• Non-Embedded Content for your Popup Controls Target Container

  Yesterday I posted about client side predicates for Popup controls. Thanks for all the Tweets and Emails. The Popup control is very powerful and Popups are now an expected construct in many web user interfaces. I received a number of questions about using content in Popups that is not embedded in the containing page. Probably the easiest is to use in iFrame inside the Panel container for the Popup. In code it looks like this. Code Snippet <h1>Modal iFrame</h1> <asp:Button...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• libstdc++-6.dll not found. [migrated]

  - by Molmasepic

  I have been working on a project(a game to be specific) and I feel that I should start over with different libraries. So when doing this I reinstalled Code::Blocks and setup my new libraries and includes. But as of now Im having a problem starting u[ my new project to test if all of the includes work. This problem is: libstdc++-6.dll was not found. At first i wondered if I could just find this file online, but its nowhere to be found(or at least the many places I have searched...) Soon after, I tried loading up my old project, and the same problem happened again(wierd... ._.) I was thinking its maybe my compiler, so I used my older compiler and it did the same thing! At this moment I held the problem off for tomorrow(which is today) So my question is: If anyone else had this problem, how would you solve it? Im using Code::Blocks with MinGW as the compiler on Windows Vista 32 bit.

• Use Extension Methods to find first and last day of the month

  - by Tim Hibbard

  A lot of reports work on data from last month.  It is a nice touch to have these dates pre-populated for your users.  Using extension methods, the code can look cleaner too. Extension Methods: public static class DateHelper { public static DateTime FirstOfTheMonth(this DateTime dt) { return new DateTime(dt.Year, dt.Month, 1); }   public static DateTime LastOfTheMonth(this DateTime dt) { return dt.FirstOfTheMonth().AddMonths(1).AddDays(-1); } } Consuming Code: void Prepopulate() { startDateBox.CurrentlySelectedDate = DateTime.Now.AddMonths(-1).FirstOfTheMonth(); endDateBox.CurrentlySelectedDate = DateTime.Now.AddMonths(-1).LastOfTheMonth(); }

• I've totally missed the point of distributed vcs [closed]

  - by NimChimpsky

  I thought the major benefit of it was that each developers code gets stored within each others repository. My impression was that each developer has their working directory, their own repository, and then a copy of the other developers repository. Removing the need for central server, as you have as many backups as you have developers/repositories Turns out this is nto the case, and your code is only backed up (somewhere other than locally) when you push, the same as a commit in subversions. I am bit disappointed ... hopefully I will be pleasantly surprised when it handles merges better and there are less conflicts ?

• Best book/source to learn the unix commands

  - by Kraken

  So I was intern at this company wherein they'd use just putty. Now I've never worked with unix commands, apart from the basic , compile code , run C code. But now I would love to know all the things about the unix. Starting off with the commands, from the most basic of all to the decent level. Also, moving forward, how the different folders/files are arranged in a unix (ubuntu is installed on my system) system. I have picked up a couple of books, but they dont seem to help. Can someone suggest a comprehensive book that'll fulfill my needs. Because, working with a GUI on ubuntu does not really give me the real feel of things. Hence I'd want to move on to the terminal instead. Thanks.

• Using "Google Guava" in coding interviews

  - by kbgn27

  I attended a in-person interview recently and performed well. But surprisingly I got rejected. When I asked the HR for reason, he contacted the technical interviewer and told me that I was syntactically wrong while coding. I used Google Guava for coding. So my code looked like this: List<String> items = Lists.newArrayList() instead of List<String> items =new ArrayList<String>(); I know that the code will compile and work as expected.Is it ok to use third party libraries like Google Guava in interviews?

• Vocabulary: Should I call this apply or map?

  - by Carlos Vergara

  So, I'm tasked with organizing the code and building a library with all the common code among our products. One thing that seems to happen all the time and I wanted to abstract is posted below in pseudocode, and I don't know how to call it (different products have different domain specific implementations and names for it) list function idk_what_to_name_it ( list list_of_callbacks, value common_parameter ): list list_of_results = new list for_each(callback in list_of_callbacks) list_of_results.push(callback(common_parameter)) end for_each return list_of_results end function Would you call this specific construct a list ListOfCallbacks.Map( value value_to_map) method or would it better be value Value.apply(list list_of_callbacks) I'm really curious about this kind of thing. Is there a standard guide for this stuff?

