  • Problem in reading configuration file from Class library project

    - by Newbie
    If I create an app.config file in a console apps like this <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key ="key1" value ="val1"/> </appSettings> </configuration> and access the same from the console application like object sourcePath = System.Configuration.ConfigurationManager.AppSettings["key1"]; or by object sourcePath = System.Configuration.ConfigurationSettings.AppSettings["key1"]; I am able to get the value. But if I do the same thing in a class library project, I am getting a null value. Why? Where I am making mistake? I have added the proper reference System.Configuration. I am using C# 3.0

  • Problem with access to file

    - by phenevo
    Hi, I have winforms application and it has reference to library MyLibrary. MyLibrary has method: string[] GiveMeNamesOfAirports() { string[] lines= File.ReadLines("airports.txt"); foreach(string line in lines) ... } And when I run my Winforms application: I get error: file couldn't be find. I was trying other function: string[] lines = File.ReadAllLines(Path.Combine(System.Environment.CurrentDirectory, "airports.txt")); string[] lines = File.ReadAllLines(Path.Combine(Assembly.GetExecutingAssembly().Location, "airports.txt")); string[] lines = File.ReadAllLines(Path.Combine(Assembly.GetAssembly(typeof(Airport)).Location, "airports.txt"));

  • Create categorial variable in R based on range

    - by Stedy
    I have a dataframe with a column of integers that I would like to use as a reference to make a new categorical variable. I want to divide the variable into three groups and set the ranges myself (ie 0-5, 6-10, etc). I tried cut but that divides the variable into groups based on a normal distribution and my data is right skewed. I have also tried to use if/then statements but this outputs a true/false value and I would like to keep my original variable. I am sure that there is a simple way to do this but I cannot seem to figure it out. Any advice on a simple way to do this quickly?

  • Missing type or namespace name

    - by Psytronic
    This is an odd one, not one I've come across before. My project complies and runs fine if I have my classes in the root folder (Not in App_Code). As soon as I move them into the App_Code folder then it will compile, but running it will bring up the old CS0234: The type or namespace name 'Linq' does not exist in the namespace 'System.Data' (are you missing an assembly reference?) I don't understand how moving the class(es) to the App_Code folder causes the whole thing to fall apart there? Project target is .Net 4 on VWD 2010 Express

  • SQL Server Reporting Services using of pictures with dynamic links

    - by YvesR
    I have setup a SSRS 2008 and building reports. So far so good. Now there is a picture control in SSRS where you can set the picture as external link reference. There you can choose to use a link. When I use a weblink (http://anyurl/download_picture.aspx?id=123) it dont' work for me. Calling the url in the web browser (all tested IE, Safari, Chrome, FF) the pictures is delivered, Header is ok, content type, too. Does it work in general in SSRS ? Or do I have to copy the picture to a temp folder and link the url like http://anyurl/mypicture.jpg.

  • Accessing and encoding of properties files

    - by NoozNooz42
    I'm used to work with properties files, for example from Ant. Where I can simply reference the property file doing something like that: <property file="webapp_DO_NOT_COMMIT.properties"/> (the file is so named because our DVCS is configured as to never commit files containing "DO_NOT_COMMIT" to prevent committing credentials/passwords/etc.) Here's a very simple .properties file example: passwd=brokencleartextpassword Now I want to put some configuration in another, similar, properties file that I need to access from my Java code. How should I go about it? I also have another related question: is the character encoding of .properties file defined by any spec?

  • Caveates on the html options of <pre> <code> [on hold]

    - by user2935199
    Over at html syntax to display literal string i asked about displaying a literal. When i tried : http://sdrv.ms/1bEsPWz (as the posted sample will not display, i need to show a picture, as i don't have 10 xxx, i can't insert a picture, I am only left with a skydrive reference) In english, the and syntax was tried but it failed to show all content inside the block. It only showed the "is equal to - pre sample " part. I thought - did not care what was inside ? Can some explain how to make a truely literal block display ? I have my reasons why i don't want to have the " syntax in the html. Thanks

  • Bundling images with Blackberry

    - by Casebash
    How do I get bundled images with the BlackBerry Eclipse Plugin 1.1 Beta? I copied an image into "res/background.jpg" and tried to load it using Bitmap.getBitmapResource on background.jpg. Unfortunately, the image wasn't found (Illegal argument exception). I tried moving my image file into the src folder as per the advice here, but that didn't work either. I have opened up the .jar file and the background image is present at the root of the .jar file. The option to convert image files to .png isn't selected either. Links Could not find sample Library Reference

  • Can I get.seed() somehow?

