  • Disable page cache on a specific page

    - by David Brunelle
    Hi, Not sure if I really am on the right forum, but if not, just tell me. I have a page that is coded in ASP (not .net) which is used to send email. We are currently having a problem in which the page seem to be sent twice sometime. Upon checking, we found out that those who have this problem are coming from big organisation, so it was suggested that their server might cache the file for some reason. I would like to know, is there a way in HTML (or ASP ) to prevent that from happening ? Or is it in IIS that we must set this up ? Thanks,

  • Problem identifying which page/page/function locks whole IIS server

    - by fnovak
    Hello, I have problem identifying which page/page/function locks whole IIS server. Out of the blue whole w3wp.exe jumps to CPU 90-98% usage. I have created 3 different application pools to see which w3wp.exe service locks the processor but I am unable to find out this information. I can only see that 2 of 3 services have 0-5% usage and one is jumping around 90-98% after some while. I think some process/function/redirect/sql is doing this but I would like to eliminate it. So far I am not even able to find the source of the problem. On my local development machine with VS2010 everything works like charm and I am unable to replicate problem. The server is windows 2k3 web server, sql server 2k5 and .net 4.0 Thank you for your help, links or any information on this issue. Fero

  • htaccess redirect from wordpress page to a php page

    - by JustAnil
    I have recently had to change a URL on a website (in PHP on Apache). The old URL is: http://content.mywebsite.org.uk/hidden/discounts/ When a user visits the above link. The new URL is: http://www.mywebsite.org.uk/charity_benefits.php I have tried variants of the following (and some others), but its just not working for me. RewriteCond %{REQUEST_URI} ^/hidden/discounts/$ [NC] RewriteRule ^/hidden/discounts/$ /charity_benefits.php [R=302,L,NC] I need the redirect to redirect to www mywebsite.org.uk. (Notice the www! Its important!). So basically, a simple redirect from the old page to the new page. (Which are on different subdomains (OLD: content., NEW: www.) which are hosted on the same server).

  • Large number of soft page faults when assigning a TJpegImage to a TBitmap

    - by Robert Oschler
    I have a Delphi 6 Pro application that processes incoming jpeg frames from a streaming video server. The code works but I recently noticed that it generates a huge number of soft page faults over time. After doing some investigation, the page faults appear to be coming from one particular graphics operation. Note, the uncompressed bitmaps in question are 320 x 240 or about 300 KB in size so it's not due to the handling of large images. The number of page faults being generated isn't tolerable. Over an hour it can easily top 1000000 page faults. I created a stripped down test case that executes the code I have included below on a timer, 10 times a second. The page faults appear to happen when I try to assign the TJpegImage to a TBitmap in the GetBitmap() method. I know this because I commented out that line and the page faults do not occur. The assign() triggers a decompression operation on the part of TJpegImage as it pushes the decompressed bits into a newly created bitmap that GetBitmap() returns. When I run Microsoft's pfmon utility (page fault monitor), I get a huge number of soft page fault error lines concerning RtlFillMemoryUlong, so it appears to happen during a memory buffer fill operation. One puzzling note. The summary part of pfmon's report where it shows which DLL caused what page fault does not show any DLL names in the far left column. I tried this on another system and it happens there too. Can anyone suggest a fix or a workaround? Here's the code. Note, IReceiveBufferForClientSocket is a simple class object that holds bytes in an accumulating buffer. function GetBitmap(theJpegImage: TJpegImage): Graphics.TBitmap; begin Result := TBitmap.Create; Result.Assign(theJpegImage); end; // --------------------------------------------------------------- procedure processJpegFrame(intfReceiveBuffer: IReceiveBufferForClientSocket); var theBitmap: TBitmap; theJpegStream, theBitmapStream: TMemoryStream; theJpegImage: TJpegImage; begin theBitmap := nil; theJpegImage := TJPEGImage.Create; theJpegStream:= TMemoryStream.Create; theBitmapStream := TMemoryStream.Create; try // 2 // ************************ BEGIN JPEG FRAME PROCESSING // Load the JPEG image from the receive buffer. theJpegStream.Size := intfReceiveBuffer.numBytesInBuffer; Move(intfReceiveBuffer.bufPtr^, theJpegStream.Memory^, intfReceiveBuffer.numBytesInBuffer); theJpegImage.LoadFromStream(theJpegStream); // Convert to bitmap. theBitmap := GetBitmap(theJpegImage); finally // Free memory objects. if Assigned(theBitmap) then theBitmap.Free; if Assigned(theJpegImage) then theJpegImage.Free; if Assigned(theBitmapStream) then theBitmapStream.Free; if Assigned(theJpegStream) then theJpegStream.Free; end; // try() end; // --------------------------------------------------------------- procedure TForm1.Timer1Timer(Sender: TObject); begin processJpegFrame(FIntfReceiveBufferForClientSocket); end; // --------------------------------------------------------------- procedure TForm1.FormCreate(Sender: TObject); var S: string; begin FIntfReceiveBufferForClientSocket := TReceiveBufferForClientSocket.Create(1000000); S := loadStringFromFile('c:\test.jpg'); FIntfReceiveBufferForClientSocket.assign(S); end; // --------------------------------------------------------------- Thanks, Robert

