  • How do I echo $command without breaking the layout

    - by w00t
    Hi. I'm trying to do the following in a bash script: com=`ssh host "ls -lh" ` echo $com It works, but the echo will break the output (instead of getting all lines in a column, I get them all in a row). If I do: ssh host ls -lh in the CLI it will give me the correct output + layout. Any ideas?

  • MySQL create view from concat value

    - by cnotethegr8
    Lets say I have a table as follows, +----+-------------+ | id | value | +----+-------------+ | 1 | aa,bb,cc,dd | | 2 | ee,ff,gg,hh | +----+-------------+ I want to be able to search this table to see if id = 1 AND value = 'cc'. Im assuming a good way of doing this is to grab the id = 1 row and split its values into separate rows in a new view. Something like, +-----+ | val | +-----+ | aa | | bb | | cc | | dd | +-----+ I would like to do all of this in MySQL. How can i do this, and is there possibly a better way to do it?

    I am trying to recreate something like the following SQL using NHibernate criteria: select Range, count(*) from ( select case when ent.ID between 'A' and 'N' then 'A-M' else 'Other' end as Range from Subject ) tbl group by tbl.Range I am able to create the inner select as follows: session.CreateCriteria<Subject>() .SetProjection( Projections.Conditional( Expression.Between("Name", "A", "N"), Projections.Constant("A-M"), Projections.Constant("Other"))) .List(); However, I can't figure out how to pipe those results into a grouping by row count.

  • UITableViewCell outlets not set during bundle load (possibly very elementary question)

    - by Jan Zich
    What are the most common reasons for an outlet (a class property) not being set during a bundle load? I'm sorry; most likely I'm not using the correct terms. It's my first steps with iPhone OS development and Objective-C, so please bear with me. Here is more details. Basically, I'm trying to create a table view based form with a fixed number of static rows. I followed this example: http://developer.apple.com/iphone/library/documentation/userexperience/conceptual/TableView_iPhone/TableViewCells/TableViewCells.html Scroll down to The Technique for Static Row Content please. I have one nib file with one table view, three table cells and all connections set as in the example. The problem is that the corresponding cell properties in my controller are never initialised. I get an exception in cellForRowAtIndexPath complaining that the returned cell is nil: UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath. Here are the relevant parts from the implementation of the controller: @synthesize cellA; @synthesize cellB; @synthesize cellC; - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 3; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { switch (indexPath.row) { case 0: return cellA; break; case 1: return cellB; break; case 2: return cellC; break; default: return nil; } } And here is the interface part: @interface AssociatePhoneViewController : UITableViewController { UITableViewCell *cellA; UITableViewCell *cellB; UITableViewCell *cellB; } @property (nonatomic, retain) IBOutlet UITableViewCell *cellA; @property (nonatomic, retain) IBOutlet UITableViewCell *cellB; @property (nonatomic, retain) IBOutlet UITableViewCell *cellC; @end This must be possibly one of the the most embarrassing questions on StackOverflow. It looks like the most basic example code. Is is possible that the cells are not instantiated with the nib file? I have them on the same level before the tabula view in the nib file. I tried to move them after the table view, but it did not make any difference. Are table cells in some way special? Do I need to set some flag or some property on them in the nib file? I was under the impression that all classes (views, windows, controllers …) listed in a nib file are simply instantiated (and linked using the provided connections). Could it possibly be some memory issue? The cell properties in my controller are not defined in any special way.

  • most popular j2ee based websites

    - by krishna
    J2EE as I understand is used to build Enterprise applications. My question is :What are the most popular public facing(internet) sites using j2ee stack. The one's that I know of are : linkedIn.com ,evite.com and sun ibm and oracle (obviously) Eclipse.org uses php, I wonder why? If you have worked on/know any other sites, can your share your experience and also the technologies used(if that's not an issue)? EDIT:It doesn't have to use the full stack. EDIT : There are quite a few ecommerce websites like bestbuy.com. I know this bcos I worked with the ATG(atg.com) ecommerce suite and their website lists their clients. Iam looking for those kind of examples and also your experience working on them. Please limit to only internet sites

  • Casting a primitive int to a Number

    - by Tamer
    Let's say that I have the following: int a = 2; Number b = (Number) a; System.out.println(b); // Prints 2 http://java.sun.com/docs/books/jls/first_edition/html/15.doc.html#238146 says that a primitive value may not be cast to a reference type. Does Java know to create an Integer from the primitive int and then cast to the superclass? How exactly does Java handle this behind the scenes? Thanks!

  • Is there any .Net JIT Support from chip vendors?

    - by NoMoreZealots
    I know that ARM actually has some support for Java and SUN obviously, but I haven't really references seen any chip vendor supporting a .Net JIT compiler. I know IBM and Intel both support C compilers, as well as TI and many of the embedded chip vendors. When you think of it, all a JIT compiler is, is the last stages of compilation and optimization which you would think would be a good match for a chip vendor's expertize. Perhaps a standardized Plug In compilation engine for the VM would make sense. Microsoft is targeting .Net to embedded Windows platforms as well, so they are fair game. Pete

  • WPF Inner Property Binding not updating.

