  • Google Chrome and (cache or memory leaks).

    - by Alexey Ogarkov
    Hello All, I have a big problem with Google Chrome and its memory. My app is displaying to user several image charts and reloads them every 10s. In the interval i have code like that var image = new Image(); var src = 'myurl/image'+new Date().getTime(); image.onload = function() { document.getElementById('myimage').src = src; image.onload = image.onabort = image.onerror = null; } image.src = src; So i have no memory leaks in Firefox and IE. Here the response headers for images Server Apache-Coyote/1.1 Vary * Cache-Control no-store (// I try no-cache, must-revalidate and so on here) Content-Type image/png Content-Length 11131 Date Mon, 31 May 2010 14:00:28 GMT Vary * taken from here In about:cache page there is no my cached images. If i enable purge-memory-button for chrome (--purge-memory-button parameter) it`s not help. Images is in PNG24. So i think that the problem is not in cache. May be Google Chrome is not releasing memory for old images. Please help. Any suggestions. Thanks.

  • .Net 2.0 ServiceController.GetServices()

    - by Miles
    I've got a website that has windows authentication enable on it. From a page in the website, the users have the ability to start a service that does some stuff with the database. It works fine for me to start the service because I'm a local admin on the server. But I just had a user test it and they can't get the service started. My question is: Does anyone know of a way to get a list of services on a specified computer by name using a different windows account than the one they are currently logged in with? I really don't want to add all the users that need to start the service into a windows group and set them all to a local admin on my IIS server..... Here's some of the code I've got: public static ServiceControllerStatus FindService() { ServiceControllerStatus status = ServiceControllerStatus.Stopped; try { string machineName = ConfigurationManager.AppSettings["ServiceMachineName"]; ServiceController[] services = ServiceController.GetServices(machineName); string serviceName = ConfigurationManager.AppSettings["ServiceName"].ToLower(); foreach (ServiceController service in services) { if (service.ServiceName.ToLower() == serviceName) { status = service.Status; break; } } } catch(Exception ex) { status = ServiceControllerStatus.Stopped; SaveError(ex, "Utilities - FindService()"); } return status; } My exception comes from the second line in the try block. Here's the error: System.InvalidOperationException: Cannot open Service Control Manager on computer 'server.domain.com'. This operation might require other privileges. --- System.ComponentModel.Win32Exception: Access is denied --- End of inner exception stack trace --- at System.ServiceProcess.ServiceController.GetDataBaseHandleWithAccess(String machineName, Int32 serviceControlManaqerAccess) at System.ServiceProcess.ServiceController.GetServicesOfType(String machineName, Int32 serviceType) at TelemarketingWebSite.Utilities.StartService() Thanks for the help/info

  • How to eliminate tearing from animation?

    - by MusiGenesis
    I'm running an animation in a WinForms app at 18.66666... frames per second (it's synced with music at 140 BPM, which is why the frame rate is weird). Each cel of the animation is pre-calculated, and the animation is driven by a high-resolution multimedia timer. The animation itself is smooth, but I am seeing a significant amount of "tearing", or artifacts that result from cels being caught partway through a screen refresh. When I take the set of cels rendered by my program and write them out to an AVI file, and then play the AVI file in Windows Media Player, I do not see any tearing at all. I assume that WMP plays the file smoothly because it uses DirectX (or something else) and is able to synchronize the rendering with the screen's refresh activity. It's not changing the frame rate, as the animation stays in sync with the audio. Is this why WMP is able to render the animation without tearing, or am I missing something? Is there any way I can use DirectX (or something else) in order to enable my program to be aware of where the current scan line is, and if so, is there any way I can use that information to eliminate tearing without actually using DirectX for displaying the cels? Or do I have to fully use DirectX for rendering in order to deal with this problem? Update: forgot a detail. My app renders each cell onto a PictureBox using Graphics.DrawImage. Is this significantly slower than using BitBlt, such that I might eliminate at least some of the tearing by using BitBlt?

