  • Joomla Session Variable as Plugin Parameter

    - by dosboy
    I have a Joomla plugin which takes varying parameters. I need to retrieve one of these parameters from the current session. I've tried using Jumi and a little PHP snipped to retrieve the value and output it in the plugin's parameter list, but the Joomla plugin parser only handles the outter-most set of curly braces. ex. {fabrik view=table id=62 resetfilters=1 fab_tours_ro___tour_id=[tour_id]} [tour_id] I need to retrieve from the current session. I've tried {fabrik view=table id=62 resetfilters=1 fab_tours_ro___tour_id={jumi [scripts/get_tour_id.php]}} In that case the {jumi} tag never gets parsed. I could hack the {fabrik} plugin, but I'd prefer to do this without making any core or component changes, especially since I update Fabrik quite regularly via svn.

  • Why can i not rewrite parent class?

    - by latvian
    I want to rewrite core/adminthtml/block/widget/tabs.php class which is a super class for core/adminhtml/block/sales/order/view/tabs.php class. Here is config code for both scenarios: <blocks> <adminhtml> <rewrite> <sales_order_view_tabs>Jimmy_SalesAffil_Block_Widget_Tabs</sales_order_view_tabs> <widget_tabs>Jimmy_SalesAffil_Block_Widget_Tabs</widget_tabs> ..... </rewrite> </adminhtml> </blocks> While I am able to rewrite ...view/tabs.php, I am not able to rewrite the super class. Why? Is it possible? How?

  • No Parameterless Constructor defined for - ViewModel with UOW

    - by TheVillageIdiot
    I have a view model class which uses UnitOfWork to some database operations like fetching of items to create select lists and IPrincipal for some auditing (like modified by etc.). It cannot work without this UOW. I have configured my web site to use Ninject to inject UOW into Controllers. From controller I pass this UOW when creating view model. But when performing POST operation I am getting No parameterless constructor defined for this object. I have few SelectList type of properties which I have excluded with Bind attribute. How can I overcome this problem? Can I configure Ninject to create the objects of this type and make ModelBinder use it?

  • Specifying force and angle in ApplyImpulse in box2d

    - by Deepak Mahalingam
    I need to apply an impulse on a object with a particular force and at a particular angle in Box2d. If I am right the syntax would be the following: body.GetBody().ApplyImpulse(new b2Vec2(direction, power),body.GetBody().GetWorldCenter()); The problem is my direction is in angles. I found a discussion where it was said that the way we can convert an angle into a vector would be as: new b2Vec2(Math.cos(angle*Math.PI/180),Math.sin(angle*Math.PI/180)); Now I am not sure how to combine these two. In other words, if I wish to apply a force of 30 units at an angle of 30 degrees at the center of the object, how should I do it?

  • Problems after installing Ubuntu LiveUSB on my 2nd HD

    - by user113106
    I decided to create a Ubuntu USB installer using the Universal USB Installer, selecting a Ubuntu 12.10 ISO. I selected my D: drive, my NON-windows7 carrying drive as install. After this I Re-booted my system and my PC began to Run the Ubuntu Boot-startscreen every time I power up the machine, giving errors like this: Root=Unknown I used my girlfriend's laptop to create, on the exact same way, a real! USB Ubuntu installer. Booting from that USB, picking the option Run Ubuntu from this USB I get the following error: http://postimage.org/image/63qkv98c1/ Let's try installing it from that USB to a Hard-Disk: http://postimage.org/image/usqbwymfx/ As I said: I do not have the Option to pick my Boot-section, at this very moment I can only access to the Ubuntu installation and nothing else. I've read about 90% of other Questions that could've been related, but I could not find a solution. BTW I'm running a Acer Aspire 2Quadcore 4gb DDR 2 Ati Radeon HD, 64bit and I've set my Bios OS-usage from Windows to "Others"

  • Pattern to iterate Request Params

    - by NOOBie
    My view is not a strongly typed view and I need to iterate through Request Params in the controller action to determine the values posted. Is there a better way to iterate through the nameValueCollection AllKeys? I am currently looping through the Request Params and setting values appropriately. foreach (var key in Request.Params.AllKeys) { if (key.Equals("CustomerId")) queryObject.CustomerId = Request.Params[key]; else if (key.Equals("OrderId")) queryObject.OrderId= Request.Params[key]; //and so on } I see a considerable amount of repetition in this code. Is there a better way to handle this?

