• ASP.NET trace level

  - by axk

  This question is related to my another question. With trace enabled I can get the following(not quite verbose) trace of a page request: [2488] aspx.page: Begin PreInit [2488] aspx.page: End PreInit [2488] aspx.page: Begin Init [2488] aspx.page: End Init [2488] aspx.page: Begin InitComplete [2488] aspx.page: End InitComplete [2488] aspx.page: Begin PreLoad [2488] aspx.page: End PreLoad [2488] aspx.page: Begin Load [2488] aspx.page: End Load [2488] aspx.page: Begin LoadComplete [2488] aspx.page: End LoadComplete [2488] aspx.page: Begin PreRender [2488] aspx.page: End PreRender [2488] aspx.page: Begin PreRenderComplete [2488] aspx.page: End PreRenderComplete [2488] aspx.page: Begin SaveState [2488] aspx.page: End SaveState [2488] aspx.page: Begin SaveStateComplete [2488] aspx.page: End SaveStateComplete [2488] aspx.page: Begin Render [2488] aspx.page: End Render Reflector shows that System.Web.UI.Page.ProcessRequestMain method which I suppose does the main part of request processing has more conditional trace messges. For example: if (context.TraceIsEnabled) { this.Trace.Write("aspx.page", "Begin PreInit"); } if (EtwTrace.IsTraceEnabled(5, 4)) { EtwTrace.Trace(EtwTraceType.ETW_TYPE_PAGE_PRE_INIT_ENTER, this._context.WorkerRequest); } this.PerformPreInit(); if (EtwTrace.IsTraceEnabled(5, 4)) { EtwTrace.Trace(EtwTraceType.ETW_TYPE_PAGE_PRE_INIT_LEAVE, this._context.WorkerRequest); } if (context.TraceIsEnabled) { this.Trace.Write("aspx.page", "End PreInit"); } if (context.TraceIsEnabled) { this.Trace.Write("aspx.page", "Begin Init"); } if (EtwTrace.IsTraceEnabled(5, 4)) { EtwTrace.Trace(EtwTraceType.ETW_TYPE_PAGE_INIT_ENTER, this._context.WorkerRequest); } this.InitRecursive(null); So there are these EwtTrace.Trace messages which I don't see I the trace. Going deeper with Reflector shows that EtwTrace.IsTraceEnabled is checking if the appropriate tracelevel set: internal static bool IsTraceEnabled(int level, int flag) { return ((level < _traceLevel) && ((flag & _traceFlags) != 0)); } So the question is how do I control these _traceLevel and _traceFlags and where should these trace messages ( EtwTrace.Trace ) go? The code I'm looking at is of .net framework 2.0 @Edit: I guess I should start with ETW Tracing MSDN entry.

• iPhone JSON object releasing itself?

  - by MidnightLightning

  I'm using the JSON Framework addon for iPhone's Objective-C to catch a JSON object that's an array of Dictionary-style objects via HTTP. Here's my connectionDidFinishLoading function: - (void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; [loadingIndicator stopAnimating]; NSArray *responseArray = [responseString JSONValue]; // Grab the JSON array of dictionaries NSLog(@"Response Array: %@", responseArray); if ([responseArray respondsToSelector:@selector(count)]) { NSLog(@"Returned %@ items", [responseArray count]); } [responseArray release]; [responseString release]; } The issue is that the code is throwing a EXC_BAD_ACCESS error on the second NSLog line. The EXC_BAD_ACCESS error I think indicates that the variable got released from memory, but the first NSLog command works just fine (and shows that the data is all there); it seems that only when calling the count message is causing the error, but the respondsToSelector call at least thinks that the responseArray should be able to respond to that message. When running with the debugger, it crashes on that second line, but the stack shows that the responseArray object is still defined, and has 12 objects in it (so the debugger at least is able to get an accurate count of the contents of that variable). Is this a problem with the JSON framework's creation of that NSArray, or is there something wrong with my code?

