• Zend Framework - tinyMCE - plugin folders are mistaken to be controllers? Help

  - by Ali

  Hi guys I'm trying to integrate the tinymce plugin however I'm running into problems such that almost every feature which requires a plugin to be rendered i.e the add url popup or add image pop up - it opens an empty pop up window. Even if I try to open it inline I get the same blank popup window.. I noticed that whenever I click on lets say url button in tinymCE it opens with reference to my localhost and because of that I'm assuming my application is mistaking the containing javascript folder to be some controller or action. How can I fix this please - I've set up mod rewrite to allow clean urls as well as ignore the javascript folder but this is a different issue altogether :( what should I be looking at here.. I can't notice any error sin firebug..

• Spring security accessing principal

  - by wuntee

  When using spring security, specifically with @notation; what is the proper way to access the principal in a Controller? Lets say the following is my controller, but I would like to access the principal in the secure() method somewhere... @Controller public class LoginController { @RequestMapping(value = "/login", method = RequestMethod.GET) public String login(ModelMap map, @RequestParam(value="fail" , required=false) String fail){ map.addAttribute("title", "Login: AD Credentials"); if(fail != null){ map.addAttribute("error", "Invalid credentials"); } return("login"); } @RequestMapping("/secure") @PreAuthorize("isAuthenticated()") public String secure(ModelMap map, String principal){ System.out.println(principal); return("secure"); } }

• How should I go about creating a point system for users like SO and yahoo answers?(PHP)

  - by ggfan

  I am creating a voting system for a Q&A site project in which if a user asks a question, he/she losses -5 points; answer a question +5, vote a question +1, etc. (kind of like SO and yahoo answers) --To create the basic arithmetic, I have a "users_points" table that relates the user_id and their total points. +---+---------+ | 1 | 100 | +---+---------+ | 2 | 54 | +---+---------+ --Basically if the users does certain task, it would + or - the points. How do I prevent users from say voting an answer up 100 times. ex: I want a user to be only able to vote once per question, etc.

• Most optimized way to calculate modulus in C

  - by hasanatkazmi

  I have minimize cost of calculating modulus in C. say I have a number x and n is the number which will divide x when n == 65536 (which happens to be 2^16): mod = x % n (11 assembly instructions as produced by GCC) or mod = x & 0xffff which is equal to mod = x & 65535 (4 assembly instructions) so, GCC doesn't optimize it to this extent. In my case n is not x^(int) but is largest prime less than 2^16 which is 65521 as I showed for n == 2^16, bit-wise operations can optimize the computation. What bit-wise operations can I preform when n == 65521 to calculate modulus.

• How to use DAOs with hibernate/jpa?

  - by Ari

  Assuming the DAO structure and component interaction described below, how should DAOs be used with persistence layers like hibernate and toplink? What methods should/shouldn't they contain? Would it be bad practice to move the code from the DAO directly to the service? For example, let's say that for every model we have a DAO (that may or may not implement a base interface) that looks something like the following: public class BasicDao<T> { public List<T> list() { ... } public <T> retrieve() { ... } public void save() { ... } public void delete() { ... } } Component interaction pattern is -- service DAO model

• In SELENIUM, how to I change focus to a new popup tab?

  I'm using Selenium and Firefox. I have a link on a page (say linkA) that opens a new page in a new tab. The new tab is displayed when linkA is clicked. I then want to interact with the new page. Here is my selenium script: click linkA pause 5000 selectWindow Title click linkB (note: linkB is on the new page) Selenium cannot identify the new tab. It reports: [warn] Link has target '_blank', which is not supported in Selenium! Randomizing target to be: selenium_blank24003 Is there any way to tell Selenium to interact with the displayed tab?

• How do I specify the com+ server when registering a vb6 com+ application without using clireg?

  - by user85759

  I've found lots of documentation on how to install com+ components with WiX or an exported msi from dcomcnfg but the problem with these approaches is I can't see where to specify the com+ server. Currently we register the components with clireg and the -s switch which allows us to specify the com+ server like so: clireg32.exe BLEH.VBR -s COMSERVER -t BLEH.TLB -d This is messy to say the least and I've been trying to get this into some automated form of installation that doesn't involve calling a batch file full of clireg32 calls. Currently WiX is the backbone of our packaging automation so a solution with WiX would be awesome. Thanks.