  • Windows Not Sleeping All Night

    - by John Paul Cook
    Having a computer wake up when you don’t want it to wastes electricity and drains the battery on mobile devices. My desktop had been waking up at night, so I assumed it was some network traffic on my home network. I unchecked Allow this device to wake the computer on my network adapters . Figure 1. Network adapter Power Management tab. That didn’t solve the problem. I included the screen capture in Figure 1 because it could be part of the solution for someone else. To identify the root cause instead...(read more)

  • My laptop doesn't always boot to login

    - by GUI Junkie
    I have an recurring problem. Every once in a while, no pattern, the laptop freezes during boot. Sometimes at a black screen, sometimes a black screen with a not blinking cursor... The solution is to power down the laptop, cross my fingers and boot again. Sometimes it takes four or five reboots, but in the end I always get the system up and running. What bugs me is the fact that the boot is not 'stable' in a sense that apparently it doesn't always do exactly the same thing. I'm still using 10.10. The question is whether there is anything that can be done to make the system stable. (Does 11.04 have the same issue?) Edit: Today the same thing happened. First a black screen with a non blinking cursor. Second a black screen. Third login screen.

  • Full stack framework for Java

    - by Jonathan Barbero
    Hello everyone, I'm looking for a full stack framework (from persistency to view generation (CRUD)) for Java. I don't have experience with Rails style frameworks, like Grails, but I worked a lot with Hibernate, Struts, Spring ... I prefer a framework that let you naturally modify the business domain design with the less effort ( i.e. writing the sql querys to modify the tables and constrains, change the view pages, etc ... ). I was looking a bit about this topic, I saw Naked Objects for example but its development has stopped. So, I want to hear about your experience. Thanks in advance.

  • How to call a jquery function from an action method in controller?

    - by Hasan Fahim
    I have a requirement to open a popup from an action method in controller. The action method is basically registering a user. [HttpPost] public ActionResult Register(RegisterModel model) { if (ModelState.IsValid) { MembershipCreateStatus createStatus; Membership.CreateUser(model.UserName, model.Password, model.Email, null, null, true, null, out createStatus); if (createStatus == MembershipCreateStatus.Success) { FormsAuthentication.SetAuthCookie(model.UserName, false /* createPersistentCookie */); //------------------------------------------ //I need to call a jquery function from here //------------------------------------------ return RedirectToAction("Index", "Home"); } else { ModelState.AddModelError("", ErrorCodeToString(createStatus)); } } return View(model); } The jquery function, present in the view, would just make a hidden DIV, visible, and set the opacity, etc, to represent a popup. I need to call such a jquery function from the controller's action method shown above.

  • How to split page and reveal stuff underneath?

    - by sudo rm -rf
    Hi there. I've already achieved this on my iPhone app, but I want to know if it's possible on an HTML page, maybe using CSS effects or similar. As you can see, the current view is split, the bottom part is moved down, and another view is revealed underneath. I have a page I'd like to try this on. Any ideas if this is possible, and any specifics as to how I can do it? I'm quite new to HTML coding, so please take it easy on me. :) Thanks in advance!

  • Closing several android activities simultaneously

    - by teedyay
    In my application you can navigate through several Activities until the Activity stack is quite deep. We'd like a button on every Activity that will take you straight back to the main menu - i.e. pop all Activities from the stack except the first one. I've put the button in a View that I can easily put on every Activity in the application, but I can't figure out how to close several Activities in one fell swoop. (If possible, it would be good if the View could work out how many Activities to close by itself - i.e. detect how deep on the stack its own Activity is.)

  • MVC best practice when adding functions to controller?

    - by Patrick
    Hi I'm writing a function in my controller; this is supposed to take in a form, process it, register the user in DB, send a confirmation email etc etc. to avoid this function to be too cluttered, I was thinking of calling some sub-functions (eg: function registration() { //process form.. _insertInDb($formdata) _send_mail($address); //load confirmation view.. } function _send_mail($to) { //code here } function _insertInDb($formdata) { //other code here... } I'm not sure whether writing all the functions in the controller would be best practice -maybe I should insert all 'supporting' function (eg send_mail and insertInDb in this example) in another file and then import them? This would probably make the controller much more readable.. what's your view?

