• Sharing session variables from http and https versio

  - by tangurena

  I am trying to fix an ASP.NET site that a friend had botched converting from older technologies. To the user, the site appears to have public and secured sections. Behind the scenes, the public and private sites are separate web applications with separate app pools. The difficulty arises because it appears that the applications share the same session IDs (when going from the public to the secured pages, the session ID remains the same), yet none of the (InProc) session variables are getting passed from the public site to the private one. Basically, the workflow consists of the user checking a checkbox ("I agree" type of stuff) on the public site (let's call that page http://www.boring.gov/iAgree.aspx), then logging in on the secured site (let's call that page https://www.boring.gov/login.aspx). The commandments from the parent agency in DC are that the user may not bookmark the login page, the user has to click "I agree" every time they log in, and that the "I agree" stuff has to be on a separate page. What am I missing? How would you do it? Notes: 1 - This is getting hosted on a single Windows 2003 server. 2 - Yes, it is a government agency. 3 - I would have done things very differently if I was doing the conversion, but I wasn't brought in until the poop hit the fan, and it is too late to redo things. 4 - Two previous SO threads that appear to be related, yet don't apply are this and that

• Qt Socket blocking functions required to run in QThread where created. Any way past this?

  - by Alexander Kondratskiy

  The title is very cryptic, so here goes! I am writing a client that behaves in a very synchronous manner. Due to the design of the protocol and the server, everything has to happen sequentially (send request, wait for reply, service reply etc.), so I am using blocking sockets. Here is where Qt comes in. In my application I have a GUI thread, a command processing thread and a scripting engine thread. I create the QTcpSocket in the command processing thread, as part of my Client class. The Client class has various methods that boil down to writing to the socket, reading back a specific number of bytes, and returning a result. The problem comes when I try to directly call Client methods from the scripting engine thread. The Qt sockets randomly time out and when using a debug build of Qt, I get these warnings: QSocketNotifier: socket notifiers cannot be enabled from another thread QSocketNotifier: socket notifiers cannot be disabled from another thread Anytime I call these methods from the command processing thread (where Client was created), I do not get these problems. To simply phrase the situation: Calling blocking functions of QAbstractSocket, like waitForReadyRead(), from a thread other than the one where the socket was created (dynamically allocated), causes random behaviour and debug asserts/warnings. Anyone else experienced this? Ways around it? Thanks in advance.

• Save a form in an XML file using Ajax and JSP

  - by novellino

  Hello, I want to create a simple form with a name and an email and save these data in an XML file. So far I found that using Ajax with jQuery is quite easy. So I used the usual code: //dataString have the values taken from the form var dataString = 'name='+ name + '&email=' + email; $.ajax({ type: "POST", url: "users.xml", data: dataString, dataType: "xml", success: function() { .... } }); If I understood well, in the url I should add the name of the XML file that will be created. When the user clicks a button I call the function with the Ajax request, and then I should call somewhere a function for generating the xml. I am using also two beans. One is for setting the elements of the user and the other is for saving the data in the XML. I am using the XStream library for the xml although I don't know if is the best solution. The problem now it that I can not connect all these together in order to save the data in the XML. Does anyone know what should I do? Thanks a lot!

• POSTing JSON data to WCF REST

  - by Randall Sexton

  I'm trying to send data from a client application using jQuery to a REST WCF service based on the WCF REST starter kit. Here's what I have so far. Service Definition: [WebHelp(Comment = "Save PropertyValues to the database")] [WebInvoke(Method = "POST", UriTemplate = "PropertyValues_Save", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] [OperationContract] public bool PropertyValues_Save(Guid assetId, Dictionary<Guid, string> newValues) { ... } Call from the client: $.ajax({ url:SVC_PROPERTYVALUES_SAVE, type: "POST", contentType: "application/json; charset=utf-8", data: jsonData, dataType: "json", error: function(XMLHttpRequest, textStatus, errorThrown) { alert(textStatus + ' ' + errorThrown); }, success: function(data) { if (data) { alert('Values saved'); $("#confirmSubmit").dialog('close'); } else { alert('Values failed to save'); $("#confirmSubmit").dialog('close'); } } }); Example of the JSON being passed: { "assetId": "d70714c3-e403-4cc5-b8a9-9713d05b2ee0", "newValues": [ { "key": "bd01aa88-b48d-47c7-8d3f-eadf47a46680", "value": "0e9fdf34-2d12-4639-8d70-19b88e753ab1" }, { "key": "06e8eda2-a004-450e-90ab-64df357013cf", "value": "1d490aec-f40e-47d5-865c-07fe9624f955" } ] } I'm using Windows Authentication on the virtual directory. When I call operations that are GETs, everything is fine. This code is prompting the browser to log in. When I enter my credentials, I simply get an alert in my browser which says "error undefined". Even if you can't help my specific error, do you see anything that looks wrong from glancing? I've been beating my head on this nearly all day. Thanks in advance.

