• filtering search results with php

  - by fl3x7

  Hello, Cant really find any useful information on this through Google so hope someone here with some knowledge can help. I have a set of results which are pulled from a multi dimensional array. Currently the array key is the price of a product whilst the item contains another array which contains all the product details. key=>Item(name=>test, foo=>bar) So currently when I list the items I just order by the key, smallest first and it lists the products smallest price first. However I want to build on this so that when a user sees the results they can choose other ordering options like list all products by a name, certain manufacturer, colour, x ,y ,z etc etc from a drop down box(or something similar) This is where I need some guidance. Im just not sure how to go about it or best practise or anything. The only way I can think of is to order all the items by the nested array eg by the name, manufacturer etc. but how do I do that in PHP? Hope you understand what im trying to achieve(if not just ask). Any help on this with ideas, approaches or examples would be great. Thanks for reading p.s Im using PHP5

  - by 0xDEAD BEEF

  Hi guys! I have to get into Linux ASAP and realy mean ASAP. I have installed Cygwin but as allways - things dont go as easy as one would like. First problem i enconter was - i choose KDE package, but there is no sign of KDE files anywhere in cygwin folder. How do i run KDE windows. Currently startx fires, but all looks ugly! My desire is to download and run Qt Creator. Seems that there is no cygwin package, but downloading source and compiling is good to go. Only that i have forgoten every linux command i ever knew! :D Please - what are default commands u use on linux? What does exec do? what ./ stands for? What is directory strucutre and why there is such mess in bin folder? Thanks god - i have windows over cygwin, so downloading files is not a problem, but again -how do i unpack them in linux style and how to i build? simply issue "make" command from folder, where i extracted files? Please help!

• Good C string libary

  - by chamakits

  Hello all. I recently got inspired to start up a project I've been wanting to code for a while. I want to do it in C, because memory handling is key this application. I was searching around for a good implementation of strings in C, since I know me doing it myself could lead to some messy buffer overflows, and I expect to be dealing with a fairly big amount of strings. I found this article which gives details on each, but they each seem like they have a good amount of cons going for them (don't get me wrong, this article is EXTREMELY helpful, but it still worries me that even if I were to choose one of those, I wouldn't be using the best I can get). I also don't know how up to date the article is, hence my current plea. What I'm looking for is something that may hold a large amount of characters, and simplifies the process of searching through the string. If it allows me to tokenize the string in any way, even better. Also, it should have some pretty good I/O performance. Printing, and formatted printing isn't quite a top priority. I know I shouldn't expect a library to do all the work for me, but was just wandering if there was a well documented string function out there that could save me some time and some work. Any help is greatly appreciated. Thanks in advance! EDIT: I was asked about the license I prefer. Any sort of open source license will do, but preferably GPL (v2 or v3). EDIt2: I found betterString (bstring) library and it looks pretty good. Good documentation, small yet versatile amount of functions, and easy to mix with c strings. Anyone have any good or bad stories about it? The only downside I've read about it is that it lacks Unicode (again, read about this, haven't seen it face to face just yet), but everything else seems pretty good. EDIT3: Also, preferable that its pure C.

• How to use different providers for Linq to entities?

  - by Anders Svensson

  I'm trying to familiarize myself a bit more with database programming, and I'm looking at different ways of creating a data access layer for applications. I've tried out a few ways but there is such a jungle of different database technologies that I don't know what to learn. For instance I've tried using datasets with tableadapters. Using that I am able to switch data provider rather easily (by programming against the interfaces such as IDbConnection). This is one thing I would want to achieve. But I also know everyone's talking about LINQ, and I'm trying to get to know that a bit better too. So I have tried using Linq to Sql classes as the data access layer as well, but apparently this is not provider independent (works only for SQL Server). So then I read about the Entity Framework (which just as Linq to SQL apparently has gotten its share of bashing already...). It's supposed to be provider independent everybody says, but how? I tried out a tutorial to create an entity data model, but the only providers to choose from were SQL Server/Express. Just for learning purposes, I would like to know how to use the entity framework with MS Access/OleDb. Also, I would appreciate some input on what is the preferred database technology for data access. Is it LINQ still after all the bashing, or should you just use datasets because they are provider independent? Any pointers for what to learn would be great, because it's just too much to learn it all if I'm not going to use it in the end...!

