  • VS2010 Clean Web.configs - not updating

    - by cw
    Hello, I'm messing around with MVC 2.0 on VS2010 and am having an issue getting the clean web config feature working. Basically in my Web.debug.config I have <connectionStrings xdt:Transform="Replace"> <add name="ApplicationServices" connectionString="Server=localhost;Database=SITE_DB;User ID=dbuser;Password=P@ssw0rd;Trusted_Connection=False;" /> </connectionStrings> and in my Web.config I have <connectionStrings> <add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" /> </connectionStrings> When I run the site in debug mode, I'd expect that xdt:Transform="Replace" would replace the entire connectionStrings section with what is in the Web.debug.config. Am I assuming wrong? Or am I doing something else incorrect. Not much info posted around this and I'd figure I'd ask you guys.

  • Why did this work? ( php dot notation )

    - by Daniel
    Hi, I was writing some php code after a long sint doing ruby and I accidently wrote this: [root@ip-10-160-47-98 test]# cat run.php <?php class MyTest { public function run() { var_dump(this.test); } } $object = new MyTest(); $object->run(); [root@ip-10-160-47-98 test]# php run.php string(8) "thistest" [root@ip-10-160-47-98 test]# Now, this.test should have been $this-test, but the compiler was actually happy to let this run. Does anyone know how (this.test) got converted into a string "thistest"? Compiled and run on php 5.3.2 amazon instance ami-e32273a6 (CentOS 5.4) -daniel

  • Testing complex entities

    - by Carlos
    I've got a C# form, with various controls on it. The form controls an ongoing process, and there are many, many aspects that need to be right for the program to run correctly. Each part can be unit tested (for instance, loading some coefficients, drawing some diagnostics) but I often run into problems that are best described with an example: "If I click here, then here, then change this, then re-open the form, then click here, it crashes or produces an error" I've tried my best to use common code organisational ideas (inheritance, DRY, separation of concerns) but there never seems to be a way to test every single path, and inevitably, a form with several controls will have a huge number of ways to execute. What can I read (preferably online) that addresses this kind of issue, and is there a (non-generic) term for it. This isn't a specific problem I'm having, but one that creeps up on me, especially with WinForms.

  • Grails pattern to reuse template on error

    - by bsreekanth
    Hello, I have a gsp template, where the data for create view is passed through the controller. def create = { def bookInstance = new Book() bookInstance .properties = params def map = getDefaultValues() render(template: "create", model: [bookInstance : bookInstance , title: map.title, somelist: somelist ....]) the gsp template <g:select optionKey="id" from="${somelist}" name="somelist.id" value="${bookInstance ?.somelist?.id}" noSelection="['null': '']"></g:select> now, in the save method, if there is an error, it returns currently populated and validated instance (default scaffold implementation) render(template: "create", model: [bookInstance : bookInstance ]) But the fields in the gsp (error page rendered from save action) is empty. I could see the reason as it looks the value in "${somelist}" , but it is not used in save method. Do i just need to check for null in the gsp and use whichever map is available, or any better method (passing all the map in the save method is not an option) .. thanks in advance..

  • What is the best approach to binding commands in a ViewModel to elements in the View?

    - by Micah
    Anyone who has tried to implement RoutedCommands in WPF using M-V-VM has undoubtedly run into issues. Commands (non-UI commands that is) should be implemented in the ViewModel. For instance if I needed to save a CustomerViewModel then I would implement that as a command directly on my CustomerViewModel. However if I wanted to pop up a window to show the users addresses I would implement a ShowCustomerAddress command directly in the view since this a UI specific function. How do I define the command bindings in the viewmodel, and use them in the view?

  • Query Concatenated Field (using SubSonic)

    - by jwynveen
    Is there a way to query against a concatenated field using MS SQL? For instance, what I want to do is something like: Select FirstName+' '+LastName as FullName from Attendees where FullName like '%Joe Schmoe%' The above doesn't work. What I have found works is: Select * from Attendee where FirstName+' '+LastName like '%Joe Schmoe%' but I can't figure out how to do that using a SubSonic SqlQuery. I have a number of joins and OR statements added dynamically that I don't want to have to write out the sql manually. Any help/ideas?

  • JPA entitymanager remove operation is not performant

    - by Samuel
    When I try to do an entityManager.remove(instance) the underlying JPA provider issues a separate delete operation on each of the GroupUser entity. I feel this is not right from a performance perspective, since if a Group has 1000 users there will be 1001 calls issued to delete the entire group and itr groupuser entity. Would it make more sense to write a named query to remove all entries in groupuser table (e.g. delete from group_user where group_id=?), so I would have to make just 2 calls to delete the group. @Entity @Table(name = "tbl_group") public class Group { @OneToMany(mappedBy = "group", cascade = CascadeType.ALL, fetch = FetchType.LAZY) @Cascade(value = DELETE_ORPHAN) private Set<GroupUser> groupUsers = new HashSet<GroupUser>(0);

  • How to tell Eclipse 3.4 WTP to not restart tomcat on JSP save?

