• How to reference an object in a lower fragment in android

  - by Silas Greenback

  I am trying to build a help screen that is going to go on a mediaplayer. The idea is to put a fragment with a transparent theme on top of the current view. (See How do I create a help overlay like you see in a few Android apps and ICS? for the basic idea). Now, I understand the steps in the mentioned link, but how do I connect the circles and arrows and paragraphs next to each one (explaining what each one was) to the lower object? Example, I have an object: R.id.music_button and I want there to be and arrow that points to music button. Trying to support as many devices as we do it will be very difficult to just draw a few pictures as part of the top layout and expect them to line up. Again, how do I reference an object on a fragment below the top level? Thanks

• Reading web-service information from assembly app.config file

  - by Benjamin Ortuzar

  I have a plugin architecture solution written in .NET C# 3.5, where each plug-in is an assembly loaded by the main project. Each plug-in connects to a different web-service, so I would like to have the configuration of that plugin in its own plugin.dll.config file instead of having it in the app.config of the main project. I have been looking around and I saw that i could load from each class its own config file: // Get the application configuration file. System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap,userLevel) I see how that would help me get the basic settings from the appSettings section, but I cant see a way to read the web-service information stored in the plugin.dll.config file. Any help on how to approach this situation is very welcome.

• Conditional type definitions

  - by pythonic metaphor

  I'm sure that boost has some functions for doing this, but I don't know the relevant libraries well enough. I have a template class, which is pretty basic, except for one twist where I need to define a conditional type. Here is the psuedo code for what I want struct PlaceHolder {}; template <typename T> class C{ typedef (T == PlaceHolder ? void : T) usefulType; }; How do I write that type conditional?

• How to integrate access control with my ORM in a .net windows form application?

  - by Ying

  I am developing a general database query tools, a .Net 3.5 Windows Form application. In order to make the presentation layer is independent of the database layer. I use an ORM framework, XPO from DevExpress. But, I have no access control function built in. I surfed Internet and I found in WCF Data Services, there is an interesting concept, Interceptor, which is following AOP(Aspect Oriented Programming). I am wondering who has such an experience to build access control in ORM. My basic requirement is : It should be a general method and controlled by users in runtime. So any hard coding is not acceptable. It could be based on attribute, database table, or even an external assembly. I am willing to buy a ready solution. According to the idea of AOP, an access control function can be integrated with existing functions easily and nearly not knowingly to the previous developer;) Any suggestions are welcome.

• CheckBox gets converted to Button in Flex

  - by Ravz

  Hi, I am new to Flex, so please bear with me. I have encountered a strange problem. There's a ActionScript class which dynamically creates basic UI element. So I create RadioButton as var rBtn:RadioButton = new RadioButton(); and then put it in a Panel Container. The problem is that it appears to be a Button. However it behaves like RadioButton. I have found this problem with one more guy who has posted it here. CheckBoxes and RadioButton looks like Push Buttons. Please help me out with this. Thanks.

• Optimizing MySQL statement with lot of count(row) an sum(row+row2)...

  - by Zombies

  I need to use InnoDB storage engine on a table with about 1mil or so records in it at any given time. It has records being inserted to it at a very fast rate, which are then dropped within a few days, maybe a week. The ping table has about a million rows, whereas the website table only about 10,000. My statement is this: select url from website ws, ping pi where ws.idproxy = pi.idproxy and pi.entrytime > curdate() - 3 and contentping+tcpping is not null group by url having sum(contentping+tcpping)/(count(*)-count(errortype)) < 500 and count(*) > 3 and count(errortype)/count(*) < .15 order by sum(contentping+tcpping)/(count(*)-count(errortype)) asc; I added an index on entrytime, yet no dice. Can anyone throw me a bone as to what I should consider to look into for basic optimization of this query. The result set is only like 200 rows, so I'm not getting killed there.