• IE8 error when using dyanamic form actions

  - by user330711

  Hello all: Please go here to see an iframe based web app. Click on the map of Australia, choose a city, then buy some tickets. Now you will see the cart form located on the lower right corner. The problem is in IE8, I cannot delete checked rows from the table; whereas in other browsers such as FireFox3.6, Opera10, Safari4 and Chrome4, this action is all right. Below is the related javascript. It doesn't use jQuery, as part of the requirement is no framework allowed! And iframes are the my best bet, ajax will simply kill me under this restriction. /* cartForm.js */ function toDeleteRoutes() //this function is executed before form is to be submitted. { if(document.getElementsByClassName('delete_box').length > 0) //there're rows to delete { document.getElementById('cartForm').action ="./deleteRoutes.php"; document.getElementById('cartForm').target ="section4"; return true; //this enables the form to be submitted as usual. } else return false; //there is no more row in table to delete! } function toSendEmail() //this function is executed before form is to be submitted. { document.getElementById('cartForm').action ="./sendEmail.php"; document.getElementById('cartForm').target ="section3"; document.getElementById('delete_btn').disabled = true; //disable delete button now return true; //this enables the form to be submitted as usual. } function toCancelPurchase() { document.getElementById('cartForm').action ="./cancelPurchase.php"; document.getElementById('cartForm').target ="section4"; return true; //this enables the form to be submitted as usual. } I don't know which part is wrong, or this is just because IE8 screws all?

• jQuery only firing last class in multiple-class click

  - by user1134644

  I have a set of links like so: <a href="#internalLink1" class="classA">This has Class A</a> <a href="#internalLink2" class="classB">This has Class B</a> <a href="#internalLink3" class="classA classB">This has Class A and Class B</a> And here's the corresponding jQuery: $('.classA').click(function(){ // do class A stuff }); $('.classB').click(function(){ // do class B stuff }); Currently, when I click on the first link with Class A, it does the Class A stuff like it's supposed to. Similarly, when I click on the second link with Class B, it does the Class B stuff like it's supposed to. No worries there. My issue is, when I click on the third link with BOTH classes, it only fires the function for whichever class comes last (in this case, class B. If I put class A at the end instead, it performs class A's function). I want it to fire both. What am I doing wrong? Thanks in advance. EDIT: To those posting fiddles, nearly all of them work, so as many have said, it's most likely not my code, but the way it displays in my file. For a little more clarification, I was teaching myself some jQuery and decided to try making a (very) simple "Choose Your Own Adventure" type game. Here's a jsfiddle containing the opening of my bare-bones-please-don't-laugh game. Click on "Hide in the bushes", then "Examine the victim", then "Take any valuables and leave, he's dead already" <-- THIS is where the issue is. It's supposed to add 98 gold ("hawks") to your inventory, AND tell you that your alignment has shifted 1 point towards Chaotic. At the moment, it only does the chaotic alert, and no gold gets added to your inventory. The other option (refresh the fiddle to restart) that adds money to your inventory, but DOES NOT make you chaotic, works just fine (if you select "Search him for identification" instead of "take the money and run") Sorry this is so long!

• android nested lists

  - by Raogrimm

  i'm new to programming android and i have found some useful things for my app, but i can't seem to find how to make a list filled with an string array display a new list that is going to be populated with a string array. i would like to have the user choose an item from the top_menu list and from there go to the desired area and have that array appear. this is what i have so far: public class HelloListActivity extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); String[] top_menu = getResources().getStringArray(R.array.top_menu); setListAdapter(new ArrayAdapter<String>(this, R.layout.list_item, top_menu)); ListView lv = getListView(); lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { ??? } }); } all my arrays are working fine, i just don't know how to repopulate a new list with the other array depending on the choice the user made. any help is greatly appreciated

• PHP download script for "processes running limited" hosting (eg. hostgator)

  - by Joe

  I am currently with HostGator on a shared hosting plan. I have a new website I'm trying to setup with a download.php script. The issue I am having is that, while someone is "downloading" a file through the download.php script, it counts as a "process" and my hosting plan limits the processes that can be running at the same time to 25 at present. My question is, what options do I have? a). Move to new web hosting that doesn't limit processes running. b). Change the way files are downloaded. I would like to choose option b), however it occurs to me that I need to have the file accessed through PHP in order to restrict the number of downloads and to track download statistics, as well as protecting against hotlinking. If there was a way to have the PHP script send them the file so that the process doesn't need to be running the whole time the file is being downloaded, I would eliminate the problem, however to my knowledge that isn't possible. Should I make the move to a new hosting company? I really enjoy HostGator as they have provided the best hosting experience for me thus far, except for this one issue of course, so I don't want to go on the hunt for another decent shared hosting company that doesn't limit processes running, only to find out there is another restriction or "catch" to the shared hosting deal.

