• JS DOM: Get elements by text content.

  - by hristo

  Hello! I am looking for a way to perform fulltext search on the DOM tree with JS. In two words, I would like to retrieve the list of text nodes which contain a given string. I've tried mootools' Element.getElements ( ':contains[string]' ) but I can't get it to work with strings containing whitespace. I'm thinking about simply indexing all text nodes and checking against each node for the string being searched for, but, in my project, there's no way of telling when the DOM updates in order to maintain such an index up-to-date. Any better ideas? Thanks

• How do you reference another element in a xaml list

  - by Ball

  I'm using xaml as a datastore because It's quick and we haven't yet defined a file format. But I can only seem to create xaml that is a pure tree, even if it is acyclic. I know how to create a list of items in xaml, but How do I share objects in two lists? Below is an example of what I'm trying to say. <CreaturFile> <CreatureFile.Monsters> <Monster Name="Kobold" x:Name="Mepo"/> <Monster Name="Goblin"/> </CreatureFile.Monsters> <CreatureFile.Encounters> <Encounter> <Reference ElementName="Mepo"/> </Encounter> </CreatureFile.Encounters> </CreatureFile>

• Pattern for iPhone background loading during init?

  - by Rob S.

  Hi everyone, I'm currently kicking off a background thread to do some REST queries in my app delegate's didFinishLaunchingWithOptions. This thread creates some objects and populates the model as the rest of the app continues to load (because I don't block, and didFinishLaunchingWithOptions returns YES). I also put up a loading UIViewController 'on top' of the main view that I tear down after the background initialization is complete. My problem is that I need to notify the first view (call it the Home view) that the model is ready, and that it should populate itself. The trick is that the background download could have finished before Home.viewDidAppear is called, or any of the other Home.initX methods. I'm having difficulty synchronizing all of this and I've thought about it long enough that it feels like I'm barking up the wrong tree. Are there any patterns here for this sort of thing? I'm sure other apps start by performing lengthy operations with loading screens :) Thanks!

• How to rate a connect four game situation in java

  - by MrPink

  Hey, I am trying to write a simple AI for a "Get four" game. The basic game principles are done, so I can throw in coins of different color, and they stack on each other and fill a 2D Array and so on and so forth. until now this is what the method looks like: public int insert(int x, int color) //0 = empty, 1=player1 2=player2" X is the horizontal coordinate, as the y coordinate is determined by how many stones are in the array already, I think the idea is obvious. Now the problem is I have to rate specific game situations, so find how many new pairs, triplets and possible 4 in a row I can get in a specific situation to then give each situation a specific value. With these values I can setup a "Game tree" to then decide which move would be best next (later on implementing Alpha-Beta-Pruning). My current problem is that I can't think of an efficient way to implement a rating of the current game situation in a java method. Any ideas would be greatly appreciated! greetings from Germany Mr. Pink

• Icons in Silverlight: Images vs. Vectors

  - by Shnitzel

  I like using the vector drawing feature of Expression Blend to create icons. That way I can change colors easily on my icons without having to resort to an image editor. But my question is... Say I have a treeview control that has an icon next to each tree element and say I have hundreds of elements. Do you think using images is faster - performance wise than using vector icons? B/c I'd rather use vectors but I'm wondering about performance concerns.

• How to call an xslt transform into an xsl stylesheet

  - by Mycol

  I have written an xslt that reads some xml file names and does some operations on them. I use a for-each to work them one-by-one. I have each path inside a parameter $path. But now I would like to output the result of applying an external stylesheet to those files. I would write something like <div> <something like xsl-transform($extern-xslt,$path)> </div> to have the result tree of the transformation inside the main html output. It is possible?

• silverlight adding single prism command delegate to a list of items in xaml

  - by bobwah

  I'm building a menu using Prism (using a trtelerik tree view with hierarchy data templates but hopefully the details don't matter) and I'm trying to set up a Click.Command on each menu items bindings that will all call the same delegate command which is defined in the view model. The menu is built up out of items which I don't really want to put any references to the command in. How do I bind the command to each of these items in xaml? I've looked around and it looks like in WPF I could use a relative source binding and find ancestors but there doesn't seem to be a way of doing this in silverlight. Can I setup the delegate as a static resource somehow? I don't think I can create a static resource to the view model as this uses Unity to resolve paramters to it's constructor.

