• DIVS over flash movies in Internet Explorer

  - by drew

  The age old question... why the hell doesn't a div positioned over a flash object stay on top with z-index. I have found the answer in the past, but it's been so long, I can't seem to get it. My flash movie is in a div floating left: <div id="flash"> <object width="614" height="289"> <param name="movie" value="images/75.swf"> <param name="wmode" value="transparent"> <embed src="images/75.swf" width="614" height="289" wmode"transparent"> </embed> </object> </div> My css for the div that needs to be on top is: .menu ul li:hover ul li a:hover { background:#5a3f2d; color:#FFF; z-index: 9999; I cannot get it to show above the flash movie in ie6 or ie8. I know this is old school but I'm frustrated! Does my nav div need to have an absolute position? Is that why it doesn't work? Example is here. Hover over the first link on the right: "CUSTOMER SERVICE" Thanks all :)

• Am I Writing Assembly Or NASM?

  - by cam

  I'm fed up with this. I've been trying to just get a grip on assembly for awhile, but I feel like I'm coding towards my compiler rather than a language. I've been using this tutorial, and so far it's giving me hell. I'm using NASM, which may be the problem, but I figured it was the most popular one. I'm simply trying to learn the most general form of assembly, so I decided to learn x86. I keep running into stupid errors, like not being able to increment a variable. Here's the latest one: not being able to use div. mov bx, 0; mov cx, 0; jmp start; start: inc cx; mov ax, cx; div 3; <-- invalid combination of opcode and operand cmp ah,0; jz totalvalue; mov ax, cx; div 5; <-- invalid combination of opcode and operand cmp ah, 0; jz totalvalue; cmp cx, 1000; jz end; totalvalue: add bx,cx; jmp start; jmp end; end: mov ah,4ch; mov al,00; int 21h; Should I change compilers? It seems like division should be standard. Do I need to read two tutorials (one on NASM, and one on x86?). Any specific help on this problem?

• beautifulsoup: find the n-th element's sibling

  - by deostroll

  I have a complex html DOM tree of the following nature: <table> ... <tr> <td> ... </td> <td> <table> <tr> <td> <!-- inner most table --> <table> ... </table> <h2>This is hell!</h2> <td> </tr> </table> </td> </tr> </table> I have some logic to find out the inner most table. But after having found it, I need to get the next sibling element (h2). Is there anyway you can do this?

• Downloading jQuery UI: Ok, so what part of this mess do I copy to the server?

  - by Martha

  From the "should be simple, but..." files: Trying to get started with jQuery UI. Went to the site, used their custom builder thingy to assemble the parts I need, made myself a custom theme using the Theme Roller, downloaded the zip file thus produced, unzipped it on my local drive. Ok, so I have 37 folders, 311 files, and a total of 2.4 MB. Ain't no way in hell all this is going on the server. What parts do I need to put there? 'css' 'custom-theme': jquery-ui-1.8.custom.css, 'images' subfolder with 12 .png images 'development-bundle' 'demos': demos.css, index.html, plus 18 subfolders, but I'm guessing "not needed" 'docs': 17 .html files, but again, I'm guessing "not needed" 'external': 4 .js files, one .css 'themes': 'base' and 'custom-theme' subfolders, each with 8 or 9 .css files and an 'images' subfolder with about a dozen images 'ui': 25 .js files, an 'i18n' subfolder with 53 .js files, and a 'minified' subfolder with 24 .js files 'js': jquery-1.4.2.min.js and jquery-ui-1.8.custom.min.js Also, the file structure. Our server is set up something like this: root admin (administrative tools) css forms (the gist of the site lives here) images include (asp code snippets that are used by multiple pages) js (just a few things right now, like an ancient wheezing spelling checker) As far as I can tell, the jQuery css files assume that (1) each theme is in its own folder, and (2) each folder has its own images subfolder. How can I convince it otherwise? i.e. put the necessary .js files in the 'js' folder, the .css files in the 'css' folder, and the images in the 'images' folder?

