  • How to get/create anonymous method from TRttiMethod?

    - by Heinrich Ulbricht
    I want to handle a TRttiMethod as anonymous method. How could I do this? Here is a simplified example of how I wish things to work: Interface: TMyClass = class public // this method will be acquired via Rtti procedure Foo; // this method shall return above Foo as anonymous method function GetMethodAsAnonymous: TProc; end; Implementation: function TMyClass.GetMethodAsAnonymous: TProc; var Ctx: TRttiContext; RttiType: TRttiType; RttiMethod: TRttiMethod; begin Ctx := TRttiContext.Create; try RttiType := Ctx.GetType(Self.ClassType); RttiMethod := RttiType.GetMethod('Foo'); Result := ??????; // <-- I want to put RttiMethod here - but how? finally Ctx.Free; end; end;

  • Terminate long running thread in thread pool that was created using QueueUserWorkItem(win 32/nt5).

    - by Jake
    I am programming in a win32 nt5 environment. I have a function that is going to be called many times. Each call is atomic. I would like to use QueueUserWorkItem to take advantage of multicore processors. The problem I am having is I only want to give the function 3 seconds to complete. If it has not completed in 3 seconds I want to terminate the thread. Currently I am doing something like this: HANDLE newThreadFuncCall= CreateThread(NULL,0,funcCall,&func_params,0,NULL); DWORD result = WaitForSingleObject(newThreadFuncCall, 3000); if(result == WAIT_TIMEOUT) { TerminateThread(newThreadFuncCall,WAIT_TIMEOUT); } I just spawn a single thread and wait for 3 seconds or it to complete. Is there anyway to do something similar to but using QueueUserWorkItem to queue up the work? Thanks!

  • Simple javascript problem in ie6 and ie7

    - by Jeff Lamb
    I have a very simple function that takes a list of comma separated (x,y) points and imports them into a graph. I have FF, Chrome and IE8 installed. I use IETester to test for IE6 and IE7. // Import Data this.Import = function(data) { alert("Data in: "+data); var d; // Make sure the first and the last are start/ending parenthesis if ( (data[0] != '(') || (data[data.length-1] != ')') ) { alert("After if: "+data[0]+" "+data[data.length-1]); return false; } ... In Chrome, FF and IE8, I don't see the "After if:" alert. In IE6 and IE7, I see the following two alerts: Data in: (52,16),(100,90) After if: undefined undefined The "Data in" alert matches in all browsers. Any ideas?

  • Need to calculate offsetRight in javascript

    - by Dan Bailiff
    I need to calculate the offsetRight of a DOM object. I already have some rather simple code for getting the offsetLeft, but there is no javascript offsetRight property. If I add the offsetLeft and offsetWidth, will that work? Or is there a better way? function getOffsetLeft(obj) { if(obj == null) return 0; var offsetLeft = 0; var tmp = obj; while(tmp != null) { offsetLeft += tmp.offsetLeft; tmp = tmp.offsetParent; } return offsetLeft; } function getOffsetRight(obj) { if (obj == null) return 0; var offsetRight = 0; var tmp = obj; while (tmp != null) { offsetRight += tmp.offsetLeft + tmp.offsetWidth; tmp = tmp.offsetParent; } return offsetRight; }

  • Are there any differences between SQL Server and MySQL when it comes to preventing SQL injection?

    - by Derek Adair
    I am used to developing in PHP/MySQL and have no experience developing with SQL Server. I've skimmed over the PHP MSSQL documentation and it looks similar to MySQLi in some of the methods I read about. For example, with MySQL I utilize the function mysql_real_excape_string(). Is there a similar function with PHP/SQL Server? What steps do I need to take in order to protect against SQL injection with SQL Server? What are the differences between SQL Server and MySQL pertaining to SQL injection prevention? also - is this post accurate? is the escape string character for SQL Server a single quote?

  • Only perform jquery effects/operations on certain pages

    - by Galen
    Up until now i've been dropping all my jquery code right inside the document.ready function. I'm thinking that for certain situations this isnt the best way to go. for example: If i want an animation to perform when a certain page loads what is the best way to go about that. $(document).ready(function() { $("#element_1").fadeIn(); $("#element_2").delay('100').fadeIn(); $("#element_3").delay('200').fadeIn(); }); If this is right inside of document.ready then every time ANY page loads it's going to check each line and look for that element. What is the best way to tell jquery to only perform a chunk of code on a certain page to avoid this issue.