    - by a different ben
    In reference to the statement set.seed(), can I get the seed instead after running some code if I didn't set it explicitly? I've been re-running some code containing a function that randomises some sample of the input data (the function is part of the kohonen package). After playing with it for some time to see the variety of output (it was an 'unstable' problem), I noticed one result that was pretty interesting. I of course had not used set.seed(), but wondered if I could get the seed after running the code to reproduce the result? In ?set.seed I see .Random.seed saves the seed set for the uniform random-number generator But I don't know how that helps.

  • Using PHP's exec() function (or the likes), how can you display terminal error output?

    - by Miciah Amberong
    Previous Reference I am just wondering if there's a way (using PHP) to output the compile error information from the terminal to the browser? For example: If you use this code to execute in the terminal... gcc -o try try.c ...and assuming the "try.c" have some errors. The terminal will output something like this: try.c In function 'main': try.c:27 'x' undeclared (first use in this function) try.c:27 (Each undeclared identifier is reported only once try.c:27 for each function it appears in.) Meanwhile, using this PHP code... <?php exec("gcc -o try try.c"); ?> The browser does not return any output like the terminal does. Is there a possible way direct or indirect that the error details that the terminal showed can be passed to the be displayed on a browser? Thank you very much.

  • NHibernate: References still being eagerly selected after specifying AddJoin

    - by cbp
    I have a query which is something like this: Session.CreateSQLQuery( @"SELECT f.*, b.*, z.* FROM Foo f LEFT OUTER JOIN Bar b ON b.Id = f.BarId LEFT OUTER JOIN Zar z ON z.Id = b.ZarId" ) .AddEntity("f", typeof(Foo)) .AddJoin("b", "f.BarId") .AddJoin("z", "f.ZarId") .List<Foo>(); The problem is that I am still getting hundreds of SELECT requests made to the Zar table, even though I have specified that Zar should be joined. As far as I am aware the only relationship is Foo-Bar-Zar, i.e. the reference to Zar is not occurring anywhere else. Is my understanding of AddJoin correct? What could be going wrong? List item

  • merging 3 source versioned trees into 1

    - by user309779
    This is probably an easy question... I have 4 source versions of the same software in 4 different directories. I have just started using git for version control. To date, I have just been snapping a desperate copy rolling forward. I want to merge all versions (1.0.0.1, 1.0.0.2, 1.0.0.3, 1.0.1.0) together so that I will have a reference history. Opposed to just starting out with 1.0.1.0 as the initial version. I want to get this sort of thing right form the start. Can someone outline the basic steps to accomplish this? Thanks much, XO

  • How to launch an external application on BN_CLICKED?

    - by Alienexist
    I'm fairly new to Windows programming. I'm doing a simple launcher app for WinCE using VC++ (not MFC). So far I've created the basic interface and buttons and stuff. I just wanted to know the best way to launch an external application when the user clicks the button (on BN_CLICKED). I found some methods such as ShellExecute, CreateProcess and others. But I couldn't get it to work (yet?). Any suitable reference or simple example on this?

  • PHP callback function not being called

    - by Industrial
    Hi everyone, I've got the following code: function _callback_memcache_failure($host, $port) { print "memcache '$host:$port' failed"; } $this->memcache = new Memcache; $this->memcache->addServer('192.168.1.35', '11211', 0, 50, 10, TRUE, _callback_memcache_failure('192.168.1.35','11211')); The server is online and running (verified!), but the Failure callback function is being called at each connection. Why is that? Reference: PHP documentation: Memcache::addServer - failure_callback Allows the user to specify a callback function to run upon encountering an error. The callback is run before failover is attempted. The function takes two parameters, the hostname and port of the failed server .

  • Some confusion with a class variable, but with a twist...

    - by Omega
    I have a class called MyPackage.WebServer and it has a property called DBEngine. I am also dynamically loading a module and class using load_module. Inside this class, it attempts to reference MyPackage.WebServer. When it does though, DBEngine is not set to the value given when WebServer is instantiated. It's the default (None). Would the fact that I'm using load_module cause a different object graph to be created and thus isolate my dynamically loaded class from the rest of my python app?

  • Mock Objects properties not changing

    - by frictionlesspulley
    I am new to using Mock test in .Net. I am testing out a financial transaction which is of the following nature: int amt =20; //sets all the props and func and returns a FinaceAccount. //Note I did not SetUp the amt of the account. var account =GetFinanceAccount() //service layer to be tested _financeService.tranx(account,amt); //checks if the amt was added to the account.amt //here the amt comes out same as that set in GetFinanceAccount. Assert.AreEqual(account.amt ,amt) I know that the function tranx works correctly but there is an issue with the test. Are there any GOOD reference material on Mocking in .Net

  • Volatile keyword

    - by Tiyoal
    Say I have two threads and an object. One thread assigns the object: public void assign(MyObject o) { myObject = o; } Another thread uses the object: public void use() { myObject.use(); } Does the variable myObject have to be declared as volatile? I am trying to understand when to use volatile and when not, and this is puzzling me. Is it possible that the second thread keeps a reference to an old object in its local memory cache? If not, why not? Thanks a lot.

