  • Box Shadow on only 3 sides

    - by Connor
    I have two overlapping divs that have css3 box shadows. The trouble is that even when I set the z-index I will still need to eliminate one of the div's box-shadow. I have seen cases where negative spreads and zero values are used but I don't think that would work here. The code I have now is: #bulb-top { position: relative; width: 280px; height: 280px; background-color: #E5F7A3; -webkit-border-radius: 280px; -moz-border-radius: 280px; border-radius: 280px; border: 8px solid #FFF40C; top: -430px; margin-left: auto; margin-right: auto; -webkit-box-shadow: 0px 0px 15px 1px #FFF40C; -moz-box-shadow: 0px 0px 15px 1px #FFF40C; box-shadow: 0px 0px 15px 1px #FFF40C; z-index: 4; } #bulb-bottom { position: relative; width: 140px; height: 120px; background-color: #E5F7A3; -moz-border-radius-topleft: 0px; -moz-border-radius-topright: 0px; -moz-border-radius-bottomright: 30px; -moz-border-radius-bottomleft: 30px; -webkit-border-radius: 0px 0px 30px 30px; border-radius: 0px 0px 30px 30px; border-left: 8px solid #FFF40C; border-right: 8px solid #FFF40C; border-bottom: 8px solid #FFF40C; top: -455px; margin-left: auto; margin-right: auto; -webkit-box-shadow: 0px 0px 15px 1px #FFF40C; -moz-box-shadow: 0px 0px 15px 1px #FFF40C; box-shadow: 0px 0px 15px 1px #FFF40C; z-index: 5; } http://jsfiddle.net/minitech/g42vq/3/

  • Creating thumbnails PHP problem

    - by Wayne
    I have this source code where I got it from net tutsplus. I have configured it and made it work in one PHP file. It does work by transferring the original image, but it does not generate to the thumbnails folder. <?php $final_width_of_image = 100; $path_to_image_directory = "../../img/events/" . urldecode($_GET['name']) . "/"; $path_to_thumbs_directory = "../../img/events/" . urldecode($_GET['name']) . "/thumbnails/"; function createThumbnail($filename) { if(preg_match('/[.](jpg)$/', $filename)) { $im = imagecreatefromjpeg($path_to_image_directory . $filename); } elseif(preg_match('/[.](gif)$/', $filename)) { $im = imagecreatefromgif($path_to_image_directory . $filename); } elseif(preg_match('/[.](png)$/', $filename)) { $im = imagecreatefrompng($path_to_image_directory . $filename); } $ox = imagesx($im); $oy = imagesy($im); $nx = $final_width_of_image; $ny = floor($oy * ($final_width_of_image / $ox)); $nm = imagecreatetruecolor($nx, $ny); imagecopyresized($nm, $im, 0,0,0,0,$nx,$ny,$ox,$oy); imagejpeg($nm, $path_to_thumbs_directory . $filename); $tn = '<img src="' . $path_to_thumbs_directory . $filename . '" alt="image" />'; echo $tn; } if(isset($_FILES['fupload'])) { if(preg_match('/[.](jpg)|(gif)|(png)$/', $_FILES['fupload']['name'])) { $filename = $_FILES['fupload']['name']; $source = $_FILES['fupload']['tmp_name']; $target = $path_to_image_directory . $filename; move_uploaded_file($source, $target); createThumbnail($filename); } } ?> Basically it is supposed to generate a thumbnail of the uploaded image and store the original image into a different folder. The paths are correct, it works by getting the folder name in the URL, it does work, but nothing works for the thumbnails folder. BEFORE you ask this related question, yes, thumbnails generation does work on my server by the PHP GD, I have tested it separately. So this is not the problem. :) How do I get this to work? :(

  • Access violation when running native C++ application that uses a /clr built DLL

    - by doobop
    I'm reorganzing a legacy mixed (managed and unmanaged DLLs) application so that the main application segment is unmanaged MFC and that will call a C++ DLL compiled with /clr flag that will bridge the communication between the managed (C# DLLs) and unmanaged code. Unfortuantely, my changed have resulted in an Access violation that occurs before the application InitInstance() is called. This makes it very difficult to debug. The only information I get is the following stack trace. > 64006108() ntdll.dll!_ZwCreateMutant@16() + 0xc bytes kernel32.dll!_CreateMutexW@12() + 0x7a bytes So, here are some sceanrios I've tried. - Turned on Exceptions-Win32 Exceptions-c0000005 Access Violation to break when Thrown. Still the most detail I get is from the above stack trace. I've tried the application with F10, but it fails before any breakpoints are hit and fails with the above stack trace. - I've stubbed out the bridge DLL so that it only has one method that returns a bool and that method is coded to just return false (no C# code called). bool DllPassthrough::IsFailed() { return false; } If the stubbed out DLL is compiled with the /clr flag, the application fails. If it is compiled without the /clr flag, the application runs. - I've created a stub MFC application using the Visual Studio wizard for multidocument applications and call DllPassthrough::IsFailed(). This succeeds even with the /clr flag used to compile the DLL. - I've tried doing a manual LoadLibrary on winmm.lib as outlined in the following note Access violation when using c++/cli. The application still fails. So, my questions are how to solve the problem? Any hints, strategies, or previous incidents. And, failing that, how can I get more information on what code segment or library is causing the access exception? If I try more involved workarounds like doing LoadLibrary calls, I'd like to narrow it to the failing libraries. Thanks. BTW, we are using Visual Studio 2008 and the project is being built against the .NET 2.0 framework for the managed sections.

