• Handling Data Hierarchies in code

  - by Miau

  Hi there So, say I have a string to parse with a given format that maps to a tree like data structure. The string is kinda similar to a folder path, and the structure is similar to a file structure, except its got some rules so for something@cat1@otherSomething you would get /something/cat1/otherSomething for something@cat2@otherSomething you would get /something/cat2/otherSomething other examples /OtherThing/cat1/otherSomething/Blah /OtherThing/cat4/otherSomething Where something, cat1, otherSomethign, etc are some sort of instances of ICategory There are certain rules that control what subcategories are valid and which subcategories are not acceptable, at the moment I m considering a heavy Object hierachy, but I know this is not a flexible solution, I d prefer the categories to be a bit more general but again, since there are rules about what can go next I m not sure how to do this. An example of a rule can be: OtherThing can only have subcategories cat1 and cat4 ( anything else is invalid) An option would be to use some sort of convention based aproach to instantiate a particular class given a subsection of the string(like cat4) but it seems a bit too complex, I m all ears Thanks

• Select elements based on class and element type

  - by Beau Martínez

  How can I select all elements within an HTML document with a specific class and specific element type? I'm trying to select all anchors with the class title loggedin from an HTML document (and then open them within the browser). These are within parragraphs with the class title. They are leafs in the following DOM tree: + body + div class='content' + div id='siteTable' class='sitetable linklisting' + div class='thing id-t3_xxxx xxx xxx link' + div class='entry unvoted' + p class='title' + a class='title loggedin ' Where x indicates variable content. (I'm looking to do this in raw JavaScript, ie, not in jQuery.)

• Generate markdown from source code doc-comments

  - by erikkallen

  Is there any easy way to generate markdown from source code comments? I'm looking for something similar to Sandcastle, but with Markdown (or something like it) as output. The full story is that I use DokuWiki to generate documentation. It has many nice properties, including that all its data is stored in text files. So my idea is that I should somehow be able to get my API docs into the same place as the rest of my documentation. So far my best bet seems to be to write a custom documenter for NDoc3, but perhaps someone has already done something similar which would save me the trouble. I realize I might need to tweak it a little due to slight syntax differences.

• CSS [custom?] attributes

  - by Michael

  radio[pane] { list-style-image: url("jar:resource:///chrome/classic.jar! /skin/classic/browser/preferences/Options.png"); } radio[pane="prefpane-appearance"] { -moz-image-region: rect(0px, 32px, 32px, 0px); } radio[pane="prefpane-appearance"]:hover, radio[pane="prefpane-appearance"][selected="true"] { -moz-image-region: rect(32px, 32px, 64px, 0px); } Can anyone explain a syntax of this css, particularly what is pane.. I couldn't find such attribute for radio element in context of XUL. So I guess it's some custom attribute? If it is, then how it is evolving through the lines, first declaration, then several assignments? It has also selected, which means can have multiple custom attributes? How can those attributes be used later?

• Databinding in windows forms on an object graph with possible null properties?

  - by Fredrik

  If I have an object graph like this: class Company { public Address MainAddress {...} } class Address { public string City { ... } } Company c = new Company(); c.MainAddress = new Address(); c.MainAddress.City = "Stockholm"; and databind to a control using: textBox1.DataBinding.Add( "Text", c, "MainAddress.City" ); Everything is fine, but If I bind to: Company c2 = new Company(); c2 using the same syntax it crashes since the MainAddress property is null. I wonder if there is a custom Binding class that can set up listeners for all the possible paths here and bind to the actual object dynamically when/if I sometime later in the application set the MainAddress property.

• Git history cleanup doesn't seem to have an effect

  - by eaigner

  Hi, i ran the following 2 commands to clean up .pbxuser and .mode1v3 files from my git repository, but afterwards when i e.g. fire up gitx i can still see them in the history. git filter-branch --tree-filter "git rm -rf --cached --ignore-unmatch *.pbxuser" HEAD rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune What did i misunderstand here? The commands seem to do the job but why is gitx still viewing the diffs in its history? Regards, Erik

• How can I load a sql "dump" file into sql alchemy

  - by JudoWill

  I have a large sql dump file ... with multiple CREATE TABLE and INSERT INTO statements. Is there any way to load these all into a SQLAlchemy sqlite database at once. I plan to use the introspected ORM from sqlsoup after I've created the tables. However, when I use the engine.execute() method it complains: sqlite3.Warning: You can only execute one statement at a time. Is there a way to work around this issue. Perhaps splitting the file with a regexp or some kind of parser, but I don't know enough SQL to get all of the cases for the regexp. Any help would be greatly appreciated. Will EDIT: Since this seems important ... The dump file was created with a MySQL database and so it has quite a few commands/syntax that sqlite3 does not understand correctly.

