• How do you update the server name in source indexed symbol file?

  - by Keith Hill

  With the Debugging Tools for Windows you can run SSIndex.cmd against your symbol files and it will embed the command to retrieve each source code file from the TF server. We have a bunch of indexed files and recently our IT migrated our TFS 2008 installation to TFS 2010 and in the process changed the server name. Question is, how can I update all these symbol files to point to the new server? I thought SSindex used an alternate data stream named 'srcsrv' but SysInternals' streams.exe shows nothing on these symbol files even though srctool.exe shows the data.

• Is there a way to circumvent CA1726:UsePreferredTerms?

  - by klausbyskov

  I have a problem with the code analysis rule CA1726:UsePreferredTerms. Our business domain has two crucial concepts named Case and Flag. According to CA, it's apparently a deadly sin to use these names, however I really don't care since, as I said, they are crucial concepts in our domain model. CA complains not only about the type declarations but about every method parameter-name aswell. So does anyone know if there is a workaround other than adding loads of suppressions or disabling the rule altogether? Could I add the names to a custom dictionary?

• Windows batch file to list folders that have a specific file in them

  - by Lee

  I'm trying to create a file that has a list of directories that have a specific file name in them. Let's say I'm trying to find directories that have a file named *.joe in them. I initially tried just a simple dir /ad *.joe > dir_list.txt , but it searches the directory names for *.joe, so no go. Then I concluded that a for loop was probably my best bet. I started with for /d /r %a in ('dir *.joe /b') do @echo %a >> dir_list.txt and it looked like it wasn't executing the dir command. I added the "usebackq", but that seems to only work for the /F command extension. Ideas?

• ASP.NET - Themes and Relative Referencing

  - by user70192

  Hello, I have an ASP.NET application that uses themes. Let's pretend I have a theme named "MySkin". I have a page that is in a sub-directory of my application. When I reference a page that uses "MySkin", I noticed that ASP.NET renders a link element that walks up to the root of the site and then down into the App_Themes directory. Here is an example link element I found in a rendered ASP.NET page: <link href="../../App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is there a reason that the rendered link element does not use the following instead: <link href="/App_Themes/MySkin/theme.css" type="text/css" rel="stylesheet" /> Is this a browser compatibility issue or is there another reason? The reason I am asking is because I am rendering my ASP.NET page using Server.Execute and storing the result in a different directory. Because of this, I would prefer to use the second way to reference my theme's css. Thank you!

• Ruby get inheriting class

  - by Brian D.

  I'm working on creating my first plugin for rails. I'm still pretty new to ruby and I was wondering if its possible to get the inheriting class? For example, I'm trying to create a plugin that will allow unit testing and functional testing when you are not using migrations. What I'm trying to do is initialize a class variable named controller to be initialized to the type of controller that is being tested. If I have a base class ControllerTest: class ControllerTest < Test::Unit::TestCase attr_accessor :controller def initialize super @controller = "call function that will find the inheriting classes name and create an instance of that controller type." end end So what I'm currently stuck on is getting the name of the inheriting class. Is this possible? And if not, does anyone know another way on how I could go about implementing this? Thanks in advance.

• Python script shows different pythonpath

  - by Bird Jaguar IV

  Attempting to run runsnake gives ImportError: No module named wx Opening an ipython or python session seems to work fine: >>> import wx >>> import sys >>> print [p for p in sys.path if 'wx' in p] ['/usr/local/lib/wxPython-2.9.4.0/lib/python2.7/site-packages', '/usr/local/lib/wxPython-2.9.4.0/lib/python2.7/site-packages/wx-2.9.4-osx_cocoa', '/usr/local/lib/wxPython-2.9.4.0/lib/python2.7/site-packages/wx-2.9.1-osx_cocoa/tools'] as does putting that code in a script and calling python script.py. But putting that code at the beginning of runsnake.py prints an empty list (printing the whole sys.path prints a path quite different from my $PYTHONPATH). Why would it be different, and how to I get it to recognize wxPython?

• Java Spring 3.0 MVC Annotation vs COC. Whats the preferred method in the Java community?

