  • Will Windows Update modify anything in Visual Studio?

    - by Martin
    (Note: Yes, the technical side of this question seems to be rather SuperUser, but the implications are more relevant for StackOverflow readers.) As the title says, we are wondering if (fully) enabling automated Windows Updates on our developer machines will have implications for MS Visual Studio. That is, will any fixes to any components (be it libraries, UI/IDE, compiler, ...) ever be updated through Windows Update? We want to have 100% exact and reproducible development environments (wrt C++) on all developer machines, and so we are concerned that automated Windows updates may introduce some uncontrolled updates into our development chain.

  • Refactoring Rails 3 Routes

    - by Martin
    Hello, I have this in my routes: get '/boutique/new' => 'stores#new', :as => :new_store, :constraints => { :id => /[a-z0-9_-]/ } post '/boutique' => 'stores#create', :as => :create_store, :constraints => { :id => /[a-z0-9_-]/ } get '/:shortname' => 'stores#show', :as => :store, :constraints => { :id => /[a-z0-9_-]/ } get '/:shortname/edit' => 'stores#edit', :as => :edit_store, :constraints => { :id => /[a-z0-9_-]/ } put '/:shortname' => 'stores#update', :as => :update_store, :constraints => { :id => /[a-z0-9_-]/ } delete '/:shortname' => 'stores#delete', :as => :destroy_store, :constraints => { :id => /[a-z0-9_-]/ } Is there a cleaner way to do the same? It doesn't look any elegant and even less if I add some more controls/actions to it. Thank you.

  • WCF consumed as WebService adds a boolean parameter?

    - by Martín Marconcini
    I've created the default WCF Service in VS2008. It's called "Service1" public class Service1 : IService1 { public string GetData( int value ) { return string.Format("You entered: {0}", value); } public CompositeType GetDataUsingDataContract( CompositeType composite ) { if ( composite.BoolValue ) { composite.StringValue += "Suffix"; } return composite; } } It works fine, the interface is IService1: [ServiceContract] public interface IService1 { [OperationContract] string GetData( int value ); [OperationContract] CompositeType GetDataUsingDataContract( CompositeType composite ); // TODO: Add your service operations here } This is all by default; Visual Studio 2008 created all this. I then created a simple Winforms app to "test" this. I added the Service Reference to my the above mentioned service and it all works. I can instanciate and call myservice1.GetData(100); and I get the result. But I was told that this service will have to be consumed by a Winforms .NET 2.0 app via Web Services, so I proceeded to add the reference to a new Winforms .NET 2.0 application created from scratch (only one winform called form1). This time, when adding the "web reference", it added the typical "localhost" one belonging to webservices; the wizard saw the WCF Service (running on background) and added it. When I tried to consume this, I found out that the GetData(int) method, was now GetData(int, bool). Here's the code private void button1_Click( object sender, EventArgs e ) { localhost.Service1 s1 = new WindowsFormsApplication2.localhost.Service1(); Console.WriteLine(s1.GetData(100, false)); } Notice the false in the GetData call? I don't know what that parameter is or where did that come from, it is called "bool valueSpecified". Does anybody know where this is coming from? Anything else I should do to consume a WCF Service as a WebService from .NET 2.0? (winforms).

  • Seperating two graphs based on connectivity and coordinates

    - by martin
    I would like to separate existing data of vertices and edges into two or more graphs that are not connected. I would like to give the following as example: Imagine two hexagons on top of each other but are lying in different Z. Hexagon 1 has the following vertices A(0,0,1), B(1,0,2), C(2,1,2), D(1,2,1), E(0,2,1), F(-1,2,1). The connectivity is as following: A-B, B-C, C-D, D-E, E-F, F-A. This part of Graph 1 as all the vertices are connected in this layer. Hexagon2 has the following vertices A1(0,0,6), B1(1,0,7), C1(2,1,7), D1(1,2,8), E1(0,2,7), F1(-1,2,6). The connectivity is as following: A1-B1, B1-C1, C1-D1, D1-E1, E1-F1, F1-A1. This is part of Graph 2 My data is in the following form: list of Vertices and list of Edges that i can form graphs with. I would like to eliminate graph 2 and give only vertices and connectivity of graph 1 to polygon determination part of my algorithm. My real data contains around 1000 connected polygons as graph 1 and around 100 (much larger in area) polygons as graph 2. I would like to eliminate graph 2. I am programming this in python. Thanks in advance.

  • How to declare class attributes in swift, just like UITableViewCell reuse identifiers?