• Finding the try for an except or finally [migrated]

  - by ?s?

  I'm dealing with some code that has fantastically long methods (10k lines!) and some odd use of try-finally and try-except blocks. Some of the latter are long by themselves, and don't always have the try at the start of the method. Obviously I'm trying to refactor the code, but in the meantime just being able to fix a couple of common pathologies would be much easier if I could jump to the start of a block and see what is happening there. When it's 20+ pages away finding it even with the CNPack rainbows is just tedious. I'm using D2010 and have GExperts (with DelForExp), CNPack and DDevExtensions installed, but I can't find anything that lets me jump from the try to the finally or back. Am I missing something? Is there another add-in that I can use that will get me this?

• Is this a pattern? Should it be?

  - by Arkadiy

  The following is more of a statement than a question - it describes something that may be a pattern. The question is: is this a known pattern? Or, if it's not, should it be? I've had a situation where I had to iterate over two dissimilar multi-layer data structures and copy information from one to the other. Depending on particular use case, I had around eight different kinds of layers, combined in about eight different combinations: A-B-C B-C A-C D-E A-D-E and so on After a few unsuccessful attempts to factor out the repetition of per-layer iteration code, I realized that the key difficulty in this refactoring was the fact that the bottom level needed access to data gathered at higher levels. To explicitly accommodate this requirement, I introduced IterationContext class with a number of get() and set() methods for accumulating the necessary information. In the end, I had the following class structure: class Iterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const = 0; }; class RecursingIterator : public Iterator { RecursingIterator(const Iterator &below); }; class IterateOverA : public RecursingIterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // Iterate over members in dataStructure1 // locate corresponding item in dataStructure2 (passed via context) // and set it in the context // invoke the sub-iterator }; class IterateOverB : public RecursingIterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // iterate over members dataStructure2 (form context) // set dataStructure2's item in the context // locate corresponding item in dataStructure2 (passed via context) // invoke the sub-iterator }; void main() { class FinalCopy : public Iterator { virtual void iterateOver(const Structure &dataStructure1, IterationContext &ctx) const { // copy data from structure 1 to structure 2 in the context, // using some data from higher levels as needed } } IterationContext ctx(dateStructure2); IterateOverA(IterateOverB(FinalCopy())).iterate(dataStructure1, ctx); } It so happens that dataStructure1 is a uniform data structure, similar to XML DOM in that respect, while dataStructure2 is a legacy data structure made of various structs and arrays. This allows me to pass dataStructure1 outside of the context for convenience. In general, either side of the iteration or both sides may be passed via context, as convenient. The key situation points are: complicated code that needs to be invoked in "layers", with multiple combinations of layer types possible at the bottom layer, the information from top layers needs to be visible. The key implementation points are: use of context class to access the data from all levels of iteration complicated iteration code encapsulated in implementation of pure virtual function two interfaces - one aware of underlying iterator, one not aware of it. use of const & to simplify the usage syntax.

