  • Methodology To Determine Cause Of User Specific Error

    - by user3163629
    We have software that for certain clients fails to download a file. The software is developed in Python and compiled into an Windows Executable. The cause of the error is still unknown but we have established that the client has an active internet connection. We suspect that the cause is due to the clients network setup. This error cannot be replicated in house. What technique or methodology should be applied to this kind of specific error that cannot be replicated in house. The end goal is to determine the cause of this error so we can move onto the solution. For example; Remote Debugging: Produce a debug version of the software and ask the client to send back a debug output file. This involves alot of time (back and forth communication) and requires the client to work and act in a timely manor to be successful. In-house debugging: Visit the client and determine their network setup, etc. Possibly develop a series of script tests before hand to run on the clients computer under the same network. Other methodologies and techniques I am not aware of?

  • Spring + JSR 303 Validation group is ignored [closed]

    - by nsideras
    we have a simple bean with JSR annotations public class CustomerDTO { private static final long serialVersionUID = 1L; private Integer id; @NotEmpty(message = "{customer.firstname.empty}") private String firstName; @NotEmpty(message = "{customer.lastname.empty}") private String lastName; @NotEmpty(groups={PasswordChange.class}, message="{password.empty}") private String password; @NotEmpty(groups={PasswordChange.class}, message="{confirmation.password.empty}") private String password2; } and we have a Spring Controller @RequestMapping(value="/changePassword", method = RequestMethod.POST) public String changePassword(@Validated({ PasswordChange.class }) @ModelAttribute("customerdto") CustomerDTO customerDTO, BindingResult result, Locale locale) { logger.debug("Change Password was submitted with information: " + customerDTO.toString()); try { passwordStrengthPolicy.checkPasswordStrength(locale, customerDTO.getPassword()); if (result.hasErrors()) { return "changePassword"; } logger.debug("Calling customer service changePassword: " + customerDTO); customerOnlineNewService.changePassword(customerDTO); } catch (PasswordNotChangedException e) { logger.error("Could not change password PasswordNotChangedException: " + customerDTO.toString()); return "changePassword"; } catch (PasswordNotSecureException e) { return "changePassword"; } return createRedirectViewPath("changePassword"); } Our problem is that when changePassword is invoked the validator ignores the group(PasswordChange.class) and validates only firstName and lastName which are not in the group. Any idea? Thank you very much for your time.

  • Restrictive routing best practices for Google App Engine with python?

    - by Aleksandr Makov
    Say I have a simple structure: app = webapp2.WSGIApplication([ (r'/', 'pages.login'), (r'/profile', 'pages.profile'), (r'/dashboard', 'pages.dash'), ], debug=True) Basically all pages require authentication except for the login. If visitor tries to reach a restrictive page and he isn't authorized (or lacks privileges) then he gets redirected to the login view. The question is about the routing design. Should I check the auth and ACL privs in each of the modules (pages.profile and pages.dash from example above), or just pass all requests through the single routing mechanism: app = webapp2.WSGIApplication([ (r'/', 'pages.login'), (r'/.+', 'router') ], debug=True) I'm still quite new to the GAE, but my app requires authentication as well as ACL. I'm aware that there's login directive on the server config level, but I don't know how it works and how I can tight it with my ACL logic and what's worse I cannot estimate time needed to get it running. Besides, it looks only to provide only 2 user groups: admin and user. In any case, that's the configuration I use: handlers: - url: /favicon.ico static_files: static/favicon.ico upload: static/favicon.ico - url: /static/* static_dir: static - url: .* script: main.app secure: always Or I miss something here and ACL can be set in the config file? Thanks.

  • Speed up ADF Mobile Deployment to Android with Keystore

    - by Shay Shmeltzer
    As you might have noticed from my latest ADF Mobile entries, I'm doing most of my ADF Mobile development on a windows machine and testing on an Android device. Unfortunately the Android/windows experience is not as fast as the iOS/Mac one. However, there is one thing I learned today that can make this a bit less painful in terms of the speed to deploy and test your application - and this is to use the "Release" mode when deploying your application instead of the "Debug" mode. To do this you'll first need to define a keystore, but as Joe from our Mobile team showed me today, this is quite easy. Here are the steps: Open a command line in your JDK bin directory (I just used the JDK that comes with the JDeveloper install). Issue the following command: keytool –genkey –v –keystore <Keystore Name>.keystore –alias <Alias Name> -keyalg RSA –keysize 2048 –validity 10000 Both keystore name and alias names are strings that you decide on. The keytool utility will then prompt you with various questions that you'll need to answer. Once this is done, the next step is to configure your JDeveloper preferences->ADF Mobile to add this keystore there under the release tab:  Then for your application specific deployment profile - switch the build mode from debug to release. The end result is a much smaller mobile application (for example from 60 to 21mb) and a much faster deployment cycle (for me it is about twice as fast as before).

