• Is there an event that raises after a View/PartialView executes in ASP.NET MVC 2 RC2?

  - by sabanito

  I have the following problem: We have an ASP.NET MVC 2 RC 2 application that programmatically impersonates an AD Account that the user specifies at logon. This account is used to access the DB. At first we had the impersonating code in the begin_request and we were undoing the impersonation at the end_request, but when we tried to use IIS 7.5 in integrated mode, we learned that it's not possible to impersonate in the Global.asax so we tried different things. We have succesfully moved our code from the BeginRequest to the ActionExecuting event and the EndRequest to the ResultExecuted, and now, about 80% of our code works. We've just discovered that since we're passing the Entity Framework objects as models for our views, there's this remaining 20% that won't work because some Navigation Properties are not loaded when the view begins it's execution, so we're getting connection exceptions from Sql Server. Is there any event or method that executes AFTER the view, so we can undo the impersonation in it? We thought ResultExecuted will do just that, but it doesn't. We've been told that passing the plain Entities into the view as models is not a good idea, but we have A LOT of views that may have this problem and there's not automated way to know it. If some of you could explain why it's not a good idea, maybe we can convince the team to fix it!

• jquery .submit live click runs more than once

  - by fxuser

  I use the following code to run my form ajax requests but when i use the live selector on a button i can see the ajax response fire 1 time, then if i re-try it 2 times, 3 times, 4 times and so on... I use .live because i also have a feature to add a post and that appears instantly so the user can remove it without refreshing the page... Then this leads to the above problem... using .click could solve this but it's not the ideal solution i'm looking for... jQuery.fn.postAjax = function(success_callback, show_confirm) { this.submit(function(e) { e.preventDefault(); if (show_confirm == true) { if (confirm('Are you sure you want to delete this item? You can\'t undo this.')) { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } } else { $.post(this.action, $(this).serialize(), $.proxy(success_callback, this)); } return false; }) return this; }; $(document).ready(function() { $(".delete_button").live('click', function() { $(this).parent().postAjax(function(data) { if (data.error == true) { } else { } }, true); }); });? EDIT: temporary solution is to change this.submit(function(e) { to this.unbind('submit').bind('submit',function(e) { the problem is how can i protect it for real because people who know how to use Firebug or the same tool on other browsers can easily alter my Javascript code and re-create the problem

• Business entity: private instance VS single instance

  - by taoufik

  Suppose my WinForms application has a business entity Order, the entity is used in multiple views, each view handles a different domain or use-case in the application. As an example, one managing orders, the other one digging into one order and displaying additional data. If I'd use nHibernate (or any other ORM) and use one session/dataContext per view (or per db action), I'd end up getting two different instances for the same Order (let's say orderId = 1). Although functionally the same entity, they are technically two different instances. Yes, I could implement Equals/GetHashcode to make them "seem" the same. Why would you go for a single instance per entity vs private instances per view or per use-case? Having single instances has the advantage of sharing INotifyPropertyChanged events, and sharing additional (non-persistent) data. Having a private instance in each view would give you the flexibility of the undo functionality on a view level. In the example above, I'd allow the user to change order details, and give them the flexibility to not save the change. Here, synchronisation between the view/use-case happens on a data persistence level. What would your argument be?

• using checkbox as radio button

  - by ash34

  Hi, I am looking for a way for users to select one of the two options (strength or weakness) for a list of qualities. for eg: strength weakness not applicable 1. Communication 2. Punctuality ... Radio button lets me select either a strength or weakness. However, I want the user to check only those qualities that apply and if a user accidentally selects a quality there is no way to undo the selection for a radio button unless there is a third radio button called not applicable or have the user re-enter the page. I was wondering if there is a way to be able to get the flexibility of a checkbox (check / uncheck) in addition to disabling or enabling the other checkbox when one of them is checked or unchecked instead of using three radio buttons. I don't think I have seen this behavior before so wondering if there is a more elegant way of doing this. I am open to other ideas to get the same functionality. Using a checkbox as radio button was just a thought. thanks much.

• Time Machine for Windows?

  - by Blub

  Finally got convinced to start using some kind of version control for my code instead of zipping down a copy of the project at the end of each day. Downloaded Tortoise SVN and used it to create a repository localy on my hdd. I've been using it for 2 days now but I have to say that using it is actually more hassle than just copying the project manually in explorer. Sure, you only store incremental changes but with the cheap disks of today I can't really say that's an argument when you only have small projects. I haven't realy found a quick way to browse the older versions of my files eighter. What I want is an infinite undo that is completely transparent while I code, if I save the file I want a backup. I don't want to check out, check in and don't even get me started on moving files. I haven't tried Time Machine for OS X but it looks like it's exactly what I'm looking for. Does such a program exist for windows? Preferably free and with some kind of tagging-system so I can tag a timestamp when the project is working etc. Maybe should add that I mostly work alone on a single computer. Update: Some of you asked why I want backup. Since I work alone it's mostly to allow me to quickly hack up a solution without worrying that something will screw up.

• Is there a way to make changes to toggles in my .emacs file apply without re-starting Emacs?

  - by Vivi

  I want to be able to make the changes to my .emacs file without having to reload Emacs. I found three questions which sort of answer what I am asking (you can find them here, here and here), but the problem is that the change I have just made is to a toggle, and as the comments to two of the answers (a1, a2) to those questions explain, the solutions given there (such as M-x reload-file or M-x eval-buffer) don't apply to toggles. I imagine there is a way of toggling the variable again with a command, but if there is a way to reload the whole .emacs and have the all the toggles re-evaluated without having to specify them, I would prefer. In any case, I would also appreciate if someone told me how to toggle the value of a variable so that if I just changed one toggle I can do it with a command rather than re-start Emacs just for that (I am new to Emacs). I don't know how useful this information is, but the change I applied was the following (which I got from this answer to another question): (setq skeleton-pair t) (setq skeleton-pair-on-word t) (global-set-key (kbd "[") 'skeleton-pair-insert-maybe) (global-set-key (kbd "(") 'skeleton-pair-insert-maybe) (global-set-key (kbd "{") 'skeleton-pair-insert-maybe) (global-set-key (kbd "<") 'skeleton-pair-insert-maybe) Edit: I included the above in .emacs and reloaded Emacs, so that the changes took effect. Then I commented all of it out and tried M-x load-file. This doesn't work. The suggestion below (C-x C-e by PP works if I am using it to evaluate the toggle first time, but not when I want to undo it). I would like something that would evaluate the commenting out, if such thing exists... Thanks :)

• How do I test database-related code with NUnit?