• Obtaining Current Fiscal Year from Hierarchy with MDX

  - by Robert Iver

  I'm building a report in Reporting Services 2005 based on a SSAS 2005 cube. The basic idea of the report is that they want to see sales for this fiscal year to date vs. last year sales year to date. It sounds simple, but being that this is my first "real" report based on SSAS, I'm having a hell of a time. First, how would one calculate the current fiscal year, quarter, or month. I have a Fiscal Date Hierarchy with all that information in it, but I can't figure out how to say: "Based on today's date, find the current fiscal year, quarter, and month." My second, but slightly smaller problem, is getting last years sales vs. this years sales. I have seen MANY examples on how to do this, but they all assume that you select the date manually. Since this is a report and will run pretty much on it's own, I need a way to insert the "current" fiscal year, quarter, and month into the PERIODSTODATE or PARALLELPERIOD functions to get what I want. So, I'm begging for your help on this one. I have to have this report done by tomorrow monring and I'm beginning to freak out a bit. Thanks in advance.

• django: cannot import settings, cannot login to admin, cannot change admin password

  - by xpanta

  Hi, It seems that I am completely lost here. Yesterday I noticed that I cannot login to the admin panel (don't use it much, so it's been some weeks since last login). I thought that I might have changed the admin password and now I can't remember it (though I doubt it). I tried django-admin.py changepassword (using django 1.2.1) but it said that 'changepassword' is unknown command (I have all the necessary imports in my settings.py. Admin interface used to work ok). Then I gave a django-admin.py validate. Then the hell begun. django-admin.py validate gave me this error: Error: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined. I then gave a set DJANGO_SETTINGS_MODULE=myproject.settings and then again a django-admin.py validate This is what I get now: Error: Could not import settings 'myproject.settings' (Is it on sys.path? Does it have syntax errors?): No module named myproject.settings and now I am lost. I tried django console and sys.path.append('c:\workspace') or sys.append('c:\workspace\myproject') but still get the same errors. I use windows 7 and my project dir is c:\workspace. I don't use a PYTHONPATH variable (although I tried setting it temporarily to C:\workspace but I still get the same error). I don't use Apache, just the django development server. What am I doing wrong? My web page works fine. I think that the fact that I can't login as admin is related to the previous import error, no? PS: I also tried this: http://coderseye.com/2007/howto-reset-the-admin-password-in-django.html but still I couldn't change admin password for some reason. Although I could create another admin user (with which I couldn't login).

• How should I unit test a code-generator?

  - by jkp

  This is a difficult and open-ended question I know, but I thought I'd throw it to the floor and see if anyone had any interesting suggestions. I have developed a code-generator that takes our python interface to our C++ code (generated via SWIG) and generates code needed to expose this as WebServices. When I developed this code I did it using TDD, but I've found my tests to be brittle as hell. Because each test essentially wanted to verify that for a given bit of input code (which happens to be a C++ header) I'd get a given bit of outputted code I wrote a small engine that reads test definitions from XML input files and generates test cases from these expectations. The problem is I dread going in to modify the code at all. That and the fact that the unit tests themselves are a: complex, and b: brittle. So I'm trying to think of alternative approaches to this problem, and it strikes me I'm perhaps tackling it the wrong way. Maybe I need to focus more on the outcome, IE: does the code I generate actually run and do what I want it to, rather than, does the code look the way I want it to. Has anyone got any experiences of something similar to this they would care to share?

