  • Query to select from two different tables

    - by ryan
    I would like to select from two tables and display my result using this query: CREATE TABLE Buy_Table ( buy_id int identity primary key, user_id int, amount decimal (18,2) ); go INSERT INTO Buy_Table (user_id, amount) VALUES ('1', 10), ('1', 8), ('1', 20), ('3', 1), ('2', 2); go CREATE TABLE Sell_Table ( sell_id int identity primary key, user_id int, amount decimal (18,2) ); go INSERT INTO Sell_Table (user_id, amount) VALUES ('1', 10), ('1', 8), ('1', 20), ('3', 3), ('2', 3); go select [user_id], 'Buy' as [Type], buy_id as [ID], amount from Buy_Table union all select [user_id], 'Sell', sell_id, amount from Sell_Table order by [user_id], [ID], [Type] However the above query will return each row of the user_id like this I want to display my result to something like this in a grid: Can this be done in query itself rather manipulating the grid? Thx

  • Android ArrayList Calendar add and get is different

    - by Raku ShinShou
    I put increment date of the calendar and add into arraylist, but when i loop them out, the date is all same. Calendar a = Calendar.getInstance(); ArrayList<Calendar> b = new ArrayList<Calendar>(); for (int i=0; i<3; i++) { a.add(Calendar.DATE, i>0 ? 1 : 0); b.add(a); } for (int i=0; i<b.size(); i++){ Log.d("xxx", "test=" + b.get(i)); } suppose i wan 10/11/2012, 11/11/2012, 12/11/2012 but it come out like 12/11/2012, 12/11/2012, 12/11/2012 Anyone know how to solve this?

  • [jquery] Different function for same class on 'click' / 'dblclick'

    - by Shishant
    Hello, This are my two functions, on single click it works fine, but on dblclick both functions execute, any idea? I tried using live instead of delegate but still both functions execute on dblclick // Change Status on click $(".todoBox").delegate("li", "click", function() { var id = $(this).attr("id"); $.ajax({ //ajax stuff }); return false; }); // Double Click to Delete $(".todoBox").delegate("li", "dblclick", function(){ var id = $(this).attr("id"); $.ajax({ //ajax stuff }); return false; });

  • How can I tweak this A* search pathfinding algorithm to handle different terrain movement values?

    - by user422318
    I'm creating a 2D map-based action game with similar interaction design as Diablo II. In other words, the player clicks around a map to move their player. I just finished player movement and am moving on to pathfinding. In the game, enemies should charge the player's character. There are also five different terrain types that give different movement bonuses. I want the AI to take advantage of these terrain bonuses as they try to reach the player. I was told to check out the A* search algorithm (http://en.wikipedia.org/wiki/A*_search_algorithm). I'm doing this game in HTML5 and JavaScript, and found a version in JavaScript: http://www.briangrinstead.com/blog/astar-search-algorithm-in-javascript I'm trying to figure out how to tweak it though. Below are my ideas about what I need to change. What else do I need to worry about? When I create a graph, I will need to initialize the 2D array I pass in passed on with a traversal of a map that corresponds to the different terrain types. in graph.js: "GraphNodeType" definition needs to be modified to handle the 5 terrain types. There will be no walls. in astar.js: The g and h scoring will need to be modified. How should I do this? in astar.js: isWall() should probably be removed. My game doesn't have walls. in astar.js: I'm not sure what this is. I think it indicates a node that isn't valid to be processed. When would this happen, though? At a high level, how do I change this algorithm from "oh, is there a wall there?" to "will this terrain get me to the player faster than the terrain around me?" Because of time, I'm also debating reusing my Bresenham algorithm for the enemies. Unfortunately, the different terrain movement bonuses won't be used by the AI, which will make the game suck. :/ I'd really like to have this in for the prototype, but I'm not a developer by trade nor am I a computer scientist. :D If you know of any code that does what I'm looking for, please share! Sanity check tips for this are also appreciated.

  • How do I backup my Ubuntu 9.10 system and then restore it to a new machine with different hardware?