  - by Michael Haren

  I want to write unit tests with NUnit that hit the database. I'd like to have the database in a consistent state for each test. I thought transactions would allow me to "undo" each test so I searched around and found several articles from 2004-05 on the topic: http://weblogs.asp.net/rosherove/archive/2004/07/12/180189.aspx http://weblogs.asp.net/rosherove/archive/2004/10/05/238201.aspx http://davidhayden.com/blog/dave/archive/2004/07/12/365.aspx http://haacked.com/archive/2005/12/28/11377.aspx These seem to resolve around implementing a custom attribute for NUnit which builds in the ability to rollback DB operations after each test executes. That's great but... Does this functionality exists somewhere in NUnit natively? Has this technique been improved upon in the last 4 years? Is this still the best way to test database-related code? Edit: it's not that I want to test my DAL specifically, it's more that I want to test pieces of my code that interact with the database. For these tests to be "no-touch" and repeatable, it'd be awesome if I could reset the database after each one. Further, I want to ease this into an existing project that has no testing place at the moment. For that reason, I can't practically script up a database and data from scratch for each test.

• Can I stop the dbml designer from adding a connection string to the dbml file?

  - by drs9222

  We have a custom function AppSettings.GetConnectionString() which is always called to determine the connection string that should be used. How this function works is unimportant to the discussion. It suffices to say that it returns a connection string and I have to use it. I want my LINQ to SQL DataContext to use this so I removed all connection string informatin from the dbml file and created a partial class with a default constructor like this: public partial class SampleDataContext { public SampleDataContext() : base(AppSettings.GetConnectionString()) { } } This works fine until I use the designer to drag and drop a table into the diagram. The act of dragging a table into the diagram will do several unwanted things: A settings file will be created A app.config file will be created My dbml file will have the connection string embedded in it All of this is done before I even save the file! When I save the diagram the designer file is recreated and it will contain its own default constructor which uses the wrong connection string. Of course this means my DataContext now has two default constructors and I can't build anymore! I can undo all of these bad things but it is annoying. I have to manually remove the connection string and the new files after each change! Is there anyway I can stop the designer from making these changes without asking? EDIT The requirement to use the AppSettings.GetConnectionString() method was imposed on me rather late in the game. I used to use something very similar to what it generates for me. There are quite a few places that call the default constructor. I am aware that change them all to create the data context in another way (using a different constructor, static method, factory, ect..). That kind of change would only be slightly annoying since it would only have to be done once. However, I feel, that it is sidestepping the real issue. The dbml file and configuration files would still contain an incorrect, if unused, connection string which at best could confuse other developers.

• show image in a CGContextRef

  - by Ishu

  What i am doing, i downloded a code from calender now i want to show images on its tiles(for date). What i am trying shows in code - (void)drawTextInContext:(CGContextRef)ctx { CGContextSaveGState(ctx); CGFloat width = self.bounds.size.width; CGFloat height = self.bounds.size.height; CGFloat numberFontSize = floorf(0.3f * width); CGContextSetFillColorWithColor(ctx, kDarkCharcoalColor); CGContextSetTextDrawingMode(ctx, kCGTextClip); for (NSInteger i = 0; i < [self.text length]; i++) { NSString *letter = [self.text substringWithRange:NSMakeRange(i, 1)]; CGSize letterSize = [letter sizeWithFont:[UIFont boldSystemFontOfSize:numberFontSize]]; CGContextSaveGState(ctx); // I will need to undo this clip after the letter's gradient has been drawn [letter drawAtPoint:CGPointMake(4.0f+(letterSize.width*i), 0.0f) withFont:[UIFont boldSystemFontOfSize:numberFontSize]]; if ([self.date isToday]) { CGContextSetFillColorWithColor(ctx, kWhiteColor); CGContextFillRect(ctx, self.bounds); } else { // CGContextDrawLinearGradient(ctx, TextFillGradient, CGPointMake(0,0), CGPointMake(0, height/3), kCGGradientDrawsAfterEndLocation); CGDataProviderRef dataProvider = CGDataProviderCreateWithFilename("left-arrow.png"); CGImageRef image = CGImageCreateWithPNGDataProvider(dataProvider, NULL, NO, kCGRenderingIntentDefault); //UIImage* image = [UIImage imageNamed:@"left-arrow.png"]; //CGImageRef imageRef = image.CGImage; CGContextDrawImage(ctx, CGRectMake(8.0f+(letterSize.width*i), 0.0f, 5, 5), image); //im.image=[UIImage imageNamed:@"left-arrow.png"]; } CGContextRestoreGState(ctx); // get rid of the clip for the current letter } CGContextRestoreGState(ctx); } In else condition i want to show images on the tile so for that i am converting image objects in the CGContextDrawImage. Please help me. I am not sure this would be done in same manner or in other manner please suggest your way to do this. Thanx a lot.

• How to make Solution Explorer behave after clearing search?

