• What are good resources for computer graphics basics?

  - by Hanno Fietz

  During Flex programming, I recently ran into several questions (about box models, ways to join lines and misaligning pixels [on doctype]) regarding computer graphics and layout, where I felt that I lacked some basic background on things like concepts like the box model approaches mapping real numbers to a pixel raster (like font anti-aliasing) conventions found across drawing engines, like do you count y coordinates from top or bottom, and why I feel that reading some basic Wikipedia articles, books or tutorials on these subjects might help in phrasing my questions more specifically and debugging my code more systematically. I have repeatedly found myself writing tiny test apps in Flex, just to find out how the APIs do very basic stuff. My assumption would be that if I knew the right vocabulary and some general concepts, I could solve these questions much faster.

• How does the VS XAML designer know what to auto-populate certain values with?

  - by Pwninstein

  <Button Name="MyButton" Content="Test" FontStyle="Italic" /> In the above XAML definition of a button, the FontStyle property is set to Italic. The designer is somehow able to populate a list for me to choose from when I hit the = sign. How is this achieved? Before you answer, consider that the FontStyle property is, appropriately enough, of type FontStyle (which is a struct). It's not an enumeration, which would be trivial for VS to list out at design time, so how are the valid list of options chosen to be displayed? There is also a completely separate FontStyles class which contains three static fields, Italic, Normal, and Oblique which just so happen to be the three items VS provides in the drop down list. Is there some mapping going on behind the scenes between the FontStyle struct and FontStyles class, because I've looked in many places in both the object browser and in .NET Reflector and couldn't determine anything from either. Thanks!! I NEED to know!* *Not really, but it would be nice to :)

• Java Hibernate Lazy=false

  - by Noor

  When setting Lazy=false, then hibernate will automatically loads the objects into the required sets e.g. <set name="Options" table="ATTRIBUTEOPTION" inverse="false" cascade="all" lazy="false"> <key> <column name="ATTRIBUTEID" /> </key> <one-to-many class="com.BiddingSystem.Models.AttributeOption" /> </set> but if in my xml mapping, I place lazy=true and in some place in my application i decide that i want to load all attribute options, should i do it manually, or is there a technique which lets tells hibernate that now i want to set lazy=false??

• Error 3032 during EF 4.0 validation

  - by Mohammadreza

  Hi guys. I have a table that has a column called "rowguid" with default value of newguid(). After I delete the generated property in the Entity Framework 4.0 designer, whenever I try to build or validate the model I receive the following error message. Error 3023: Problem in mapping fragments starting at line 1460:Column People.rowguid in table People must be mapped: It has no default value and is not nullable. It's an obvious error message but the problem is that the column HAS default value. Does anyone knows what the problem is? Thanks.

• Usual hibernate performance pitfall

  - by Antoine Claval

  Hi, We have just finish to profile our application. ( she's begin to be slow ). the problem seems to be "in hibernate". It's a legacy mapping. Who work's, and do it's job. The relational shema behind is ok too. But some request are slow as hell. So, we would appreciate any input on common and usual mistake made with hibernate who end up with slow response. Exemple : Eager in place of Lazy can change dramaticly the response time....

• Insert record into mysql db with Entity Framework

  - by sanfra1983

  Hi, the problem is that it will insert a new record in a mysql table, I have already done the mapping of the mysql db and I have already done tests returning data and everything works. Now I read from a file, where there are queries written, I have them run me back and the result of true or false based on the final outcome of single query written to the file. Txt; I did this: using (var w = new demotestEntities ()) ( foreach (var l listaqueri) ( var p = we.CreateQuery <category> (l); we.SaveChanges (); result = true; ) ) but it does not work, I sense that it returns no errors, but neither the result given written in the query. txt file is as follows: INSERT INTO category (id, name) VALUES (null, 'test2') anyone can help me?

