• How do I store in subversion my customizations to a public open source project?

  - by Clyde

  Hi, I'm working on customizing a couple of open source projects in ways that are very much personalized -- i.e., not appropriate to send the patches back to the maintainers for the public. One of them is stored in CVS, one in SVN. I use SVN for my own work. The CVS project is fine. I check the tree in to my svn repository, including the CVS directories. I can commit all my changes, and still do a cvs update to stay up to date with bug fixes/features of the public project. How should I work on the svn project? Is there a 'best practice' or known procedure for this kind of scenario?

• Treeview DatafieldParentID Bind to Object whose property is a another object

  - by user228777

  I am trying to bind Generic collection to a Rad Treeview control. In following case CategoryCollection Returns collection of Category Object, which has bunch of properties and A Parent property which is a object and this parent object Has Id and text properties. What I am trying to do is: I want to Bind DataFieldParentID of the tree view to CategoryCollection.Parent.Id. How do I do that? Dim tvCategory As RadTreeView = DirectCast(cboCategory.Items(0).FindControl("tvCategory"), RadTreeView) With tvCategory .DataSource = CategoryCollection .DataTextField = "Name" .DataValueField = "ID" .DataFieldID = "ID" .DataFieldParentID = "Parent.ID" .DataBind() End With Thank You

• Automated user testing with times

  - by Sean

  I am attempting to test user interaction with an off the shelf product. The current process is to run through a manual script and record how long certain processes take to populate data, it may populate a datagrid, a tree, a list box, etc... It will also need to be able record how long it takes to generate a pdf report. We do not require extremely accurate time just to the nearest second or less than a second. I need to know if there is a simple Automated testing product that will handle the above criteria.

• Dataset and Hierarchial Data How to Sort

  - by mdjtlj

  This is probably a dumb question, but I've hit a wall with this one at this current time. I have some data which is hierarchial in nature which is in an ADO.NEt dataset. The first field is the ID, the second is the Name, the third is the Parent ID. ID NAME Parent ID 1 Air Handling NULL 2 Compressor 1 3 Motor 4 4 Compressor 1 5 Motor 2 6 Controller 4 7 Controller 2 So the tree would look like the following: 1- Air Handling 4- Compressor 6 - Controller 3 - Motor 2- Compressor 7- Controller 5 - Motor What I'm trying to figure our is how to get the dataset in the same order that ths would be viewed in a treeview, which in this case is the levels at the appropriate levels for the nodes and then the children at the appropriate levels sorted by the name. It would be like binding this to a treeview and then simply working your way down the nodes to get the right order. Any links or direction would be greatly appreciated.

• From my code, I can't trace the out of bounds exception.

  - by Matt

  public override Models.CalculationNode Parse(string expression) { var calNode = new Models.CalculationNode(); int i = expression.Length; char[] x = expression.ToCharArray(); string temp = ""; //Backwards assembly of the tree //Right Node while (!IsOperator(x[i]) && i > 0) { if (!x[i].Equals(' ')) temp = x[i] + temp; i--; } } It has been a while since I've used trees and I'm getting an out of bounds exception in the while loop.

• jQuery: How to hide all HTML elements which have a value greater than a certain value for a given ta

  - by Ankur

  I display elements in a hierarchy, clicking one displays the next set of elements in the hirearchy. Each element has a tag called "level" which has some value which is 1-.... (whatever the number of levels is for that branch of the tree). When an element is clicked I want the next elements to be displayed, but if an element is clicked and it's subelements have already been displayed I want to hide all subelements. More formally: when an element with level = x is clicked if no elements with level x are displayed then display all elements such that level = x+1 but if some elements with level x are displayed then hide all elements where level x How would I create a jQuery selector that captures this.

• Editing a TreeView node doesn't change the TreeNode Key

  - by Blitzz

  I have a TreeView with user-editable nodes. I like to use the node caption as key to my tree node : + Root |+ Node1 ||- SubNode1 ||- SubNode2 |+ Node2 ||- SubNode3 ||- SubNode4 So I can reach a node like this: MyTreeView.Nodes["Root"].Nodes["Node2"].Nodes["SubNode3"] The problem is that, as I allow the user to rename any node, I would need also to change the key of my node in its parent in the AfterLabelEdit handler... which seems (logically) not to be done automatically. Unfortunately, Nodes["blabla"] is readonly, Nodes.Add(string Key, TreeNode Node) doesn't exist, and I can't find a way to do this without throwing (sooner or later) a bad exception. Any idea ?