• Visual Studio project using the Quality Center API remains in memory

  - by Traveling Tech Guy

  Hi, Currently developing a connector DLL to HP's Quality Center. I'm using their (insert expelative) COM API to connect to the server. An Interop wrapper gets created automatically by VStudio. My solution has 2 projects: the DLL and a tester application - essentially a form with buttons that call functions in the DLL. Everything works well - I can create defects, update them and delete them. When I close the main form, the application stops nicely. But when I call a function that returns a list of all available projects (to fill a combo box), if I close the main form, VStudio still shows the solution as running and I have to stop it. I've managed to pinpoint a single function in my code that when I call, the solution remains "hung" and if I don't, it closes well. It's a call to a property in the TDC object get_VisibleProjects that returns a List (not the .Net one, but a type in the COM library) - I just iterate over it and return a proper list (that I later use to fill the combo box): public List<string> GetAvailableProjects() { List<string> projects = new List<string>(); foreach (string project in this.tdc.get_VisibleProjects(qcDomain)) { projects.Add(project); } return projects; } My assumption is that something gets retained in memory. If I run the EXE outside of VStudio it closes - but who knows what gets left behind in memory? My question is - how do I get rid of whatever calling this property returns? Shouldn't the GC handle this? Do I need to delve into pointers? Things I've tried: getting the list into a variable and setting it to null at the end of the function Adding a destructor to the class and nulling the tdc object Stepping through the tester function application all the way out, whne the form closes and the Main function ends - it closes, but VStudio still shows I'm running. Thanks for your assistance!

• edited an .SWF, locally the changes made are okay, but when on server changes are not fully visible

  - by Andy

  Hi, I just edited an .SWF file I have on my website home page for a while now. I update the SWF frequently with new pictures. It's actually a picture slideshow, consisting out of 6 images. I used Adobe Flash CS4 Pro to edit the file, with just swapping all the pictures (JPGS) in it for other ones. I also have some small AS where I just have the URL: on(release) { getURL("link"); } so that's nothing fancy at all. I saved and published everything (CTRL+ENTER) and the .SWF played well, and tested it in IE8 and FF. Then I uploaded the SWF to my test server, overwriting the existing SWF file. Now the problem: all pictures but one show up well. Of the 6 images, the second image is actually the old image that was in its place. I downloaded the .SWF from the testserver and inspected the SWF and guess what: the old picture wasn't in it, instead the correct image was in the SWF. Even after reloading the page hitting CTRL+F5 still the wrong image shows. FF though shows the SWF correctly. So I then opened the page on another computer using IE8 and there the SWF works well, showing the correct second image. What's wrong with my first computer's browser? It's also the computer I edited the SWF with. I DO remember like I first saved and uploaded the wrong SWF (with the old 2nd image still in it) to the testserver, and later on uploading the correct one (proper 2nd image) I think IE8 has cached the wrong SWF, and now memorized it someway not willing to see that the file has actually been changed, but what to do so IE8 starts showing the correct SWF??

• SQL Server restore a backup results in an error.

  - by Mario

  I have a database in dev (SQL Server 2005 on Windows Server 2008) that I need to move to prod (SQL Server 2000 on Windows Server 2003). My process is as follows: Login to dev, open SQL Server Management Studio Right click on the database | Tasks | Backup. Keep all default options (full backup etc.) Move .bak file locally to prod (no network drive), login to prod, open SQL Server Enterprise Manager. Right click Databases node | All Tasks | Restore database. Change Restore as database to reflect the same database name. Click radio button 'From device'. Click 'Select Devices' Click Restore from: Add..., browse to .bak file (small - only 6mb) Now I am ready to restore the database, so I click OK and get the following error: "The media family on device 'E:...bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE DATABASE is terminating abnormally." This error is immediate. I have tried a few different variations of this - restoring the db to dev machine with a different db name and log file names (where it originated), creating an empty database with the same physical path to files before and trying to restore to that, making a few different .bak files and making sure they are verified before uploading them to prod. I know for a fact the directory for the .mdf and .ldf files exist on prod, though the files themselves don't exist. If, before I click OK to restore, go to the options tab instead I get the following error: Error 3241: The media family on device 'E:...bak' is incorrectly formed. SQL Server cannot process this media family. RESTORE FILELIST is terminating abnormally. Anyone have any bright ideas?

