• ASP MVC Set RadioButton From Database

  - by Jacob Huggart

  Hello All, I have what should be an easy question for you today. I have two radio buttons in my view: Sex: <%=Html.RadioButton("Sex", "Male", true)% Male <%=Html.RadioButton("Sex", "Female", true)% Female I need to select one based on the value returned from my database. The way I am trying to do it now is: ViewData["Sex"] = data.Sex; //Set radio button But that is not working. I have tried every possible combination of isChecked properties. I know that data.Sex is returning either "Male" or "Female". What do I need to do to check the appropriate radio button?

• Set environment variable for build in hudson

  - by pbreault

  I am trying to put a maven2 project under continuous integration in hudson. The project uses selenium for some integration testing. Hudson is running on a headless linux. I am using xvfb to start a x server session for selenium. In order to run the tests, I need to export an environment variable named DISPLAY. e.g. export DISPLAY=:99 However, I don't want to set the variable on the box since it would affect all builds. I have tried to do a shell execute using the m2 extra steps plugin but it doesnt work since it is executed in a separate bash file, meaning that environment variables are not persisted. Is there a way to register the environment variable from hudson.

• Using STL/Boost to initialize a hard-coded set<vector<int> >

  - by Hooked

  Like this question already asked, I'd like to initialize a container using STL where the elements are hard-coded in the cleanest manner possible. In this case, the elements are a doubly nested container: set<vector<int> > A; And I'd like (for example) to put the following values in: A = [[0,0,1],[0,1,0],[1,0,0],[0,0,0]]; C++0x fine, using g++ 4.4.1. STL is preferable as I don't use Boost for any other parts of the code (though I wouldn't mind an example with it!).

• given two bits in a set of four, fine position of two other bits

  - by aaa

  hello I am working on a simple combinatorics part, and found that I need to recover position of two bits given position of other two bits in 4-bits srring. for example, (0,1) maps to (2,3), (0,2) to (1,3), etc. for a total of six combinations. My solution is to test bits using four nested ternary operators: ab is a four bit string, with two bits set. c = ((((ab & 1) ? (((ab & 2) ? ... ))) : 0) abc = ab | c recover the last bit in the same fashion from abc. can you think of a better way/more clever way? thanks

• How can I set partial text color in JTextArea

  - by ComputerJy

  I want to set color for specific lines in the text area. What I've found so far, was the following // Declarations private final DefaultStyledDocument document; private final MutableAttributeSet homeAttributeSet; private final MutableAttributeSet awayAttributeSet; // Usage in the form constructor jTextAreaLog.setDocument(document); homeAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(homeAttributeSet, Color.blue); StyleConstants.setItalic(homeAttributeSet, true); awayAttributeSet = new SimpleAttributeSet(); StyleConstants.setForeground(awayAttributeSet, Color.red); // Setting the style of the last line final int start = jTextAreaLog.getLineStartOffset(jTextAreaLog.getLineCount() - 2); final int length = jTextAreaLog.getLineEndOffset(jTextAreaLog.getLineCount() - 1) - start; document.setCharacterAttributes(start, length, awayAttributeSet, true); But this is not working. What am I doing wrong?

• Open a new browser window, or set focus to an existing browser

  - by Craig Myles

  Hi, I'm using code similar to the following: http://blog.flexexamples.com/2007/08/29/launching-new-browser-windows-from-flex/ I have a Flex app running in AIR, and when I click on a URL it opens a new tab in my existing browser. In addition to this the focus doesn't set to the browser. What this means is that I'm not aware of the URL opening in the browser unless I actually change focus from the app to the browser. Is it possible to open a brand new spanking browser, or change focus to the browser so its really obvious to the user? Thanks.

• Spring: PropertyPlaceHolderConfigurer to set values for non-string/integer properties

  - by babyangel86

  Hi, All the examples I have seen where the PropertyPlaceHolderConfigurer is used seem to be setting simple values like Strings and ints. How do you use the PPC to set the values of classes. E.g. If i had a class signature Source(String name, DistributionSample batch, DistributionSample delay) How would I go about setting the batch and delay properties. There is also a small catch. DistributionSample is an abstract class. On the bright side, The class that is using the propertyPlaceHolder knows the beanName of the "Solid" class that needs to be instantiated. Any help would be much appreciated.