• Django: Serving Media Behind Custom URL

  - by TheLizardKing

  So I of course know that serving static files through Django will send you straight to hell but I am confused on how to use a custom url to mask the true location of the file using Django. http://stackoverflow.com/questions/2681338/django-serving-a-download-in-a-generic-view but the answer I accepted seems to be the "wrong" way of doing things. urls.py: url(r'^song/(?P<song_id>\d+)/download/$', song_download, name='song_download'), views.py: def song_download(request, song_id): song = Song.objects.get(id=song_id) fsock = open(os.path.join(song.path, song.filename)) response = HttpResponse(fsock, mimetype='audio/mpeg') response['Content-Disposition'] = "attachment; filename=%s - %s.mp3" % (song.artist, song.title) return response This solution works perfectly but not perfectly enough it turns out. How can I avoid having a direct link to the mp3 while still serving through nginx/apache? EDIT 1 - ADDITIONAL INFO Currently I can get my files by using an address such as: http://www.example.com/music/song/1692/download/ But the above mentioned method is the devil's work. How can I accomplished what I get above while still making nginx/apache serve the media? Is this something that should be done at the webserver level? Some crazy mod_rewrite? http://static.example.com/music/Aphex%20Twin%20-%20Richard%20D.%20James%20(V0)/10%20Logon-Rock%20Witch.mp3

• Looking for a good dev environment for OSGi bundles

  - by Riduidel

  Hi, I'm currently investigating in the field of dev environment for OSGi bundles. My goal is to find a way to develop, test and debug with ease the bundles I'll be coding. Besides, I have some "cultural" requirements. I want to be able to use java continuous integration servers (typically, Hudson) As a consequence of that first requirement, I want to have a repeatable, one-click build process. My typical tool for that is maven. And finally, being long-term Eclipse user, and having the m2eclipse at hand to merge my eclipse env with my maven one, I obviously want to be able to test and debug with that IDE. So far, here are the infos I know I can use (and have already tested) maven-bundle-plugin, maven-ipojo-plugin which both offer clean packaging facilities I have tested maven pax (and eclipse pax) and am not really satisfied with both : maven pax generates a very heavy project, where adding dependencies is very error-prone (the maven pax:import-bundle command line, with all its arguments, is a hell per se) I have taken a look at Karaf, which seems to have some nice direct maven provisionning, but I don't know how to integrate it with my Eclipse, besides using the traditionnal JPDA bridge. However, it seems to be more production-oriented than dev-oriented, and as such may require heavy configuration to fit my need (although the reading of its user manual doesn't revedal that). Have you got any ideas ? Some maven/eclipse plugins ?

• Have I taken a wrong path in programming by being excessively worried about code elegance and style?

  - by Ygam

  I am in a major stump right now. I am a BSIT graduate, but I only started actual programming less than a year ago. I observed that I have the following attitude in programming: I tend to be more of a purist, scorning unelegant approaches to solving problems using code I tend to look at anything in a large scale, planning everything before I start coding, either in simple flowcharts or complex UML charts I have a really strong impulse on refactoring my code, even if I miss deadlines or prolong development times I am obsessed with good directory structures, file naming conventions, class, method, and variable naming conventions I tend to always want to study something new, even, as I said, at the cost of missing deadlines I tend to see software development as something to engineer, to architect; that is, seeing how things relate to each other and how blocks of code can interact (I am a huge fan of loose coupling) i.e the OOP thinking I tend to combine OOP and procedural coding whenever I see fit I want my code to execute fast (thus the elegant approaches and refactoring) This bothers me because I see my colleagues doing much better the other way around (aside from the fact that they started programming since our first year in college). By the other way around I mean, they fire up coding, gets the job done much faster because they don't have to really look at how clean their codes are or how elegant their algorithms are, they don't bother with OOP however big their projects are, they mostly use web APIs, piece them together and voila! Working code! CLients are happy, they get paid fast, at the expense of a really unmaintainable or hard-to-read code that lacks structure and conventions, or slow executions of certain actions (which the common reasoning against would be that internet connections are much faster these days, hardware is more powerful). The excuse I often receive is clients don't care about how you write the code, but they do care about how long you deliver it. If it works then all is good. Now, did my "purist" approach to programming may have been the wrong way to start programming? Should I just dump these purist concepts and just code the hell up because I have seen it: clients don't really care how beautifully coded it is?

• Any teams out there using TypeMock? Is it worth the hefty price tag?

