• Any way to separate unit tests from integration tests in VS2008?

  - by AngryHacker

  I have a project full of tests, unit and integration alike. Integration tests require that a pretty large database be present, so it's difficult to make it a part of the build process simply because of the time that it takes to re-initialize the database. Is there a way to somehow separate unit tests from integration tests and have the build server just run the unit tests? I see that there is an Ordered Unit test in VS2008, which allows you to pick and choose tests, but I can't make it just execute alone, without all the others. Is there a trick that I am missing? Or perhaps I could adorn the unit tests with an attribute? What are some of the approaches people are using? P.S. I know I could use mocking for integration tests (just to make them go faster) but then it wouldn't be a true integration test.

• implementing feature structures: what data type to use?

  - by Dervin Thunk

  Hello. In simplistic terms, a feature structure is an unordered list of attribute-value pairs. [number:sg, person:3 | _ ], which can be embedded: [cat:np, agr:[number:sg, person:3 | _ ] | _ ], can subindex stuff and share the value [number:[1], person:3 | _ ], where [1] is another feature structure (that is, it allows reentrancy). My question is: what data structure would people think this should be implemented with for later access to values, to perform unification between 2 fts, to "type" them, etc. There is a full book on this, but it's in lisp, which simplifies list handling. So, my choices are: a hash of lists, a list of lists, or a trie. What do people think about this?

• CRM plugin to execute when opportunity is reopened

  - by splatto

  I need to write a plugin for Dynamics CRM 4.0 that executes when a closed opportunity is reopened in order to change the salesstagecode. My questions are: When I register a new step to the plugin, what attribute(s) should I filter on? What property on the entity should I check the value of? and What should I look for the value of this entity to be so I can determine if the plugin execution should continue? I've typically written asynchronous workflows and my experience writing plugins is still developing, so I'd appreciate any help and clarification that can be offered. Please see below the plugin skeleton I've written public void Execute(IPluginExecutionContext context) { if (context.InputParameters.Properties.Contains("Target") && context.InputParameters.Properties["Target"] is DynamicEntity) { ICrmService service = context.CreateCrmService(false); DynamicEntity entity = (DynamicEntity)context.InputParameters.Properties["Target"]; if (entity.Name == EntityName.opportunity.ToString()) { if (entity.Properties.Contains(/*What Property Should I Check Here?*/)) { //And what value should I be looking for in that property? } } } }

• How do I override ToString in C# enums?

  - by scraimer

  In the post Enum ToString, a method is described to use the custom attribute DescriptionAttribute like this: Enum HowNice { [Description("Really Nice")] ReallyNice, [Description("Kinda Nice")] SortOfNice, [Description("Not Nice At All")] NotNice } And then, you call a function GetDescription, using syntax like: GetDescription<HowNice>(NotNice); // Returns "Not Nice At All" But that doesn't really help me when I want to simply populate a ComboBox with the values of an enum, since I cannot force the ComboBox to call GetDescription. What I want has the following requirements: Reading (HowNice)myComboBox.selectedItem will return the selected value as the enum value. The user should see the user-friendly display strings, and not just the name of the enumeration values. So instead of seeing "NotNice", the user would see "Not Nice At All". Hopefully, the solution will require minimal code changes to existing enumerations. Obviously, I could implement a new class for each enum that I create, and override its ToString(), but that's a lot of work for each enum, and I'd rather avoid that. Any ideas? Heck, I'll even throw in a hug as a bounty :-)

I have set up my Postsharp attribute as so [Serializable] public class NLogTraceAttribute : OnMethodBoundaryAspect { private readonly string _logLevel; ILogger logger; public NLogTraceAttribute(string logLevel) { _logLevel = logLevel; logger = new Logger("TraceAttribute"); } public override void OnEntry(MethodExecutionArgs args) { LogAction("Enter", args); } public override void OnExit(MethodExecutionArgs args) { LogAction("Leave", args); } private void LogAction(string action, MethodExecutionArgs args) { var argumentsInfo = args.GetArgumentsInfo(); logger.Log(_logLevel, "{0}: {1}.{2}{3}", action, args.Method.DeclaringType.Name, args.Method.Name, argumentsInfo); } } and trying to use it as [NLogTrace(NLogLevel.Debug)] However when compiling the project I am getting the following error: Error 26 Cannot serialize the aspects: Type 'NLog.Logger' in Assembly 'NLog, Version=2.0.0.0, Culture=neutral, PublicKeyToken=5120e14c03d0593c' is not marked as serializable..

• Cast/initialize submodels of a Backbone Model

  - by nambrot

  I think I have a pretty simple problem that is just pretty difficult to word and therefore hard to find a solution for. Setup: PathCollection is a Backbone.Collection of Paths Path is a Backbone.Model which contains NodeCollection (which is a Backbone.Collection) and EdgeCollection (which is a Backbone.Collection). When I fetch PathCollection paths = new PathCollection() paths.fetch() obviously, Paths get instantiated. However, I'm missing the spot where I can allow a Path to instantiate its submodels from the attribute hashes. I can't really use parse, right? Basically im looking for the entry point for a model when its instantiated and set with attributes. I feel like there must be some convention for it.