  - by stijn

  I currently have a VS installation with no extensions to see how that works out. For navigation that means making heavy use of Ctrl+; aka Search Solution Explorer. While the search itself is ok, it has one major drawback for me that makes it a pain to use for me (both with keyboard and mouse): Solution with two projects, one collapsed, one opened: Use Ctrl+; and start typing until match found from collapsed project What I want now is to simply clear the search and return to the previous view. Seems like a pretty standard requirement, no? But there seems to be no such functionality built in. Problem with the current commands that come close (pressing Esc, clicking Back or Home buttons in Solution Explorer Toolbar) is all the same: they have the extremely annoying behaviour that they insist on suddenly uncollapsing the previously collapsed project and track the match found! (Btw the Track Active Item in Solution Explorer option is turned of in the options). This makes no sense from a UX point of view? You select some kind of 'undo' command, the search box clears which is expected, but then suddenly there's an item visible from a previous search: So if the collapsed project has like 50 items in it, solution explorer is now useless visually since it litters the screen with stuff you don't want to see, and worse you have to manually collapse the project again to return to the previous view. Is there a way around this? I thought maybe keyboard shortcuts for Back/Home would be different, but the commands do not seem to be registered. I looked into EnvDTE80.DTE2.ToolWindows.SolutionExplorer but it has no properties/methods that have anything to do with this issue. And somewhere in the tree there is a Microsoft.VisualStudio.PlatformUI.SolutionPivotNavigator which is probably the class responsible for this behaviour, but I have no idea how to access it?

• NSTableView selection & highlights

  - by Christian

  I have a NSTableView as a very central part of my Application and want it to integrate more with the rest of it. It has only one column (it's a list) and I draw all Cells (normal NSTextFieldCells) myself. The first problem is the highlighting. I draw the highlight myself and want to get rid of the blue background. I now fill the whole cell with the original background color to hide the blue background, but this looks bad when dragging the cell around. I tried overriding highlight:withFrame:inView: and highlightColorWithFrame:inView: of NSCell but nothing happened. How can I disable automatic highlighting? I also want all rows/cells to be deselected when I click somewhere outside my NSTableView. Since the background / highlight of the selected cell turns gray there must be an event for this, but I can't find it. I let my cells expand on a double click and may need to undo this. So getting rid of the gray highlight is not enough. EDIT: I add a subview to the NSTableView when a cell gets double clicked and then resignFirstResponder of the NSTableView gets called. I tried this: - (BOOL)resignFirstResponder { if (![[self subviews] containsObject:[[self window] firstResponder]]) { [self deselectAll:self]; ... } return YES; } Besides that it's not working I would need to implement this method for all objects in the view hierarchy. Is there an other solution to find out when the first responder leaves a certain view hierarchy?

• Changing url of background image

  - by João Pedro

  I'm doing this interface where I have a lot of buttons that are just a li with a background image like this #menu ul.icons li.nove { background-image:url(images/edit-menu/icons/undo.png); background-size:contain; display:block; margin-top:29px; } <ul class="icons"> <li class="um"></li> <li class="dois"></li> <li class="tres"></li> <li class="quatro"></li> <li class="cinco"></li> <li class="seis"></li> <li class="sete"></li> <li class="oito"></li> <li class="nove"></li> <li class="dez"></li> </ul> I need to create a code where I change the background image of the button when the user clicks it, to show that button its activated, I just need to change url(images/edit-menu/icons/ to url(images/edit-menu/select/ and keep the same filename. I need a way to do this dynamically so I won't have to do it for each of the 10 buttons. Hope I was clear, thanks in advance

• How might one cope with the ambiguous value produced by GetDllDirectory?

  - by Integer Poet

  GetDllDirectory produces an ambiguous value. When the string this call produces is empty, it means one of the following: nobody has called SetDllDirectory somebody passed NULL to SetDllDirectory somebody passed an empty string to SetDllDirectory The first two cases are equivalent for my purposes, but the third case is a problem. If I want to write save/restore code (call GetDllDirectory to save the "old" value, SetDllDirectory to set a "new" value temporarily, and later SetDllDirectory again to restore the "old" value), I run the risk of reversing some other programmer's intent. If the other programmer intended for the current working directory to be in the DLL search order (in other words, one of the first two bullets is true), and I pass an empty string to SetDllDirectory, I will be taking the current working directory out of the DLL search order, reversing the other programmer's intent. Can anyone suggest an approach to eliminate or work around this ambiguity? P.S. I know having the current working directory in the DLL search order could be interpreted as a security hole. Nevertheless, it is the default behavior, and my code is not in a position to undo that; my code needs to be compatible with the expectations of all potential callers, many of which are large and old and beyond my control.

• PHP OO vs Procedure with AJAX

  - by vener

  I currently have a AJAX heavy(almost everything) intranet webapp for a business. It is highly modularized(components and modules ala Joomla), with plenty of folders and files. ~ 80-100 different viewing pages (each very unique in it's own sense) on last count and will likely to increase in the near future. I based around the design around commands and screens, the client request a command and sends the required data and receives the data that is displayed via javascript on the screen. That said, there are generally two types of files, a display files with html, javascript, and a little php for templating. And also a php backend file with a single switch statement with actions such as, save, update and delete and maybe other function. There is very little code reuse. Recently, I have been adding an server sided undo function that requires me to reuse some code. So, I took the chance to try out OOP but I notice that some functions are so simple, that creating a class, retrieving all the data then update all the related rows on the database seems like overkill for a simple action as speed is quite critical. Also I noticed there is only one class in an entire file. So, what if the entire php is a class. So, between creating a class and methods, and using global variables and functions. Which is faster?