• Implementing comparision operators via 'tuple' and 'tie', a good idea?

  - by Xeo

  (Note: tuple and tie can be taken from Boost or C++11.) When writing small structs with only two elements, I sometimes tend to choose a std::pair, as all important stuff is already done for that datatype, like operator< for strict-weak-ordering. The downsides though are the pretty much useless variable names. Even if I myself created that typedef, I won't remember 2 days later what first and what second exactly was, especially if they are both of the same type. This gets even worse for more than two members, as nesting pairs pretty much sucks. The other option for that is a tuple, either from Boost or C++11, but that doesn't really look any nicer and clearer. So I go back to writing the structs myself, including any needed comparision operators. Since especially the operator< can be quite cumbersome, I thought of circumventing this whole mess by just relying on the operations defined for tuple: Example of operator<, e.g. for strict-weak-ordering: bool operator<(MyStruct const& lhs, MyStruct const& rhs){ return std::tie(lhs.one_member, lhs.another, lhs.yet_more) < std::tie(rhs.one_member, rhs.another, rhs.yet_more); } (tie makes a tuple of T& references from the passed arguments.) Edit: The suggestion from @DeadMG to privately inherit from tuple isn't a bad one, but it got quite some drawbacks: If the operators are free-standing (possibly friends), I need to inherit publicly With casting, my functions / operators (operator= specifically) can be easily bypassed With the tie solution, I can leave out certain members if they don't matter for the ordering Are there any drawbacks in this implementation that I need to consider?

• What constitutes explicit creation of entities in LINQ to SQL? What elegant "solutions" are there to

  - by Marcelo Zabani

  Hi SO, I've been having problems with the rather famous "Explicit construction of entity type '##' in query is not allowed." error. Now, for what I understand, this exists because if explicit construction of these objects were allowed, tracking changes to the database would be very complicated. So I ask: What constitutes the explicit creation of these objects? In other terms: Why can I do this: Product foo = new Product(); foo.productName = "Something"; But can't do this: var bar = (from item in myDataContext.Products select new Product { productName = item.productName }).ToList(); I think that when running the LINQ query, some kind of association is made between the objects selected and the table rows retrieved (and this is why newing a Product in the first snippet of code is no problem at all, because no associations were made). I, however, would like to understand this a little more in depth (and this is my first question to you, that is: what is the difference from one snippet of code to another). Now, I've heard of a few ways to attack this problem: 1) The creation of a class that inherits the linq class (or one that has the same properties) 2) Selecting anonymous objects And this leads me to my second question: If you chose one of the the two approaches above, which one did you choose and why? What other problems did your approach introduce? Are there any other approaches?

• slidepanel/hover help

  - by Josh

  I'm trying to create a menu navigation system from the top of the page. I want it so when I hover over the link, it drops down (the link drops down; so it'd be as if there was a whole field being hidden beyond the 0px mark) with the related field. I've gotten it to work, somehow but it still isn't right. A few issues are: when I hover over .drop_slide and then if I choose to close it by hovering back over the .drop_slide it does as it's told, which is "slide, slide". I'm interested in rectifying this issue so it doesn't do that, however I just don't know how. The idea is to have multiple links in the .slide, so I need it to be constantly open while the user mouses over the other links. Should this be created in one field? If so, how would I do that with a drop down in mind? Am I approaching this completely wrong? Lol. Should I be researching into .animate? I've been looking at it actually, but I can't get anything to grow negatively. Say; marginTop: -85px or something. ANY help is appreciated, thanks! $(document).ready(function(){ function slide() { $("#panel").slideToggle("slow"); } $(".drop_slide").hover(slide, stop); $("#panel").hover(stop, slide); });