    - by martin
    I am trying to declare a reuse identifier associated to a UITableView subclass in swift. From my understanding I would like to declare an class stored property (not an instance one) so i have access via: MyCustomTableCell.ReuseIdentifer. Here is what I was trying: class MyCustomTableViewCell : UITableViewCell { class let ReuseIdentifier = "MyCustomTableViewCellReuseIdentifier" } The compiler mentions that class attributes are not supported yet. How to declare such kind of constants associated to a class type in a clean way?

  • SQL Server float datatype

    - by Martin Smith
    The documentation for SQL Server Float says Approximate-number data types for use with floating point numeric data. Floating point data is approximate; therefore, not all values in the data type range can be represented exactly. Which is what I expected it to say. If that is the case though why does the following return 'Yes' in SQL Server DECLARE @D float DECLARE @E float set @D = 0.1 set @E = 0.5 IF ((@D + @D + @D + @D +@D) = @E) BEGIN PRINT 'YES' END ELSE BEGIN PRINT 'NO' END but the equivalent C++ program returns "No"? #include <iostream> using namespace std; int main() { float d = 0.1F; float e = 0.5F; if((d+d+d+d+d) == e) { cout << "Yes"; } else { cout << "No"; } }

  • Is a safe accumulator really this complicated?

    - by Martin
    I'm trying to write an accumulator that is well behaved given unconstrained inputs. This seems to not be trivial and requires some pretty strict planning. Is it really this hard? int naive_accumulator(unsigned int max, unsigned int *accumulator, unsigned int amount) { if(*accumulator + amount >= max) return 1; // could overflow *accumulator += max; // could overflow return 0; } int safe_accumulator(unsigned int max, unsigned int *accumulator, unsigned int amount) { // if amount >= max, then certainly *accumulator + amount >= max if(amount >= max) { return 1; } // based on the comparison above, max - amount is defined // but *accumulator + amount might not be if(*accumulator >= max - amount) { return 1; } // based on the comparison above, *accumulator + amount is defined // and *accumulator + amount < max *accumulator += amount; return 0; }

  • How to change security configutarion in IE8 for Intranet pages, such that Javascript can close a Win

    - by Martín Fixman
    I am developing a system that uses a little Internet page as a front-end for the whole program. Since I need to use ActiveX (sigh), the page must work on Internet Explorer. However, after some actions have been done the page needs to close itself. Using window.close() on Javascript it works, but before closing it prompts the user if it wants to close the Window. The ideal would be that it closes automatically. Is there any way to make IE8 (changing an option on the browser, not a code-only solution) not to prompt before closing the Window?

  • How do I take a copy of my working copy to share with others?

    - by Martin
    I did a ton of changes to our code and before I commit, I would like a friend to review. Is there a way with SVN to take a copy of my working copy (to bundle everything in a package) and apply the changes I have made so far to another machines without having to commit? In the past, with another source control system, I was able to do the following to "pack" and "unpack" my changes. Is there anything similar with SVN? sourcecontrol.exe pack myChanges.pack sourcecontrol.exe apply myChanges.pack Thanks!

  • How do I set a static bool in another app domain?

    - by Martin
    How do I programatically set the value of a static boolean in another app domain? I'm testing an application where I need to change a bool value. Problem is that the bool value exists as a static instance on a type hosted in another app domain. (I'm doing this for test purposes, it won't be used in production code)

  • git, SSH_ASKPASS on windows

    - by Martin Schreiber
    I am writing a graphical git frontend for Linux and Windows (MSEgit) based on MSEide+MSEgui. MSEgit has an internal console window which communicates with git by pipes. On Linux it uses a PTY so SSH asks for key unlocking passwords on the PTY. On Windows I wrote a small password entry application and set the SSH_ASKPASS environment variable accordingly. SSH calls the password application if git is started with CreateProcess() dwCreationFlags DETACHED_PROCESS set but the password entry window will not be focused, its taskbar icon flashes instead. SSH does not run the password application if FreeConsole() is called to be sure that there is no attached console to MSEgit and git is started without DETACHED_PROCESS but CREATE_NO_WINDOW instead. I assume a Windows equivalent of POSIX setsid() should be called. How can I force SSH to use SSH_ASKPASS without the DETACHED_PROCESS flag? If this is not possible, how can I ensure that the password entry window is focused?

  • What is the best way to write faster on Vim using a non-english keyboard?

