  • Division of text follow the cursor via Javascript/Jquery

    - by webzide
    Dear experts, I wanted have a dynamic division of content follow you with the cursor in the web browser space. I am not a pro at JS so I spent 2 hours to finally debugged a very stupid way to accomplish this. $(document).ready(function () { function func(evt) { var evt = (evt) ? evt : event; var div = document.createElement('div'); div.style.position = "absolute"; div.style.left = evt.clientX + "px"; div.style.top = evt.clientY + "px"; $(div).attr("id", "current") div.innerHTML = "CURSOR FOLLOW TEXT"; $(this).append($(div)); $(this).unbind() $(this).bind('mousemove', function () { $('div').remove("#current"); }); $(this).bind('mousemove', func); } $("body").bind('mousemove', func) }); As you can see this is pretty much Brute force and it slows down the browser quite a bit. I often experience a lag on the browser as a drag my mouse from one place to another. Is there a way to accomplish this easier and faster and more intuitive. I know you can use the cursor image technique but thats something I'm looking to avoid. Thanks in advance.

  • Javascript Anonymous Functions and Global Variables

    - by Jonathan Swift
    I thought I would try and be clever and create a Wait function of my own (I realise there are other ways to do this). So I wrote: var interval_id; var countdowntimer = 0; function Wait(wait_interval) { countdowntimer = wait_interval; interval_id = setInterval(function() { --countdowntimer <=0 ? clearInterval(interval_id) : null; }, 1000); do {} while (countdowntimer >= 0); } // Wait a bit: 5 secs Wait(5); This all works, except for the infinite looping. Upon inspection, if I take the While loop out, the anonymous function is entered 5 times, as expected. So clearly the global variable countdowntimer is decremented. However, if I check the value of countdowntimer, in the While loop, it never goes down. This is despite the fact that the anonymous function is being called whilst in the While loop! Clearly, somehow, there are two values of countdowntimer floating around, but why?

  • Rails partial gets double escaped when using link_to_function

    - by dombesz
    Hi, I have the following code. def add_resume_link(name, form) link_to_function name do |page| html = form.fields_for :resumes, @general_resume.resumes.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial => 'resume_form', :locals=>{:form=>form_parent} end page << "$('resumes').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, id) });" end end And on the resume_form i have somewhere: =add_skill_link("Add Skill", form, "resume_#{id}_skills") and the function looks like: def add_skill_link(name, form, id) link_to_function name do |page| html = form.fields_for :skill_items, @general_resume.skill_items.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial=>'skill_form', :locals=>{:form=>form_parent, :parent=>id} end page << "$('#{id}').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, new Date().getTime()) });" end end So basically i have a javascript code which dinamically adds a piece of html (add_resume) and contains another javascript code which dinamically adds a select box to the page. My problem is that the add_skill_link works fine if i use from the server side, i mean rendering from server side. And gets double escaped when using within the upper described way. I tried to remove the escape_javascript from the add_skill_link bit still not good. Any ideas?

  • Best (Java) book for understanding 'under the bonnet' for programming?

    - by Ben
    What would you say is the best book to buy to understand exactly how programming works under the hood in order to increase performance? I've coded in assembly at university, I studied computer architecture and I obviously did high level programming, but what I really dont understand is things like: -what is happening when I perform a cast -whats the difference in performance if I declare something global as opposed to local? -How does the memory layout for an ArrayList compare with a Vector or LinkedList? -Whats the overhead with pointers? -Are locks more efficient than using synchronized? -Would creating my own array using int[] be faster than using ArrayList -Advantages/disadvantages of declaring a variable volatile I have got a copy of Java Performance Tuning but it doesnt go down very low and it contains rather obvious things like suggesting a hashmap instead of using an ArrayList as you can map the keys to memory addresses etc. I want something a bit more Computer Sciencey, linking the programming language to what happens with the assembler/hardware. The reason im asking is that I have an interview coming up for a job in High Frequency Trading and everything has to be as efficient as possible, yet I cant remember every single possible efficiency saving so i'd just like to learn the fundamentals. Thanks in advance

