  • Infopath - Repeating sections

    - by witsEnd
    I have struggled with this for 2 days and posted this question at a couple of other sites but with no luck. I am creating a form as follows. I have an "outer" repeating section in which the user enters a work item id and then selects as many names as he/she wishes from a series of drop down lists. When the user clicks a button (also in this "outer" repeating section), Feedback textboxes are added for each name selected, as well as text boxes with the names selected from the drop down appear above the those provided for feedback. I used the XPathNavigator.Clone() method to create the new feedback textboxes and textboxes that display the user's name that was selected. (The username textbox appears above the respective feedback textbox). This did the trick, but there is a problem. The user should be able to click "Insert item" on the outer repeating section to add another work item wherein he/she may again select as many names as they wish from the series of drop downs, click a button, and have feedback and user name text boxes appear for each name selected from the drop down box associated with the current work item, (i.e, "outer" repeating section). I clicked Insert Item on the "outer" repeating section and selected 2 names from the second series of drop downs, but when I try to clone a node, it is added at the end of the previous repeating section. I don't know how to navigate into (for lack of a better term) subsequent repeating sections. I am using InfoPath 2007 and I am aware that the current() method call is implicit, but this still doesn't work. I'm thinking I need to set up a Rule somewhere, but I am not sure how to do that. Any help would be appreciated.

  • WinForms Load Event / Static Initialization Strangeness

    - by Eric J.
    Background I'm troubleshooting an WinForms 2.0 program that's already been burned to CD for distribution to an internet-challenged target audience. Some users are experiencing a fatal error that I can reproduce locally. Reproducing the Error I get the fatal error when I log into my Vista box using a standard user that I just created, even if I run the program as administrator. I do not get the fatal error when I log in as local administrator. I'm not sure that being administrator is necessarily the trigger (since runas did not help). I have reproduced this half a dozen times under each account with consistent results. The faulty code Base.cs (base class for several user controls, only one of which is shown on first screen) private void BaseWindow_Load(object sender, EventArgs e) { // This message shown once in both cases MessageBox.Show("BaseWindow_Load for " + this.GetType().FullName); SkinManager.ApplySkin(this); } SkinManager.cs private static Skin skin = null; public static void ApplySkin(UserControl applyTo) { if (skin == null) { skin = new Skin(SkinsDirectory, "Default"); } } Skin.cs internal Skin(string skinPath, string skinName) { config = SkinConfig.Load(path); } SkinConfig.cs public static SkinConfig Load(string path) { // This message shown only once running as Admin but twice running as standard user System.Windows.Forms.MessageBox.Show("@1"); // !!! LOCK path HERE !!! } A user control loads on the first form, which triggers a call to SkinManager.ApplySkin, which checks if skin is null and, if so assigns it (without thread synchronization or recursion protection), which ultimately causes a file to be opened. When logged in as local admin, that sequence completes just fine. When logged in as my test standard user, ApplySkin is always called a second time while skin is still null, causing a second attempt to load, causing the file to be locked on the second attempt. The error handling is draconian at this point and the program terminates. The Question While this code can be easily fixed, I would like to understand why the error is happening only in some cases.

  • USE case to Class Diagram - How do I?

    - by 01010011
    Hi, I would like your guidance on how to create classes and their relationships (generalization, association, aggregation and composition) accurately from my USE case diagram (please see below). I am trying to create this class diagram so I can use it to create a simple online PHP application that allows the user to register an account, login and logout, and store, search and retrieve data from a MySQL database. Are my classes correct? Or should I create more classes? And if so, what classes are missing? What relationships should I use when connecting the register, login, logout, search_database and add_to_database to the users? I'm new to design patterns and UML class diagrams but from my understanding, the association relationship relates one object with another object; the aggregation relationship is a special kind of association that allows "a part" to belong to more than one "whole" (e.g. a credit card and its PIN - the PIN class can also be used in a debit card class); and a composition relationship is a special form of aggregation that allows each part to belong to only one whole at a time. I feel like I have left out some classes or something because I just can't seem to find the relationships from my understanding of relationships. Any assistance will be really appreciated. Thanks in advance. USE CASE DIAGRAM CLASS DIAGRAM

