• Obfuscator for .NET assembly (Maybe just a C++ obfuscator?)

  - by Pirate for Profit

  The software company I work for is using a ton of open source LGPL/BSD/MIT C++ code that we have written wrappers around to port "helper classes" into a .NET assembly, via C++/CLI. These libraries have wrapped old cryptic APIs into easy-to-use ones based on common sense, and will be very helpful for a lot of different tasks will be included in many future client's applications, and we might even license it to other software companies in the same field. So naturally we are tasked with looking into solutions for securing the code from prying eyes. What we're trying to do is stop the casual observer from seeing what's going on. Now I have hacked some crazy shit in EverQuest and other video games in my day so I know with enough tireless effort anything can be done. But we don't want to make it easy for whomever. To the point, besides the Visual Studio compiler's optimizations, is there's a C++ obfuscator or .NET assembly obfuscator (after it's been built o.O) or something that would scramble everything up, re-arrange data structures, string constants, etc. idk? And if such a thing exists, we'd be curious to know how that would impact performance, as some sections of code are time critical (funny saying that using a managed M$ framework).

• AudioRecord - empty buffer

  - by Arxas

  I' m trying to record some audio using AudioRecord class. Here is my code: int audioSource = AudioSource.MIC; int sampleRateInHz = 44100; int channelConfig = AudioFormat.CHANNEL_IN_MONO; int audioFormat = AudioFormat.ENCODING_PCM_16BIT; int bufferSizeInShorts = 44100; int bufferSizeInBytes = 2*bufferSizeInShorts; short Data[] = new short[bufferSizeInShorts]; Thread recordingThread; AudioRecord audioRecorder = new AudioRecord(audioSource, sampleRateInHz, channelConfig, audioFormat, bufferSizeInBytes); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } public void startRecording(View arg0) { audioRecorder.startRecording(); recordingThread = new Thread(new Runnable() { public void run() { while (Data[bufferSizeInShorts-1] == 0) audioRecorder.read(Data, 0, bufferSizeInShorts); } }); audioRecorder.stop(); } Unfortunately my short array is empty after the recording is over. May I kindly ask you to help me figure out what's wrong?

• Anchors with overlapping divs

  - by tmdelane

  I am using a grid based layout, with two main sections. Graph and Timeline. Graph, contains graded vertical bars, HTML similar to: <div id="graph" class="container_160"> <div id="Jan-97" class="grid_1 major"><a href="#">&nbsp;</a></div> <div id="Feb-97" class="grid_1 minor"><a href="#">&nbsp;</a></div> <div id="Mar-97" class="grid_1 minor"><a href="#">&nbsp;</a></div> <div id="Apr-97" class="grid_1 minor"><a href="#">&nbsp;</a></div> <div id="May-97" class="grid_1 minor"><a href="#">&nbsp;</a></div> etc... </div> Timeline, contains horizontal bars, HTML similar to: <div id="timeline" class="container_160"> <div id="bar1" class="grid_32 suffix_128"><a href="#">&nbsp;</a></div> <div id="bar2" class="prefix_32 grid_24 suffix_104"><a href="#">&nbsp;</a></div> <div id="bar3" class="prefix_58 grid_7 suffix_95"><a href="#">&nbsp;</a></div> </div> Timeline is relatively positioned to Graph so that it overlaps. My problem is that when these divs overlap, the anchors in Timeline stop working. I am open to both CSS and Jquery solutions. Thanks in advance. t.

• form submit button moves cutting image

  - by flavour404

  Hi I have a submit button and am styling it using the following css: .subm { background-color:Transparent; background-image:url(Images/Button_Send.png); background-repeat:no-repeat; width:82px; height:30px; display:block; border:none; outline:none; overflow:visible;} .subm:hover { background-color:Transparent; background-image:url(Images/Button_Send_Over.png); background-repeat:no-repeat; width:82px; height:30px; display:block; border:none; outline:none; overflow:visible; } Here is the html: <input type="submit" class="subm" value="" /> Nothing surprising. However, what annoys me is that when the submit button is clicked in IE it moves the image up a couple of pixels cutting them off which makes it look, hmm, good word, 'naff.' How can I compensate or stop this? I have tried expanding the image and leaving a couple of blank pixels at the top but it still does the same thing! Thanks R.

