  • Elmah and 404s under IIS6

    - by tomfanning
    Just wondering if it's possible to get Elmah to log 404s that aren't picked up by the ASP.NET framework - i.e. the 404s that IIS spots and replies to. Presumably this would involve some kind of entry in IIS - web site properties - Custom Errors tab. Can't find any reference on how to do this.

Check InnerException for exception details. at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary() at SalesSimplicityPO_SL.POSvc.GetPurchaseOrdersCompletedEventArgs.get_Result() at SalesSimplicityPO_SL.About.mySvc_GetPurchaseOrdersCompleted(Object sender, GetPurchaseOrdersCompletedEventArgs e) at SalesSimplicityPO_SL.POSvc.POSvcClient.OnGetPurchaseOrdersCompleted(Object state) What is the problem does anyone know? I load and call my web service like.. BasicHttpBinding binding = new BasicHttpBinding(); EndpointAddress address = new EndpointAddress(new Uri("http://localhost/POSystem/POSvc.svc")); POSvc.POSvcClient mySvc = new POSvc.POSvcClient(binding, address); mySvc.InsertPOCompleted += new EventHandler<SalesSimplicityPO_SL.POSvc.InsertPOCompletedEventArgs>(mySvc_InsertPOCompleted); mySvc.InsertPOAsync(InitialsTextBox.Text.ToString(), DescTextBox.Text.ToString(), ClientTextBox.Text.ToString()); Works great in debug....

  • Is there a better way to avoid an infinite loop using winforms?

