  • Get label height for fixed width

    - by Jonas
    Is there any way I can get the height of a label, if it hypothetically had a certain width? I've been trying with control.GetPreferredSize(size) like so: Dim wantedWidth as Integer = 100 dim ctrlSize as Size = label.GetPreferredSize(new Size(wantedWidth, 0)) because I thought that setting height = 0, would indicate a free height, but the height I get is way too small. I also tried to estimate the height of the label, using Graphics.MeasureString to calculate the equivalent area of the Label dim prefWidth as Integer = 100 dim estSize as SizeF = g.MeasureString(label.Text, label.Font) dim estHeight as Integer = (Integer)(estSize.Width * estSize.Height / prefWidth) but that yields the same result. Any ideas? I'm on .NET 2.0, unfortunately.

  • Jboss failover testing

    - by Sam
    Hi All, I have a peculiar situation here. I have installed JBoss 5.1.0 as a service in Wintel box. The service will restart itself if the JBoss instance fails. However I could not find a way to test this scenario. I killed the JVM that was running the JBoss, but it did not restart the service. I need to make the JBoss service end abnormally so that I can ensure it is restarts again. In a nutsehll, I need a way to make JBoss end abnormally. Please help.

  • How to hide the title bar while application is loading and show it when it finishes loading?

    - by Arci
    I have an application which uses a custom title bar. However, when my application launches, I noticed that the default title bar is shown for a brief period of time. My problem is I don't want to show the default title bar while my application is loading. How do I hide the title bar while my application is loading so that there will be no hint of it and then show it afterwards? So far, I tried the following solutions but none have worked: Hide the title bar in XML and then set the custom title bar in code. (Problem encountered: I received an error message saying: "You cannot combine custom titles with other title features".) In XML: <item name="android:windowNoTitle">true</item> In onCreate method: requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); //... some code goes here getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title_header); Set the size of the title bar in XML to 0. Then change it's size via code later. (Problem encountered: I don't know how to set the size of title bar in code. Is it possible? I tried getWindow().setAttributes() and getWindow().setLayout() but both of them didn't worked.)" In XML: <item name="android:windowTitleSize">30dp</item> Modify windowTitleBackgroundStyle and set a transparent drawable as background. (Problem encountered: The content of the title bar became invisible but a line below the title bar is still visible.) In XML: <!-- style used by windowTitleBackgroundStyle --> <item name="android:background">@drawable/transparent</item>

  • What is the best way to mock a 3rd party object in ruby?

    - by spinlock
    I'm writing a test app using the twitter gem and I'd like to write an integration test but I can't figure out how to mock the objects in the Twitter namespace. Here's the function that I want to test: def build_twitter(omniauth) Twitter.configure do |config| config.consumer_key = TWITTER_KEY config.consumer_secret = TWITTER_SECRET config.oauth_token = omniauth['credentials']['token'] config.oauth_token_secret = omniauth['credentials']['secret'] end client = Twitter::Client.new user = client.current_user self.name = user.name end and here's the rspec test that I'm trying to write: feature 'testing oauth' do before(:each) do @twitter = double("Twitter") @twitter.stub!(:configure).and_return true @client = double("Twitter::Client") @client.stub!(:current_user).and_return(@user) @user = double("Twitter::User") @user.stub!(:name).and_return("Tester") end scenario 'twitter' do visit root_path login_with_oauth page.should have_content("Pages#home") end end But, I'm getting this error: 1) testing oauth twitter Failure/Error: login_with_oauth Twitter::Error::Unauthorized: GET https://api.twitter.com/1/account/verify_credentials.json: 401: Invalid / expired Token # ./app/models/user.rb:40:in `build_twitter' # ./app/models/user.rb:16:in `build_authentication' # ./app/controllers/authentications_controller.rb:47:in `create' # ./spec/support/integration_spec_helper.rb:3:in `login_with_oauth' # ./spec/integration/twit_test.rb:16:in `block (2 levels) in <top (required)>' The mocks above are using rspec but I'm open to trying mocha too. Any help would be greatly appreciated.

  • how to get selected chracter position in JTextArea?