• How to keep a process running on a remote windows server

  - by DutrowLLC

  I need to implement a background process that runs on a remote windows server 24/7. My development environment is C#/ASP.NET 3.5. The purpose of the process is to: Send reminder e-mails to employees and customers at appropriate times (say 5:00PM on the day before a job is scheduled) Query and save GPS coordinates of employees when they are supposed to be out on jobs so that I can later verify that their positions were where they were supposed to be. If the process fails (which it probably will, especially when updates are added), I need for it to be restarted immediately (or within just a few minutes) as I would have very serious problems if this process failed to send a notification, log a GPS coordinate, or any of the other tasks its meant to perform.

• OpenGLES mix and match blending options complicated question

  - by DevDevDev

  So I have a background line drawing, black and white. I want to be able to draw over this, keeping the black lines in there, and drawing only where it is white. I can do this by using glBlendFunc(GL_DST_COLOR, GL_ONE_MINUS_SRC_ALPHA); And the black stays black and white gets whatever color I want. However in the white areas, I want to be able to draw some color, pick to another color and then blend. However this doesn't work because the blend function is messed up. So what I was thinking is having a linedrawing framebuffer, and a user-drawing framebuffer. The user draws into the userdrawing framebuffer, with a different blending, and then I switch blending options and draw into the linedrawing framebuffer. But i don't know enough OpenGL to say whether or not this will work or is a stupid idea. Thanks a lot

• Mysql out of disk space

  - by Paddy

  I have just finished developing a rails app which has a mysql db as a backend. The app is meant for high traffic and will store lots of information. I am planning to set up my own web server and host the site from it. If in future my disk space runs out i would want to expand by adding more space. But say if my mysql database is housed in my /disk0s1 and by adding a new drive i have more partitions (and hence more disk space), how then would i extend my database to store information on those partitions too, and at the same time prevent any information from being written on the original partition. Should i go for multiple databases? if so how? If i went for a hosting solution i wouldn't be bothering about this as i would just have to worry about making payments for the extra space :) I always wondered how space is added on-the-go by these webhosts. Is there any specific mysql configuration that i have to make?

• custom button: properties change, button should be redrawn

  - by Rutger

  Hi I'm developing an Android app. I have class derived from button to represent a special type of button. This special type has some properties (integers) and according to these one or more circles have to be drawn on top of the button. So I overrode the onDraw function, which looks the values up and accordingly draws the circles. But the class has a function to set new values for its properties. So new values are set but the changes are not reflected in the UI. It seems like the onDraw function is not called. When later I click the button or show a pop up message above my interface the onDraw function is called and the button is drawn correctly. So my question: when changing the properties how can I say that the button has to be redrawn? Thanks a lot!

• How to make a spam tester

  - by aquero

  In my project I need to make a spam tester to check the spam score of the mails prepared to be sent. When I searched, I found Spam Assassin, which they say is used as sapm filters in many mail servers. Can I create a spam tester using Spam Assassin? Another option I found is one Litmus API, which is a paid service. Is there any options other than these two? Freeware is more preferred. My project is a J2EE web application using Spring.

• How do I stop displaying a J2ME MIDP application, just before destroying it?

  - by Paul Marshall

  I have a J2ME application where the user has the option to dial a phone number from within the application. This should be the last thing the user does with the app, so it should stop displaying anything. My current code: public void callAndExit() { // use a platform-specific request to dial MyMidletThingummy.getInstance().platformRequest( "tel:" + number ); notifyDestroyed(); } The call works just fine, uses the phone's native way of calling, etc. The problem is that, just after the call completes (whenever the user hangs up), my application displays for a split second before being destroyed. Is there something I can do so that I stop displaying the MIDlet (and, say, show the phone's home screen or whatever else it would rather display), then dial out?

• How can I only allow certain filetypes on upload in php?

  - by Chris

  I'm making a page where the user upload a file. I want an if statement to create an $error variable if the file type is anything other jpg, gif, and pdf. Here's my code: $file_type = $_FILES['foreign_character_upload']['type']; //returns the mimetype if(/*$file_type is anything other than jpg, gif, or pdf*/) { $error_message = 'Only jpg, gif, and pdf files are allowed.'; $error = 'yes'; } I'm having difficulty structuring the if statement. How would I say that?