• Spring bean's DESTROY-METHOD attribute and web-application "prototype"d bean

  - by EugeneP

  Can get work the attribute "destroy-method". First, even if I type non-existing method name into "destroy-method" attribute, Spring initialization completes fine (already strange!). Next, when a bean has a "prototype" scope, then I suppose it must be destroyed before the application is closed. That not happens, it is simply never called in my case. Though, after extracting this bean I can call this method explicitly and it does its job. Could you explain why this method is never called in my Spring 2.5 case? p.s. The method exists, it is public and has no arguments. It seems to be a more difficult task then I thought. The problem is that this destroy method is called whenever the context is closed, and this is a rare case. My question is this: I have a web app. I have a "prototype"-scoped bean. What I need is when the current session is closed, this destroy method was automatically called by Spring. I can do it by hand, but is there any solution how to make Spring do this job? It destroys the bean after the session is destroyed, it might be possible for Spring to call a method on that bean before destroying it?

• Dynamically created controls and the ASP.NET page lifecycle

  - by Dirk

  I'm working on an ASP.NET project in which the vast majority of the forms are generated dynamically at run time (form definitions are stored in a DB for customizability). Therefore, I have to dynamically create and add my controls to the Page every time OnLoad fires, regardless of IsPostBack. This has been working just fine and .NET takes care of managing ViewState for these controls. protected override void OnLoad(EventArgs e) { base.OnLoad(e); RenderDynamicControls() } private void RenderDynamicControls(){ //1. call service layer to retrieve form definition //2. create and add controls to page container } I have a new requirement in which if a user clicks on a given button (this button is created at design time) the page should be re-rendered in a slightly different way. So in addition to the code that executes in OnLoad (i.e. RenderDynamicControls()), I have this code: protected void MyButton_Click(object sender, EventArgs e) { RenderDynamicControlsALittleDifferently() } private void RenderDynamicControlsALittleDifferently() (){ //1. clear all controls from the page container added in RenderDynamicControls() //2. call service layer to retrieve form definition //3. create and add controls to page container } My question is, is this really the only way to accomplish what I'm after? It seems beyond hacky to effectively render the form twice simply to respond to a button click. I gather from my research that this is simply how the page-lifecycle works in ASP.NET: Namely, that OnLoad must fire on every Postback before child events are invoked. Still, it's worthwhile to check with the SO community before having to drink the kool-aid. On a related note, once I get this feature completed, I'm planning on throwing an UpdatePanel on the page to perform the page updates via Ajax. Any code/advice that make that transition easier would be much appreciated. Thanks

• Float a div in top right corner without overlapping sibling header

  - by Maxime R.

  Having a div and a h1 inside a section, how do i float the div in the top right corner without overlapping the text of the header ? The HTML code is the following: <section> <h1>some long long long long header, a whole line, 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6</h1> <div><button>button</button></div> </section> I tried an absolute position relative to the parent but the text is overlapped, http://jsfiddle.net/FnpS8/2/ Using this CSS code: section { position: relative; } h1 { display: inline; } div { position: absolute; top: 0; right: 0; } I tried floating the div to the right but it doesn't remain in the top right corner, http://jsfiddle.net/P6xCw/2/ Using this CSS code: h1 { display: inline; } div { float: right; } ? I know there is a lot of similar questions but I couldn't find one solving this case.