• openCV Won't copy to image after changed color ( opencv and c++ )

  - by user1656647

  I am a beginner at opencv. I have this task: Make a new image Put a certain image in it at 0,0 Convert the certain image to gray scale put the grayscaled image next to it ( at 300, 0 ) This is what I did. I have a class imagehandler that has constructor and all the functions. cv::Mat m_image is the member field. Constructor to make new image: imagehandler::imagehandler(int width, int height) : m_image(width, height, CV_8UC3){ } Constructor to read image from file: imagehandler::imagehandler(const std::string& fileName) : m_image(imread(fileName, CV_LOAD_IMAGE_COLOR)) { if(!m_image.data) { cout << "Failed loading " << fileName << endl; } } This is the function to convert to grayscale: void imagehandler::rgb_to_greyscale(){ cv::cvtColor(m_image, m_image, CV_RGB2GRAY); } This is the function to copy paste image: //paste image to dst image at xloc,yloc void imagehandler::copy_paste_image(imagehandler& dst, int xLoc, int yLoc){ cv::Rect roi(xLoc, yLoc, m_image.size().width, m_image.size().height); cv::Mat imageROI (dst.m_image, roi); m_image.copyTo(imageROI); } Now, in the main, this is what I did : imagehandler CSImg(600, 320); //declare the new image imagehandler myimg(filepath); myimg.copy_paste_image(CSImg, 0, 0); CSImg.displayImage(); //this one showed the full colour image correctly myimg.rgb_to_greyscale(); myimg.displayImage(); //this shows the colour image in GRAY scale, works correctly myimg.copy_paste_image(CSImg, 300, 0); CSImg.displayImage(); // this one shows only the full colour image at 0,0 and does NOT show the greyscaled one at ALL! What seems to be the problem? I've been scratching my head for hours on this one!!!

• When I use a form to call a method on the controller, I want the page to refresh, and the url to sho

  - by MedicineMan

  Using ASP MVC, I have set up a webpage for localhost/Dinner/100 to show the dinner details for dinner with ID = 100. On the page, there is a dropdown that shows Dinner 1, Dinner 2, etc. The user should select the dinner of interest (Dinner 2, ID = 102) off the form and press submit. The page should refresh and show the url: localhost/Dinner/102, and show the details of dinner 2. My code is working except for the url. During this, my url shows localhost/Dinner/100 even though it is correctly displaying the details of Dinner 2 (ID = 102). My controller method is pretty simple: public ActionResult Index(string id) { int Id = 0; if (!IsValidFacilityId(id) || !int.TryParse(id, out Id)) { return Redirect("/"); } return View(CreateViewModel(Id)); } can you help me figure out how to get this all working? p.s. I did create a custom route for the method: routes.MapRoute( "DinnerDefault", // Route name "Dinner/{id}", // URL with parameters new { controller = "Dinner", action = "Index", id = "" } // Parameter defaults );

• Problems with QDialog in Qt

  - by Martin

  I'm using Qt for Symbian. I have some problems with a QDialog that I open from a QMenu. The QDialog shows up fine and in the QDialog I have a QDialogButtonBox with a button to Close the QDialog. BUT if I close the QDialog and then open it from the QMenu again, it will show up but the button from the QDialogButtonBox will not show up. Instead the buttons from the QMainWindow will show but they are grayed out. How can I get the QDialog buttons to show every time? Maybe I have some problems with setting focus on the QDialog? I really can't see what I'm doing wrong here. It's not much code that I use, you can try it yourself. This is my code: In QMainWindow I use the following to create the menu: QAction *menuButton = new QAction("Menu", this); menuButton->setSoftKeyRole(QAction::PositiveSoftKey); QMenu *menu = new QMenu(this); menuButton->setMenu(menu); QAction *popup = new QAction("Show popup",this); connect(popup, SIGNAL(triggered()), this, SLOT(showPopup())); menu->addAction(popup); addAction(menuButton); This shows the QDialog: void MyMainWindow::showPopup(){ TestDialog *test = new TestDialog(this); test->setAttribute(Qt::WA_DeleteOnClose); test->show(); } This is the TestDialog: TestDialog::TestDialog(QWidget *parent) : QDialog(parent) { ui.setupUi(this); QDesktopWidget* desktopWidget = QApplication::desktop(); QRect rect = desktopWidget->availableGeometry(); this->setFixedWidth(rect.width()); }

• What service do you use for music on hold?