• how to souce a csh script in bash to set the enviroment

  - by Daniel

  We have oracle running on Solaris, and the shell is by default CSH. So the login script set the oracle_home,oracle_sid in csh also. But I don't like csh and want to use bash to do my work. So how to source the csh login script in bash? e.g, the following is what in the .cshrc file. And when use bash, I'd like use these variables. One way is to copy the variables again and use bash command, such as export ORACLE_SID=TEST. But doing so will let us to maintain two copy of the files. And when we change the database name, or upgrade the database, I need to maintian the bash login file seperately. It's nice to just use something like source .cshr in bash, but it doesn't work. setenv ORACLE_SID TEST setenv ORACLE_HOME /oracle/TEST/home/products/10204 setenv EPC_DISABLED TRUE setenv MANPATH /usr/local/man:/usr/share/man setenv EDITOR vi setenv LD_LIBRARY_PATH $ORACLE_HOME/lib:/usr/sfw/lib/64 setenv NLS_LANG AMERICAN_AMERICA.UTF8 setenv NLS_DATE_FORMAT "DD-MON-RR"

  I'm struggling to set connect a Java program to MySQL using JPA/Hibernate.

• PHP preg_replace function returns different values with the same data set

  - by patryk

  I need to use preg_match PHP function. I have a simple pattern to check the string and the thing is as follows: when I run the script at first, it gives me no match (it is supposed to match though) but when I hold F5 in my browser for a while, out of a sudden it says there's a match within the string. As I keep pushing F5, it gives either true or false. Say the pattern is /^(.*)\/[A-Za-z0-9]*$/ (I guess it's not the best way but still) and the subject is galeria/zdjecia/. I believe preg_match should return true with this set of data. Note that the data does not change when pressing F5. Why is that?

• Flash receives mouse events under an HTML element when opacity set

  - by Török Gábor

  I have an HTML document with a Flash object and an absolutely positioned HTML element above it. If I set the HTML element's opacity CSS property to any value less than 1, the Flash object (that is actually covered) receives mouse events. This problem cannot be reproduced with pure HTML elements. Furthermore, Flash only receives hover events, so I cannot click below the layer. I put a demonstration of the problem online. I get this behavior in Firefox 3.6, Safari 4.0 and Chrome 5.0 in both Mac and Windows. Flash plugin version 10 is installed. Is it a bug or the the normal and expected behavior? If the latter, then how can I prevent Flash receiving events when it is covered with a translucent layer?

• How to reserve a set of primary key identifiers for preloading bootstrap data

  - by Joshua

  We would like to reserve a set of primary key identifiers for all tables (e.g. 1-1000) so that we can bootstrap the system with pre-loaded system data. All our JPA entity classes have the following definition for the primary key. @Id @GeneratedValue(strategy = IDENTITY) @Column(name = "id", unique = true, nullable = false, insertable = false, updatable = false) private Integer id; is there a way to tell the database that increments should start happening from 1000 (i.e. customer specific data will start from 1000 onwards). We support (h2, mysql, postgres) in our environment and I would prefer a solution which can be driven via JPA and reverse engineering DDL tools from Hibernate. Let me know if this is the correct approach

• How do I set a matplotlib colorbar extents?

  - by Adam Fraser

  I'd like to display a colorbar representing an image's raw values along side a matplotlib imshow subplot which displays that image, normalized. I've been able to draw the image and a colorbar successfully like this, but the colorbar min and max values represent the normalized (0,1) image instead of the raw (0,99) image. f = plt.figure() # create toy image im = np.ones((100,100)) for x in range(100): im[x] = x # create imshow subplot ax = f.add_subplot(111) result = ax.imshow(im / im.max()) # Create the colorbar axc, kw = matplotlib.colorbar.make_axes(ax) cb = matplotlib.colorbar.Colorbar(axc, result) # Set the colorbar result.colorbar = cb If someone has a better mastery of the colorbar API, I'd love to hear from you. Thanks! Adam

• wxruby - Set max length of ComboBox

  - by Jonas Söderström

  Is is possible to set the Max length of a ComboBox in wxruby? I have looked in the documentation but find nothing http://wxruby.rubyforge.org/doc/combobox.html But if i do my_combobox.methods.sort I get set_max_size and set_min_size in the list. But When I call it my_combobox.set_max_length(100) I only get undefined method 'set_max_length' for #<Wx::ComboBox:0x4d4a914> I've also tried to call it as a private method def my_combobox.max(i) set_max_length(i) end my_combobox.max(100) But with the same result. The issue I want to avoid is that if somebody pastes 6000+ characters in my Combobox the text becomes white.

