• How can I update an expression in a Runt::Schedule object?

  - by Reid Beels

  Runt provides a Schedule class for managing collections of events, each represented by a temporal expression. The Schedule class provides an update method, cited in the release notes as "allowing clients to update existing expressions". The implementation of this method, however, simply calls a supplied block, providing the temporal expression for the specified event (as shown). # From lib/runt/schedule.rb:61 # # Call the supplied block/Proc with the currently configured # TemporalExpression associated with the supplied Event. # def update(event,&block) block.call(@elems[event]) end How is one expected to use this method to update an expression?

• Alternative to COM blind aggregation in .NET for class with private interface

  - by Philip

  When extending a COM class in unmanaged C++ where the original class has private interfaces, one way to do this is through the concept of blind aggregation. The idea is that any interface not explicitly implemented on the outer aggregating class is 'blindly' forwarded to the inner aggregated class. Now .NET as far as I can figure out does not support COM aggregation natively. A somewhat tedious workaround is to create a .NET class where you implement all the required COM interfaces directly on the .NET class and simply forward to an instance of the actual COM class for any methods you don't want to override. The problem I have is when the original COM object has one or more private interfaces, i.e. undocumented interfaces that are nonetheless used by some consumers of the original class. Using blind aggregation in unmanaged C++ this is a non-issue as the calls to the private interfaces are automatically forwarded to the original class, however I can't find any way of doing the same thing in .NET. Are there any other ways of accomplishing this with .NET?

• What is the equivalent to Java's canvas object in C#?

  - by Winston

  I'm working on creating a basic application that will let a user draw (using a series of points) and I plan to do something with these points. If this were Java, I think I would probably use a canvas object and some Java2D calls to draw what I want. All the tutorials I've read on C#/Drawing involve writing your own paint method and adding it to the paint event for the form. However, I'm interested in having some traditional Form controls as well and I don't want to be drawing over them. So, is there a "Canvas" object where I can constrain what I'm drawing on? Also, is WinForms a poor choice given this use case? Would WPF have more features that would help enable me to do what I want? Or Silverlight?

• How can I interrupt a ServerSocket accept() method?

  - by lukeo05

  Hi, In my main thread I have a while(listening) loop which calls accept() on my ServerSocket object, then starts a new client thread and adds it to a Collection when a new client is accepted. I also have an Admin thread which I want to use to issue commands, like 'exit', which will cause all the client threads to be shut down, shut itself down, and shut down the main thread, by turning listening to false. However, the accept() call in the while(listening) loop blocks, and there doesn't seem to be any way to interrupt it, so the while condition cannot be checked again and the program cannot exit! Is there a better way to do this? Or some way to interrupt the blocking method? Thanks!

• How does a VxWorks scheduler get executed?

  - by Ashwin

  Hello All, Would like to know how the scheduler gets called so that it can switch tasks. As in even if its preemptive scheduling or round robin scheduling - the scheduler should come in to picture to do any kind of task switching. Supposing a low priority task has an infinite loop - when does the scheduler intervene and switch to a higher priority task? Query is: 1. Who calls the scheduler? [in VxWorks] 2. If it gets called at regular intervals - how is that mechanism implemented? Thanks in advance. --Ashwin

• Loading Youtube Iframe API with RequireJS

  - by davidgnin

  I'm trying to use the Youtube Iframe API inside a module definded with Require JS. As this API is loaded async and calls a function once is loaded, I used a requireJS plugin called "async", that worked before with google maps api. However, this time something isn't working. My module starts this way: define(['text!fmwk/widgets/video/video.html','fmwk/utils/browser','async!http://www.youtube.com/iframe_api'], function (videoTpl,root) { ... }); and chrome console fires this error: Uncaught Error: Load timeout for modules: async!http://www.youtube.com/iframe_api_unnormalized3,async!http://www.youtube.com/iframe_api http://requirejs.org/docs/errors.html#timeout If I don't use async plugin the object YT or its functions are undefinded, and the same happens if I download the API code. The API is loaded sometimes if I put an script tag in the head tag of the html file. All this is expected, but I don't understand because async plugin fails. Thank you for your attention and help :)