  • Problems with MediaPlayer, raw resources, stop and start

    - by arakn0
    Hello everybody, I'm new in Android development and I have the next question/problem. I'm playing around with the MediaPlayer class to reproduce some sounds/music. I am playing raw resources (res/raw) and it looks kind of easy. To play a raw resource, the MediaPlayer has to be initialized like this: MediaPlayer mp = MediaPlayer.create(appContext, R.raw.song); mp.start(); Until here there is no problem. The sound is played, and everything works fine. My problem appears when I want to add more options to my application. Specifically when I add the "Stop" button/option. Basically, what I want to do is...when I press "Stop", the music stops. And when I press "Start", the song/sound starts over. (pretty basic!) To stop the media player, you only have to call stop(). But to play the sound again, the media player has to be reseted and prepared. mp.reset(); mp.setDataSource(params); mp.prepare(); The problem is that the method setDataSource() only accepts as params a file path, Content Provider URI, streaming media URL path, or File Descriptor. So, since this method doesn't accept a resource identifier, I don't know how to set the data source in order to call prepare(). In addition, I don't understand why you can't use a Resouce identifier to set the data source, but you can use a resource identifier when initializing the MediaPlayer. I guess that I'm missing something. I wonder if I am mixing concepts, and the method stop() doesn't have to be called in the "Stop" button. Any help? Thanks in advanced!!!

  • .NET 4: Process.Start using credentials returns empty output

    - by alexey
    I run an external program from ASP.NET: var process = new Process(); var startInfo = process.StartInfo; startInfo.FileName = filePath; startInfo.Arguments = arguments; startInfo.UseShellExecute = false; startInfo.RedirectStandardOutput = true; startInfo.RedirectStandardError = true; process.Start(); process.WaitForExit(); Console.Write("Output: {0}", process.StandardOutput.ReadToEnd()); Console.Write("Error Output: {0}", process.StandardError.ReadToEnd()); Everything works fine with this code: the external program is executed and process.StandardOutput.ReadToEnd() returns the correct output. But after I add these two lines before process.Start() (to run the program in the context of another user account): startInfo.UserName = userName; startInfo.Password = securePassword; The program is not executed and process.StandardOutput.ReadToEnd() returns an empty string. No exceptions are thrown. userName and securePassword are correct (in case of incorrect credentials an exception is thrown). How to run the program in the context of another user account?

  • Slow Execution of an ASP.NET Web Page

    - by Sweta Jha
    I have a web page which brings 13K+ records in 20 seconds. There is a menu on the page, clicking on which navigates me to another page which is very lightweight. Displaying the data (13K+) took only 20 seconds whereas navigating from that page took much longer, more than 2 mins. Can you tell me why is the latter taking so much of time. I've stopped the page_load code execution on click of the menu. I've disabled the viewstate for that page as well.

  • jQuery UI Dialog cause page jump on open & close on ASP.NET

    - by Gal V
    Hello all, I have an ASP.NET C# page, with image thumbnails in it. I created a script that opens a jQuery UI Dialog on each hover on a thumbnail that shows me the thumbnail in larger size in a dialog view, and when I hover out - dialog closes. My little annoying problem is, that in every mouseover (trigger dialog to open) - the page makes itself 'longer' - a scrollbar appears on the side of the browser, and it seems like the page gets longer when a dialog is openning, but it shouldn't do so. When I hover off (mouseout) - the dialog disappears and the page returns to its normal state. Because of this- when I hover through the thumbnails, my page 'jumps'. I looked for a solution for this, and I've added return false; for each dialog open, and close - and it still doesn't make any different. Sorry for the unperfect english, and thanks for all helpers!