  • Exporting non-public type through public API

    - by feelgood
    What if I have few factory methods returning non-public type and pairing set of methods which gives variables of this non-public type? This results with titled warning message in NetBeans. In result public API will contain only two pairing sets of methods. The reason is to make my type hierarchy sealed (like seald classes in Scala) and allow users only instantiate these types through factory methods. So we get DSL in some sense. For example, Schedule class represented by calendar fields' contraints. There are some types of contraints - Range, Singleton, List, FullSet - with NumberSet interface as a root. We don't want to expose these types and how Schedule interact with them. We just want the specification from the user. So we make NumberSet package-private. In class Schedule we create few factory-methods for constraints: NumberSet singleton(int value); NumberSet range(int form, int to); NumberSet list(NumberSet ... components); and some methods for creating Schedule object: Schedule everyHour(NumberSet minutes); Schedule everyDay(NumberSet minutes, NumberSet hours); User can only use them in the manner: Schedule s = Schedule.everyDay( singleton(0), list(range(10-15), singleton(8)) ); Is it bad idea?

  • Versioning friendly, extendible binary file format

    - by Bas Bossink
    In the project I'm currently working on there is a need to save a sizable data structure to disk (edit: think dozens of MB's). Being an optimist, I thought that there must be a standard solution for such a problem; however, up to now I haven't found a solution that satisfies the following requirements: .NET 2.0 support, preferably with a FOSS implementation Version friendly (this should be interpreted as: reading an old version of the format should be relatively simple if the changes in the underlying data structure are simple, say adding/dropping fields) Ability to do some form of random access where part of the data can be extended after initial creation (think of this as extending intermediate results) Space and time efficient (XML has been excluded as option given this requirement) Options considered so far: Protocol Buffers: was turned down by verdict of the documentation about Large Data Sets - since this comment suggested adding another layer on top, this would call for additional complexity which I wish to have handled by the file format itself. HDF5,EXI: do not seem to have .net implementations SQLite/SQL Server Compact edition: the data structure at hand would result in a pretty complex table structure that seems too heavyweight for the intended use BSON: does not appear to support requirement 3. Fast Infoset: only seems to have paid .NET implementations. Any recommendations or pointers are greatly appreciated. Furthermore if you believe any of the information above is not true, please provide pointers/examples to prove me wrong.

  • Majordomo/Mailman - Yahoo/Google Groups

    - by tom smith
    Hi. Not an app question, but thought that I might ask here anyway! The responses might help someone. I've got an app where we're going to be dealing with 5000-10000 people in a group/pool. Periodically, different subsets of people will break off in their own group. I'm looking for thoughts on how to manage/approach this situation. (For now, all of this is being managed on a few servers in the garage, with dynamic IP) I've looked into the Yahoo/google groups, and they seem to be reasonable. The primary issue that I see with this approach, is that I don't have a good way of quickly/easily alowing a subset of the group to form their own group for a given project. This kind of function is critical. The upside to this though, I wouldn't have to really set anything up. And the hosted groups could send emails to the user all day along, without running into cap/bandwidth limits The other approach is a managed list, like mailman/majordomo. This approach appears to be more flexible, and looks like ti could be modified to handle the quick creation of lists, allowing users to quickly be assigned to different lists on the fly.. The downside, I'd have to run my own Mailman/Majordomo instance, as well as the associated mail server. Or I could look at possibly using one of the hosted service.. But this is for a project on the cheap, so we're really trying to keep costs down. Thoughts/Comments/Pointers would be greatly appreciated. Thanks in advance -tom

  • FOR BOUNTY: "QFontEngine(Win) GetTextMetrics failed ()" error on 64-bit Windows

    - by David Murdoch
    I'll add a large bounty to this when Stack Overflow lets me. I'm using wkhtmltopdf to convert HTML web pages to PDFs. This works perfectly on my 32-bit dev server [unfortunately, I can't ship my machine :-p ]. However, when I deploy to the web application's 64-bit server the following errors are displayed: C:\>wkhtmltopdf http://www.google.com google.pdf Loading pages (1/5) QFontEngine::loadEngine: GetTextMetrics failed () ] 10% QFontEngineWin: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () QFontEngine::loadEngine: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () QFontEngine::loadEngine: GetTextMetrics failed () ] 36% QFontEngineWin: GetTextMetrics failed () QFontEngineWin: GetTextMetrics failed () // ...etc.... and the PDF is created and saved... just WITHOUT text. All form-fields, images, borders, tables, divs, spans, ps, etc are rendered accurately...just void of any text at all. Server information: Windows edition: Windows Server Standard Service Pack 2 Processor: Intel Xeon E5410 @ 2.33GHz 2.33 GHz Memory: 8.00 GB System type: 64-bit Operating System Can anyone give me a clue as to what is happening and how I can fix this? Also, I wasn't sure what to tag/title this question with...so if you can think of better tags/title comment them or edit the question. :-)