  - by dferraro

  Hi, I hope this question is not 'controversial' - I'm just basically asking - has anyone here purchased TypeMock and been happy (or unhappy) with the results? We are a small dev shop of only 12 developers including the 2 dev managers. We've been using NMock so far but there are limitations. I have done research and started playing with TypeMock and I love it. It's super clean syntax and lets you basically mock everything, which is great for legacy code. The problem is - how do I justify to my boss spending 800-1200$ per license for an API which has 4-5 competitors that are completly free? 800-1200$ is how much Infragistrics or Telerik cost per license - and there sure as hell isn't 4-5 open source comparable UI frameworks... Which is why I find it a bit overpriced, albeit an awesome library... Any opinions / experiences are greatly appreciated. EDIT: after finding MOQ I thought I fell in love - until I found out that it's not fully supported in VB.NET because VB lacks lambda sub routines =(. Is anyone using MOQ for VB.NET? The problem is we are a mixed shop - we use C# for our CRM development and VB for everything else. Any guidence is greatly appreciated again

• Does a VCL OrgChart component with decent features exists? Is there a viable alternative?

  - by user193655

  I am using DevExpress OrgChart component that is still maintained but not developed since 2003 (fortunately bugs are fixed, but nothing more). Honestly this component, even if it starts to look too old still suffices my requirements except for 2 things: 1) it doesn't support at all the staff feature, for understanding what I mean see this image (where the items in staff are Administration, Communication, IT, Special Projects). 2) it arranges the items without optimizing the space, for example if there are 3 items at top level, and only the second item has 2 childs, the top items items are drawn more distantly, because of the 2 childs, there is no an option for "shirinking" the diagram. Of course the component misses tons of the features one would expect from an OrgChart tool, but in my case Those 2, and expecially (1) are important, the rest is lack of eye-candy. I look for VCL components, but if (as I fear, since I never found it) such component doesn't exist) I can see the following alternatives: i) using Hydra with .net winforms components ii) using ActiveX components. Between the 2 I would prefer ActiveX because of the .NET deployment hell (what I like about Delphi is that you ship the exe to the customer witn Win2k and it works). Anyway I never used an activeX control and I don't know which are the deployment issues, but I fear I will lose the opportunity of replacing an exe and upgrading the software. iii) hire a delphi component develoeper that can customize the DevEx component by adding feature (1) and maybe (2). I am stuck.

• Strongly Typed Controls in .NET

  - by Tigraine

  I am working on a Windows Forms app for quite some time now, and I really find myself doing more typecasts in the GUI code than I ever did in my underlying business code. What I mean becomes apparent if you watch the ComboBox control that accepts some vague "object" as it's item. Then you go off and may display some DisplayMember and a ValueMember and so on. If I want to retrieve that value later I need to typecast my object back to what it was. Like with strings getting the value takes string value = (string)combobox1.SelectedItem; Since there are generics in the Framework for quite some time now, I still wonder why in the Hell not one control from the standard toolbox is generic. I also find myself using the .Tag property on ListViewItems all the time to keep the displayed domain object. But everytime I need to access that object I then need another typecast. Why cant I just create a ComboBox or ListView with items of type ListViewItem Am I missing something here or is this just another example of not perfectly well thought through controls?

• Any info about book "Unix Internals: The New Frontiers" by Uresh Vahalia 2nd edition (Jan 2010)

  - by claws

  This summer I'm getting into UNIX (mostly *BSD) development. I've graduate level knowledge about operating systems. I can also understand the code & read from here and there but the thing is I want to make most of my time. Reading books are best for this. From my search I found that these two books The Design and Implementation of the 4.4 BSD Operating System "Unix Internals: The New Frontiers" by Uresh Vahalia are like established books on UNIX OS internals. But the thing is these books are pretty much outdated. yay!! Lucky me. "Unix Internals: The New Frontiers" by Uresh Vahalia 2 edition (Jan 2010) is released. I've been search for information on this book. Sadly, Amazon says "Out of Print--Limited Availability" & I couldn't find any info regarding this book. This is the information I'm looking for: Table of Contents Whats new in this edition? Where the hell can I buy soft-copy of this book? I really cannot afford buying a hardcopy. How can I contact the author? I've lot of hopes & expectations on this book. I've been waiting for its release for a long time. I've sent random mails to & & requesting to have a proper website for this book. I even contacted publisher for any further information but no replies from any one. If you have any other books that you think will help me. I again repeat, I want to get max possible out of these 2.5 months summer.