  • On checkbox checked show radio button

    - by aDameToKillFor
    Hello, I would like to ask for a little help here, since I haven't got any big knowledge in Javascript, nor in jQuery. I need to show 5 radio buttons when a checkbox is checked, the checkboxes represent languages that the user speaks, so for each of the selected, there should appear 5 separate radio buttons for how good they speak it(1 to 5). I tried to do it with jQuery, but I did not manage to get very far away... This is where my checkboxes are created(dynamically): <% for(int i = 0; i < Model.Languages.Count; i++) { %> <input id="applang" name="applang" type="checkbox" value="<%: Model.Languages[i].languageID%>" /> <%: Model.Languages[i].name.ToString() %><br /> <%} %> So, I tried to add this script, but it's not working: <script type="text/javascript"> $("input[@name='applang']").click(function () { $("input[type='radio']").show(); }); I also tried this way - to use this javascript: <script type="text/javascript"> function toggle_visibility(id) { var e = document.getElementById(id); if (e.style.display == 'block') e.style.display = 'none'; else e.style.display = 'block'; } And it works, but it works on already present controls, and I guess I need to create mine dynamically, or maybe not? And I tried to hide a present control with CSS, but then when the script shows it, it is there, only invisible :) Also, I would want to get the name and value of the radio buttons from my database, i.e. Model(this is ASP.NET MVC).. Can someone help me a little bit, please?

  • eclipse error with android: id cannot be resolved or is not a field

    - by Jaynathan Leung
    Hi, I just started playing around with android development, and already with just an attempt at making a button, I have encountered a problem. The error I'm given in the following code is right on "R.id.button1". It says id cannot be resolved or is not a field. Do I need to manually reference every single object I make in the layout xml file? I found that this did work, but it does seem to be a bit much for every button I want to make... package com.example.helloandroid; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class HelloAndroid extends Activity { /** Called when the activity is first created. */ private Button button1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); button1 = (Button)findViewById(R.id.button1); button1.setOnClickListener(new OnClickListener() { public void onClick(View v) { finish(); } }); } }

  • What hash algorithms are parallelizable? Optimizing the hashing of large files utilizing on multi-co

    - by DanO
    I'm interested in optimizing the hashing of some large files (optimizing wall clock time). The I/O has been optimized well enough already and the I/O device (local SSD) is only tapped at about 25% of capacity, while one of the CPU cores is completely maxed-out. I have more cores available, and in the future will likely have even more cores. So far I've only been able to tap into more cores if I happen to need multiple hashes of the same file, say an MD5 AND a SHA256 at the same time. I can use the same I/O stream to feed two or more hash algorithms, and I get the faster algorithms done for free (as far as wall clock time). As I understand most hash algorithms, each new bit changes the entire result, and it is inherently challenging/impossible to do in parallel. Are any of the mainstream hash algorithms parallelizable? Are there any non-mainstream hashes that are parallelizable (and that have at least a sample implementation available)? As future CPUs will trend toward more cores and a leveling off in clock speed, is there any way to improve the performance of file hashing? (other than liquid nitrogen cooled overclocking?) or is it inherently non-parallelizable?

  • PowerPoint PlugIn does not read defaults from .dll.config file

    - by Nick T
    I'm working on a very simple PowerPoint plugin, and I'm quite a bit stumped. In my settings.settings file, I have configured a setting "StartPath", which references where the PowerPoint plugin will navigate to using a Browser component. After I compile the application, and run the installer generated by the Setup project, the application is installed and uses the default value in the settings file. However, if I edit the application.dll.config file, the plugin still uses the old values. How can I set things up such that the plugin references the .dll.config file and not its default settings? The code to access the settings is listed below, including the other variants I have tried: //Attempt 1 string location = MyApplication.Properties.Settings.Default.StartPath; //Attempt 2 string location = ConfigurationManager.AppSettings["StartPath"]; //Attempt 3: Configuration element is inaccessible due to its protection level string applicationName = Environment.GetCommandLineArgs()[0] + ".exe"; string exePath = System.IO.Path.Combine(Environment.CurrentDirectory, applicationName); Configuration config = ConfigurationManager.OpenExeConfiguration(exePath); string location = config.AppSettings["StartPath"];

