• Seed data for grails application

  - by bsreekanth

  Hello, What is the best way to load seed (initial or test) data into grails application. I'm considering 3 options 1. Putting everything in *BootStrap.groovy files. This is tedious if the domain classes and test data are many. 2. Write custom functionality to load it through xml. May not be too difficult with the excellent xml support by groovy, but lot of switch statements for different domain classes. 3. Use Liquibase LoadData api. I see you can load the data fairly easy from csv files. Choice 3 seems the easiest. But, I'm not familiar with Liquibase. Is it good in this scenario, or only used for migration, db changes etc. If anyone could provide a better sol, or point to an example with Liquibase, it would be great help.. thanks...

• PycURL RESUME_FROM

  - by excid3

  I can't seem to get the RESUME_FROM option to work. Here's some example code that I have been testing with: import os import pycurl import sys def progress(total, existing, upload_t, upload_d): try: frac = float(existing)/float(total) except: frac = 0 sys.stdout.write("\r%s %3i%%" % ("file", frac*100) ) url = "http://launchpad.net/keryx/stable/0.92/+download/keryx_0.92.4.tar.gz" filename = url.split("/")[-1].strip() def test(debug_type, debug_msg): print "debug(%d): %s" % (debug_type, debug_msg) c = pycurl.Curl() c.setopt(pycurl.URL, url) c.setopt(pycurl.FOLLOWLOCATION, 1) c.setopt(pycurl.MAXREDIRS, 5) # Setup writing if os.path.exists(filename): f = open(filename, "ab") c.setopt(pycurl.RESUME_FROM, os.path.getsize(filename)) else: f = open(filename, "wb") c.setopt(pycurl.WRITEDATA, f) #c.setopt(pycurl.VERBOSE, 1) c.setopt(pycurl.DEBUGFUNCTION, test) c.setopt(pycurl.NOPROGRESS, 0) c.setopt(pycurl.PROGRESSFUNCTION, progress) c.perform()

• capybara selenium and JavaScript Destroy

  - by dorelal

  I am using rails 2.3.5 and this is what I did. I have latest cucumber, cucumber-rails and capybara installed. rails demo cd demo ruby script/generate cucumber --rspec --capybara ruby script/generate feature post title:string body:text published:boolean ruby script/generate scaffold post title:string body:text published:boolean rake db:migrate rake cucumber All the tests are passing. Now I want to test using Javascript. At this time this is how scenario looks like Scenario: Delete post Given the following posts: |title|body|published| |title 1|body 1|false| |title 2|body 2|true| |title 3|body 3|false| |title 4|body 4|true| When I delete the 3rd post Then I should see the following posts: |Title|Body|Published| |title 1|body 1|false| |title 2|body 2|true| |title 4|body 4|true| I added @javascript at the top. Now when I run rake cucumber then I see a confirmation page. But nothing happens until I click. What do I need to do so that OK is clicked automatically and test proceeds ahead.

• Getting a 404 when setting up MVC in IIS 6 and using .NET 4 beta 2

  - by joshcomley

  Hi all, I've completed this set up on a fair few IIS 6 boxes, but one is giving me a tough time. The problem occurs when I add the application extension mapping to: c:\windows\microsoft.net\framework\v4.0.21006\aspnet_isapi.dll When this is in place, I get a 404 error on every request. Even if I remove all files from the application directory apart from a basic test.htm and navigate to that, I still get a 404. I've unchecked the "Verify that file exists" I've set up a .NET 4 application pool and pointed my application to that I've changed the ASP.NET version to 4.0.21006 I've checked the IIS log file, and there's nothing useful in there (it only shows the first bunch of requests after each reboot and then stops logging) I've checked the application event log and nothing gets reported I've installed MVC 2 I've copied the set up onto another box, just to be sure, following all the same steps - and it all works! What else can I look out for?? N.B: If I set .NET to v2 in IIS, then I can successfully navigate to \test.htm

• Loading fixtures in django unit tests

  - by loder

  I'm trying to start writing unit tests for django and I'm having some questions about fixtures: I made a fixture of my whole project db (not certain application) and I want to load it for each test, because it looks like loading only the fixture for certain app won't be enough. I'd like to have the fixture stored in /proj_folder/fixtures/proj_fixture.json. I've set the FIXTURE_DIRS = ('/fixtures/',) in my settings.py. Then in my testcase I'm trying fixtures = ['proj_fixture.json'] but my fixtures don't load. How can this be solved? How to add the place for searching fixtures? In general, is it ok to load the fixture for the whole test_db for each test in each app (if it's quite small)? Thanks!