    - by Boden
    Whenever I save a JSP file in my WTP project, Eclipse restarts its Tomcat instance. This is sorta driving me nuts. I don't want to disable auto reload completely, I just don't want it to happen when I save a file that doesn't require a restart. I'm not sure how Eclipse WTP works in this regard. Could it be my project structure? The JSP files are in WEB-INF/jsp. (this SO question is similar to mine, but doesn't have a sufficient answer) EDIT: I want auto-reloading to happen, but not for file saves that do not require it. When I save a JSP there is no reason to have Tomcat restart. Thus what I'm looking for, if possible, is a smarter way for reloading to happen.

  • How to dynamically load & unload a TinyMCE Plugin

    - by Matt Simpson
    Does anyone know if there is a way I can dynamically load and unload a TinyMCE plugin after TinyMCE has already been loaded? Specifically, I'm thinking about asking the user whether or not they wish to load the fullpage plugin using perhaps a radio button or something above TinyMCE: <input type="radio" name="fullpage" value="enabled" /> Enable Fullpage Plugin<br /> <input type="radio" name="fullpage" value="disabled" /> Disable Fullpage Plugin<br /> <textarea name="tinymce" id="tinymce">...</textarea> I suppose I could destroy the original instance and load a new config (one for enabled / one for disabled), but it seems as though there should be a more elegant way of loading and unloading plugins.

  • Getting Image size of JPEG from its binary

    - by rajeshsr
    Hi I have a lot of jpeg files with varying image size. For instance, here is the first 640 bytes as given by hexdump of an image of size 256*384(pixels): 0000000: ffd8 ffe0 0010 4a46 4946 0001 0101 0048 ......JFIF.....H 0000010: 0048 0000 ffdb 0043 0003 0202 0302 0203 .H.....C........ 0000020: 0303 0304 0303 0405 0805 0504 0405 0a07 ................ 0000030: 0706 080c 0a0c 0c0b 0a0b 0b0d 0e12 100d ................

  • VB.NET function that takes other functions as a parameter, and executes them

    - by rob
    Hello, Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object. As I am calling these, it seems like it should be able to be factored better. For instance, everytime I call any of these functions, I want to test the return value for a session drop, and do something to try and reconnect to the remote system, etc. Using .net 3.5 Thanks! -R

  • ASP.NET error when trying to configure ListView + SqlDatasource for a MySql Table

    - by stighy
    Hi, i'm using ASP.NET + a MySql Db. I'm trying to configure a ListView so i've written: <asp:SqlDataSource ID="dsDatiUtente" runat="server" ConnectionString="Server=12.28.136.29;Database=mydb;Uid=m111d1;Pwd=fake;Pooling=false;" ProviderName="MySql.Data.MySqlClient" SelectCommand="SELECT * FROM user WHERE idUser=@IdUser" / At the beginning of my aspx page i've added <%@ Import Namespace="MySql.Data.MySqlClient" %> But if i click to the sqldatasource and click "Refresh Schema" i got this error: "Unable to retrive schema.... Unable to find the requested .Net Framework data provider" For instance, i've installed it , but i've also uninstalled old version, then installed new versions. In my project i simple copy Mysql dll into "bin" folder, then add a reference to that dll. I'm not sure is the corrected way... I need to have the "refreshed schema" to permit vs.net to build automatically my listview ... if i can't to "auto build" listview, i have to write all code by hand, and it is a too expensive work me :( What i'm wrong ? Thank you!

  • Numeric comparison difficulty in R

    - by Matt Parker
    I'm trying to compare two numbers in R as a part of a if-statement condition: (a-b) >= 0.5 In this particular instance, a = 0.58 and b = 0.08... and yet (a-b) >= 0.5 is false. I'm aware of the dangers of using == for exact number comparisons, and this seems related: (a - b) == 0.5) is false, while all.equal((a - b), 0.5) is true. The only solution I can think of is to have two conditions: (a-b) > 0.5 | all.equal((a-b), 0.5). This works, but is that really the only solution? Should I just swear off of the = family of comparison operators forever?

  • Regex to validate SMTP Responses?