  • Anyone have experience calling Rake from MSBuild for code gen and other benefits? How did it go? Wha

    - by Charlie Flowers
    While programming in C# using Visual Studio 2008, I often wish for "automatic" code generation. If possible, I'd like to achieve it by making my MSBuild solution file call out to Rake, which would call Ruby code for the code generation, having the resulting generated files automatically appear in my solution. Here's one business example (of many possible examples I could name) where this kind of automatic code generation would be helpful. In a recent project I had an interface with some properties that contained dollar amounts. I wanted a second interface and a third interface that had the same properties as the first interface, except they were "qualified" with a business unit name. Something like this: public interface IQuarterlyResults { double TotalRevenue { get; set; } double NetProfit { get; set; } } public interface IConsumerQuarterlyResults { double ConsumerTotalRevenue { get; set; } double ConsumerNetProfit { get; set; } } public interface ICorporateQuarterResults { double CorporateTotalRevenue { get; set; } double CorporateNetProfit { get; set; } } In this example, there is a "Consumer Business Unit" and a "Corporate Business Unit". Every property on IQuarterlyResults becomes a property called "Corporate" + [property name] on ICorporateQuarterlyResults, and likewise for IConsumerQuarterlyResults. Why make interfaces for these, rather than merely having an instance of IQuarterlyResults for Consumer and another instance for Corporate? Because, when working with the calculator object I was building, the user had to deal with 100's of properties, and it is much less confusing if he can deal with "fully qualified" property names such as "ConsumerNetProfit". But let's not get bogged down in this example. It is only an example and not the main question. The main question is this: I love using Ruby and ERB for code generation, and I love using Rake to manage dependencies between tasks. To solve the problem above, what I'd like to do is have MSBuild call out to Rake, and have Rake / Ruby read the list of properties on the "core" interface and then generate the code to make all the dependent interfaces and their properties. This would get triggered every time I do a build, because I'd put it into the MSBuild file for the VS.NET solution. Has anyone tried anything like this? How did it work out for you? What insights can you share about pros, cons, tips for success, etc.? Thanks!

  • SpringMvc java.lang.NullPointerException When Posting Form To Server [closed]

    - by dev_darin
    I have a form with a user name field on it when i tab out of the field i use a RESTFUL Web Service that makes a call to a handler method in the controller. The method makes a call to a DAO class that checks the database if the user name exists. This works fine, however when the form is posted to the server i call the same exact function i would call in the handler method however i get a java.lang.NullPointerException when it accesses the class that makes a call to the DAO object. So it does not even access the DAO object the second time. I have exception handlers around the calls in all my classes that makes calls. Any ideas as to whats happening here why i would get the java.lang.NullPointerException the second time the function is called.Does this have anything to do with Spring instantiating DAO classes using a Singleton method or something to that effect? What can be done to resolve this? This is what happens the First Time The Method is called using the Web Service(this is suppose to happen): 13011 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - Inside jdbcOfficersDAO 13031 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL query 13034 [http-8084-2] DEBUG org.springframework.jdbc.core.JdbcTemplate - Executing prepared SQL statement [SELECT userName FROM crimetrack.tblofficers WHERE userName = ?] 13071 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Fetching JDBC Connection from DataSource 13496 [http-8084-2] DEBUG org.springframework.jdbc.core.StatementCreatorUtils - Setting SQL statement parameter value: column index 1, parameter value [adminz], value class [java.lang.String], SQL type unknown 13534 [http-8084-2] DEBUG org.springframework.jdbc.datasource.DataSourceUtils - Returning JDBC Connection to DataSource 13537 [http-8084-2] INFO com.crimetrack.jdbc.JdbcOfficersDAO - No username was found in exception 13537 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz does NOT exist The Second time When The Form Is 'Post' and a validation method handles the form and calls the same method the web service would call: 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - UserName is not null so going to check if its valid for :adminz 17199 [http-8084-2] INFO com.crimetrack.service.OfficerRegistrationValidation - User Name in try.....catch block is adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - Inside Do UserNameExist about to validate with username : adminz 17199 [http-8084-2] INFO com.crimetrack.service.ValidateUserNameManager - UserName :adminz EXCEPTION OCCURED java.lang.NullPointerException ValidateUserNameManager.java public class ValidateUserNameManager implements ValidateUserNameIFace { private OfficersDAO officerDao;