    - by Reddy
    Hi! Here is a challenging question! Let me first tell you my scenario how am i implementing a solution to a problem. I am reading a log file and displaying it on the JTextArea. Log file is cp037 character coded. I was reading each file as a byte stream or byte array from the log file & displaying it. Anyways, i managed to display the text properly in JTextArea by cp037 character coding. Now, User may select a set of characters in the JTextArea. All i want is the position of first character of the user's selected text, from a nearest special character '+'(its character code in cp037 is 4E), which is prior to the selected text. This character may occur at several places in the JTextArea. In simple sentence, i want the first character location(of user selected text) from nearset '+' which should be occuring prior to the user's selected text. PS: cp037 is a type of character encoding scheme which is created by IBM & used for IBM Mainframes. Please fell free to ask me if the question is not clear...:-

  • JButtons re-enable themselves after being disabled

    - by Anarchist
    I have an array of JButtons which form a keypad interface. After six numbers are entered I want to disable the keypad so that no further numbers can be entered by the user. I have written the code and the buttons do disable until the mouse hovers above any of them, then the buttons seem to re-enable themselves and run actionEvents added to them. The full code is available here. Possible things that I think are wrong. There is some sort of MouseListener which is ignoring when I set button.setEnabled(false); I haven't separated attributes from the buildGUI(); correctly, I only did this anyway so that the inner class could access them. Possibly something to do with the gridLayout as disabling the buttons seems to work for my services JPanel buttons.

  • Best way to test instance methods without running __init__

    - by KenFar
    I've got a simple class that gets most of its arguments via init, which also runs a variety of private methods that do most of the work. Output is available either through access to object variables or public methods. Here's the problem - I'd like my unittest framework to directly call the private methods called by init with different data - without going through init. What's the best way to do this? So far, I've been refactoring these classes so that init does less and data is passed in separately. This makes testing easy, but I think the usability of the class suffers a little. EDIT: Example solution based on Ignacio's answer: import types class C(object): def __init__(self, number): new_number = self._foo(number) self._bar(new_number) def _foo(self, number): return number * 2 def _bar(self, number): print number * 10 #--- normal execution - should print 160: ------- MyC = C(8) #--- testing execution - should print 80 -------- MyC = object.__new__(C) MyC._bar(8)

Currently I have a very basic file viewer working as follows : - in JOptionPane I browse for files, and set some variables to display (colors, line connecting etc) - previous windows loads a frame with drawn points Code : http://paste.pocoo.org/show/220066/ Now I'd like to throw it into one window, with JMenu for selecting files and changing display parameters. How to get started ? Should I rewrite everything to JDialog ?

  • Compilig + testing an Android library with the JDK?

    - by Jarle Hansen
    Hi all, I am creating a library for Android that others can include in their own project. So far I have been working on it as a normal Java project with JDK 1.6 setup as system library. This works just fine in Eclipse when I add the android.jar. The issue comes when I try to my build script. I am running Gradle and doing a normal compile and test build cycle. My thoughts were that it does not matter if I compile it with a normal JDK, since this is not a standalone application. The benefits by creating a normal Java project is that Gradle does support this much better. My project also does not contain any UI at all. However, the problem is that of course android.jar and the JDK contains lots of the same classes and I think that this is what messes up my build script. Everything crashes when running the tests (the tests are in the same project under src/test/java). My question is, how should I create this project that is meant to be included in Android projects as a third party library? Should I create it as an Android project in Eclipse even though I am only creating a library that does not use any of the UI features? Also, should the tests be in a separate project? Thanks for all responses!

  • How to find thousands of company names?

    - by schefdev
    How can I find or generate thousands of company names for testing and demo purposes? (Address, phone number, and related information would be nice too.) I've got a system I'm building which includes business contact information. Pretty common no doubt. My test/demo database currently has randomly generated individual's names loaded (thanks to a handy IRS spreadsheet I found). This has worked great for internal testing and review purposes, but it looks really odd when shown to prospective customers. I've tried various online public information sources (e.g. EDGAR, and county based property records searches), but these all require me to manually stitch together the results in blocks of 50 names or so at a time. I could do this, but was really hoping for a search service or data store out there that had this type of information readily searchable and retrievable in very large batches.