  • How to handle key in PhP array if the key contains japanese characters [migrated]

    - by Jim Thio
    I have this array: [ID] => ????????-???????????__35.79_139.72 [Email] => [InBuildingAddress] => [Price] => [Street] => [Title] => ???????? ??????????? [Website] => [Zip] => [Rating Star] => 0 [Rating Weight] => 0 [Latitude] => 35.7865334803033 [Longitude] => 139.716800710514 [Building] => [City] => Unknown_Japan [OpeningHour] => [TimeStamp] => 0000-00-00 00:00:00 [CountViews] => 0 Then I do something like this: $output[$info['ID']]=$info; //mess up here $tes=$info['ID']['Title']; Well guess what it messes up. Basically even though the content of an array in PhP can be Japanese. Is this true? What's wrong. The error I got is: Debug Warning: /sdfdsfdf/api/test2.php line 36 - Cannot find element ????????-???????????__35.79_139.72 in variable Debug Warning: /sdfdsfdf/api/test2.php line 36 - main() [function.main]: It is not safe to rely on the system's timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Krasnoyarsk' for '7.0/no DST' instead So many question mark Why is this happening. What's really going on inside PhP? Where can I learn more of such things. Most importantly, what would be the best way to handle this situation. Should I tell PhP to internally always use UTF-8? Does PhP array inherenty cannot use non ascii id?

  • Outlook macro runs through 250 iterations before failing with error [migrated]

    - by Senoculus
    Description: I have an Outlook macro that loops through selected emails in a folder and writes down some info to a .csv file. It works perfectly up until 250 before failing. Here is some of the code: Open strSaveAsFilename For Append As #1 CountVar = 0 For Each objItem In Application.ActiveExplorer.Selection DoEvents If objItem.VotingResponse <> "" Then CountVar = CountVar + 1 Debug.Print " " & CountVar & ". " & objItem.SenderName Print #1, & objItem.SenderName & "," & objItem.VotingResponse Else CountVar = CountVar + 1 Debug.Print " " & CountVar & ". " & "Moving email from: " & Chr(34) & objItem.SenderName & Chr(34) & " to: Special Cases sub-folder" objItem.Move CurrentFolderVar.Folders("Special Cases") End If Next Close #1 Problem After this code runs through 250 emails, the following screenshot pops up: http://i.stack.imgur.com/yt9P8.jpg I've tried adding a "wait" function to give the server a rest so that I'm not querying it so quickly, but I get the same error at the same point.

  • Banshee doesn't like opening websites

    - by Allan
    I have come across two bugs (which will be added to launchpad if it's not resolved here) When I open any of the websites in Banshee Amazon or Miro Guide as soon as the site is finished loading it crashes Banshee. If I play any video local or remote it will show 1 frame maybe 0.5 sec of video then I get a black screen and audio continues in the backgound. Specs & Details I have a Fujitsu Amilo 1718 laptop with 2 gig of ram (original 1 gig) graphics is provided by ATI Radeon Xpress 200M (don't laugh it works with compiz....just) I have a link to the output of banshee --debug Here Don't have time to read? Here are the Highlights [2 Warn 11:52:34.814] Caught an exception - System.ArgumentNullException: Argument cannot be null. then abit later Debug info from gdb: Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Operation not permitted. ================================================================= Got a SIGSEGV while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application. ================================================================= Aborted Not music to my ears as you can expect. The version I am using is 1.9.4 from the daily ppa but these bugs happen in any version of banshee from 1.8.1 and up. So if any one has come across a fix for this problem please share!! additional info Both VLC and Miro work on my system so there isn't a system wide problem with video and I haven't mentioned mono so no trolling it will get voted down.

