  • WPF Multiline TextBlock LineBreak issues

    - by KMC
    I have the following code txtBlock1.Inlines.Add("This is first paragraph \n This is second paragraph"); then TextBlock would display: This is first paragraph This is second paragraph But, if I have the following (which I though is equivalent); txtBlock1.Inlines.Add("This is first paragraph"); txtBlock1.Inlines.Add("\n"); txtBlock1.Inlines.Add("This is second paragraph"); TextBlock display: This is first paragraph // but second paragraph missing If I separate out the linebreak then the rest of text after the linebreak doesn't show. Why? I have to use run: Run run1 = new Run(); run1.Text = "First Paragraph"; run1.Text += "\n"; run1.Text += "Second Paragraph"; txtBlock1.Inlines.Add(run1); Then it produce the result correctly. Why I cannot add inline text to Textblock and require me to use Run?

  • Rails CSV import, adding to a related table

    - by Jack
    Hi, I have a csv importing system on my app (used locally only) which parses the csv file line by line and adds the data to the database table. This is based on a tutorial here. require 'csv' def csv_import @parsed_file=CSV::Reader.parse(params[:dump][:file]) n = 0 @parsed_file.each_with_index do |row, i| next if i == 0 #ignore the first row course = Course.new course.title = row[0] course.unit_code = row[1] course.course_type = row[2] course.value = row[3] course.pass_mark = row[4] if course.save n = n+1 GC.start if n%50==0 end flash.now[:message] = "CSV Import Successful, #{n} new courses added to the database." end redirect_to(courses_url) end This is all in the courses controller and works fine. There is a relationship that courses HABTM years and years HABTM courses. In the csv file (effectively in row[5] to row[8]) are the year_id s. Is there a way that I can add this within the method above. I am confused as to how to loop over the 4 items and add them to the courses_years table. Thank you Jack

  • How much user data should be required to grant a password reset?

    - by Andrew Heath
    I'm looking to add password-reset functionality to my site and have been browsing the numerous threads discussing various aspects of that issue here on SO. One thing I haven't really seen clarified is how much information to require from the user for confirmation before sending out the reset email. is email alone enough? email + account username? email + account username + some other identifying value all accounts must input? I don't want my site to seem like an old wrinkly nun with a ruler, but I don't want people to be able to abuse the password reset system willy-nilly. Suggestions?

  • Sending forgot password emails

    - by GeoffreyF67
    I am building a service that will have a 'forgot my password' feature. In addition to that, it will also email users when results are ready from my service. I would like to ensure delivery of my emails so I was looking around to find a service that would let me send emails. All that I've been able to find so far are services that require a user to opt-in to a list. In other words, I've been unable to find any that will let me send customized messages to individual users. I am currently using swiftmailer for php but would really like to find a service to do this...Anyone know of one? G-Man

  • Where can I find the gtk-builder-convert script?

    - by Marty
    I've built a small GUI app for work that uses some .glade files for pop-up windows. Recently, the ground beneath me was shifted - my environment was upgraded. Newer pyGTK versions require GTKBuilder and .xml files instead of Glade and .glade files and now my poor app is broken. I need to convert the .glade file to the newer .xml file. Problem is Glade-3 is not on our system, and I can't find gtk-builder-convert on the web. I've looked at the Gnome GIT Browser, don't know where to start looking or how to search it. Would anyone be kind enough to point me to the gtk-builder-convert python script?

  • TestCase scripting framework

    - by Mikey
    Hey guys, For our webapp testing environment we're currently using watin with a bunch of unit tests, and we're looking to move to selenium and use more frameworks. We're currently looking at Selenium2 + Gallio + Xunit.net, However one of the things we're really looking to get around is compiled testcases. Ideally we want testcases that can be edited in VS with intellisense, but don't require re-compilling the assembly every single time we make a small change, Are there any frameworks likely to help with this issue? Are there any nice UI tools to help manage massive ammount of testcases? Ideally we want the testcase writing process to be simple so that more testers can aid in writing them. cheers

  • Rails: simple bundler question

    - by Joern Akkermann
    Hi! I just installed the ruby-openid gem and then bundled it by entering gem 'ruby-openid', :require => 'openid' in the gemfile. Then I started bundle install and bundle lock. Everything worked fine so far. But how can I now access the classes of ruby-openid. OpenID::method won't work for me. It raises a not found error. What have I forgot or done wrong? I'm thankful for any help!

  • DataSetProvider - DataSet to ClientDataSet

    - by nomad311
    I am trying to take data from a TMSQuery which is connected to my DB and populate a ClientDataSet with some of that data using a DataSetProvider. My problem is that I will need to modify some of this data before it can go into my ClientDataSet. The ClientDataSet has persistent fields that will not match up with the raw DB data. I can't even get a string from the DB into a memo field in ClientDataSet. The ClientDataSet is a part of my data tier so I will need to conform the data from the DB to the ClientDataSet field by field (well most will be able to go right through, but many will require routing and/or conversion). Does anyone have experience with this?