• PHP include taking too long

  - by wxiiir

  I have a php file with around 100mb which is full of arrays (only arrays). I've made a script that includes this file (for processing), first it exhausted the default Xampp 128mb memory limit, i've raised it to 1024mb but it just takes forever and doesn't do anything. I'm sure the problem is being created by the sheer size of the file because i've tried removing all lines of code and just leaving the include and an echo for me to know when it finishes executing, and it does the same thing (which is taking forever), i've also tried to run the 100mb file in separate and same thing again. A 10mb file is taking forever as well but a similar 1mb file is almost instantly read and executed so the problem must be more than just the file size. I was avoiding using c++ for a simple project as this and would rather not to as php is easier for me and the task that will be executed doesn't need to benefit from the added speed that it would have if it had been done in c++ but if i have no luck in solving this problem i guess i'll have to. EDIT Reasons for not using a database: 1-Whoever made it didn't used a database and it will be pretty hard to store this in an organized database if i'm not able to do something with it first, like just reading it, copying parts from it or putting in memory or something. 2-I don't have experience working with databases as pretty much all stuff i've ever done in php didn't needed large amounts of stored data, 50kb at best, if i was thinking about a big project or huge chunks of data as this one, i definitely would, but i didn't made this mess to start with and now i have to undo it. 3-The logic for having to store a small portion of data like 10mb in hard drive when now every computer has pretty much enough ram to fit the whole OS in it is pretty much incomprehensible unless someone gives a good explanation about it, if i had to access a lot of said files simultaneously i would understand but like i said, this is a simple project, this is the only file that will be accessed at a given time this isn't even to make some kind of website, it's to run a few times and be done with it.

• How to properly manage a complex DB structure?

  - by errr

  Let's say you have several systems using the same DB - each uses several schemes (sometimes same as the other). This structure of these schemes is somewhat very big and complicated. Now, how could you possibly manage such scheme structure? Obviously using some sort of "configuration" - the simplest would be SQL scripts, but a more reasonable solution would be XMLs which can be easily converted into SQL, or some other readable solution (for example, JPA's XMLs or Annotations). This solution though, causes a problem where you can't really tell if your configuration matches the structure of the DB schemes exactly. You can't say if those two are synchronized. Why wouldn't they? Well, in such big structure there are going to be many changes, and you won't always remember to save/commit your configuration after you've altered the schemes, or maybe you did save/commit it, but eventually didn't altered anything in the schemes and forgot to undo the changes to the configuration. More than that, another problem (not caused by the configuration, but isn't addressed by it either) is versioning. I don't see any good way of managing the DB schemes versions (say our last alteration makes 3 systems crash - not good, how to "rollback"?). And thoughts? thx.

• Aggregate SharePoint Event/Items into your Calendar view using Calendar Overlay

  - by eJugnoo

  One of the most common features I have seen in common use for SharePoint (prior to 2010) in Intranet environments for Team site is Calendar’s. Not only the Calendar list type, but also the ability to add a Calendar view to any list that has the desired columns to construct a Calendar – such as Start, End, Title etc. While this was all great for a single site/calendar, the problem of having to track numerous calendar’s remained. With introduction of Outlook 2007 bi-directional integration with SharePoint, and particularly the ability of Outlook to overlay calendar helped bridge the gap. Now one could connect to number of team sites, and setup Calendar overlays in Outlook using varying colours, to easily identify event source and yet benefit from the plotting of events on single Calendar view. This was all good, but each user in your Enterprise was supposed to setup in a “pull” fashion. This is good for flexibility, not so good when you need to “push” consistency and productivity (re-use). So, what was missing on SharePoint is the ability to have server-side overlay’s that everyone can see – in a single place, aggregating multiple sources. Until SharePoint 2010 arrived! Calendars Overlay in SharePoint 2010 There are Calendar lists and Calendar views. View can be created for almost all lists, as far as you have desired column’s in a list like Start, End, Title etc. to be able to describe and plot an item in a Calendar format. In SharePoint 2010, create a new Calendar list. Go to Calendar ribbon tab, and click Calendar Overlay. You get the screen with list of existing Overlay’s associated with current Calendar (list – in our case). Click on “New Calendar”… Notice the breadcrumb! You are adding Overlay to existing list (Team Calendar – in our case). You have choice of “pulling” Calendar info from an existing Calendar (list/view) in SharePoint or even from Exchange! Set standard info like a name, description and decide the colour you want for the items in aggregated Calendar overlay. Select the source site/list/view, anywhere in farm. When you select Exchange as source of Calendar, you get option to add OWA and Exchange Web Service url. I will cover details of connecting with Exchange in another post, and focus on Overlay’s with SharePoint for this one. Once you have added a new Calendar overlay to existing Calendar veiw, you get something like below for Day view, Week view, and Month view respectively Notice the Overlay colours: Now, if you decide to connect this Calendar to Outlook to sync the items, it will only sync items from main view, and not from Overlay source. So such Overlay of calendar’s is server-side aggregation only. That increases my curiosity, so I try adding the Calendar list view as a web-part on a new page. As you see, this instance of view didn’t include item from source that we had added to default Calendar view. This is – probably – due to the fact that this is a new web-part view for the page. If you want to add overlay to this one, you have to redo that from Ribbon. This also means, subject to purpose and context you get the flexibility to decide what overlay is suited. Also you can only add 10 Overlay’s to an existing view instance. Conclusion Calendar Overlay is clearly a very useful feature that fills a gap of not being able to aggregate information from multiple sources into a Calendar view within context of current items. Source of items can be existing SharePoint calendar views on any site, or even Exchange (via OWA/Exchange web services). List type for source doesn’t matter, it just need a Calendar view type available. You can have 10 overlays. Overlays are for the specific view only, and are server-side only – which means they do not get synced in Outlook. While you can drag-drop current list items, you cannot edit overlay items as they are read-only within scope of current Calendar view. You can of course click on source Overlay item to edit at the source. I’d like to hear, how you think Overlay’s will help you in your case, or how you are already using them... Enjoy SharePoint! --Sharad

