1, but instead of FTP, find a cloud computing service like Amazon S3, Mosso or similar. Pros: Cloud Storage is fast, reliable, etc. It’s kind of easy to implement (specially if there are APIs like AWS or Mosso). Cons: I have been unable to come up with a service optimized for resellers where I can give multiple sub-accounts (one for each customer). Billing is going to be a nightmare cuz these services bill per/GB and with One account it’s impossible to differentiate each customer. Solution 3: Similar to 2, but letting the user create their own account on Amazon S3 (for example). Pros: You forget about billing and such. Cons: A mess for the customer who has to open the Amazon (or whatever) account, will be charged for that and not from you. You can’t really charge the customer (since you’re just not doing anything). Solution 4: Use one of the many backup online solutions that use the tech in cloud storage. Pros: many of these include SQL Server backup, and a lot of features that we’d have to implement. Plus web access and stuff like that will come included. Cons: Still have the billing problem described in number 2. Little of these companies (if any) offers “reseller” accounts. You have to eventually use their software (some offer certain branding). Any better approach? Summary: You have a software (.NET Winapp). You want your users to be able to backup their SQL Server databases online (and be able to retrieve the backups if needed). You ideally would like to charge the customer for this service (i.e. XX € a year).

• signed angle between two 3d vectors with same origin within the same plane? recipe?

  - by Advanced Customer

  Was looking through the web for an answer but it seems like there is no clear recipe for it. What I need is a signed angle of rotation between two vectors Va and Vb lying within the same 3D plane and having the same origin knowing that: the plane contatining both vectors is an arbitrary and is not parallel to XY or any other of cardinal planes Vn - is a plane normal both vectors along with the normal have the same origin O = { 0, 0, 0 } Va - is a reference for measuring the left handed rotation at Vn The angle should be measured in such a way so if the plane would be XY plane the Va would stand for X axis unit vector of it. I guess I should perform a kind of coordinate space transformation by using the Va as the X-axis and the cross product of Vb and Vn as the Y-axis and then just using some 2d method like with atan2() or something. Any ideas? Formulas?

• Serve web application error messages from Http server

  - by licorna

  I have nginx as a http server with tomcat as a backend (using proxy_pass). It works great but I want to define my own error pages (404, 500, etc.) and that they are served by nginx and not tomcat. For example I have the following resource: https://domain.com/resource which doesn't exist. If I [GET] that URL then I get a Not Found message from Tomcat and not from nginx. What I want is that every time Tomcat responds with a 404 (or any other error message) nginx sends itself a message to the user: some html file accessible by nginx. The way I have my nginx server configured is very easy, just: location / { proxy_pass http://localhost:8080/<webapp-name>/; } And I've configured port 8080, which is tomcat, as not accessible from outside this machine. I don't think that using different location directives in nginx configuration will work, because there are some resources that depend on the URL: https://domain.com/customer/<non-existent-customer-name>/[GET] Will always return 404 (or any other error message), while: https://domain.com/customer/<existent-customer>/[GET] Will return anything different from 404 (the customer exists). Is there any way of serving Tomcat (Application Server) error messages with Nginx (http Server)? To check the message sent by the proxy_pass directive and act upon it?

• What kind of issues would occur if resolve.conf had no dns servers set?

  - by Stuart Woodward

  I want to create a server for a customer and have that customer finish the configuration for themselves. It was been decided that rather than setting default DNS servers (i.e. something like Google's) that the customer should enter the information by themselves. I assume that the customer is technically competent enough to do this. If however they forget or neglect to set this up they might spend some time trying to figure out what is wrong and eventually contact support. (In this case, I think that setting a default might have been better.) Apart from the obvious inability to resolve hosts, what other issues might they face until they have set valid dns servers in resolve.conf?

• Zeroing SSD drives

  - by jtnire

  We host VPSes for customers. Each customer VPS is given an LVM LV on a standard spindle hard disk. If the customer were to leave, we zero out this LV ensuring that their data does not leak over to another customers. We are thinking of going with SSDs for our hosting business. Given that SSDs have the "wear levelling" technology, does that make zeroing pointless? Does this make this SSD idea unfeasable, given we can't allow customer data to leak over to another customer? Thanks