  • help finding a hosing company with unixODBC and FreeTDS support

    - by patrick
    I need to find a hosting company that provides a LAMP stack, the P being PHP. Finding that is pretty easy, but I have a further requirement of unixODBC and FreeTDS or some equilant. The project will require a remote connection to a Microsoft SQL 2005 database. Most of the project will use a local MySQL database but it also requires data from a remote MS SQL 2005 database. In my reading it looks like I'll need unixODBC and FreeTDS installed on the server to make that connection. So far I've been unable to find a shared host that provides these. Can anyone suggest or use a host that might work? The project has budget limits so we we're hoping to find a shared host.

  • What is the difference between building a WSDL in Eclipse and using WCF?

    - by myermian
    I'm somewhat familiar with WCF in that I can build Web Services in VS.Net ... I understand some of the concepts... But, the other day I cam across this option in Eclipse (I also use Java to code) to create a WSDL. Playing around with it it looks great since it has a GUI method of building itself. I guess I just wanna know what the difference is. 1) Are they different technologies like WSDL vs WCF? Or, is it that WCF uses WSDLs? 2) I read that WSDLs are a top-down approach... so what about WCF, is that top-down or is that bottom-up? 3) Will this WSDL in Eclipse actually be able to generate CSharp code for my server and client efficiently, or will it require a lot of fixing?

  • How to use xcode compiler warnings to determine minimum IOS deployment target

    - by Martin Bayly
    I'm building an iOS app using Xcode 3.2.5 with the Base SDK set to iOS 4.2 I know I've used some api's from 4.0 and 4.1 but not sure about whether I actually require 4.2. According to the iOS Development Guide, "Xcode displays build warnings when it detects that your application is using a feature that’s not available in the target OS release". So I was hoping to use the compiler warnings to derive my minimum OS requirement. However, even when I set my iOS Deployment Target to iOS 3.0, I still don't get any compiler warnings. I must be doing something wrong, but not sure what? Can anyone confirm that they get compiler warnings when the iOS deployment target is less than the base SDK and the code uses base SDK functions? Or do the compiler warnings only show if you link a framework that didn't exist in the iOS deployment target version?

  • Why isn't Passenger respecting my custom log format?

    - by Millisami
    I need to change the log format of my rails app. I put this file in lib directory and required it in development.rb env file. require 'hodel_3000_compliant_logger' config.logger = Hodel3000CompliantLogger.new(config.log_path) and I should get the output of the development.log file as follows: Jun 28 03:05:13 millisami-notebook rails[18243]: Memory usage: 86888 | PID: 18243 I get this exact log when I start my app with script/server (Mongrel). But when I run the app via Passenger, the format being logged is Rails' default. Why doesn't Passenger write to the log file like Mongrel does?

  • Any way to separate unit tests from integration tests in VS2008?

    - by AngryHacker
    I have a project full of tests, unit and integration alike. Integration tests require that a pretty large database be present, so it's difficult to make it a part of the build process simply because of the time that it takes to re-initialize the database. Is there a way to somehow separate unit tests from integration tests and have the build server just run the unit tests? I see that there is an Ordered Unit test in VS2008, which allows you to pick and choose tests, but I can't make it just execute alone, without all the others. Is there a trick that I am missing? Or perhaps I could adorn the unit tests with an attribute? What are some of the approaches people are using? P.S. I know I could use mocking for integration tests (just to make them go faster) but then it wouldn't be a true integration test.

  • SQL Server - Storing multiple decimal values in a column?

    - by cshah
    I know storing multiple values in a column. Not a good idea. It violates first normal form --- which states NO multi valued attributes. Normalize period... I am using SQL Server 2005 I have a table that require to store lower limit and uppper limit for a measurement, think of it as a minimum and maximum speed limit... only problem is only 2 % out of hundread i need upper limit. I will only have data for lower limit. I was thinking to store both values in a column (Sparse column introduces in 2008 so not for me) Is there a way...? Not sure about XML..

  • Web Application Translation, methods and tools

    - by CiscoIPPhone
    I've developed a web application. It needs to be translated to languages other than English in the future, and ideally the translators shouldn't need to know HTML/JS/C++ to provide the translation. The server side of the web application is written in C++ and the majority of the localised text is in the HTML files. My question is: What approaches are there to translating web applications? - Are there any existing tools that would enable a translator who doesn't understand HTML to translate a site? Should I write an application that extracts the localised text from a html file and can re-substitute translated text? Do you just provide the html file to your translators to be localised? I'm aware the question isn't strictly programming related but the solution may involve programming and it may require some software engineering.

  • Application Server or Lightweight Container?