  - by Russ Warren

  This may not be a sysadmin question for some, but it is definitely a hurdle I have to jump as the sysadmin for my company. We recently rolled-out a company wide VoiP system (Switchvox, to be exact) that has come preloaded with some royalty-free music on hold. Our customers have been complaining that the music on hold sounds like "funeral music." This may be the case (although I wouldn't want it played at my funeral), but it is all we have and we aren't willing to be sued over using music that isn't properly licensed. So, that brings me to the question asked in the title -- what and/or how do you provide decent music on hold? I'm assuming many people here use a PBX that allows customized music, so this has to apply to many of you. We've been looking at some sites that allow you to download royalty-free music for a one-time fee, but the music seems...lame. Something like a one-year subscription from ibaudio.com seems to be the best bet so far. Have you been able to discover something a little more mainstream for a decent licensing fee? Thank you. EDIT: Our PBX allows the playback of MP3 and OGG files, but does not allow streaming of a live audio source, Internet-based or otherwise. It also does not allow the use of a "line-in" source such as a CD player or radio. Don't let this stop you from sharing your setup, though. I'm interested in hearing what everyone uses!

• iPhone programming - problem with CoreFoundation forking, PLEASE for the love of god help! lol

  - by Tom

  Hello all, I've been working on an iPhone for several months. It's a 2d shooting game akin to the old Smash TV type games. I'm doing everything alone and it has come out well so far, but now I am getting unpredictable crashes which seem to be related to CoreFoundation forking and not exec()ing, as the message THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONA LITY_YOU_MUST_EXEC__ always shows up somewhere in the debugger. Usually it shows up around a CFRunLoopRunSpecific and is related to either a timer firing or _InitializeTouchTapCount. I cannot figure out exactly what is causing the fork to occur. My main game loop is running on a timer, first updating all the logic and then drawing everything with openGL. There is nothing highly complex or unusual. I understand you cannot make CF calls on the childside of a fork, or access shared memory and things like that. I am not explicitly trying to fork anything. My question is: can anyone tell me what type of activity might cause CoreFoundation to randomly fork like this? I'd really like to finish this game and I don't know how to solve this problem. Thanks for any help.

• how to make a explorer like logic in Obj C for iphone

  - by Ekra

  Hi friends, To make the query simple first we can take example:- If we open the explorer in our Windows desktop how it shows us the tree. As we keep on clicking the tree it get expanded and shows the file in it. The same way I want to show a explorer which gets expanded as the user clicks on it(I want to get the business logic the UI is simple). The information of the explorer i.e. which folder has what files come in a XML format to me. I have 2 options of getting the XML either I can get the whole XML at one query(but I guess this might slow the application if the XML is quite big). OR I can get the XML for every list like first only the root structure then if user clicks on any folder in root I can get the list(the files or folders inside that folder) of that particular folder. Now the question is What would be the approach to implement both the method and which would be the best. Should I need to create some dictionary to maintain the link of the files like which file is inside what. I am not able to get as how I would be able to link all the files. Any hint or direction would be highly appreciated. Thanks in advance