• Stuck in a loop

  - by Luke

  while (true) { //read in the file StreamReader convert = new StreamReader("../../convert.txt"); //define variables string line = convert.ReadLine(); double conversion; int numberIn; double conversionFactor; //ask for the conversion information Console.WriteLine("Enter the conversion in the form (Amount, Convert from, Convert to)"); String inputMeasurement = Console.ReadLine(); string[] inputMeasurementArray = inputMeasurement.Split(','); //loop through the lines looking for a match while (line != null) { string[] fileMeasurementArray = line.Split(','); if (fileMeasurementArray[0] == inputMeasurementArray[1]) { if (fileMeasurementArray[1] == inputMeasurementArray[2]) { Console.WriteLine("The conversion factor for {0} to {1} is {2}", inputMeasurementArray[1], inputMeasurementArray[2], fileMeasurementArray[2]); //convert to int numberIn = Convert.ToInt32(inputMeasurementArray[0]); conversionFactor = Convert.ToDouble(fileMeasurementArray[2]); conversion = (numberIn * conversionFactor); Console.WriteLine("{0} {1} is {2} {3} \n", inputMeasurementArray[0], inputMeasurementArray[1], conversion, inputMeasurementArray[2]); break; } } else { Console.WriteLine("Please enter two valid conversion types \n"); break; } line = convert.ReadLine(); } } The file consists of the following: ounce,gram,28.0 pound,ounce,16.0 pound,kilogram,0.454 pint,litre,0.568 inch,centimetre,2.5 mile,inch,63360.0 The user will input something like 6,ounce,gram The idea is that it finds the correct line by checking if the first and second words in the file are the same as the second and third the user enters. The problem is that if it checks the first line and it fails the if statement, if goes through to the else statement and stops. I am trying to find a way where it will stop after the it finds the correct line but not until. If someone types in a value that isn't in the file, then it should show an error.

• Problem: Movie Clip contains just one frame

  - by Doug

  I'm a newbie at Flash, so started playing with a pretty standard code sample: one layer contains a movie clip with a flying rectangle, another layer has a button to control it. All script code is in Main.as file. The rectangle was named square1 through the Property window. Here is the problem: the constructor for Main has a line: square1.stop(); to prevent clip from playing, but it doesn't help - it plays. I know the constructor fires, because it has trace("stuff") in it. The code does check that the stage has been created. What strange is that square1.currentFrame always returns 1, and square1.totalFrames returns 1 as well. The layer has 24 frames on the timeline. I tried a tween with just 2 keyframes, then converted whole tween into frames - same result. I mean, the thing is flying before my eyes, how can it be 1 frame??? I even added a listener: square1.addEventListener(Event.ENTER_FRAME, onFrameChange); The event fires all the time, i.e. the frames change, but currentFrame is still 1. Also, tried to name individual frames and use square1.gotoAndStop("begin") and stuff like that. Nothing helps. I am really stuck with this stupid problem.

• EF in a UserControl can't see the app.config?

  - by Sven

  I just created a user control. This control also makes use of my static Entity Framework class to load two comboboxes. All is well and runs without a problem. Design and runtime are working. Then when I stop the application all the forms that contain my UserControl don't work any more in design time. I just see two errors: Error1: The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid. Error 2: The variable ccArtikelVelden is either undeclared or was never assigned. (ccArtikelVelde is my UserControl) Runtime everything is still working My static EF Repositoy class: public class BSManagerData { private static BSManagerEntities _entities; public static BSManagerEntities Entities { get { if (_entities == null) _entities = new BSManagerEntities(); return _entities; } set { _entities = value; } } } Some logic happening in my UserControl to load the data in the comboboxes: private void LaadCbx() { cbxCategorie.DataSource = (from c in BSManagerData.Entities.Categories select c).ToList(); cbxCategorie.DisplayMember = "Naam"; cbxCategorie.ValueMember = "Id"; } private void cbxCategorie_SelectedIndexChanged(object sender, EventArgs e) { cbxFabrikant.DataSource = from f in BSManagerData.Entities.Fabrikants where f.Categorie.Id == ((Categorie)cbxCategorie.SelectedItem).Id select f; cbxFabrikant.DisplayMember = "Naam"; cbxFabrikant.ValueMember = "Id"; } The only way to make my forms work again, design time, is to comment out the EF part in the UserControl (see above) and rebuild. It's very strange, everything is in the same assembly, same namespace (for the sake of simplicity). Anyone an idea?