• Windows Presentation Foundation 4.5 Cookbook Review

  - by Ricardo Peres

  As promised, here’s my review of Windows Presentation Foundation 4.5 Cookbook, that Packt Publishing kindly made available to me. It is an introductory book, targeted at WPF newcomers or users with few experience, following the typical recipes or cookbook style. Like all Packt Publishing books on development, each recipe comes with sample code that is self-sufficient for understanding the concepts it tries to illustrate. It starts on chapter 1 by introducing the most important concepts, the XAML language itself, what can be declared in XAML and how to do it, what are dependency and attached properties as well as markup extensions and events, which should give readers a most required introduction to how WPF works and how to do basic stuff. It moves on to resources on chapter 2, which also makes since, since it’s such an important concept in WPF. Next, chapter 3, come the panels used for laying controls on the screen, all of the out of the box panels are described with typical use cases. Controls come next in chapter 4; the difference between elements and controls is introduced, as well as content controls, headered controls and items controls, and all standard controls are introduced. The book shows how to change the way they look by using templates. The next chapter, 5, talks about top level windows and the WPF application object: how to access startup arguments, how to set the main window, using standard dialogs and there’s even a sample on how to have a irregularly-shaped window. This is one of the most important concepts in WPF: data binding, which is the theme for the following chapter, 6. All common scenarios are introduced, the binding modes, directions, triggers, etc. It talks about the INotifyPropertyChanged interface and how to use it for notifying data binding subscribers of changes in data sources. Data templates and selectors are also covered, as are value converters and data triggers. Examples include master-detail and sorting, grouping and filtering collections and binding trees and grids. Last it covers validation rules and error templates. Chapter 7 talks about the current trend in WPF development, the Model View View-Model (MVVM) framework. This is a well known pattern for connecting things interface to actions, and it is explained competently. A typical implementation is presented which also presents the command pattern used throughout WPF. A complete application using MVVM is presented from start to finish, including typical features such as undo. Style and layout is covered on chapter 8. Why/how to use styles, applying them automatically,  using the many types of triggers to change styles automatically, using Expression Blend behaviors and templates are all covered. Next chapter, 9, is about graphics and animations programming. It explains how to create shapes, transform common UI elements, apply special effects and perform simple animations. The following chapter, 10, is about creating custom controls, either by deriving from UserControl or from an existing control or framework element class, applying custom templates for changing the way the control looks. One useful example is a custom layout panel that arranges its children along a circumference. The final chapter, 11, is about multi-threading programming and how one can integrate it with WPF. Includes how to invoke methods and properties on WPF classes from threads other than the main UI, using background tasks and timers and even using the new C# 5.0 asynchronous operations. It’s an interesting book, like I said, mostly for newcomers. It provides a competent introduction to WPF, with examples that cover the most common scenarios and also give directions to more complex ones. I recommend it to everyone wishing to learn WPF.

• SQL SERVER – Example of Performance Tuning for Advanced Users with DB Optimizer

  - by Pinal Dave

  Performance tuning is such a subject that everyone wants to master it. In beginning everybody is at a novice level and spend lots of time learning how to master the art of performance tuning. However, as we progress further the tuning of the system keeps on getting very difficult. I have understood in my early career there should be no need of ego in the technology field. There are always better solutions and better ideas out there and we should not resist them. Instead of resisting the change and new wave I personally adopt it. Here is a similar example, as I personally progress to the master level of performance tuning, I face that it is getting harder to come up with optimal solutions. In such scenarios I rely on various tools to teach me how I can do things better. Once I learn about tools, I am often able to come up with better solutions when I face the similar situation next time. A few days ago I had received a query where the user wanted to tune it further to get the maximum out of the performance. I have re-written the similar query with the help of AdventureWorks sample database. SELECT * FROM HumanResources.Employee e INNER JOIN HumanResources.EmployeeDepartmentHistory edh ON e.BusinessEntityID = edh.BusinessEntityID INNER JOIN HumanResources.Shift s ON edh.ShiftID = s.ShiftID; User had similar query to above query was used in very critical report and wanted to get best out of the query. When I looked at the query – here were my initial thoughts Use only column in the select statements as much as you want in the application Let us look at the query pattern and data workload and find out the optimal index for it Before I give further solutions I was told by the user that they need all the columns from all the tables and creating index was not allowed in their system. He can only re-write queries or use hints to further tune this query. Now I was in the constraint box – I believe * was not a great idea but if they wanted all the columns, I believe we can’t do much besides using *. Additionally, if I cannot create a further index, I must come up with some creative way to write this query. I personally do not like to use hints in my application but there are cases when hints work out magically and gives optimal solutions. Finally, I decided to use Embarcadero’s DB Optimizer. It is a fantastic tool and very helpful when it is about performance tuning. I have previously explained how it works over here. First open DBOptimizer and open Tuning Job from File >> New >> Tuning Job. Once you open DBOptimizer Tuning Job follow the various steps indicates in the following diagram. Essentially we will take our original script and will paste that into Step 1: New SQL Text and right after that we will enable Step 2 for Generating Various cases, Step 3 for Detailed Analysis and Step 4 for Executing each generated case. Finally we will click on Analysis in Step 5 which will generate the report detailed analysis in the result pan. The detailed pan looks like. It generates various cases of T-SQL based on the original query. It applies various hints and available hints to the query and generate various execution plans of the query and displays them in the resultant. You can clearly notice that original query had a cost of 0.0841 and logical reads about 607 pages. Whereas various options which are just following it has different execution cost as well logical read. There are few cases where we have higher logical read and there are few cases where as we have very low logical read. If we pay attention the very next row to original query have Merge_Join_Query in description and have lowest execution cost value of 0.044 and have lowest Logical Reads of 29. This row contains the query which is the most optimal re-write of the original query. Let us double click over it. Here is the query: SELECT * FROM HumanResources.Employee e INNER JOIN HumanResources.EmployeeDepartmentHistory edh ON e.BusinessEntityID = edh.BusinessEntityID INNER JOIN HumanResources.Shift s ON edh.ShiftID = s.ShiftID OPTION (MERGE JOIN) If you notice above query have additional hint of Merge Join. With the help of this Merge Join query hint this query is now performing much better than before. The entire process takes less than 60 seconds. Please note that it the join hint Merge Join was optimal for this query but it is not necessary that the same hint will be helpful in all the queries. Additionally, if the workload or data pattern changes the query hint of merge join may be no more optimal join. In that case, we will have to redo the entire exercise once again. This is the reason I do not like to use hints in my queries and I discourage all of my users to use the same. However, if you look at this example, this is a great case where hints are optimizing the performance of the query. It is humanly not possible to test out various query hints and index options with the query to figure out which is the most optimal solution. Sometimes, we need to depend on the efficiency tools like DB Optimizer to guide us the way and select the best option from the suggestion provided. Let me know what you think of this article as well your experience with DB Optimizer. Please leave a comment.