  • Avoiding exceptions when uploading files in laravel

    - by occam98
    I've got a file upload field (attachment1) in a form that may or may not have a file uploaded in it when I process the form in laravel. When I'm trying to process the page, this line generates an exception: Input::upload('attachment1',path('storage').'attachments/'.$name); Here is the text of the exception: Message: Call to a member function move() on a non-object it seems that I need to check in advance to see if 'attachment1' has a file, and I found that the function Input::has_file('attachment1') is supposed to tell me whether or not 'attachment1' has a file, but even when I submit an empty form, it returns true. Also, from reading documentation, it seems that Input::upload is supposed to just return false when trying to upload a non-existant file, so why does it produce this exception instead, and how can I fix it?

  • unable to find an entry point named 'interlockedexchange'

    - by Miki Amit
    Hi , I built an application in c# vs2005 .net . Everything works fine when i run the application in win 32 bit, But when running the application in win 64 it crashes while trying to call the pinvoke interlockedexchange(which is within the kernel32.dll) function . This is the exception : unable to find an entry point named 'interlockedexchange' I didnt find the interlockedexchange function within the kernel32.dll under system32 directory but it was found under the syswow64 directory(in the kernel32.dll) . I guess that the .net runtime is configured to the system32 directory and not to the syswow64 . How is it possible to change this configuration ? Can you think of any other problem that could cause this? any help would be appreciated! thanks , Miki Amit

  • jquery html attribute not working in IE

    - by Gopal
    I am using country and state dropdowns in my form. Whenever the user selects the country in the dropdown, the respective states of the country will populate in the states dropdown. I am populating the states in the dropdown using ajax call. The problem is that the states get populated in Mozilla but it doesnt work in IE. I guess there is some problem in jquery while loading the states in the states dropdown. The jquery code i am using is $('select#edit-country').change(function(e) { $.getJSON("loadContactUsStates",{id: $(this).val(), ajax: 'true'}, function(j){ var options = ''; for (var i = 0; i < j.length; i++) { options += '<option value="' + j[i].optionValue + '">' + j[i].optionDisplay + '</option>'; } <!-----I guess the problem is with the below line------------------> $("select#edit-state").html(options); })//end json });

  • Choosing random action, Flash AS3

    - by esryl
    I have 2 actions in a Flash file that I would like to test for conversion. One is opening a link in a tab/window, the other loading the content in a Colorbox iframe over the page. How do I randomly choose one of the following actions? I currently listen for a click on a button: clickJoin.addEventListener(MouseEvent.CLICK,toJoin); My two actions are: navigateToURL(new URLRequest("http://www.google.com/"), '_blank'); and ExternalInterface.call('$.fn.colorbox({ href: "http://www.google.com/", width:"80%", height:"80%", iframe:true, onLoad:function(){ $("#player").css({"visibility":"hidden"}); }, onClosed:function(){ $("#player").css({"visibility":"visible"}); }}) ');

  • How can I disable multiple links with jQuery?

    - by Samantha J
    I have the following HTML: <a title="Login" data-href="/MyAccount/Access/Login" data-title="Admin" data-entity="n/a" id="loginLink" class="nav-button dialogLink"><b>Login</b></a> <a title="Register" data-href="/MyAccount/Access/Register" data-title="Admin" data-entity="n/a" id="registerLink" class="nav-button dialogLink"><b>Register</b></a> When a user clicks on the #loginLink or #registerLink I would like to disable the link and call a dialog script. I created the following function: $("#loginLink, #registerLink") .click(function () { $('#loginLink').prop('disabled', true); $('#registerLink').prop('disabled', true); dialog(this); }); It calls the dialog correctly but doesn't disable the links and if I click the buttons more than once it calls up more than one dialog box. Is there something I am doing wrong? I can't see why it would not work.