    - by Alix Axel
    I'm writing a regular expression that can interactively validate SMTP responses codes, once the SMTP dialog is completed it should pass the following regex (some parentheses added for better readability): ^(220)(250){3,}(354)(250)(221)$ Or with(out) authentication: ^(220)(250)((334){2}(235))?(250){2,}(354)(250)(221)$ I'm trying to do rewrite the above regexes so that I can interactively check if the dialog is going as expected, otherwise politely send a QUIT command and close the connection saving bandwidth and time, but I'm having a hard time writing an optimal regex. So far I've managed to come up with: ^(220(250(334(235(250(354(250(221)?)?)?){0,})?){0,2})?)?$ Which, besides only matching authenticated connections, has some bugs... For instance, it matches: 220250334235250354250221 220250334334235250354250221 I've also tried the following modification: ^(220(250)?)?((334(235)?){2})?(250(354(250(221)?)?)?){0,}$ This one accepts non-authenticated responses but it fails to match 220250334 and wrongly matches 220250334334235250354250221 (at least 2 250 are needed before the 354 response code). Can someone help me out with this? Thanks in advance.

  • MS-Access nested DIR - check if a file exists elsewhere whilst looping through a folder

    - by David Carle
    I have used the DIR() command in Microsoft Access 2003 to loop through the files in folder A. This works fine, but I need to check if each file also exists in another location (folder B), and only process the file if it doesn't exist in folder B. The problem is that checking for the file existing in folder B also uses the DIR() function and this then resets or confuses the original one, with the result that no further files are found in folder A. Is there a way to check if a file exists without using DIR? Or, is there a way to have a separate instance of DIR? I suppose I could build a list of the files in folder A into an array and then process the entries in the array, but this seems rather 'clunky' Any suggestions for a better solution? Thanks

  • UINavigationController and memory management

    - by Dan Ray
    - (void)launchSearch { EventsSearchViewController *searchController = [[EventsSearchViewController alloc] initWithNibName:@"EventsSearchView" bundle:nil]; [self.navigationController pushViewController:searchController animated:YES]; //[searchController release]; } Notice the [searchController release] is commented out. I've understood that pushing searchController onto the navigation controller retains it, and I should release it from my code. I did just alloc/init it, after all, and if I don't free it, it'll leak. With that line commented out, navigation works great. With it NOT commented out, I can navigate INTO this view okay, but coming back UP a level crashes with a *** -[CFArray release]: message sent to deallocated instance 0x443a9e0 error. What's happening here? Is the NavigationController releasing it for me somehow when it goes out of view? The boilerplate that comes on a UINavigationController template in XCode has the newly-pushed controller getting released. But when I do it, it fails.

  • Identifying NHibernate proxy classes

    - by Marc Gravell
    I'm not an NHibernate user; I write a serialization utility library. A user has logged a feature-request that I should handle NHibernate proxy classes, treating them the same as the actual type. At the moment my code is treating them as unexpected inheritance, and throwing an exception. The code won't know in advance about NHibernate (including no reference, but I'm not aftaid of reflection ;-p) Is there a robust / guaranteed way of detecting such proxy types? Apparently DataContractSerializer handles this fine, so I'm hoping it is something pretty simple. Perhaps some interface or [attribute] decoration. Also, during deserialization; at the moment I would be creating the original type (not the NHibernate type). Is this fine for persistence purposes? Or is the proxy type required? If the latter; what is required to create an instance of the proxy type?

  • The Reason of Service Termination

When I go the the system events, I can find a piece of information like this one: Event ID: 7034, The [...] service terminated unexpectedly. It has done this [...] time(s). I know you can't give me an answer why this happens, but could you please give me a clue what to pay attention to to find the reason of that behaviour? For instance what kind of exceptions could make the OS close an application. Thank you in advance.

  • WCF Runtime Error while using Constructor

    - by Pranesh Nair
    Hi all, I am new to WCF i am using constructor in my WCF service.svc.cs file....It throws this error when i use the constructor The service type provided could not be loaded as a service because it does not have a default (parameter-less) constructor. To fix the problem, add a default constructor to the type, or pass an instance of the type to the host. When i remove the constructor its working fine....But its compulsory that i have to use constructor... This is my code namespace UserAuthentication { [ServiceBehavior(InstanceContextMode=System.ServiceModel.InstanceContextMode.Single)] public class UserAuthentication : UserRepository,IUserAuthentication { private ISqlMapper _mapper; private IRoleRepository _roleRepository; public UserAuthentication(ISqlMapper mapper): base(mapper) { _mapper = mapper; _roleRepository = new RoleRepository(_mapper); } public string EduvisionLogin(EduvisionUser aUser, int SchoolID) { UserRepository sampleCode= new UserRepository(_mapper); sampleCode.Login(aUser); return "Login Success"; } } } can anyone provide ideas or suggestions or sample code hw to resolve this issue...