  • finditem() doesn't find menu, stuck with NullPointerException

    - by fdansv
    I'm stuck while changing some properties on my options menu at onCreateOptionsMenu(). It seems like findItem() returns null, even though I'm pretty sure that the reference to the menu item is correct. My code looks as follows: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_profile, menu); MenuItem leftie = menu.findItem(R.id.menu_profile); leftie.setIcon(R.drawable.ic_menu_mapmode); leftie.setTitle(R.string.back_map); leftie.setIntent(authIntent); return true; } I really don't know what can be wrong there. Thanks in advance :) EDIT: I forgot to include the actual problem.

  • Windows XP batch file concat

    - by dls
    I'm trying to accomplish the following ridiculous task: I have a text file containing a set of fully qualified filesnames. I want to iterate through the file and append each line to a common variable, that can be passed to a command line tool. For example, the file might be: C:\dir\test.txt C:\WINDOWS\test2.txt C:\text3.txt and I'd like to assign them to some variable 'a' such that: a = "C:\dir\test.txt C:\WINDOWS\test2.txt C:\text2.txt" A secondary question is - what is a good batch file reference? I'm finding some stuff in the Windows material, and a lot of home-grown websites, but nothing particularly complete. Thanks!

  • In Spring MVC, is it possible to have different return types in one request handler method?

    - by Bobo
    For example, if a request succeeds, I will return a View ,if not, return a String indicating error message and set the content-type to either xml or json. Based on what I read, seems like I should use "void" as the return type for handler methods. Check this out: "void if the method handles the response itself (by writing the response content directly, declaring an argument of type ServletResponse / HttpServletResponse for that purpose) or if the view name is supposed to be implicitly determined through a RequestToViewNameTranslator (not declaring a response argument in the handler method signature)."(Spring Framework reference). What I dont understand is what " the view name is supposed to be implicitly determined through a RequestToViewNameTranslator (not declaring a response argument in the handler method signature)" means? Any anyone give me an example?

  • Why don't hardware failures show up at the programming language level?

    - by Julian Cienfuegos
    I am wondering if anyone can give my a good answer, or at least point me in the direction of a good reference to the following question: How come I have never heard of a computer breaking in a very fundamental way? How come when I declare x to be a double it stays as a double? How come there is never a short circuit that robs it of some bytes and makes it an integer? Why do we have faith that when we initialize x to 10, there will never be a power surge that will cause it to become 11, or something similar? I think I need a better understanding of memory. Thanks, and please don't bash me over the head for such a simple/abstract question.

  • How do I make TODO comments show up in the task list for C++ projects in Visual Studio 2010?

    - by Chris Simmons
    I'm trying to get my TODO comments to show up in the task list in Visual Studio 2010 for a C++ project, but they don't. I looked at this, but see no caveats other than the TODO comments need to be in the currently-open file. For example, creating a new Win32 console app places this: // TODO: reference additional headers your program requires here in a new file, stdafx.h. However, there's nothing in the task list. I have "Comments" chosen from the drop-down in the task list, but it's always empty. And it's not this problem; I can open the file and be looking at the TODO comment in the code editor and no task is shown. This is not a problem for C# projects as TODO comments show up as designed in those projects; this appears to be an issue specific to C++ projects. What else can I check?

  • Best way to access nested data structures?

    - by Blackshark
    I would like to know what the best way (performance wise) to access a large data structure is. There are about hundred ways to do it but what is the most accessible for the compiler to optimize? One can access a value by foo[someindex].bar[indexlist[i].subelement[j]].baz[0] or create some pointer aliases like sometype_t* tmpfoo = &foo[someindex]; tmpfoo->bar[indexlist[i].subelement[j]].baz[0] or create reference aliases like sometype_t &tmpfoo = foo[someindex]; tmpfoo.bar[indexlist[i].subelement[j]].baz[0] and so forth...

  • C++ - How to call a member function for an inherited object.

    - by Francisco P.
    Hello! I have a few classes (heat, gas, contact, pressure) inheriting from a main one (sensor). I have a need to store them in a vector<Sensor *> (part of the specification). At some point in time, I need to call a function that indiscriminately stores those Sensor *. (also part of the specification, not open for discussion) Something like this: for(size_t i = 0; i < Sensors.size(); ++i) Sensors[i]->storeSensor(os) //os is an ofstream kind of object, passed onwards by reference Where and how shall storeSensor be defined? Is there any simple way to do this or will I need to disregard the specification? Mind you, I'm a beginner! Thanks for your time!