• Invalid table view update with insertRowsAtIndexPaths:

  - by Crystal

  I'm having trouble with insertRowsAtIndexPaths:. I'm not quite sure how it works. I watched the WWDC 2010 video on it, but I'm still getting an error. I thought I was supposed to update the model, then wrap the insertRowsAtIndexPaths: in the tableView beginUpdates and endUpdates calls. What I have is this: self.customTableArray = (NSMutableArray *)sortedArray; [_customTableView beginUpdates]; [tempUnsortedArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { [sortedArray enumerateObjectsUsingBlock:^(id sortedObj, NSUInteger sortedIdx, BOOL *sortedStop) { if ([obj isEqualToString:sortedObj]) { NSIndexPath *newRow = [NSIndexPath indexPathForRow:sortedIdx inSection:0]; [_customTableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newRow] withRowAnimation:UITableViewRowAnimationAutomatic]; *sortedStop = YES; } }]; }]; [_customTableView endUpdates]; customTableArray is my model array. sortedArray is just the sorted version of that array. When I run this code when I hit my plus button to add a new row, I get this error: Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (2) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (2 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).' I'm not sure what I'm doing wrong. Thoughts? Thanks.

• Problem deleting .svn directories on Windows XP

  - by John L

  I don't seem to have this problem on my home laptop with Windows XP, but then I don't do much work there. On my work laptop, with Windows XP, I have a problem deleting directories when it has directories that contain .svn directories. When it does eventually work, I have the same issue emptying the Recycle bin. The pop-up window says "Cannot remove folder text-base: The directory is not empty" or prop-base or other folder under .svn This continued to happen after I changed config of TortoiseSVN to stop the TSVN cache process from running and after a reboot of the system. Multiple tries will eventually get it done. But it is a huge annoyance because there are other issues I'm trying to fix, so I'm hoping it is related. 'Connected Backup PC' also runs on the laptop and the real problem is that cygwin commands don't always work. So I keep thinking the dot files and dot directories have something to do with both problems and/or the backup or other process scanning the directories is doing it. But I've run out of ideas of what to try or how to identify the problem further.

• How to cancel a deeply nested process

  - by Mystere Man

  I have a class that is a "manager" sort of class. One of it's functions is to signal that the long running process of the class should shut down. It does this by setting a boolean called "IsStopping" in class. public class Foo { bool isStoping void DoWork() { while (!isStopping) { // do work... } } } Now, DoWork() was a gigantic function, and I decided to refactor it out and as part of the process broke some of it into other classes. The problem is, Some of these classes also have long running functions that need to check if isStopping is true. public class Foo { bool isStoping void DoWork() { while (!isStopping) { MoreWork mw = new MoreWork() mw.DoMoreWork() // possibly long running // do work... } } } What are my options here? I have considered passing isStopping by reference, which I don't really like because it requires there to be an outside object. I would prefer to make the additional classes as stand alone and dependancy free as possible. I have also considered making isStopping a property, and then then having it call an event that the inner classes could be subscribed to, but this seems overly complex. Another option was to create a "Process Cancelation Token" class, similar to what .net 4 Tasks use, then that token be passed to those classes. How have you handled this situation? EDIT: Also consider that MoreWork might have a EvenMoreWork object that it instantiates and calls a potentially long running method on... and so on. I guess what i'm looking for is a way to be able to signal an arbitrary number of objects down a call tree to tell them to stop what they're doing and clean up and return.