    - by Hamish Grubijan
    I am using .Net 3.5 for now. Right now I am using a using trick to disable and enable events around certain sections of code. The user can change either days, hours, minutes or total minutes, and that should not cause an infinite cascade of events (e.g. minutes changing total, total changing minutes, etc.) While the code does what I want, there might be a better / more straight-forward way. Do you know of any? For brawny points: This control will be used by multiple teams - I do not want to make it embarrassing. I suspect that I do not need to reinvent the wheel when defining hours in a day, days in week, etc. Some other standard .Net library out there must have it. Any other remarks regarding code? This using (EventHacker.DisableEvents(this)) business - that must be a common pattern in .Net ... changing the setting temporarily. What is the name of it? I'd like to be able to refer to it in a comment and also read up more on current implementations. In the general case not only a handle to the thing being changed needs to be remembered, but also the previous state (in this case previous state does not matter - events are turned on and off unconditionally). Then there is also a possibility of multi-threaded hacking. One could also utilize generics to make the code arguably cleaner. Figuring all this out can lead to a multi-page blog post. I'd be happy to hear some of the answers. P.S. Does it seem like I suffer from obsessive compulsive disorder? Some people like to get things finished and move on; I like to keep them open ... there is always a better way. // Corresponding Designer class is omitted. using System; using System.Windows.Forms; namespace XYZ // Real name masked { interface IEventHackable { void EnableEvents(); void DisableEvents(); } public partial class PollingIntervalGroupBox : GroupBox, IEventHackable { private const int DAYS_IN_WEEK = 7; private const int MINUTES_IN_HOUR = 60; private const int HOURS_IN_DAY = 24; private const int MINUTES_IN_DAY = MINUTES_IN_HOUR * HOURS_IN_DAY; private const int MAX_TOTAL_DAYS = 100; private static readonly decimal MIN_TOTAL_NUM_MINUTES = 1; // Anything faster than once per minute can bog down our servers. private static readonly decimal MAX_TOTAL_NUM_MINUTES = (MAX_TOTAL_DAYS * MINUTES_IN_DAY) - 1; // 99 days should be plenty. // The value above was chosen so to not cause an overflow exception. // Watch out for it - numericUpDownControls each have a MaximumValue setting. public PollingIntervalGroupBox() { InitializeComponent(); InitializeComponentCustom(); } private void InitializeComponentCustom() { this.m_upDownDays.Maximum = MAX_TOTAL_DAYS - 1; this.m_upDownHours.Maximum = HOURS_IN_DAY - 1; this.m_upDownMinutes.Maximum = MINUTES_IN_HOUR - 1; this.m_upDownTotalMinutes.Maximum = MAX_TOTAL_NUM_MINUTES; this.m_upDownTotalMinutes.Minimum = MIN_TOTAL_NUM_MINUTES; } private void m_upDownTotalMinutes_ValueChanged(object sender, EventArgs e) { setTotalMinutes(this.m_upDownTotalMinutes.Value); } private void m_upDownDays_ValueChanged(object sender, EventArgs e) { updateTotalMinutes(); } private void m_upDownHours_ValueChanged(object sender, EventArgs e) { updateTotalMinutes(); } private void m_upDownMinutes_ValueChanged(object sender, EventArgs e) { updateTotalMinutes(); } private void updateTotalMinutes() { this.setTotalMinutes( MINUTES_IN_DAY * m_upDownDays.Value + MINUTES_IN_HOUR * m_upDownHours.Value + m_upDownMinutes.Value); } public decimal TotalMinutes { get { return m_upDownTotalMinutes.Value; } set { m_upDownTotalMinutes.Value = value; } } public decimal TotalHours { set { setTotalMinutes(value * MINUTES_IN_HOUR); } } public decimal TotalDays { set { setTotalMinutes(value * MINUTES_IN_DAY); } } public decimal TotalWeeks { set { setTotalMinutes(value * DAYS_IN_WEEK * MINUTES_IN_DAY); } } private void setTotalMinutes(decimal nTotalMinutes) { if (nTotalMinutes < MIN_TOTAL_NUM_MINUTES) { setTotalMinutes(MIN_TOTAL_NUM_MINUTES); return; // Must be carefull with recursion. } if (nTotalMinutes > MAX_TOTAL_NUM_MINUTES) { setTotalMinutes(MAX_TOTAL_NUM_MINUTES); return; // Must be carefull with recursion. } using (EventHacker.DisableEvents(this)) { // First set the total minutes this.m_upDownTotalMinutes.Value = nTotalMinutes; // Then set the rest this.m_upDownDays.Value = (int)(nTotalMinutes / MINUTES_IN_DAY); nTotalMinutes = nTotalMinutes % MINUTES_IN_DAY; // variable reuse. this.m_upDownHours.Value = (int)(nTotalMinutes / MINUTES_IN_HOUR); nTotalMinutes = nTotalMinutes % MINUTES_IN_HOUR; this.m_upDownMinutes.Value = nTotalMinutes; } } // Event magic public void EnableEvents() { this.m_upDownTotalMinutes.ValueChanged += this.m_upDownTotalMinutes_ValueChanged; this.m_upDownDays.ValueChanged += this.m_upDownDays_ValueChanged; this.m_upDownHours.ValueChanged += this.m_upDownHours_ValueChanged; this.m_upDownMinutes.ValueChanged += this.m_upDownMinutes_ValueChanged; } public void DisableEvents() { this.m_upDownTotalMinutes.ValueChanged -= this.m_upDownTotalMinutes_ValueChanged; this.m_upDownDays.ValueChanged -= this.m_upDownDays_ValueChanged; this.m_upDownHours.ValueChanged -= this.m_upDownHours_ValueChanged; this.m_upDownMinutes.ValueChanged -= this.m_upDownMinutes_ValueChanged; } // We give as little info as possible to the 'hacker'. private sealed class EventHacker : IDisposable { IEventHackable _hackableHandle; public static IDisposable DisableEvents(IEventHackable hackableHandle) { return new EventHacker(hackableHandle); } public EventHacker(IEventHackable hackableHandle) { this._hackableHandle = hackableHandle; this._hackableHandle.DisableEvents(); } public void Dispose() { this._hackableHandle.EnableEvents(); } } } }

  • How can you tell the source of the data when using the Stream.BeginRead Method?

    - by xarzu
    When using the Stream.BeginRead Method, and you are reading from a stream into a memory, how is it determined where you are reading the data from? See: http://msdn.microsoft.com/en-us/library/system.io.stream.beginread.aspx In the list of parameters, I do not see one that tells where the data is being read from: Parameters buffer Type: System.Byte[] The buffer to read the data into. offset Type: System.Int32 The byte offset in buffer at which to begin writing data read from the stream. count Type: System.Int32 The maximum number of bytes to read. callback Type: System.AsyncCallback An optional asynchronous callback, to be called when the read is complete. state Type: System.Object A user-provided object that distinguishes this particular asynchronous read request from other requests.

