• Grub2 fails to chainload Windows 7 with error "invalid signature"

  - by atomicpirate

  I've built a new UEFI 64-bit system with both Windows 7 and Ubuntu 11.10 installed (on separate hard drives). I'd like to be able to boot Windows 7 from the grub menu, but I have so far been unsuccessful in getting grub to chainload it. After getting the grub menu, I choose the option for the command line and I can see that bootmgfw.efi is at (hd1,gpt1)/efi/Microsoft/Boot/bootmgfw.efi. However, when I attempt to chainload I get an error: grub> chainloader (hd1,gpt1)/efi/Microsoft/Boot/bootmgfw.efi error: invalid signature I am not sure whether I chose the UEFI boot option when I installed Linux from the LiveCD, and so I am wondering if the grub I have is perhaps unable to chainload in this manner? In any case I am not sure how to get the chainload to work.

• Getting error detail from WCF REST

  - by Keith

  I have a REST service consumed by a .Net WCF client. When an error is encountered the REST service returns an HTTP 400 Bad Request with the response body containing JSON serialised details. If I execute the request using Fiddler, Javascript or directly from C# I can easily access the response body when an error occurs. However, I'm using a WCF ChannelFactory with 6 quite complex interfaces. The exception thrown by this proxy is always a ProtocolException, with no useful details. Is there any way to get the response body when I get this error? Update I realise that there are a load of different ways to do this using .Net and that there are other ways to get the error response. They're useful to know but don't answer this question. The REST services we're using will change and when they do the complex interfaces get updated. Using the ChannelFactory with the new interfaces means that we'll get compile time (rather than run time) exceptions and make these a lot easier to maintain and update the code. Is there any way to get the response body for an error HTTP status when using WCF Channels?

• Display nice error message when there is something wrong after ajax request jqgrid

  - by Niels Ilmer

  Hello, I delete rows with this function: function deleteRow(){ rows = jQuery("#category_grid").getGridParam('selarrrow'); if( rows.length>0){ jQuery('#category_grid').delGridRow(rows,{ msg:'Verwijderen geselecteerde rijen?' }); }else{ alert("Selecteer eerst een rij om te verwijderen!"); } } but when it's fails in my php, server side and a exception is thrown. The errormessage looks not nice. How can i show errotext in the dialog box? or catch an error message after an ajax call? At the moment the error message looks like: error Status: 'CDbException'. Error code: 500 When i googled i found a event of the delGridRow function called errorTextFormat. Is this the event where i'm looking for? Can someone please give me an example of the implementation of this event? greetings niels

• Exchange 2007 to 2010 public folder replication error 1129

  - by Keith

  I currently upgrading from an Exchange server 2007 to 2010. I have moved all mailboxes and OAB. I am having issues replicating the public folders. This is the error I'm getting in the event log on the 2007 box: Error 1129 occurred while processing a replication event. Folder: (6-11ED8367F0C) IPM_SUBTREE\Marketing\Marketing I have looked online and everything about these errors seems to relate from an old 2003 server. Well, we never had a 2003 server. I'm really not sure what to do at this point. Any help?

• Why does Http Web Request and IWebProxy work at wierd times

  - by Mike Webb

  Another question about Web proxy. Here is my code: IWebProxy Proxya = System.Net.WebRequest.GetSystemWebProxy(); Proxya.Credentials = CredentialCache.DefaultNetworkCredentials; HttpWebRequest rqst = (HttpWebRequest)WebRequest.Create(targetServer); rqst.Proxy = Proxya; rqst.Timeout = 5000; try { rqst.GetResponse(); } catch(WebException wex) { connectErrMsg = wex.Message; proxyworks = false; } This code fails the first time it is called. After that on successive calls it works sometimes, but not others. It also never hits the catch block. Now the weird part. If I add a MessageBox.Show(msg) call in the first section of code before the GetResponse() call this all will work every time. Here is an example: try { // ========Here is where I make the call and get the response======== System.Windows.Forms.MessageBox.Show("Getting Response"); // ========This makes the whole thing work every time======== rqst.GetResponse(); } catch(WebException wex) { connectErrMsg = wex.Message; proxyworks = false; } I'm baffled about why it is behaving this way. I don't know if the timeout is not working (it's in milliseconds, not seconds, so should timeout after 5 seconds, right?...) or what is going on. The most confusing this is that the message box call makes it all work. So any help and suggestions on what is happening is appreciated. These are the kind of bugs that drive me absolutely out of my mind.