• Center container horizontally and vertically

  - by Joey

  Looking over other question on this site, I used a method of setting all the positions to 0 with auto margins, but this has some unwanted behavior. If you resize the window vertically, the top of the container moves off of the top of the page. It needs to stop when it hits the top. JSFIDDLE: http://jsfiddle.net/jd67ca5y/ HTML: <div id="container"> <p>This is the container.</p> <p>If you resize the JSFiddle window horizontally, you will see that the left edge of the box doesn't move past the left edge of the window. This is correct behaviour.</p> <p>Now if you move the window vertically, the top of this container will disappear off of the top of the window. This is wrong.</p> </div> CSS: #container { margin:auto; height:300px; width:300px; top:0; bottom:0; left:0; right:0; position:absolute; border:1px solid; padding:10px; }

• boost thread pool

  - by Dtag

  I need a threadpool for my application, and I'd like to rely on standard (C++11 or boost) stuff as much as possible. I realize there is an unofficial(!) boost thread pool class, which basically solves what I need, however I'd rather avoid it because it is not in the boost library itself -- why is it still not in the core library after so many years? In some posts on this page and elsewhere, people suggested using boost::asio to achieve a threadpool like behavior. At first sight, that looked like what I wanted to do, however I found out that all implementations I have seen have no means to join on the currently active tasks, which makes it useless for my application. To perform a join, they send stop signal to all the threads and subsequently join them. However, that completely nullifies the advantage of threadpools in my use case, because that makes new tasks require the creation of a new thread. What I want to do is: ThreadPool pool(4); for (...) { for (int i=0;i<something;i++) pool.pushTask(...); pool.join(); // do something with the results } Can anyone suggest a solution (except for using the existing unofficial thread pool on sourceforge)? Is there anything in C++11 or core boost that can help me here? Thanks a lot

• How to "upgrade" the database in real world?

  - by Tattat

  My company have develop a web application using php + mysql. The system can display a product's original price and discount price to the user. If you haven't logined, you get the original price, if you loginned , you get the discount price. It is pretty easy to understand. But my company want more features in the system, it want to display different prices base on different user. For example, user A is a golden parnter, he can get 50% off. User B is a silver parnter, only have 30 % off. But this logic is not prepare in the original system, so I need to add some attribute in the database, at least a user type in this example. Is there any recommendation on how to merge current database to my new version of database. Also, all the data should preserver, and the server should works 24/7. (within stop the database) Is it possible to do so? Also , any recommend for future maintaince advice? Thz u.

• Redeploying an ASP.NET site in IIS7 without files in use interfering

  - by fyjham

  Hey, We've got a process currently which causes ASP.NET websites to be redeployed. The code is itself an ASP.NET application. The current method, which has worked for quite a while, is simply to loop over all the files in one folder and copy them over the top of the files in the webroot. The problem that's arisen is that occasionally files end up being in use and hence can't be copied over. This has in the past been intermittent to the point it didn't matter but on some of our higher traffic sites it happens the majority of the time now. I'm wondering if anyone has a workaround or alternative approach to this that I haven't thought of. Currently my ideas are: Simply retry each file until it works. That's going to cause errors for a short time though which isn't really that good. Deploy to a new folder and update IIS's webroot to the new folder. I'm not sure how to do this short of running the application as an administrator and running batch files, which is very untidy. Does anyone know what the best way to do this is, or if it's possible to do #2 without running the publishing application as a user who has admin access (Willing to grant it special privileges, but I'd prefer to stop short of administrator)?

• Once an HTML document has a manifest (cache.manifest), how can you remove it?

