  • Is there any way to use imagegrabwindow() with Firefox or Chrome?

    - by patternsofchaos
    I'm trying to generate website thumbnails programatically in PHP. To do this, I'm using imagegrabwindow() with a COM object: $browser = new COM("InternetExplorer.Application"); $handle = $browser->HWND; $browser->Visible = true; $browser->Navigate($pre.$URL); while ($browser->Busy) { com_message_pump(4000); } $img = imagegrabwindow($handle); What I'm wondering is if there is any way to do the same thing with Firefox or Chrome? Can I invoke either of them with PHP COM?

  • Getting the dynamic value of a checkbox in repeating region loop with Jquery

    - by John
    How do I get the values of a check box that is in a repeating region with its values dynamically generated from a recordset from the database.I want to retrieve the value when it is checked and after I click on a link.The problem is that it is retrieving only the first value of the recordset which is 1.This is the code: //jQuery $(document).ready(function(){ $("#clickbtn").click(function(){ $("input[type=checkbox][checked]").each(function(){ var value=$("#checkid").attr('value'); $("#textfield").attr('value',value); }); return false; }); }); //html <td width="22"><form id="form1" name="form1" method="post" action=""> <input type="checkbox" name="checkid" id="checkid" value="<?php echo $row_people['NameID']; ?>" /> </form></td> I would appreciate the help.

  • Pass an event into a constructor

    - by Vaccano
    I have a class that I want to be able the handle the mouse up event for a grid. I tried to create it with a static method call like this: MyDataBinding.BindObjectsToDataGrid(ListOfObjectsToBind, myGrid.MouseUp); The end goal being that in the method I would assign a delegate to the MouseUp PassedInMouseUp += myMethodThatWillHandleTheMouseUp; Looks good here (to me) but the compiler chokes on the first line. It says that I can only use MouseUp with a += or a -=. Clearly I am going about this the wrong way. How can I get a different class to handle the mouse up with out having to: Pass in the whole grid Expose the method that will be handling the mouse up as a public method. Or, is this just a limitation and I will have to do one of the above?

  • Return value in Visual Studio's Autos window

    - by Dave
    When I used to develop in C++, I remember that Visual Studio had an entry in its Autos window whenever returning from a function call. This entry would tell me what value was returned from that function. One might argue that if a function returns a value, then you should set a variable to that value, i.e. int i = GetRandomInt(); But as a contrived example, suppose I wanted to do this: CycleTushKicker( GetRandomInt()); Instead of stepping into CycleTushKicker to figure out how many lickings my kid gets, I'd just like to know the value as soon as I exit GetRandomInt. Is there a way to get this when using C#?

  • looping thru a list of checkboxes and saving the values, not working properly

    - by Erez
    Hello all, I'm having a bit of a problem with this code. The program gives me a list of checkboxes but a user ID. then u user can change his selection and push the save button (id="btnSaveUserIntersts") and i am trying to save in the hidden textbox all the values of the checkboxes that was choosen. The problem is that i am getting all the time the same selections that came form the database and not getting the new selection that the user made. Can any one tell me what am i doing wrong here? $(document).ready( function() { $('#btnSaveUserIntersts').bind( 'click', function() { var strCheckBoxChecked = new String(); $('input[type=checkbox][checked]').each( function() { strCheckBoxChecked += $(this).val(); strCheckBoxChecked += ','; } ); $('#hidUserInterests').val(strCheckBoxChecked); } ); } ); 10x

  • jQuery .get()/.post() doesn't send an updated cookie

    - by Markus
    Hello, I'am doing something like this: function setCookie(name, value, expire) { var exdate = new Date(); exdate.setDate(exdate.getDate()+expire); document.cookie=name+ "=" +escape(value)+((expire==null) ? "" : ";expires="+exdate.toGMTString()); } // When I click a button // Update the cookie setCookie("test", "1"); function getContent() { // Get the data of our new URL $.get("index.php", loadContent); } function loadContent(data) { // alert the new title // the PHP script is changing title after what cookie-value you have alert($("title", data).text()) } First of all, when Iam alerting it is still the last showing up. So I guess it doesn't send the changed cookies at all.. And for some reason I don't see the request in my Live HTTP Headers window... But also, if i request the URL(without the ajax) it works just fine What am I doing wrong here? Regards Markus

  • [jQuery] Any HTML tags inside of tooltip cause basic tooltip to close on hover.

    - by Christian
    Hi. I'm new to jQuery, in fact any kind of AJAX / JavsScript (although not new to PHP, xHTML and CSS). Anyway I'm trying to achieve a "tooltip-like" effect, where I can hover over a div...the new div fades in above it and then when I exit the div the "tooltip" fades out. So here's the basic jQuery I've managed to scrap together reading the odd guide here and there: $(function() { $('#sn-not-logged-in').hover(function() { $('#sn-not-logged-in-hover').fadeIn('medium'); }); $('#sn-not-logged-in-hover').mouseout(function() { $('#sn-not-logged-in-hover').fadeOut('medium'); }); }); Problem is if I put "any" html tag inside the div that hovers in, the second you roll over it the div fades back out. Any ideas how this can be fixed? Cheers.