  • Booting but not rebooting from external USB hard drive, what could be the problem?

    - by user8276
    I have a Dell Inspiron 6400 laptop with a dead internal hard drive controller. It boots perfectly from CD or USB. I therefore removed the internal hard drive and installed Ubuntu 10.10 Maverick onto an external USB hard drive. It boots and runs perfectly when doing a "cold start" of the PC. However, when I choose restart/reboot in the Ubuntu menu (e.g. after an update), I get this error message from the BIOS: "No bootable devices, strike f1 to retry boot, f2 for setup utility, press f5 to run onboard diagnostics". I can make the system boot again by pressing f2 or f5 and exiting the utility without having done anything. Or, I can simply power off the system and do a new "cold start". Does anyone know the likely reason for this problem and how to fix it. It is not a big issue but an annoyance that I would like to fix if possible.

  • How long till HTML5 canvas becomes a viable game development platform?

    - by Shouvik
    So I have been working on web application. So invariably what it boils down to is making simple games which were previously based on flash or openGL. Now I know apple was moving away from flash because its proprietary unlike their stance that its got "pathetic performance"! Not true, try playing a canvas game, I can assure you at any point of time (including when its idle) it will use up a fair bit of processing power just to redraw the UI. Now I do understand that this is my fault because when the game is not active I should not be redrawing the canvas, but honestly its a lot of work and I suppose there should be libraries which should be able to assist me with that! So, how much will it be before I see a decent canvas library which handles these "tiny" issues for me? I can't honestly expect Steve Jobs to be doing anything more for HTML5! I someone knows of a good library, I am all ears...! :) PS: I use mootools and am presently using Mootools Canvas Library.

  • Selecting the usercontrol to the relating datatemplate in mvvm

    - by msfanboy
    Hello, I have lets say a WeeklyViewUserControl.xaml and a DailyViewUserControl.xaml. Normally I used stuff like this to switch content: <DataTemplate DataType="{x:Type ViewModel:LessonPlannerViewModel}"> <View:LessonPlannerDailyUC/> </DataTemplate> This worked so far. But now I have still the WeeklyViewUC which uses 90 % of the LessonPlannerViewModel code so I want to make this additionally: <DataTemplate DataType="{x:Type ViewModel:LessonPlannerViewModel}"> <View:LessonPlannerWeeklyUC/> </DataTemplate> but this can not work, because from where does the ContentControl know that VM (LessonPlannerViewModel) should display a DailyViewUC or a WeeklyViewUC ? <ContentControl Content="{Binding VM}" />

  • Image gets slightly erased on SWT/Windows

    - by zvikico
    I have an Eclipse plugin which includes a view. The view has several icons in the toolbar. I'm experiencing a very strange problem: on Windows, in some occasions (after prolonged use), one of the icons gets slightly erased. This does not happen on other platforms. This looks like a memory leak or some other resource misuse, but I just can't figure out where. The rest of the icons, which are initialized and used in the exact same manner are not affected. I tried working with Sleak, but I really don't see anything out of the ordinary. Any help would be appreciated.

  • fast scrolling background

    - by Andre
    i want a game that scrolls the background in a similar way to a UItableView. I solved it with a timer that moves the background up and brings another copy of the same picture up if (bg1.center.y <= - self.view.bounds.size.height/2 ) { bg1.center = CGPointMake(bg1.center.x, 690); } if (bg2.center.y <= - self.view.bounds.size.height/2 ) { bg2.center = CGPointMake(bg2.center.x, 690); bg1.center = CGPointMake(bg1.center.x, bg1.center.y - movement); bg2.center = CGPointMake(bg2.center.x, bg2.center.y - movement); But the faster i move the pictures the more problems occur: There are appearing gaps between the backgrounds and they are getting biggiger the faster i move them! movement is defined by the speed of swiping over the screen Any idea to solve that?

  • Two problems, both with either lock or suspend.

    - by user199208
    I recently did two things that may be the cause of either of them. 1) I started using a second screen 2) I installed xscreensaver instead of the stock, power saving option. My first question is about suspend: every time I wake from suspend, networking is disabled. While I've seen multiple posts about that on here, it didn't start happening until recently. Second, lock seems to be disabled now. Are both of these problems a bug, or was this caused by the second screen or maybe xscreensaver?