• Collision rectangle response

  - by dotty

  I'm having difficulties getting a moveable rectangle to collide with more than one rectangle. I'm using SFML and it has a handy function called Intersect() which takes 2 rectangles and returns the intersections. I have a vector full of rectangles which I want my moveable rectangle to collide with. I'm looping through this using the following code (p is the moveble rectangle). IsCollidingWith returns a bool but also uses SFML's Interesect to work out the intersections. while(unsigned i = 0; i!= testRects.size(); i++){ if(p.IsCollidingWith(testRects[i]){ p.Collide(testRects[i]); } } and the actual Collide() code void gameObj::collide( gameObj collidingObject ){ printf("%f %f\n", this->colliderResult.width, this->colliderResult.height); if (this->colliderResult.width < this->colliderResult.height) { // collided on X if (this->getCollider().left < collidingObject.getCollider().left ) { this->move( -this->colliderResult.width , 0); }else { this->move( this->colliderResult.width, 0 ); } } if(this->colliderResult.width > this->colliderResult.height){ if (this->getCollider().top < collidingObject.getCollider().top ) { this->move( 0, -this->colliderResult.height); }else { this->move( 0, this->colliderResult.height ); } } } and the IsCollidingWith() code is bool gameObj::isCollidingWith( gameObj testObject ){ if (this->getCollider().intersects( testObject.getCollider(), this->colliderResult )) { return true; }else { return false; } } This works fine when there's only 1 Rect in the scene. However, when there's move than one Rect it causes issue when working out 2 collisions at once. Any idea how to deal with this correctly? I have uploaded a video to youtube to show my problem. The console on the far-right shows the width and height of the intersections. You can see on the console that it's trying to calculate 2 collisions at once, I think this is where the problem is being caused. The youtube video is at http://www.youtube.com/watch?v=fA2gflOMcAk also , this image also seems to illustrate the problem nicely. Can someone please help, I've been stuck on this all weekend!

• Adobe Air apps on the Mac App Store?

  - by coneybeare

  Before you chastise me for asking this, I have an Adobe Air app that has a lot of investment in it, and if there is a way to utilize the existing code-base in any way, it is worth considering. I have heard news reports in passing about Adobe creating some kind of tool to allow flash or air apps to be ported to native objective-c code, but the information found in google is mostly commentary on the one-time Apple blockade. My question(s) is/are this: Is it even possible, at any level, to use an existing Air app to create a Mac Store app? If possible, what are the resources I can use to accomplish this?

• Cocos2d iOS A* Star Path finding help

  Hello I need help implementing this class https://github.com/sqlboy/tiled-games/tree/master/src into my iOS game. Im using the suggested code of: AStarPathFinder pathFinder = [[AStarPathFinder alloc] initWithTileMap:tileMap collideLayer:@"collide"]; // Optionally, you can set the name of the collide property key and the value it expects. [pathFinder setCollideKey:@"collidable"] // defaults to COLLIDE [pathFinder setCollideValue:@"True"] // defaults to 1 // highlight a path (src and dst are tile coorindates) [pathFinder highlightPathFrom:srcTile to:dstTile]; // move a sprite [pathFinder moveSprite:player from:srcTile to:dstTile atSpeed:0.1f]; I get the following error: Instance method '-initWithTileMap:collideLayer:' not found (return defaults to 'id') This is the official post for the class: http://www.cocos2d-iphone.org/forums/topic/just-pushed-a-cctmxtiledmap-a-pathfinding-class-to-github/ The only other code I added was: #import "AStarPathFinder.h" I think I am perhaps missing something! I am grateful for any help!

• Writing long line support for text editor

  - by Mathematician82

  I know that some some text editors have problems to show long lines https://bugzilla.gnome.org/show_bug.cgi?id=172099 . What is the best way to fix the bug or are they equally well? Modify the GTK+ source code and add a support for long lines. Modify the text editor source code such that it does not use GTK+ if it meets a long line. Split the long lines into part (maybe by cut on the Bash ) I'm just a junior programmer so I don't know what people does when they meet a bug that is on the library they use.

• Control HelpButton, HelpRequested, HelpButtonClicked - Instant help for windows Dialog Form components