• Start/Stop Window Service from ASP.NET page

  - by kaushalparik27

  Last week, I needed to complete one task on which I am going to blog about in this entry. The task is "Create a control panel like webpage to control (Start/Stop) Window Services which are part of my solution installed on computer where the main application is hosted". Here are the important points to accomplish:[1] You need to add System.ServiceProcess reference in your application. This namespace holds ServiceController Class to access the window service.[2] You need to check the status of the window services before you explicitly start or stop it.[3] By default, IIS application runs under ASP.NET account which doesn't have access rights permission to window service. So, Very Important part of the solution is: Impersonation. You need to impersonate the application/part of the code with the User Credentials which is having proper rights and permission to access the window service. If you try to access window service it will generate "access denied" error.The alternatives are: You can either impersonate whole application by adding Identity tag in web.cofig as:        <identity impersonate="true" userName="" password=""/>This tag will be under System.Web section. the "userName" and "password" will be the credentials of the user which is having rights to access the window service. But, this would not be a wise and good solution; because you may not impersonate whole website like this just to have access window service (which is going to be a small part of code).Second alternative is: Only impersonate part of code where you need to access the window service to start or stop it. I opted this one. But, to be fair; I am really unaware of the code part for impersonation. So, I just googled it and injected the code in my solution in a separate class file named as "Impersonate" with required static methods. In Impersonate class; impersonateValidUser() is the method to impersonate a part of code and undoImpersonation() is the method to undo the impersonation. Below is one example:  You need to provide domain name (which is "." if you are working on your home computer), username and password of appropriate user to impersonate.[4] Here, it is very important to note that: You need to have to store the Access Credentials (username and password) which you are going to user for impersonation; to some secured and encrypted format. I have used Machinekey Encryption to store the value encrypted value inside database.[5] So now; The real part is to start or stop a window service. You are almost done; because ServiceController class has simple Start() and Stop() methods to start or stop a window service. A ServiceController class has parametrized constructor that takes name of the service as parameter.Code to Start the window service: Code to Stop the window service: Isn't that too easy! ServiceController made it easy :) I have attached a working example with this post here to start/stop "SQLBrowser" service where you need to provide proper credentials who have permission to access to window service.  hope it would helps./.

• Sun Fire X4800 M2 Delivers World Record TPC-C for x86 Systems

  - by Brian

  Oracle's Sun Fire X4800 M2 server equipped with eight 2.4 GHz Intel Xeon Processor E7-8870 chips obtained a result of 5,055,888 tpmC on the TPC-C benchmark. This result is a world record for x86 servers. Oracle demonstrated this world record database performance running Oracle Database 11g Release 2 Enterprise Edition with Partitioning. The Sun Fire X4800 M2 server delivered a new x86 TPC-C world record of 5,055,888 tpmC with a price performance of $0.89/tpmC using Oracle Database 11g Release 2. This configuration is available 06/26/12. The Sun Fire X4800 M2 server delivers 3.0x times better performance than the next 8-processor result, an IBM System p 570 equipped with POWER6 processors.

It simulates a complete environment where a population of terminal operators executes transactions against a database. The benchmark is centered around the principal activities (transactions) of an order-entry environment. These transactions include entering and delivering orders, recording payments, checking the status of orders, and monitoring the level of stock at the warehouses. Key Points and Best Practices Oracle Database 11g Release 2 Enterprise Edition with Partitioning scales easily to this high level of performance. COMSTAR (Common Multiprotocol SCSI Target) is the software framework that enables an Oracle Solaris host to serve as a SCSI Target platform. COMSTAR uses a modular approach to break the huge task of handling all the different pieces in a SCSI target subsystem into independent functional modules which are glued together by the SCSI Target Mode Framework (STMF). The modules implementing functionality at SCSI level (disk, tape, medium changer etc.) are not required to know about the underlying transport. And the modules implementing the transport protocol (FC, iSCSI, etc.) are not aware of the SCSI-level functionality of the packets they are transporting. The framework hides the details of allocation providing execution context and cleanup of SCSI commands and associated resources and simplifies the task of writing the SCSI or transport modules. Oracle iPlanet Web Server middleware is used for the client tier of the benchmark. Each web server instance supports more than a quarter-million users while satisfying the response time requirement from the TPC-C benchmark.