• .Net assembly references being lost as soon as project is compiled

  - by Truegilly

  I have a windows service project, one of many C# projects in a solution file. I add a reference to my "Data_objects" class library for my windows service. this is added to the references no problem. all the classes become available and I can begin to code. As soon a I compile the windows service it says "The type or namespace name 'Data_Objects' could not be found (are you missing a using directive or an assembly reference?)" yet in the solution explorer the reference is fine, no yellow exclamation mark. I have to remove and add it again for it to pick it up, but then as soon as I compile it loses it. This reference works fine in my two other web application projects. what the hell is going on !! Truegilly Update there are no naming conflicts the only bit of code I have is a using statement - eg using Data_Objects.DataContext; also this only happens with a windows service project, i just created a new web app project and it works fine.

• Web page database query optimization

  - by morpheous

  I am putting together a web page which is quite 'expensive' in terms of database hits. I don't want to start optimizing at this stage - though with me trying to hit a deadline, I may end up not optimizing at all. Currently the page requires 18 (that's right eighteen) hits to the db. I am already using joins, and some of the queries are UNIONed to minimize the trips to the db. My local dev machine can handle this (page is not slow) however, I feel if I release this into the wild, the number of queries will quickly overwhelm my database (MySQL). I could always use memcache or something similar, but I would much rather continue with my other dev work that needs to be completed before the deadline - at least retrieving the page works - its simply a matter of optimization now (if required). My question therefore is - is 18 db queries for a single page retrieval completely outrageous - (i.e. I should put everything on hold and optimize the hell of the retrieval logic), or shall I continue as normal, meet the deadline and release on schedule and see what happens? [Edit] Just to clarify, I have already done the 'obvious' things like using (single and composite) indexes for fields used in the queries. What I haven't yet done is to run a query analyzer to see if my indexes etc are optimal.

• Horizontal and vertical center text in html

  - by Christophe Herreman

  I have a div with a background image that needs to be centered horizontally and vertically. On top of that image, I also want to display a 1-line text, also centered horizontally and vertically. I managed to get the image centered, but the text is not centered vertically. I thought vertical-align:middle would do the trick. Here's the code I have: <div style="background: url('background.png') no-repeat center; width:100%; height:100%; text-align:center;"> <div style="color:#ffffff; text-align: center; vertical-align:middle;" > Some text here. </div> </div> Any ideas? Workaround: I actually got this to work by using a table. (I'll probably be cursed to hell by the HTML community.) Is there any significant reason not to use this btw? I'm still interested in the solution using divs though. <table width="100%" height="100%"> <tr> <td align="center" style="background: url('background.png') no-repeat center; color:#ffffff;">Some text here.</td> </tr> </table>

• Database and logic layer for ASP.NET MVC application

  - by Ismail

  I'm going to start a new project which is going to be small initially but may grow to big over the years. I'm strongly convinced that I'm going to use ASP.NET MVC with jQuery for UI. I want to go for MySQL as database for some reasons but worried on few things. I've a good years of experience working on SQL Server databases and on one project I've had a bad experience creating and managing stored procedures on MySQL database. I'm totally new to Linq but I see that it is easier to use once you are familiar with it. First thing is that accessing data should be easy. So I thought I should use MySQL to Linq but somewhere I read that it is not directly supported but MySQL .NET connector adds support for EntityFramework. I don't know what are the pros and cons of it. I would love if I can implement repository pattern as it allows to apply filter in logic layer rather than in data access layer. Will it be possible if I use Entity Framework? I'm not clear on how I should go about all this or I should just forget every thing and directly use SQL to Linq on SQL Server. I'm also concerned about the performance. Someone told me that if we use Entity framework it fetches lot of data and then filter it. Is that right? So questions basically are - Is MySQL to Linq possible? If yes where can I get more details on it? Pros and cons of using EntityFramework with MySQL? Will it be easy to access data using EntityFramework with MySQL? Will I be able to implement repository patter which allows applying filter in logic layer rather than data access layer (when I use EntityFramework with MySQL) Does it fetches hell lot of data from database and then apply filter on it? If it sounds too many questions from my side in that case, if you can just let me know what you will do (with a considerable reason) in this situation as an experienced person in this area, that should answer my question.