• Apache CXF REST Services w/ Spring AOP

  - by jconlin

  I'm trying to get Apache CXF JAX-RS services working with Spring AOP. I've created a simple logging class: public class AOPLogger{ public void logBefore(){ System.out.println("Logging Before!"); } } My Spring configuration (beans.xml): <aop:config> <aop:aspect id="aopLogger" ref="test.aop.AOPLogger"> <aop:before method="logBefore" pointcut="execution(* test.rest.RestService(..))"/> </aop:aspect> </aop:config> <bean id="aopLogger" class="test.aop.AOPLogger"/> I always get an NPE in RestService when a call is made to a Method getServletRequest(), which has: return messageContext.getHttpServletRequest(); If I remove the aop configuration or comment it out from my beans.xml, everything works fine. All of my actual Rest services extend test.rest.RestService (which is a class) and call getServletRequest(). I'm just trying to just get AOP up and running based off of the example in the CXF JAX-RS documentation. Does anyone have any idea what I'm doing wrong? Thanks!

• Jquery autocomplete webservices - what am i doing wrong??

• Visual Studio: How to attach a debugger dynamically to a specific process

  - by Jeff Cyr

  I am building an internal dev tool to manage different processes commonly used in our development environment. The tool show the list the monitored processes, indicate their running state and allow to start or stop each process. I'd like to add the functionality of attaching a debugger to a monitored process from my tool instead of going in 'Debug-Attach to process' in visual studio and finding the process. My goal is to have something like Debugger.Launch() that would show a list of the available visual studio. I can't use Debugger.Launch() because it lauches the debugger on the process that make the call. I would need something like Debugger.Launch(processId). Does anyone know how to acheive this functionality? A solution could be to implement a command in each monitored process to call Debugger.Launch() when the command is received from the monitoring tool, but I would prefer something that does not require to modify the code of the monitored processes. Side question: When using Debugger.Launch(), instances of Visual Studio that already have a debugger attached are not listed. Visual Studio is not limited to one attached debugger, you can attach on multiple process when using 'Debug - Attach to process'. Anyone know how to bypass this limitation when using Debugger.Launch() or an alternative?

• Does Ctypes Structures and POINTERS automatically free the memory when the Python object is deleted?

  - by jsbueno

  When using Python CTypes there are the Structures, that allow you to clone c-structures on the Python side, and the POINTERS objects that create a sofisticated Python Object from a memory address value and can be used to pass objects by reference back and forth C code. What I could not find on the documentation or elsewhere is what happens when a Python object containing a Structure class that was de-referenced from a returning pointer from C Code (that is - the C function alocated memory for the structure) is itself deleted. Is the memory for the original C structure freed? If not how to do it? Furthermore -- what if the Structure contains Pointers itself, to other data that was also allocated by the C function? Does the deletion of the Structure object frees the Pointers onits members? (I doubt so) Else - -how to do it? Trying to call the system "free" from Python for the Pointers in the Structure is crashing Python for me. In other words, I have this structure filled up by a c Function call: class PIX(ctypes.Structure): """Comments not generated """ _fields_ = [ ("w", ctypes.c_uint32), ("h", ctypes.c_uint32), ("d", ctypes.c_uint32), ("wpl", ctypes.c_uint32), ("refcount", ctypes.c_uint32), ("xres", ctypes.c_uint32), ("yres", ctypes.c_uint32), ("informat", ctypes.c_int32), ("text", ctypes.POINTER(ctypes.c_char)), ("colormap", ctypes.POINTER(PIXCOLORMAP)), ("data", ctypes.POINTER(ctypes.c_uint32)) ] And I want to free the memory it is using up from Python code.