  • random products instead of related products in magento

    - by abnab
    BElow is the function that selects related product of a single product. I wanted it to work in such a way that if there are no related products other random products will be added to the array. Random could be other products of the same category and if there is no procut in the same category we could fetch from other categories. protected function _prepareData() { $product = Mage::registry('product'); /* @var $product Mage_Catalog_Model_Product */ $this->_itemCollection = $product->getRelatedProductCollection() ->addAttributeToSelect('required_options') ->addAttributeToSort('position', Varien_Db_Select::SQL_ASC) ->addStoreFilter() ; if (Mage::helper('catalog')->isModuleEnabled('Mage_Checkout')) { Mage::getResourceSingleton('checkout/cart')->addExcludeProductFilter($this->_itemCollection, Mage::getSingleton('checkout/session')->getQuoteId() ); $this->_addProductAttributesAndPrices($this->_itemCollection); } // Mage::getSingleton('catalog/product_status')->addSaleableFilterToCollection($this->_itemCollection); Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($this->_itemCollection); $this->_itemCollection->load(); foreach ($this->_itemCollection as $product) { $product->setDoNotUseCategoryId(true); } return $this; } Thanks Abnab

  • Select dynamic string has a different value when referenced in Where clause

    - by David
    I dynamically select a string built using another string. So, if string1='David Banner', then MyDynamicString should be 'DBanne' Select ... , Left( left((select top 1 strval from dbo.SPLIT(string1,' ')) //first word ,1) //first character + (select top 1 strval from dbo.SPLIT(string1,' ') //second word where strval not in (select top 1 strval from dbo.SPLIT(string1,' '))) ,6) //1st character of 1st word, followed by up to 5 characters of second word [MyDynamicString] ,... From table1 Join table2 on table1pkey=table2fkey Where MyDynamicString <> table2.someotherfield I know table2.someotherfield is not equal to the dynamic string. However, when I replace MyDynamicString in the Where clause with the full left(left(etc.. function, it works as expected. Can I not reference this string later in the query? Do I have to build it using the left(left(etc.. function each time in the where clause?

  • Python: Filter a dictionary

    - by Adam Matan
    Hi, I have a dictionary of points, say: >>> points={'a':(3,4), 'b':(1,2), 'c':(5,5), 'd':(3,3)} I want to create a new dictionary with all the points whose x and y value is smaller than 5, i.e. points 'a', 'b' and 'd'. According to the the book, each dictionary has the items() function, which returns a list of (key, pair) tuple: >>> points.items() [('a', (3, 4)), ('c', (5, 5)), ('b', (1, 2)), ('d', (3, 3))] So I have written this: >>> for item in [i for i in points.items() if i[1][0]<5 and i[1][1]<5]: ... points_small[item[0]]=item[1] ... >>> points_small {'a': (3, 4), 'b': (1, 2), 'd': (3, 3)} Is there a more elegant way? I was expecting Python to have some super-awesome dictionary.filter(f) function... Adam

  • How to smooth an image loaded with FileReference?

    - by Lost_in_code
    Been trying to smooth images loaded with FileReferece with no luck. Below is the code I'm using: fileRef = new FileReference(); fileRef.addEventListener(Event.COMPLETE, fileLoaded); private function fileLoaded(e:Event):void{ var ldr:Loader = new Loader(); ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, function(e:Event):void{ var bm:Bitmap = Bitmap(e.target.content as Bitmap); bm.smoothing = true; img.load(bm) }); ldr.loadBytes(fileRef.data); } <custom:SWFLoaderAdvanced id="img"/> bm.smoothing should've smoothened the loaded image, but for some reason it doesn't. Am I missing something here? Note: SWFLoaderAdvanced automatically smoothens any image that's loaded inside it. It works perfectly with loaded images other than the ones loaded with FileReference.