• Why is TreeSet<T> an internal type in .NET?

  - by Justin Niessner

  So, I was just digging around Reflector trying to find the implementation details of HashSet (out of sheer curiosity based on the answer to another question here) and noticed the following: internal class TreeSet<T> : ICollection<T>, IEnumerable<T>, ICollection, IEnumerable, ISerializable, IDeserializationCallback Without looking too deep into the details, it looks like a Self-Balancing Binary Search Tree. My question is, is there anybody out there with the insight as to why this class is internal? Is it simply because the other collection types use it internally and hide the complexities of a BST from the general masses...or am I way off base?

• Choosing the right and learning assembler for compiler-writing

  - by X A

  I'm writing a compiler and I have gone through all the steps (tokenizing, parsing, syntax tree structures, etc.) that they show you in all the compiler books. (Please don't comment with the link to the "Resources for writing a compiler" question!). I have chosen to use NASM together with alink as my backend. Now my problem is: I just can't find any good resources for learning NASM and assembly in general. The wikibook (german) on x86 assembly is horrible. They don't even explain the code they write there, I currently can't even get simple things like adding 1 to 2 and outputting the result working. Where can I learn NASM x86 assembly?

• (Visual) C++ project dependency analysis

  - by polyglot

  I have a few large projects I am working on in my new place of work, which have a complicated set of statically linked library dependencies between them. The libs number around 40-50 and it's really hard to determine what the structure was initially meant to be, there isn't clear documentation on the full dependency map. What tools would anyone recommend to extract such data? Presumably, in the simplest manner, if did the following: define the set of paths which correspond to library units set all .cpp/.h files within those to belong to those compilation units capture the 1st order #include dependency tree One would have enough information to compose a map - refactor - and recompose the map, until one has created some order. I note that http://www.ndepend.com have something nice but that's exclusively .NET unfortunately. I read something about Doxygen being able accomplish some static dependency analysis with configuration; has anyone ever pressed it into service to accomplish such a task?

• Implementing Tagging using Core Data on the iPhone

  - by Jonathan Penn

  I have an application that uses CoreData and I'm trying to figure out the best way to implement tagging and filtering by tag. For my purposes, if I was doing this in raw SQLite I would only need three tables, tags, item_tags and of course my items table. Then filtering would be as simple as joining between the three tables where only items are related to the given tags. Quite straightforward. But, is there a way to do this in CoreData and utilizing NSFetchedResultsController? It doesn't seem that NSPredicate give you the ability to filter through joins. NSPredicate's aren't full SQL anyway so I'm probably barking up the wrong tree there. I'm trying to avoid reimplementing my app using SQLite without CoreData since I'm enjoying the performance CoreData gives me in other areas. Yes, I did consider (and built a test implementation) diving into the raw SQLite that CoreData generates, but that's not future proof and I want to avoid that, too. Has anyone else tried to tackle tagging/filtering with CoreData in a UITableView with NSFetchedResultsController

• Problem with acceding 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.

• ASP.Net Treeview - Client side event handling (jQuery??)

  - by The Great Gonzo

  I have a Treeview (bog standard ASP.Net Treeview) that is bound to an Xml source which allows the user to navigate to various parts of our system. Nothing special.... However, I wanted to generate a breadcrumb for use in the main content area on the client side when the user clicks a node in the Treeview control. I know there are mechanisms available for breadcrumb generation (such as site maps) but for various reasons I need to do it when a node is clicked. So far hooking up a click event using the document ready function available as part of jQuery is easy. However, having spent sometime looking I can not see how I navigate back up the tree nodes to get to each parent nodes text value to build the breadcrumb. I have been playing with .parent(), .parents() and .closest() available via jQuery but don't seem to be getting anywhere. Has anyone done anything like this or can anyone provide a better method? Thanks in advance....

• .classpath and .project - check into version control or not?

  - by amarillion

  I'm running an open source java project that consists of multiple modules in a tree of dependencies. All those modules are subdirectories in a subversion repository. For newcomers to our project, it's a lot of work to set all that up manually in eclipse. Not all our developers use eclipse. Nevertheless, we're considering to just check in the .classpath and .project files to help newcomers to get started. Is this a good idea? Or would that lead to constant conflicts in those files? Is there an alternative way to make the project easy to set up on eclipse?