  • How do I do automatic data serialization of data objects in Haskell

    - by Adam Gent
    One of the huge benefits in languages that have some sort of reflection/introspecition is that objects can be automatically constructed from a variety of sources. For example in Java I can use the same objects for persisting to a db (with Hibernate) serializing to XML (with JAXB) or serializing to JSON (json-lib). You can do the same in Ruby and Python also usually following some simple rules for properties or annotations for Java. Thus I don't need lots "Domain Transfer Objects". I can concentrate on the domain I am working in. It seems in very strict FP like Haskell and Ocaml this is not possible. Particularly Haskell. The only thing I have seen is doing some sort of preprocessing or meta-programming (ocaml). Is it just accepted that you have to do all the transformations from the bottom upwards? In other words you have to do lot of boring work to turn a data type in haskell into JSON/XML/DB Row object and back again into a data object.

  • ProviderException: InvalidCastException

    - by JS
    Few of our clients are regularly getting invalid cast exception, with variations i.e. InvalidCastException / ProviderException, but both generating from method call: System.Web.Security.SqlRoleProvider.GetRolesForUser(String username) The other variation is: Exception type: InvalidCastException Exception message: Unable to cast object of type System.Int32 to type System.String. I had a look at application event log which shows: Stack trace: at System.Web.Security.SqlRoleProvider.GetRolesForUser(String username) at System.Web.Security.RolePrincipal.IsInRole(String role) at System.Web.Configuration.AuthorizationRule.IsTheUserInAnyRole(StringCollection roles, IPrincipal principal) at System.Web.Configuration.AuthorizationRule.IsUserAllowed(IPrincipal user, String verb) at System.Web.Configuration.AuthorizationRuleCollection.IsUserAllowed(IPrincipal user, String verb) at System.Web.Security.UrlAuthorizationModule.OnEnter(Object source, EventArgs eventArgs) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)* Has anyone come across this issue, and if so what is the fix? Thanks JS

  • Localized tables and Entity Framework

    - by Pyttroll
    Hi all, I have a scenario where I need to localized values of objects in my database. Let's say you have an application that can create animals, if the user is english the value of the "Name" property of an animal would be entered as "Cat" in the UI whereas it would be entered as "Chat" in french. The animal culture table would contain 2 records pointing to the same animal in the parent table. When reading values back, if the value of "Name" does not exist in the user culture the default value (value the object was originally created with) would be used. The following diagrams demonstrate how the data is stored in SQL: I'm trying to map this schema to an object model using the Entity Framework, I'm a bit confused as to what the best way to approach the problem. Is EF appropriate for this? Should I used EF4? This EF model will be used by .NET RIA Services. Thanks, Pierre-Yves Troel Ayuda Media Systems http://www.ayudasystems.com

  • How does git-diff generate hunk descriptions?

How does git generate these descriptions? How can I tweak them to show the method name that the patch applies to?

  • C# failing LDAP queries

    - by jpkomick
    I'm trying to access an LDAP directory via the SearchRequest object in C#. I can make the same calls via an LDAP library running in and iPhone app, as well as directly via a terminal session. However, the C# queries all seem to fail. var search = new SearchRequest("ou=calendar,dc=ualberta,dc=ca", "term=*,course=094398,class=*", System.DirectoryServices.Protocols.SearchScope.Subtree, attributeLst); This returns a list of terms for the course calendar. However, making the following calls won't return results for specific courses var search = new SearchRequest("ou=calendar,dc=ualberta,dc=ca", "term=1330,course=094398", System.DirectoryServices.Protocols.SearchScope.Subtree, attributeLst); The attributeLst object has proper attribute names included, but the query always returns with zero results. Any suggestions anyone has would be greatly appreciated. Thanks.