• Apple iPhone 4S Launch In India On Nov 25

  - by Gopinath

  Aircel, one of the leading wireless mobile services provider of India has just announced that iPhone 4S will be available to its customers on November 25. You can start pre-booking the phone from November 18 through Aircel website or walking into an Aircel showroom near you. My multiple calls to Aircel customer care division were no use to get the details on the price information. Three times the call got disconnected before a customer care executive tried fetching the details on price and models. We hear from BGR India blog that iPhone 4S price is going start at Rs. 40,000 for a 16GB model and may go up to Rs. 50,000 for a 64 GB model. Airtel, another leading mobile service provider in India, who sells iPhone in India is not sure when they are going to start offering iPhone 4S to its customer. I reached customer care regarding the iPhone 4S and they don’t have any details to offer at the moment. It’s good to see Apple releasing iPhone 4S to India markets just after couple of months of International release. Apple was earlier criticized for releasing iPhone 2, iPhone 3G in India almost an year after the international launch while companies like Nokia release their flagship models just after weeks of international launch. One of the most sought after feature of iPhone 4S is Siri and my friends in US told that it works amazingly good. Siri does not have any problem in understanding Indian English accent and it is very good at recognizing the Indian names in contacts list. But at the same time we do hear reports that Siri does not help much if it’s used outside USA. Considering that Siri is a software it should be possible for Apple to improve it to work better outside USA. But who know the priorities of Apple! This article titled,Apple iPhone 4S Launch In India On Nov 25, was originally published at Tech Dreams. Grab our rss feed or fan us on Facebook to get updates from us.

• PetaPoco with stored procedures

  - by Jalpesh P. Vadgama

  In previous post I have written that How we can use PetaPoco with the asp.net MVC. One of my dear friend Kirti asked me that How we can use it with Stored procedure. So decided to write a small post for that. So let’s first create a simple stored procedure for customer table which I have used in my previous post. I have written  simple code a single query that will return customers. Following is a code for that. CREATE PROCEDURE mysp_GetCustomers AS SELECT * FROM [dbo].Customer Now our stored procedure is ready so I just need to change my CustomDB file from the my previous post example like following. using System.Collections.Generic; namespace CodeSimplified.Models { public class CustomerDB { public IEnumerable<Customer> GetCustomers() { var databaseContext = new PetaPoco.Database("MyConnectionString"); return databaseContext.Query<Customer>("exec mysp_GetCustomers"); } } } That's It. Now It's time to run this in browser and Here is the output In future post I will explain How we can use PetaPoco with parameterised stored procedure. Hope you liked it.. Stay tuned for more.. Happy programming.

• Windows CE: SDK Doesn’t Show up in Visual Studio 2008

  - by Bruce Eitman

  A customer recently contacted me because after installing an SDK it didn’t show up in Visual Studio 2008.  So being a good vendor I installed VS2008 and then installed the SDK – no problem the SDK showed up and I could create projects based on it. I let the customer know that the SDK definitely works with VS2008. The customer got back to me and asked what OS I was using. Hmm, how could that play into this? I told him that I use Windows XP, and it turned out that he is way more modern than I am and is using both Windows Vista and 7. The customer opened a support case with Microsoft. The answer turns out to be that the SDK install requires the user to be logged on as an administrator when installing on Windows Vista and 7 for the SDK to show up in Visual Studio 2008. This problem does not seem to exist for Visual Studio 2005 on those operating systems. The actual instructions from Microsoft Support are: 1)      Make sure Visual Studio 2008 is not running. I also shut down the device emulator manager but you may not be using that. 2)      Open a “Visual Studio 2008 Command Prompt” as Administrator. On Windows 7 just right click the short cut and pick the “Run as administrator” option. 3)      Enter the following command: msiexec /log SDKInstallLog.txt /package <the path to your .msi file> 4)      When asked if you wish to do a custom or complete install pick custom 5)      Instruct the installer to omit the installation of the documentation. This was something I found about CE 6 SDK installation issue and may have no bearing upon your problem but I did it anyway. 6)      Install   Copyright © 2010 – Bruce Eitman All Rights Reserved

• Meta-licensing of applications

  - by Gene

  I'm currently evaluating license management solutions for our customized and project-based applications, which are supported by a single server in the intranet of the customer. The applications use common functionality provided by the server (session handling, data synchronization, management capabilities, etc) and are installed on mobile devices. We allow our customers to run the applications on X devices and want to check on the server, whether the customer sticks to this limit (based on the sessions). We don't want licensing software to be installed on the devices itself (for example providing X serials to the customer) nor do we want to host an additional server for licensing in the intranet of the customer. If a client connects, our server should load the license for the application running on the client and verify, that there are sessions left. The licensing managers I looked at (12 products so far) focus on the application itself and don't allow me to implement such a floating behavior as described above. For example, this software could easily be used to create a "Standard Edition" or a "Professional Edition" of our server software, which is not our intention. In XHEO DeployLX there is a "Session Limit", which allows to limit the license to the currently established sessions in ASP.NET, which comes very close to my needs. I'm currently thinking of implementing a custom solution, which allows me to load and enforce custom-defined licenses per application on the server-side and a simple editor to define such licenses (which would contain a type and the limit itself), but I would appreciate an existing, easy to integrate commercial solution. I think it could be possible to use DeployLX for this task, but I would spend a lot of money for implementing most of the solution myself (except for the editor). Thanks in advance for any suggestions or hints. Gene