• Problem sending mail with simple .net application. Server refusal error.

  - by Fatih

  I have a very simple .net application for testing SMTP on .net. But i am receiving this weird error. "System.Net.Mail.SmtpException: Failure sending mail. --- System.Net.WebException: Unable to connect to the remote server --- System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it" SMTP server is remote and doesn't need any kind of authentication so i don't need credentials. But i can send mails from this computer with outlook using same smtp server and same smtp settings without any problem. Any ideas? It will be appreciated so much. Imports System.Net.Mail Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim smtp As New SmtpClient smtp.Host = "10.241.128.220" smtp.Port = 25 smtp.Send("[email protected]", "[email protected]", "test", "test") End Sub

• How to mock protected virtual members with Rhino.Mocks?

  - by Vadim

  Moq allows developers to mock protected members. I was looking for the same functionality in Rhino.Mocks but fail to find it. Here's an example from Moq Quick Start page how to mock protected method. // at the top of the test fixture using Moq.Protected() // in the test var mock = new Mock<CommandBase>(); mock.Protected() .Setup<int>("Execute") .Returns(5); // if you need argument matching, you MUST use ItExpr rather than It // planning on improving this for vNext mock.Protected() .Setup<string>("Execute", ItExpr.IsAny<string>()) .Returns(true); Let me know if I'm chasing something that doesn't exit.

• Use Any() and Count() in Dynamic Linq

  - by ArpanDesai

  I am trying to write dynamic Linq Library query to fetch record on condition, Customers who has order count is greater than 3 and ShipVia field equal 2. Below is my syntax what i have tried. object[] objArr = new object[10]; objArr[0] = 1; IQueryable<Customer> test = db.Customers.Where("Orders.Count(ShipVia=2)", objArr); and IQueryable<Customer> test = db.Customers.Where("Orders.Any(ShipVia=2).Count()", objArr); But both are not working. In second query Any returns true so it won't work with Count. Suggest me a way to implement this.

• Can I have conditional construction of classes when using IoC.Resolve ?

  - by Corpsekicker

  I have a service class which has overloaded constructors. One constructor has 5 parameters and the other has 4. Before I call, var service = IoC.Resolve<IService>(); I want to do a test and based on the result of this test, resolve service using a specific constructor. In other words, bool testPassed = CheckCertainConditions(); if (testPassed) { //Resolve service using 5 paramater constructor } else { //Resolve service using 4 parameter constructor //If I use 5 parameter constructor under these conditions I will have epic fail. } Is there a way I can specify which one I want to use?

• Overriding LINQ extension methods

  - by Ruben Vermeersch

  Is there a way to override extension methods (provide a better implementation), without explicitly having to cast to them? I'm implementing a data type that is able to handle certain operations more efficiently than the default extension methods, but I'd like to keep the generality of IEnumerable. That way any IEnumerable can be passed, but when my class is passed in, it should be more efficient. As a toy example, consider the following: // Compile: dmcs -out:test.exe test.cs using System; namespace Test { public interface IBoat { void Float (); } public class NiceBoat : IBoat { public void Float () { Console.WriteLine ("NiceBoat floating!"); } } public class NicerBoat : IBoat { public void Float () { Console.WriteLine ("NicerBoat floating!"); } public void BlowHorn () { Console.WriteLine ("NicerBoat: TOOOOOT!"); } } public static class BoatExtensions { public static void BlowHorn (this IBoat boat) { Console.WriteLine ("Patched on horn for {0}: TWEET", boat.GetType().Name); } } public class TestApp { static void Main (string [] args) { IBoat niceboat = new NiceBoat (); IBoat nicerboat = new NicerBoat (); Console.WriteLine ("## Both should float:"); niceboat.Float (); nicerboat.Float (); // Output: // NiceBoat floating! // NicerBoat floating! Console.WriteLine (); Console.WriteLine ("## One has an awesome horn:"); niceboat.BlowHorn (); nicerboat.BlowHorn (); // Output: // Patched on horn for NiceBoat: TWEET // Patched on horn for NicerBoat: TWEET Console.WriteLine (); Console.WriteLine ("## That didn't work, but it does when we cast:"); (niceboat as NiceBoat).BlowHorn (); (nicerboat as NicerBoat).BlowHorn (); // Output: // Patched on horn for NiceBoat: TWEET // NicerBoat: TOOOOOT! Console.WriteLine (); Console.WriteLine ("## Problem is: I don't always know the type of the objects."); Console.WriteLine ("## How can I make it use the class objects when the are"); Console.WriteLine ("## implemented and extension methods when they are not,"); Console.WriteLine ("## without having to explicitely cast?"); } } } Is there a way to get the behavior from the second case, without explict casting? Can this problem be avoided?