  • Google Website Optimizer - Multi Variant Testing - Make a specific page a test page for two experime

    - by wawawowo
    Im having a little issue with setting up Multi Variant Tests in Google Website Optimizer. I wish to have two tests. One being which is a header banner which appears on every page and the conversion for example would be if the visitor lands on the contact us page. This was very easy to set up. However when I intend to add another test, again this will be on a element which appears on every page and the conversion page is if the visitor lands on the checkout page. But I am now having problems installing the control script. I get the error: Expected to find: }(function(){var k='0651116117',d=docum Found on line 7: (function(){var k='2666211118',d=docum Im assuming I have this error because I now have two control scripts in the header - one for each experiment. However I cannot combine each variation into just one experiment because each one is different and has a different conversion page? Please advise, thanks.

  • Empty page instead of custom tomcat error page

    - by Alexander
    My setting: Apache 2.2 + Tomcat 6.0 @ Windows 2008 R2 64bit static webpages: / servlet: /foo tomcat and apache are connected by mod_jk 404.jsp is placed in tomcat\webapps\ROOT tomcat\conf\web.xml: <error-page> <error-code>404</error-code> <location>/404.jsp</location> </error-page> apache\conf\extra\httpd-ssl.conf: JkMount /foo/* worker1 JkMount /404.jsp worker1 When I open https://...../404.jsp my custom error page is displayed.

For each control I created a validation group, then I tried to use the code below, the problem is, it will always return a false value eventhough the page validation has been satisfied.What went wong with the code below?By the way I used Ajax in my application. if (typeof (Page_Validators) != "undefined") { if (typeof (Page_ClientValidate) == 'function') { Page_ClientValidate(); } if (Page_IsValid) { // do something alert('Page is valid!'); } else { // it will always goes here eventhough it was validated successfully alert('Page is not valid!'); } }

  • Switching layouts page jumping (improvement to script)

    - by Ricardo Zea
    Hello, I'm using this script to switch layouts in a page: $("span.switcher").click(function () { $("span.switcher").toggleClass("swap"); /*!*/ $("ol.search-results").fadeOut("fast", function() { $(this).fadeIn("fast").toggleClass("grid"); }); The script works fine, the problem I have is that if the switch view is down the page, the layout changes and then the page jumps back up. If I add 'return false' right where you see the /* ! */ in the second line the script doesn't work. Also, as you can see, I'm using < span instead of < a since I was told that using other element other than < a would stop the page from jumping. Any idea how to fix the jumping of the page? Thanks.

  • start /B doesn't start the task

    - by Fractaliste
    I'm currently launching an asynchronous job with PHP to perform some tests. To make it work, I found on SO some tips, like the use of popen and start: $commande = "testu.bat"; $pid = popen('start /B ' . $commande, 'r'); $status = pclose($pid); The testu.bat's folder is in my user PATH. This script performs some task, and to control it's execution, it should generates a log file, but I never get it. Whereas if I just remove the /B option, it works fine and I get my log file. Did I miss something about background execution? How can I catch the error informations when it is running in the background?

  • Using rel=next and rel=prev with multiple sets of paginated content on the same page