  • Why does my javascript file sometimes compressed while sometimes not?(IIS Gzip problem)

    - by Kevin Yang
    i enable gzip for javascript file in my iis settings, here 's the corresponding config section. <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" staticCompressionLevel="10" dynamicCompressionLevel="8" /> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/soap+msbin1" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </staticTypes> </httpCompression> currently, when i download my js file, it seems that sometimes server return the gzip one, and sometimes not. i dont know why, and how to debug that. If a file is already gzipped, it should be cached in local disk, and next time someone visit that file again, iis kernel should return the cache gzip file directly without compressing it again. Is that right?

  • Heterogeneous queries require the ANSI_NULLS

  • Pattern for UI configuration

    - by TERACytE
    I have a Win32 C++ program that validates user input and updates the UI with status information and options. Currently it is written like this: void ShowError() { SetIcon(kError); SetMessageString("There was an error"); HideButton(kButton1); HideButton(kButton2); ShowButton(kButton3); } void ShowSuccess() { SetIcon(kError); std::String statusText (GetStatusText()); SetMessageString(statusText); HideButton(kButton1); HideButton(kButton2); ShowButton(kButton3); } // plus several more methods to update the UI using similar mechanisms I do not likes this because it duplicates code and causes me to update several methods if something changes in the UI. I am wondering if there is a design pattern or best practice to remove the duplication and make the functionality easier to understand and update. I could consolidate the code inside a config function and pass in flags to enable/disable UI items, but I am not convinced this is the best approach. Any suggestions and ideas?

  • Is Accessing USB from web application for cross browser cross os possible at all ?

    - by Ved
    Hey Guys, I am wondering if there is anyway we can achieve this. I heard different things about Silverlight 4 , Java Script or Active X control but not seen any demo of code for any of them. Does anyone know any web component that is available or how to write one. We really like capture client's USB drive via Web and read/write data on it. This has to work for ANY Operating system in Any web browser. Thanks UPDATED What about WPF in browser mode...I read that I can host my wpf apps inside browser and sort of like smart client. Here is a great example of doing this via silverlight 4 but author mentions about possibility of accessing USB on MAC via 1) Enable executing AppleScripts. This option will let us have the same amount of control on a mac machine as we do on a windows machine. 2) Add an overload to ComAutomationFactory.CreateObject() that calls the “Tell Application” command under the scenes and gets a AppleScript object. This option would work extremely well for Office automation. For any other operating system feature, you’ll have to code OS access twice.  I did not quite understand it. Has any tried this ?

  • Multiple Facebook scripts?

    - by J Set
    This may be kind of a dumb question, but the script for the facebook button on the like button page is different from the script on the javascript sdk page, but similar. Did facebook just forget to update the documentation or do I need both scripts? The like button page gives: <div id="fb-root"></div> <script> (function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> But on the javascript sdk page: <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : 'YOUR_APP_ID', // App ID channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true // parse XFBML }); // Additional initialization code here }; // Load the SDK Asynchronously (function(d){ var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); }(document)); </script>

  • How to disable server-side caching on IIS 7.5 (asp net mvc3)

    - by troebr
    I'm struggling with my IIS setup regarding caching, here's a brief description of my problem: I'm making a site for mobile and non-mobile, sharing the same controllers. IE: mysite/page will serve either mysite/page.cshtml, or mysite/M/page.cshtml, depending on the device. Here's the catch, it worked fine with my local and integration environment (cassiini and iis 6), but on another machine (2008r2/iis 7.5), apparently there is an aggressive server-side caching policy: If I access the website from a desktop machine, I have the correct pages (desktop version) If now I use my mobile phone to access the site, I will have the desktop version, (which implies a server-side cache, my phone is not using the same network). On the contrary, if I were to restart the server and access the site using my phone first, then I will get the mobile version on my desktop (only for the pages I already visited of course). I tried 2 solutions so far: Disabling OutputCache from my Web.config: <httpModules> [..] <remove name="OutputCache" /> </httpModules> And unchecking "Enable output cache" in "Output Caching" for my site in IIS. What's bugging me is that I do not have this problem with my other server (iis 6.0), although caching is enabled on this one, which leads me to think it is related to iis 7 caching addition. My question is simple: how does one disable server-side caching on IIS 7.5? Thanks in advance for your iis lights!