• How can I properly use environment variables encoded as Windows-1251 in Perl?

  - by Kartlee

  I have an environment variable set in Windows as TEST=abc£ which uses Windows-1252 code page. Now, when I run a Perl program test.pl this environment value comes properly. When I call another Perl code - test2.pl from test1.pl either by system(..) or Win32::Process, the environment comes garbled. Can someone provide information why this could be and way to resolve it? The version of perl I am using is 5.8. If my understanding is right, perl internally uses utf-8, so the initial process - test1.pl received it right from Windows-1252 → utf-8. When we call another process, should we convert back to Windows-1252 code page?

• spoj: runlength

  - by user285825

  For RLM problem of SPOJ: This is the problem: "Run-length encoding of a number replaces a run of digits (that is, a sequence of consecutive equivalent digits) with the number of digits followed by the digit itself. For example, 44455 would become 3425 (three fours, two fives). Note that run-length encoding does not necessarily shorten the length of the data: 11 becomes 21, and 42 becomes 1412. If a number has more than nine consecutive digits of the same type, the encoding is done greedily: each run grabs as many digits as it can, so 111111111111111 is encoded as 9161. Implement an integer arithmetic calculator that takes operands and gives results in run-length format. You should support addition, subtraction, multiplication, and division. You won't have to divide by zero or deal with negative numbers. Input/Output The input will consist of several test cases, one per line. For each test case, compute the run-length mathematics expression and output the original expression and the result, as shown in the examples. The (decimal) representation of all operands and results will fit in signed 64-bit integers." These are my testcases: input: 11 + 11 988726 - 978625 12 * 41 1124 / 1112 13 * 33 15 / 16 19222317121013161815142715181017 + 10 10 + 19222317121013161815142715181017 19222317121013161815142715181017 / 19222317121013161815142715181017 19222317121013161815142715181017 / 11 11 / 19222317121013161815142715181017 19222317121013161815142715181017 / 12 12 / 19222317121013161815142715181017 19222317121013161815142715181017 / 141621161816101118141217131817191014 141621161816101118141217131817191014 / 19222317121013161815142715181017 19222317121013161815142715181017 / 141621161816101118141217131817191013 141621161816101118141217131817191013 / 19222317121013161815142715181017 19222317121013161815142715181017 * 11 11 * 19222317121013161815142715181017 19222317121013161815142715181017 * 10 10 * 19222317121013161815142715181017 19222317121013161815142715181017 -

• Install app on Motorola Backflip from AT&T

  - by eric

  I'm trying to test an app out on the Motorola Backflip with AT&T as the carrier. I checked USB debugging on the phone's Development screen. Using Eclipse, how do I get the app to load on the Backflip so I can test it? DDMS shows a device with a bunch of question marks and unkown. Seems that it only gives me the option to load the app on the SD card which doesn't do me any good. I searched and found a Motorola driver which I'm supposed to install to the adb folder. Where is that folder? I've checked the phone and on my development machine. Maybe I need new glasses?

• How to Maintain per-Client State in a WCF Service?

  - by tbischel

  I've created a WCF service in which I would like it to maintain state between calls from the client. I figured the easiest way to do this was to add this attribute to the service: [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] since this is supposed to keep a separate service alive for each client over the life of the client proxy (or timeout in the extreme case). I also added a test function that tracks a list of user inputs, and spits out a concatenated string with all the inputs over the life of the service. When I run this in the test client generated by visual studio, I find that the list I was using to hold past data is reset with each call. Is there something else I need to do to maintain state per session?

  I'm a new user of dynatree plugin. When I read the documentation, I found the list of tree and node class member functions, such as tree.getRoot(), node.countChildren(). However, when I tried to use them, it complained that no such methods were found. Here is a sample code I am testing with: var tree = ("#test").dynatree(treeData); var rootNode = tree.getRoot(); //not working var rootNode2 = ("#test").dynatree("getRoot"); //this works var numChildren = rootNode2.countChildren(); //not working Help please.