  • Phantomjs creating black output from SVG using page.render

    - by Neil Young
    I have been running PhantomJS 1.9.6 happily on a turnkey Linux server for about 4 months now. Its purpose is to take an SVG file and create different sizes using the page.render function. This has been doing this but since a few days ago has started to generate a black mono output. Please see below: The code: var page = require('webpage').create(), system = require('system'), address, output, ext, width, height; if ( system.args.length !== 4 ) { console.log("{ \"result\": false, \"message\": \"phantomjs.rasterize: error need address, output, extension arguments\" }"); //console.log('phantomjs.rasterize: error need address, output, extension arguments'); phantom.exit(1); } else if( system.args[3] !== "jpg" && system.args[3] !== "png"){ console.log("{ \"result\": false, \"message\": \"phantomjs.rasterize: error \"jpg\" or \"png\" only please\" }"); //console.log('phantomjs.rasterize: error "jpg" or "png" only please'); phantom.exit(1); } else { address = system.args[1]; output = system.args[2]; ext = system.args[3]; width = 1044; height = 738; page.viewportSize = { width: width, height: height }; //postcard size page.open(address, function (status) { if (status !== 'success') { console.log("{ \"result\": false, \"message\": \"phantomjs.rasterize: error loading address ["+address+"]\" }"); //console.log('phantomjs.rasterize: error loading address ['+address+'] '); phantom.exit(); } else { window.setTimeout(function () { //--> redner full size postcard page.render( output + "." + ext ); //--> redner smaller postcard page.zoomFactor = 0.5; page.clipRect = {top:0, left:0, width:width*0.5, height:height*0.5}; page.render( output + ".50." + ext); //--> redner postcard thumb page.zoomFactor = 0.25; page.clipRect = {top:0, left:0, width:width*0.25, height:height*0.25}; page.render( output + ".25." + ext); //--> exit console.log("{ \"result\": true, \"message\": \"phantomjs.rasterize: success ["+address+"]>>["+output+"."+ext+"]\" }"); //console.log('phantomjs.rasterize: success ['+address+']>>['+output+'.'+ext+']'); phantom.exit(); }, 100); } }); } Does anyone know what can be causing this? There have been no server configuration changes that I know of. Many thanks for your help.

  • IE7 resize problems

    - by moshe_ravid
    i have a page that contains content which need to be dynamically changed according to the current page size. in order to do that, during the onload event, i attach some JS function to the "onresize" window event. it looks like that: window.onresize = function() { //do something here... }; This is working fine in any browse, except IE7! These are the problems i'm having: It seems that in IE7, when i resize the window vertically only (i.e. clicking with the mouse on the bottom border, and drag it down), it does not fire the "onresize" event. sometimes, i get an infinite loop of "onresize" event, causing the browser to hang forever. I will appreciate any help with any of these issues. thanks, Moe

  • Zend_Test_PHPUnit_ControllerTestCase: Test view parameters and not rendered output

    - by erenon
    Hi, I'm using Zend_Test_PHPUnit_ControllerTestCase to test my controllers. This class provides various ways to test the rendered output, but I don't want to get my view scripts involved. I'd like to test my view's vars. Is there a way to access to the controllers view object? Here is an example, what I'm trying to do: <?php class Controller extends Zend_Controller_Action { public function indexAction() { $this-view->foo = 'bar'; } } class ControllerTest extends Zend_Test_PHPUnit_ControllerTestCase { public function testShowCallsServiceFind() { $this->dispatch('/controller'); //doesn't work, there is no such method: $this->assertViewVar('foo', 'bar'); //doesn't work: $this-assertEquals( 'bar', $this->getView()->foo ); } }

  • Permutations of Varying Size

    - by waiwai933
    I'm trying to write a function in PHP that gets all permutations of all possible sizes. I think an example would be the best way to start off: $my_array = array(1,1,2,3); Possible permutations of varying size: 1 1 // * See Note 2 3 1,1 1,2 1,3 // And so forth, for all the sets of size 2 1,1,2 1,1,3 1,2,1 // And so forth, for all the sets of size 3 1,1,2,3 1,1,3,2 // And so forth, for all the sets of size 4 Note: I don't care if there's a duplicate or not. For the purposes of this example, all future duplicates have been omitted. What I have so far in PHP: function getPermutations($my_array){ $permutation_length = 1; $keep_going = true; while($keep_going){ while($there_are_still_permutations_with_this_length){ // Generate the next permutation and return it into an array // Of course, the actual important part of the code is what I'm having trouble with. } $permutation_length++; if($permutation_length>count($my_array)){ $keep_going = false; } else{ $keep_going = true; } } return $return_array; } The closest thing I can think of is shuffling the array, picking the first n elements, seeing if it's already in the results array, and if it's not, add it in, and then stop when there are mathematically no more possible permutations for that length. But it's ugly and resource-inefficient. Any pseudocode algorithms would be greatly appreciated. Also, for super-duper (worthless) bonus points, is there a way to get just 1 permutation with the function but make it so that it doesn't have to recalculate all previous permutations to get the next? For example, I pass it a parameter 3, which means it's already done 3 permutations, and it just generates number 4 without redoing the previous 3? (Passing it the parameter is not necessary, it could keep track in a global or static). The reason I ask this is because as the array grows, so does the number of possible combinations. Suffice it to say that one small data set with only a dozen elements grows quickly into the trillions of possible combinations and I don't want to task PHP with holding trillions of permutations in its memory at once.