• How to automatically expand html select element in javascript

  - by xan

  I have a (hidden) html select object in my menu attached to a menu button link, so that clicking the link shows the list so you can pick from it. When you click the button, it calls some javascript to show the <select>. Clicking away from the <select> hides the list. What I really want is to make the <select> appear fully expanded, as if you had clicked on the "down" arrow, but I can't get this working. I've tried lots of different approaches, but can't make any headway. What I'm doing currently is this: <li> <a href="javascript:showlist();"><img src="/images/icons/add.png"/>Add favourite</a> <select id="list" style="display:none; onblur="javascript:cancellist()"> </select> </li> // in code function showlist() { //using prototype not jQuery $('list').show(); // shows the select list $('list').focus(); // sets focus so that when you click away it calles onblur() } I've tried calling $('list').click(). I've tried setting onfocus="this.click()" But in both cases I'm getting Uncaught TypeError: Object # has no method 'click' which is peculiar as link text says that it supports the standard functions. I've tried setting the .size = .length which works, but doesn't have the same appearance (as when you click to open the element, it floats over the rest of the page.) Does anyone have any suggestions?

• Python API for VirtualBox

  I have made a command-line interface for virtualbox such that the virtualbox can be controlled from a remote machine. now I am trying to implement the commmand-line interface using python virtualbox api.

• Display ñ on a C# .NET application

  - by mmr

  I have a localization issue. One of my industrious coworkers has replaced all the strings throughout our application with constants that are contained in a dictionary. That dictionary gets various strings placed in it once the user selects a language (English by default, but target languages are German, Spanish, French, Portuguese, Mandarin, and Thai). For our test of this functionality, we wanted to change a button to include text which has a ñ character, which appears both in Spanish and in the Arial Unicode MS font (which we're using throughout the application). Problem is, the ñ is appearing as a square block, as if the program did not know how to display it. When I debug into that particular string being read from disk, the debugger reports that character as a square block as well. So where is the failure? I think it could be in a few places: 1) Notepad may not be unicode aware, so the ñ displayed there is not the same as what vs2008 expects, and so the program interprets the character as a square (EDIT: notepad shows the same characters as vs; ie, they both show the ñ. In the same place.). 2) vs2008 can't handle ñ. I find that very, very hard to believe. 3) The text is read in properly, but the default font for vs2008 can't display it, which is why the debugger shows a square. 4) The text is not read in properly, and I should use something other than a regular StreamReader to get strings. 5) The text is read in properly, but the default String class in C# doesn't handle ñ well. I find that very, very hard to believe. 6) The version of Arial Unicode MS I have doesn't have ñ, despite it being listed as one of the 50k characters by http://www.fileinfo.info. Anything else I could have left out? Thanks for any help!

• Failure to register .dll with regsvr32 - only in Release build.

  - by Hendrik

  Hi, I'm having a weird problem when trying to register the .dll i created using regsvr32. During development everything went fine, the debug version registers and works fine. Now i wanted to create a Release version, but that Version does not register anymore. regsvr32 comes up with the following error: The module "mpegsplitter.dll" failed to load. Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified procedure could not be found. Some research brought me to the dependency walker, which does tell me this Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module. It also does show a dependency on "crtdll.dll" that the debug version does not have (The function view shows soem functions that normally should be in ole32.dll), which is colored red'ish. So far so good, i guess its somehow related to what the dependency walker shows there. But where do i go from here? How do i fix it? Any help would be greatly appreciated, that has been keeping me busy for several hours already. Thanks!

• Problem with XML encoding of database contents with Latin characters

  - by user89691

  I have an ASP Access database that contains strings in various European languages. The database was populated prior by agents in the respective countries. It contains entries with accented etc characters as you would expect. If I open the database with MS Access these characters show up fine. For example the the German equivalent of "Open" shows as "Öffnen" (hopefully you can see an "O" with 2 dots above it!). I have ASP code that reads the database and returns records in XML. The text is passed to XMLEncode to construct the XML, but that only seems to deal with the 5 specials like "<", "&", etc. If I dump the XML the accented characters are unchanged. <English>Open</English> <German>Öffnen</German> If I look at the raw packets with Wireshark I see that the "Ö" byte is hex D6, which appears to be it's decimal Unicode and ISO 8859-1 value. The problem starts when I try to parse the XML in client-side JS. I get: "An invalid character was found in text content" from IE. FF and Chrome happily accept the XML without hiccup but the browser shows the "Ö" character as a diamond with a question mark inside. http://www.validome.org/xml/validate/ reports "encoding error." http://www.w3schools.com/dom/dom_validate.asp thinks it is fine. The XML is UTF-8 encoded. What do I need to do to have IE accept my XML without complaint? What do I need to do to have browsers display the stuff correctly?