  • StyleCop Custom Rules

    - by Aligned
    There are several blogs on how to do this (http://scottwhite.blogspot.com/2008/11/creating-custom-stylecop-rules-in-c.html, etc). I’ve found a few useful things to point out: Debugging is difficult, but here are the steps (thanks to Tintin’s answer). “One way: 1) Delete your custom rules 2) Open Visual Studio (for dev), open your custom rule solution 3) Build & Deploy custom rules (a PostBuild action to copy the rules into the StyleCop folder is handy) 4) Open Visual Studio (for test) 5) Use VS (dev) and Attach to process devenv.exe (the test VS instance), set breakpoints in the rules you want to debug 6) Use VS’ (test) and right-click on project, Run StyleCop 7) Debug” ~ it worked once, now I’m having problems getting it to work again ~ I also get the message “Cannot evaluate expression because the code of the current method is optimized.” when I try to look at properties. Looking at the source code of the StyleCop.CSharp.Rules.dll that comes with the install. I used JustDecompile from Telerik. Create one xml file and name it the same as the one cs file (CodingGuildelineRules.cs and CodingGuidelinRules.xml) Deploy: 1. Build in Visual Studio 2. Close Visual Studio (Style cop is running so you can’t override your dll without closing) 3. Copy the dll from the bin to the C: \Program Files (x86)\StyleCop 4.7\ 4. Open the settings file or re-open Visual Studio

  • How can I make my PHP development environment more efficient?

    - by pixel
    I want to start a home-brew pet project in PHP. I've spent some time in my life developing in PHP and I've always felt it was hard to organize the development environment efficiently. In my previous PHP work, I've used a windows desktop machine and a linux server for development. This configuration had it's advantages: it's easy to configure Apache (and it's modules)/PHP/MySql on a linux box, and, at the time, this configuration was the same like on production server. However, I never successfully set up a debug connection between my Eclipse install and X-debug on server. Transferring files from my local workspace to the server was also very annoying (either ftp or Bazaar script moving files from repository to web root). For my new setup, I'm considering installing everything on my local machine. I'm afraid that it will slow down workstation performance (LAMP + Eclipse), and that compatibility problems will kick-in. What would you recommend? Should I develop using two separate machines? On one? Do you have experience using one of above configurations in your work?

  • IDirect3DDevice9::GetRenderTargetData() returns no data

    - by P. Avery
    I've got a simple function to get the rendertarget data of an RT( w/default pool ). This particular RT has a resolution of 1x1( it's the 10'th and final mip of a texture ). Here is my code to get data for IDirect3DSurface9 *pTargetSurface: IDirect3DSurface9 *pSOS = NULL; pd3dDevice->CreateOffScreenPlainSurface( 1, 1, D3DFMT_A8R8G8B8, D3DPOOL_SYSTEMMEM, &pSOS, NULL ); // get residual energy if( FAILED( hr = pd3dDevice->GetRenderTargetData( pTargetSurface, pSOS ) ) ) { DebugStringDX( ClassName, "Failed to IDirect3DDevice9::GetRenderTargetData() at DownsampleArea()", __LINE__, hr ); goto Exit; } // lock surface if( FAILED( hr = pSOS->LockRect( &rct, NULL, D3DLOCK_READONLY ) ) ) { DebugStringDX( ClassName, "Failed to IDirect3DSurface9::LockRect() at DownsampleArea()", __LINE__, hr ); goto Exit; } // get residual energy from downsampled texture pByte = ( BYTE* )rct.pBits; D3DXVECTOR4 vEnergy; vEnergy.z = ( float )pByte[ 0 ] / 255.0f; vEnergy.y = ( float )pByte[ 1 ] / 255.0f; vEnergy.x = ( float )pByte[ 2 ] / 255.0f; vEnergy.w = ( float )pByte[ 3 ] / 255.0f; V( pSOS->UnlockRect() ); All formatting and settings are correct, directx in debug mode shows no errors... The problem is that the 4 bytes above are 0...I know this to be incorrect by using PIX to debug...PIX shows that RGB bytes are 0.078 and Alpah is 1. These values are not less than that which can be represented by a single byte( 1 / 255 ). Any ideas? Am I copying rendertarget data correctly?

  • One of my VMs went boom using Virtual Box and how it got fixed

    - by Enrique Lima
    I am running an HP Envy 15, 16GB and 500GB (7200 RPM) Hard drive. Had a VM configured from another environment, created the virtual machine config file on Virtual Box, everything seemed ok. Fired it up, and it was  s   l   o   w, it took close to 10 minutes for it to load, and about 5 more to see Windows was in the process of loading before the BSOD.  Thought, maybe, just maybe it will not happen again … oh was I wrong. Frustration had already hit an all time high with this configuration and the number of issues I’ve had. How I did the troubleshooting … The best thing to do (IMO) is to step back, and gather your tools to debug this situation. Tools:  Virtual Box command line tools, Windows Debug. Virtual Box comes with a pretty good set of tools to examine, migrate and overall tasks to deal with VMs. The firs step:  use VBoxManage to prevent the VM from rebooting after the error to get enough time to really dig into the BSOD issue. Command used:   VBoxManage setextradata VMNAME "VBoxInternal/PDM/HaltOnReset" 1 Once this was done, the error reported was an “Inaccessible boot device” coming from a “Stop – 7B” type of error on the BSOD. The issue I had with this, my VM was configured to use a virtual SATA controller, and thought Windows 2008 R2 would handle this fine … again wrong!  Because the integration tools from the other product where wanting to take effect that was throwing everything off. The fix The fix was almost handed to me, edited the configuration for the VM, removed the SATA controller from it, added the virtual hard drive under an IDE controller, boot up and voilà … it works! I was then able to install the Virtual Box guest tools and such, but have decided to favor “keep on working” over “let’s try SATA again”