  • Web reference problem on WCF

    - by kaivalya
    I have a WCF service which I am able to connect to from my web application and get data. I now added a web reference to this wcf project to a wsdl file that a shipping company provides. Intention is to get shipping quotes.. I am able to access the objects that are generated from this wsdl file but when I call service.Authenticate("DEMO"); method almost nothing happens. I debug and see the debugger continue to the next lines but there is no change on service parameters and service.isauthorized is null.. Can you lead me to how I should debug this further and things I should check, or if there are additional steps that I need to ensure to have a web reference working on wcf app Thanks using System; using System.Collections.Generic; using System.Linq; using System.Runtime.Serialization; using System.ServiceModel; using System.Text; using ShippingCalculator.com.freight.api; namespace ShippingCalculator { public class ShippingService : IShippingService { freight_service service = new freight_service(); public string GetData(int value) { service.setConnectionType(".net"); service.Authenticate("DEMO"); OriginRequest origin = new OriginRequest(); origin.zip = "60101"; DestinationRequest destination = new DestinationRequest(); destination.zip = "10001"; PackageRequest package = new PackageRequest(); package.weight = "10"; ShipmentInfoRequest shipmentInfo = new ShipmentInfoRequest(); shipmentInfo.ship_date = DateTime.Now.AddDays(5); service.setOrigin(origin); service.setDestination(destination); service.setPackage(package); service.setShipmentInfo(shipmentInfo); Quote quote = service.getQuote(); return string.Format("Quote Number: {0}<br /> ", quote.QuoteNumber); } } } using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using ShippingTestApp.ShippingServiceReference; namespace ShippingTestApp.Controllers { [HandleError] public class HomeController : Controller { public ActionResult Index() { ShippingServiceClient shipClient = new ShippingServiceClient(); shipClient.GetData(0); ViewData["Message"] = shipClient.GetData(0); return View(); } } }

It looks something like this (the Timer class is from the System.Threading namespace): public partial class MyService : ServiceBase { private Timer _timer; private int _timeIntervalBetweenRuns = 10000; public MyService() { InitializeComponent(); } protected override void OnStart(string[] args) { // when NT Service starts - create timer to wake up every 10 seconds _timer = new Timer(OnTimer, null, _timeIntervalBetweenRuns, Timeout.Infinite); } protected override void OnStop() { // on stop - stop timer by freeing it _timer = null; } private void OnTimer(object state) { // when the timer fires, e.g. when 10 seconds are over // stop the timer from firing again by freeing it _timer = null; // check for mail and sent out notifications, if required - works just fine MailHandler handler = new MailHandler(); handler.CheckAndSendMail(); // once done, re-enable the timer by creating it from scratch _timer = new Timer(OnTimer, null, _timeIntervalBetweenRuns, _timeIntervalBetweenRuns); } } Sending the mail and all works just fine, and the service also wakes up every 10 seconds (in reality, this is a setting from a config file - simplified for this example). However, at times, the service seems to wake up too quickly.... 2010-04-09 22:50:16.390 2010-04-09 22:50:26.460 2010-04-09 22:50:36.483 2010-04-09 22:50:46.500 2010-04-09 22:50:46.537 ** why again after just 37 milliseconds...... ?? 2010-04-09 22:50:56.507 Works fine to 22:50:45.500 - why does it log another entry just 37 milliseconds later?? Here, it seems it's totally out of whack.... seems to wake up twice or even three times every time 10 seconds are over.... 2010-04-09 22:51:16.527 2010-04-09 22:51:26.537 2010-04-09 22:51:26.537 2010-04-09 22:51:36.543 2010-04-09 22:51:36.543 2010-04-09 22:51:46.553 2010-04-09 22:51:46.553 2010-04-09 22:51:56.577 2010-04-09 22:51:56.577 2010-04-09 22:52:06.590 2010-04-09 22:52:06.590 2010-04-09 22:52:06.600 2010-04-09 22:52:06.600 Any ideas why?? It's not a huge problem, but I'm concerned it might start to put too much load on the server, if the interval I configure (10 seconds, 30 seconds - whatever) seems to be ignored more and more, the longer the service runs. Have I missed something very fundamental in my service code?? Am I ending up with multiple timers, or something?? I can't seem to really figure it out..... have I picked the wrong timer (System.Threading.Timer) ? There's at least 3 Timer classes in .NET - why?? :-)

  • How to use Crtl in a Delphi unit in a C++Builder project? (or link to C++Builder C runtime library)

    - by Craig Peterson
    I have a Delphi unit that is statically linking a C .obj file using the {$L xxx} directive. The C file is compiled with C++Builder's command line compiler. To satisfy the C file's runtime library dependencies (_assert, memmove, etc), I'm including the crtl unit Allen Bauer mentioned here. unit FooWrapper; interface implementation uses Crtl; // Part of the Delphi RTL {$L FooLib.obj} // Compiled with "bcc32 -q -c foolib.c" procedure Foo; cdecl; external; end. If I compile that unit in a Delphi project (.dproj) everthing works correctly. If I compile that unit in a C++Builder project (.cbproj) it fails with the error: [ILINK32 Error] Fatal: Unable to open file 'CRTL.OBJ' And indeed, there isn't a crtl.obj file in the RAD Studio install folder. There is a .dcu, but no .pas. Trying to add crtdbg to the uses clause (the C header where _assert is defined) gives an error that it can't find crtdbg.dcu. If I remove the uses clause, it instead fails with errors that __assert and _memmove aren't found. So, in a Delphi unit in a C++Builder project, how can I export functions from the C runtime library so they're available for linking? I'm already aware of Rudy Velthuis's article. I'd like to avoid manually writing Delphi wrappers if possible, since I don't need them in Delphi, and C++Builder must already include the necessary functions. Edit For anyone who wants to play along at home, the code is available in Abbrevia's Subversion repository at https://tpabbrevia.svn.sourceforge.net/svnroot/tpabbrevia/trunk. I've taken David Heffernan's advice and added a "AbCrtl.pas" unit that mimics crtl.dcu when compiled in C++Builder. That got the PPMd support working, but the Lzma and WavPack libraries both fail with link errors: [ILINK32 Error] Error: Unresolved external '_beginthreadex' referenced from ABLZMA.OBJ [ILINK32 Error] Error: Unresolved external 'sprintf' referenced from ABWAVPACK.OBJ [ILINK32 Error] Error: Unresolved external 'strncmp' referenced from ABWAVPACK.OBJ [ILINK32 Error] Error: Unresolved external '_ftol' referenced from ABWAVPACK.OBJ AFAICT, all of them are declared correctly, and the _beginthreadex one is actually declared in AbLzma.pas, so it's used by the pure Delphi compile as well. To see it yourself, just download the trunk (or just the "source" and "packages" directories), disable the {$IFDEF BCB} block at the bottom of AbDefine.inc, and try to compile the C++Builder "Abbrevia.cbproj" project.