• Can't set a cookie in Chrome 5

  - by Nicolas

  Hi, Since today I am facing a tricky issue with Google Chrome that I've just updated to v5. I have a user login process running on my website. Everything works fine on FF 3.6.x and IE 7, but I just can't set any cookie in Google Chrome 5. I'm mentioning 5 because it worked very well before on v4. My PHP script looks like that: $cook = setcookie($cookieName, $value, $expires, '/', '.'.$domain); var_dump($cook, isset($_COOKIE[$cookieName])); I even tried the alternative setrawcookie without any result. $cook = setrawcookie($cookieName, $value, $expires, '/', '.'.$domain); var_dump($cook, isset($_COOKIE[$cookieName])); FF 3.6.x and IE7 output: bool(true) bool(true) Whereas Chrome v5 outputs: bool(true) bool(false) And obviously I see not trace of this cookie in Google Chrome 5. Any idea? =/ Cheers, Nicolas.

• How to keep the highlight border of a JComponent, when custom border is set

  - by Frederik Wordenskjold

  I have a JTextField, where I've set some custom properties: nameField.setPreferredSize(new Dimension(275,40)); nameField.setBackground(bgColor); nameField.setForeground(txtColor); nameField.setFont(new Font("HelveticaNeue",Font.PLAIN,22)); nameField.setBorder(BorderFactory.createLineBorder(Color.WHITE, 2)); When the component has focus, there is no highlight shown around the field. On a Mac, it is usually a blue glowing rectangle, indicating that this component has focus. If I comment out the nameField.setBorder(...), the highlight reappears. How do I keep the highlight, but also my custom border!? Basically, I just want the highlight-border to show when the component has focus, and no border when the component is unfocused.

• Jface's CheckboxTreeViewer how to set initial selection

  - by Hypercube

  Hello. This question may sounds trivial, but i am struggling with the issue, so, please help if u can. So, here it is : i am using a CheckboxTreeViewer for some good reasons. I've google-it for some class usages, and i am currently able to check/uncheck all the childrens of a selected node, and to preserve the selection after a live search with a custom implementation of the StyledCellLabelProvider provider. All good so far. However, so far i am unable to programatically select one or more elements of the tree viewer after i display the widget and call the setInput() method of the viewer. So, let's assume for instance that the tree will have 10 main nodes, and 5 leafs on node 6. My question is how do i set the checked state of the 3rd leaf? Thank u.

• fast algorithm implementation to sort very small set

  - by aaa

  hello. This is the problem I ran into long time ago. I thought I may ask your for your ideas. assume I have very small set of numbers (integers), 4 or 8 elements, that need to be sorted, fast. what would be the best approach/algorithm? my approach was to use the max/min functions. I guess my question pertains more to implementation, rather than type of algorithm. At this point it becomes somewhat hardware dependent , so let us assume Intel 64-bit processor with SSE3 . Thanks

• Set an Interface Builder created element's state programatically

  - by mvexel

  I have a couple of UISwitch elements in a view controller that is presented modally in my iPhone app. I set up the view in IB. I want these UISwitch elements to reflect the current values in my [NSUserDefaults standardUserDefaults] where I store the appropriate BOOLs. I thought this would do the trick setting the switches to the right state, but no: -(void)viewWillAppear:(BOOL)animated { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; [backgroundSwitch setOn:[defaults boolForKey:kTrackInBackgroundKey] animated:NO]; [batterySaveSwitch setOn:[defaults boolForKey:kBatterySaveKey] animated:NO]; } The backgroundSwitch and batterySaveSwitch are declared as properties for the view controller class. They are not initialized; that does not seem to make a difference. I did check the values coming out of the NSUserDefaults dictionary. The method is being called at the right time.