  - by Michael F

  It seems that once you have a manifest entry, a la: <html manifest="cache.manifest"> Then that page (the master entry in the cache) will always be cached (at least by Safari) until the user does something to remove the cache, even if you later remove the manifest attribute from the html tag and update the manifest (by changing something within it), forcing the master entry to be reloaded along with everything else. In other words, if you have: index.html (with manifest defined) file1.js (referenced in manifest) file2.js (referenced in manifest) cache.manifest (lists the two js files) -- removing the manifest entry from index.html and modifying the manifest (so it gets expired by the browser and all content reloaded) will not stop this page from behaving as if it's still fully cached. If you view source on index.html you won't see the manifest listed anymore, but the browser will still request only the cache.manifest file, and unless that file's content is changed, no other changes to any files will be shown to the user. It seems like a pretty glaring bug, and it's present on iOS as well as Mac versions of Safari. Has anyone found a way of resetting the page and getting rid of the cache without requiring user intervention?

• How to tell if leaving iOS app entered foreground from fast-app switching or manually?

  - by JPK

  Is there a way to tell if an iOS app enters the foreground from fast-app switching or manually? I need to know by the time applicationWillEnterForeground is called, so some specific code can be executed (or not executed) depending on the condition in which the app entered the foreground. EDIT: It turned out that this was more of a design issue for me. I moved my code to applicationDidBecomeActive. I also added a BOOL property to the appDelegate called fastAppSwitching (probably the wrong name for it). I set this to YES in application:handleOpenURL and application:openURL:sourceApplication:annotation. Then I added the following code to application:didFinishLaunchingWithOptions: if (launchOptions) { self.fastAppSwitching = YES; } else { self.fastAppSwitching = NO; } In applicationDidBecomeActive, I used the following code: if (fastAppSwitching == YES) { self.fastAppSwitching = NO; //stop, don't go any further } else { ... } EDIT2: MaxGabriel makes a good point below: "Just a warning to others taking the solution described here, applicationDidBecomeActive: is called when the user e.g. ignores a phone call or text message, unlike applicationWillEnterForeground". This is actually also true for in-app purchases and Facebook in-app authorization (new in iOS 6). So, with some further testing, this is the current solution: Add a new Bool called passedThroughWillEnterForeground. In applicationWillResignActive: self.passedThroughWillEnterForeground = NO; In applicationDidEnterBackground: self.passedThroughWillEnterForeground = NO; In applicationWillEnterForeground: self.passedThroughWillEnterForeground = YES; In applicationDidBecomeActive: if (passedThroughWillEnterForeground) { //we are NOT returning from 6.0 (in-app) authorization dialog or in-app purchase dialog, etc //do nothing with this BOOL - just reset it self.passedThroughWillEnterForeground = NO; } else { //we ARE returning from 6.0 (in-app) authorization dialog or in-app purchase dialog - IE //This is the same as fast-app switching in our book, so let's keep it simple and use this to set that self.fastAppSwitching = YES; } if (fastAppSwitching == YES) { self.fastAppSwitching = NO; } else { ... } EDIT3: I think we also need a bool to tell if app was launched from terminated.

• How would I go about letting a user add and associate a comma separated list of categories while add

  - by Throlkim

  I've been struggling for quite a while to get this feature working: I want my user to be able to select categories when uploading a photograph, but additionally be able to specify a comma-separated list of categories to create/find and associate with the photograph. I've had this working by using an attr_accessor :new_categories on the photographs model, but having that there without the column existing breaks both Paperclip and Exifr. Obviously, image upload and EXIF data retrieval are pretty important for a photography website, but not being able to add categories while uploading a photograph is a pain in the arse. Methods I've tried so far: Using attr_accessor to add a field for new_categories. Breaks gems. Using an Ajax sub-form to add categories. Formtastic can't handle it. Adding a column for new_categories to the photograph model. It works, but it's horrific. I haven't tried using a nested form, but I'd need to intercept it and stop it from processing it as normal. Here's an example of what I'm trying to accomplish: http://imgur.com/rD0PC.png And the function I use to associate the categories: def process_new_categories unless self.new_categories.nil? for title in self.new_categories.split(",") self.categories << Category.find_or_create_by_title(title.strip.capitalize) end end end Has anyone got any ideas as to how to do this?