• URL Routing to Default Page

  - by ewitkows

  Hi everyone, I have an asp.net 4.0 web forms app setup with url rereouting. In development, my app's URL looks perfect. I have a page called enrollnow.aspx that responds to the routing, so if I type in localhost/enrollnow/abc, my app responds as expected. Once promoted into my staging environment however, the URL is off. I have a domain, and a virtual dir created off of my domain called "enrollnow". So basically, my URL outside of development is: mydomain.com/enrollnow/enrollnow/abc - where the first enrollnow is the directory, the second enrollnow is the page name, and the abc is my route value. Is there any way I can have the "default page" respond, so the second enrollnow (which is enrollnow.asp) isnt required? Perhaps I can rename my enrollnow.aspx page to default.aspx, or I can change the mapping in my routetable? Heres my routetable, incase that helps. thanks! Routetable: RouteTable.Routes.Add("PURLRoute", New Route("EnrollNow/{PURL_ID}", New PageRouteHandler("~/EnrollNow.aspx")))

• Need to get pixel averages of a vector sitting on a bitmap...

  - by user346511

  I'm currently involved in a hardware project where I am mapping triangular shaped LED to traditional bitmap images. I'd like to overlay a triangle vector onto an image and get the average pixel data within the bounds of that vector. However, I'm unfamiliar with the math needed to calculate this. Does anyone have an algorithm or a link that could send me in the right direction? I'm not even clear what this type of math is called. I've created a basic image of what I'm trying to capture here: http://imgur.com/Isjip.gif

• Mixing JPA annotations and XML configuration

  - by HDave

  I have a fairly large (new) project in which we have annotated many domain classes with JPA mappings. Now it is time to implement many named queries -- some entities may have as many as 15-20 named queries. I am thinking that writing these named queries in annotations will clutter the source files and therefore am considering putting these in XML mapping files. Is this possible? Mort importantly, is this reasonable? Are there better approaches? How is this done?

• Creating a view linking three different node types with two node references

  - by mikesir87

  I have the following content types: Camp - the top level type Registration Information - contains node reference to Camp called Camp Medical Release Form - contains node reference to registration information called Camper I would like to create a View that takes the nid for the Camp, and pulls out all the fields for the Registration Info and Medical Release Form. I'm having trouble figuring out how to set up the various arguments/relationships. I haven't done something that's referenced more than two types. I know it would be smart/best to just combine the Registration Info and Medical Release Form, since it's a 1:1 mapping, but we can't. So... any help would be appreciated!

• htaccess: how to prevent infinite subdirectories?

  - by Vincent Isles

  My .htaccess at the root directory contains this: Options -MultiViews +FollowSymlinks -Indexes ErrorDocument 404 /404.htm RewriteEngine On RewriteBase / followed by a bunch of RewriteRules. The .htaccess at the /forum subdirectory contains this: RewriteEngine On RewriteBase /forum RewriteRule ^index.html$ index.php [L,NE] RewriteRule ^(.*)-t-([0-9]+).html(.*)$ showthread.php?tid=$2$3 [QSA,L] RewriteRule ^(.*)-t-([0-9]+)-([0-9]+).html$ showthread.php?tid=$2&page=$3 [QSA,L] followed by other rules mapping SEO-friendly URLs to the true URLs. mydomain.com/forum/a-thread-t-1.html returns the page showthread.php?tid=1 but so does mydomain.com/forum/forum/a-thread-t-1.html, mydomain.com/forum/forum/forum/a-thread-t-1.html and so on. I don't want this behavior - I want pages accessed as /forum/forum/* to return a 404. Any hint on where I had been wrong?