  • How to tell what account my webservice is running under in Visual Studio 2005

    - by John Galt
    I'm going a little nuts trying to understand the doc on impersonation and delegation and the question has come up what account my webservice is running under. I am logged as myDomainName\johna on my development workstation called JOHNXP. From Vstudio2005 I start my webservice via Debug and the wsdl page comes up in my browser. From Task Manager, I see the following while sitting at a breakpoint in my .asmx code: aspnet_wp.exe pid=1316 UserName=ASPNET devenv.exe pid=3304 UserName=johna The IIS Directory Security tab for the Virtual Directory that hosts my ws.asmx code has "Enable Anonymous access" UNCHECKED and has "Integrated Windows Authentication" CHECKED. So when the MSDN people state "you must configure the user account under which the server process runs", what would they be refering to in the case of my little webservice described above? I am quoting from: http://msdn.microsoft.com/en-us/library/aa302400.aspx Ultimately, I want this webservice of mine to impersonate whatever authenticated domain user browses through to an invoke of my webservice. My webservice in turn consumes another ASMX webservice on a different server (but same domain). I need this remote webservice to use the impersonated domain user credentials (not those of my webservice on JOHNXP). So its getting a little snarly for me to understand this and I see I am unclear about the account my web service uses. I think it is ASPNET in IIS 5.1 on WinXP but not sure.

  • Python CGI Premature end of script error depending on script parameters.

    - by nickengland
    I have a python script which should parse a file and produce some output to disk, as well as returning a webpage linking to the outputted files. When run with a file posted from the HTML form I get no HTML output back, just a 500 error page and the error_log contains the line: [Mon Apr 19 15:03:23 2010] [error] [client xxx.xxx.121.79] Premature end of script headers: uploadcml.py, referer: http://xxx.ch.cam.ac.uk:9000/ However, the files which the script should be saving are indeed saved to disk. If I run it without any arguments, the script returns the correct HTML indicating no file was parsed. All the information I have found on the web about Premature end of script headers implies it is due to either a missing header, or lack of permissions on the python script but neither can apply to me. The first lines of the script are: #!/home/nwe23/bin/bin/python import cgitb; cgitb.enable() import cgi import pybel,openbabel import random print "Content-Type: text/html" print so when run, I can see no way for it to fail to output the header, and it DOES output the header when run without a file to parse, but when given a file produces the error(but still parsed the file and saves the output to disk!). Does anyone know how this is happening and what can be done to fix it? I have tried adding wrongly-indented gibberish (such as foobar) at various points in the file, and this results in adding an indent error to the error_log wherever it is, even if its the very last line in the script. The Premature script headers error remains though. Does this mean the script is executing all the way through?

  • Make JFace Window blink in taskbar or get users attention?

    - by Sophomore
    Hi folks I wonder someone has any idea how to solve this: In my Java Eclipse plugin there are some processes which take some time. Therefore the user might minimize the window and let the process run in the background. Now, when the process is finished, I can force the window to come to the top again, but that is a no-no in usability. I'd rather want the process to blink in the taskbar instead. Is there any way to achieve this? I had a look at the org.eclipse.jface.window but could'nt find anything like that, same goes for the SWT documentation... Another thing which came to my mind - as people are using this app on mac os x and linux as well, is there a platform independant solution, which will inform the user that the process has finished but without bringing the window to the top? Any ideas are highly welcome! Edit: I found out that on windows the user can adjust whether he would like to enable a force to foreground or not. If that option is disabled, the task will just blink in the taskbar... Here's a good read on that... If anyone maybe knows about some platform independant way of achieving this kind of behaviour, please share your knowledge with me!