• select random value from each type

  - by Joseph Mastey

  I have two tables, rating: +-----------+-----------+-------------+----------+ | rating_id | entity_id | rating_code | position | +-----------+-----------+-------------+----------+ | 1 | 1 | Quality | 0 | | 2 | 1 | Value | 0 | | 3 | 1 | Price | 0 | +-----------+-----------+-------------+----------+ And rating_option +-----------+-----------+------+-------+----------+ | option_id | rating_id | code | value | position | +-----------+-----------+------+-------+----------+ | 1 | 1 | 1 | 1 | 1 | | 2 | 1 | 2 | 2 | 2 | | 3 | 1 | 3 | 3 | 3 | | 4 | 1 | 4 | 4 | 4 | | 5 | 1 | 5 | 5 | 5 | | 6 | 2 | 1 | 1 | 1 | | 7 | 2 | 2 | 2 | 2 | | 8 | 2 | 3 | 3 | 3 | | 9 | 2 | 4 | 4 | 4 | | 10 | 2 | 5 | 5 | 5 | | 11 | 3 | 1 | 1 | 1 | | 12 | 3 | 2 | 2 | 2 | | 13 | 3 | 3 | 3 | 3 | | 14 | 3 | 4 | 4 | 4 | | 15 | 3 | 5 | 5 | 5 | +-----------+-----------+------+-------+----------+ I need a SQL query (not application level, must stay in the database) which will select a set of ratings randomly. A sample result would look like this, but would pick a random value for each rating_id on subsequent calls: +-----------+-----------+------+-------+----------+ | option_id | rating_id | code | value | position | +-----------+-----------+------+-------+----------+ | 1 | 1 | 1 | 1 | 1 | | 8 | 2 | 3 | 3 | 3 | | 15 | 3 | 5 | 5 | 5 | +-----------+-----------+------+-------+----------+ I'm totally stuck on the random part, and grouping by rating_id has been a crap shoot so far. Any MySQL ninjas want to take a stab? Thanks, Joe

• Why doesn't javascript function aliasing work?

  - by codeninja

  I have some Firebug console function calls that I wanted to disable when Firebug wasn't enabled, e.g. console isn't defined. This works fine in IE6 and FF3, but not in Chrome: var log; if(console){ log = console.log; }else{ log = function(){ return; } } I get an "Uncaught TypeError: Illegal Invocation" in Chrome =/ I read about the issue here, where you have to apply a context, which is kind of new to me... and I can't seem to figure how to accomplish the above in all browsers...

• Remove another user's lock obtained with sp_getapplock on SQL Server

  - by joshperry

  We have a system that uses sp_getapplock to create an exclusive mutex any time someone opens an order in the GUI. This is used to prevent multiple people from making changes to an order simultaneously. Sometimes people will open an order and go home, leaving it open. This effectively blocks anyone from being able to make changes to the order. I then get emails, calls and end up doing a kill <spid> in enterprise manager. Obviously I've gotten sick of this and want to make a quick self-service webform. The main problem I've run into is that kill requires sysadmin privileges, which I do not want to give to the user that the our website runs as. I have tried sp_releaseapplock but this doesn't let you release another user's lock (even when calling it as a sysadmin). So, finally my question; does anyone know of an alternative method to release a lock that was obtained by another user using sp_getapplock?

• WaitForSingleObject( )

  - by Rakesh Agarwal

  I have got myself stuck into a really amazing issue here.The code is like as below. class A { public: A(){ m_event = CreateEvent(NULL, false, false, NULL); // create an event with initial value as non-signalled m_thread = _beginthread(StaticThreadEntry, 0, this); // create a thread } static void StaticThreadEntry(A * obj) { obj->ThreadEntry(); } void ThreadEntry(); }; void A::ThreadEntry() { WaitforSingleObject(m_event,INFINITE); } int main() { A a; SetEvent(m_event); // sets the event to signalled state which causes the running thread to terminate WaitForSingleObject(m_thread, INFINITE); // waits for the thread to terminate return 0; } Problem : When the above code is run,sometimes( 1 out of 5 ) it hangs and the control gets stuck in the call to WaitforSingleObject()( inside the main function ).The code always calls SetEvent() function to ensure that the thread would terminate before calling Wait() function. I do not see any reason why it should ever hang?

• Win32 call order

  - by DD

  Hi all, I have two windows that I send scripted input to. The procedure goes as this BringWindowToTop( window1 ); i = Build input structures( window1 ); SendInput(i); BringWindowToTop( window2 ); i = Build input structures( window2 ); SendInput(i); I was having trouble with inputs not being sent and the correct time. I put delays after each call and saw that input from the first SendInput() was processed after window2 is brought to top. Same thing at the end of the loop as well. Are SendInput calls buffered? If so, how can I make sure of a serial execution of this code? Thanks

• How to create a VS2010 extension that uses Language Services

  - by Hades32

  Creating extensions got much easier with Vs2010, but this seems not to be the case for everything... My aim: I wnat to make method calls and property uses of STATIC classes ITALIC. (Just like Eclipse and Java) I think I need to talk to the C# Language Service for this information, but searching for "Language Service" just yields results on how to CREATE one, not how to use one of the existing ones... To get this question a little more general: How do I get information about properties of the code (static/visibility etc) for using it in a VSX?