  - by Athens

  I am using Spring's MVC framework for an application I'm hosting on Google's App Engine. So far, my controllers are registered via the @Controller annotation; however, prior to getting into Spring, I evaluated ASP.net MVC 2 which requires no configuration and is based on convention. Is convention over configuration (COC) the current and preferred method in the Java community to implement MVC with Spring. Also, this may be a result of my limited knowledge so far but i noticed that i could only instantiate my Controllers the required constuctor injection if i use the COC method via the ControllerClassNameHandlerMapping. For instance the following controller bean config will fail if i use the defaultannotationhandlermapping. <bean id="c" class="com.domain.TestController"> <constructor-arg ref="service" /> </bean> <bean id="service" class="com.domain.Service" /> My com.domain.TestController controller works fine if i use ControllerClassNameHandlerMapping/COC but it results in an error when i use defaultannotationhandlermapping/Annotations.

• T-SQL error object exists when separated in if/else blocks

  - by Jeff O

  I get the error: Msg 2714, Level 16, State 1, Line 16 There is already an object named '#mytemptable' in the database. There are ways around it, but wonder why this happens. Seems like SQL Server is verifying both blocks of the if/else statement? declare @choice int select @choice = 1 if @choice = 1 begin select 'MyValue = 1' AS Pick into #my_temp_table end else begin select 'MyValue <> 1' AS Pick into #my_temp_table end select * from #temptable drop table #temptable If the tables have different names, it works. Or if I create the temp table and use Insert Into... statements that works as well.

• C# property definition

  - by Sunny

  For C# properties, I can do this: public class Employee{ public string Name { get; private set; } public Employee(string name){ Name = name; } } which means that the Name property can be set within the class Employee & can be read publicly. But, if I want to restrict the set to only within the constructors of the Employee class, I need to do: public class Employee{ public readonly string Name = String.Empty; public Employee(string name){ Name = name; } } But, for this case, I had to change the property to a field. Is there any reason this is not possible/allowed in C#: public class Employee{ public string Name { get; private readonly set; } public Employee(string name){ Name = name; } } IMO this will allow us to have properties which can be set only in the constructor & does not require us to change properties to fields... Thanks!

• Handling duplicate nodes in XML

  - by JYelton

  Scenario: I am parsing values from an XML file using C# and have the following method: private static string GetXMLNodeValue(XmlNode basenode, string strNodePath) { if (basenode.SelectSingleNode(strNodePath) != null) return (basenode.SelectSingleNode(strNodePath).InnerText); else return String.Empty; } To get a particular value from the XML file, I generally pass the root node and a path like "parentnode/item" I recently ran into an issue where two nodes at the same document level share the same name. Question: What is the best way to get the values for duplicate-named nodes distinctly? My thought was to load all values matching the node name into an array and then using the array index to refer to them. I'm not sure how to implement that, though. (I'm not well-versed in XML navigation.)

• Kohana 3 ORM limitations

  - by yoda

  Hi, What are the limitations of Kohana 3 ORM regarding table relationships? I'm trying to modify the build-in Auth module in order to accept groups of users in adition, having now the following tables : groups groups_users roles roles_groups users user_tokens By default, this module is set to work without groups, and linking the users and roles using a third table named roles_users, but I need to add groups to it. I'm linking, as you can see by the names, the groups to users and the roles to groups, but I'm failing building the ORM code for it, so that's pretty much the question here, if ORM is limited to 2 relationships or if it can handle 3 in this case. Cheers!

• How to return radio checked object with jQuery ?

  - by Kim

  HTML <input type="radio" name="rdName" id="uniqueID1" value="1" checked="checked"> <input type="radio" name="rdName" id="uniqueID2" value="2"> <input type="radio" name="rdName" id="uniqueID3" value="3"> jQuery #1 $('input:radio[name=rdName]:checked').val(); jQuery #2 $('input[name=rdName]:checked'); jQuery #1 gets the value of checked radio, but I need to get the whole object to get the ID. jQuery #2 get this (from Chrome Dev console). Object "0" is the actual object I need, but I am unable to just that. 0: HTMLInputElement constructor: function Object() context: HTMLDocument length: 1 prevObject: Object selector: input[name=rdName]:checked __proto__: Object Any ideas how to isolate the needed object ?