  • Is there something like a "long running offline transaction" for NHibernate or any other ORM?

    - by Vilx-
    In essence this is a followup of this question. I'm beginning to feel that I should give up the whole idea, but I'll give it one more shot. What I want is pretty much like a DB transaction. It should track my changes to the DB and then in the end allow me to either commit or rollback them. If I insert an object, I should get it back in my next (appropriate) SELECT query. If I delete it, future SELECT queries should not return it. Etc. But there is one catch - this transaction would be very long running. It would start when the user opened a form (I'm talking about Windows Forms here), and the commit/rollback would be when the user closed it(with OK/Cancel). So it could take anywhere between seconds and days. This requirement rules out a standard DB transaction because that would lock the tables/rows it touched, and other users wouldn't be able to use the system. Also the transaction should not commit ANY changes to the DB until it was really committed. So if one user makes some changes, others don't see them until OK button is hit. This prevents errors in case the computer crashes or is disconnected from the network. I'm quite OK if the solution puts constraints on my model (I'm using MSSQL 2008, btw). I can design the DB/code any way I like. I'm also fine with the idea that a commit could fail because someone already modified one of the objects my transaction touched. Is there anything like this? I looked at NHibernate.Burrow, but I'm not sure that that's the thing I want. Added: It's the very beginning of the project so I'm not tied to NHibernate. I started out with it but I can still change easily.

  • How do I manage application configuration in ASP.NET?

    - by GlennS
    I am having difficulty with managing configuration of an ASP.Net application to deploy for different clients. The sheer volume of different settings which need twiddling takes up large amounts of time, and the current configuration methods are too complicated to enable us to push this responsibility out to support partners. Any suggestions for better methods to handle this or good sources of information to research? How we do things at present: Various xml configuration files which are referenced in Web.Config, for example an AppSettings.xml. Configurations for specific sites are kept in duplicate configuration files. Text files containing lists of data specific to the site In some cases, manual one-off changes to the database C# configuration for Windsor IOC. The specific issues we are having: Different sites with different features enabled, different external services we have to talk to and different business rules. Different deployment types (live, test, training) Configuration keys change across versions (get added, remove), meaning we have to update all the duplicate files We still need to be able to alter keys while the application is running Our current thoughts on how we might approach this are: Move the configuration into dynamically compiled code (possibly Boo, Binsor or JavaScript) Have some form of diffing/merging configuration: combine a default config with a live/test/training config and a site-specific config

  • Java NIO (Netty): How does Encryption or GZIPping work in theory (with filters)

    - by Tom
    Hello Experts, i would be very thankfull if you can explain to me, how in theory the "Interceptor/Filter" Pattern in ByteStreams (over Sockets/Channels) work (in Asynchronous IO with netty) in regard to encryption or compression of data. Given I have a Filter that does GZIPPING. How is this internally implemented? Does the Filter "collect" so many bytes form the channel, that this is a usefull number of bytes that can then be en/decoded? What is in general the minimal "blocksize(data to encode/decode in a chunk)" of socket based gzipping? Does this "blocksize" have to be negotiated in advance between server and client? What happens if the client does not send enough data to "fill" the blocksize (due to a network conquestion) but does not close the connection. Does this mean the other side will simply wait until it gets enough bytes to decode or until a timeout occoures...How is the Filter pattern the applied? The compression filter will de/compress the blocksize of bytes and then store them again in the same buffer would (in the case of netty) i normally be using the ChannelHanlderContext to pass the de/encoded data to the next filter?... Any explanations/links/tutorials (for beginners;-) will be very much appreciated to help me understand how for example encryption/compressing are implemented in socket based communication with filters/interceptor pattern. thank you very much tom