    - by Jeff Storey
    Let me preface this by saying this is not an actual situation of mine but I'm asking this question more for my own knowledge and to get other people's inputs here. I've used both Spring and EJB3/JBoss, and for the smaller types of applications I've built, Spring (+Tomcat when needed) has been much simpler to use. However, when scaling up to larger applications that require things like load balancing and clustering, is Spring still a viable solution? Or is it time to turn to a solution like EJB3/JBoss when you start to get big enough to need that? I'm not sure if I've scoped the problem well enough to get a good answer, so please let me know. Thanks, Jeff

  • Good programming style when handling multiple objects

    - by Glitch
    I've been programming a software version of a board game. Thus far I have written the classes which will correspond to physical objects on the game board. I'm well into writing the program logic, however I've found that many of the logic classes require access to the same objects. At first I was passing the appropriate objects to methods as they were called, but this was getting very tedious, particularly when the methods required many objects to perform their tasks. To solve this, I created a class which initialises and stores all the objects I need. This allows me to access an object from any class by calling Assets.dice(), for example. But now that I've thought about it, this doesn't seem right. This is why I'm here, I fear that I've created some sort of god class. Is this fear unfounded, or have I created a recipe for disaster?

  • Graph Generation in flex

    - by Roshan
    I need to generate a graph using the following XML in FLEX. [Bindable] public var stockDataAC:ArrayCollection = new ArrayCollection( [ {date: "2010, 4, 27", close: 41.71}, {date: "2010, 4, 28", close: 42.21}, {date: "2010, 5, 2", close: 42.71}, {date: "2010, 5, 3", close: 42.99}, {date: "2010, 5, 4", close: 44} ]); .............. < mx:horizontalAxis < mx:DateTimeAxis dataUnits="days" displayLocalTime="true" parseFunction="myParseFunction" / < /mx:horizontalAxis But this displays the graph from 2010/4/27 till 2010/5/4 including 2010/4/29, 2010/4/30 and 2010/5/1. I require the graph to display only the points in XML and exclude remaining thought it lies in between since it contains no data. How this can be done?

  • Defining Makefiles variables from a script

    - by Freddy
    I am creating a Makefile which I want it to be a single file for different architectures, OSes, libraries, etc. To do this I have a build specific XML file which defines the different configuration options for each architecture. The config file is read by Perl (it could be any language) and the Perl output returns something like: var1 := var1_value var2 := var2_value var3 := var3_value What I am trying to do is define this variables in my Makefile. From the makefile I am calling my readconfig script and it is giving the correct output, but I have not been able to get this variables as part of my Makefile. I have tried the use of eval and value, but none of them have work (although it could be an issue of me not knowing how to use them. In overall what I am trying to do is something like: read_config: $(eval (perl '-require "readConfig.pl"')) @echo $(var1) It could be assumed I am using only GNU Make behavior. Things I could not change: Config file is on XML Using Perl as a XML parser

  • How to easily pass a very long string to a worker process under Windows?

    - by sharptooth
    My native C++ Win32 program spawns a worker process and needs to pass a huge configuration string to it. Currently it just passes the string as a command line to CreateProcess(). The problem is the string is getting longer and now it doesn't fit into the 32K characters limitation imposed by Windows. Of course I could do something like complicating the worker process start - I use the RPC server in it anyway and I could introduce an RPC request for passing the configuration string, but this will require a lot of changes and make the solution not so reliable. Saving the data into a file for passing is also not very elegant - the file could be left on the filesystem and become garbage. What other simple ways are there for passing long strings to a worker process started by my program on Windows?

  • Lightweight web browser for testing

    - by Ghostrider
    I have e very specific test setup in mind. I would like to start a web-browser that understands Javascript and can use HTTP proxy, point it to a URL (ideally by specifying it in the command line along with the proxy config), wait for the page to load while listening (in the proxy) requests are generated as web-page is rendered and Javascript is executed, then kill the whole thing and restart. I don't care about how the page renders graphically at all. Which browser or tool should I use for this? Ideally it should be something self-contained that doesn't require installation (just an EXE file that runs from command line). Lynx would have been ideal but for the fact that it doesn't support JS. It should have as small memory footprint as possible.

  • How do I watch a file for changes using Python?

    - by Jon Cage
    I have a log file being written by another process which I want to watch for changes. Each time a change occurrs I'd like to read the new data in to do some processing on it. What's the best way to do this? I was hoping there'd be some sort of hook from the PyWin32 library. I've found the win32file.FindNextChangeNotification function but have no idea how to ask it to watch a specific file. If anyone's done anything like this I'd be really grateful to hear how... [Edit] I should have mentioned that I was after a solution that doesn't require polling. [Edit] Curses! It seems this doesn't work over a mapped network drive. I'm guessing windows doesn't 'hear' any updates to the file the way it does on a local disk.

  • Windows 7 sharing data between users via the registry

    - by r99
    Where can I create/modify/delete registry keys to share data between users in the Windows 7 registry? Both of the users are non administrators and it shouldn't require admin privileges. The application I'm working on uses the registry to write a key from userA and then userB can read/modify/delete it. Neither user has admin privileges and it won't be possible to change this. Is there an official MSDN guide to how to use the registry in Windows 7? Any links describing proper use of the registry would be useful.