  • Mysterious constraints problem with SQL Server 2000

    - by Ramon
    Hi all I'm getting the following error from a VB NET web application written in VS 2003, on framework 1.1. The web app is running on Windows Server 2000, IIS 5, and is reading from a SQL server 2000 database running on the same machine. System.Data.ConstraintException: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. at System.Data.DataSet.FailedEnableConstraints() at System.Data.DataSet.EnableConstraints() at System.Data.DataSet.set_EnforceConstraints(Boolean value) at System.Data.DataTable.EndLoadData() at System.Data.Common.DbDataAdapter.FillFromReader(Object data, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords) at System.Data.Common.DbDataAdapter.FillFromCommand(Object data, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet) The problem appears when the web app is under a high load. The system runs fine when volume is low, but when the number of requests becomes high, the system starts rejecting incoming requests with the above exception message. Once the problem appears, very few requests actually make it through and get processed normally, about 2 in every 30. The vast majority of requests fail, until a SQL Server restart or IIS reset is performed. The system then start processing requests normally, and after some time it starts throwing the same error. The error occurs when a data adapter runs the Fill() method against a SELECT statement, to populate a strongly-typed dataset. It appears that the dataset does not like the data it is given and throws this exception. This error occurs on various SELECT statements, acting on different tables. I have regenerated the dataset and checked the relevant constraints, as well as the table from which the data is read. Both the dataset definition and the data in the table are fine. Admittedly, the hardware running both the web app and SQL Server 2000 is seriously outdated, considering the numbers of incoming requests it currently receives. The amount of RAM consumed by SQL Server is dynamically allocated, and at peak times SQL Server can consume up to 2.8 GB out of a total of 3.5 GB on the server. At first I suspected some sort of index or database corruption, but after running DBCC CHECKDB, no errors were found in the database. So now I'm wondering whether this error is a result of the hardware limitations of the system. Is it possible for SQL Server to somehow mess up the data it's supposed to pass to the dataset, resulting in constraint violation due to, say, data type/length mismatch? I tried accessing the RowError messages of the data rows in the retrieved dataset tables but I kept getting empty strings. I know that HasErrors = true for the datatables in question. I have not set the EnableConstraints = false, and I don't want to do that. Thanks in advance. Ray

  • PDF Report generation

    - by IniTech
    EDIT : I completed this project using ABCpdf. For anyone interested, I love this product and their support is A+. Everything I listed as a 'Con' for the HTML - PDF solution was easily doable in ABCpdf. I've been charged with creating a data driven pdf report. After reviewing the plethora of options, I have narrowed it down to 2. I need you all to to help me decide, or offer alternatives I haven't considered. Here are the requirements: 100% Data driven Eventually PDF (a stop in HTML is fine, so long as it is converted) Can be run with multiple sets of data (the layout is always the same, the data is variable) Contains normal analysis-style copy (saved in DB with html markup) Contains tables (data for tables is generated at run-time) Header/Page # on each page Table of Contents .NET (VB or C#) Done quickly Now, because of the fact that the report is going to be generated with multiple sets of data, I don't think a stamped pdf template will work since I won't know how long or how many pages a certain piece of the report could require. So, I think my best options are: Programmatic creation using an iText-like solution. Generate in HTML and convert to PDF using a third-party application (ABCPdf is the tool I have played with so far) Both solutions have their pro's and con's. Programmatic solution: Pros: Flexible Easy page numbering/page header/table of contents Free Cons: Time consuming (to write a layer on top of iText to do what I need and keep maintainable) Since the copy is already stored in the db with html markup, I would have to parse through the data before I place it into the pdf, ensuring I don't have to break the paragraph into chunks so I can apply bold, italic, underline, etc. to specific phrases. This seems like a huge PITA, and I hope I am wrong about that assumption. HTML - PDF Pros: Easy to generate from db (no parsing necessary) Many tools for conversion Uses technology I am already familiar with Built-in "Print Preview" - not a req, but nice Cons: (Edited after project completion. All of my assumptions were incorrect and ABCpdf is awesome) 1. Almost impossible to generate page headers - Not True 2. Very difficult to generate page numbers Not True 3. Nearly impossible to generate table of contents Not True 4. (Cross-browser support isn't a con; Since its internal, I can dictate what browser to use) 5. Conversion tool quirks - may not convert exactly as rendered in browser Not True 6. Overall, I think it would be very hard to format the HTML exactly as I would want it to appear/convert to PDF. Not True That's it - I need the communitys help in deciding which way I should go. I might be wrong about some of my Pro/Con assumptions. If I am, please tell me. All thoughts and suggestions are welcome and appreciated. Thanks

  • What does these FindBug messages show?