• C++ Linked List - Reading data from a file with a sentinel

  - by Nick

  So I've done quite a bit of research on this and can't get my output to work correctly. I need to read in data from a file and have it stored into a Linked List. The while loop used should stop once it hits the $$$$$ sentinel. Then I am to display the data (by searching by ID Number[user input]) I am not that far yet I just want to properly display the data and get it read in for right now. My problem is when it displays the data is isn't stopping at the $$$$$ (even if I do "inFile.peek() != EOF and omit the $$$$$) I am still getting an extra garbage record. I know it has something to do with my while loop and how I am creating a new Node but I can't get it to work any other way.

• Program to call other programs

  - by Evil

  hello. I am writing a program that will solve a type of min. spanning tree problem. i have 2 different algorithms that I've gotten working in two separate .cpp files i've named kruskels.cpp and prims.cpp. my question is this: each file takes the following command line to run it . time ./FILENAME INPUTFILE FACTOR i would like to make a program that, depending on what inputfile is entered, will run either kruskels.cpp or prims.cpp. how can i do this? this program must pass those command line arguments to kruskels or prims. each file (kruskels.cpp and prims.cpp) are designed to be run using those command line arugments (so they take in INPUTFILE and FACTOR as variables to do file io). this should be for c++.

• Maximum Possible File Name Length in Windows Kernel

  - by Lambert

  I was wondering, what is the longest possible name length allowed by the Windows kernel? E.g.: I know the kernel uses UNICODE_STRING structures to hold all object paths, and since the byte length of a wide-character string is stored inside a USHORT, that allows for a maximum path length of 2^15 - 1 characters. Is there a similar, hard restriction on a file name (rather than path)? (I don't care if NTFS or FAT32 imposes a particular restriction; I'm looking for the longest possible theoretically allowed name in the kernel, assuming no additional file system or shell restrictions.) (Edit: For those wondering why this even matters, consider that normally, traversing a directory is achieved by FindFirstFile/FindNextFile calls, one call per file. Given the function named NtQueryDirectoryFile, which is the underlying system call and which returns multiple file names per call, it's actually possible to take advantage of this maximum-length restriction on the path to make an extremely-fast directory traverser that uses solely the stack as a buffer. Now I'm trying to extend that concept, and I need to know the maximum size of a file name.)

• Correctly Applying an Open Source License

  - by Johannes Rudolph

  My question consists of multiple points that are inherently related, I apologize for that. I tried splitting it up a little more, but I would keep repeating myself. What exactly is required to apply an open source license to a code base that is my Intellectual Property? A lot of Open Source projects include a full copy of the license somewhere in a root directory but do also have some sort of file header including a license description, disclaimer and a copyright notice. Is that really necessary or does it depend on the license type? If someone else contributes changes to this file, does he need to be named in the copyright notice too?

• PHP & MySQLi timeout

  - by Dt7

  Whenever I try to create a mysqli object, as in; $mysqli = new mysqli(host, user, pass, table); ...the page just loads for around a minute, then stops, showing all the content of the page up until that line. info() says that MySQLi (and MySQL if that matters) are enabled, and I can access the MySQL CLI. I'm also working on a local machine, not a remote server. I feel like I've missed something obvious. Can anyone shed some light on it? Edit: just for clarification, I am actually putting real values into the mysqli constructor :)

• How to configure git repository so a branch other than master is checked out after a cloning?

  - by Suraj Barkale

  I am trying to set up a git server with bunch of repositories. I am planning to use the branching model described in http://nvie.com/git-model article. So I will have at least two branches (named master and develop) in the repository. After a clone the master branch is checked out by git. Is there a git config option so that develop branch will be checked out instead? In effect I want git clone my_repo_url to behave as git clone -b develop my_repo_url.