    - by EricJLN
    I have a nicely configured Ubuntu 9.10 machine, with crossover linux (from Codeweavers) installed. I have the Nvidia drivers installed. Everything is just as I want it. Now I want to move to a new machine with different hardware: different sized hard drive, different size RAM, different video card, etc. I tried the technique suggested on Ubuntu forums, "Howto: Backup and restore your system!". The results: New system complains about swap not being found New system complains about not finding Nvidia hardware, and I can't open the System-Administration-Hardware Drivers application (i.e., /usr/bin/jockey-gtk) to fix the problem. As result of nvidia, X-Windows is throwing errors, and the on screen process for fixing X-Windows isn't working. How do I restore a backup of my old system, including my Crossover Linux installation, to a new machine with different hardware installed?

  • Why does modx-based site start using different domains for some content?

    - by naxa
    situation I have a modx site on a VPS with multiple domain and subdomain names. The modx site should use what I call the 'primary' domain name's 'primary' subdomain, ie www.intendedname.tld . The problem is that as time pass, the site mysteriously starts using another subdomain for links to content like videos, images, and even pages and (internal) links. The other subdomains doesn't serve this content of course. If I clear the modx cache, the original state is restored. However, the problem comes back again later. The VPS has a domain registered and multiple A records pointing to the VPS's IP, as subdomains. There is the 'primary' whan which is intended to be used as the public content server, the other ones are like docs. and test., etc. On top of that, I have dynamic-dns service client installed from no-ip on the machine and a dynamic domain-name bound. It gives a completely different domain name. I originally used it for ssh login and to serve a completely different site. An nginx server is put into good use to do rewrite the different subdomains to the right places. edit The modx templates use Templates use <base href="[[++site_url]]" />. current attempt to fix The current 'solution' to the problem is to also use the rewrite to rewrite everything to the 'primary' domain and subdomain. In the nginx config file for the site, it utilizes (unsurprisingly) the rewrite directive to rewrite the unexpected server_name entries (ie. the other subdomains) in a server block dedicated to this task. So with this, the main site basically works (sort of) but this renders all the other functions (docs) useless. Before this rewrite was set, the 'solution' was to clear the modx cache on a regular basis. The original modx content is not getting corrupted, only the files in cache are. What can I do to find out what actual the problem is and fix it?

  • Is there a name for a testing method where you compare a set of very different designs?

    - by DVK
    "A/B testing" is defined as "a method of marketing testing by which a baseline control sample is compared to a variety of single-variable test samples in order to improve response rates". The point here, of course, is to know which small single-variable changes are more optimal, with the goal of finding the local optimum. However, one can also envision a somewhat related but different scenario for testing the response rate of major re-designs: take a baseline control design, take one or more completely different designs, and run test samples on those redesigns to compare response rates. As a practical but contrived example, imagine testing a set of designs for the same website, one being minimalist "googly" design, one being cluttered "Amazony" design, and one being an artsy "designy" design (e.g. maximum use of design elements unlike Google but minimal simultaneously presented information, like Google but unlike Amazon) Is there an official name for such testing? It's definitely not A/B testing, since the main component of it (finding local optimum by testing single-variable small changes that can be attributed to response shift) is not present. This is more about trying to compare a set of local optimums, and compare to see which one works better as a global optimum. It's not a multivriable, A/B/N or any other such testing since you don't really have specific variables that can be attributed, just different designs.

  • Title of the page in search results and title of google's cached version are different. Why?