• functions inside or outside jquery document ready

  - by Hans

  Up until now I just put all my jQuery goodness inside the $(document).ready() function, including simple functions used in certain user interactions. But functions that don´t require the DOM document to be loaded or are only called afterwards anyway, can be placed outside the $(document).ready() as well. Consider for example a very simple validation function such as: function hexvalidate(color) { // Validates 3-digit or 6-digit hex color codes var reg = /^(#)?([0-9a-fA-F]{3})([0-9a-fA-F]{3})?$/; return reg.test(color); } The function is only called from within the $(document).ready() function though. What is best practice (syntax, speed); placing such a function inside or outside the jquery document ready function?

• Where are the really high quality and complex Swing components?

  - by jouhni

  Looking at Swing, I have the feeling that it comes with many useful and reasonable atomic components in its core. And when I look at the Web there are hundrets of quickly plugged together components (among them many date/time pickers, pimped lists and tables), which have in common that I could easily write them on my own, if I needed them. When I build big software and come to the point where I need a domain-specific component which is really big, I mostly come to the point where I have to write it on my own, which, due to the point that they are not just plugged together lists and tables, isn't done qickly. So, the question is, why are there no Swing component galleries which contain more than just customized date/time pickers or lists with added tree support. Where are the components which really raise the level of abstraction, or are in best case domain-specific?

• OOWrite is to LaTeX as OODraw is to?

  - by grimborg

  I'm looking for a tool to nicely generate single-page PDFs. My needs are: Able to put a PDF/EPS/... as a background Absolute positioning Able to define tables, lists Able to rotate blocks Reasonably easy syntax (will be used to automatically generate many similar looking documents) Easily usable from Python Free or very cheap In essence I'm looking for the tool X that is to OODraw/CorelDraw/... as LaTeX is to OOWrite/MS Word. I've looked at webkit2pdf and a headless OODraw, but both seem a bit of an overkill. XML-FO has some limitations such as not being able to predict how many pages your document spans. Reportlab is pricey. Any ideas? Thanks!

• What's the VB.NET equivalent of this C# code for wiring up and declaring an event?

  - by Ben McCormack

  I'm working on a tutorial to build a media player in Silverlight and am trying to wire up an EventHandler to the timer.Tick event of a DispatchTimer object so that the time of the video is synced with a Slider object. The sample code is in C# and I can't for the life of me figure out the proper syntax in VB.NET with RaiseEvent and/or Handles to wire up the event. Below is the relevant C# code. I'll include comments on where I'm getting stuck. private DispatchTimer timer; public Page() { //... timer = new DispatchTimer(); timer.Interval = TimeSpan.FromMilliseconds(50); timer.Tick += new EventHandler(timer_Tick); // <== I get stuck here b/c // I can't do "timer.Tick += ..." in VB.NET } void timer_Tick(object sender, EventArgs e) { if (VideoElement.NaturalDuration.TimeSpan.TotalSeconds > 0) { sliderScrubber.Value = VideoElement.Position.TotalSeconds / VideoElement.NaturalDuration.TimeSpan.TotalSeconds; } }

• update table with information from IDirectory

  - by sue

  I have a table with 4 columns, LoginID, LastName, FirstName, Email. The data for LoginID was populated from an other table. I have to write a small routine to update this table, by sending in the LoginID and with help of IDirectory routines, get the Lastname, firstname and email. This is what i'm attempting to do, but getting confused with the right syntax. using (TSADRequestEntities context = UnityHelper.Resolve()) { var fpvalues = context.FOCALPOINTs.ToList(); foreach (var item in fpvalues) { IEnumerable<UserInfo> query = UnityHelper.Resolve<IUserDirectory>().Search(item.LoginID); //Here, FocalPoint is the table that has the loginID and the other fields //I need to update. the query shld now hv info on lastname etc..how do I //retrieve that value and update the table? } }

• Mercurial - How to stop tracking modified file but keep the first version in repository.

  - by teerapap

  I create the hg repository with my source tree. I want to keep the first version of some files such as Makefile in the repository and then hg don't see it modified even through I modified it. Original problem is that ./configure usually modifies the Makefile but I don't want the build files to committed in the repository. So I want to keep only first version of configure and Makefile in the repository so that everybody who clone my repository can run ./configure by themself and not bother the repository I tried hg remove or hg forget but those are stop tracking and also delete the files in the next revision of reporitory. .hgignore doesn't do the things too. I think of hg revert everytimes I run ./configure or make but it's not efficient way. Are there any better ways?

• A Question About the Expressive Power of Higher-Order Logical Reasoning Formalisms.

  - by Bubba88

  Hi! I do not really know if this is scientifically proven, but I've read in a book (It was a relatively modern AI book by Peter Norvig) that secon-order logical programming could be more expressive than existing first-order languages. The question is: Is it statistically/symbolically proven that higher-order predicate logics exceed first-order predicates in their expressive power? Or they just bring the modularity/convenience/maintainability to your knowledge bases? Additionally: If there is some kind of firm direction in which I could go seeking more expressive power than I have (I mean exactly the descriptive potential of the symbols I write in given semantics/syntax) - then I would be glad to hear just almost everything :) Thank you.