• Can't get MySQL source query to work using Python mysqldb module

  - by Chris

  I have the following lines of code: sql = "source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql" cursor.execute (sql) When I execute my program, I get the following error: Error 1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'source C:\My Dropbox\workspace\projects\hosted_inv\create_site_db.sql' at line 1 Now I can copy and past the following into mysql as a query: source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql And it works perfect. When I check the query log for the query executed by my script, it shows that my query was the following: source C:\\My Dropbox\\workspace\\projects\\hosted_inv\\create_site_db.sql However, when I manually paste it in and execute, the entire create_site_db.sql gets expanded in the query log and it shows all the sql queries in that file. Am I missing something here on how mysqldb does queries? Am I running into a limitation. My goal is to run a sql script to create the schema structure, but I don't want to have to call mysql in a shell process to source the sql file. Any thoughts? Thanks!

• Where is my Drupal View pager?

  - by anotherthink

  Hi, I have a Drupal 6 site where I've created a view that shows a list of nodes. Nothing complicated -- except that when I choose "use pager" -- "yes" (and choose the "full pager" option), the pager doesn't show up on the page. The first page of nodes shows up, but there's no way to get to other pages. Through googling, I saw that some people had an issue with the "Pager Element" item, so I changed that from 0 to 1 -- no luck. This shouldn't be very complicated, but I've been at it for a while! Help!? ETA: I've tracked it down to the following lines in /modules/views/theme/theme.inc: $pager_theme = views_theme_functions($pager_type, $view, $view->display_handler->display); $vars['pager'] = theme($pager_theme, $exposed_input, $view->pager['items_per_page'], $view->pager['element']); The first line returns an array; the second line returns nothing. I suspect now that this is a theming problem with the custom theme I'm using that may not have fully been correctly updated for Drupal 6 -- like, maybe I'm missing a pager template somehow? -- however, I'm quite new to Drupal and don't really understand how to further track down and fix the issue. Any advice would be much appreciated! ETA yet again: The pager also doesn't show up when using Garland, so it's not a theme issue after all. ALSO: I have a copy of this site set up on a development server as well, and that copy has working pagination! I've checked what I thought might be different -- files in the theme, what modules are enabled -- and it seems like pretty much everything is the same. The one thing that I know is different, however, is that the production server has a lower version of MySQL (lower than recommended for Drupal 6 -- we're waiting on the hosting company being able to change this later). Would it make sense that the old version of MySQL is unable to do pagination correctly in Drupal 6? If so, does anyone know a workaround I can do until we are able to update MySQL?

• IE6 background-position(?) issue

  I apply to stackoverflow as my last resort. I got this ie6 bug while using the image at the background of the link. It seems that ie6 scrolls the background. How can I avoid it? At some width it shows like this: And at some other it shows like that: IE7 & FF show this just like I expect: The links are placed inside the div which is floating to the right. <a href="/tr" class="menuLink" style="background-image:url(/img/tr.png);">TR</a> <a href="/eng" class="menuLink" style="background-image:url(/img/eng.png); margin-right:30px;">ENG</a> <a href="/logout" class="menuLink" style="background-image:url(/img/logout.png);"><?=$ui["exit"];?></a> .menuLink { font-family:"Tahoma"; font-size:11px; color:#003300; text-decoration:underline; font-weight: bold; background-position:0% 50%; background-repeat:no-repeat; } .menuLink:hover { font-size:11px; color:#047307; text-decoration:underline; font-weight: bold; } Any hints how can I avoid this?

