  • Reflection, invoke

    - by Alaa'
    Hi, I have a dll file, and i took an object from it and called the functions inside this dll by the object, like this way: Command testClass = (Command)assembly.CreateInstance(creatObject); testClass.Execute(); anyway, the i used reflection from some reason. so i need to use invoke function & set values for variables, then calling the basic function Execute. Before: i wrote the following: object returnValue = objectType.GetMethod("setValues").Invoke(classObject, arguments); testClass.Execute(); but it wasnt useful for me. i used the following: object returnValue = objectType.GetMethod("setValues").Invoke(classObject, arguments); object returnValue1 = objectType.GetMethod("Execute").Invoke(classObject, null); i just want to ask if this is right, to calling the execute in this way, and by the way it works! Thank you.

  • How to expose a Delphi set type via Soap

    - by Wouter van Nifterick
    I'm currently creating soap wrappers for some Delphi functions so that we can easily use them from PHP, C# and Delphi. I wonder what's the best way to expose sets. type TCountry = (countryUnknown,countryNL,countryD,countryB,countryS,countryFIN,countryF,countryE,countryP,countryPl,countryL); TCountrySet = set of TCountry; function GetValidCountrySet(const LicensePlate:string; const PossibleCountriesSet:TCountrySet):TCountrySet; I'm currently wrapping it like this for the soap server: type TCountryArray = array of TCountry; function TVehicleInfo.GetValidCountrySet(const LicensePlate:string; const PossibleCountriesSet:TCountryArray):TCountryArray; It works, but I need to write a lot of useless and ugly code to convert sets--arrays and arrays--sets. Is there an easier, more elegant, or more generic way to do this?

  • jQuery Tabs - Following External Links

    - by Ricky
    I have jQuery Tabs setup, but am trying to get a Tab to follow an external link. I have tried to use the code from jQuery, but the URL still loads via Ajax instead of redirecting the browser to the url: http://jqueryui.com/demos/tabs/#...follow_a_tab.27s_URL_instead_of_loading_its_content_via_ajax Current code: $(function() { $('#rotate > ul').tabs({ select: function(event, ui) { var url = $.data(ui.tab, 'load.tabs'); if( url ) { location.href = url; return false; } return true; } }); });

  • How to update a table row with save button using .ajax

    - by Randall
    I have a table which has one row and only one cell will be editable. I have accomplished this with the following code. $("td#effEndDate").click(function() { if (!$(this).hasClass("edit")) { var value = jQuery.trim($(this).html()); $(this).html("<input id=\"txtEdit\" type=\"text\" value=\"" + value + "\" />"); $(this).addClass("edit"); $("#txtEdit").focus(); } }); Now this is the part where i'm stuck. After the field is updated a save button must be clicked to call the proper .ajax method to update the database. But how can I compare the previous value to the current value on a button press? Since i'm not using the onblur property where I could have saved the old value and passed it to the update function.

  • how do arguments work with dojo.connect?

    - by sprugman
    I've read the docs, but I must be missing something. I've got a grid, I want to connect to the event that fires when the column headers are clicked for sorting, thus: dojo.addOnLoad(function(){ var grid = dijit.byId("grid"); dojo.connect(grid, "setSortInfo", 'afterSort'); }); function afterSort() { console.info('after sort'); } That works fine as far as it goes. I know the setSortInfo method has an argument which is the column number. How do I get that value? I've tried putting a parameter in the sig for afterSort to no avail. The docs say "the method receives the same arguments as the event", but where are they???

  • An IOCP documentation interpretation question - buffer ownership ambiguity

    - by Poni
    Since I'm not a native English speaker I might be missing something so maybe someone here knows better than me. Taken from WSASend's doumentation at MSDN: lpBuffers [in] A pointer to an array of WSABUF structures. Each WSABUF structure contains a pointer to a buffer and the length, in bytes, of the buffer. For a Winsock application, once the WSASend function is called, the system owns these buffers and the application may not access them. This array must remain valid for the duration of the send operation. Ok, can you see the bold text? That's the unclear spot! I can think of two translations for this line (might be something else, you name it): Translation 1 - "buffers" refers to the OVERLAPPED structure that I pass this function when calling it. I may reuse the object again only when getting a completion notification about it. Translation 2 - "buffers" refer to the actual buffers, those with the data I'm sending. If the WSABUF object points to one buffer, then I cannot touch this buffer until the operation is complete. Can anyone tell what's the right interpretation to that line? And..... If the answer is the second one - how would you resolve it? Because to me it implies that for each and every data/buffer I'm sending I must retain a copy of it at the sender side - thus having MANY "pending" buffers (in different sizes) on an high traffic application, which really going to hurt "scalability". Statement 1: In addition to the above paragraph (the "And...."), I thought that IOCP copies the data to-be-sent to it's own buffer and sends from there, unless you set SO_SNDBUF to zero. Statement 2: I use stack-allocated buffers (you know, something like char cBuff[1024]; at the function body - if the translation to the main question is the second option (i.e buffers must stay as they are until the send is complete), then... that really screws things up big-time! Can you think of a way to resolve it? (I know, I asked it in other words above).