  • cakephp: Custom Authentication Object authenticate not called

    - by Kristoffer Darj
    The method authenticate in a Custom Authentication Object is never called. Is this a glicth or am I missing something? I don't get anything in the log, I'm just redirected to users/login (or the one I specified) CakeVersion: 2.4.1 <?php //My custom Auth Class //Path: app/Controller/Component/Auth/HashAuthenticate.php App::uses('BaseAuthenticate', 'Controller/Component/Auth'); class HashAuthenticate extends BaseAuthenticate { public function authenticate(CakeRequest $request, CakeResponse $response) { //Seems to not be called CakeLog::write('authenticate'); debug($this); die('gaah'); } } If I add the method getUser() (or unauthenticated() ), those gets called however so at least I know that cake finds the class and so on. It just skips the authenticate-method. The AppController looks like this class AppController extends Controller { public $helpers = array('Html', 'Form', 'Session'); public $components = array('Auth' => array( 'authenticate' => array('Hash'), 'authorize' => array('Controller'), ) ); } I found a similar question here: CakePHP 2.x custom "Authentication adapter &quot;LdapAuthorize&quot; was not found but there the issue was typos.

  • SmtpClient.SendAsync - How to ensure my application doesn't finish before callback?

    - by James
    Hi, I need to send emails asychronously through a console application. I need to do some DB updates on the callback but my application is exiting before the callback code gets run! How can I stop this from happening in a nice manner rather than simply guessing how long to wait before exiting. I would imagine the Async calls get placed in some form of thread? Is it possible to check if any are waiting to be called? Sample Code private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e) { // Get the unique identifier for this asynchronous operation. String token = (string) e.UserState; if (e.Cancelled) { Console.WriteLine("[{0}] Send canceled.", token); } if (e.Error != null) { Console.WriteLine("[{0}] {1}", token, e.Error.ToString()); } else { // update DB Console.WriteLine("Message sent."); } } public static void Main(string[] args) { var users = Repository.GetUsers(); SmtpClient client = new SmtpClient("Host"); client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback); MailAddress from = new MailAddress("[email protected]", "System", Encoding.UTF8); foreach (var user in users) { MailAddress to = new MailAddress(user.Email); MailMessage message = new MailMessage(from, to); message.Body = "This is a test"; message.BodyEncoding = System.Text.Encoding.UTF8; message.Subject = "test message 1" + someArrows; message.SubjectEncoding = System.Text.Encoding.UTF8; string userState = String.Format("Message for user id {0}", user.ID); client.SendAsync(message, userState); message.Dispose(); } // need to wait here until I have received a callback for each message // otherwise the application will exit }

  • ASP.NET MVC Ajax.BeginForm eats params of submit button clicked. Looks like bug.

    - by RonnBlack
    If you are using Ajax.BeginForm() with multiple submit buttons similar to this: // View.aspx <% using (Ajax.BeginForm("Action", "Controller", new AjaxOptions { UpdateTargetId = "MyControl", })) { %> <span id="MyControl"> <% Html.RenderPartial("MyControl"); %> </span> <% } %> //MyControl.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <input name="prev" type="submit" value="prev" /> <input name="next" type="submit" value="next" /> //... Everything is submitted to the controller fine but the params for the submit button that was clicked are absent from the Request. In otherwords Request["next"] and Request["prev"] are always null. I looked in to the JavaScript in Microsoft.MvcAjax.js and it looks like the function Sys_Mvc_MvcHelpers$_serializeForm completely skips over the inputs that are of type 'submit'. This doesn't seem logical at all. How else can you find out what button has been clicked? It looks like a bug to me. Is there any logical reason to skip these form parameters?