• SQLAuthority News – Technology and Online Learning – Personal Technology Tip

  - by pinaldave

  This is the fourth post in my series about Personal Technology Tips and Tricks, and I knew exactly what I wanted to write about.  But at first I was conflicted.   Is online learning really a personal tip?  Is it really a trick that no one knows?  However, I have decided to stick with my original idea because online learning is everywhere.  It’s a trick that we can’t – and shouldn’t – overlook.  Here are ten of my ideas about how we should be taking advantage of online learning. 1) Get ahead in the work place.  We all know that a good way to become better at your job, and to become more competitive for promotions and raises.  Many people overlook online learning as a way to get job training, though, thinking it is a path for people still seeking their high school or college diplomas.  But take a look at what companies like Pluralsight offer, and you might be pleasantly surprised. 2) Flexibility.  Some of us remember the heady days of college with nostalgia, others remember it with loathing.  A lot of bad memories come from remembering the strict scheduling and deadlines of college.  But with online learning, the classes fit into your free time – you don’t have to schedule your life around classes.  Even better, there are usually no homework or test deadlines, only one final deadline where all work must be completed.  This allows students to work at their own pace – my next point. 3) Learn at your own pace.  One thing traditional classes suffer from is that they are highly structured.  If you work more quickly than the rest of the class, or especially if you work more slowly, traditional classes do not work for you.  Online courses let you move as quickly or as slowly as you find necessary. 4) Fill gaps in your knowledge.  I’m sure I am not the only one who has thought to myself “I would love to take a course on X, Y, or Z.”  The problem is that it can be very hard to find the perfect class that teaches exactly what you’re interested in, at a time and a price that’s right.  But online courses are far easier to tailor exactly to your tastes. 5) Fits into your schedule.  Even harder to find than a class you’re interested in is one that fits into your schedule.  If you hold down a job – even a part time job – you know it’s next to impossible to find class times that work for you.  Online classes can be taken anytime, anywhere.  On your lunch break, in your car, or in your pajamas at the end of the day. 6) Student centered.  Online learning has to stay competitive.  There are hundreds, even thousands of options for students, and every provider has to find a way to lure in students and provide them with a good education.  The best kind of online classes know that they need to provide great classes, flexible scheduling, and high quality to attract students – and the student benefit from this kind of attention. 7) You can save money.  The average cost for a college diploma in the US is over $20,000.  I don’t know about you, but that is not the kind of money I just have lying around for a rainy day.  Sometimes I think I’d love to go back to school, but not for that price tag.  Online courses are much, much more affordable.  And even better, you can pick and choose what courses you’d like to take, and avoid all the “electives” in college. 8) Get access to the best minds in the business.  One of the perks of being the best in your field is that you are one person who knows the most about something.  If students are lucky, you will choose to share that knowledge with them on a college campus.  For the hundreds of other students who don’t live in your area and don’t attend your school, they are out of luck.  But luckily for them, more and more online courses is attracting the best minds in the business, and if you enroll online, you can take advantage of these minds, too. 9) Save your time.  Getting a four year degree is a great decision, and I encourage everyone to pursue their Bachelor’s – and beyond.  But if you have already tried to go to school, or already have a degree but are thinking of switching fields, four years of your life is a long time to go back and redo things.  Getting your online degree will save you time by allowing you to work at your own pace, set your own schedule, and take only the classes you’re interested in. 10) Variety of degrees and programs.  If you’re not sure what you’re interested in, or if you only need a few classes here and there to finish a program, online classes are perfect for you.  You can pick and choose what you’d like, and sample a wide variety without spending too much money. I hope I’ve outlined for everyone just a few ways that they could benefit from online learning.  If you’re still unconvinced, just check out a few of my other articles that expand more on these topics.

• How to Restore the Real Internet Explorer Desktop Icon in Windows 7

  - by The Geek

  Remember how previous versions of Windows had an Internet Explorer icon on the desktop, and you could right-click it to quickly access the Internet Options screen? It’s completely gone in Windows 7, but a geeky hack can bring it back. Microsoft removed this feature to comply with all those murky legal battles they’ve had, and their alternate suggestion is to create a standard shortcut to iexplore.exe on the Desktop, but it’s not the same thing. We’ve got a registry hack to bring it back. This guest article was written by Ramesh from the WinHelpOnline blog, where he’s got loads of really geeky registry hacks. Bring Back the Internet Explorer Namespace Icon in Windows 7 the Easy Way If you just want the IE icon back, all you need to do is download the RealInternetExplorerIcon.zip file, extract the contents, and then double-click on the w7_ie_icon_restore.reg file. That’s all you have to do. There’s also an undo registry file there if you want to get rid of it. Download the Real Internet Explorer Icon Registry Hack Manual Registry Hack If you prefer doing things the manual way, or just really want to understand how this hack works, you can follow through the manual steps below to learn how it was done, but we’ll have to warn you that it’s a lot of steps. Launch Regedit.exe using the Start Menu search box, and then navigate to the following location: HKEY_CLASSES_ROOT \ CLSID \ {871C5380-42A0-1069-A2EA-08002B30309D} Right-click on the key on the left-hand pane, choose Export, and save it to a .REG file (say, ie-guid.reg) Open up the REG file using Notepad… From the Edit menu, click Replace, and replace every occurrence of the following GUID string {871C5380-42A0-1069-A2EA-08002B30309D} … with a custom GUID string, such as: {871C5380-42A0-1069-A2EA-08002B30301D} Save the REG file and close Notepad, and then double-click on the file to merge the contents to the registry. Either re-open the registry editor, or use the F5 key to reload everything with the new changes (this step is important). Now you can navigate downto the following registry key: HKEY_CLASSES_ROOT \ CLSID \ {871C5380-42A0-1069-A2EA-08002B30301D} \ Shellex \ ContextMenuHandlers \ ieframe Double-click on the (default) key in the right-hand pane and set its data as: {871C5380-42A0-1069-A2EA-08002B30309D} With this done, press F5 on the desktop and you’ll see the Internet Explorer icon that looks like this: The icon appears incomplete without the Properties command in right click menu, so keep reading. Final Registry Hack Adjustments Click on the following key, which should still be viewable in your Registry editor window from the last step. HKEY_CLASSES_ROOT\CLSID\{871C5380-42A0-1069-A2EA-08002B30301D} Double-click LocalizedString in the right-hand pane and type the following data to rename the icon. Internet Explorer Select the following key: HKEY_CLASSES_ROOT\CLSID\{871C5380-42A0-1069-A2EA-08002B30301D}\shell Add a subkey and name it as Properties, then select the Properties key, double-click the (default) value and type the following: P&roperties Create a String value named Position, and type the following data bottom At this point the window should look something like this: Under Properties, create a subkey and name it as Command, and then set its (default) value as follows: control.exe inetcpl.cpl Navigate down to the following key, and then delete the value named LegacyDisable HKEY_CLASSES_ROOT \ CLSID \ {871C5380-42A0-1069-A2EA-08002B30301D} \ shell \ OpenHomePage Now head to the this key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ Desktop \ NameSpace Create a subkey named {871C5380-42A0-1069-A2EA-08002B30301D} (which is the custom GUID that we used earlier in this article.) Press F5 to refresh the Desktop, and here is how the Internet Explorer icon would look like, finally. That’s it! It only took 24 steps, but you made it through to the end—of course, you could just download the registry hack and get the icon back with a double-click.