• Getting .NET schema for a stored procedure result

  - by PHeiberg

  I have a couple of stored procedures in T-SQL where each stored procedure has a fixed schema for the result set. I need to map the result sets for each procedure to a POCO object and need the column name and type for each column in the result set. Is there a quick way of accessing the information? The best way I have found so far is accessing each stored procedure from .NET and writing my own extension method on a IDataReader/IDataRecord for dumping the information (column names and types) out. Example, a stored procedure executing the following query: SELECT Id, IntField, NullableIntField, VarcharField, DateField FROM SomeTable would require me to have the mapping information: Id - Guid IntField - System.Int32 NullableIntField - Nullable<System.Int32> VarcharField - String DateField - DateTime

• Maintaining the position of columns in Grails/GORM

  - by firnnauriel

  Is there a way to fix the position of the columns in a domain? I have this domain: class SnbrActVector { int nid String term double weight static mapping = { version false id(generator: 'assigned') } static constraints = { nid(blank:false) term(blank:false) weight(blank:false) } } This is the schema of the table generated: CREATE TABLE `fractor_grailsDEV`.`snbr_act_vector` ( `id` bigint(20) NOT NULL, `weight` double NOT NULL, `term` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `nid` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci It seems that the order of the columns were reversed. Is there a way to make it like this? (order is nid, term, weight) CREATE TABLE `fractor_grailsDEV`.`snbr_act_vector` ( `id` bigint(20) NOT NULL, `nid` int(11) NOT NULL, `term` varchar(255) COLLATE utf8_unicode_ci NOT NULL, `weight` double NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

• Unity setting problem when defined in code

  - by Xabatcha

  I have problem when asking for default ILogger from Unity container. I have this setting defined in code (its VB.net) Dim container As IUnityContainer ... container.RegisterType(Of ILogger, NullLogger)() container.RegisterType(Of ILogger, EntLibLogger)("EL") When I am getting ILogger from container I may have different name, like: Ioc.Resolve(Of ILogger)("MyLogger") However this raises error as the mapping is not set for 'MyLogger'. Can I force container to return type which was registered without name? Actually when I used setting from web.config it worked. Any tips most welcome. Thanks. Cheers, X.

• ASP.net MVC support for URL's with hyphens

  - by John

  Is there an easy way to get the MvcRouteHandler to convert all hyphens in the action and controller sections of an incoming URL to underscores as hyphens are not supported in method or class names. This would be so that I could support such structures as sample.com/test-page/edit-details mapping to Action edit_details and Controller test_pagecontroller while continuing to use MapRoute method. I understand I can specify an action name attribute and support hyphens in controller names which out manually adding routes to achieve this however I am looking for an automated way so save errors when adding new controllers and actions.

• IIS browse directory problem on a virtual directory

  - by user335518

  I have two differents virtual directories mapping to the same directory on the OS. In one of this virtual directories I need to have the browse folders disable, and in the other one I need to have it enable. The problem is that when I changed one of them the other change as well. I thinks this problem is related that both virtual directories points to the same folder in the OS, but with the IIS6 I had this same configuration with out a problem. Any idea of a work around with this? Thanks!

• Looking for a list of free data api's and web services

  - by darren

  I'm wondering if anybody has come across a comprehensive list of free sources for data (as a web api) or web services. I'm looking to start a new project to tinker with in my spare time and I am wondering what interesting data is available to play with. It seems like many api services such as last.fm or google search don't exist or are no longer free. Possible examples of what I am looking for information about a given ip address mapping api's information about books, movies, music information about places, businesses, attractions meteorological, financial or other scientific data shopping, products I would appreciate any suggestions you may have about interesting data freely available through the web. thanks

• geom_rect and NULL

  - by csgillespie

  I've been looking at the geom_rect example in section 5.10 of the ggplot2 book and don't understand the purpose of the NULL's in the aes function. For example, using the mpg data: g = ggplot(data=mpg, aes(x=displ, y=hwy)) + geom_point() #Produces a plot with a transparent filled region g + geom_rect(aes(NULL, NULL), alpha=0.1,xmin=5, xmax=7, ymin=10, ymax=45, fill="blue") #Solid filled region (v0.9) or nothing in v0.8 g + geom_rect(alpha=0.1,xmin=5, xmax=7, ymin=10, ymax=45, fill="blue") My understanding is that the NULL's are resetting the x & y mapping, but I don't see why this should affect the transparency.

• In SQL How do I copy values from one table to another based on another field's value?