  • Excel 2010 64 bit can't create .net object

    - by aboes81
    I have a simple class library that I use in Excel. Here is a simplification of my class... using System; using System.Runtime.InteropServices; namespace SimpleLibrary { [ComVisible(true)] public interface ISixGenerator { int Six(); } public class SixGenerator : ISixGenerator { public int Six() { return 6; } } } In Excel 2007 I would create a macro enabled workbook and add a module with the following code: Public Function GetSix() Dim lib As SimpleLibrary.SixGenerator lib = New SimpleLibrary.SixGenerator Six = lib.Six End Function Then in Excel I could call the function GetSix() and it would return six. This no longer works in Excel 2010 64bit. I get a Run-time error '429': ActiveX component can't create object. I tried changing the platform target to x64 instead of Any CPU but then my code wouldn't compile unless I unchecked the Register for COM interop option, doing so makes it so my macro enable workbook cannot see SimpleLibrary.dll as it is no longer regsitered. Any ideas how I can use my library with Excel 2010 64 bit?

  • What's the order of execution in property setters when using IDataErrorInfo?

    - by Benny Jobigan
    Situation: Many times with WPF, we use INotifyPropertyChanged and IDataErrorInfo to enable binding and validation on our data objects. I've got a lot of properties that look like this: public SomeObject SomeData { get { return _SomeData; } set { _SomeData = value; OnPropertyChanged("SomeData"); } } Of course, I have an appropriate overridden IDataErrorInfo.this[] in my class to do validation. Question: In a binding situation, when does the validation code get executed? When is the property set? When is the setter code executed? What if the validation fails? For example: User enters new data. Binding writes data to property. Property set method is executed. Binding checks this[] for validation. If the data is invalid, the binding sets the property back to the old value. Property set method is executed again. This is important if you are adding "hooks" into the set method, like: public string PathToFile { get { return _PathToFile; } set { if (_PathToFile != value && // prevent unnecessary actions OnPathToFileChanging(value)) // allow subclasses to do something or stop the setter { _PathToFile = value; OnPathToFileChanged(); // allow subclasses to do something afterwards OnPropertyChanged("PathToFile"); } } }

  • DotNetNuke and Subversion guidelines

    - by David Stratton
    I've Googled, Binged, and here at StackOverflow, looked through the related questions and searched, but I'm not finding what I'm looking for. I've also searched documentation on DNN. What I'm looking for is any guidance (tutorials, blogs, step-by-step instructions for setting up a repository) etc from people who are experienced in using DotNetNuke with SVN. We use SVN for all our source control, and have no problem with standard applications, because we pretty much built the repository and directory structure to work with our processes. This means when we do web sites, in Visual Studio, we do file based web sites, rather than setting them up in the local IIS. It just makes things easier for us. However, with DNN, it appears that even if you get the source code, it is expecting to be set up in the local IIS, which means additional headaches for us. For example, we are moving all of our source code off our local C drives, and onto a shared drive on a server. This is to enable backups in addition to our normal source control. (This was a management decision). So that means that we need to change the virtual web app when we make the move. Has anyone come up with a good way to work around this? Can DNN be set up so that the developer web server in Visual Studio can be used, so that we can treat it just like any normal web app? Am I missing something obvious? Edit - added I'm willing to accept answers like "We tried it and never got it to work", and "It can't be done" as answers. I'm always open to hearing "It can't be done the way you want. You need to change your procedures to match how it works" if necessary. I guess if you've got experience trying this and just couldn't get it to work, I can learn from your experience that way as well, but some detail would be good.