• Comet Jetty/Tomcat, having some browser issues with Firefox and Chrome

  - by ages04

  I am exploring the use of Comet for a project I am working on. I tried creating a test application first using Tomcat6 and CometProcessor API and then with Jetty7 Continuations. The application is kind of working on both but I am having some issues with the actual display of messages. I used the technique of creating an XMLHttpRequest Connection and keeping it open all the time so the server can continuously push data to all the clients connected whenever it is available. My client side code is something similar to this: function fn(){ var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function(){ if (xhr.readyState==3){ document.getElementById('dv').innerHTML =(xhr.responseText); } if (xhr.readyState==4){ alert ('done'); } } xhr.open("GET", "First", true); xhr.send(null); } I found this thing of using readyState 3 somewhere online. I am facing 2 problems currently: In Firefox this code works perfectly. But if I open a new tab or even a new browser window, it does not make a new connection to the server and nothing shows up on the new tab or window, only the first tab/window gets the display. I used wireshark to check this and its shows only 1 connection even after the 2nd tab is opened. I am unable to understand why this would happen. I have read about the 2 connection limit, but here there is only one connection. Secondly in Chrome, the above code does not work, and the callback is not invoked for readystate of 3, only when the connection is closed by the server i get the output. I would also like to ask which is the best way/framework for doing Comet with Java. I am currently using jQuery on the client side. Any suggestions would be greatly appreciated!! Thanks

• Accessing frame info in gdb

  - by Maelstrom

  In gdb, is there a way to access the contents of info frame in a script? I'm debugging a problem somewhere between Apache, PHP, APC and my own code, and I have about a hundred cores to choose from. Following the instructions here http://bugs.php.net/bugs-generating-backtrace.php I end up with a stacktrace like: #0 0x0121a31a in do_bind_function (opline=0xa94dd750, function_table=0x9b9cf98, compile_time=0 '\0') at /usr/src/debug/php-5.2.7/Zend/zend_compile.c:2407 #1 0x0124bb2e in ZEND_DECLARE_FUNCTION_SPEC_HANDLER (execute_data=0xbfef7990) at /usr/src/debug/php-5.2.7/Zend/zend_vm_execute.h:498 #2 0x01249dfa in execute (op_array=0xb79d5d3c) at /usr/src/debug/php-5.2.7/Zend/zend_vm_execute.h:92 #3 0x01261e31 in ZEND_INCLUDE_OR_EVAL_SPEC_VAR_HANDLER (execute_data=0xbfef80d0) at /usr/src/debug/php-5.2.7/Zend/zend_vm_execute.h:7809 #4 0x01249dfa in execute (op_array=0xb79d55ec) at /usr/src/debug/php-5.2.7/Zend/zend_vm_execute.h:92 ... #26 0x09caa894 in ?? () #27 0x00000000 in ?? () The stack will always look similar, with function execute and ZEND_something interleaved several times. I need to go up to the last instance of execute (up 2 in this case) and print myVar. Obviously gdb knows the function names, but does it surface them in any user variables I could access? Typing frame 2 shows a one-line version, and info frame shows a single stackframe in detail. I want to do something like while ($current_frame.function_name != "execute") {up;} print myVar but I don't see how to do it strictly within gdb. Is there a variable / structure / special memory location / something that allows access to gdb's information on either the whole stack (like bt) or to the current stack frame (like info frame)?

• MSMQ on Win2008 R2 won’t receive messages from older clients

  - by Graffen

  Hi all I'm battling a really weird problem here. I have a Windows 2008 R2 server with Message Queueing installed. On another machine, running Windows 2003 is a service that is set up to send messages to a public queue on the 2008 server. However, messages never show up on the server. I've written a small console app that just sends a "Hello World" message to a test queue on the 2008 machine. Running this app on XP or 2003 results in absolutely nothing. However, when I try running the app on my Windows 7 machine, a message is delivered just fine. I've been through all sorts of security settings, disabled firewalls on all machines etc. The event log shows nothing of interest, and no exceptions are being thrown on the clients. Running a packet sniffer (WireShark) on the server reveals only a little. When trying to send a message from XP or 2003 I only see an ICMP error "Port Unreachable" on port 3527 (which I gather is an MQPing packet?). After that, silence. Wireshark shows a nice little stream of packets when I try from my Win7 client (as expected - messages get delivered just fine from Win7). I've enabled MSMQ End2End logging on the server, but only entries from the messages sent from my Win7 machine are appearing in the log. So somehow it seems that messages are being dropped silently somewhere along the route from XP or 2003 to my 2008 server. Does anyone have any clues as to what might be causing this mysterious behaviour? -- Jesper