    - by Hans Klock
    Not every description from from http://findbugs.sourceforge.net/bugDescriptions.html is clear to me. Sure, I can study the implementation but if somebody is more experienced then me, some explanation and examples would be great. Do you have some examples for UI_INHERITANCE_UNSAFE_GETRESOURCE when this is getting a problem? In BX_UNBOXED_AND_COERCED_FOR_TERNARY_OPERATOR I don't see the problem either. If one type is "bigger" then the other, for example int and float, then the result is float. If its Integer and Float its the wrapper Float too. That's what I expect. Does the GC_UNRELATED_TYPES really help to find errors? Isn't it the job of the compiler to check, if--taking the given example--Foo can't go into a Collection<String>. Does HE_SIGNATURE_DECLARES_HASHING_OF_UNHASHABLE_CLASS mean something like bla(Foo f){hashtable.put(f);}, where ´Foo´ is not hashable? Does FingBugs "see" the subclasses too? NP_GUARANTEED_DEREF_ON_EXCEPTION_PATH is stronger "wrong" then NP_ALWAYS_NULL_EXCEPTION? Why two error cases and with NP_NULL_ON_SOME_PATH_EXCEPTION even one more? Sounds very similar to me. What is an example of SIO_SUPERFLUOUS_INSTANCEOF? Something like foo(String s){if (s intenceof String) .... This does a null check too, but this is not the test here... NN_NAKED_NOTIFY. I my opinion the description is not clear. A change of the state is not necessary. If I use new Object() to wait and notify on I don't change the object state. Or is state the lock-state? I don't get it. SP_SPIN_ON_FIELD. Can this really happen that a compiler will move this outside from a loop? This doesn't make sense to me because from outside a Thread can always change the values. And if the variable is volatile the JVM can't cache the value. So what's the meaning? That is the difference between STCAL_STATIC_CALENDAR_INSTANCE and STCAL_INVOKE_ON_STATIC_CALENDAR_INSTANCE or STCAL_INVOKE_ON_STATIC_DATE_FORMAT_INSTANCE/STCAL_STATIC_SIMPLE_DATE_FORMAT_INSTANCE? Why is XXXX.class in WL_USING_GETCLASS_RATHER_THAN_CLASS_LITERAL better then getClass()? A getClass() in a superclass called from the subclass will always return the Class object from the subclass which is good I think. What exactly does EQ_UNUSUAL do? It should check that the argument is of the same type of the class itself but it does't? Did you ever had problems with breaks? Is there real value with SF_SWITCH_FALLTHROUGH? Sounds to strong for me. No idea what TQ_EXPLICIT_UNKNOWN_SOURCE_VALUE_REACHES_ALWAYS_SINK and TQ_EXPLICIT_UNKNOWN_SOURCE_VALUE_REACHES_NEVER_SINK could be.

  • ANTS CLR and Memory Profiler In Depth Review (Part 2 of 2 &ndash; Memory Profiler)