• Decimal Value is Zero when it should be 0.0x

  - by Mike Wills

  If this was previously talked about, I'm sorry, I had a hard time searching on this. I am calculating a depreciation rate. One portion of our calculation is 1/life in months. My table stores this data in a decimal field. I tried test = 1 / estimatedLife; but the result of the calculation of test (which is defined as a decimal) is 0. Say the estimated life is 36 months. So 1/36 should equal 0.02777778. Any thoughts of what I am doing wrong? BTW, I changed the test to a double and had the same result.

• Re-send POST request easily - what tools?

  - by Fabien

  I am looking for an easy way to re-send POST request to the server within the browser mainly for debug purposes. Say you have a XHR request which contains POST parameters that is to be send to the server. After having changed the script on the server side, you would like to resent the very same request for analyzing the output. What tool could help? I guess it is a browser's extension. I already tried extension Tamper Data for Firefox which does the job as you can "Replay in browser". But for my taste, it is not enough straight forward, as there are 3 - 4 clicks to get the result of the request. Unfortunately, curl would not be suitable for my needs as my application has a session's cookie.

• How does Read-Only affect a Directory?

  - by ispiro

  I've found that I can write (say, copy a file into) a Read-Only directory. That is, a Directory with ...Attributes = FileAttributes.ReadOnly.I can even change its name. The only thing I've found that can't be done is to delete it. Is that really the only thing that ReadOnly prevents? EDIT: Here's the code: (The Directory is empty.) (new DirectoryInfo(path)).Attributes = FileAttributes.ReadOnly; Directory.Delete(path); It throws an Access to the path 'c:\... is denied. exception. But after changing ReadOnly to Normal it works fine. So what does a ReadOnly prevent, and what doesn't it prevent?

• BindingList projection wrapper

  - by Groo

  Is there a simple way to create a BindingList wrapper (with projection), which would update as the original list updates? For example, let's say I have a mutable list of numbers, and I want to represent them as hex strings in a ComboBox. Using this wrapper I could do something like this: BindingList<int> numbers = data.GetNumbers(); comboBox.DataSource = Project(numbers, i => string.Format("{0:x}", i)); I could wrap the list into a new BindingList, handle all source events, update the list and fire these events again, but I feel that there is a simpler way already.

• Grails/Groovy taglib handling parsing dynamically inserted tags.

  - by Dan Guy

  Is there a way to have a custom taglib operate on data loaded in a .gsp file such that it picks up any tags embedded in the data stored in the database. For instance, let's say I'm doing: <g:each in="${activities}"> <li>${it.payload}</li> </g:each> And inside the payload, which is coming from the database, is text like "Person a did event <company:event id="15124124">Event Description</company:event>" Can you have a taglib that handles company:event tags on the fly?

• DataModelSelection on list exposed via EntityQuery

  - by Kalpana

  Is it possible to have support for enabling DataModelSelection on a list page paginated via EntityQuery? (All the examples load the list by performing a query on the @Factory method). But, I would like to re-use the existing pagination mechanism and just enable the ability to support DataModelSelection on it. I am also assuming that DataModelSelection is capable of tracking a single row in a List, how do we extend this to support a certain action (say deletion, activation ...) of multiple rows. I am a newbie and would appreciate any help on this topic. I have already gone through the samples shipped as part of Seam (booking, message). I have already posted this in seam users forum, but I am yet to get a response

• How do I access variables with hyphenated names in Smarty?

  - by abeger

  I've got a PHP page that parses an XML file with SimpleXml, then passes that object to a Smarty template. My problem is that the XML file has hyphens in its tag names, e.g. video-player. In PHP, this is no problem, I just use $xml->{'video-player'} and everything's fine. Smarty, on the other hand, throws a fit when I try to use that syntax. The only solution I've come up with so far is to use a variable to store the name, e.g., { assign var=name value="video-player" } { $xml->$name } But this isn't terribly graceful to say the least. Is there another, better, approach to referring to a hyphenated variable name in Smarty?