• Have ASP page call save function anytime the user tries to navigate away from page

  - by Breander

  What I have is an input page with a bunch of dynamically created textboxes for the user to input data. The textboxes are dynamically created because the number that are needed are not known until the user selects some options on the page. So what I need to have happen is if the user tries to either A) navigate away from the page or B) select different options bringing up new textboxes. Anything the user may have typed into the textboxes needs to automatically be saved to the database. Like they clicked on the save button on the page. This doesn't sound like a vary smart way to do things or even an easy way to do things but this is the requirement I have been given. No message just save to the database. I have looked into things like onbeforepageunload javascript but that mostly tries to stop the user from navigating away I can't call any code behind code from it. Any help is appreciated. Note : The number of the texboxes with data can be any where between 20 and 500. Yes very crazy but not my idea.

• Search and Matching algorithm

  - by Tony

  Hello everyone. I am trying to come up with an algorithm to do the following: I have total 12 cells that I need to fill until program stops. I have 3 rows and each row has 4 columns. As an example, let me illustrate this as in airplane. So you have 3 rows and each row has 4 columns and you have window/aisle seats. Each row will have a window seat, aisle seat, aisle seat and window seat (|WA AW| Just like seat arrangement in airplane). At each iteration (different set of passengers), there would be some number of passengers (between 1 and 12) and I need to seat them closest together possible (Seat together). And I do this for next group (each iteration) until program stops (It will stop when I am done with every group). For example, I have 3 passengers (A,B,and C) and A wants to seat in Window, B wants to seat in Aisle and C wants to seat in Window. Assuming that all the seats (all 12) are available, I could place them like |A# BC| or |CB #A| and mark the seats dirty (so I don’t pick same seats again for next passengers). And I do this for next group (iteration). I am not sure if this right forum, but if somebody can advise me how I should accomplish, I would really appreciate it. Thanks.

• Port scanning using threadpool

  - by thenry

  I am trying to run a small app that scans ports and checks to see if they are open using and practicing with threadpools. The console window will ask a number and scans ports from 1 to X and will display each port whether they are open or closed. My problem is that as it goes through each port, it sometimes stops prematurely. It doesn't stop at just one number either, its pretty random. For example it I specify 200. The console will scroll through each port then stops at 110. Next time I run it, it stops at 80. Code Left out some of the things, assume all variables are declared where they should. First part is in Main. static void Main(string[] args) { string portNum; int convertedNum; Console.WriteLine("Scanning ports 1-X"); portNum = Console.ReadLine(); convertedNum = Convert.ToInt32(portNum); try { for (int i = 1; i <= convertedNum; i++) { ThreadPool.QueueUserWorkItem(scanPort, i); Thread.Sleep(100); } } catch (Exception e) { Console.WriteLine("exception " + e); } } static void scanPort(object o) { TcpClient scanner = new TcpClient(); try { scanner.Connect("127.0.0.1",(int)o); Console.WriteLine("Port {0} open", o); } catch { Console.WriteLine("Port {0} closed",o); } } }

• How to make div follow scrolling smoothly with jQuery?

  - by Martti Laine

  Hello I'm creating a blog layout, which has an sidebar. In sidebar there are sections/boxes, but the last one of these boxes should follow scrolling when none of the other boxes are visible. So, when user scrolls down, he sees a normal sidebar, but when user has went down enough, sidebar ends but the last box starts to follow on the top of the screen. I have seen this a lot on different kind of sites. So hard to explain with my english. I already made it to follow screen smoothly with animate() but couldn't get it like this. Hope you understood. I already tried in Google for almost an hour but couldn't figure out any keywords (due to my bad english). EDIT: My code at the moment: $(window).scroll(function(){ $.each($('.follow-scroll'),function(){ var eloffset = $(this).offset(); var windowpos = $(window).scrollTop(); if(windowpos<eloffset.top) { var finaldestination = 0; } else { var finaldestination = windowpos; } $(this).stop().animate({'top':finaldestination},200); }); });