• World Record Batch Rate on Oracle JD Edwards Consolidated Workload with SPARC T4-2

  - by Brian

  Oracle produced a World Record batch throughput for single system results on Oracle's JD Edwards EnterpriseOne Day-in-the-Life benchmark using Oracle's SPARC T4-2 server running Oracle Solaris Containers and consolidating JD Edwards EnterpriseOne, Oracle WebLogic servers and the Oracle Database 11g Release 2. The workload includes both online and batch workload. The SPARC T4-2 server delivered a result of 8,000 online users while concurrently executing a mix of JD Edwards EnterpriseOne Long and Short batch processes at 95.5 UBEs/min (Universal Batch Engines per minute). In order to obtain this record benchmark result, the JD Edwards EnterpriseOne, Oracle WebLogic and Oracle Database 11g Release 2 servers were executed each in separate Oracle Solaris Containers which enabled optimal system resources distribution and performance together with scalable and manageable virtualization. One SPARC T4-2 server running Oracle Solaris Containers and consolidating JD Edwards EnterpriseOne, Oracle WebLogic servers and the Oracle Database 11g Release 2 utilized only 55% of the available CPU power. The Oracle DB server in a Shared Server configuration allows for optimized CPU resource utilization and significant memory savings on the SPARC T4-2 server without sacrificing performance. This configuration with SPARC T4-2 server has achieved 33% more Users/core, 47% more UBEs/min and 78% more Users/rack unit than the IBM Power 770 server. The SPARC T4-2 server with 2 processors ran the JD Edwards "Day-in-the-Life" benchmark and supported 8,000 concurrent online users while concurrently executing mixed batch workloads at 95.5 UBEs per minute. The IBM Power 770 server with twice as many processors supported only 12,000 concurrent online users while concurrently executing mixed batch workloads at only 65 UBEs per minute. This benchmark demonstrates more than 2x cost savings by consolidating the complete solution in a single SPARC T4-2 server compared to earlier published results of 10,000 users and 67 UBEs per minute on two SPARC T4-2 and SPARC T4-1. The Oracle DB server used mirrored (RAID 1) volumes for the database providing high availability for the data without impacting performance.

Oracle offers 70 JD Edwards EnterpriseOne application modules to support a diverse set of business operations. Oracle's Day in the Life (DIL) kit is a suite of scripts that exercises most common transactions of JD Edwards EnterpriseOne applications, including business processes such as payroll, sales order, purchase order, work order, and manufacturing processes, such as ship confirmation. These are labeled by industry acronyms such as SCM, CRM, HCM, SRM and FMS. The kit's scripts execute transactions typical of a mid-sized manufacturing company. The workload consists of online transactions and the UBE – Universal Business Engine workload of 61 short and 4 long UBEs. LoadRunner runs the DIL workload, collects the user’s transactions response times and reports the key metric of Combined Weighted Average Transaction Response time. The UBE processes workload runs from the JD Enterprise Application server. Oracle's UBE processes come as three flavors: Short UBEs < 1 minute engage in Business Report and Summary Analysis, Mid UBEs > 1 minute create a large report of Account, Balance, and Full Address, Long UBEs > 2 minutes simulate Payroll, Sales Order, night only jobs. The UBE workload generates large numbers of PDF files reports and log files. The UBE Queues are categorized as the QBATCHD, a single threaded queue for large and medium UBEs, and the QPROCESS queue for short UBEs run concurrently. Oracle's UBE process performance metric is Number of Maximum Concurrent UBE processes at transaction rate, UBEs/minute. Key Points and Best Practices Two JD Edwards EnterpriseOne Application Servers, two Oracle WebLogic Servers 11g Release 1 coupled with two Oracle Web Tier HTTP server instances and one Oracle Database 11g Release 2 database on a single SPARC T4-2 server were hosted in separate Oracle Solaris Containers bound to four processor sets to demonstrate consolidation of multiple applications, web servers and the database with best resource utilizations. Interrupt fencing was configured on all Oracle Solaris Containers to channel the interrupts to processors other than the processor sets used for the JD Edwards Application server, Oracle WebLogic servers and the database server. A Oracle WebLogic vertical cluster was configured on each WebServer Container with twelve managed instances each to load balance users' requests and to provide the infrastructure that enables scaling to high number of users with ease of deployment and high availability. The database log writer was run in the real time RT class and bound to a processor set. The database redo logs were configured on the raw disk partitions. The Oracle Solaris Container running the Enterprise Application server completed 61 Short UBEs, 4 Long UBEs concurrently as the mixed size batch workload. The mixed size UBEs ran concurrently from the Enterprise Application server with the 8,000 online users driven by the LoadRunner.

  The 11gR2 11.2.0.2 Database was certified with E-Business Suite (EBS) 11i and EBS 12 almost one year ago today.  I’m pleased to announce that 11.2.0.3, the second patchset for the 11gR2 Database is now certified. Be sure to review the interoperability notes for R11i and R12 for the most up-to-date requirements for deployment. This certification announcement is important as you plan upgrades to the technology stack for your environment. For additional upgrade direction, please refer to the recently published EBS upgrade recommendations article. Database support implications may also be reviewed in the database patching and support article.