    - by Martín Fixman
    I usually use Vim, and its great for the ability to do faster some actions than other editors. However, since I live in Argentina I have a Latin American keyboard, that makes everything in Vim pretty slower (to write / to search, I must press Shift+7). Since I don't want to be changing Keyboard layouts all the time (and its pretty difficult to get used to pressing symbols as in an English keyboard), I was wondering if there was a vim plugin (of .vimrc file) that may be useful for international users. Just for the sake of it, here's how the Latin American keyboard is laid out: By the way, I would love to go and buy an English keyboard, but unfortunately I use a Laptop.

  • Compiling my Boost/NTL program with c++ on Linux.

    - by Martin Lauridsen
    Hi SO, I wrote a client program and a server program, that uses the NTL library and Boost::Asio, to do client/server communication for an integer factorization application, in C++. Both sides consist of several headers and cpp files. Both project compile fine individually on Windows in Visual Studio. All I did, was add the include path of NTL and Boost to both projects: Additional include paths: "D:\Downloads\WinNTL-5_5_2\include";D:\boost_1_42_0 Furthermore, for both projects, I added the two library paths to both projects in VS: Additional library directories: D:\boost_1_42_0\stage\lib;"D:\Documents\Visual Studio 2008\Projects\ntl\Debug" And added under Additional dependencies: ntl.lib As said, it compiles fine on Windows. But when I put the code on a Linux machine provided by university, I try to compile with the following statement c++ -I/appl/htopopt/Linux_x86_64/NTL-5.4.2/include -I/appl/htopopt/Linux_x86_64/boost_1_43_0/include client_protocol.cpp mpqs_client.cpp mpqs_sieve.cpp mpqs_helper.cpp -o mpqs_helper -L/appl/htopopt/Linux_x86_64/NTL-5.4.2/lib -lntl -L/appl/htopopt/Linux_x86_64/gmp-4.2.1/lib -lgmp -lm -L/appl/htopopt/Linux_x86_64/boost_1_43_0/lib -lboost_system -static Upon doing this, I get a huuuge error, which I posted here. Any idea how to fix this, please??

  • HashMap as return value from Java method in R?

    - by Martin
    Hi, is it possible to return a HashMap to R with the rJava extension of R? E.g. I have a method in Java, which returns a HashMap and I want this HashMap use in R. I tried: .jcall(javaObj, "Ljava/util/HashMap", "getDbInfoMap") This doesn't work. Do I have to put everything into a String[], that I want to pass to R from Java? Or is there another possibility? Any help/info on this would be greatly appreciated.

  • Git: Make one branch exactly like another

    - by G. Martin
    I am relatively new to Git, and I'm still not very comfortable with it. Right now, I'm looking for the command/options/magic that can make the current branch look like another branch; that is, to merge them, but when a conflict arises, to always choose the difference in the branch that is being merged into the current one. My situation is thus; I have an stable(ish) application on the "master" branch. I also have another branch, called "feature". I basically want to make changes/additions/deletions to feature until I like the new feature I'm working on. Once I feel it is ready, I want to make the master branch look identical to the feature branch. I know this probably isn't a best practice, but as I said, I'm new to Git. I plan on learning how to do more complicated things in the future, but for now, this is all I need. Thanks, SO!

  • Do I need to syncronize thread access to an int

    - by Martin Harris
    I've just written a method that is called by multiple threads simultaneously and I need to keep track of when all the threads have completed, the code uses this pattern: private void RunReport() { _reportsRunning++; try { //code to run the report } finally { _reportsRunning--; } } This is the only place within the code that _reportsRunning's value is changed, and the method takes about a second to run. Occasionally when I have more than six or so threads running reports together the final result for _reportsRunning can get down to -1, if I wrap the calls to _runningReports++ and _runningReports-- in a lock then the behaviour appears to be correct and consistant. So, to the question: When I was learning multithreading in C++ I was taught that you didn't need to synchronize calls to increment and decrement operations because they were always one assembly instruction and therefore it was impossible for the thread to be switched out mid-call. Was I taught correctly, and if so how come that doesn't hold true for C#?

  • Adding to a bit array

    - by Martin
    In my program, I am using BitArrays to represent 160 bit numbers. I want to be able to add, subtract, increment and decrement these numbers, what is the algorithm for doing this? At the moment I'm not interested in multiplication and division, but I might be in the future so bonus points for that. I'm implementing in C#, but pseudocode is fine if you're not familiar with the language

    Hi, I'm now using AxWebBrowser component to get DOM from web page and find used styles on each element. Unfortunatelly this is not working perfectly and some elements doesn't return correct data. I'm thinking about if it's possible to use engine from firefox? Is there some dll library I can use, navigate to the page and go throw DOM of the page?