• Pipelining String in Powershell

  - by ChvyVele

  I'm trying to make a simple PowerShell function to have a Linux-style ssh command. Such as: ssh username@url I'm using plink to do this, and this is the function I have written: function ssh { param($usernameAndServer) $myArray = $usernameAndServer.Split("@") $myArray[0] | C:\plink.exe -ssh $myArray[1] } If entered correctly by the user, $myArray[0] is the username and $myArray[1] is the URL. Thus, it connects to the URL and when you're prompted for a username, the username is streamed in using the pipeline. Everything works perfectly, except the pipeline keeps feeding the username ($myArray[0]) and it is entered as the password over and over. Example: PS C:\Users\Mike> ssh xxxxx@yyyyy login as: xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyy's password: Access denied xxxxx@yyyyy's password: FATAL ERROR: Server sent disconnect message type 2 (protocol error): "Too many authentication failures for xxxxx" Where the username has been substituted with xxxxx and the URL has been substituted with yyyyy. Basically, I need to find out how to stop the script from piping in the username ($myArray[0]) after it has been entered once. Any ideas? I've looked all over the internet for a solution and haven't found anything.

• How to best manage multi-frame MovieClips with classes?

  - by Arms

  After switching to AS3, I've been having a hell of a time figuring out the best way to manage MovieClips that have UI elements spread across multiple frames with a single class. An example that I am working on now is a simple email form. I have a MovieClip with two frames: the 1st frame has the form elements (text inputs, submit button) the 2nd frame has a "thank you" message and a button to go back to the first frame (to send another email) In the library I have linked the MovieClip to a custom class (Emailer). My immediate problem is how do I assign a MouseEvent.CLICK event to the button on the 2nd frame? I should note at this point that I am trying to avoid putting code on the timeline (except for stop() calls). This is how I am 'solving' the problem now: Emailer registers an event listener for a frame change ( addEventListener("frame 2", onFrameChange) ) On the 2nd frame of the MovieClip I am calling dispatchEvent(new Event("frame 2")); (I would prefer to not have this code on the frame, but I don't know what else to do) My two complaints with this method are that, first I have calls to addEventListener spread out across different class methods (I would rather have all UI event listeners registered in one method), and second that I have to dispatch those custom "onFrameChange" events. The second complaint grows exponentially for MovieClips that have more than just 2 frames. My so called solution feels makes me feel dirty and makes my brain hurt. I am looking for any advice on what to do differently. Perhaps there's a design pattern I should be looking at? Should I swallow my pride and write timeline code even though the rest of my application is written in class files (and I abhor the Flash IDE code editor)? I absolutely LOVE the event system, and have no problem coding applications with it, but I feel like I'm stuck thinking in terms of AS2 when working with mutl-frame movieclips and code. Any and all help would be greatly appreciated.

• Error 1009 after gotoAndStop - stage instance never gets added

  - by ELambda

  I've been through the forums for hours (days?) searching on 1009 errors, but I remain stumped on this. It seems very mysterious and I would LOVE some help if you have any ideas. I have a single .swf that is 7 frames long - each frame represents a different "page" and you can switch pages through a menu widget in the top right corner. The menu widget calls gotoAndPlay( "frame" ). Everything works fine except when I switch from one particular frame to another. Then, during initialization of the new frame (setting some visible properties on various items, in actionscript), I get the dreaded 1009 error on a specific stage instance, a dynamic text instance i_word. Here's what I've tried so far: made sure the actionscript for the new frame starts with a stop() statement before starting initialization - no dice tried changing i_word into a movie_clip instead of dynamic text, made sure it was exported for actionscript - no difference. (I also have 2 other dynamic text instances on the same page that don't seem to cause a problem) added an ENTER_FRAME listener when the new frame is loaded, in case the problem was a timing issue. Put in a big if statement checking if i_word and other instances are not null before proceeding to initialization. It never enters the if, because i_word NEVER gets added. I added trace statements for all instances that are null, and it is the only one. If I remove all references to i_word in my actionscript, everything else is not null, and things go forward. The text for i_word even shows up on the screen in that case. tried renaming i_word - no dice tried deleting the layer i_word was on and adding a new layer - no dice It feels like there is a serious Gremlin in my flash file somewhere. Or maybe I'm missing something obvious. Let me know if you have any ideas...I'd be so grateful. Thank you! Elambda