• Handling Errors in PHP

  - by Mike

  I have a custom class that, when called, will redirect to a page and send a 'message_type' and 'message' variable via GET. When the page opens it checks for these variables and displays a 'success', 'warning', or 'error' message depending on the 'message_type' variable. I made it so the user thinks they stay on the same page. It also allows for other variables to be passed along with the message. Is this good practice, or should I just start using exceptions? Example: //Call a static function that will redirect to a page, with an error message RedirectWithMessage::go('somepage.php', MessageType::ERROR, 'Error message here.'); The following checkMessage() function is an include file: function checkMessage() { if((isset($_GET['message_type']) && strlen($_GET['message_type'])) && (isset($_GET['message']) && strlen($_GET['message_type']))) { DisplayMessage::display($_GET['message_type'], $_GET['message']); return true; } return false; } On the page that is redirected to, call checkMessage(); //If a message is received, display it. If not, do nothing checkMessage(); I know this might be vague, and I can supply more code if necessary. I guess the issue is that I don't have much experience using exceptions, but I think they seem cumbersome (writing try-catch blocks everywhere). Please let me know if I am making this more difficult for myself or if there is a better solution. Thanks! Mike

• Invalid argument in sendfile() with two regular files

  - by Daniel Hershcovich

  I'm trying to test the sendfile() system call under Linux 2.6.32 to zero-copy data between two regular files. As far as I understand, it should work: ever since 2.6.22, sendfile() has been implemented using splice(), and both the input file and the output file can be either regular files or sockets. The following is the content of sendfile_test.c: #include <sys/sendfile.h> #include <fcntl.h> #include <stdio.h> int main(int argc, char **argv) { int result; int in_file; int out_file; in_file = open(argv[1], O_RDONLY); out_file = open(argv[2], O_WRONLY | O_CREAT | O_TRUNC, 0644); result = sendfile(out_file, in_file, NULL, 1); if (result == -1) perror("sendfile"); close(in_file); close(out_file); return 0; } And when I'm running the following commands: $ gcc sendfile_test.c $ ./a.out infile The output is sendfile: Bad file descriptor Which means that the system call resulted in errno = -EINVAL, I think. What am I doing wrong?

• Rendering Swing Components to an Offscreen buffer

  - by Nick C

  I have a Java (Swing) application, running on a 32-bit Windows 2008 Server, which needs to render it's output to an off-screen image (which is then picked up by another C++ application for rendering elsewhere). Most of the components render correctly, except in the odd case where a component which has just lost focus is occluded by another component, for example where there are two JComboBoxes close to each other, if the user interacts with the lower one, then clicks on the upper one so it's pull-down overlaps the other box. In this situation, the component which has lost focus is rendered after the one occluding it, and so appears on top in the output. It renders correctly in the normal Java display (running full-screen on the primary display), and attempting to change the layers of the components in question does not help. I am using a custom RepaintManager to paint the components to the offscreen image, and I assume the problem lies with the order in which addDirtyRegion() is called for each of the components in question, but I can't think of a good way of identifying when this particular state occurs in order to prevent it. Hacking it so that the object which has just lost focus is not repainted stops the problem, but obviously causes the bigger problem that it is not repainted in all other, normal, circumstances. Is there any way of programmatically identifying this state, or of reordering things so that it does not occur? Many thanks, Nick

• Obtaining YouTube video ID in a URL and inputting selected video ID into a URL

  - by Dave

  I've been having trouble in trying to figure this out. What I am trying to do is, obtain the ID of a video from YouTube, and input the 11 character ID into the css of a div of a specific id by using jquery. I know the URL for the thumbnail of any video, but I just need to be able to change the ID to display different video thumbnails. <script> $(document).ready(function() { function(data){ videoID = data.split('www.youtube.com/v/')[1].split('&amp')[0]; $("#304817679").append(videoID); }); $("#304817679").replaceWith("<div id=\"304817679\" style=\"background: url(http://img.youtube.com/vi/"+ $.function(data) +"/0.jpg) no-repeat middle; width: 15px; height: 150px;\"></div>"); }); }); </script> <div id="304817679"> <div style="display: none;"><object width="248" height="222"><param name="movie" value="http://www.youtube.com/v/vy90n2nNRKQ&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1"></param><param name="wmode" value="transparent"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/vy90n2nNRKQ&amp;rel=0&amp;egm=0&amp;showinfo=0&amp;fs=1" type="application/x-shockwave-flash" width="248" height="222" allowFullScreen="true" wmode="transparent"></embed></object></div> </div> Trying to explain this better, I want the 11 Character YouTube Video ID from the embedded code, and put it into the URL of the thumbnail (http://img.youtube.com/vi/"+ function(data) +"/0.jpg).

