  • Switching function states

    - by webzide
    Dear experts, I would like to implement a API of Javascript that sort of resemble a light switch. For instance, there are two buttons on the actual HTML page act as the UI. Both of the buttons have event handlers that invokes a different function. Each function have codes that act like a state, for instance. button1.onclick=function (){ $("div").click( //code effects 2 ) } button2.onclick=function (){ $("div").click( //Code effects 2 ) } I the code works fine on the surface but the 2 state functions overlap. the effects is going to take place for the rest of the way until the next reload of the document. Basically what I want to achieve is that when 1 button is clicked, it will switch "OFF" the state of function invoked by the other button and vice versa. Thus, the effects achieved are unique are not overlapped. Is there anyway to achieve this or could any experts point me to the right direction. Thanks in advance.

  • JavaScript QR Code Reader - can it be done? Or, Remote Service?

    - by Myk
    I'm doing a bit of preliminary research on an upcoming project and I have a quick question that I figure I'll throw up here while I look elsewhere, in case anyone has any experience with this. The question is simple: is it possible to read a QR code using JavaScript? Is there a remote service to which I can pass a bitmap object from a camera and do it that way? Are there currently any libraries that allow this? The project is going to be deployed to various mobile devices and we'd like to try to use Appcelerator to make it work. I know Appcelerator does expose the Camera API on its host devices, but whatever we do with it has to be able to parse QR codes. Is this something that can be done? Thanks in advance! myk

  • (VB or C#) Run app in system tray and listen to keyboard input even when the app is not in focus

    - by Avinash Sonee
    I want to make an app which on loading sits in the system tray and even after I open another program (say notepad or vlc or anything) i.e. even when the app is not in focus and if I press "G" on my keyboard, the tray icon should show a tool tip - "key G is pressed". I have tried several codes but nothing works when the app goes out of focus. I can use Register Hot Key (http://msdn.microsoft.com/en-us/library/ms646309(VS.85).aspx) but it needs a modifier also (like Ctrl or Alt etc. along with my key G). So, is there any way I can achieve this? something which many tray icons do like antivirus apps, etc. and I do not want to use AutoHotkey application. I want to build one but need some help. Thanks!

  • Zend Framework AjaxContext filters the results and Decorators not removable

    - by Janis Peisenieks
    Ok, since this problem has 2 parts, it will be easier to explain them together. So here goes: I am trying to remove the default decorators from these elements, since I am using a little different way of styling them. But no matter what i do, the DtDDWrapper still shows up. If I try to remove all of the decorators, all of the fields below disappear. public function newfieldAction() { $ajaxContext = $this->_helper->getHelper('AjaxContext'); $ajaxContext->addActionContext('newfield', 'html')->initContext(); $id = $this->_getParam('id', null); $id1=$id+1; $id2=$id+2; $element = new Zend_Form_Element_Text("newTitle$id1"); $element->setOptions(array('escape'=>false)); $element->setRequired(true)->setLabel('Vertiba')->removeDecorator('label'); $tinyelement=new Zend_Form_Element_Text("newName$id"); $tinyelement->setRequired(true)->setOptions(array('escape'=>false))->setLabel('Vertiba')->removeDecorator('label'); $textarea_element = new Zend_Form_Element_Textarea("newText$id2"); $textarea_element->setRequired(true)->setOptions(array('escape'=>false))->setLabel('Vertiba')->removeDecorator('label'); $this->view->descriptionField = "<td>".$textarea_element->__toString()."</td>"; $this->view->titleField = $element->__toString(); $this->view->field = $tinyelement->__toString(); $this->view->id=$id; } The context view script seams to trim my code in one way or another. When I try to put a <td> or a <table> tag in the view script, it just skips the tags. Is there a way to stop this escaping from happening? My view script: id; ?" asdfasdfasdfasd field ? titleField ? descriptionField ? id ?"remove P.S. the code formatting system is barfing at me, could someone please help me with the formatting of the code?

    I want to document the default value of an enum typed field: /// <summary> /// The default value is <see cref="Orientation.Horizontal" />. /// </summary> public Orientation BoxOrientation; The compiler warns that it couldn't resolve the reference. Prefixing F: or M: silences the compiler, but E: also does, so I'm unsure what prefix is correct.