  • How do you draw a line from one corner of the stage to the other?

    - by George Edison
    I am completely perplexed. I asked this question and it (any mentioned solution) doesn't seem to be working at all. All I want is to draw a line from one corner to the other. Here again is the link to the SWF file I have (it's embedded in an HTML document): test.html Here is the source: package { import flash.display.Sprite; import flash.events.Event; public class Main extends Sprite { public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); // entry point graphics.clear(); graphics.lineStyle(10, 0x000000); graphics.moveTo(0, 0); graphics.lineTo(stage.stageWidth, stage.stageHeight); } } } It just doesn't work! The line goes from somewhere offscreen to about the middle of the stage. What on earth am I doing wrong?

  • Code Profiling in the Windows Sidebar Environment

    - by Matt
    Does anyone know of a way I can code-profile my Windows Sidebar Gadget? I've played around with the code-profiling tool in IE8's "Developer Tools" and the code-profiling included in Visual Studio 2010, but I can't find a way to include the System.* API, which my gadget relies on (as it is standard in the Sidebar environment). The gadget also relies on cross-domain AJAX requests; which is normally permitted in the Sidebar environment. By code-profiling I primarily mean: Function call count Function execution time Any ideas would be much appreciated. Regards, Matt

  • 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.

  • Statistics: combinations in Python

    - by Morlock
    I need to compute combinatorials (nCr) in Python but cannot find the function to do that in 'math', 'numyp' or 'stat' libraries. Something like a function of the type: comb = calculate_combinations(n, r) I need the number of possible combinations, not the actual combinations, so itertools.combinations does not interest me. Finally, I want to avoid using factorials, as the numbers I'll be calculating the combinations for can get to big and the factorials are going to be monstruous. This seems like a REALLY easy to answer question, however I am being drowned in questions about generating all the actual combinations, which is not what I want. :) Many thanks

  • calling facebox in a google maps balloon

  • KO 2.3.4 - Accessing validation array from callbacks in models

    - by kenny99
    Hi, Apologies if this is an oversight or sheer stupidity on my part but I can't quite figure out how to access the validation array from a callback in a model (using ORM and KO 2.3.4). I want to be able to add specific error messages to the validation array if a callback returns false. e.g This register method: public function register(array & $array, $save = FALSE) { // Initialise the validation library and setup some rules $array = Validation::factory($array) ->pre_filter('trim') ->add_rules('email', 'required', 'valid::email', array($this, 'email_available')) ->add_rules('confirm_email', 'matches[email]') ->add_rules('password', 'required', 'length[5,42]') ->add_rules('confirm_password', 'matches[password]'); return ORM::validate($array, $save); } Callback: public function email_available($value) { return ! (bool) $this->db ->where('email', $value) ->count_records($this->table_name); } I can obviously access the current model from the callback, but I was wondering what the best way to add custom error from the callback would be?

  • How do I write to a file and print to a terminal cuncurrently in Unix?

    - by bias
    I have a little bash function to log my Macports outputs to a file (since installs often spew little tidbits that are easy to lose in terminal noise), then I just cat the file to the terminal: function porti { command sudo port install $@ >> $1.log 2>&1; cat $1.log } Is there a way to do this concurrently? I don't care about it being in Bash, that's just how I started it. BTW I pass $@ to install but only $1 for the file name so that I can do something like: porti git-gore +bash_completion and only get the file git-core.log however someone else might prefer to include variants in the file name ...