    - by Azmorf
    Check this: http://www.google.com/search?q=site:gunlawsbystate.com+kansas+gun+laws The title of the first result is "Kansas Gun Laws - Gun Laws By State". Although, on the page google has cached the title is different: <title>Kansas Gun Laws - Kansas Gun Law - Reciprocity Guide</title> Google shows the title that has been on the site 2-3 months ago. Google bot has visited the website a lot of times since that, and as you see it even cached it (the latest version is of 15th Sept), however for some reason it doesn't change the title to the new one in the search results. We use hash-bang URL structure on this website. It completely meets google's requirements for AJAX websites (_escaped_fragment_ stuff). The issue I explained is happening with almost all hash-bang pages that got indexed. Questions: Why does it keep old page title in the search results? Can it be connected to the fact that I'm using hash-bang URLs? There are lots of pages on the site that have the same issue, all of them have hash-bang URLs. Another thing I noticed is that Google's "Preview" feature doesn't work for any hash-bang URLs on the site. Did I do anything wrong? It has got cached versions of the pages, why wouldn't it generate a preview? Thanks (and sorry for my English) PS. Here's a weird thing I also noticed: this search query https://www.google.com/search?q=Kansas+Gun+Laws+-+Reciprocity+Guide shows the correct title for the same page as in the example above. Why does google show different titles for the same page when you run different queries?

  • Why are Awstats, Webalizer, and Google Analytics results so different?

    - by Matt
    I realize that comparing Awstats and Webalizer to Google Analytics is like comparing apples to oranges, but each of them track at least basic statistics about visitors and pages. So why are there often very significant differences in their data? For example, comparing Analytics with Awstats using some numbers from a small site over the past week: Awstats 78 unique visitors 205 visits (2.62 visits/visitor) 1,072 pages (5.22 pages/visit) Google Analytics 115 unique visitors 240 visits (2.08 visits/visitor) 1,275 pages (5.31 pages/visit) They're similar on the number of visits, but page views and uniques are quite different. I'm familiar with discrepancies of a much higher magnitude on some larger sites, showing that this trend scales proportionally upward. What is the reason behind the different numbers, even when the data is quite trivial like unique visitors and page loads?

  • How can I test different TV display types for my XBLIG game?

    - by Steve Dunn
    The XBLIG submission check-list says to ensure that all important stuff critical to game-play be visible in the 'TitleSafeArea'. I've received a bug report during play-test of my game (Crazy Balloon Lite) that says parts of my scrolling 2D map are only half visible (i.e. chopped at the left of the screen). I've tested my game myself on a 47" TV and also a 19" VGA monitor, both of which look fine. The bug report says the issue occurs on a standard 20" TV. My question is: without buying different sizes of TVs, is there a way to test what my game will look like on different sized displays?

  • Why does Java allow to implement different interfaces, each containing a method with the same signature?

    - by Software Engeneering Learner
    I've recently found that I can have two interfaces containing method with the same signature as a method in the other interface. And then I can have an interface or class that implements both of that interfaces. So the descendant class/interface has implicitly implements two different methods as a one method. Why is this allowed in Java? I can see a numerous problems that arises from that. Even eclipse only can find out about implementations for only one interface method, but for the second one it doesn't show any implementations at all. Also I believe there would be problems with automatic refactoring, like when you would like to change the signature of the method in one of the interfaces and IDE won't be able to correctly change that signature in all implementations, as they implement two different interfaces and how will IDE know what interface method it implementation descends. Why don't just make a compiler error like 'interfaces method names clashes' or something like that?

  • Is it a good practice to use branches to maintain different editions of the same software?

    - by Tamás Szelei
    We have a product that has a few different editions. The differences are minor: different strings here and there, very little additional logic in one, very little difference in logic in the other. When the software is being developed, most changes need to be added to each edition; however, there are a few that don't and a few that needs to differ. Is it a valid use of branches if I have release-editionA and release-editionB (..etc) branches? Are there any gotchas? Good practices? Update: Thanks for the insight everyone, lots of good answers here. The general consensus seems to be that it is a bad idea to use branches for this purpose. For anyone wondering, my final solution to the problem is to externalize strings as configuration, and externalize the differing logic as plugins or scripts.

  • What are the different ways to texture a terrain?