  • NHibernate cascade and inverse

    - by Kordonme
    I have three mappings as follows: public MainChapterMap() { // other properties HasMany(x => x.ClientSpecific).KeyColumn("MainChapterId"); } public MainChapterClientMap() { // other properties References(x => x.MainChapter).Column("MainChapterId"); HasMany(x => x.Details).KeyColumn("MainChapterClientId"); } public MainChapterClientDetailMap() { // other properties References(x => x.MainChapterClient).Column("MainChapterClientId"); } MainChapter has many client-specific chapters. The client-specific chapters (MainChapterClient) has many translations (MainChapterClientDetail) The dele rules should be as follow: When deleting a MainChapter Delete the MainChapterClient row Delete the MainChapterClientDetail row(s) When deleting a MainChapterClient Do NOT delete the MainChapter row Delete the MainChapterClientDetail row(s) When deleting a MainChapterClientDetail Do NOT delete the MainChapter row Do NOT delete the MainChapterClientDetail row(s) But I no matter what I end up getting this error: deleted object would be re-saved by cascade (remove deleted object from associations)[Entities.MainChapterClient#39] I'm not sure how to set up my cascades anymore. Any help are more than welcomed!

  • how to get the size of a C global array into an assembly program written for the avr architecture co

    - by johannes
    I have a .c file with the following uint8_t buffer[32] I have a .S file where I want to do the following cpi r29, buffer+sizeof(buffer) The second argument for cpi muste be an imidiate value not a location. But unfortunetly sizeof() is a c operator. Both files, are getting compiled to seperate object files and linked afterwards. If I do avr-objdump -x file.c. Amongst other things, I get the size of the buffer. So it is already available in the object file. How do I access the size of the buffer in my assembly file at compile time?

  • Do I need to Dispose to deregister events?

    - by Sean
    Say I have two classes, and neither of them are GUI components. Class A is a short lived object that registers for an event declared by a long lived object B. For example public A(B b) { b.ChangeEvent += OnChangeEvent; } If A never deregisters from B's event, will A never be garbage collected? Does A need a Dispose method just to deregister from B's event? There is also a related second question. If A and B should both live for the entire execution time of the application, does A need to deregister?

  • Custom Validator and specifying type of message

    - by user102533
    I have a custom validation in the enterprise validation block. The DoValidate method is as shown below. protected override void DoValidate(Double objectToValidate, object currentTarget, string key, ValidationResults validationResults) { if (!IsSalMoreThanMinWage(objectToValidate)) { //Here I need to mark this message as a "Warning" LogValidationResult(validationResults, "Salary is too low for this state", currentTarget, key); } } I'd need to mark this validation failure as a "warning" message. In the front end, when I iterate through the ValidationResults collection and grab a ValidationResult object, I would need to identify and group different types of messages and render them differently. My question is - how do I mark a failure as a warning?

  • When should I use static methods in a class and what are the benefits?

    - by NAVEED
    I have concept of static variables but what are the benefits of static methods in a class. I have worked on some projects but I did not make a method static. Whenever I need to call a method of a class, I create an object of that class and call the desired method. Static variable in a method holds it's value even when method is executed but accessible only in its containing method but what is the best definition of static method? Is calling the static method without creating object of that class is the only benefit of static method? What is the accessible range for static method? What is the syntax to create and calling static method in php? Thanks

  • How to create tests for poco objects

    - by Simon G
    Hi, I'm new to mocking/testing and wanting to know what level should you go to when testing. For example in my code I have the following object: public class RuleViolation { public string ErrorMessage { get; private set; } public string PropertyName { get; private set; } public RuleViolation( string errorMessage ) { ErrorMessage = errorMessage; } public RuleViolation( string errorMessage, string propertyName ) { ErrorMessage = errorMessage; PropertyName = propertyName; } } This is a relatively simple object. So my question is: Does it need a unit test? If it does what do I test and how? Thanks

  • getting around circular references in Delphi

    Is there a way of getting around circular unit references in Delphi? Maybe a newer version of delphi or some magic hack or something? My delphi project has 100 000+ lines of code mostly based on singleton classes. I need to refactor this, but that would mean several months of "circular reference" hell :)