  • jQuery: bind generated elements

    - by superUntitled
    Hello, thank you for taking time to look at this. I am trying to code my very first jQuery plugin and have run into my first problem. The plugin is called like this <div id="kneel"></div> <script type="text/javascript"> $("#kneel").zod(1, { }); </script> It takes the first option (integer), and returns html content that is dynamically generated by php. The content that is generated needs to be bound by a variety of functions (such as disabling form buttons and click events that return ajax data. The plugin looks like this (I have included the whole plugin in case that matters)... (function( $ ){ $.fn.zod = function(id, options ) { var settings = { 'next_button_text': 'Next', 'submit_button_text': 'Submit' }; return this.each(function() { if ( options ) { $.extend( settings, options ); } // variables var obj = $(this); /* these functions contain html elements that are generated by the get() function below */ // disable some buttons $('div.bario').children('.button').attr('disabled', true); // once an option is selected, enable the button $('input[type="radio"]').live('click', function(e) { $('div.bario').children('.button').attr('disabled', false); }) // when a button is clicked, return some data $('.button').bind('click', function(e) { e.preventDefault(); $.getJSON('/returnSomeData.php, function(data) { $('.text').html('<p>Hello: ' + data + '</p>'); }); // generate content, this is the content that needs binding... $.get('http://example.com/script.php?id='+id, function(data) { $(obj).html(data); }); }); }; })( jQuery ); The problem I am having is that the functions created to run on generated content are not binding to the generated content. How do I bind the content created by the get() function?

  • XML-RPC over SSL with Ruby: end of file reached (EOFError)

    - by Michael Conigliaro
    Hello, I have some very simple Ruby code that is attempting to do XML-RPC over SSL: require 'xmlrpc/client' require 'pp' server = XMLRPC::Client.new2("https://%s:%d/" % [ 'api.ultradns.net', 8755 ]) pp server.call2('UDNS_OpenConnection', 'sponsor', 'username', 'password') The problem is that it always results in the following EOFError exception: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/net/protocol.rb:135:in `sysread': end of file reached (EOFError) So it appears that after doing the POST, I don't get anything back. Interestingly, this is the behavior I would expect if I tried to make an HTTP connection on the HTTPS port (or visa versa), and I actually do get the same exact exception if I change the protocol. Everything I've looked at indicates that using "https://" in the URL is enough to enable SSL, but I'm starting wonder if I've missed something. Note that Even though the credentials I'm using in the RPC are made up, I'm expecting to at least get back an XML error page (similar to if you access https://api.ultradns.net:8755/ with a web browser). I've tried running this code on OSX and Linux with the exact same result, so I have to conclude that I'm just doing something wrong here. Does anyone have any examples of doing XML-RPC over SSL with Ruby?

  • Apache proxy to Lighttpd: changing $_SERVER['HTTP_HOST'] in php

    - by watain
    I have a WordPress blog running on lighttpd-1.4.19, listening on at www00:81. On the same host, apache-2.2.11 listens on port 80, which creates a proxy connection from http://blog.mydomain.org:80 to http://blog.mydomain.org:81. The Apache virtualhost looks as follows: <VirtualHost *:80> ServerName blog.mydomain.org ProxyRequests Off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://blog.mydomain.org:81/ ProxyPassReverse / http://blog.mydomain.org:81/ </VirtualHost> Using debug.log-request-handling = "enable" I get the following log entry when I browse http://blog.mydomain.org:80 (notice the Host headers): 2010-05-10 08:47:14: (request.c.294) fd: 6 request-len: 853 GET / HTTP/1.1 Host: blog.mydomain.org:81 [...] 2010-05-10 08:47:15: (request.c.294) fd: 8 request-len: 754 GET /wp-content/uploads/2010/01/image.gif?w=280 HTTP/1.1 Host: www00:81 My problem: as far as I know, the PHP environment variable $_SERVER['HTTP_HOST'] is set to that Host header variable. Unfortunately, WordPress uses that variable in their system to create URLs to pictures on the blog. These URLs won't be accessible behind a firewall of course. How can I force the host header to be blog.mydomain.org instead of blog.mydomain.org:81, respectively www00:81? I already added set server.name = "blog.mydomain.org" to my lighttpd.conf, but this didn't work. Any suggestions are appreciated, thank you.