    - by ApocKalipsS
    I'm working with XNA on a 3D Game, and I'm trying to have a proper and nice environnement. I actually followed a tutorial to create a terrain from a Heightmap, and to texture it, I just apply a grass texture on it and tile it a number of times. But what I want to do is to have a really realistic texturing, but also generate it automatically (for example if I want to use a perlin noise to generate a terrain and then texture it). I already learnt about multi-texturing, loading a map file with different colors for different textures, but I don't think this is really efficient, for instance for cliffs or very steep areas it will tile a texture badly as it's a view from the top. Also I don't know how i'll draw roads or dirt paths with that. I hope you understood me despite my english! If you don't, basically, here what I want to do: How do I texture a randomly generated terrain? :) Thank you for your answers!

  • Is there any guarantee about the graphical output of different GPUs in DirectX?

    - by cloudraven
    Let's say that I run the same game in two different computers with different GPUs. If for example they are both certified for DirectX 10. Is there a guarantee that the output for a given program (game) is going to be the same regardless the manufacturer or model of the GPU? I am assuming the configurable settings are exactly the same in both cases. I heard that it is not the case for DirectX 9 and older, but that it is true for DirectX 10. If someone could provide a source confirming or denying it, it would be great. Also what is the guarantee offered. Will the output be exactly the same or just perceptually the same to the human eye?

  • Get and set accessors do they protect different instances of a variable?

    - by Chris Halcrow
    The standard method of implementing get and set accessors in C# and VB.NET is to use a public property to set and retrieve the value of a corresponding private variable. Am I right in saying that this has no effect of different instances of a variable? By this I mean, if there are different instantiations of an object, then those instances and their properties are completely independent right? So I think my understanding is correct that setting a private variable is just a construct to be able to implement the get and set pattern? Never been 100% sure about this.

  • How do I move (copy) my entire Ubuntu system to a different hard disk?

    - by boywithaxe
    The HDD I have my Ubuntu installed is about to fail. I would rather not lose 3 years worth of data, customisation and apps. I am looking for a way to move the complete system (SWAP included, because I'm not sure if I can relink the system to a new SWAP partition) to another HDD. But not the complete HDD< only the partition containing Ubuntu, to a partition on a different HDD. Basically I'd like to do what I've been able to do with Norton Ghost for my Windows install. I thought about using Clonezilla but I think I would have issues with GRUB (Especially trying to boot from a different UUID than what is in the conf file). do you know of any way this could be done? PS, my home directory is encrypted but that's not really an issue, because I can work around that. EDIT: changed the explanation to make it clearer

  • Most standard / Best way to keep the same top menu among different web pages?

    - by jsoldi
    What's the standard way to keep the same menu on top among different web pages without having to duplicate it on each page (I don't mean that it doesn't reload like when using frames and only loading the bottom part; I want the menu to scroll with the page when scrolling down, like this, this, this and pretty much every single web page that exists). I found this answer but the guy can't use Php and I can. Plus, I see several people giving different suggestions, but I assume there is a standard since pretty much every single web page in the whole web have a menu on top that stays the same among multiple pages . I'm just a newbie on web design (I can program Php and Html easily but I have no idea about standards and stuff like that since I'm self-taught guy ;)). What I would normally do is to include the menu with php but I'm not sure if this is the "standard".

  • How can I play different sounds each time I startup?

    - by user82171
    I have read questions on Changing startup sound in Ubuntu and Changing startup music in Ubuntu. I understand how to rename 'desktop-login.ogg' and copy the sound I want as 'desktop-login.ogg'. My question is - is there a way I can play different sounds each time I login? It may sound silly, but if possible I would like to play different sounds. I am guessing that this may be perhaps possible by running some kind of script which replaces/renames the desktop-login.ogg file each time I shutdown, so that a new file is ready to be played on the next startup. But I don't know how to copy a new file from a particular folder to desktop-login.ogg upon each shutdown, nor do I know where the script should reside. I would appreciate it if someone could tell me how to do it, or if there is an easier way of doing this. Thank you

  • Making Separate Assemblies For Different Types Of Tests For The Same Component?

    - by sooprise
    I was told by a few members here that splitting up my unit tests into different assemblies for different components is the best way to structure unit tests. Now, I have a few questions about that idea. What are the advantages of this? Organization, and isolation of errors? Let's say I have a component named "calculator", and I create an assembly for the unit tests on "calculator". Would I create a separate assembly for the integration tests I want to run on "calculator"? Or is the definition of an integration test a test across multiple components, like "calculator" and whatever else, which would require a separate assembly to test both of them together? In that case, would I have one assembly to do all of the integration testing for every component combination?