  • Flash AS3 - Display an error if the XML if incorrect

    - by ongoingworlds
    Hi, I'm creating a flash application which loads in some XML which is generated dynamically from the CMS. I want to display an error in case the XML file isn't formatted correctly. When I test this with incorrectly formatted XML, it will just get to the line myXML = XML(myLoader.data); and then just bomb out. How can I catch the error, display a message to the user, but the flash program to continue as normal. var myXMLURL:URLRequest = new URLRequest(XMLfile); var myLoader:URLLoader = new URLLoader(myXMLURL); myLoader.addEventListener(Event.COMPLETE, xmlLoaded); myLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlFailed); var myXML:XML; //--when the xml is loaded, do this function xmlLoaded(e:Event):void { myXML = XML(myLoader.data); trace("XML = "+myXML); } //--if the xml fails to load, do this function xmlFailed(event:IOErrorEvent):void { errorMsg.text = "The XML file cannot be found" }

  • Problem with type coercion and string concatenation in JavaScript in Greasemonkey script on Firefox

    - by Yi Jiang
    I'm creating a GreaseMonkey script to improve the user interface of the 10k tools Stack Overflow uses. I have encountered an unreproducible and frankly bizarre problem that has confounded me and the others in the JavaScript room on SO Chat. We have yet to find the cause after several lengthy debugging sessions. The problematic script can be found here. Source - Install The problem occurs at line 85, the line after the 'vodoo' comment: return (t + ' (' + +(+f.offensive + +f.spam) + ')'); It might look a little weird, but the + in front of the two variables and the inner bracket is for type coercion, the inner middle + is for addition, and the other ones are for concatenation. Nothing special, but observant reader might note that type coercion on the inner bracket is unnecessary, since both are already type coerced to numbers, and type coercing result is useless when they get concatenated into a string anyway. Not so! Removing the + breaks the script, causing f.offensive and f.spam to be concatenated instead of added together. Adding further console.log only makes things more confusing: console.log(f.offensive + f.spam); // 50 console.log('' + (+f.offensive + +f.spam)); // 5, but returning this yields 50 somehow console.log('' + (+f.offensive + +f.spam) + ''); // 50 Source: http://chat.stackoverflow.com/transcript/message/203261#203261 The problem is that this is unreproducible - running scripts like console.log('a' + (+'3' + +'1') + 'b'); in the Firebug console yields the correct result, as does (function(){ return 'a' + (+'3' + +'1') + 'b'; })(); Even pulling out large chunks of the code and running them in the console does not reproduce this bug: $('.post-menu a[id^=flag-post-]').each(function(){ var f = {offensive: '4', spam: '1'}; if(f){ $(this).text(function(i, t){ // Vodoo - please do not remove the '+' in front of the inner bracket return (t + ' (' + +(+f.offensive + +f.spam) + ')'); }); } }); Tim Stone in the chatroom has reproduction instruction for those who are below 10k. This bug only appears in Firefox - Chrome does not appear to exhibit this problem, leading me to believe that this may be a problem with either Firefox's JavaScript engine, or the Greasemonkey add-on. Am I right? I can be found in the JavaScript room if you want more detail and/or want to discuss this.

  • Windows disassembler: looking for a tool...

    - by SigTerm
    Hello. I'm looking for a (preferably free) tool that can produce "proper" disassembly listing from a (non-.NET) windows PE file (*.exe or *.dll). Important requirement: it should be possible to run the listing through a windows assembler (nasm, masm or whatever) and get working exe again (not necessarily identical to original one, but it should behave in the same way). Intended usage is adding new subroutines into existing code, when source is not available. Ideally, tool should be able to detect function/segment boundaries, API calls, and generate proper labels for jumps (I can live without labels for loops/jumps, though, but function boundary detection would be nice), and keep program resources/segments in place. I'm already aware of IdaPRO(not free), OllyDBG (useful for in-place hacking, doesn't generate disassembly listing, AFAIK), ndisasm (output isn't suitable for assembler), dumpbin (useful, but AFAIK, output isn't suitable for assembler) and "proxy dll" technique. Ideas? Or maybe there is a book/tutorial that explains some kind of alternative approach?

  • Confusion regarding laziness

    - by Abhinav Kaushik
    I have a function myLength = foldl (\ x _ -> x + 1) 0 which fails with stack overflow with input around 10^6 elements (myLength [1..1000000] fails). I believe that is due to the thunk build up since when I replace foldl with foldl', it works. So far so good. But now I have another function to reverse a list : myReverse = foldl (\ acc x -> x : acc) [] which uses the lazy version foldl (instead of foldl') When I do myLength . myReverse $ [1.1000000]. This time it works fine. I fail to understand why foldl works for the later case and not for former?