• Customising event delegates in the jQuery validation plug-in

  - by Russell

  I am currently setting up the jQuery validation plug-in for use in our project. By default, there are some events automatically set up for handling. I.e. focus in/out, key up events on all inputs fire validation. I want it to only fire when the submit button is clicked. This functionality seems to be in-built into the plug-in, which is making it difficult to do this (without modifying the plug-in code, Not What I Want To Do). I have found the eventDelegate function calls in the plugin code prototype method: $(this.currentForm) .validateDelegate(":text, :password, :file, select, textarea", "focusin focusout keyup", delegate) .validateDelegate(":radio, :checkbox, select, option", "click", delegate); When I remove these lines from the plug-in I get my result, however I would much rather do something Outside the plug-in to achieve this. Can anybody please help me? If you need any more details, please let me know. I have searched google with little success. Thanks

• Compiled Queries and "Parameters cannot be sequences"

  - by David B

  I thought that compiled queries would perform the same query translation as DataContext. Yet I'm getting a run-time error when I try to use a query with a .Contains method call. Where have I gone wrong? //private member which holds a compiled query. Func<DataAccess.DataClasses1DataContext, List<int>, List<DataAccess.TestRecord>> compiledFiftyRecordQuery = System.Data.Linq.CompiledQuery.Compile <DataAccess.DataClasses1DataContext, List<int>, List<DataAccess.TestRecord>> ((dc, ids) => dc.TestRecords.Where(tr => ids.Contains(tr.ID)).ToList()); //this method calls the compiled query. public void FiftyRecordCompiledQueryByID() { List<int> IDs = GetRandomInts(50); //System.NotSupportedException //{"Parameters cannot be sequences."} List<DataAccess.TestRecord> results = compiledFiftyRecordQuery (myContext, IDs); }

• Validate form fields from InfoPath custom code

  - by Alex Angas

  I'm developing an InfoPath form for Forms Services. It has these views: View 1 asks the user to input some basic initial data View 2 calls a web service based on data in View 1 and populates drop-downs accordingly At the bottom of View 1 I've added a Next > button to move to View 2. As part of clicking that button I would like the inputs in View 1 to be validated first. However, there don't appear to be any rules that validate a view or anything in the object model to execute validation rules. Is there code that can trigger a field's validation event?

• Calling a method with an instance of derived class of derived generic type

  - by madsbirk

  Okay, so I have classes class B<T> : A<T> class L : K and a method void Method(A<K> a) {...} What I would like to do is this b = new B<L>(); Method(b); //error But it is not possible to b to the correct type. Indeed it is not possible to make this cast A<K> t = new A<L>(); //error I would really like to not have to change the internals of Method. I have no problems making changes to B and/or L. Do I have any options for making some sort of workaround? I guess it should be possible for Method to execute all of its method calls etc. on b, since B derives from A and L derives from K?

• Have you been in cases where TDD increased development time?

  - by BillyONeal

  Hello everyone :) I was reading http://stackoverflow.com/questions/2512504/tdd-how-to-start-really-thinking-tdd and I noticed many of the answers indicate that tests + application should take less time than just writing the application. In my experience, this is not true. My problem though is that some 90% of the code I write has a TON of operating system calls. The time spent to actually mock these up takes much longer than just writing the code in the first place. Sometimes 4 or 5 times as long to write the test as to write the actual code. I'm curious if there are other developers in this kind of a scenario.

• C# app fails to load Matlab DLL when running from a shared drive?

  - by jg

  I have a C# .NET 2.0 program that calls a Matlab .dll file that I created using Matlab Builder for .NET. This Matlab .dll file is a wrapper for a m file function that I need to call from my C# program. Everything works fine when I run this app from my local drive. However once I copy the app to a shared drive the Matlab dll fails when it's first loaded. I setup caspol to allow .NET programs to run from shared drives. Does anyone know what could cause this problem or a tool that I could use to easily figure out what the problem is? Thanks.

• T4MVC calling controller methods multiple times?