• Pass Result of ASIHTTPRequest "requestFinished" Back to Originating Method

  - by Intelekshual

  I have a method (getAllTeams:) that initiates an HTTP request using the ASIHTTPRequest library. NSURL *httpURL = [[[NSURL alloc] initWithString:@"/api/teams" relativeToURL:webServiceURL] autorelease]; ASIHTTPRequest *request = [[[ASIHTTPRequest alloc] initWithURL:httpURL] autorelease]; [request setDelegate:self]; [request startAsynchronous]; What I'd like to be able to do is call [WebService getAllTeams] and have it return the results in an NSArray. At the moment, getAllTeams doesn't return anything because the HTTP response is evaluated in the requestFinished: method. Ideally I'd want to be able to call [WebService getAllTeams], wait for the response, and dump it into an NSArray. I don't want to create properties because this is disposable class (meaning it doesn't store any values, just retrieves values), and multiple methods are going to be using the same requestFinished (all of them returning an array). I've read up a bit on delegates, and NSNotifications, but I'm not sure if either of them are the best approach. I found this snippet about implementing callbacks by passing a selector as a parameter, but it didn't pan out (since requestFinished fires independently). Any suggestions? I'd appreciate even just to be pointed in the right direction. NSArray *teams = [[WebService alloc] getAllTeams]; (currently doesn't work, because getAllTeams doesn't return anything, but requestFinished does. I want to get the result of requestFinished and pass it back to getAllTeams:)

• SHGetFolderPath returns path with question marks in it

  - by Colen

  Hi, Our application calls ShGetFolderPath when it runs, to get the My Documents folder. This normally works great. However, for three users - ???????, Jörg and Jörgen (see if you can spot the pattern!) - the call returns some very strange results. For example, for ???????, the call returns: c:\Users\???????\Documents I assume there's some sort of character encoding shenanigan going on here, possibly related to Unicode, but I don't have any experience with that sort of thing. How can I get a useful path to the folder (and other related folders) out of windows, without grovelling through registry keys for the information? In an email to me, ??????? ("Dmitry"), told me his "my documents" folder was actually located here: C:\Users\43D6~1\Documents So I know there's a way to get a "normal" version of the path out of Windows, I just don't know what it is. Background: Our application is not unicode-aware, and uses standard "char *" strings. How can we get the "normal" path? I'm not opposed to calling the "unicode" version of the function, then converting it to "normal" text, if that's possible. Converting the application entirely to use unicode is not an option here (we don't have the time). Thanks.

• partial entity loading and management in silverlight / wcf ria

  - by Dan Wray

  I have a Silverlight 4 app which pulls entities down from a database using WCF RIA services. These data objects are fairly simple, just a few fields but one of those fields contains binary data of an arbitrarily size. The application needs access to this data basically asap after a user has logged in, to display in a list, enable selection etc. My problem is because of the size of this data, the load times are not acceptable and can approach the default timeout of the RIA service. I'd like to somehow partially load the objects into my local data context so that I have the IDs, names etc but not the binary data. I could then at a later point (ie when it's actually needed) populate the binary fields of those objects I need to display. Any suggestions on how to accomplish this would be welcome. Another approach which has occurred to me whilst writing this question (how often does that happen?!) is that I could move the binary data into a seperate database table joined to the original record 1:1 which would allow me to make use of RIA's lazy loading on that binary data. again.. comments welcome! Thanks.