• Set attribute disabled to options NOT containing a certain string

  - by kuswantin

  I know this should be easier if I could only use optgroups. But I am trying to avoid hacking core of my CMS, so jQuery should come to rescue again, hopefully. I have a select with options in a hierarchy sometimes, and I want to put attributes disabled to any of options containing text NOT starting with a dash. I want to code like: Set disabled attributes to selectors with options text NOT starting with a dash ("-"). <select id="options"> <option value="" selected="selected">- Please choose -</option> <option value="1">Parent1</option> <option value="2">-child1</option> <option value="3">-child2</option> <option value="4">-child3</option> <option value="5">-child4</option> <option value="6">Parent2</option> <option value="7">-child5</option> <option value="8">-child6</option> <option value="9">-child7</option> <option value="10">-child8</option> </select> The closest solution is here http://stackoverflow.com/questions/2012299/contain-start-by, $.extend($.expr[':'], { startsWith: function(elem,match) { return (elem.textContent || elem.innerText || "").indexOf(match[3]) == 0; } }); But I can't seem to do it right this far. Any help would be very much appreciated. Thank you very much.

• std::bind overload resolution

  The following code works fine #include <functional> using namespace std; using namespace std::placeholders; class A { int operator()( int i, int j ) { return i - j; } }; A a; auto aBind = bind( &A::operator(), ref(a), _2, _1 ); This does not #include <functional> using namespace std; using namespace std::placeholders; class A { int operator()( int i, int j ) { return i - j; } int operator()( int i ) { return -i; } }; A a; auto aBind = bind( &A::operator(), ref(a), _2, _1 ); I have tried playing around with the syntax to try and explicitly resolve which function I want in the code that does not work without luck so far. How do I write the bind line in order to choose the call that takes the two integer arguments?

• C++: how serialize/deserialize objects without any library?

  - by Winte Winte

  I try to understand how serializing/deserializing works in c++, so I want to do that without any libs. But I really stuck with that. I start with simple objects but when I try to deserilize a vector I understand that I can't get a vector without if I don't write it size before. Moreover, I don't know which format of file I should choose because if digits will be existed before size of vector I haven't chance to read it right. However it is only the vector but I also want to do that with classes and map container. My task is serialize/deserialize a objects as this: PersonInfo { unsigned int age_; string name_; enum { undef, man, woman } sex_; } Person : PersonInfo { vector<Person> children_; map<string, PersonInfo> addrBook_; } Currently I know how to serialize simple objects in way as this: vector<PersonInfo> vecPersonInfo; vecPersonInfo.push_back(*personInfo); vecPersonInfo.push_back(*oneMorePersonInfo); ofstream file("file", ios::out | ios::binary); if (!file) { cout<<"can not open file"; } else { vector<PersonInfo>::const_iterator iterator = vecPersonInfo.begin(); for (; iterator != vecPersonInfo.end(); iterator++) { file<<*iterator; } Could you please suggest how I can do this for this conplex object or a good tutorial that explain it clearly?

• SDK2 query for counting: which is more efficient?

  - by user1195996

  I have an app that is displaying metrics about defects in a project. I have the option of making one query that returns all the defects, and from that I can break out about four different metrics (How many defects escaped QA in 90 days, 180 days, and then the same metrics again but only counting sev1/sev2 defects). I could make four queries and limit the results to one so that I just get a count for each. Or I could make one query that encompass them all (all defects that escaped QA in 180 days) and then count up the difference. I'm figuring worst case, the number of defects that escaped QA in the last six months will generally be less than 100, certainly less 500 worst case. Which would you do-- four queryies with one result each, or one single query that on average might return 50, perhaps worst case 500? And I guess the key question is-- where are the inflections points? Perhaps I have more metrics tomorrow (who knows, 8?) and a different average defect counts. Is there a rule of thumb I could use to help choose which approach?

• MVC and Checkboxes...leaves a bit to be desired

  - by Josh

  Here is my problem. I have a list of models that are displayed to the user. On the left is a checkbox for each model to indicate that the user wants to choose this model (in this case, we're building products a user can add to their shopping cart). The model has no concept of being chosen...it strictly has information about the product in question. I've talked with a few other developers after having gone through and the best I could come up with is getting the formcollection and string parsing the key values to determine whether the checkbox is checked or not. This doesn't seem ideal. I was thinking there would be something more strongly bound, but I can't figure out a way to do it. I tried creating another model that had a boolean property to represent being checked and a property of the model and passing a list of that model type to the view and creating a ActionResult on the controller that accepts a list of the new model / checked property, but it comes back null. Am I just thinking too much like web forms and should just continue on with parsing checkbox values?