  • About output of vga_switcher

    - by zhangjie
    When IGD and DIS both exist in my pc,and I want to disable DIS,so I create a service to switch on and off the DIS.It works.Finally,I decide to add the service command into /etc/rc.local so that DIS will be powered off automatically.Unfortunately,it fails.There's only one command added by myself in the file /etc/rc.local,so I can affirm failure is caused by that added command. Before,I directly added the command "echo OFF /sys/kernel/debug..." into /etc/rc.local,and when I restarted,the system startup fails.So I thought maybe when the command is executed,the DIS hasn't been powered on or ready for work.So conflict occurs!It's just my prediction.Then I added one line command "sleep 1s" before the "echo OFF ...",it works nearly everytime when I start or restart pc,while fails sometimes. The output result of "cat /sys/kernel/debug..." is as following: 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :Pwr:0000:01:00.0 I want know 0000:00:02.0 means what?Time of first power on? If it was really time,I can set the command "sleep 2s" to wait for DIS powered on then "echo OFF ..." Thanks for your advice!

  • How to convert ISampleGrabber::BufferCB's buffer to a bitmap

    - by user2509919
    I am trying to use the ISampleGrabberCB::BufferCB to convert the current frame to bitmap using the following code: int ISampleGrabberCB.BufferCB(double sampleTime, IntPtr buffer, int bufferLength) { try { Form1 form1 = new Form1("", "", ""); if (pictureReady == null) { Debug.Assert(bufferLength == Math.Abs(pitch) * videoHeight, "Wrong Buffer Length"); } Debug.Assert(imageBuffer != IntPtr.Zero, "Remove Buffer"); Bitmap bitmapOfCurrentFrame = new Bitmap(width, height, capturePitch, PixelFormat.Format24bppRgb, buffer); MessageBox.Show("Works"); form1.changepicturebox3(bitmapOfCurrentFrame); pictureReady.Set(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } return 0; } However this does not seem to be working. Additionally it seems to call this function when i press a button which runs the following code: public IntPtr getFrame() { int hr; try { pictureReady.Reset(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } imageBuffer = Marshal.AllocCoTaskMem(Math.Abs(pitch) * videoHeight); try { gotFrame = true; if (videoControl != null) { hr = videoControl.SetMode(stillPin, VideoControlFlags.Trigger); DsError.ThrowExceptionForHR(hr); } if (!pictureReady.WaitOne(9000, false)) { throw new Exception("Timeout waiting to get picture"); } } catch { Marshal.FreeCoTaskMem(imageBuffer); imageBuffer = IntPtr.Zero; } return imageBuffer; } Once this code is ran I get a message box which shows 'Works' thus meaning my BufferCB must of been called however does not update my picture box with the current image. Is the BufferCB not called after every new frame? If so why do I not recieve the 'Works' message box? Finally is it possible to convert every new frame into a bitmap (this is used for later processing) using BufferCB and if so how? Edited code: int ISampleGrabberCB.BufferCB(double sampleTime, IntPtr buffer, int bufferLength) { Debug.Assert(bufferLength == Math.Abs(pitch) * videoHeight, "Wrong Buffer Length"); Debug.Assert(imageBuffer != IntPtr.Zero, "Remove Buffer"); CopyMemory(imageBuffer, buffer, bufferLength); Decode(buffer); return 0; } public Image Decode(IntPtr imageData) { var bitmap = new Bitmap(width, height, pitch, PixelFormat.Format24bppRgb, imageBuffer); bitmap.RotateFlip(RotateFlipType.RotateNoneFlipY); Form1 form1 = new Form1("", "", ""); form1.changepicturebox3(bitmap); bitmap.Save("C:\\Users\\...\\Desktop\\A2 Project\\barcode.jpg"); return bitmap; } Button code: public void getFrameFromWebcam() { if (iPtr != IntPtr.Zero) { Marshal.FreeCoTaskMem(iPtr); iPtr = IntPtr.Zero; } //Get Image iPtr = sampleGrabberCallBack.getFrame(); Bitmap bitmapOfFrame = new Bitmap(sampleGrabberCallBack.width, sampleGrabberCallBack.height, sampleGrabberCallBack.capturePitch, PixelFormat.Format24bppRgb, iPtr); bitmapOfFrame.RotateFlip(RotateFlipType.RotateNoneFlipY); barcodeReader(bitmapOfFrame); } public IntPtr getFrame() { int hr; try { pictureReady.Reset(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } imageBuffer = Marshal.AllocCoTaskMem(Math.Abs(pitch) * videoHeight); try { gotFrame = true; if (videoControl != null) { hr = videoControl.SetMode(stillPin, VideoControlFlags.Trigger); DsError.ThrowExceptionForHR(hr); } if (!pictureReady.WaitOne(9000, false)) { throw new Exception("Timeout waiting to get picture"); } } catch { Marshal.FreeCoTaskMem(imageBuffer); imageBuffer = IntPtr.Zero; } return imageBuffer; } I also still need to press the button to run the BufferCB Thanks for reading.