• Problem with accessing in DOM with jQuery

  - by Tristan

  Hello, I changed the tree of my JSON-P output, and i cannot access to my object DOM anymore : Here's my output : jsonp1271634374310( {"Inter-Medias": {"name":"Inter-Medias","idGSP":"14","average":"80","services":"8.86"} }); And here's my jQuery script : success: function(data, textStatus, XMLHttpRequest){ widget = data.name; widget += data.average ; .... I know one level is missing, but if I try to do : data.Inter-Medias.name or data.name.name it's still not working. Any idea please ? I will have case where i'll have multiple Ojbect, so i want to display all of them, how to do that ? for (i=0;i < data.length;i++) Does it look right ? Bonus question : i understand function(data, textStatus, XMLHttpRequest) that in case of success this function is triggered, the data is what the script recieved from his request, but i have no idea what textStatus or XMLHttpRequest are here too and why ?! Thank you.

• Predicates and Lists

  - by George

  Hello guys, I have a generic list. Some elements of this list belong to a parent element. I retrieved all these elements from a database and i want to recursively build a tree with them. So, here's what i'm thinking: Here is my predicate: public static bool FindChildren(Int32 parentId,CategoryMapping catMapping) { if (catMapping.parentId == parentId) { return true; } else { return false; } } root = list[0]; root.childrenElements = root.FindAll(FindChildren(root.id,???) I can't figure out how this would work. How can i do this kind of predicate?

• Infinite recursion trying to check all elements of a TreeCtrl

  - by mavnn

  I have a TreeCtrl in which more than one Item can be assigned the same object as PyData. When the object is updated, I want to update all of the items in the tree which have that object as their PyData. I thought the following code would solve the problem quite neatly, but for some reason the logical test (current != self.GetFirstVisibleItem()) always returns true leading to infinite recursion. Can anyone explain why? def RefreshNodes(self, obj, current=None): print "Entered refresh" current = current or self.GetFirstVisibleItem() if current.IsOk(): print self.GetPyData(current).name if self.GetPyData(current) == obj: self.RefreshNode(current) current = self.GetNextVisible(current) if current != self.GetFirstVisibleItem(): self.RefreshNodes(obj, current) Edit: the above is obviously part of a class based on wx.TreeCtrl

• Save the contents of manipulated div to a variable and pass to php file

  - by Danielle Zarcaro

  I have tried to use AJAX, but nothing I come up with seems to work correctly. I am creating a menu editor. I echo part of a file using php and manipulate it using javascript/jquery/ajax (I found the code for that here: http://www.prodevtips.com/2010/03/07/jquery-drag-and-drop-to-sort-tree/). Now I need to get the edited contents of the div (which has an unordered list in it) I am echoing and save it to a variable so I can write it to the file again. I couldn't get that resource's code to work so I'm trying to come up with another solution. If there is a code I can put into the $("#save").click(function(){ }); part of the javascript file, that would work, but the .post doesn't seem to want to work for me. If there is a way to initiate a php preg_match in an onclick, that would be the easiest. Any help would be greatly appreciated.

• Listing and deleting Git commits that are under no branch (dangling?)

  - by Samer Abukhait

  I've got a git repository with plenty of commits that are under no particular branch, I can git show them but when I try to list branches that contain them, it reports back nothing: I thought this is the dangling commits/tree issue (as a result of -D branch), so I pruned the repo, but I still see the case after that: $ git fetch origin $ git fsck --unreachable $ git fsck No output, nothing dangling (right?) $ git show 793db7f272ba4bbdd1e32f14410a52a412667042 commit 793db7f272ba4bbdd1e32f14410a52a412667042 Author: .. But $ git branch --contains 793db7f272ba4bbdd1e32f14410a52a412667042 Gives no output What exactly is the state of that commit? How can I list all commits with similar state, How can I delete commits like those?

• decentralized development using git and git-svn

  - by CantGetANick

  We have 2-3 small teams of 2-3 people. We all use git for local and svn for central repository and git-svn got sync. This is works all the time except when we want to share our code between the team it self. So we have tried out git pull, this creates lots of conflicts and it does not detect that we are on the same tree. It fetches all the changes (same as clone then pull) Of course i dont want to clone full repo. every time I want to share. Please suggest a better flow. We can't get rid of central svn. We can't clone every time.

• How to create diagrams for papers.

  - by Simon

  I want to create some diagrams for some papers. Diagrams will contain some text, e.g. some console output. I need images for using also in html files. There is TikZ so can create images like this: http://www.texample.net/tikz/examples/boxes-with-text-and-math/ http://www.texample.net/tikz/examples/rule-based-diagram/ http://www.texample.net/tikz/examples/scenario-tree/ but as a result I get some ps/pdf files, not images. What's more I want to generate the pictures from text files as I want to track changes in some VCS, any binary files are not suitable for that.

• Playing around with my Java project in Eclipse... what the crap did I just do?