  • How can I make an AdvancedDataGrid re-display its labels when the results of the labelFunction chang

    - by Chris R
    I have an AdvancedDataGrid with a custom label function whose value can change based on other form status (specifically, there's a drop down to choose the time display format for some columns). Right now, I have this labelFunction: internal function formatColumnTime(item: Object, column: AdvancedDataGridColumn): String { var seconds: Number = item[column.dataField]; return timeFormat.selectedItem.labelFunction(seconds); } internal function formatTimeAsInterval(time: Number): String { if (isNaN(time)) return ""; var integerTime: int = Math.round(time); var seconds: int = integerTime % 60; integerTime = integerTime / 60; var minutes: int = integerTime % 60; var hours: int = integerTime / 60; return printf("%02d:%02d:%02d", hours, minutes, seconds); } internal function formatTimeAsFractions(time: Number): String { if (isNaN(time)) return ""; var hours: Number = time / 3600.0; return new String(Math.round(hours * 100) / 100); } ... and the timeFormat object is a combo box with items whose labelFunction attributes are formatTimeAsFractions and formatTimeAsInterval. The columns that have time formats have formatColumnTime as their labelFunction value, because extracting the seconds in that function and passing it in to the formatters made for a more testable app (IMHO). So, when the timeFormat.selectedItem value changes, I want to force my grid to re-calculate the labels of these colums. What method must I call on it? invalidateProperties() didn't work, so that's out.

  • UCMA 3.0 How to build a list of recipients and then broadcast an IM call to those recipients

    - by ficuscr
    I am developing an application using UCMA 3.0 that will run as a service and send out periodic 'broadcasts' in the form of Instant Message calls. I have been using the book "Professional Unified Communications Development with Microsoft Lync Server 2010" and have everything provisioned fine and am able to establish an application endpoint. I am stuck on two aspects though. 1) How to get a list of all users of Lync? Everything the UCMA can do is centered on a single user. For example it allows me to retrieve all contacts/groups present on a given users 'contact list' but does not provide any means to query for a list of available contacts that could be added to one of those contact lists. On the MSDN forum I found this post which leads me to think my best bet is simply to query AD directly. 2) What is the best way to actually send a broadcast style IM? My working premise is to attempt something like what I've found in this code example (specifically the public void SendIM() method). So, get a list of recipients from AD, (looping on each on to check current presence?), and then use Automation to make the IM call for each recipient in the collection. Does that make sense? Do I need to check presence of the recipient or do I just optimistically make the IM calls irregardless of their current presence status? Can anyone point me to some working code demonstrating sending an IM broadcast? You would think this is probably one of the most common use cases however the SDK samples do not cover it. Thanks in advance.

  • IdHTTP XML, getting xml, help please

    Already some day I can not solve the problem. Help than you can. I'm using Delphi 2010, and I can not get through IdHTTP XML document from the site.

  • Drag-n-Drop on contentEditable elements

    - by Raybiez
    There are numerous WYSIWYG editors available on the internet, but I'm yet to find one that implements some form of drag-n-drop implementation. It is easy to create one's own editor, but I want to the user to be able to drag elements (ie. tokens) from outside the editable area and have them drop it at a location of their choice inside the editable area. It is easy to inject html at a specific location of an editable element, but how do one determine where the caret should be when the user is dragging a DIV over some element in the editable area. To better illustrate what I'm trying to explain, see the following scenario. The editable area (either an IFRAME in edit mode or a DIV with its contentEditable attribute set to true) already contains the following text: "Dear , please take note of ...." The user now drags an element representing some token from a list of elements, over the editable area, moving the cursor over the text until the caret appear just before the comma (,) in the text as shown above. When the user releases the mouse button at that location, HTML will be injected which could result in something like this: "Dear {UserFirstName}, please take note of ...". I do not know if anyone has ever done anything similar to this, or at least know of how one would go about doing this using JavaScript. Any help will be greatly appreciated.