• Call REST service while impersonating a user that is already authorized to the glasfish server

  - by user1894489

  There are two web-applications deployed on a glassfish server. Both web applications provide a REST web service. the access to both web-services is secured via glassfish security constraints (at the moment BASIC Auth and file-realm). Let's say a user is accessing the service of web application A. After he is authorized, service A wants to call service B via REST client. Is there a way for a service to impersonate a user that is already authorized to the glasfish server? Maybe something like forwarding the security context or editing the headers? Is there another Filter? @Context private SecurityContext securityContext; username = securityContext.getUserPrincipal().getName(); password = ??? client.addFilter(new com.sun.jersey.api.client.filter.HTTPBasicAuthFilter(username, password)); Thanks!

• htpasswd, secure specific files in zend framework

  - by AKFourSeven

  Hi I have been bashing my head against the wall with this riddle and cannot find the way to solve this. I would like to secure couple of files to restrict access to certain pages but my attempts so far are unsuccessful. I do not want to use Zend Auth as it is a very small web site doing simple stuff. Here is a sample of what I have done: AuthUserFile /path/to/my/.htpasswd AuthName "Admin Restriction" AuthType Basic <Files file.phtml> require valid-user </Files> Is there any way to achieve this ?

• IIS and Windows 7

  - by xscape

  Hi, Im trying to host my wcf service to IIS. However when I click Basic Settings and Click Test Settings, it has an error. The server is configured to use pass-through authentication with a built-in account to access the specified physical path. However, IIS Manager cannot verify whether the built-in account has access. Make sure that the application pool identity has Read access to the physical path. If this server is joined to a domain, and the application pool identity is NetworkService or LocalSystem, verify that \$ has Read access to the physical path. Then test these settings again. The version of my IIS is 7.5.7600.16385 and my OS is Windows 7

• What type of websites does memcached speed up

  - by Saif Bechan

  I have read this article about 400% boost of your website. This is done by a combination of nginx and memcached. The how-to part of this website is quite good, but i mis the part where it says to what types of websites this applies. I know nginx is a http engine, I need no explanation for that. I thought memcached had something to do with caching database result. However i don't understand what this has to do with the http request, can someone please explain that to me. Another question I have is for what types of websites is this used. I have a website where the important part of the website consist of data that changes often. Often being minutes. Will this method still apply to me, or should I just stick with the basic boring setup of apache and nothing else.

• How and when to log account access login with PHP?

  - by Nazgulled

  I want to implement a basic login system in some PHP app where no cookies will be involved. I mean, the user closes the browser and the login expires, it will remain active during the browser session (or if the user explicitly logs out) otherwise. I want to log all this activity and I'm thinking that every time the user refreshes the page, opens a different link or logs out, I record that time as the last access made by that user, overwriting the previous access log. But my problem is when and how should I insert another record into the database instead of overwriting the last one? Should I just define a timeout and if the last access was made above that timeout, another log should be inserted into the database? Should the session expire too after that timeout? Or is there a better way? Ideally, I would like to log the "log out action" when the browser was closed, but I don't think there's a way to detect that is there? Suggestions?

• How to configure a has_many association with non-ActiveRecord model

  - by Callmeed

  My Rails app has a normal ActiveRecord "Account" model stored in the database. The model will store the URL to a remote XML file which defines some other objects. For example, the Account has_many :galleries but the Gallery model is simply defined by nodes in the XML document. So how do I get /accounts/1/galleries to show the galleries from that account's XML? How do I setup this relationship? I know how to do basic non-AR models, but I'm not sure how to define the association or if I need to create a Gallery model at all.