• SQL Server: Why use shorter VARCHAR(n) fields?

  - by chryss

  It is frequently advised to choose database field sizes to be as narrow as possible. I am wondering to what degree this applies to SQL Server 2005 VARCHAR columns: Storing 10-letter English words in a VARCHAR(255) field will not take up more storage than in a VARCHAR(10) field. Are there other reasons to restrict the size of VARCHAR fields to stick as closely as possible to the size of the data? I'm thinking of Performance: Is there an advantage to using a smaller n when selecting, filtering and sorting on the data? Memory, including on the application side (C++)? Style/validation: How important do you consider restricting colunm size to force non-sensical data imports to fail (such as 200-character surnames)? Anything else? Background: I help data integrators with the design of data flows into a database-backed system. They have to use an API that restricts their choice of data types. For character data, only VARCHAR(n) with n <= 255 is available; CHAR, NCHAR, NVARCHAR and TEXT are not. We're trying to lay down some "good practices" rules, and the question has come up if there is a real detriment to using VARCHAR(255) even for data where real maximum sizes will never exceed 30 bytes or so. Typical data volumes for one table are 1-10 Mio records with up to 150 attributes. Query performance (SELECT, with frequently extensive WHERE clauses) and application-side retrieval performance are paramount.

• How to make cakePHP retreive the data represented by a foreign key?

  - by XL

  Greetings cake experts, I have a question that I think would really help a lot of people getting started with cakePHP. I have a feeling it will be easy for some of you, but it is quite challenging to me. I have a simple database with multiple tables. I can't figure out how to make cakePHP display the values associated with a foreign key in an index view. Or create a view where the fields of my choice (the ones that make sense to users like location name - not location_id can be updated or viewed on a single page). I have created an example at http://lovecats.cakeapp.com that illustrate the question. If you look at the page and click the "list cats", you will notice that it shows the location_id field from the locations table. You will also notice that when you click "add cats", you must choose a location_id from the locations table. This is the automagic way that cakePHP builds the app. I want this to be the field location_name. The database is setup so that the table cats has a foreign key called location_id that has a relationship to a table called locations. This is my problem: I want these pages to display the location_name instead of the location_id. If you want to login to the application, you can go to http://cakeapp.com/sqldesigners/sql/lovecats and the password 'password' to look at the db relationships, etc. How do I have a page that shows the fields that I want? And is it possible to create a page that updates fields from all of the tables at once? This is the slice of cake that I have been trying to figure out and this would REALLY get me over a hump. You can download the app and sql from the above url.

• yet another logic.

  - by Sunil

  I'm working on a research problem out of curiosity and I don't know how to program the logic that I've in mind. Let me explain it to you : I've 4 vectors say for example, v1 = 1 1 1 1 v2 = 2 2 2 2 v3 = 3 3 3 3 v4 = 4 4 4 4 Now what I want to do is to add them combination-wise. i.e v12 = v1+v2 v13 = v1+v3 v14 = v1+v4 v23 = v2+v3 v24 = v2+v4 v34 = v3+v4 Till this step it is just fine. The problem/trick is now, at the end of each iteration I give the obtained vectors into a black box function and it returns only few of the vectors say v12, v13 and v34. Now, I want to add each of these vectors one vector from v1,v2,v3,v4 which it hasn't added before. For example v3 and v4 hasn't been added to v12 so I want to create v123 and v124. similarly for all the vectors like, v12 should become : v123 = v12+v3 v124 = v12+v4 v13 should become : v132 // this should not occur because I already have v123 v134 = v13+v4; v14,v23 and v24 cannot be considered because it was deleted in the black box function so all we have in our hands to work with is v12,v13 and v34. v34 should become : v341 // cannot occur because we have 134 v342 = v34+v2 It is important that I do not do all at one step at the start like for example I can do (4 choose 3) 4C3 and finish it off but I want to do it step by step at each iteration. I've asked a modified version of this question before (without including the black box function) and got answers here. Can anybody tell me how to do it when the black box function is included ? A modification of the previous answer would also be great. Thanks in advance.