• Nullable ToString()

  - by StupidDeveloper

  I see everywhere constructions like: int? myVar = null; string test = myVar.HasValue ? myVar.Value.ToString() : string.Empty; Why not use simply: string test = myVar.ToString(); Isn't that exactly the same ? At least Reflector says that: public override string ToString() { if (!this.HasValue) { return ""; } return this.value.ToString(); } So, is that correct (the shorter version) or am I missing something?

• CSS Margins Increase with H1 Length

  - by Ethan Turkeltaub

  Consider the following markup: <!DOCTYPE html> <html> <head> <title>Test Page</title> <link href="screen.css" rel="stylesheet" /> </head> <body> <h1>Test</h1> <h3>Description</h3> </body> </html> And the CSS: h3{ margin-top: -25px; } Now, I want the H3 to have a margin-left of however long H1 is, and it is consistently 20px away. So, if I have a H1 block of 200px long, then H3 would have a margin-left of 220px, and so on and so forth. How would I do this?

• gcc precompiled headers weird behaviour with -c option

  - by pachanga

  Folks, I'm using gcc-4.4.1 on Linux and before trying precompiled headers in a really large project I decided to test them on simple program. They "kinda work" but I'm not happy with results and I'm sure there is something wrong about my setup. First of all, I wrote a simple program(main.cpp) to test if they work at all: #include <boost/bind.hpp> #include <boost/function.hpp> #include <boost/type_traits.hpp> int main() { return 0; } Then I created the precompiled headers file pre.h(in the same directory) as follows: #include <boost/bind.hpp> #include <boost/function.hpp> #include <boost/type_traits.hpp> ...and compiled it: $ g++ -I. pre.h (pre.h.gch was created) After that I measured compile time with and without precompiled headers: with pch $ time g++ -I. -include pre.h main.cpp real 0m0.128s user 0m0.088s sys 0m0.048s without pch $ time g++ -I. main.cpp real 0m0.838s user 0m0.784s sys 0m0.056s So far so good! Almost 7 times faster, that's impressive! Now let's try something more realistic. All my sources are built with -c option and for some reason I can't make pch play nicely with it. You can reproduce this with the following steps below... I created the test module foo.cpp as follows: #include <boost/bind.hpp> #include <boost/function.hpp> #include <boost/type_traits.hpp> int whatever() { return 0; } Here are the timings of my attempts to build the module foo.cpp with and without pch: with pch $ time g++ -I. -include pre.h -c foo.cpp real 0m0.357s user 0m0.348s sys 0m0.012s without pch $ time g++ -I. -c foo.cpp real 0m0.330s user 0m0.292s sys 0m0.044s That's quite strange, looks like there is no speed up at all!(I ran timings for several times). It turned out precompiled headers were not used at all in this case, I checked it with -H option(output of "g++ -I. -include pre.h -c foo.cpp -H" didn't list pre.h.gch at all). What am I doing wrong?

• input type text and onKeyDown not working under IE

  - by dygi

  Hi there. I am writing a WWW application, it has to run under IE. I have the problem with the code that runs under FF, but i can't get it running under IE. // JS code function test() { if (window.event.keyCpde == 13) window.location.href.ssign("myPage.php"); } I've tried some similar ways around window.location and location.href, also document.location. I've read that IE has problems with that, so i ask for a solution. The goal is, that page reloads after typing in some text into <input type='text' name='item_code' onKeyDown='test()'> and click enter. So the result is similar to pressing submit type button below the text input. Within IE it reloads the same page and nothing happens. In FF it correctly works.

• Flex URLRequest Timeout

  - by MooCow

  I have a Flex program that gets a JSON array from a PHP script. The PHP script doesn't contain just a simple JSON array but it grabs data from Activecollab and do some work on the data before encoding the data. The first test involve a small JSON array that took a short time to encode by PHP. However, when I try to scale up the test, the Flash movie will crash trying to load the JSON data from PHP. There's no code difference between the tests, just the amount of data and amount of time it takes PHP to encode. Am I looking at a memory problem or a time out problem? PS: When I call the PHP script in Firefox, it doesn't time out and still return a JSON array. It just took awhile to return the array.