• dojo.gfx matrix transformation

  - by Linus

  Matrix transformations has got my head spinning. I've got a dojox.gfx.group which I want to be draggable with Mover and then be able to rotate it around a certain point on the surface. My basic code looks like this: this.m = dojox.gfx.matrix, . . . updateMatrix: function(){ var mtx = this.group._getRealMatrix(); var trans_m = this.m.translate(mtx.dx, mtx.dy); this.group.setTransform([this.m.rotateAt(this.rotation, 0, 0), trans_m]); } The rotation point is at (0,0) just to keep things simple. I don't seem to understand how the group is being rotated. Any reference to simplistic tutorial on matrix transformations would also help. The ones I've checked out haven't help too much.

  Hello, sorry if this questions is overly basic or has been asked before but I simply cannot figure it out.

It would be much appreciated. Thank you.

• Mvc Cocoa: How to get controller object for UIBarButtonItem target in view?

  I got a basic application where I want the action method of UIBarButtonItem to be in the parent controller. My view has been created programmatically, so I can't use IBAction. RootViewController - NavigationViewController - NavigationView - UIBarButtonItem Here's how have done it for the moment, it works for now... but it's not a really scalable technic (in NavigationView.m): BookAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; UIBarButtonItem *soundEffects = [[UIBarButtonItem alloc] initWithTitle:@"Sound Effects" style:UIBarButtonItemStyleBordered target:[delegate.rootViewController navigationViewController] action:@selector(soundEffectsClicked:)]; What would be a better technic to get the NavigationViewController object?

• ASP.NET Forms automation/serialization/binding

  - by creo

  I need to implement many forms in ASP.NET application (for IRS mostly). There are will be a lot of standard controls for each form (textboxes, dropdowns, checkboxes, radio). And business entity assigned to each. What's the best solution to automate this process? I need to: Have layout stored in DB (in XML). Layout must support several columns, tabbed interface Automatically bind business object values to the form Automatically read form values and write to business object Must support automatic validation Some basic workflows support would be good I used to work with TFS and saw how they implemented WorkItem templates (.wit files). In general this is all I need. But what framework did they build it on? How can I utilize this solution? I know about Dynamic Data only: http://www.asp.net/dynamicdata

• Pass HTML form entries into a Javascript array to then be written to a client side cookie?

  - by Tom

  I'm building a bit of a test-case JS application, something very basic, but have run into some problems. I'm trying to use a HTML form for a user to enter a number, which is then written to a Javascript Array. The user then has the option to write that same array to a local (client side) cookie. (I understand the security implications of this - it's a test-case and not for commercial use.) However, I can't make the connection - how can I capture the HTML entry, press 'submit' which will send it to a JS array, where the user can then press a different 'submit' which will write the array to a text file? If anyone can help I'd appreciate it because it's been nearly 6 hours and it's not funny anymore.

• mocking command object in grails controller results in hasErrors() return false no matter what! Plea

  - by egervari

  I have a controller that uses a command object in a controller action. When mocking this command object in a grails' controller unit test, the hasErrors() method always returns false, even when I am purposefully violating its constraints. def save = { RegistrationForm form -> if(form.hasErrors()) { // code block never gets executed } else { // code block always gets executed } } In the test itself, I do this: mockCommandObject(RegistrationForm) def form = new RegistrationForm(emailAddress: "ken.bad@gmail", password: "secret", confirmPassword: "wrong") controller.save(form) I am purposefully giving it a bad email address, and I am making sure the password and the confirmPassword properties are different. In this case, hasErrors() should return true... but it doesn't. I don't know how my testing can be any where reliable if such a basic thing does not work :/ Here is the RegistrationForm class, so you can see the constraints I am using: class RegistrationForm { def springSecurityService String emailAddress String password String confirmPassword String getEncryptedPassword() { springSecurityService.encodePassword(password) } static constraints = { emailAddress(blank: false, email: true) password(blank: false, minSize:4, maxSize: 10) confirmPassword(blank: false, validator: { confirmPassword, form -> confirmPassword == form.password }) } }

• Creating Visual Studio Templates

  - by vanja.