  • use svcutil to map multiple namespaces for generating wcf service proxies

    - by Pratik
    I want to use svcutil to map multiple wsdl namespace to clr namespace when generating service proxies. I use strong versioning of namespaces and hence the generated clr namespaces are awkward and may mean many client side code changes if the wsdl/xsd namespace version changes. A code example would be better to show what I want. // Service code namespace TestService.StoreService { [DataContract(Namespace = "http://mydomain.com/xsd/Model/Store/2009/07/01")] public class Address { [DataMember(IsRequired = true, Order = 0)] public string street { get; set; } } [ServiceContract(Namespace = "http://mydomain.com/wsdl/StoreService-v1.0")] public interface IStoreService { [OperationContract] List<Customer> GetAllCustomersForStore(int storeId); [OperationContract] Address GetStoreAddress(int storeId); } public class StoreService : IStoreService { public List<Customer> GetAllCustomersForStore(int storeId) { throw new NotImplementedException(); } public Address GetStoreAddress(int storeId) { throw new NotImplementedException(); } } } namespace TestService.CustomerService { [DataContract(Namespace = "http://mydomain.com/xsd/Model/Customer/2009/07/01")] public class Address { [DataMember(IsRequired = true, Order = 0)] public string city { get; set; } } [ServiceContract(Namespace = "http://mydomain.com/wsdl/CustomerService-v1.0")] public interface ICustomerService { [OperationContract] Customer GetCustomer(int customerId); [OperationContract] Address GetStoreAddress(int customerId); } public class CustomerService : ICustomerService { public Customer GetCustomer(int customerId) { throw new NotImplementedException(); } public Address GetStoreAddress(int customerId) { throw new NotImplementedException(); } } } namespace TestService.Shared { [DataContract(Namespace = "http://mydomain.com/xsd/Model/Shared/2009/07/01")] public class Customer { [DataMember(IsRequired = true, Order = 0)] public int CustomerId { get; set; } [DataMember(IsRequired = true, Order = 1)] public string FirstName { get; set; } } } 1. svcutil - without namespace mapping svcutil.exe /t:metadata TestSvcUtil\bin\debug\TestService.CustomerService.dll TestSvcUtil\bin\debug\TestService.StoreService.dll svcutil.exe /t:code *.wsdl *.xsd /o:TestClient\WebServiceProxy.cs The generated proxy looks like namespace mydomain.com.xsd.Model.Shared._2009._07._011 { public partial class Customer{} } namespace mydomain.com.xsd.Model.Customer._2009._07._011 { public partial class Address{} } namespace mydomain.com.xsd.Model.Store._2009._07._011 { public partial class Address{} } The client classes are out of any namespaces. Any change to xsd namespace would imply changing all using statements in my client code all build will break. 2. svcutil - with wildcard namespace mapping svcutil.exe /t:metadata TestSvcUtil\bin\debug\TestService.CustomerService.dll TestSvcUtil\bin\debug\TestService.StoreService.dll svcutil.exe /t:code *.wsdl *.xsd /n:*,MyDomain.ServiceProxy /o:TestClient\WebServicesProxy2.cs The generated proxy looks like namespace MyDomain.ServiceProxy { public partial class Customer{} public partial class Address{} public partial class Address1{} public partial class CustomerServiceClient{} public partial class StoreServiceClient{} } Notice that svcutil has automatically changed one of the Address class to Address1. I don't like this. All client classes are also inside the same namespace. What I want Something like this: svcutil.exe /t:code *.wsdl *.xsd /n:"http://mydomain.com/xsd/Model/Shared/2009/07/01, MyDomain.Model.Shared;http://mydomain.com/xsd/Model/Customer/2009/07/01, MyDomain.Model.Customer;http://mydomain.com/wsdl/CustomerService-v1.0, MyDomain.CustomerServiceProxy;http://mydomain.com/xsd/Model/Store/2009/07/01, MyDomain.Model.Store;http://mydomain.com/wsdl/StoreService-v1.0, MyDomain.StoreServiceProxy" /o:TestClient\WebServiceProxy3.cs This way I can logically group the clr namespace and any change to wsdl/xsd namespace is handled in the proxy generation only without affecting the rest of the client side code. Now this is not possible. The svcutil allows to map only one or all namespaces, not a list of mappings. I can do one mapping as shown below but not multiple svcutil.exe /t:code *.wsdl *.xsd /n:"http://mydomain.com/xsd/Model/Store/2009/07/01, MyDomain.Model.Address" /o:TestClient\WebServiceProxy4.cs But is there any solution. Svcutil is not magic, it is written in .Net and programatically generating the proxies. Has anyone written an alternate to svcutil or point me to directions so that I can write one.