• point light illumination using Phong model

  - by Myx

  Hello: I wish to render a scene that contains one box and a point light source using the Phong illumination scheme. The following are the relevant code snippets for my calculation: R3Rgb Phong(R3Scene *scene, R3Ray *ray, R3Intersection *intersection) { R3Rgb radiance; if(intersection->hit == 0) { radiance = scene->background; return radiance; } ... // obtain ambient term ... // this is zero for my test // obtain emissive term ... // this is also zero for my test // for each light in the scene, obtain calculate the diffuse and specular terms R3Rgb intensity_diffuse(0,0,0,1); R3Rgb intensity_specular(0,0,0,1); for(unsigned int i = 0; i < scene->lights.size(); i++) { R3Light *light = scene->Light(i); R3Rgb light_color = LightIntensity(scene->Light(i), intersection->position); R3Vector light_vector = -LightDirection(scene->Light(i), intersection->position); // check if the light is "behind" the surface normal if(normal.Dot(light_vector)<=0) continue; // calculate diffuse reflection if(!Kd.IsBlack()) intensity_diffuse += Kd*normal.Dot(light_vector)*light_color; if(Ks.IsBlack()) continue; // calculate specular reflection ... // this I believe to be irrelevant for the particular test I'm doing } radiance = intensity_diffuse; return radiance; } R3Rgb LightIntensity(R3Light *light, R3Point position) { R3Rgb light_intensity; double distance; double denominator; if(light->type != R3_DIRECTIONAL_LIGHT) { distance = (position-light->position).Length(); denominator = light->constant_attenuation + (light->linear_attenuation*distance) + (light->quadratic_attenuation*distance*distance); } switch(light->type) { ... case R3_POINT_LIGHT: light_intensity = light->color/denominator; break; ... } return light_intensity; } R3Vector LightDirection(R3Light *light, R3Point position) { R3Vector light_direction; switch(light->type) { ... case R3_POINT_LIGHT: light_direction = position - light->position; break; ... } light_direction.Normalize(); return light_direction; } I believe that the error must be somewhere in either LightDirection(...) or LightIntensity(...) functions because when I run my code using a directional light source, I obtain the desired rendered image (thus this leads me to believe that the Phong illumination equation is correct). Also, in Phong(...), when I computed the intensity_diffuse and while debugging, I divided light_color by 10, I was obtaining a resulting image that looked more like what I need. Am I calculating the light_color correctly? Thanks.