  • Robotlegs: Warning: Injector already has a rule for type

    - by MikeW
    I have a bunch of warning messages like this appear when using Robotlegs/Signals. Everytime this command class executes, which is every 2-3 seconds ..this message displays below If you have overwritten this mapping intentionally you can use "injector.unmap()" prior to your replacement mapping in order to avoid seeing this message. Warning: Injector already has a rule for type "mx.messaging.messages::IMessage", named "". The command functions fine otherwise but I think I'm doing something wrong anyhow. public class MessageReceivedCommand extends SignalCommand { [Inject] public var message:IMessage; ...etc.. do something with message.. } the application context doesnt map IMessage to this command, as I only see an option to mapSignalClass , besides the payload is received fine. Wonder if anyone knows how I might either fix or suppress this message. I've tried calling this as the warning suggests injector.unmap(IMessage, "") but I receive an error - no mapping found for ::IMessage named "". Thanks Edit: A bit more info about the error Here is the signal that I dispatch to the command public class GameMessageSignal extends Signal { public function GameMessageSignal() { super(IMessage); } } which is dispatched from a IPushDataService class gameMessage.dispatch(message.message); and the implementation is wired up in the app context via injector.mapClass(IPushDataService, PushDataService); along with the signal signalCommandMap.mapSignalClass(GameMessageSignal, MessageReceivedCommand); Edit #2: Probably good to point out also I inject an instance of GameMessageSignal into IPushDataService public class PushDataService extends BaseDataService implements IPushDataService { [Inject] public var gameMessage:GameMessageSignal; //then private function processMessage(message:MessageEvent):void { gameMessage.dispatch(message.message); } } Edit:3 The mappings i set up in the SignalContext: injector.mapSingleton(IPushDataService); injector.mapClass(IPushDataService, PushDataService);

  • Sphinx - delimiters

    - by yoda
    Hi, I would like to know if the Sphinx engine works with any delimiters (like commas and periods in normal MySQL). My question comes from the urge, not to use them at all, but to escape them or at least thay they don't enter in conflict when performing MATCH operations with FULLTEXT searches, since I have problems dealing with them in MySQL by default and I would prefer not to be forced to replace those delimiters by any other characters to provide a good set of results. Sorry if I'm saying something stupid, but I don't have experience with Sphinx or other complementary (?) search engines. To give you an example, if I perform a search with "Passat 2.0 TDI" MySQL by default would identify the period in this case as a delimiter and since the "2" and "0" are too short to be considered words by default, the results would be a bit messed up. Is it easy to handle with Sphinx (or other search engine)? I'm open to suggestions. This is for a large project, with probably more than 500.000 possible records (not trivial at all). Cheers!

  • Questions about openid and dotnetauthentication

    - by chobo2
    Hi I am looking into openid and dotnetauthentication library. However I still go some outstanding questions. the id that comes back is that unique for each user? Can I store this id in a database as the userId(currently this field is a primary key and unique identifier) I read that you can try to request information such as email address but you may not give it to you. What happens if you need this information? I think it kinda sucks if I have to popup another field right away and ask for their email address and whatever else fields I need. Sort of seems to defeat the purpose a bit as I always considered a benefit of openid is that you don't have to fill out registration forms. Is it better to only have some predefined choices(google,yahoo,openid,facebook). Then letting them type in their own ones(ie gray out the field to let them type in a url). I am thinking of this because it goes back to point number 2 if they type in a provider that does not give me the information that I need I am then stuck. How do you a log person out? Do you just kill the form authentication ticket?

  • [ASP.NET MVC] Run ajax scripts on page with navigating with ajax?

    - by Oskar Kjellin
    I got a bit of an issue in my ASP.NET MVC project. I have a chat div in the bottom right corner (like facebook), and of course I do not want this to reload when navigating to all my navigation is ajax. The problem I am facing is that I use the following code on the top of the view page: <script type="text/javascript"> $(document).ready(function() { $('#divTS').hide(); $('a#showTS').click(function() { $('#divTS').slideToggle(400); return false; }); }); </script> The problem is that this code is only loaded with ajax and does not seem to fire? I would like to run all scripts in the newly loaded view, just as if I hadn't navigated with ajax. I cannot put this in the site.master as it only loads once and then probably the divs I am trying to hide doesn't exist. Is there a good way to run scripts in the ajax-loaded div?

  • Best way to use Google's hosted jQuery, but fall back to my hosted library on Google fail

    - by Nosredna
    What would be a good way to attempt to load the hosted jQuery at Google (or other Google hosted libs), but load my copy of jQuery if the Google attempt fails? I'm not saying Google is flaky. There are cases where the Google copy is blocked (apparently in Iran, for instance). Would I set up a timer and check for the jQuery object? What would be the danger of both copies coming through? Not really looking for answers like "just use the Google one" or "just use your own." I understand those arguments. I also understand that the user is likely to have the Google version cached. I'm thinking about fallbacks for the cloud in general. Edit: This part added... Since Google suggests using google.load to load the ajax libraries, and it performs a callback when done, I'm wondering if that's the key to serializing this problem. I know it sounds a bit crazy. I'm just trying to figure out if it can be done in a reliable way or not. Update: jQuery now hosted on Microsoft's CDN. http://www.asp.net/ajax/cdn/