  • is it possible for a router to provide different gateway?

    - by Hao
    i have tp-link wireless router 192.168.10.188, i was can make it function as DHCP provider(range 192.168.10.100 to 192.168.10.109). the only thing that i cannot make it work as intended, is for it to provide different gateway (192.168.10.1), the computers that obtain IP from that router properly get everything(dynamic IP and dns IP), but there is no function on that router to provide different gateway, the computers always get the router's address(192.168.10.188) as gateway. is there a router that can provide different gateway other than its own address? or the question should be, is the dhcp of a router can provide different gateway other than its own address? note: i cannot make the wireless router address as 192.168.10.1, we have main router(non-wireless, address is 192.168.10.1) that is connected directly to internet

  • Word 2010 header "different first page" option does not work if you select the same built-in header preset?

    - by fredsbend
    I have a three page Word 2010 document. I have set a header on the first page and marked the "different first page" option to make the follow page headers different. It works as expected so long as I don't select the same built-in header preset for the following pages. Here's what I am doing: Check mark different first page. Make the header for the first page using Alphabet preset. Attempt to make the header for the following pages by starting with the same Alphabet preset. I only want to change the text of the following headers but still want the same graphical effects. Click off the header into the body of the document. Upon doing this the headers on the first page are updated to the ones I just made for the following pages. I don't I am doing something wrong because I can choose a different header preset and it will work as expected. If I select the same preset, however, it updates all headers, whether the "different on first page" is selected or not. If this is repeatable on others' computers the I would say it's a word bug. If not then please help me figure out how to get this working right.

  • Ask the Readers: Would You Be Willing to Give Windows Up and Use a Different O.S.?

    - by Asian Angel
    When it comes to computers, Windows definitely rules the desktop in comparison to other operating systems. What we would like to know this week is if you would actually be willing to give up using Windows altogether and move to a different operating system on your computers. Note: This week’s Ask the Readers post is posing a hypothetical situation, so please refrain from starting arguments or a flame war in the comments. Good reasoned discussion is always welcome. There is no doubt that Windows is the dominant operating system in use today. Everywhere you go or look it is easy to find computers with Windows installed such as at work, home, the library, government offices, and more. For many people it is the operating system that they know and are comfortable with, which makes changing to a different operating system less appealing. Adding to the preference for Windows (or dependency based on your view) is the custom software that many businesses use on a daily basis. Throw in the high volume of people who depend on and use Microsoft Office as a standard for their business documents and it is little wonder that Windows is so dominant. So what would you use if you did decide to take a break from or permanently move away from Windows? If your choice is Linux then you have a large and wonderful variety of distributions to choose from based on what you want out of your system. Want a distribution that is easy to work with? You could choose Ubuntu, Linux Mint, or others that are engineered to be ready to go “out of the box”. Like a challenge? Perhaps Arch Linux is more your style. One of the most attractive features of all about Linux is the price…it is very hard to beat free! Maybe Mac OS X sounds like the perfect choice. It has a certain mystique and elegance associated with it and many OS X fans refuse to use anything else if given a choice. Then there is the soon to be released Chrome OS with its’ emphasis on cloud computing. This is a system that is definitely focused on being as low-maintenance and hassle-free as possible. Quick on, quick off, minimalist, and made to be portable. All of the system’s updates will occur automatically leaving you free to work and play in the cloud. But it does have its’ limitations…no installing all of those custom apps that you love using on Windows or other systems…it is literally all about the browsing window and web apps. So there you have it. If the opportunity presented itself would you, could you give Windows up and use a different operating system? Would it be easy or hard for you to do? Perhaps it would not really matter so long as you could do what you needed or wanted to do on a computer. And maybe this is the perfect time to try something new and find out…that new favorite operating system could be just an install disc away. Let us know your thoughts in the comments!