Anyone out there have any ideas on what could be causing these issues? Edit Tried both suggestions below several months ago to no avail. This issue hasn't arisen since, maybe something out of my control has changed....

  • Why do I get "mysql_query(): supplied argument is not a valid"

    - by Brian Ojeda
    Why do I get a "mysql_query(): supplied argument is not a valid" for the first... $r = mysql_query($q, $connection); In the following code... $bId = trim($_POST['bId']); $title = trim($_POST['title']); $story = trim($_POST['story']); $q = "SELECT * "; $q .= "FROM " . DB_NAME . ".`blog` "; $q .= "WHERE `blog`.`id` = {$bId}"; $r = mysql_query($q, $connection); //confirm_query($r); if (mysql_num_rows($r) == 1) { $q = "UPDATE " . DB_NAME . ".`blog` SET `title` = '{$title}', `story` = '{$story}' WHERE `id` = {$bId}"; $r = mysql_query($q, $connection); if (mysql_affected_rows() == 1) { //Successful $data['success'] = true; $date['errors'] = false; $date['message'] = "You are the Greatest!"; } else { //Fail $data['success'] = false; $data['error'] = true; $date['message'] = "You can't do it fool!"; } } I also get an "mysql_num_rows(): supplied argument is not a valid MySQL result resource" error too. Side notes: I am using 1&1 Hosting (worst hosting ever), custom .htaccess file with one line text to enable PHP 5.2 (only why with 1&1 Hosting).

  • Post complex types to WebApi Client

    - by BumbleBee
    I am new to WebAPI. I have a MVC project and webApi project both reside under the **same solution**. Also, BLL Class library and DAL class library reside under the same solution. Earlier, my MVC project will talk to the BLL now I am trying to create a WebAPi project which stands in between MVC and BLL. Here is what I have come up with so far : I'm using the HTTPClient to post to a WebApi project. My post method on my controller accepts a single parameter (a model). StatsCriteria criteria = new StatsCriteria(); ...... var client = new HttpClient(); var response = client.PostAsJsonAsync("http://localhost:52765/api/reports", criteria).Result; ....... Here's the signature for my controller in Webapi [HttpPost] public CMAReportVM Reports([FromBody] StatsCriteria criteria) { var cmaReport = Service3.GetCMAReport(criteria.Mlsnums); //Create Map to enable mapping business object to View Model Mapper.CreateMap<CMAReport, CMAReportVM>(); // Maps model to VM model class var cmaVM = Mapper.Map<CMAReport, CMAReportVM>(cmaReport); reutn cmaVM; } // and here's my routing: config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } I am getting the following 405 : Method not allowed. As the WebAPI and MVC project both reside under same sloution I am not sure where/how to host my webapi.

  • pdf external streams in Max OS X Preview

    - by olpa
    According to the specification, a part of a PDF document can reside in an external file. An example for an image: 2 0 obj << /Type /XObject /Subtype /Image /Width 117 /Height 117 /BitsPerComponent 8 /Length 0 /ColorSpace /DeviceRGB /FFilter /DCTDecode /F (pinguine.jpg) >> stream endstream endobj I found that this functionality does work in Adobe Acrobat 5.0 for Windows (sample PDF with the image), also I managed to view this file in Adobe Acrobat Reader 8.1.3 for Mac OS X after I found the setting "Allow external content". Unfortunately, it seems that non-Adobe tools ignore the external stream feature. I hope I'm wrong, therefore ask the question: How to enable external streams in Mac OS X? (I think that all the system Mac OS X tools use the same library, therefore say "Mac OS X" instead of "Preview".) Or maybe there could be a programming hook to emulate external streams? My task is: store a big set of images (total ˜300Mb) outside of a small PDF (˜1Mb). At some moment, I want to filter PDF through a quartz filter and get a PDF with the images embedded. Any suggestions are welcome.