  • How should I deal with floating numbers that numbers that can get so small that the become zero

    - by Tristan Havelick
    So I just fixed an interesting bug in the following code, but I'm not sure the approach I took it the best: p = 1 probabilities = [ ... ] # a (possibly) long list of numbers between 0 and 1 for wp in probabilities: if (wp > 0): p *= wp # Take the natural log, this crashes when 'probabilites' is long enough that p ends up # being zero try: result = math.log(p) Because the result doesn't need to be exact, I solved this by simply keeping the smallest non-zero value, and using that if p ever becomes 0. p = 1 probabilities = [ ... ] # a long list of numbers between 0 and 1 for wp in probabilities: if (wp > 0): old_p = p p *= wp if p == 0: # we've gotten so small, its just 0, so go back to the smallest # non-zero we had p = old_p break # Take the natural log, this crashes when 'probabilites' is long enough that p ends up # being zero try: result = math.log(p) This works, but it seems a bit kludgy to me. I don't do a ton of this kind of numerical programming, and I'm not sure if this is the kind of fix people use, or if there is something better I can go for.

  • HMTL5 Anti Aliasing Browser Disable

    - by Tappa Tappa
    I am forced to consider writing a library to handle the fundamental basics of drawing lines, thick lines, circles, squares etc. of an HTML5 canvas because I can't disable a feature embedded in the browser rendering of the core canvas algorithms. Am I forced to build the HTML5 Canvas rendering process from the ground up? If I am, who's in with me to do this? Who wants to change the world? Imagine a simple drawing application written in HTML5... you draw a shape... a closed shape like a rudimentary circle, free hand, more like an onion than a circle (well, that's what mine would look like!)... then imagine selecting a paint bucket icon and clicking inside that shape you drew and expecting it to be filled with a color of your choice. Imagine your surprise as you selected "Paint Bucket" and clicked in the middle of your shape and it filled your shape with color... BUT, not quite... HANG ON... this isn't right!!! On the inside of the edge of the shape you drew is a blur between the background color and your fill color and the edge color... the fill seems to be flawed. You wanted a straight forward "Paint Bucket" / "Fill"... you wanted to draw a shape and then fill it with a color... no fuss.... fill the whole damned inside of your shape with the color you choose. Your web browser has decided that when you draw the lines to define your shape they will be anti-aliased. If you draw a black line for your shape... well, the browser will draw grey pixels along the edges, in places... to make it look like a "better" line. Yeah, a "better" line that **s up the paint / flood fill process. How much does is cost to pay off the browser developers to expose a property to disable their anti-aliasing rendering? Disabling would save milliseconds for their rendering engine, surely! Bah, I really don't want to have to build my own canvas rendering engine using Bresenham line rendering algorithm... WHAT CAN BE DONE... HOW CAN THIS BE CHANGED!!!??? Do I need to start a petition aimed at the WC3???? Will you include your name if you are interested??? UPDATED function DrawLine(objContext, FromX, FromY, ToX, ToY) { var dx = Math.abs(ToX - FromX); var dy = Math.abs(ToY - FromY); var sx = (FromX < ToX) ? 1 : -1; var sy = (FromY < ToY) ? 1 : -1; var err = dx - dy; var CurX, CurY; CurX = FromX; CurY = FromY; while (true) { objContext.fillRect(CurX, CurY, objContext.lineWidth, objContext.lineWidth); if ((CurX == ToX) && (CurY == ToY)) break; var e2 = 2 * err; if (e2 > -dy) { err -= dy; CurX += sx; } if (e2 < dx) { err += dx; CurY += sy; } } }

  • Setting "submit"

    - by user361626
    Driving me a bit nuts this one, have tried alsorts of combination's... At the top of my file I have PHP Code: if (!ISSET ($_POST['submit'])) which tests if the submit has been hit, if not displays the form.... What I'd like to be able to to is generate a link that would be processed directly by the php code that the form would normally be submitted to... (does that make sense ?) so a generated link in the code looks like .. PHP Code: echo '<a href="index.php?submit&s_type=' . $s_type . '&d_height=' . $d_height . '&j_ref=' . $j_ref . '&j_name=' . j_name . '">' . $j_ref . '</a>'; The link generated looks like .. HTML Code: index.php?s_type=partk&d_height=3312&j_ref=AS0001&j_name=j_name I have tried setting "submit" with links like HTML Code: index.php?submit=submit&s_type=partk&d_height=3312&j_ref=AS0001&j_name=j_name index.php?submit&s_type=partk&d_height=3312&j_ref=AS0001&j_name=j_name How do I create a link that sets "submit so it gets processed rather than going through the form ???