• I can't find the cause of an "unchecked or unsafe operations" warning in Java.

  - by Peter

  Hello, as per the title I am struggling to find the cause of an "unchecked or unsafe operations" warning in some code. If I have the following code, it compiles without any warnings: public void test() { Set<String> mySet = new HashSet<String>(); Set<String> myNewSet = mySet; //do stuff } Now, if I change where mySet comes from, specifically as the result of a method call, I get the "unchecked yadda yadda" warning: public void test() { Set<String> myNewSet = this.getSet(); //do stuff } public Set getSet() { Set<String> set = new HashSet<String>(); return set; } I have tried and tried to work out what the problem is and I am completely stumped. The issue is present whether I use Sets or Lists. Why would the Set returned by the getSet method be any different to the Set in the first example? Any help would be greatly appreciated as while the warning isn't the end of the world, it is bugging the hell out of me! :( Regards

• Find out which row caused the error

  - by Felipe Fiali

  I have a big fat query that's written dynamically to integrate some data. Basically what it does is query some tables, join some other ones, treat some data, and then insert it into a final table. The problem is that there's too much data, and we can't really trust the sources, because there could be some errored or inconsistent data. For example, I've spent almost an hour looking for an error while developing using a customer's database because somewhere in the middle of my big fat query there was an error converting some varchar to datetime. It turned out to be that they had some sales dating '2009-02-29', an out-of-range date. And yes, I know. Why was that stored as varchar? Well, the source database has 3 columns for dates, 'Month', 'Day' and 'Year'. I have no idea why it's like that, but still, it is. But how the hell would I treat that, if the source is not trustable? I can't HANDLE exceptions, I really need that it comes up to another level with the original message, but I wanted to provide some more info, so that the user could at least try to solve it before calling us. So I thought about displaying to the user the row number, or some ID that would at least give him some idea of what record he'd have to correct. That's also a hard job because there will be times when the integration will run up to 80000 records. And in an 80000 records integration, a single dummy error message: 'The conversion of a varchar data type to a datetime data type resulted in an out-of-range datetime value' means nothing at all. So any idea would be appreciated. Oh I'm using SQL Server 2005 with Service Pack 3.

• How to use Data aware controls "correctly"?

  - by lyborko

  Hi, I would like to ask experienced users, if you prefer to use data aware controls to add, insert, delete and edit data in DB or you favor to do it manualy. I developed some DB applications, in which for the sake of "user friendly policy" I run into complicated web of table events (afterinsert, afteredit, after... and beforeedit, beforeinsert, before...). After that it was a quite nasty work to debug the application. Aware of this risk (later by another application) I tried to avoid this problem, so I paid increased attention to write code well, readable and comprehensive. It seemed everything all right from the beginning, but as I needed to handle some preprocessing stuff before sending and loading data etc, I run into the same problems again, "slowly and inevitably". Sometime I could not use dataaware controls anyway, and what seemed to be a "cool" feature of DAControl at the beginning it turned to an obstacle on the end. I "had to" write special routine for non-dataaware controls, in order to behave as dataaware. Then I asked myself, why on earth should I use dataaware controls? Is it better to found application architecture on non-dataaware controls? It requires more time to write bug-proof code, of course, but does it worth of it? I do not know... I happened to me several times, like jinxed : paradise on the beginning hell on the end... I do not know, if I use wrong method to write DB program, if there is some standard common practice how to proceed. Or if it is common problem to everybody? Thanx for advices and your experiences