• simple document server built over Apache HTTP server

  - by abhinav

  Hi, I want to build a simple document server. The requirement for now is : provide a hierarchical directory structure for placing documents (like pdfs, doc files) that is accessible through a browser, and provide the facility to search for documents by name and then be able to download them from server. Right now, placing documents can be done manually (directly place the files into some designated directory). I can do the hierarchical structure part of the problem by adding some configs to Apache's httpd.conf file. Basically I create a root directory for documents and then give an alias to this directory in httpd.conf file. That way, I can browse the directory structure in my browser and also download files placed there. I can provide more detail on this if needed. However, it is the searching documents by name part that I am not able to get to a clear solution yet. I have a few ideas like integrating Lucene with Apache server, or maybe using CouchDb, but I am not very sure of all the details to solve this problem. Could anyone suggest some clear approach as to how to solve this part ?

• Getting a 404 when setting up MVC in IIS 6 and using .NET 4 beta 2

  - by joshcomley

  Hi all, I've completed this set up on a fair few IIS 6 boxes, but one is giving me a tough time. The problem occurs when I add the application extension mapping to: c:\windows\microsoft.net\framework\v4.0.21006\aspnet_isapi.dll When this is in place, I get a 404 error on every request. Even if I remove all files from the application directory apart from a basic test.htm and navigate to that, I still get a 404. I've unchecked the "Verify that file exists" I've set up a .NET 4 application pool and pointed my application to that I've changed the ASP.NET version to 4.0.21006 I've checked the IIS log file, and there's nothing useful in there (it only shows the first bunch of requests after each reboot and then stops logging) I've checked the application event log and nothing gets reported I've installed MVC 2 I've copied the set up onto another box, just to be sure, following all the same steps - and it all works! What else can I look out for?? N.B: If I set .NET to v2 in IIS, then I can successfully navigate to \test.htm

• How do you fix TSD02016 error in Database

  - by Keith Sirmons

  Howdy, I have a database I am using the Visual Studio 2010 Database Project tool vsdbcmd.exe to create a schema from. vsdbcmd /a:Import /dsp:Sql /model:"Database" /cs:"Server=SqlServer; Initial Catalog=DatabaseName; Integrated Security=SSPI;" The tool is reporting an error: Error TSD02016, Gen-259 (12,50) The column name is not valid. No table name was specified. How would I go about pinpointing where this error is originating? I have found one resource on the internet (http://social.msdn.microsoft.com....) that points to a possibility of a keyword used incorrectly, but the error messages are not the same. What is Gen-259? Thank you, Keith

• Use HttpGet with illegal characters in the URL

  - by kaciula

  I am trying to use DefaultHttpClient and HttpGet to make a request to a web service. Unfortunately the web service URL contains illegal characters such as { (ex: domain.com/service/{username}). It's obvious that the web service naming isn't well written but I can't change it. When I do HttpGet(url), I get that I have an illegal character in the url (that is { and }). If I encode the URL before that, there is no error but the request goes to a different URL where there is nothing. The url, although has illegal characters, works from the browser but the HttpGet implementation doesn't let me use it. What should I do or use instead to avoid this problem?

• Bluescreen 0x0000003B during DownloadFileAsync?

  - by SeveQ

  Hello again, I've run into a problem with an application I'm developing in C#/.NET. A problem I can't trace down because it causes my system to crash with a BSOD. Here's the minidump: 060310-27066-01.dmp 03.06.2010 19:47:39 SYSTEM_SERVICE_EXCEPTION 0x0000003b 00000000c0000005 fffff8000306d4d0 fffff8800b107640 0000000000000000 ntoskrnl.exe ntoskrnl.exe+70600 NT Kernel & System Microsoft® Windows® Operating System Microsoft Corporation 6.1.7600.16539 (win7_gdr.100226-1909) x64 C:\Windows\Minidump\060310-27066-01.dmp 4 15 7600 It's not related specifically to DownloadFileAsync. Other methods of the System.Net assembly classes related to HTTP download also make my system crash. I really hope someone can help me with this. Just for info: other apps (browsers etc.) that download files work like a charm. If you need further information don't hesitate to ask! Thanks!