  • Game Development: How do you make a story game?

    - by Martijn Courteaux
    Hi, I made already a few simple games: enter a level, get up to the end, continue to the next level. But I'm still wondering how "real" game developers create games with a story. Here are a few things what a story game has (and where I'm wondering about how they make it) : A sequence of places the player have to visit and do there that, that and that. The first time you see a guy, he says just hello. After a few hours game progress, he gives you a hint to go to a specific place. The first time you walk over a bridge nothing happens, a second time: the bridge falls and you will enter a new location under the bridge. The first time you enter a new location, you will get a lot of information from e.g. villagers, etc. Next time nothing happens The last points are a bit three times the same. But, I don't think they have a save-file with a lot of booleans and integers for holding things like: Player did the first time .... Player enters the tenth time that location Player talked for the ###th time to that person etc When I talk about story games, I'm thinking to: The Legend of Zelda (all games of the serie) Okami And this are a few examples of level-in-level-out games: Mario Braid Crayon Physics Thanks

  • Global mouseMove

    - by Jacob Kofoed
    I have made the following javascript to be used in my jQuery based website. What it does, is to move a slider up/down, and scale the item above higher/smaller. Everything works fine, but since the slider is only a few pixels in height, and the move event is a bit slow (it does not trigger for every pixel) so when I move the mouse fast, the slider can't hold on and the mouse get's out of the slider item. The mouseMove event won't be triggered no more since it is bound to the slider. I guess everything could be fixed by setting the mouseMove global to the whole site, but it won't work, or at least I don't know how to make that work. Should it be bound to document, or body? here is my current code for the slider: $.fn.resize = function (itemToResize) { MinSize = 100; MaxSize = 800; pageYstart = 0; sliderMoveing = false; nuskriverHeight = 0; this.mousedown(function(e) { pageYstart=e.pageY; sliderMoveing = true nuskriverHeight = parseFloat((itemToResize).css('height')); }); this.mouseup(function() { sliderMoveing = false }); this.mousemove(function(e) { if (sliderMoveing) { (itemToResize).css('height', (nuskriverHeight + (e.pageY - pageYstart))); if (parseFloat( (itemToResize).css('height')) > MaxSize) { (itemToResize).css('height', MaxSize) }; if (parseFloat( (itemToResize).css('height')) < MinSize) { (itemToResize).css('height', MinSize) }; }; }); }; Thanks for any help, is much appreciated

  • CSS file in a Spring WAR returns a 404

    - by Rachel G.
    I have a J2EE application that I am building with Spring and Maven. It has the usual project structure. Here is a bit of the hierarchy. MyApplication src main webapp WEB-INF layout header.jsp styles main.css I want to include that CSS file in my JSP. I have the following tag in place. <c:url var="styleSheetUrl" value="/styles/main.css" /> <link rel="stylesheet" href="${styleSheetUrl}"> When I deploy the application, the CSS page isn't being located. When I view the page source, the href is /MyApplication/styles/main.css. Looking inside the WAR, there is a /styles/main.css. However, I get a 404 when I try to access the CSS file directly in the browser. I discovered that the reason for the issue was the Dispatcher Servlet mapping. The mapping looks as follows. <servlet-mapping> <servlet-name>Spring MVC Dispatcher Servlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> I imagine the Dispatcher Servlet doesn't know how to handle the CSS request. What is the best way to handle this issue? I would rather not have to change all of my request mappings.

  • Combining JavaScript for Google Analytics with yours. (Asynchronous tracking.)

    - by lorenzo 72
    I have a JavaScript file which is loaded up at the end of my HTML page. Rather than adding the script code for asynchronous tracking for Google in yet another script I would rather combine the two scripts together. So instead of this: <html> ... <script src="myScript.js"> <!-- google analytics --> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-XXXXX-X']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; (document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(ga); })(); </script> </html> I would have that bit of code in the second script tag at the end of my 'myScript.js'. I have not found one place in google documentation where it suggests to combine the script with yours.