• Repeatedly querying xml using python

  - by Jack

  I have some xml documents I need to run queries on. I've created some python scripts (using ElementTree) to do this, since I'm vaguely familiar with using it. The way it works is I run the scripts several times with different arguments, depending on what I want to find out. These files can be relatively large (10MB+) and so it takes rather a long time to parse them. On my system, just running: tree = ElementTree.parse(document) takes around 30 seconds, with a subsequent findall query only adding around a second to that. Seeing as the way I'm doing this requires me to repeatedly parse the file, I was wondering if there was some sort of caching mechanism I can use so that the ElementTree.parse computation can be reduced on subsequent queries. I realise the smart thing to do here may be to try and batch as many queries as possible together in the python script, but I was hoping there might be another way. Thanks.

• Lamda expression will not compile

  - by John Soer

  I am very confused I have this lamba expression tvPatientPrecriptionsEntities.Sort((p1, p2) => p1.MedicationStartDate.Value.CompareTo(p2.MedicationStartDate.Value)); Visual studio will not compile it and complains about syntax. I converted the lamba expression to an anonymous delegate as so tvPatientPrecriptionsEntities.Sort( delegate(PatientPrecriptionsEntity p1, PatientPrecriptionsEntity p2) { return p1.MedicationStartDate.Value.CompareTo(p2.MedicationStartDate.Value); } ); and it works fine. The project is uses the .net 3.5 framework and I have a reference to system.linq.

• AJAX with Ruby on Rails?

  - by Zachary

  This is probably a really dumb question with a simple answer but... I am working on a project where I need to use AJAX to send/receive information. I am using Ruby on Rails (which I am pretty new to), but rather than using the helper methods or the built in functionality in the 'defaults' Javascript file, I need to do this manually in my own Javascript. I believe that ultimately I will want to send a request with a JSON object, then have the controller return another JSON object containing the requested information. The problem is that I cannot seem to find the syntax for sending something to a specific controller method, with parameters, directly from Javascript - everything I Google ends up being tutorials for using the Rails AJAX helper methods.

• storing an integral value in a pointer variable while declaration

  - by benjamin button

  int main() { int *d=0; printf("%d\n",*d); return 0; } this works fine. >cc legal.c > ./a.out 0 if i change the statement int *d=0; to int *d=1; i see the error. cc: "legal.c", line 6: error 1522: Cannot initialize a pointer with an integer constant other than zero. so its obvious that it will allow only zero.i want to know what happens inside the memory when we do this int *d=0 which is making it valid syntax. I am just asking this out of curiosity!

• What is the correct way to reference RDFa namespaces in HTML5?

  - by Eivind Eidheim Elseth

  I'm setting up a HTML5 webpage and want to include RDFa. I try checking the syntax with the w3 validator, and check the extracted RDF using the w3 RDFa distiller. When I declare namespaces using xmlns:<ns>="<uri>" the validator complains that the attribute is not allowed there, and the specs say that xmlns is deprecated, but if I try the other suggested prefix="<ns> <uri>" the distiller doesn't discover the RDFa embedded on my page. Which way should I stick to?

• Did Delphi ever get a for each loop?

  - by Ryan

  Hello, I've read that Delphi was supposed to get a for each loop in Delphi 9. Did this functionality ever make it into the language? My Delphi 2009 IDE doesn't seem to recognize the for each syntax. Here's my code: procedure ProcessDirectory(p_Directory, p_Output : string); var files : TStringList; filePath : string; begin files := GetSubfiles(p_Directory); try for (filePath in files.Strings) do begin // do something end; finally files.Free; end; end;

• MSSQL 2005: Rename DB Server Instance Name?

  - by Code Sherpa

  Hi, Can somebody tell me how to rename the DB server instance name and a DB name in MSSQL 2005? Right Now I Have SERVER/OLDNAME -- oldnameDB I want to change the server instance and also change the db name. I have tried: EXEC sp_renamedb 'oldName', 'newName' and that has changed the dbname as it appers in the tree directory. But, when I do "select @@servername" it is the old name. Also, the MDF and LDF files are still the old name. How do change instance and db names as a clean sweep across the server? Thanks.

• SmartGWT Server File Browser

  - by jluzwick

  Hi All: I have been looking for a SmartGWT example that would show me how to build a File Browser widget that takes the files from the local server's root directory. The user would be shown the files through the browser which they could then select to perform some processing operations. So far I have thought of using SmartGWT's Tree-Data Binding-Load from Local Data Widget and then grabbing a list of the directories using: new File("\").listFiles(); My Question is: Is there a better way to do this? Has someone already thought of this and has an example of their code that I can see? PS: I'm fairly new to GWT and Web Services but fairly competent with Java. If you believe there is a better way to do this (while still doing this through the web and not using Applets, please tell me). Thanks

• Regex: How to match a unix datestamp?

  - by Jono

  I'd like to be able to match this entire line (to highlight this sort of thing in vim): Fri Mar 18 14:10:23 ICT 2011. I'm trying to do it by finding a line that contains ICT 20 (first two digits of the year of the year), like this: syntax match myDate /^*ICT 20*$/, but I can't get it working. I'm very new to regex. Basically what I want to say: find a line that contains "ICT 20" and can have anything on either side of it, and match that whole line. Is there an easy way to do this?