• GCC destructor behaviour

  - by joveha

  I've noticed a difference in behaviour for gcc's destructor when compiled under linux and crosscompiled with mingw. On linux the destructor will not get called unless the program terminates normally by itself (returns from main). I guess that kind of makes sense if you take signal handlers into account. On Win32 however, the destructor is called if the program is terminated by say a CTRL-C, but not when killed from the Task Manager. Why is this? And what would you suggest to make the destructor get called no matter how the process terminates - on Win32 in particular? Example code: #include <stdio.h> int main(int argc, char **argv) { printf("main\n"); while(1) {} return 0; } __attribute__((destructor)) static void mydestructor(void) { printf("destructor\n"); }

• Parsing boolean from configuration section in web.config

  - by Bloopy

  I have a custom configuration section in my web.config. One of my classes is grabbing from this: <myConfigSection LabelVisible="" TitleVisible="true"/> I have things working for parsing if I have true or false, however if the attribute is blank I am getting errors. When the config section tries to map the class to the configuration section I get an error of "not a valid value for bool" on the 'LabelVisible' part. How can I parse "" as false in my myConfigSection class? I have tried this: [ConfigurationProperty("labelsVisible", DefaultValue = true, IsRequired = false)] public bool? LabelsVisible { get { return (bool?)this["labelsVisible"]; } But when I try and use what is returned like so: graph.Label.Visible = myConfigSection.LabelsVisible; I get an error of: 'Cannot implicitly convert type 'bool?' to 'bool'. An explicit conversion exists (are you missing a cast?) Thanks for any suggestions!

• jquery button click not firing asp.net button

  - by lloydphillips

  I've got a .net button that has an href attribute value set to 'javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ctl00$cp1$ucInvoiceSearch$btnSearch", "", true, "", "", false, true))'. I've got a textbox that when I press enter I want it to fire this event. Doing the 'Enter' event isn't an issue but I can't get the event on the href to fire using .click(). Here's my function so far: $("[id*='tbInvNo']").keyup(function(event){ var $btn = $(".pnl-invoice-search"); if(event.keyCode == 13) $btn.click(); }); I've got no idea how to get this to fire. Hope someone can help - jQuery and asp.net are driving me up the wall today! :(

• django search and filter in Google App Engine

  - by alexarsh

  Hi, I'm trying to add filter and search to my site. It's exactly the same code as in another working django project. The difference is that this time I do it with app engine. my views: http://slexy.org/view/s21GMw2sh1 I have 2 problems: 1.) I get error: "'Query' object has no attribute 'all'" on line 59 in views. As I understand it's something to do with the fact that GAE queryset is different from django queryset. How can I fix that? 2.) If I have 'search' in my request.GET I also fall on line 54 in my views. This is because I can't search by Q object in GAE, I guess. How can I fix that? Thanks, Alex A.

• REXML Formatting issues

  - by dagda1

  Hi, I am using REXML to edit an xml file but have ran into difficulties with formatting. My original code looked like this: file = File.new( destination) doc = REXML::Document.new file doc.elements.each("configuration/continuity2") do |element| element.attributes["islive"] = "true" element.attributes["pagetitle"] = "#{@client.page_title}" element.attributes["clientname"] = "#{@client.name}" end doc.elements.each("configuration/continuity2/plans") do |element| element.attributes["storebasedir"] = "#{@client.store_dir}" end I first of all had to add the following code as REXML was adding single quotes instead of double quotes. I found the following via google: REXML::Attribute.class_eval( %q^ def to_string %Q[#@expanded_name="#{to_s().gsub(/"/, '&quot;')}"] end ^ ) I also have a problem in that REXML is reformatting the document. are there ways to stop this?

• Setting current culture with threads in ASP.NET MVC

  - by mare

  Here's an example of SetCulture attribute which inside does something like this: public void OnActionExecuting(ActionExecutingContext filterContext) { string cultureCode = SetCurrentLanguage(filterContext); if (string.IsNullOrEmpty(cultureCode)) return; HttpContext.Current.Response.Cookies.Add( new HttpCookie("Culture", cultureCode) { HttpOnly = true, Expires = DateTime.Now.AddYears(100) } ); filterContext.HttpContext.Session["Culture"] = cultureCode; CultureInfo culture = new CultureInfo(cultureCode); System.Threading.Thread.CurrentThread.CurrentCulture = culture; System.Threading.Thread.CurrentThread.CurrentUICulture = culture; } I was wondering how does this affect a site with multiple users logged on and each one setting their own culture? What is the scope of a thread here with regards to the IIS worker process (w3wp) that the site is running in?

• Ant 1.8 include or import with nested resource collection

  - by Danny

  I'd like to have Ant automatically include or import resources matching a particular pattern, but I'm really struggling with the syntax. Here's what I've tried: <import> <fileset dir="${basedir}" includes="*-graph.xml" /> </import> However, I just get the error message import requires file attribute or at least one nested resource The documentation for import (and include) both say that you can use a nested resource collection, and the documentation for resource collections says <fileset> is a resource collection. I've Googled and can't find any useful examples at all. I'm using Ant 1.8.1 (verified with ant -version)

• How do I customize what a third party MSM does?