    - by ToStringTheory
    One of the things that people might not know about me, is my obsession to make my code as efficient as possible. Many people might not realize how much of a task or undertaking that this might be, but it is surely a task as monumental as climbing Mount Everest, except this time it is a challenge for the mind… In trying to make code efficient, there are many different factors that play a part – size of project or solution, tiers, language used, experience and training of the programmer, technologies used, maintainability of the code – the list can go on for quite some time. I spend quite a bit of time when developing trying to determine what is the best way to implement a feature to accomplish the efficiency that I look to achieve. One program that I have recently come to learn about – Red Gate ANTS Performance (CLR) and Memory profiler gives me tools to accomplish that job more efficiently as well. In this review, I am going to cover some of the features of the ANTS memory profiler set by compiling some hideous example code to test against. Notice As a member of the Geeks With Blogs Influencers program, one of the perks is the ability to review products, in exchange for a free license to the program. I have not let this affect my opinions of the product in any way, and Red Gate nor Geeks With Blogs has tried to influence my opinion regarding this product in any way. Introduction – Part 2 In my last post, I reviewed the feature packed Red Gate ANTS Performance Profiler.  Separate from the Red Gate Performance Profiler is the Red Gate ANTS Memory Profiler – a simple, easy to use utility for checking how your application is handling memory management…  A tool that I wish I had had many times in the past.  This post will be focusing on the ANTS Memory Profiler and its tool set. The memory profiler has a large assortment of features just like the Performance Profiler, with the new session looking nearly exactly alike: ANTS Memory Profiler Memory profiling is not something that I have to do very often…  In the past, the few cases I’ve had to find a memory leak in an application I have usually just had to trace the code of the operations being performed to look for oddities…  Sadly, I have come across more undisposed/non-using’ed IDisposable objects, usually from ADO.Net than I would like to ever see.  Support is not fun, however using ANTS Memory Profiler makes this task easier.  For this round of testing, I am going to use the same code from my previous example, using the WPF application. This time, I will choose the ‘Profile Memory’ option from the ANTS menu in Visual Studio, which launches the solution in its currently configured state/start-up project, and then launches the ANTS Memory Profiler to help.  It prepopulates all of the fields with the current project information, and all I have to do is select the ‘Start Profiling’ option. When the window comes up, it is actually quite barren, just giving ideas on how to work the profiler.  You start by getting to the point in your application that you want to profile, and then taking a ‘Memory Snapshot’.  This performs a full garbage collection, and snapshots the managed heap.  Using the same WPF app as before, I will go ahead and take a snapshot now. As you can see, ANTS is already giving me lots of information regarding the snapshot, however this is just a snapshot.  The whole point of the profiler is to perform an action, usually one where a memory problem is being noticed, and then take another snapshot and perform a diff between them to see what has changed.  I am going to go ahead and generate 5000 primes, and then take another snapshot: As you can see, ANTS is already giving me a lot of new information about this snapshot compared to the last.  Information such as difference in memory usage, fragmentation, class usage, etc…  If you take more snapshots, you can use the dropdown at the top to set your actual comparison snapshots. If you beneath the timeline, you will see a breadcrumb trail showing how best to approach profiling memory using ANTS.  When you first do the comparison, you start on the Summary screen.  You can either use the charts at the bottom, or switch to the class list screen to get to the next step.  Here is the class list screen: As you can see, it lists information about all of the instances between the snapshots, as well as at the bottom giving you a way to filter by telling ANTS what your problem is.  I am going to go ahead and select the Int16[] to look at the Instance Categorizer Using the instance categorizer, you can travel backwards to see where all of the instances are coming from.  It may be hard to see in this image, but hopefully the lightbox (click on it) will help: I can see that all of these instances are rooted to the application through the UI TextBlock control.  This image will probably be even harder to see, however using the ‘Instance Retention Graph’, you can trace an objects memory inheritance up the chain to see its roots as well.  This is a simple example, as this is simply a known element.  Usually you would be profiling an actual problem, and comparing those differences.  I know in the past, I have spotted a problem where a new context was created per page load, and it was rooted into the application through an event.  As the application began to grow, performance and reliability problems started to emerge.  A tool like this would have been a great way to identify the problem quickly. Overview Overall, I think that the Red Gate ANTS Memory Profiler is a great utility for debugging those pesky leaks.  3 Biggest Pros: Easy to use interface with lots of options for configuring profiling session Intuitive and helpful interface for drilling down from summary, to instance, to root graphs ANTS provides an API for controlling the profiler. Not many options, but still helpful. 2 Biggest Cons: Inability to automatically snapshot the memory by interval Lack of complete integration with Visual Studio via an extension panel Ratings Ease of Use (9/10) – I really do believe that they have brought simplicity to the once difficult task of memory profiling.  I especially liked how it stepped you further into the drilldown by directing you towards the best options. Effectiveness (10/10) – I believe that the profiler does EXACTLY what it purports to do.  Features (7/10) – A really great set of features all around in the application, however, I would like to see some ability for automatically triggering snapshots based on intervals or framework level items such as events. Customer Service (10/10) – My entire experience with Red Gate personnel has been nothing but good.  their people are friendly, helpful, and happy! UI / UX (9/10) – The interface is very easy to get around, and all of the options are easy to find.  With a little bit of poking around, you’ll be optimizing Hello World in no time flat! Overall (9/10) – Overall, I am happy with the Memory Profiler and its features, as well as with the service I received when working with the Red Gate personnel.  Thank you for reading up to here, or skipping ahead – I told you it would be shorter!  Please, if you do try the product, drop me a message and let me know what you think!  I would love to hear any opinions you may have on the product.

  • Points in CSS specificity

    - by Sam
    Researching specificity I stumbled upon this blog - http://www.htmldog.com/guides/cssadvanced/specificity/ It states that specificity is a point-scoring system for CSS. It tells us that elements are worth 1 point, classes are worth 10 points and IDs are worth 100 points. It also goes on top say that these points are totaled and the overall amount is that selector's specificity. For example: body = 1 point body .wrapper = 11 points body .wrapper #container = 111 points So, using these points surely the following CSS and HTML will result in the text being blue: CSS: #a { color: red; } .a .b .c .d .e .f .g .h .i .j .k .l .m .n .o { color: blue; } HTML: <div class="a"> <div class="b"> <div class="c"> <div class="d"> <div class="e"> <div class="f"> <div class="g"> <div class="h"> <div class="i"> <div class="j"> <div class="k"> <div class="l"> <div class="m"> <div class="n"> <div class="o" id="a"> This should be blue. </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> RESULT: http://jsfiddle.net/hkqCF/ Why is the text red when 15 classes would equal 150 points compared to 1 ID which equals 100 points?