  • UINavigationBar is getting buttons from another view

    - by Rafael Oliveira
    I have three Views, Splash, Login and List. From Splash I just wait and then Push Login View, with the Navigation Bar hidden. In Login I Show the NavigationBar, hide the BackButton1 and add a new RightButton1, then I check if Settings.bundle "login" and "pass" are set. If so, I push List View. Otherwise I stay in the Login view waiting for the user to fill the form and press a button. In List View I add a new RightButton2 and a new BackButton2. The problem is that if Settings.bundle data is not null, and in Login View I quickly push List View the RightButton1 appears in List View, or no buttons appear at all, or only BackButton2 doesn't appear... The most strange thing of all is that everything was OK and all of sudden it started to get messy. Login View: // Making the Navigation Bar Visible [self.navigationController setNavigationBarHidden:NO animated:NO]; // Hiding the Back Button in THIS view (Login) [self.navigationItem setHidesBackButton:YES]; // Inserting the Logout Button for the Next View (List) UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Logout" style:UIBarButtonItemStylePlain target:nil action:nil]; self.navigationItem.backBarButtonItem = backButton; [backButton release]; UIBarButtonItem* newAccountButton = [[UIBarButtonItem alloc] initWithTitle:@"New Account" style:UIBarButtonItemStylePlain target:self action:@selector(newAccountButtonPressed)]; self.navigationItem.rightBarButtonItem = newAccountButton; [newAccountButton release]; List View // Making the Navigation Bar Visible [self.navigationController setNavigationBarHidden:NO animated:NO]; UIBarButtonItem* aboutButton = [[UIBarButtonItem alloc] initWithTitle:@"About" style:UIBarButtonItemStylePlain target:self action:@selector(aboutButtonPressed)]; self.navigationItem.rightBarButtonItem = aboutButton; [aboutButton release]; Any ideas ?

  • Deriving an HTMLElement Object from jQuery Object

    - by Jasconius
    I'm doing a fairly exhaustive series of DOM manipulations where a few elements (specifically form elements) have some events. I am dynamically creating (actually cloning from a source element) several boxes and assigning a change() event to them. The change event executes, and within the context of the event, "this" is the HTML Element Object. What I need to do at this point however is determine a contact for this HTML Element Object. I have these objects stored already as jQuery entities in assorted arrays, but obviously [HTMLElement Object] != [Object Object] And the trick is that I cannot cast $(this) and make a valid comparison since that would create a new object and the pointer would be different. So... I've been banging my head against this for a while. In the past I've been able to circumvent this problem by doing an innerHTML comparison, but in this case the objects I am comparing are 100% identical, just there's lots of them. Therefore I need a solid comparison. This would be easy if I could somehow derive the HTMLElement object from my originating jQuery object. Thoughts, other ideas? Help. :(

  • how to create wizard forms in ruby on rails

    - by Branden Silva
    I'm trying to understand the best options for pulling off a wizard form in ruby on rails. Ideally I'd like to have it so the application signup has a back and next button that allows the user to submit data in steps. So in step 1 they could fill out contact info. Once they are done they could click next and be on step 2 to fill out payment info, etc. If they make a mistake, they can click back and correct it. Some steps will be required, while others will not, but you do have to make it to the last step to submit the data to the database to sign up. They then need the ability to go back and fill out the past steps in the same fashion after completion. (example: perhaps if they clicked on a profile link they could recomplete the steps in the same fashion because they didn't want to complete all the steps right away. Maybe by being given a skip button before they completed the steps to sign up?). I also need validation to happen on what steps have been completed preventing them from moving onto the next step until corrected or completed. Option 1) I've noticed that ajax has been recommended as an option in other questions on stackoverflow. The only problem I have with it is that the user would not be able to sign up if javascript was disabled. Ideally I'd like to have it be native to ruby on rails but I'm willing to work with whatever is necessary to get it to work.

  • Upload image from J2ME client to a Servlet

    - by Akash
    I want to send an image from a J2ME client to a Servlet. I am able to get a byte array of the image and send it using HTTP POST. conn = (HttpConnection) Connector.open(url, Connector.READ_WRITE, true); conn.setRequestMethod(HttpConnection.POST); conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); os.write(bytes, 0, bytes.length); // bytes = byte array of image This is the Servlet code: String line; BufferedReader r1 = new BufferedReader(new InputStreamReader(in)); while ((line = r1.readLine()) != null) { System.out.println("line=" + line); buf.append(line); } String s = buf.toString(); byte[] img_byte = s.getBytes(); But the problem I found is, when I send bytes from the J2ME client, some bytes are lost. Their values are 0A and 0D hex. Exactly, the Carriage Return and Line Feed. Thus, either POST method or readLine() are not able to accept 0A and 0D values. Any one have any idea how to do this, or how to use any another method?