  - by Maslow

  I suspected there was some hidden magic somewhere that stopped what looks like actual method calls all over the place in T4MVC. Then I had a view fail to compile, and the stackTrace went into my actual method, not the generated code in T4MVC. <%=Ajax.ActionLink("Apply", "Apply", new RouteValueDictionary() { { "shortName", item.Shortname } }, new AjaxOptions() { UpdateTargetId = "masterstatus" })%> <%=Html.ActionLink("Apply",MVC.Alliance.Apply(item.Shortname),new AjaxOptions() { UpdateTargetId = "masterstatus" }) %> The second method threw an exception on compile because the method Apply in my controller has an [Authorize] attribute so that if someone that isn't logged on clicks this, they get redirected to login, then right back to this page. There they can click on apply again, this time being logged in. And yes I realize one is Ajax.ActionLink while the other is Html.ActionLink I did try them both with the T4MVC version. Is this a fluke or is it actually calling into the real methods and running my database calling code just to generate the views?

• Jquery - intercept links created by ajax request

  - by Kaskade

  Hi, I have some jquery code that intercepts links clicked on a page : $(document).ready(function() { $("a").click(function() { //do something here }); }); My problem is there are certain parts of the page that have not finished loading on document ready. They are populated via ajax calls. The links in these sections are not intercepted by my jQuery function above. I need the function to be run on document ready initially but then I need the new links to also have the same logic applied to them. Any help would be very much appreciated. This is an area that I am very unfamiliar with. I have written the jQuery stuff but the ajax code is an external component that I have no control over. Thanks in advance

• Modify url for bookmarking using JavaScript

  - by jamesaharvey

  I'm exploring my options for modifying urls in the browser bar for bookmarking purposes. Ideally, I'd like to add querystring parameters and cannot determine if this is even possible. I don't want the page to refresh and want to add querystring values on link clicks, ajax calls, etc. If I can't add querystring parameters, then I'd like to add hash values (http:://someurl.com#hash-value). How should I go about doing this? Should I use plain JavaScript or a framework (jquery, prototype, etc.) and/or framework plugin.

• Using UIImageView for a flipbook anim on iphone

  - by Joey

  I'm using UIImageView to run a flipbook anim like this: mIntroAnimFrame = [[UIImageView alloc] initWithFrame:CGRectMake( 0, 0, 480, 320); mIntroAnimFrame.image = [UIImage imageNamed:@"frame0000.tif"]; Basically, when determine it is time, I flip the image by just calling: mIntroAnimFrame.image = [UIImage imageNamed:@"frame0000.tif"]; again with the right frame. Should I be doing this differently? Are repeated calls to set the image this way possibly bogging down main memory, or does each call essentially free the previous UIImage because nothing else references it? I suspect the latter is true. Also, is there an easy way to preload the images? The anim seems to slow down at times. Should I simply load all the images into a dummy UIImage array so they are preloaded, then refer to it when I want to show it with mIntroAnimFrame.image = mPreloadedArray[i]; ?

• DWR and Jquery into spring MVC 2.5

  - by Mark Estrada

  Hi, From my shallow reading, Spring MVC does not support jquery directly. It does enable integration with DWR framework. From my understanding of DWR, it is an ajax framework that allows you to call javas methods from javascript. Can I use both in my application? With Jquery handling most of the javascript code and client side interaction and DWR making the ajax calls? I am leaning towards learning jquery but there is no out of the box support for it in spring 2.5.

• How should I use random.jumpahead in Python

  - by Peter Smit

  I have a application that does a certain experiment 1000 times (multi-threaded, so that multiple experiments are done at the same time). Every experiment needs appr. 50.000 random.random() calls. What is the best approach to get this really random. I could copy a random object to every experiment and do than a jumpahead of 50.000 * expid. The documentation suggests that jumpahead(1) already scrambles the state, but is that really true? Or is there another way to do this in 'the best way'? (No, the random numbers are not used for security, but for a metropolis hasting algorithm. The only requirement is that the experiments are independent, not whether the random sequence is somehow predictable or so)

• Android : How to use flurry API

  - by SWDeveloper

  Hi All, I am using flurry in my app, and I am new to that. I have some doubts. My requirement is, In my main activity I will start a session, and calling onevent method in some activities. And I am not calling endSeesion method anywhere. I want to know when the FlurryAgent will hit the flurry site. So do I need to call endSession then where should I call that method? How FlurryAgent maintains the session. In case if I call like this FlurryAgent.onEndSession(this); FlurryAgent.onStartSession(this, Constants.FLURRY_API); FlurryAgent.setLogEnabled(true); will it work like this - previous session will be closed and new session will be started. I can track only http urls using fiddler, when I try to track https calls then its getting crashed, I have modified ssl settings in fiddler, I dont know how to configure my emulator. Thanks in Advance.