• Windows Azure Evolution - Web Sites (aka Antares) Part 1

  - by Shaun

  This is the 3rd post of my Windows Azure Evolution series, focus on the new features and enhancement which was alone with the Windows Azure Platform Upgrade June 2012, announced at the MEET Windows Azure event on 7th June. In the first post I introduced the new preview developer portal and how to works for the existing features such as cloud services, storages and SQL databases. In the second one I talked about the Windows Azure .NET SDK 1.7 on the latest Visual Studio 2012 RC on Windows 8. From this one I will begin to introduce some new features. Now let’s have a look on the first one of them, Windows Azure Web Sites.   Overview Windows Azure Web Sites (WAWS), as known as Antares, was a new feature still in preview stage in this upgrade. It allows people to quickly and easily deploy websites to a highly scalable cloud environment, uses the languages and open source apps of the choice then deploy such as FTP, Git and TFS. It also can be integrated with Windows Azure services like SQL Database, Caching, CDN and Storage easily. After read its introduction we may have a question: since we can deploy a website from both cloud service web role and web site, what’s the different between them? So, let’s have a quick compare.   CLOUD SERVICE WEB SITE OS Windows Server Windows Server Virtualization Windows Azure Virtual Machine Windows Azure Virtual Machine Host IIS IIS Platform ASP.NET WebForm, ASP.NET MVC, WCF ASP.NET WebForm, ASP.NET MVC, PHP Language C#, VB.NET C#, VB.NET, PHP Database SQL Database SQL Database, MySQL Architecture Multi layered, background worker, message queuing, etc.. Simple website with backend database. VS Project Windows Azure Cloud Service ASP.NET Web Form, ASP.NET MVC, etc.. Out-of-box Gallery (none) Drupal, DotNetNuke, WordPress, etc.. Deployment Package upload, Visual Studio publish FTP, Git, TFS, WebMatrix Compute Mode Dedicate VM Shared Across VMs, Dedicate VM Scale Scale up, scale out Scale up, scale out As you can see, there are many difference between the cloud service and web site, but the main point is that, the cloud service focus on those complex architecture web application. For example, if you want to build a website with frontend layer, middle business layer and data access layer, with some background worker process connected through the message queue, then you should better use cloud service, since it provides full control of your code and application. But if you just want to build a personal blog or a  business portal, then you can use the web site. Since the web site have many galleries, you can create them even without any coding and configuration. David Pallmann have an awesome figure explains the benefits between the could service, web site and virtual machine.   Create a Personal Blog in Web Site from Gallery As I mentioned above, one of the big feature in WAWS is to build a website from an existing gallery, which means we don’t need to coding and configure. What we need to do is open the windows azure developer portal and click the NEW button, select WEB SITE and FROM GALLERY. In the popping up windows there are many websites we can choose to use. For example, for personal blog there are Orchard CMS, WordPress; for CMS there are DotNetNuke, Drupal 7, mojoPortal. Let’s select WordPress and click the next button. The next step is to configure the web site. We will need to specify the DNS name and select the subscription and region. Since the WordPress uses MySQL as its backend database, we also need to create a MySQL database as well. Windows Azure Web Sites utilize ClearDB to host the MySQL databases. You cannot create a MySQL database directly from SQL Databases section. Finally, since we selected to create a new MySQL database we need to specify the database name and region in the last step. Also we need to accept the ClearDB’s terms as well. Then windows azure platform will download the WordPress codes and deploy the MySQL database and website. Then it will be ready to use. Select the website and click the BROWSE button, the WordPress administration page will be shown. After configured the WordPress here is my personal web blog on the cloud. It took me no more than 10 minutes to establish without any coding.   Monitor, Configure, Scale and Linked Resources Let’s click into the website I had just created in the portal and have a look on what we can do. In the website details page where are five sections. - Dashboard The overall information about this website, such as the basic usage status, public URL, compute mode, FTP address, subscription and links that we can specify the deployment credentials, TFS and Git publish setting, etc.. - Monitor Some status information such as the CPU usage, memory usage etc., errors, etc.. We can add more metrics by clicking the ADD METRICS button and the bottom as well. - Configure Here we can set the configurations of our website such as the .NET and PHP runtime version, diagnostics settings, application settings and the IIS default documents. - Scale This is something interesting. In WAWS there are two compute mode or called web site mode. One is “shared”, which means our website will be shared with other web sites in a group of windows azure virtual machines. Each web site have its own process (w3wp.exe) with some sandbox technology to isolate from others. When we need to scaling-out our web site in shared mode, we actually increased the working process count. Hence in shared mode we cannot specify the virtual machine size since they are shared across all web sites. This is a little bit different than the scaling mode of the cloud service (hosted service web role and worker role). The other mode called “dedicate”, which means our web site will use the whole windows azure virtual machine. This is the same hosting behavior as cloud service web role. In web role it will be deployed on the virtual machines we specified and all of them are only used by us. In web sites dedicate mode, it’s the same. In this mode when we scaling-out our web site we will use more virtual machines, and each of them will only host our own website. And we can specify the virtual machine size in this mode. In the developer portal we can select which mode we are using from the scale section. In shared mode we can only specify the instance count, but in dedicate mode we can specify the instance size as well as the instance count. - Linked Resource The MySQL database created alone with the creation of our WordPress web site is a linked resource. We can add more linked resources in this section.   Pricing For the web site itself, since this feature is in preview period if you are using shared mode, then you will get free up to 10 web sites. But if you are using dedicate mode, the price would be the virtual machines you are using. For example, if you are using dedicate and configured two middle size virtual machines then you will pay $230.40 per month. If there is SQL Database linked to your web site then they will be charged separately based on the Pay-As-You-Go price. For example a 1GB web edition database costs $9.99 per month. And the bandwidth will be charged as well. For example 10GB outbound data transfer costs $1.20 per month. For more information about the pricing please have a look at the windows azure pricing page.   Summary Windows Azure Web Sites gives us easier and quicker way to create, develop and deploy website to window azure platform. Comparing with the cloud service web role, the WAWS have many out-of-box gallery we can use directly. So if you just want to build a blog, CMS or business portal you don’t need to learn ASP.NET, you don’t need to learn how to configure DotNetNuke, you don’t need to learn how to prepare PHP and MySQL. By using WAWS gallery you can establish a website within 10 minutes without any lines of code. But in some cases we do need to code by ourselves. We may need to tweak the layout of our pages, or we may have a traditional ASP.NET or PHP web application which needed to migrated to the cloud. Besides the gallery WAWS also provides many features to download, upload code. It also provides the feature to integrate with some version control services such as TFS and Git. And it also provides the deploy approaches through FTP and Web Deploy. In the next post I will demonstrate how to use WebMatrix to download and modify the website, and how to use TFS and Git to deploy automatically one our code changes committed.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.