• stackoverflow tags and related tags

  - by parminder

  Hi Experts, I am working on a website where a user can add tags to their posted books. It is similar to stackover flow, but I am keeping my tags in differnt table. so here are the tables/class in linq to entities. Books { bookId, Title } Tags { Id Tag } BooksTags { Id BookId TagId } Here are few sample records. Books BookId Title 113421 A 113422 B Tags Id Tag 1 ASP 2 C# 3 CSS 4 VB 5 VB.NET 6 PHP 7 java 8 pascal BooksTags Id BookId TagId 1 113421 1 2 113421 2 3 113421 3 4 113421 4 5 113422 1 6 113422 4 7 113422 8 Question 1 : I need to write something in linq to entities queries which gives me data according to the tags say if I want bookIds where tagid =1 it should return bookid 113421 and 113422 as it exists in both the books, but If I ask data for tags 1 and 2 it should return only book 113421 as that is the only book where both the tags are present. Question 2 : I need tags and their count too to show in related tags, so in first case my related tags class should have following result. RelatedTags Tag Count 2 1 3 1 4 2 8 1 in the second case when two tags are requested the result should be like RelatedTags Tag Count 3 1 4 1 I have get the first thing working by converting a sql query in linqer, but that seems like a hell. so want to know if there is any better idea. I have used dyanmic where clause to include two tags. So if someone can help. It will be much appreciated. Thanks Parminder

• What programming language is this?

  - by Richard M.

  I recently stumbled over a very odd source listing on a rather old programming-related site (lost it somewhere in my browser history as I didn't care about it at first). I think that this is part of a simple (console-based?) snake game. I searched and searched but didn't find a language that looked somwhat like this. This seems like a mix of Python, Ruby and C++. What the hell? What programming-language is the below source listing written in? Maybe you can figure it out? my Snake.hasProps { length parts xDir yDir } & hasMethods { init: length = 0 parts[0].x,y = 5 move: parts[ 0 ].x,y.!add xDir | yDir # Move the head map parts(i,v): parts[ i ] = parts[ i + 1 ] checkBiteSelf checkFeed checkBiteSelf: part } my SnakePart.hasProps { x y } fork SnakePart to !Feed my Game.hasProps { frameTime = 30 } & hasMethods { init: mainloop mainloop: sys.util.sleep frameTime Snake.move Field.getInput -> Snake.xDir | Snake.yDir Field.reDraw with Snake & Feed & Game # For FPS } main.isMethod { game.init }

• How to create a "Shell IDList Array" to support drag-and-drop of virtual files from C# to Windows Ex

  - by JustABill

  I started trying to implement drag-and-drop of virtual files (from a C# 4/WPF app) with this codeplex tutorial. After spending some time trying to figure out a DV_E_FORMATETC error, I figured out I need to support the "Shell IDList Array" data format. But there seems to be next to zero documentation on what this format actually does. After some searching, I found this page on advanced data transfer which said that a Shell IDList Array was a pointer to a CIDA structure. This CIDA structure then contains the number of PIDLs, and a list of offsets to them. So what the hell is a PIDL? After some more searching, this page sort of implies it's a pointer to an ITEMIDLIST, which itself contains a single member that is a list of SHITEMIDs. My next idea was to try dragging a file from another application with virtual files. I just got a MemoryStream back for this format. At least I know what class to provide for the thing, but that doesn't help at all for explaining what to put in it. So now that that's explained, I still have no idea how to create one of these things so that it's valid. There's two real questions here: What is a valid "abID" member for a SHITEMID? These virtual files only exist with my program; will the thing they are dragged to pass the "abID" back later when it executes GetData? Do they have to be system-unique? Why are there two levels of lists; a list of PIDLs and each PIDL has a list of SHITEMIDs? I'm assuming one of them is one for each file, but what's the other one for? Multiple IDs for the same file? Any help or even links that explain what I should be doing would be greatly appreciated.