  • Smooth animation on a persistently refreshing canvas

    - by Neurofluxation
    Yo everyone! I have been working on an Isometric Tile Game Engine in HTML5/Canvas for a little while now and I have a complete working game. Earlier today I looked back over my code and thought: "hmm, let's try to get this animated smoothly..." And since then, that is all I have tried to do. The problem I would like the character to actually "slide" from tile to tile - but the canvas redrawing doesn't allow this - does anyone have any ideas....? Code and fiddle below... Fiddle with it! http://jsfiddle.net/neuroflux/n7VAu/ <html> <head> <title>tileEngine - Isometric</title> <style type="text/css"> * { margin: 0px; padding: 0px; font-family: arial, helvetica, sans-serif; font-size: 12px; cursor: default; } </style> <script type="text/javascript"> var map = Array( //land [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]], [[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0],[0,0,0]] ); var tileDict = Array("http://www.wikiword.co.uk/release-candidate/canvas/tileEngine/land.png"); var charDict = Array("http://www.wikiword.co.uk/release-candidate/canvas/tileEngine/mario.png"); var objectDict = Array("http://www.wikiword.co.uk/release-candidate/canvas/tileEngine/rock.png"); //last is one more var objectImg = new Array(); var charImg = new Array(); var tileImg = new Array(); var loaded = 0; var loadTimer; var ymouse; var xmouse; var eventUpdate = 0; var playerX = 0; var playerY = 0; function loadImg(){ //preload images and calculate the total loading time for(var i=0;i<tileDict.length;i++){ tileImg[i] = new Image(); tileImg[i].src = tileDict[i]; tileImg[i].onload = function(){ loaded++; } } i = 0; for(var i=0;i<charDict.length;i++){ charImg[i] = new Image(); charImg[i].src = charDict[i]; charImg[i].onload = function(){ loaded++; } } i = 0; for(var i=0;i<objectDict.length;i++){ objectImg[i] = new Image(); objectImg[i].src = objectDict[i]; objectImg[i].onload = function(){ loaded++; } } } function checkKeycode(event) { //key pressed var keycode; if(event == null) { keyCode = window.event.keyCode; } else { keyCode = event.keyCode; } switch(keyCode) { case 38: //left if(!map[playerX-1][playerY][1] > 0){ playerX--; } break; case 40: //right if(!map[playerX+1][playerY][1] > 0){ playerX++; } break; case 39: //up if(!map[playerX][playerY-1][1] > 0){ playerY--; } break; case 37: //down if(!map[playerX][playerY+1][1] > 0){ playerY++; } break; default: break; } } function loadAll(){ //load the game if(loaded == tileDict.length + charDict.length + objectDict.length){ clearInterval(loadTimer); loadTimer = setInterval(gameUpdate,100); } } function drawMap(){ //draw the map (in intervals) var tileH = 25; var tileW = 50; mapX = 80; mapY = 10; for(i=0;i<map.length;i++){ for(j=0;j<map[i].length;j++){ var drawTile= map[i][j][0]; var xpos = (i-j)*tileH + mapX*4.5; var ypos = (i+j)*tileH/2+ mapY*3.0; ctx.drawImage(tileImg[drawTile],xpos,ypos); if(i == playerX && j == playerY){ you = ctx.drawImage(charImg[0],xpos,ypos-(charImg[0].height/2)); } } } } function init(){ //initialise the main functions and even handlers ctx = document.getElementById('main').getContext('2d'); loadImg(); loadTimer = setInterval(loadAll,10); document.onkeydown = checkKeycode; } function gameUpdate() { //update the game, clear canvas etc ctx.clearRect(0,0,904,460); ctx.fillStyle = "rgba(255, 255, 255, 1.0)"; //assign color drawMap(); } </script> </head> <body align="center" style="text-align: center;" onload="init()"> <canvas id="main" width="904" height="465"> <h1 style="color: white; font-size: 24px;">I'll be damned, there be no HTML5 &amp; canvas support on this 'ere electronic machine!<sub>This game, jus' plain ol' won't work!</sub></h1> </canvas> </body> </html>

  • How to match multiple substrings in jQuery combobox autocomplete

    - by John R
    I found more than a couple examples of this with a plain jquery autocomplete but not in a way that will work with the autocomplete included in the combobox code from the demo because the structure of the code is structured so differently. I want to match every item that has all of the search tokens anywhere in any word. I don't need to match the start of any word, any part of it is fine. I don't care if the search strings are highlighted in the autocomplete list if that makes things too complicated. Desired search/result combos: (please excuse the spacing) "fi th" "fi rst second th ird" "rs on" "fi rs t sec on d third" "ec rd" "first s ec ond thi rd" but not limited to any max/min length or number of tokens. EDIT I figured part of it out using the code structure from the other autocorrect I had working. source: function( requestObj, responseFunc ) { var matchArry = $("select > option").map(function(){return this.innerHTML;}).get(); var srchTerms = $.trim(requestObj.term).split(/\s+/); // For each search term, remove non-matches $.each (srchTerms, function (J, term) { var regX = new RegExp (term, "i"); matchArry = $.map (matchArry, function (item) { if( regX.test(item) ){ return{ label: item, value: item, option: HTMLOptionElement } ? item :null; } } ); }); // Return the match results responseFunc (matchArry); }, and select: function( event, ui ) { ui.item.option.selected = true; self._trigger( "selected", event, { item: ui.item.option }); $("destination").val(ui.item.value); // I added this line }, but I can't get both multiple words AND being able to click to select working at the same time. If I remove the } ? item :null; on the return in the map function I can click to select an item. If I leave it I can type multiple words, but I can't click any of the items... Is that the problem or the option: this? I've tried replacing it with HTMLOptionElement and null and I'm stuck. I am able to set the value of another field with ui.item.value within the select label but that doesn't put the value in the search box or close the dropdown menu. Fiddle of current code: http://jsfiddle.net/eY3hM/

  • "Access violation reading location" while accessing a global vector..