  - by Joshua1729

  Okay I have two tables VOUCHERT with the following fields ACTIVATIONCODE SERIALNUMBER VOUCHERDATADBID UNAVAILABLEAT UNAVAILABLEOPERATORDBID AVAILABLEAT AVAILABLEOPERATORDBID ACTIVATIONCODENEW EXT1 EXT2 EXT3 DENOMINATION -- I added this column into the table. and the second table is VOUCHERDATAT with the following fields VOUCHERDATADBID BATCHID VALUE CURRENCY VOUCHERGROUP EXPIRYDATE AGENT EXT1 EXT2 EXT3 What I want to do is copy the corresponding VALUE from VOUCHERDATAT and put it into DENOMINATION of VOUCHERT. The linking between the two is VOUCHERDATADBID. How do I go about it? It is not a 1:1 mapping. What I mean is there may be 1000 SERIALNUMBERS with a same VOUCHERDATADBID. And that VOUCHERDATADBID has only entry in VOUCHERDATAT, hence one value. Therefore, all serial numbers belonging to a certain VOUCHERDATADBID will have the same value. Will JOINS work? What type of JOIN should I use? Or is UPDATE table the way to go? Thanks for the help !!

• In grails how to insert additional parameters (from session) in all url's

  - by HeDinges

  I would like to add an additional parameter in my url, the use case is the following: When user do their login they also specify a 'company' name and from that moment on, all urls should map to: /$company/$controller/$action/$id The main idea is to have the current company name available in all url's, have it bookmarkable, and not to have to pass the company name everywhere as a request parameter. Also, once users are logged in it is acceptable to have the chosen company name in session scope. What is the right way of inserting this parameter in all our urls? I tried to modify my UrlMappings mapping, but I didn't found a way to insert the company name. Thanks,

• Simplest one-to-many Map case in Hibernate doesn't work in MySQL

  - by Malvolio

  I think this is pretty much the simplest case for mapping a Map (that is, an associative array) of entities. @Entity @AccessType("field") class Member { @Id protected long id; @OneToMany(cascade = CascadeType.ALL, fetch=FetchType.LAZY) @MapKey(name = "name") private Map<String, Preferences> preferences = new HashMap<String, Preferences>(); } @Entity @AccessType("field") class Preferences { @ManyToOne Member member; @Column String name; @Column String value; } This looks like it should work, and it does, in HSQL. In MySQL, there are two problems: First, it insists that there be a table called Members_Preferences, as if this were a many-to-many relationship. Second, it just doesn't work: since it never populates Members_Preferences, it never retrieves the Preferences. [My theory is, since I only use HSQL in memory-mode, it automatically creates Members_Preferences and never really has to retrieve the preferences map. In any case, either Hibernate has a huge bug in it or I'm doing something wrong.]

• Random access view in boost::multi_array

  - by linai

  Here is a boost example: typedef boost::multi_array<double, 1> array_type; typedef array_type::index index; array_type A(boost::extents[100]); for(index i = 0; i != A.size(); ++i) { A[i] = (double)i; } // creating view array_type::index_gen indices; typedef boost::multi_array_types::index_range range; array_type::array_view<1>::type myview = A[ indices[range(0,50)] ]; What this code does is creating a subarray or view mapping onto the original array. This view is continuous and covers from 0th to 50th elements of an original array. What if I need to explicitly define elements I'd like to see in the view? How can I create a view with indices like [1, 5, 35, 23] ? Any ideas?

• Entity Framework model and foreign key property

  - by verror

  I have 2 tables that I import to EF model. First table has a property [section] that acts as foreign key to the second table. When I map this property in model to the table and try to compile I get this error: Problem in Mapping Fragments starting at lines 158, 174: Non-Primary-Key column(s) [Section] are being mapped in both fragments to different conceptual side properties - data inconsistency is possible because the corresponding conceptual side properties can be independently modified. If i remove this property from the model it passes, but when I query the data I don't have the section field. I know that I can get it by using the navigation field and reading this property from the second table, but to make it work I must include the other table in my query. var res = from name in Context.Table1.Include("Table2")... Why do I need to include the association just for one field?