  I'm looking to create a Visual Studio 2008 template that will create a basic project and based on remove certain files/folders based on options the user enters. Right now, I have followed some tutorials online which have let me create the form to query the user and pass the data into an IWizard class, but I don't know what to do from there. The tutorials provide a sample to do some simple substitution: code: Form1 form = new Form1(); DialogResult dlg = form.ShowDialog(); if (dlg == DialogResult.OK) { foreach (KeyValuePair<string, string> pair in form.Parameters) { if (!replacementsDictionary.ContainsKey(pair.Key)) replacementsDictionary.Add(pair.Key, pair.Value); else replacementsDictionary[pair.Key] = pair.Value; } } form.Close(); but I'm looking to selectively include files based on the user settings, and if possible, selectively include code sections in a file based on settings. Is there a clever way to do this, or will I manually have to delete project files in the IWizard:ProjectFinishedGenerating()?

• Posting Documentation onto a Joomla Site

  - by Chris Spicer

  I would like to create some documentation and post it onto my Joomla website. This documentation would be something along the lines of the MSDN documentation: i.e. each page would follow a basic template. Intuitively I feel I have two ways of achieving this: 1) Creating each page of documentation as a separate article, and then linking them up. 2) Creating some kind of template and filling the information from a database. The second option being preferable in the long run. Unforunately I have no idea how to achieve what I'm looking for. I hoped that there would be a component out there that woud help me, but Googling for 'Joomla Documentation' just brings up the documentation for Joomla itself. Has anyone out there put documentation on their site, and how did they achieve it?

• How to configure Hibernate database reverse engineering tool to map database table relation as a ent

  - by Piotr Kochanski

  Is it possible to configure Hibernate reverse engineering and code generation tool in such a way that one-to-many relation between tables is mapped to entities inheritance instead of enrites relation? I have Person table and Employee table, which are related with the foreign key (Person contains basic information, Employee the rest). In my Java code I would like this relation mapped to inheritance Employee extends Person. This can be done by hand, but maybe I missed some custom configuration parameter that I can use. I couldn't find any official documentation - docs link on RedHat Hibernate page (http://www.hibernate.org/5.html#A10) is broken...

• New to javascript, why is jQuery such a beast?

  - by gnucom

  Hey Everyone, I'm new to javascript (functional programming is okay for me, though) and I am wondering how jQuery got away with some of the design decisions they made. Is it just too much work to fix now or what? For instance, there seems use of strange symbols in strings when accessing elements in the DOM or weird function definitions for $, that are forcing me to check references every other time I want to get some basic data. Can someone point me to a learning source where I can learn all of these nuances of jQuery (jQuery's examples just don't cut it, they're too spread out)? Maybe someone has a super good reference site/pdf for jQuery? Thanks

• Set Caret position with JTextArea in JScrollPane

  - by Albinoswordfish

  Right now I have a JTextArea inside of a JScrollPane. For the current content it has both a vertical and horizontal scroll bar showing up. I'm trying to implement a search functionality where a user can search for a certain string and it will set the caret position to the first occurrence of that string. However it seems that JScrollPane only scrolls vertically when I set my caret position. So matching strings going off the JTextArea horizontally will completely get missed and the horizontal scroll bar won't scroll at all. I'm using the basic function setCaretPosition() for the JTextArea Does anybody have any idea why my JScrollPane isn't moving horizontally using setCaretPosition() Edit: It appears the horizontal scroll bar is scrolling but it moves so little that it's barely noticeable. I can only see the very first pixel of the character. Is there a way to have the scrollbar center (or as much as possible) to the caret position?

• Running The JVM From Within An MXML Component

  - by Joshua

  Thinking outside of the box here... What possible basic approaches could be taken in an effort to create a Flex component that could run Java? I know I can easily use flex to browse to or launch a Java app, but there are things I can only do if I can run the Java from WITHIN an MXML Component. I the strictest sense, I know it's not impossible (ie: if you had all the source code for flex and for the jvm), but what's the least impractical means to this end? Showcase your creativity.