• Generic XML parser in Silverlight 3.0

  - by Ummar

  Hi I am developing an application in Silverlight 3.0, I want to make a generic parser of XML in it, as on every call to webservice I am receiving a different XML, I want to make it generic so that I receive an XML in native datastructure of C#? Please help me out? like I am getting XML like this one time <test> <node1></node1> <node2></node2> </test> and other time <mytest> <application name="XYZ">My Application</application> <application name="ABC">My Application</application> </mytest> I want the generic parser, e.g. it makes some tree structure of whole XML

• Can I pass events like key strokes to another control in Silverlight?

  - by herzmeister der welten

  Can I pass events like key strokes to another control in Silverlight? Imagine I'm in a custom control that contains a Textbox and a Treeview. I'm listening to a Key event for the TextBox. When the user pushes the Arrow Up or Arrow Down key, I want the Treeview to behave as if it's itself who received that event, i.e. it should move the current selection up or down. The user shouldn't lose focus on the TextBox though so that they can continue typing. Is this possible? I don't want to set the selection manually on the Treeview because it has no easy MoveSelectionUp() or MoveSelectionDown() method, so I would have to duplicate that functionality which is not so trivial especially when the tree is databound and loads nodes on demand.

• UINavigation controller problem

  - by VansFannel

  Hello. I'm developing an iPhone application and I'm trying to do this: I want an application with tree views. The view shown first, doesn't have a navigation bar. If the user tap on a button, I need to open the second view with a navigation bar and a table view. The user can also add new items to the table view. If the user do so, the application will show the third view where the user can add fields (this view has also a navigation bar). It may seem simple, but for me it is not. I don't know how to use the UINavigationController and have not found yet a similar example for what I do (paragraph translated by google). UPDATE I don't know how where to put UINavigationController. How can I do that? Can I use a UIViewController to call a UINavigationController? Thank you.

• Page fully rendered event?

  - by alex

  I'm altering the DOM tree in plain JS and need to know when the changes get fully rendered on screen (mostly care about document dimensions). window.onload=function(){ ss = document.styleSheets[0]; for(i = 0; i < ss.cssRules.length; i++) { ss.deleteRule(i) }; ss.addRule('p', 'color: red;') // ... many more // call some other function when the page is fully rendered? } TIA.

• 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.

• Git: Merge in only one commit

  - by Ivan

  Usually, I work with branches in Git, but I don't like to see hundreds of branches in my working tree (Git history). I'm wondering if there is a method in Git to "join" all commits in a branch in only one commit (ideally with a clear commit message). Something like this: git checkout -b branch <some work> git commit -a -m "commit 1" <some work> git commit -a -m "commit 2" <some work> git commit -a -m "commit 3" git checkout master git SUPER-JOIN branch -m "super commit" After this, only "super commit" will exist in the git log.

• Free object/widget in GTK?

  - by wag2639

  I've got a pack box in my GTK application and I'm replacing it every once in a while with a completely new entry (at least for now cause I'm in a hurry). Since I'm replacing it with a new instance, do I need to explicitly free from memory the old pack box contents or is there some garbage collection in GTK? If I do need to explicitly need to free the object, is there a command that will recursively go to all objects in that tree (like will it clear my button in a box container inside my main pack box)? I'm using C/GTK-2.0 (gcc v4.4.3 and GTK 2.20.0).

• Enable export to XML via HTTP on a large number of models with child relations

  - by Vasil

  I've a large number of models (120+) and I would like to let users of my application export all of the data from them in XML format. I looked at django-piston, but I would like to do this with minimum code. Basically I'd like to have something like this: GET /export/applabel/ModelName/ Would stream all instances of ModelName in applabel together with it's tree of related objects . I'd like to do this without writing code for each model. What would be the best way to do this?

• Git: Stage into Commit, what is the right workflow?

  - by Lukasz Lew

  I just created a big piece of code I want to commit in several separate commits. So I can stage relevant parts, commit, stage, commit, ... and so on until I have all my changes commited. The missing part is how can I test whether I split the commit correcty. I.e. whether the part that is in staging area at least compiles? To do that I must somehow bring my work tree to be in sync with index (staging area) without losing the changes to be committed later. What is the right way to do it? What is the quickest way to do it? Update: How to do it with magit?

• 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.