    - by djzmo
    Hello there, -- First of all, I don't know whether the vector can be called as a "global vector" if I declared it under a namespace, but not in a class or function. -- I'm now writing a simple Irrlicht (http://irrlicht.sourceforge.net) wrapper for my game to make things simpler and easier, but recently I got an "Access violation reading location" error when trying to push_back a vector declared in the global scope. Here is my code so far: irrwrap.cpp: namespace irrw { //......... IrrlichtDevice *device; IVideoDriver *driver; irr::core::array<irr::video::ITexture*> TextureCollector; vector<int> TextureConnector; //......... } //.............. void irrInit(int iGraphicsDriver, int iWindowWidth, int iWindowHeight, int iScreenDepth, bool bFullScreen) { E_DRIVER_TYPE drvT; if(iGraphicsDriver == GD_SOFTWARE) drvT = EDT_SOFTWARE; else if(iGraphicsDriver == GD_D3D8) drvT = EDT_DIRECT3D8; else if(iGraphicsDriver == GD_D3D9) drvT = EDT_DIRECT3D9; else if(iGraphicsDriver == GD_OPENGL) drvT = EDT_OPENGL; //.............. irrw::device = createDevice(drvT, dimension2d<u32>(iWindowWidth, iWindowHeight), iScreenDepth, bFullScreen); irrw::driver = irrw::device->getVideoDriver(); //.................. } void irrLoadImage(irr::core::stringc szFileName, int iID, int iTextureFlag) { //........ irrw::TextureCollector.push_back(irrw::driver->getTexture(szFileName)); // the call stack pointed to this line irrw::TextureConnector.push_back(iID); } main.cpp: //......... INT WINAPI WinMain(HINSTANCE hInst, HINSTANCE, LPSTR strCmdLine, INT) { //......... irrInit(GD_OPENGL, 800, 600, 16, false); irrLoadImage("picture.jpg", 100, 1); //......... } and the error: Unhandled exception at 0x692804d6 in Game.exe: 0xC0000005: Access violation reading location 0x00000558. Now I really got no idea on how to fix the problem. Any kind of help would be appreciated :) Here are some prototypes: virtual ITexture* getTexture(const io::path& filename) = 0; typedef core::string<fschar_t> path; // under 'io' namespace typedef char fschar_t; typedef string<c8> stringc; typedef char c8; Just FYI, I am using MSVC++ 2008 EE.

  • Deriving from a component and implementing IDisposable properly

    - by PaulH
    I have a Visual Studio 2008 C# .NET 2.0 CF project with an abstract class derived from Component. From that class, I derive several concrete classes (as in my example below). But, when I go to exit my Form, though the Form's Dispose() member is called and components.Dispose() is called, my components are never disposed. Can anybody suggest how I can fix this design? public abstract class SomeDisposableComponentBase : Component { private System.ComponentModel.IContainer components; protected SomeDisposableComponentBase() { Initializecomponent(); } protected SomeDisposableComponentBase(IContainer container) { container.Add(this); Initializecomponent(); } private void InitializeComponent() { components = new System.ComponentModel.Container(); } protected abstract void Foo(); #region IDisposable Members bool disposed_; /// Warning 60 CA1063 : Microsoft.Design : Ensure that 'SomeDisposableComponentBase.Dispose()' is declared as public and sealed.* public void Dispose() { // never called Dispose(true); GC.SuppressFinalize(this); } protected virtual void Dispose(bool disposing) { // never called if (!disposed_) { if (disposing && (components != null)) { components.Dispose(); } disposed_ = true; } base.Dispose(disposing); } #endregion } public SomeDisposableComponent : SomeDisposableComponentBase { public SomeDisposableComponent() : base() { } public SomeDisposableComponent(IContainer container) : base(container) { } protected override void Foo() { // Do something... } protected override void Dispose(bool disposing) { // never called base.Dispose(disposing); } } public partial class my_form : Form { private SomeDisposableComponentBase d_; public my_form() { InitializeComponent(); if (null == components) components = new System.ComponentModel.Container(); d_ = new SomeDisposableComponent(components); } /// exit button clicked private void Exit_Click(object sender, EventArgs e) { this.Close(); } /// from the my_form.designer.cs protected override void Dispose(bool disposing) { if (disposing && (components != null)) { // this function is executed as expected when the form is closed components.Dispose(); } base.Dispose(disposing); } } *I note that FX-Cop is giving me a hint here. But, if I try to declare that function as sealed, I get the error: error CS0238: 'SomeDisposableComponentBase.Dispose()' cannot be sealed because it is not an override Declaring that function an override leads to: 'SomeDisposableComponentBase.Dispose()': cannot override inherited member 'System.ComponentModel.Component.Dispose()' because it is not marked virtual, abstract, or override Thanks, PaulH