  • W3WP crashes when initializing a collection

    - by asbjornu
    I've created an ASP.NET MVC application that has an initializer attached to the PreApplicationStartMethodAttribute. When initializing, a collection is instantiated that implements an interface I've defined. When I instantiate this collection, w3wp.exe crashes with the following two incomprehensible entries in the event log: Faulting application name: w3wp.exe, version: 7.5.7600.16385, time stamp: 0x4a5bd0eb Faulting module name: clr.dll, version: 4.0.30319.1, time stamp: 0x4ba21eeb Exception code: 0xc00000fd Fault offset: 0x0000000000001177 Faulting process id: 0x1348 Faulting application start time: 0x01cb0224882f4723 Faulting application path: c:\windows\system32\inetsrv\w3wp.exe Faulting module path: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clr.dll Report Id: c6a0941e-6e17-11df-864d-000acd16dcdb And: Fault bucket , type 0 Event Name: APPCRASH Response: Not available Cab Id: 0 Problem signature: P1: w3wp.exe P2: 7.5.7600.16385 P3: 4a5bd0eb P4: clr.dll P5: 4.0.30319.1 P6: 4ba21eeb P7: c00000fd P8: 0000000000001177 P9: P10: Attached files: These files may be available here: Analysis symbol: Rechecking for solution: 0 Report Id: c6a0941e-6e17-11df-864d-000acd16dcdb Report Status: 0 If I remove the instantiation of the collection, the application starts normally. If I leave the instantiation, w3wp crashes. If I modify the interface, w3wp still crashes. I've tried every variation I could come up with on the theme of keeping the instantiation but doing everything else differently, but w3wp still crashes. My biggest issue here is that I have absolutely no idea why w3wp is crashing. It's not a StackOverflowException or anything concrete like that, all I get is the unintelligent junk cited above. I've tried to use DebugDiag and IISState to debug the w3wp process, but DebugDiag is only available for post-dump analysis in x64 (I'm running on Windows 7 x64, so the w3wp process is thus 64 bit) and IISStat says the following when I try to run it: D:\Programs\iisstate>IISState.exe -p 9204 -d Symbol search path is: SRV*D:\Programs\iisstate\symbols*http://msdl.microsoft.com/download/symbols IISState is limited to processes associated with IIS. If you require a generic debugger, please use WinDBG or CDB. They are available for download from http://www.microsoft.com/ddk/debugging. This error may also occur if a debugger is already attached to the process being checked. Incorrect Process Attachment I've double-checked 10 times that the process ID of my w3wp process is correct. I'm suspecting that IISState too only can debug x86 processes. Setting a breakpoint anywhere in the application does absolutely nothing. The break point isn't hit and w3wp crashes as soon as the request comes through to IIS from the browser. Starting the application with F5 in Visual Studio 2010 or starting another application to get the w3wp process up and running and then attaching the VS2010 debugger to it and then visiting the faulting application doesn't help. I've also tried to add an HTTP module as described in KB-911816 as well as add this to my web.config file: <configuration> <runtime> <legacyUnhandledExceptionPolicy enabled="true" /> </runtime> </configuration> Needless to say, it makes absolutely no difference. So I'm left with no way to debug the w3wp process, no way to extract any information from it and complete garbage dumped in my event log. If anybody has any idea on how to debug this problem, please let me know! Update My collection was initialized based on RouteTable.Routes which might have thrown an exception (perhaps by not being initialized itself yet in such an early stage of the ASP.NET lifecycle). Postponing the communication with RouteTable.Routes until a later stage solved the problem. While I don't really need an answer to this question anymore, I still find it so obscure that I'll leave it for anyone to comment on and answer, because I found no existing posts on this problem anywhere, so it might be of good reference in the future.