• What are advantages of using a one-to-one table relationship? (MySQL)

  - by byronh

  What are advantages of using a one-to-one table relationship as opposed to simply storing all the data in one table? I understand and make use of one-to-many, many-to-one, and many-to-many all the time, but implementing a one-to-one relationship seems like a tedious and unnecessary task, especially if you use naming conventions for relating (php) objects to database tables. I couldn't find anything on the net or on this site that could supply a good real-world example of a one-to-one relationship. At first I thought it might be logical to separate 'users', for example, into two tables, one containing public information like an 'about me' for profile pages and one containing private information such as login/password, etc. But why go through all the trouble of using unnecessary JOINS when you can just choose which fields to select from that table anyway? If I'm displaying the user's profile page, obviously I would only SELECT id,username,email,aboutme etc. and not the fields containing their private info. Anyone care to enlighten me with some real-world examples of one-to-one relationships?

  I'm writing a program that is supposed to take in a list of names from the user, store them in an array, and then search through the list to check and see if the next name the user enters is part of the original list of names. The issue I'm having is that when I go to enter a list of names, it only saves the last name entered into the list. I've searched the web and this site for similar issues, but I can't seem to find anything that answers this issue specifically. Here is the part of code where I have problem void initialize(char names[][],const int MAX_NAMES,const int MAX_NAMELENGTH) { int i,Number_entrys; printf("How many names would you like to enter to the list?"); scanf("%d",&Number_entrys); if(Number_entrys>MAX_NAMES){ printf("Please choose a smaller entry"); }else{ for (i=0; i<Number_entrys;i++){ scanf("%s",names); } } printf("%s",names); } trying very hard to teach myself, so be gentle lol.

• Silverlight 4 Released

  - by ScottGu

  The final release of Silverlight 4 is now available. What is in the Silverlight 4 Release Silverlight 4 contains a ton of new features and capabilities.  In particular we focused on three scenarios with this release: Further enhancing media support Building great business applications Enabling out of the browser experiences On Tuesday I gave a 60 minute keynote about Silverlight 4 which showed off many of the new features and capabilities now available.  You can watch my keynote to learn more about Silverlight 4 and see a ton of great demos of it in action. Also check out these three great posts by Tim Heuer that talk about the new features and provide a guide to the new Silverlight 4 capabilities: Silverlight 4 Beta – A Guide to the New Features Silverlight 4 RC – What was updated Silverlight 4 Released Also read David Anson’s great Silverlight 4 Toolkit post to learn more about the new controls and functionality also available within the Silverlight Toolkit release we also made available today.  Also visit this page to learn more about the new Pivot functionality in Silverlight 4 – which makes it really easy to visualize and interact with collections of images using Silverlight. Lastly – make sure to visit the www.silverlight.net web-site and visit the “Get Started” section to find free tutorials that you can use. Download and Install Silverlight 4 Tools for VS 2010 To develop Silverlight 4 applications you should first download and install Visual Studio 2010 or download and install the free Visual Web Developer 2010 Express edition. Then install the Silverlight Tools RC2 for Visual Studio 2010.  This setup includes the Silverlight 4 Developer Runtime, Silverlight 4 SDK, RIA Services, and VS 2010 tools support.  Once installed you can do File->New Project and choose Silverlight Application to create your first Silverlight 4 project.  You can then use the new WYSIWYG Silverlight designer in Visual Studio 2010 to design and build rich Silverlight 4 applications. Important: If you previously installed the Silverlight 4 Beta or RC build on your machine, please make sure to go into Add/Remove programs and uninstall the “Update for Visual Studio 2010 (KB976272)” package prior to installing the Silverlight Tools RC2 for Visual Studio 2010 setup.  Note that while Silverlight 4 is released, the “Silverlight 4 Tools for VS 2010” is currently in “RC2” mode (meaning we are going to keep an eye out for any remaining issues before finally calling it done).  We’ll update the tools to be “final” in a few weeks once we verify that no last minute issues/bugs remain. Download and Install Expression Blend 4 Release Candidate You can also download and install the Expression Blend 4 RC to create and design great Silverlight 4 applications.  Blend contains “Sketchflow” support – which makes it really easy to rapidly prototype ideas and applications.  To learn more about Sketchflow watch this 90 second video of it in action. Summary Today’s release is the fourth release of Silverlight that we’ve shipped in the last 2.5 years.  The team has done a great job of advancing it quickly and staying focused.  We think today’s Silverlight 4 release opens up a ton of new opportunities to build great solutions for both consumers and business scenarios.  We are looking forward to seeing what you build with it! Hope this helps, Scott