• In Prism (CAL), how can I RegisterPresenterWithRegion instead of RegisterViewWithRegion

  - by Edward Tanguay

  I have a module in a Prism application and in its initialize method I want to register a presenter instead of a view with a region, i.e. I want to do this: PSEUDO-CODE: regionManager.RegisterPresenterWithRegion( "MainRegion", typeof(Presenters.EditCustomerPresenter)); instead of loading a view like this: regionManager.RegisterViewWithRegion( "MainRegion", typeof(Views.EditCustomerView)); The presenter would of course bring along its own view and ultimately register this view in the region, but it would allow me to bind the presenter to the view in the presenter's constructor instead of binding the two together in XAML (which is more of a decoupled MVVM pattern which I want to avoid here). How can I add a Presenter to a Region instead of a view? namespace Client.Modules.CustomerModule { [Module(ModuleName = "CustomerModule")] public class CustomerModule : IModule { private readonly IRegionManager regionManager; public CustomerModule(IRegionManager regionManager) { this.regionManager = regionManager; } public void Initialize() { regionManager.RegisterViewWithRegion("MainRegion", typeof(Views.EditCustomerView)); } } }

• ADT will not allow creation of Android Activity

  - by NewShelbyWoo

  I installed the ADT bundle from http://developer.android.com/sdk/index.html yesterday, and I was following a basic Hello World tutorial. I created a new Android Application Project with a Blank Activity named MainActivity. The resulting project has an empty src folder and empty res\layout folder. There is a R.java file in the gen folder but it has no reference to MainActivity. This is what the SDK manager says I have installed Android SDK Tools v 22.6 Android SDK Platform-tools v 19.0.1 Android SDK Build-tools v 19 SDK Platform v 3 ARM EABI v7a System Image v 2 Android Support Library v 19.0.1 Google USB Driver v 9 I also tried manually creating an activity by right clicking the src folder and going to Android Activity, but when I hit Finish on the creation wizard, nothing happens. Does anyone have any clues as to what's going on? Did I miss a key component to install or something?

  I am writing a big C code... The code includes recursive bactracking function named Branch() that is called so much... My goal is to write the fastest code to get the best running time... I also have another function Redundant() void Redundant() { int* A; A=(int*)malloc(100*sizeof(int)); } I created two versions. Version A: Redundant() is included in Branch(). Version B: Redundant() is not included in Branch() A run 10 times faster than B !!!! Is is Magic or is it kind of process scheduling or what ??

• What parameters should I use in a Google Maps URL to go to a lat-lon?

  - by xpda

  I would like to produce a url for Google Maps that goes to a specific latitude and longitude. Now, I generate a url such as this: http://maps.google.com/maps?z=11&t=k&q=58 41.881N 152 31.324W The resulting map comes up with a round "A" balloon pointer, which seems to point to the nearest named object, and a green arrow, which points to the lat-lon. Sometimes, as in this example, the "A" pointer is centered and is far enough away that you cannot see the pointer to the lat-lon. (Zoom out to see both pointers in this example. The "A" pointer is in the center of Alaska, while the lat-long pointer is on Kodiak Island.) Are there some parameters I can use in the Google Maps URL that will produce a single pointer to a designated lat-lon? (This loads in a separate window. It is not embedded.)

• Java: constructing a file from a URI?

  - by AP257

  I need to obtain a File object from a URI, working in Java, but keep getting a length of zero - though I know the file size is not zero. I need the File object to pass to another constructor. I'm not sure if it's because I'm constructing it in the wrong way? Here's my code: File videoFile = new File(videoURI.getPath()); if (videoFile == null) { Log.d(LOG_TAG, "File not found!"); return false; } Log.d(LOG_TAG, "about to upload, filepath: " + videoFile.getPath()); Log.d(LOG_TAG, "File length: " + String.valueOf(videoFile.length())); The log output doesn't spit out 'File not found!', and prints a non-null path, but shows a length of 0.

• What is the correct method to load an XML file and re-write it as a CSV?

  - by codesmack

  I have a XML file that I want to load into an unknown object type. (I say unknown object type because I am not sure what direction to go) Once I have the data loaded I need to do some processing on certain elements that are now loaded into the new object. For sake of example, we can say that the xml file is full of elements named <car> and within the car element I need to process the <mileage> element. Then once this is all done I need to write the file as a CSV file. I would like to do this is the most direct way possible. (The less code the better) I am using VS 2008 C#