  • Running 32 bit assembly code on a 64 bit Linux & 64 bit Processor : Explain the anomaly.

    - by claws
    Hello, I'm in an interesting problem.I forgot I'm using 64bit machine & OS and wrote a 32 bit assembly code. I don't know how to write 64 bit code. This is the x86 32-bit assembly code for Gnu Assembler (AT&T syntax) on Linux. //hello.S #include <asm/unistd.h> #include <syscall.h> #define STDOUT 1 .data hellostr: .ascii "hello wolrd\n"; helloend: .text .globl _start _start: movl $(SYS_write) , %eax //ssize_t write(int fd, const void *buf, size_t count); movl $(STDOUT) , %ebx movl $hellostr , %ecx movl $(helloend-hellostr) , %edx int $0x80 movl $(SYS_exit), %eax //void _exit(int status); xorl %ebx, %ebx int $0x80 ret Now, This code should run fine on a 32bit processor & 32 bit OS right? As we know 64 bit processors are backward compatible with 32 bit processors. So, that also wouldn't be a problem. The problem arises because of differences in system calls & call mechanism in 64-bit OS & 32-bit OS. I don't know why but they changed the system call numbers between 32-bit linux & 64-bit linux. asm/unistd_32.h defines: #define __NR_write 4 #define __NR_exit 1 asm/unistd_64.h defines: #define __NR_write 1 #define __NR_exit 60 Anyway using Macros instead of direct numbers is paid off. Its ensuring correct system call numbers. when I assemble & link & run the program. $cpp hello.S hello.s //pre-processor $as hello.s -o hello.o //assemble $ld hello.o // linker : converting relocatable to executable Its not printing helloworld. In gdb its showing: Program exited with code 01. I don't know how to debug in gdb. using tutorial I tried to debug it and execute instruction by instruction checking registers at each step. its always showing me "program exited with 01". It would be great if some on could show me how to debug this. (gdb) break _start Note: breakpoint -10 also set at pc 0x4000b0. Breakpoint 8 at 0x4000b0 (gdb) start Function "main" not defined.

What exactly is happening? I want to know the reason why exactly its exiting with exitstatus=1? Can some one please show me how to debug this program using gdb? Why did they change the system call numbers? Kindly change this program appropriately so that it can run correctly on this machine. EDIT: After reading Paul R's answer.

What exactly is happening in this case? Can someone please answer my questions and provide an x86-64 version of this code?

  • XSD Schema for XML with multiple structures

    - by Xetius
    I am attempting to write an XML Schema to cover a number of XML conditions which I may encounter. I have the same root element (serviceRequest) with different child elements. I was trying to use the xs:extension element to define multiple versions, but it is complaining about unexpected element orderInclusionCriteria etc. Am I going about this the right way, or is there a better way to define this? The other way I thought about this was to have a single xs:choice with all the options inside it, but this seemed somewhat inelegant. These XSD files are for use within XMLBeans if that makes any difference. I have Given the following 2 examples of XML: 1) <?xml version="1.0" encoding="utf-8"?> <serviceRequest method="GOO" debug="NO"> <sessionId sID="ABC1234567" /> <orderInclusionCriteria accountId="1234567" accountNum="1234567890" /> </serviceRequest> 2) <?xml version="1.0" encoding="utf-8"?> <serviceRequest method="GOO" debug="NO"> <sessionId sID="ABC1234567" /> <action aType='MakePayment'> <makePayment accountID='CH91015165S' amount='5.00' /> </action> </serviceRequest> I thought I could use the following schema file: <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="serviceRequest" type="ServiceRequestType" /> <xs:element name="session" type="SessionType" /> <xs:attribute name="method" type="xs:string" /> <xs:attribute name="debug" type="xs:string" /> <xs:complexType name="SessionType"> <xs:attribute name="sID" use="required"> <xs:simpleType> <xs:restriction base="xs:string"/> </xs:simpleType> </xs:attribute> </xs:complexType> <xs:complexType name="ServiceRequestType"> <xs:sequence> <xs:element ref="session" /> </xs:sequence> <xs:attribute ref="method" /> <xs:attribute ref="debug" /> </xs:complexType> <xs:complexType name="OrderTrackingServiceRequest"> <xs:complexContent> <xs:extension base="ServiceRequestType"> <xs:complexType> <xs:sequence> <xs:element name="OrderInclusionCriteria" type="xs:string" /> </xs:sequence> </xs:complexType> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="Action"> <xs:complexContent> <xs:extension base="ServiceRequestType"> <xs:complexType> <xs:sequence> <xs:element name="makePayment"> <xs:complexType> <xs:attribute name="accountID" type="xs:string" /> <xs:attribute name="amount" type="xs:string" /> <xs:complexType> </xs:element> </xs:sequence> <xs:attribute name="aType" type="xs:string" /> </xs:complexType> </xs:extension> </xs:complexContent> </xs:complexType> </xs:schema>