  Instant help for windows dialog components is a great feature and very much known since windows 98. but I saw many many people are not aware it and query on Google to get help, but “help button” for dialogs helps you or your customers to get the help instantly. Every dialog window has help icon if that dialog was coded to enable it. it really helps to know the functionality of the components quickly. For example I was trying to pint a document from acrobat reader and opened printer properties to print the content front and back of the paper. If you observe there is a help button before close button. To get help on options of “Print on Both Sides” you would need to click on help button first and then click on the area on which you want to see the help. above picture shows help text for the options of “Print on Both Sides”. If you would like to get the help using keyboard you can use F1 key. Help button can be displayed only if minimize button and maximize button both are not shown unless you want go with custom buttons. below is the way if you want to get Help button for windows forms.   In this sample demo I want to have a checkbox and need to show help when I click on F1 on check box. So I created a form which country check box and help label as show in adjacent picture. Below is the code for your code bind file. using System; using System.Windows.Forms; namespace WindowsFormsApplication1 {     public partial classForm1: Form    {         publicForm1()         {             InitializeComponent();         }         private void Form1_Load(objectsender, EventArgs e)         {             this.Text = "Help Button Demo Form";             lblHelp.Text = "Press F1 on any component to get Instant Help";             this.HelpButton = true;             this.MaximizeBox = false;             this.MinimizeBox = false;             chkCountry.Tag = "Check or Uncheck Coutry Check Box";             chkCountry.HelpRequested += newHelpEventHandler(chkCountry_HelpRequested);             chkCountry.MouseLeave += newEventHandler(chkCountry_MouseLeave);         }         void chkCountry_HelpRequested(objectsender, HelpEventArgs hlpevent)         {             ControlrequestingControl = (Control)sender;             lblHelp.Text = (string)requestingControl.Tag;             hlpevent.Handled = true;         }         void chkCountry_MouseLeave(objectsender, EventArgs e)         {             lblHelp.Text = "Press F1 on any component to get Instant Help";         }     } } In above code  “HelpRequested” is an event will be fired when you click on F1 on Country checkbox. I stored the help information in the checkbox property called “Tag”. You might also maintain a property file to keep help text for each component differently. If you click on F1 when focus is on main form instead on individual component then generally separate help window opens. This can be done using the event “Form.HelpRequested” to open help windows as in below code. this.HelpRequested += newHelpEventHandler(Form1_HelpRequested); voidForm1_HelpRequested(objectsender, HelpEventArgs hlpevent) {     frmHelp.Show(); } span.fullpost {display:none;}

• Getting collision detection in Pygames

  - by user36010

  I am writing a game in Pygame, I want to get collision detection. The aim is when a object hits another, the target object disappears. I want to avoid having classes and just have my code class less for now, in one script. This makes it difficult to get collision detection because the Rect method in Pygame is called on by an object(class). The logic I want to achieve is: object hits a target object target object disappears. is there an easy way to achieve this?(with minimal code possible)

• How to get familiar with "what happens underneath of Java"?

  - by FidEliO

  I did not study CS nor IT. I just became a developer, now working with Java. Actually, since I now work with a big company writing high-scalable web applications, I think I need to be better with details. I have no understanding of what happens underneath of Java. Java Performance, Server-Side Java might be the buzz words?!! I am very poor with those more of low-level details but I do not know where to look honestly. I started looking for some keywords in Amazon, ended up reading books like "pragmatic programmer", "clean code", "code complete" which IMO they are not what I am looking for. Could you please give me some learning resources (books, articles, blog posts, online trainings) for this matter? I also read this post as well: Approaching Java/JVM internals But I think I need a pre-step before jumping into the OpenJDK, right?!

I wanted to rethink on this and need your expert advice and suggestions. As i am working currently in a hot skill(sharepoint 2013) technology, is it a good thought to go ahead and do MBA and change my career, or should i start liking what i do??

• Is this a pattern? Proxy/delegation of interface to existing concrete implementation

  - by Ian Newson

  I occasionally write code like this when I want to replace small parts of an existing implementation: public interface IFoo { void Bar(); } public class Foo : IFoo { public void Bar() { } } public class ProxyFoo : IFoo { private IFoo _Implementation; public ProxyFoo(IFoo implementation) { this._Implementation = implementation; } #region IFoo Members public void Bar() { this._Implementation.Bar(); } #endregion } This is a much smaller example than the real life cases in which I've used this pattern, but if implementing an existing interface or abstract class would require lots of code, most of which is already written, but I need to change a small part of the behaviour, then I will use this pattern. Is this a pattern or an anti pattern? If so, does it have a name and are there any well known pros and cons to this approach? Is there a better way to achieve the same result? Rewriting the interfaces and/or the concrete implementation is not normally an option as it will be provided by a third party library.