  • StackOverFlowException - but oviously NO recursion/endless loop

    - by user567706
    Hi there, I'm now blocked by this problem the entire day, read thousands of google results, but nothing seems to reflect my problem or even come near to it... i hope any of you has a push into the right direction for me. I wrote a client-server-application (so more like 2 applications) - the client collects data about his system, as well as a screenshot, serializes all this into a XML stream (the picture as a byte[]-array]) and sends this to the server in regular intervals. The server receives the stream (via tcp), deserializes the xml to an information-object and shows the information on a windows form. This process is running stable for about 20-25 minutes at a submission interval of 3 seconds. When observing the memory usage there's nothing significant to see, also kinda stable. But after these 20-25 mins the server throws a StackOverflowException at the point where it deserializes the tcp-stream, especially when setting the Image property from the byte[]-array. I thoroughly searched for recursive or endless loops, and regarding the fact that it occurs after thousands of sucessfull intervals, i could hardly imagine that. public byte[] ImageBase { get { MemoryStream ms = new MemoryStream(); _screen.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); return ms.GetBuffer(); } set { if (_screen != null) _screen.Dispose(); //preventing well-known image memory leak MemoryStream ms = new MemoryStream(value); try { _screen = Image.FromStream(ms); //<< EXCEPTION THROWING HERE } catch (StackOverflowException ex) //thx to new CLR management this wont work anymore -.- { Console.WriteLine(ex.Message + Environment.NewLine + ex.StackTrace); } ms.Dispose(); ms = null; } } I hope that more code would be unnecessary, or it could get very complex... Please help, i have no clue at all anymore thx Chris

  • jQuery: loading reCaptcha into a div via ajax

    - by abdullah kahraman
    Hello, I want to create a form that has a div with id "captcha". When the user enters a wrong password, following code is generated in "login.php" $myCaptcha=recaptcha_get_html($publickey, $error); $xml="<captcha><![CDATA[".$myCaptcha ."]]></captcha>"; echo $xml; recaptcha_get_html($publickey, $error); generates this: <script type="text/javascript" src="http://www.google.com/recaptcha/api/challenge?k=xxxx"></script> <noscript> <iframe src="http://www.google.com/recaptcha/api/noscript?k=xxxx" height="300" width="500" frameborder="0"></iframe><br/> <textarea name="recaptcha_challenge_field" rows="3" cols="40"></textarea> <input type="hidden" name="recaptcha_response_field" value="manual_challenge"/> </noscript> I want to get this code with $.post() and insert it into div "captcha". Doing something like this: $.post("login.php", {requestCaptcha:"yes"}, function(returned){ $("#captcha").html($(returned).text(),"xml"); }); In IE, it does nothing. In Chrome, it clears up whole page and there is only the called reCaptcha script working like a charm. Any ideas?

  • Haskell Linear Algebra Matrix Library for Arbitrary Element Types

    - by Johannes Weiß
    I'm looking for a Haskell linear algebra library that has the following features: Matrix multiplication Matrix addition Matrix transposition Rank calculation Matrix inversion is a plus and has the following properties: arbitrary element (scalar) types (in particular element types that are not Storable instances). My elements are an instance of Num, additionally the multiplicative inverse can be calculated. The elements mathematically form a finite field (??2256). That should be enough to implement the features mentioned above. arbitrary matrix sizes (I'll probably need something like 100x100, but the matrix sizes will depend on the user's input so it should not be limited by anything else but the memory or the computational power available) as fast as possible, but I'm aware that a library for arbitrary elements will probably not perform like a C/Fortran library that does the work (interfaced via FFI) because of the indirection of arbitrary (non Int, Double or similar) types. At least one pointer gets dereferenced when an element is touched (written in Haskell, this is not a real requirement for me, but since my elements are no Storable instances the library has to be written in Haskell) I already tried very hard and evaluated everything that looked promising (most of the libraries on Hackage directly state that they wont work for me). In particular I wrote test code using: hmatrix, assumes Storable elements Vec, but the documentation states: Low Dimension : Although the dimensionality is limited only by what GHC will handle, the library is meant for 2,3 and 4 dimensions. For general linear algebra, check out the excellent hmatrix library and blas bindings I looked into the code and the documentation of many more libraries but nothing seems to suit my needs :-(. Update Since there seems to be nothing, I started a project on GitHub which aims to develop such a library. The current state is very minimalistic, not optimized for speed at all and only the most basic functions have tests and therefore should work. But should you be interested in using or helping out developing it: Contact me (you'll find my mail address on my web site) or send pull requests.