• Return and Save XML Object From Sharepoint List Web Service

  - by HurnsMobile

  I am trying to populate a variable with an XML response from an ajax call on page load so that on keyup I can filter through that list without making repeated get requests (think very rudimentary autocomplete). The trouble that I am having seems to be potentially related to variable scoping but I am fairly new to js/jQuery so I am not quite certain. The following code doesn't do anything on key up and adding alerts to it tells me that it is executing leadResults() on keyup and that the variable is returning an XML response object but it appears to be empty. The strange bit is that if I move the leadResults() call into the getResults() function the UL is populated with the results correctly. Im beating my head against the wall on this one, please help! var resultsXml; $(document).ready( function() { var leadLookupCaml = "<Query> \ <Where> \ <Eq> \ <FieldRef Name=\"Lead_x0020_Status\"/> \ <Value Type=\"Text\">Active</Value> \ </Eq> \ </Where> \ </Query>" $().SPServices({ operation: "GetListItems", webURL: "http://sharepoint/departments/sales", listName: "Leads", CAMLQuery: leadLookupCaml, CAMLRowLimit: 0, completefunc: getResults }); }) $("#lead_search").keyup( function(e) { leadResults(); }) function getResults(xData, status) { resultsXml = xData; } function leadResults() { xData = resultsXml; $("#lead_results li").remove(); $(xData.responseXML).find("z\\:row").each(function() { var selectHtml = "<li>" + "<a href=\"http://sharepoint/departments/sales/Lists/Lead%20Groups/DispForm.aspx?ID=" + $(this).attr("ows_ID") + ">" + $(this).attr("ows_Title")+" : " + $(this).attr("ows_Phone") + "</a>\ </li>"; $("#lead_results").append(selectHtml); }); }

• Using Javascript to submit forms.

  - by Razor Storm

  I am using a jQuery function to submit a form when a certain button is pressed, however this seems to have no effect on the form. My code is as follows: HTML: <form id="loginForm" action="" method="POST"> <input class="loginInput" type="hidden" name="action" value="login"> <input id="step1a" class="loginInput" type="text" name="username"> <input id="step2a" class="loginInput" type="password" name="password" style="display:none;"> <input id="step1b" class="loginSubmit" onclick="loginProceed();" type="button" name="submit" value="Proceed" title="Proceed" /> <input id="step2b" class="loginSubmit" onclick="submitlogin();" type="button" value="Validate" title="Validate" style="display:none;" /> Javascript: function submitlogin() { $("form").submit(); } However, when I press the button, absolutely nothing occurs. PS. This function may seem meaningless since I can just use a input type="submit" but I originally intended this to have some more functionality, I stripped the function to its bare bones for testing purposes.

• Question about creating device-compatible bitmaps in C#

  - by MusiGenesis

  I am storing bitmap-like data in a two-dimensional int array. To convert this array into a GDI-compatible bitmap (for use with BitBlt), I am using this function: public IntPtr GetGDIBitmap(int[,] data) { int w = data.GetLength(0); int h = data.GetLength(1); IntPtr ret = IntPtr.Zero; using (Bitmap bmp = new Bitmap(w, h)) { for (int x = 0; x < w; x++) { for (int y = 0; y < h; y++) { Color color = Color.FromArgb(data[x, y]); bmp.SetPixel(x, y, color); } } ret = bmp.GetHbitmap(); } return ret; } This works as expected, but the call to bmp.GetHbitmap() has to allocate memory for the returned bitmap. I'd like to modify this method in two (probably related) ways: I'd like to remove the intermediate Bitmap from the above code entirely, and go directly from my int[,] array to the device-compatible bitmap (i.e. the IntPtr). I presume this would involve calling CreateCompatibleBitmap, but I don't know how to go from that call to actually manipulating the pixel values. This should logically follow from the answer to the first, but I'd also like my method to re-use existing GDI bitmap handles (instead of creating a new bitmap each time). How can I do this? NOTE: I don't really use Bitmap.SetPixel(), as its performance could best be described as "glacial". The code is just for illustration.