  - by sqlrob

  I'm trying to convert a project in Visual Studio 2008 from static linking of the CRT to dynamic linking. This was easy enough, and I added the CRT MSM and policy MSM to my Wix file with no problems. I am not that happy with the MSI that is output though, it is much larger than what I expected. Looking at the MSI with Orca shows three copies of the CRT DLLs that I need. From looking at the conditions, one of the sets is used for pre-XP installs. Since the system requirements are XP and later, how do I remove this component without touching the original MSM? This needs to be done in an automated build, so Orca isn't a possible solution. Plus, when I tried it with Orca, the filesize remained the same after deleting the File and Component rows. And somewhat related, how do I set the permanent attribute in the components that remain?

• jQuery Validation 1.10 and MVC server-side errors

  - by sam360

  This feature used to work just fine on my website. If I added a custom error to ModelState, the input on the page would be marked as "input-validation-error" and the Html.ValidationMessage() would take care of rendering a span with the error message inside it. Due to incompatibility reasons we had to upgrade our jQuery Validation to 1.10: Now when I add a custom error to ModelState, I can debug and see that the HTML elements being rendered correctly, but as soon as the page load is completed, jQuery Validation removes the error message and set the "class" attribute of the input to "valid"! Has any one else come across this issue? UPDATE Testing further shows that the error message is shown on the screen until the field gains focus. As soon as the field gains focus jQuery Validation removes the customer server-side error message and marks the field as good.

• Retrieve Button value with jQuery

  - by Simon Hutton

  A simple one, I'm trying to retrieve the value attribute of a button when its been pressed using jQuery, here's what I have: <script type="text/javascript"> $(document).ready(function() { $('.my_button').click(function() { alert($(this).val()); }); }); </script> <button class="my_button" name="buttonName" value="buttonValue"> Button Label</button> In Firefox my alert displays 'buttonValue' which is great but in IE7 it displays 'Button Label'. What jQuery should I use to always get the button's value? Or should I be using a different approach? Many thanks. ANSWER: I'm now using <input class="my_button" type="image" src="whatever.png" value="buttonValue" />

• 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.

• Define Servlet Context in WAR-File

  - by er4z0r

  Hi, How can I tell e.g. Tomcat to use a specific context path when given my WAR-File? Example: I have a war file created by maven build and the resulting name of the file is rather long. So I do not want the tomcat manager application to use the filename of the war as the context. Supplying a context.xml in META-INF did not produce the desired results I also found this in the documentation for the path attribute of Context: The value of this field must not be set except when statically defining a Context in server.xml, as it will be inferred from the filenames used for either the .xml context file or the docBase. So it does not seem to be the right way to tell the application-server what the path for my WAR should be. Any more hints?

• Html5 Audio plays only once in my Javascript code.

  - by Poul

  I have a dashboard web-app that I want to play an alert sound if its having problems connecting. The site's ajax code will poll for data and throttle down its refresh rate if it can't connect. Once the server comes back up, the site will continue working. In the mean time I would like a sound to play each time it can't connect (so I know to check the server). Here is that code. This code works. var error_audio = new Audio("audio/"+settings.refresh.error_audio); error_audio.load(); //this gets called when there is a connection error. function onConnectionError() { error_audio.play(); } However the 2nd time through the function the audio doesn't play. Digging around in Chrome's debugger the 'played' attribute in the audio element gets set to true. Setting it to false has no results. Any ideas?

• Why does an onclick property set with setAttribute fail to work in IE?

  - by Aeon

  Ran into this problem today, posting in case someone else has the same issue. var execBtn = document.createElement('input'); execBtn.setAttribute("type", "button"); execBtn.setAttribute("id", "execBtn"); execBtn.setAttribute("value", "Execute"); execBtn.setAttribute("onclick", "runCommand();"); Turns out to get IE to run an onclick on a dynamically generated element, we can't use setAttribute. Instead, we need to set the onclick property on the object with an anonymous function wrapping the code we want to run. execBtn.onclick = function() { runCommand() }; BAD IDEAS: You can do execBtn.setAttribute("onclick", function() { runCommand() }); but it will break in IE in non-standards mode according to @scunliffe. You can't do this at all execBtn.setAttribute("onclick", runCommand() ); because it executes immediately, and sets the result of runCommand() to be the onClick attribute value, nor can you do execBtn.setAttribute("onclick", runCommand);

• Invoke an action that is using ASP.NET MVC [Authorize] from outside the application

  - by Nate Bross

  Is this possible? I'd like to expose a URL (action) such as http://mysever/myapp/UpdateHeartbeat/. In my MVC application it looks like [Authorize] [AcceptsVerbs(HttpVerbs.Post)] public ActionResult UpdateHeartbeat() { // update date in DB to DateTime.Now } Now, in my MVC application the user has logged in via FORMS authentication and they can execute that action to their hearts content. What I want to do, is hit that URL progromatically (as part of an API that I wouldl like to build) -- is there a way I can do that without removing the [Authorize] attribute and adding username/password as parameters to the POST?