    - by jakejgordon
    We are running into issues with trying to figure out how to implement rel="next" and rel="prev" -- coupled with rel="canonical" -- with multiple sets of paginated content on the same page, with pages in multiple cultures. In other words, how do we implement these when we have a pager for both Product Reviews and Questions and Answers (aka "Q&A") on the same page, with duplicate content across culture-specific URLs (e.g. /us/en/my-product vs. /ca/en/my-product)? Our current implementation will actually do a full postback when you click Page 2, and will add something to the query string (e.g. website.com/ca/en/my-product?previewpage=2 or website.com/ca/en/my-product?questionpage=2). If we only had one set of paginated content then the implementation would certainly be more straightforward. Adding a second set of paginated content (i.e. Q&A) complicates things. Let's assume that we want the United States English page to be the canonical target (i.e. /us/en/my-product) based on culture. If you go to the /ca/en/my-product page you'll have a rel="canonical" href="/us/en/my-product". So far so good. Let's also assume that we are not implementing a page that lists ALL Product Reviews and Q&A. This would likely solve a number of our problems by using rel="canonical" to this page, but is not an option for reasons that are out of scope for this discussion. Now if you click on page 2 of Product Reviews, it will reload the page with /ca/en/my-product?reviewpage=2 as the URL. Given this scenario, here are my questions: On page 2 of the my-product page on the Canadian site, should there be a rel="canonical" to /us/en/my-product?reviewpage=2 (assuming the content is identical in the United States and Canada)? Should the rel="prev" go to /ca/en/my-product?reviewpage=1 or should it go to /ca/en/my-product ? The query-string version would really only be accessible if using the pager and shows the exact same content as the base page. The following two questions are closely related to this one. Should the /ca/en/my-product?reviewpage=1 have a rel canonical directly to /us/en/my-product (United States page with nothing in query string) since the content is identical)? Given that Q&A content is also paginated, should there be a rel="next" on the base page without query string? In other words, should the /ca/en/my-product page have a rel="next" to /ca/en/my-product?reviewpage=2 AND rel="next" to /ca/en/my-product?questionpage=2 . So far as I can tell it doesn't make sense to have multiple rel="next" implementations on the same page. I suspect that the pages with query string values should have rel="next" and rel="prev" that only point to other pages with query strings and not to the base page. The ?reviewpage=1 and ?questionpage=1 pages would then just have a rel="canonical" to /us/en/my-product . Thoughts? I know this is a tough one -- that's why I brought it to this community. Thanks so much for your help in advance!

  • Apache displays error page half way through PHP page execution

    - by Shep
    I've just installed Zend Server Community Edition on a Windows Server 2003 box, however there's a bit of a problem with the display of a lot of our PHP pages. The code has previously running under the same version of PHP (5.3) on IIS without any issues. By the looks of things, Apache (installed as part of Zend Server) is erroring out during the rendering of the page when it comes across something it doesn't like in the PHP. Going through the code, I've been able to get past some of the problems by removing the error suppression operator (@) from function calls and by changing the format of some includes. However, I can't do this for the whole site! Weirdly, the error code is reported as "200 OK". The code snippet below shows how the Apache error HTML interrupts the regular HTML of the page. <p>Ma quande lingues coalesce, li grammatica del resultant lingue es plu simplic e regulari quam ti del coalescent lingues.</<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN"> <html><head> <title>200 OK</title> </head><body> <h1>OK</h1> <p>The server encountered an internal error or misconfiguration and was unable to complete your request.</p> <p>Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.</p> <p>More information about this error may be available in the server error log The Apache error log doesn't offer any explanation for this, and I've exhausted my Googling skills, so any help would be greatly appreciated. Thanks.

  • Problem printing google maps printing and using 'page-break-before' in IE8

    - by murdoch
    Hi, I'm having an annoying problem trying to get an html page with a google map on it to print correctly, I have a google map with an <h2> above it all wrapped in a div and the div is set to 'page-break-before:always;' in the css so that the map and its heading always sits on a new page. The problem is that in IE8 only i can always see a large portion of the map rendered on the previous page when printed, also the part of the map that is visible on the previous page is that which is outside the visible bounds of the map. HTML: <div id="description"> <h2>Description</h2> <p>Some paragraph of text</p> <p>Some paragraph of text</p> <p>Some paragraph of text</p> </div> <div id="map"> <h2>Location</h2> <div id="mapHolder"></div> <script type="text/javascript"> // ... javascript to create the google map </script> </div> CSS: #map { page-break-before:always; } Here is a screen grab of what it renders like in IE8 http://twitpic.com/1vtwrd It works fine in every other browser i have tried including IE7 so i'm a bit lost, has anyone any ideas of any tricks to stop this from happening?

  • WPF Enable/Disabled controls from a page placed inside main window application

    - by toni
    Hi! I have an WPF application that has a main window. In the left side of this Window there are some buttons into a listbox, it is a kind of menu to access faster to pages. These buttons belongs to pages that they are loaded inside the window when the user selects one. Main window also has another main menu in the top for doing other tasks. When a page is loaded in the main window and the user clicks a button of this currently loaded page, it starts a task that takes a long time. While this long task is executing I want the user can not select (or press) any of the buttons into the listbox because In the loaded page the long task also is updating the UI for this page. I would like to disabled (isEnabled=false) the listbox when long task is executing and not to enabled it until the long task has finished. How can I do this? I mean, from the page is currently loaded I want to disabled the listbox placed in the main window that is the owner. The listbox doesn't belong to the currently loaded page. Thanks!