• function in php for displaying a menu

  - by Stanislas Piotrowski

  I met some trouble with a function I have written. In fact I have an array in which I have different custom values. I would like to display the result of that, so here is my function function getAccess($var){ $data=mysql_fetch_array(mysql_query("SELECT * FROM `acces` WHERE `id`='.$var.'")); return $data; } getAccess($_SESSION['id']); $paramAcces = array( 'comptesfinanciers' => array( 'libelle' => 'COMPTES FINANCIERS', 'acces' => $data['comptesfinanciers'], 'lien' => 'financier', 'image' => 'images/finances.png' ) ); I have done a var_dump of $paramAcces which return array(1) { ["comptesfinanciers"]=> array(4) { ["libelle"]=> string(18) "COMPTES FINANCIERS" ["acces"]=> NULL ["lien"]=> string(9) "financier" ["image"]=> string(19) "images/finances.png" } } (that are the ecpected values). Here is the function for displaying what is in the array /** * AFFICHAGE DE LA SECTION PARAMETRES SUR LA PAGE D'ACCUEIL */ function affichParam($paramAccees){ echo '<ul class="getcash-vmenu"><li><a href="index.php?p='.$paramAccees['lien'].'" class="active"><span class="t"><img src="'.$paramAccees['image'].'"> '.$paramAccees['libelle'].'</span></a></li></ul>'; } The trouble is that actualy it return to me an empty line. I really do not know what I'm wrong doin: I call the function like that: <?php affichParam($paramAccees) ?> In a second time I will add more value, so I think I will have to do a for each loop or something like that. But actualy I just would like to display the first record. Any kind of help will be much apprecitaed

• calling .ajax() from an eventHandler c# asp.ent

  - by ibininja

  Good day...! In the code behind (upload.aspx) I have an event that returns the number of bytes being streamed; and as I debug it, it works fine. I wanted to reflect the numbers returned from the eventHandler on a progress bar and this is where I got lost. I tried using jQuery's .ajax() function. this is how I implemented it: In the EventHandler in my code behind I added this code to call the .ajax() function: Page.ClientScript.RegisterStartupScript(this.GetType(), "UpdateProgress", "<script type='text/javascript'>updateProgress();</script>"); My plan is whenever the eventHandler function changes the values of bytes being streamed it calls the javascript function "updateProgress()" The .ajax() function "UpdateProgress()" is as: function updateProgress() { $.ajax({ type: "POST", url: "upload.aspx/GetData", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", async: true, success: function (msg) { $("#progressbar").progressbar("option", "value", msg.d); } }); } I made sure that the function GetData() is [System.Web.Services.WebMethod] and that it is static as well. so the workflow of what I am trying to implement is as: - Click On Upload button - The Behind code starts executing and EventHandler triggers - The EventHandler calls .ajax() function - The .ajax() function retrieves the bytes being streamed and updates progress bar. When I ran the code; all runs well except that the .ajax() is only executed when upload is finished (and progress bar also updates only when finished upload); even though I call .ajax() function every time in the eventHandler function as reflected above... What am I doing wrong? Am I thinking of this right? is there anything else I should add maybe an updatePanel or something? thank you

• How to TDD Asynchronous Events?

  - by Padu Merloti

  The fundamental question is how do I create a unit test that needs to call a method, wait for an event to happen on the tested class and then call another method (the one that we actually want to test)? Here's the scenario if you have time to read further: I'm developing an application that has to control a piece of hardware. In order to avoid dependency from hardware availability, when I create my object I specify that we are running in test mode. When that happens, the class that is being tested creates the appropriate driver hierarchy (in this case a thin mock layer of hardware drivers). Imagine that the class in question is an Elevator and I want to test the method that gives me the floor number that the elevator is. Here is how my fictitious test looks like right now: [TestMethod] public void TestGetCurrentFloor() { var elevator = new Elevator(Elevator.Environment.Offline); elevator.ElevatorArrivedOnFloor += TestElevatorArrived; elevator.GoToFloor(5); //Here's where I'm getting lost... I could block //until TestElevatorArrived gives me a signal, but //I'm not sure it's the best way int floor = elevator.GetCurrentFloor(); Assert.AreEqual(floor, 5); } Edit: Thanks for all the answers. This is how I ended up implementing it: [TestMethod] public void TestGetCurrentFloor() { var elevator = new Elevator(Elevator.Environment.Offline); elevator.ElevatorArrivedOnFloor += (s, e) => { Monitor.Pulse(this); }; lock (this) { elevator.GoToFloor(5); if (!Monitor.Wait(this, Timeout)) Assert.Fail("Elevator did not reach destination in time"); int floor = elevator.GetCurrentFloor(); Assert.AreEqual(floor, 5); } }