  • PC boot: dl register and drive number

    - by kikou
    I read somewhere in the internet that, before jumping to 0x7c00, the BIOS loads into %dl the "drive number" of the booted device. But what is this "drive number"? Each device attached to the computer is assigned a number by the BIOS? If so, how can I know which number is a given device assigned to? Reading GRUB's source code I found when %dl has bits 0x80 and 0x70 set, it overwrites the whole register with 0x80. Why is that? Here is the code: jmp 3f /* grub-setup may overwrite this jump */ testb $0x80, %dl jz 2f 3: /* Ignore %dl different from 0-0x0f and 0x80-0x8f. */ testb $0x70, %dl jz 1f 2: movb $0x80, %dl 1: By the way. Is there any detailed resource on the boot process of PC's in the web? Specially about what the BIOS does before giving the control to the bootloader and also the standard codes used to communicate with it (like that "drive numer"). I was hoping to write my own bootloader and everything I found is a bit too vague, not technical enough to the point of informing of the exact state of the computer when my bootloader starts to run.

  • Fitting Text into an Image

    - by Abs
    Hello all, I have a function which takes in a font (ttf or otf file) and generates an image of text in different fonts. The problem I have is trying to work out how I can make the text fit in the image regardless of the font-size, type of font, and amount of text. I have tried to make the image rectangle variable so that it contains the text of different fonts without cutting a bit of the text since the image is not long or wide enough. Here is the function that I currently have, I have tried using the number of characters to determine the width of the image, but in some cases for some fonts and sizes, it still gets cut off. function generate_image($save_path, $text, $font_path){ $length = strlen($text) * 15; // Create the image $im = imagecreatetruecolor($length, 40); $white = imagecolorallocate($im, 255, 255, 255); $grey = imagecolorallocate($im, 128, 128, 128); $black = imagecolorallocate($im, 0, 0, 0); imagefilledrectangle($im, 0, 0, $length, 40, $white); $font = $font_path; imagettftext($im, 30, 0, 0, 25, $black, $font, $text); if(imagepng($im, $save_path)){ $status = true; }else{ $status = false; } imagedestroy($im); return $status; } Thank you all for any help

  • How to marshal an object and its content (also objects)

    - by Waldo Spek
    I have a question for which I suspect the answer is a bit complex. At this moment I am programming a DLL (class library) in C#. This DLL uses a 3rd party library and therefore deals with 3rd party objects of which I do not have the source code. Now I am planning to create another DLL, which is going to be used in a later stadium in my application. This second DLL should use the 3rd party objects (with corresponding object states) created by the first DLL. Luckily the 3rd party objects extend the MarshalByRefObject class. I can marshal the objects using System.Runtime.Remoting.Marshal(...). I then serialize the objects using a BinaryFormatter and store the objects as a byte[] array. All goes well. I can deserialize and unmarshal in a the opposite way and end up with my original 3rd party objects...so it appears... Nevertheless, when calling methods on my 3rd party deserialized objects I get object internal exceptions. Normally these methods return other 3rd party objects, but (obviously - I guess) now these objects are missing because they weren't serialized. Now my global question: how would I go about marshalling/serializing all the objects which my 3rd party objects reference...and cascade down the "reference tree" to obtain a full and complete serialized object? Right now my guess is to preprocess: obtain all the objects and build my own custom object and serialize it. But I'm hoping there is some other way...

  • Best way to track the stages of a form across different controllers - $_GET or routing

    - by chrisj
    Hi, I am in a bit of a dilemma about how best to handle the following situation. I have a long registration process on a site, where there are around 10 form sections to fill in. Some of these forms relate specifically to the user and their own personal data, while most of them relate to the user's pets - my current set up handles user specific forms in a User_Controller (e.g via methods like user/profile, user/household etc), and similarly the pet related forms are handled in a Pet_Controller (e.g pet/health). Whether or not all of these methods should be combined into a single Registration_Controller, I'm not sure - I'm open to any advice on that. Anyway, my main issue is that I want to generate a progress bar which shows how far along in the registration process each user is. As the urls in each form section can potentially be mapping to different controllers, I'm trying to find a clean way to extract which stage a person is at in the overall process. I could just use the query string to pass a stage parameter with each request, e.g user/profile?stage=1. Another way to do it potentially is to use routing - e.g the urls for each section of the form could be set up to be registration/stage/1, registration/stage/2 - then i could just map these urls to the appropriate controller/method behind the scenes. If this makes any sense at all, does anyone have any advice for me?