• "Error loading operating system": Win7/Vista

  - by LookitsPuck

  Have this computer for about 2 years now. Originally had Vista installed, now have Windows 7 installed. Both on separate hard drives. Also have another drive used strictly for media. About a week ago, the Vista hard drive started going on its way out. Was getting problems on startup. After a few BIOS settings, I was able to get into Windows 7 and everything was fine. However, I started remembering the startup issues, so I deleted the bootup for Vista under msconfig. Didn't restart the computer at that time, though. For a few days, everything was ok. Last night I play a little poker, then hit the hay. I wake up to a good ole "Error loading operating system" on the screen. Just wonderful. Looks like the computer restarted overnight (auto updates, anyone?). So, after a big of finagling and half hearted tries, I can't get past the "Error loading operating system" screen. FWIW, in the BIOS it can see my hard drives fine. So I move on. I get my Windows 7 installation disk to try and do a repair. Go in the BIOS, change boot priority to DVD drive, and we're on our merry way. After loading from the disc, I first try jumping into the "Repair your computer" section. That opens up the System Recovery Options. However, this is where the problem comes into play. I don't see any operating systems here. Nada. What's odd though is if I click on the Load Drivers button, I can see my Windows 7 partition (C:), and can go through the files and folders without issue. What do I do at this point? I can't repair it. It seems like I can traverse the hard drive without issue when in an open dialog in the System Recovery Options, but I'm getting the good ole "Error loading computer" on bootup. Suggestions? Thanks all!!

• Need assistance with Kohana 3 and catch all route turning into a 404 error

  - by alex

  Based on this documentation, I've implemented a catch all route which routes to an error page. Here is the last route in my bootstrap.php Route::set('default', '<path>', array('path' => '.+')) ->defaults(array( 'controller' => 'errors', 'action' => '404', )); However I keep getting this exception thrown when I try and go to a non existent page Kohana_Exception [ 0 ]: Required route parameter not passed: path If I make the <path> segment optional (i.e. wrap it in parenthesis) then it just seems to load the home route, which is... Route::set('home', '') ->defaults(array( 'controller' => 'home', 'action' => 'index', )); The home route is defined first. I execute my main request like so $request = Request::instance(); try { // Attempt to execute the response $request->execute(); } catch (Exception $e) { if (Kohana::$environment === Kohana::DEVELOPMENT) throw $e; // Log the error Kohana::$log->add(Kohana::ERROR, Kohana::exception_text($e)); // Create a 404 response $request->status = 404; $request->response = Request::factory(Route::get('default')->uri())->execute(); } $request->send_headers(); echo $request->response; This means that the 404 header is sent to the browser, but I assumed by sending the request to the capture all route then it should show the 404 error set up in my errors controller. <?php defined('SYSPATH') or die('No direct script access.'); class Controller_Errors extends Controller_Base { public function before() { parent::before(); } public function action_404() { $this->bodyClass[] = '404'; $this->internalView = View::factory('internal/not_found'); $longTitle = 'Page Not Found'; $this->titlePrefix = $longTitle; } } Why won't it show my 404 error page?

• Error using ASP.NET 3.5 Chart control within a Repeater control

  - by tuseau

  Hi, I'm getting the error "Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Error executing child request for ChartImg.axd" at runtime from my Chart control. I have read one solution to this error message as documented here: http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/thread/1dc4b352-c9a5-49dc-8f35-9b176509faa1/ but this does not solve my problem. I have the Chart within a Repeater control, which is within an ajax UpdatePanel. When I take the chart out of the Repeater (but leave it in the UpdatePanel), it works. So I'm thinking it is to do with the Repeater. Anyone got any ideas? Thanks in advance.

• Ajax Get Request works fine when requested in browser, but gets 302 in iframe. What could be the reason for this?

  I am working on a web app that makes several ajax requests at startup. The applications works fine when run individually. When running it into a iframe, one of the ajax requests returns a 302 Found HTTP status. I'm sure I'm hitting the same url with both the browser and the iframe. The application that creates the frame is on a different domain and port. What could be causing this? Out of 5 get requests to the same server, only one (the third) gets a 302.