  - by Daddy Warbox

  I don't even remember how, but somehow I managed to make all of my project's source files hidden in Eclipse's Package and Project Explorer panels. Go figure. 'Show Filtered Children (alt+click)' temporarily reveals the files, and only in Package Explorer can I double-click to reopen them from this view. They go back into hiding after I select another item, though. Plus, now I'm getting other annoyances, such as all of the folded non-hidden items altogether expanding when I click on an item, and the entire folder tree of my project now being shown in these panels (including my .svn subversion folders... which shouldn't be any of Eclipse's business, presently). Long story short, my Package/Project Explorers' just blew up on me, and I want to know how to fix this. Thanks in advance. P.S. What's a good guide I can use to learn my way around this silly contraption, anyway?

• Why do I get the error "X is not a member of Y" even though X is a friend of Y?

  I am trying to write a binary tree. Why does the following code report error C2039, "'<<' : is not a member of 'btree<T'" even though the << operator has been declared as a friend function in the btree class? #include<iostream> using namespace std; template<class T> class btree { public: friend ostream& operator<<(ostream &,T); }; template<class T> ostream& btree<T>::operator<<(ostream &o,T s) { o<<s.i<<'\t'<<s.n; return o; }

• C# Event routing in code behind

  - by Nate

  I'm building a WPF MVVM-ish application. I want to be able to display an event log containing items in a collection that exists in my viewmodel. I want any of the objects in the model to be able to add data to the event log. Therefore every object needs to be able to pass data back to one central collection for databinding in the view. I could implement an event in every one of my data classes and manually pass the events up the object heirarchy but this seems super clumsy. On the visual tree a Routed Event would take care of this, is there some equivelent in the model scope? Any other ideas?

• Dynamically adding Views in Silverlight & MVVM

  - by dvox

  Hi all, I am starting to re-write my whole silverlight business application in the MVVM pattern; My first stop-point is this: I have a page (View1) with corresponding ViewModel1 (with a property 'IEnumerable AllData'); Now, within this View, I want to have i.e. a tree-view control, in which one node will be populated with another View2; My question is: 1. How to do it? - I can't loop through the AllData property since it is asynchronously loaded... - thus I don't know the number of View2s' to insert - I don't know how to do it from ViewModel1 :( Will I need ViewModel2 with property 'MyDataEntity CurrentData'? or I can bind to AllData property from ViewModel1 Can you help me out? Thanks

• Business web application platform structure

  - by VoodooRider

  Hi, I would like to develop a web application in java/spring/hibernate serving as a business platform that I could connect plugins to (i.e. CRM plugin, ware plugin, sales plugin). Those plugins could be dependent of other plugins in a tree manner. The parent project would be packaged as war having all the basic configuration and looks (spring configs, css, scripts), ready to go user and group management, security settings, etc. All together I would like it to behave and look a bit like Joomla, but built using different tools for different purposes. And I have a few questions concerning that project: Do you know of any open source projects offering such a platform ready to go? If not is maven applicable for managing those plugins? What is the best way to package and deploy those plugins? And the last but not least, basically is this the right way to go or is a dead end and it would be better to create a separate web app for those business needs?

• Why Does TFS Allow Orphaned Content and How Do I Get Rid of It?

  - by Chad

  My TfsVersionControl database has grown to 40+ GB in size. We recently did a TFS Destroy on a folder tree that should have cleared up at least 10 GB but instead it seemed to have no effect. When I look at the tables in TfsVersionControl, I am first shocked to see that there are no foreign keys at all in the database. Running a few queries, I see that there is some orphaning going on: tbl_Content has 13.9 GB of records that don't have a related tbl_File record tbl_File and tbl_Content have 2.4 GB that don't have a related tbl_Namespace record The cleanup job seems to be running nightly (prc_DeleteUnusedContent) and running it against the database manually doesn't remove any orphans. I see in the log for the cleanup job that it failed on 3/16, which is the morning after I destroyed the large amount of data. The error was due to a full transaction log. Could that error be the reason I'm left with all this orphaned data that can't be deleted? How can I permanently destroy this unneeded content?

• How do I "merge" two separate git repositories of the same website without losing commit data?

  - by PHLAK

  I have two separate git repositories for the same version of a single website. domain.com-1.0 domain.com-2.0 Version 2.0 was completely redone from the ground up. There is no bridge between the two repositories. I would now like to merge the two into a single repository, but maintain the separation. I have already tagged domain.com-1.0 in it's repo and now want to clean the working tree and move domain-2.0 and all it's commit history into 1.0's repo. Is this possible or is there a better way of accomplishing this? Note: domain.com-1.0 will not be developed on anymore and is "being retired".