  • Inline text box labels with WPF

    - by Douglas
    I'm trying to reproduce the layout of some paper forms in a WPF application. Labels for text boxes are to be "inline" with the content of the text boxes, rather than "outside" like normal Windows forms. So, with an Xxxxxx label: +-----------------------------+ | Xxxxxx: some text written | | in the multiline input. | | | | another paragraph continues | | without indentation. | | | | | +-----------------------------+ The Xxxxxx cannot be editable, if the user selects all the content of the text box, the label must remain unselected, I need to be able to style the text colour/formatting of the label separately, when there is no text in the text box, but it has focus, the caret should flash just after the label, and I need the baselines of the text in the text box and the label to line up. One solution I tried was putting a textblock partially over the input, then using text indent to indent the editable text, though this caused problems with following paragraphs, since they were indented too. I'm not sure how to indent just the first paragraph. It required some fiddling to get the text to line up - a more reliable setup would be ideal. So, any suggestions on how to set this up? Thanks

  • Testing for validity

  • Most efficient way for testing links

    - by Burnzy
    I'm currently developping an app that is going through all the files on a server and checking every single hrefs to check wether they are valid or not. Using a WebClient or a HttpWebRequest/HttpWebResponse is kinda overkilling the process because it downloads the whole page each time, which is useless, I only need to check if the link do not return 404. What would be the most efficient way? Socket seems to be a good way of doing it, however I'm not quite sure how this works. Thanks for sharing your expertise!

  • testing controller action which returns RedirectToRouteResult

    - by csetzkorn
    Hi, I have an action in my controller: RedirectToRouteResult Create(UserDTO UserDTO) Which at some point decides with which HTML to respond after a post request by redirecting to an action: return ModelState.IsValid ? RedirectToAction("ThanksCreate") : RedirectToAction("Register"); In my unit tests I would like to get hold of the ‘views’ modelstate somehow like this: var modelState = result.ViewData.ModelState; Assert.IsFalse( modelState.IsValid ); where ‘result’ (ViewResult) is the result of the action ‘Create’ depending on the submitted DTO. My dilemma is that my action ‘returns’ a RedirectToRouteResult which I thought is quite nice but it might not be testable or is it? How could I get hold of the ModelState in my scenario? Thanks. Best wishes, Christian enter code here

  • Custom Brush - I want two gradients chaining them together.

    - by Logan
    I am making a bar chart and I want two separate gradients for each bar. First I want a gradient to go from top to bottom solid red to transparent red. I want to paint over the top of that a gradient that goes from right to left, black to opaque. So - In the bottom left we should have; Bottom left - Alpha 0 Bottom right - Alpha 0 Top left - Alpha 255 Colour Red Top Right - Alpha 255 Colour Black So in effect I want to take a solid colour, add a left to right gradient to black then take the output of that and add a top to bottom gradient to transparency. All this and I want it to be in a single brush, is this even possible?

  • What are you using for Web UI/layout design?

    - by brendan
    What are folks out there using for web/ui design? For the most part we use PowerPoint at my company. The UI folks will mock up a screen in PowerPoint and we (the development group) will take it from there. So, for a side gig of mine I decided to do some mock ups to show the client prior to dev and I'm quickly feeling that PowerPoint is not the right tool for this. What are you using for this type of stuff - some other software? pen/paper?

  • What are MVP and MVC and what is the difference?

    - by Wolfbyte
    When looking beyond the RAD (drag-drop and configure) way of building User Interfaces that many tools encourage you are likely to come across 2 design patterns called Model-View-Controller and Model-View-Presenter. My question has two parts to it: What issues do these patterns address? How are they similar? How are they different?

  • Delay KeyUp Action if User is Typing (C#)

    - by Kirk
    I have a function that is being called when the user is typing in a search box. I want to wait for the user to finish typing before I actually execute the function. I know how to easily accomplish this in JavaScript with timeouts, but how would I go about doing the same thing in C#? Also, how long should I wait before I assume the user is done typing? 100ms?

  • Win32 script environment for testing http redirects?

    - by Anders Lindahl
    The past few days I've been working with setting up an Apache server on Windows. The server is supposed to host several .htaccess files, each redirecting (or, in some cases, proxying) to different hosts. I want to create tests for these redirectons, and the solution I'm currently considering is a CGI script running on the same server, sending GET requests to it and verifying that it gets the correct redirection headers back. A scripting solution (vscript/jscript) seems worth exploring, but so far I've only managed to rule out Microsoft.XMLHTTP because it follows the redirect "behind the scenes". Are there any libraries or other solutions already present on a reasonably standard Windows Server that can do this kind of low-level HTTP work? If not, any other suggestions of simple environments to set up for verifying redirects?