• Due Date set via EWS is wrong in reminder popup

  - by Paul McLean

  I'm having some trouble using EWS with tasks and reminders, specifically, the due date. When I run my code, shown below, the task is added to my exchange account and I can see it fine in outlook. All the data in it looks fine too. However, if I specify to have a reminder for the task, the due date it shows is very wrong. It's usually 17 hours in the future, but the screenshot I've provided shows it being 19 hours in the future. I'm finding it very strange that if I open the task, the due date looks fine, but the reminder is saying it is due well into the future. Any ideas? Screenshot: http://s970.photobucket.com/albums/ae187/paulehn/?action=view&current=ewstask.jpg ExchangeVersion exchVersion = new ExchangeVersion(); exchVersion = ExchangeVersion.Exchange2007_SP1; ExchangeService service = new ExchangeService(exchVersion); service.UseDefaultCredentials = true; service.Url = new Uri("https://mail.domain.com.au/ews/exchange.asmx"); Task task = new Task(service); task.Subject = "Subject"; task.Body = new MessageBody(BodyType.HTML, "Body"); task.StartDate = DateTime.Today; task.DueDate = DateTime.Now.AddHours(2); task.ReminderDueBy = DateTime.Now; task.ReminderMinutesBeforeStart = 15; task.IsReminderSet = true; task.Save();

• Vimeo Desktop App OAuth

  - by Barry

  Hi Guys, I'm currently having massive trouble with Vimeo's Oauth implementation and my desktop app. My program does the following correctly. 1- Requests a Unauthorized Request Token with my key and secret and returns - a Token and a Token secret. 2- Generates a URL for the user to go to using the token which then shows our application's name and allows the user to Authorize us to use his/her account. It then shows a verifier which the user returns and puts into our app. The problem is the third step and actually exchanging the tokens for the access tokens. Basically every time we try and get them we get a "Invalid / expired token - The oauth_token passed was either not valid or has expired" I looked at the documentation and there's supposed to be a callback to a server when deployed like that which gives the user an "authorized token" but as im developing a desktop app we can't do this. So I assume the token retrieved in 1 is valid for this step. (actually it seems it is: http://vimeo.com/forums/topic:22605) So I'm wondering now am I missing something here on my actual vimeo application account now? is it treating it as a web hosted app with callbacks? all the elements are there for this to work and I've used this same component to create a twitter Oauth login in exactly the same way and it was fine. Thanks in advance, Barry

• can't properly shutdown ubuntu and sound problem on HP mini 311 netbook

  - by Viele

  hi, I recently bought a HP mini 311 netbook. I replaced its harddrive and installed ubuntu 10.04. Since then, I have encountered some very strange problem with its sound and shutdown/reboot. At times, when I start the computer, it will have no sound, on the GUI the sound is at max, but no sound is available. This sometimes also happen after after upgrades, hibernate, and toggling the wireless radio button. Strangely, when the sound is out the device will also refuse to be shutdown. If I shutdown the computer using the GUI, it will simply go back to the log in screen without actually shutting down. If I use "sudo shutdown 0", the computer will hang on the loading screen of the shut down process. I had to force the pc to shutdown by holding the power button down. usually (probably always) after I force a turn-off then start off again. the sound and shutdown become normal. I wonder if anyone have clues regarding to the cause of this problem. This the info about the computer: 1) installed ubuntu 10.04LTS RC, later upgraded to formal released version. 2) cat /proc/asound/version == "Advanced Linux Sound Architecture Driver Version 1.0.21." however, when doing 'alsaconf' the version displayed is 1.0.23 any help is appreciated. Thanks