  • NHibernate Mapping and Querying Where Tables are Related But No Foreign Key Constraint

    - by IanT8
    I'm fairly new to NHibernate, and I need to ask a couple of questions relating to a very frequent scenario. The following simplified example illustrates the problem. I have two tables named Equipment and Users. Users is a set of system administrators. Equipment is a set of machinery. Tables: Users table has UserId int and LoginName nvarchar(64). Equipment table has EquipId int, EquipType nvarchar(64), UpdatedBy int. Behavior: System administrators can make changes to Equipment, and when they do, the UpdatedBy field of Equipment is "normally" set to their User Id. Users can be deleted at any time. New Equipment items have an UpdatedBy value of null. There's no foreign key constraint on Equipment.UpdatedBy which means: Equipment.UpdatedBy can be null. Equipment.UpdatedBy value can be = existing User.UserId value Equipment.UpdatedBy value can be = non-existent User.UserId value To find Equipment and who last updated the Equipment, I might query like this: select E.EquipId, E.EquipName, U.UserId, U.LoginName from Equipment E left outer join Users U on. E.UpdatedBy = U.UserId Simple enough. So how to do that in NHibernate? My mappings might be as follows: <?xml version="1.0" encoding="utf-8"?> <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="Data" assembly="Data"> <class name="User" table="Users"> <id name="Id" column="UserId" unsaved-value="0"> <generator class="native" /> </id> <property name="LoginName" unique="true" not-null="true" /> </class> <class name="Equipment" table="Equipment"> <id name="Id" column="EquipId" type="int" unsaved-value="0"> <generator class="native" /> </id> <property name="EquipType" /> <many-to-one name="UpdatedBy" class="User" column="UpdatedBy" /> </class> </hibernate-mapping> So how do I get all items of equipment and who updated them? using (ISession session = sessionManager.OpenSession()) { List<Data.Equipment> equipList = session .CreateCriteria<Data.Equipment>() // Do I need to SetFetchmode or specify that I // want to join onto User here? If so how? .List<Data.Equipment>(); foreach (Data.Equipment item in equipList) { Debug.WriteLine("\nEquip Id: " + item.Id); Debug.WriteLine("Equip Type: " + item.EquipType); if (item.UpdatedBy.Country != null) Debug.WriteLine("Updated By: " + item.UpdatedBy.LoginName); else Debug.WriteLine("Updated by: Nobody"); } } When Equipment.UpdatedBy = 3 and there is no Users.UserId = 3, the above fail I also have a feeling that the generated SQL is a select all from Equipment followed by many select columns from Users where UserId = n whereas I'd expected NHibernate to left join as per my plain ordinary SQL and do one hit. If I can tell NHibernate to do the query in one hit, how do I do that? Time is of the essence on my project, so any help you could provide is gratefully received. If you're speculating about how NHibernate might work in this scenario, please say you're not absolutely sure. Many thanks.

  • Is it a missing implementation with JPA implementation of hibernate??

    - by Jegan
    Hi all, On my way in understanding the transaction-type attribute of persistence.xml, i came across an issue / discrepency between hibernate-core and JPA-hibernate which looks weird. I am not pretty sure whether it is a missing implementation with JPA of hibernate. Let me post the comparison between the outcome of JPA implementation and the hibernate implementation of the same concept. Environment Eclipse 3.5.1 JSE v1.6.0_05 Hibernate v3.2.3 [for hibernate core] Hibernate-EntityManger v3.4.0 [for JPA] MySQL DB v5.0 Issue 1.Hibernate core package com.expt.hibernate.core; import java.io.Serializable; public final class Student implements Serializable { private int studId; private String studName; private String studEmailId; public Student(final String studName, final String studEmailId) { this.studName = studName; this.studEmailId = studEmailId; } public int getStudId() { return this.studId; } public String getStudName() { return this.studName; } public String getStudEmailId() { return this.studEmailId; } private void setStudId(int studId) { this.studId = studId; } private void setStudName(String studName) { this.studName = stuName; } private void setStudEmailId(int studEmailId) { this.studEmailId = studEmailId; } } 2.

Then the issue comes when you run the driver program.