  • MVC Model architecture

    - by ATT
    I'm getting into CodeIgniter and trying to figure out the good architecture for my models. What kind of models would you create for the following simple example: list page of blog entries: shows part of the entry data, number of comments blog entry page: shows all the entry data, comment list (with part of the comment data) comment page: shows all the comment data I'm trying to get this right so that it's simple and effective. I don't want to load too much information (from the db) on the pages where I don't need them. E.g. should the same entry model handle both multiple entries as well as a single entry? And how should the comments be loaded? I only need the number of comments on the multiple entries (list) page but some of the comment data on the single entry page. How would you handle this?

  • Creating a textarea with auto-resize

    - by DisgruntledGoat
    There was another thread about this, which I've tried. But there is one problem: the textarea doesn't shrink if you delete the content. I can't find any way to shrink it to the correct size - the clientHeight value comes back as the full size of the textarea, not its contents. The code from that page is below. I'd appreciate any help or pointers. function FitToContent(id, maxHeight) { var text = id && id.style ? id : document.getElementById(id); if ( !text ) return; var adjustedHeight = text.clientHeight; if ( !maxHeight || maxHeight > adjustedHeight ) { adjustedHeight = Math.max(text.scrollHeight, adjustedHeight); if ( maxHeight ) adjustedHeight = Math.min(maxHeight, adjustedHeight); if ( adjustedHeight > text.clientHeight ) text.style.height = adjustedHeight + "px"; } } window.onload = function() { document.getElementById("ta").onkeyup = function() { FitToContent( this, 500 ) }; }

  • Order of execution and style of coding in Python

    - by Jason
    Hi guys. I am new to Python so please don't flame me if the question is too basic :) I have read that Python is executed from top - to - bottom. If this is the case, why do programs go like this: def func2(): def func1(): #call func2() def func() #call func1() if __name__ == '__main__': call func() So from what I have seen, the main function goes at last and the other functions are stacked on top of it. Am I wrong in saying this? If no, why isn't the main function or the function definitions written from top to bottom?

  • Elegant way to distinct Path or Entry key

    - by sum1stolemyname
    I have an application loading CAD data (Custom format), either from the local filesystem specifing an absolute path to a drawing or from a database. Database access is realized through a library function taking the drawings identifier as a parameter. the identifiers have a format like ABC 01234T56-T, while my paths a typical windows Paths (eg x:\Data\cadfiles\cadfile001.bin). I would like to write a wrapper function Taking a String as an argument which can be either a path or an identifier which calls the appropriate functions to load my data. Like this: Function CadLoader(nameOrPath : String):TCadData; My Question: How can I elegantly decide wether my string is an idnetifier or a Path to a file? Use A regexp? Or just search for '\' and ':', which are not appearing in the Identifiers?

  • Qt almost same main menu entries

    - by user1671710
    I'm using c++ Qt library and I want to do something which would do : connect(actionB11, SIGNAL(triggered()), this, SLOT(SetSomething(1, 1))); connect(actionB12, SIGNAL(triggered()), this, SLOT(SetSomething(1, 2))); connect(actionB21, SIGNAL(triggered()), this, SLOT(SetSomething(2, 1))); connect(actionB22, SIGNAL(triggered()), this, SLOT(SetSomething(2, 2))); The code above doesnt work because SIGNAL function has to have same number and argument types as SLOT function. Does exist a way how to do it? I dont want to have about 20 function as SetSomething11, SetSomething12 calling SetSomething(1, 1) etc.

  • jquery $.ajax call succeeds but returns nothing. (jsonp)

I checked the firebug 'net' tab and indeed i get a succesful response from the server of "jsonp1272724228884( {} );" Any ideas?

  • Operators vs Functions in C/C++

    - by user356106
    Someone recently asked me the difference between a C++ standard operator (e.g. new,delete,sizeof) and function (e.g. tan,delete, malloc). By "standard" I mean those provided by default by the compiler suite, and not user defined. Below were the answers I gave, though neither seemed satisfactory. (1) An operator doesn't need any headers to be included to use it : E.g. you can have a call to new without including any headers. However, a function (say free() ) does need headers included, compulsorily. (2) An operator is defined as such (ie as a class operator) somewhere in the standard headers. A function isn't. Can you critique these answers and give me a better idea of the difference?

  • Force result for empty() test on an object

    - by hsz
    Hello ! Simple class for example: class Foo { protected $_bar; public function setBar( $value ) { $this->_bar = $value; } } And here is the question: $obj = new Foo(); var_dump( empty( $obj ) ); // true $obj->setBar( 'foobar' ); var_dump( empty( $obj ) ); // false Is it possible to change class's behaviour with testing it with empty() function so it will returns true when object is not filled with data ? I know about magic function __isset( $name ) but it is called only when we test specific field like: empty( $obj->someField ); but not when test whole object.

  • object consisting of jQuery element

    - by Adam Kiss
    hello, current code I've built function to do something over collection of jQuery elements: var collection = $([]); //empty collection I add them with: collection = collection.add(e); and remove with: collection = collection.not(e); It's pretty straightforward solution, works nicely. problem Now, I would like to have an object consisting of various settings set to any jQuery element, i.e.: function addObject(e){ var o = { alpha: .6 //float base: {r: 255, g: 255, b: 255} //color object } e.data('settings', o); } But when I pass jQuery object/element to function (i.e. as e), calling e.data doesn't work, although it would be simplest and really nice solution. question If I have an "collection" of jQuery elements, what is the simplest way of storing some data for each element of set?