    - by Matthew Kruskamp
    I have an INotifyProperty item that I have bound to a wpf control. <local:ScrollingSelector DataContext="{Binding Path=SelectedScreen.VisualizationTypes}" Grid.ColumnSpan="2" Grid.Column="3" Margin="0,0,0,0" Grid.Row="1"/> If I change the SelectedScreen property to a different control the binding still assumes the first control. Why is this? Is there an easy work-around?

  • jquery delegate table rows selector

    - by Jackob
    I have a table which may contains other inner tables (it's not possible to edit generated markup). I want to create a delegate function for row mouseenter and mouseleave which only triggers for the associated main table rows (and not inner tables rows), as following: $("#tableid").delegate("tr", "mouseenter mouseleave", function(e) { //do stuff here }); But with this selector it selects also the inner table rows, so how can I modify the selector to avoid selecting inner table rows?

  • Dojo and Ajax - rendering widgets

    - by Michael Merchant
    I'm trying to load content into a Dojo content pane in a specific html tag and not replace the entire content pane. The html I'm loading includes a markup defined widget that I'd like to have rendered when the new row is loaded. So, I have a table that is being dynamically filled via ajax,ie: <body> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/dojo/1.5/dojo/dojo.xd.js" djConfig="parseOnLoad: true, isDebug:true"></script> <div id="table-pane" dojoType="dijit.layout.ContentPane"> <table class="test"> <tbody> <tr><td>Name</td><td>Year</td><td>Age</td></tr> <tr> <td><span dojoType="dijit.InlineEditBox" editor="dijit.form.Textarea">Mike</span> </td> <td>2010</td> <td>12</td> </tr> </tbody> </table> </div> </body> <script> var html ='<tr><td><span dojoType="dijit.InlineEditBox" editor="dijit.form.Textarea">John</span></td><td>2011</td><td>22</td></tr>'; dojo.require("dijit.layout.ContentPane"); dojo.require("dijit.InlineEditBox"); dojo.require("dijit.form.Textarea"); dojo.addOnLoad(function(){ pane = dijit.byId("table-pane"); add_elem(); }); function add_elem(){ var node = $(".test tr:last"); node.after(html); dojo.addOnLoad(function(){ //Here I want to initiate any widgets that haven't been initiated pane.buildRendering(); }); }</script> How do I render the Dojo widget in the new table row?

  • Wicket app in embedded Jetty causes UnsupportedClassVersionError

    - by Ondra Žižka
    I've tried to run a Wicket app in an embedded Jetty, using this code: public static void main( String[] args ){ Server server = new Server(8080); Context root = new Context( server, "/", Context.SESSIONS ); FilterHolder filterHolder = new FilterHolder( new WicketFilter() ); filterHolder.getInitParameters().put("applicationClassName", cz.dw.test.WicketApplication.class.getName() ); root.addFilter( filterHolder, "/*" , Handler.ALL ); try { server.start(); } catch (Exception ex) { ex.printStackTrace(); } } But I got java.lang.UnsupportedClassVersionError: Bad version number in .class file. Switching the target class version for my app (1.6 - 1.5) did not help. I use Sun JDK 1.6.0_17, Wicket 1.4.8, Jetty 6.1.24. I tried to debug, but the JRE classes have no debug data. The stacktrace is of no use as it happens when loading the classes into JVM. Any ideas what could be wrong? How can I find which class is causing this? Thanks, Ondra

  • Delete last line in txt file

    - by user3658127
    I wrote a foreach loop for my datagridview to write all rows to txt file. I have a problem as it adds 2 empty lines at the end, as 1 row is full of empty cells after adding/reading to datagrid view. Is there any way to omit the last line or delete it in txt? foreach (DataGridViewRow item in this.DB.Rows) { foreach (DataGridViewCell item2 in item.Cells) { if(item2.Value != null) filewrite.Write(item2.Value.ToString() + " "); } filewrite.WriteLine(""); }

  • Why is NavigationHandler.handleNavigation() not forwarding to view ID?

    - by Erik Hermansen
    Inside of a phase listener class that runs during the "RESTORE_VIEW" phase, I have some code like this: public void afterPhase(PhaseEvent event) { FacesContext fc = event.getFacesContext(); NavigationHandler nh = fc.getApplication().getNavigationHandler(); nh.handleNavigation(fc, null, "/a/specific/path/to/a/resource.jspx"); } Navigation to the new URL doesn't work here. The request made will just receive a response from the original JSPX that was navigated to. Code like this works fine: public void afterPhase(PhaseEvent event) { FacesContext fc = event.getFacesContext(); NavigationHandler nh = fc.getApplication().getNavigationHandler(); nh.handleNavigation(fc, null, "OUTCOME_DEFINED_IN_FACES_CONFIG_XML"); } Also the first snippet will work with an IceFaces Faces provider, but not Sun JSF 1.2 which is what I need to use. Is there something I can do to fix the code so it is possible to forward to specific URLs?

    - by theactiveactor
    In Django admin site, when listing all the objects for a given model, I know we can customize which columns get displayed for a ModelA via list_display Say that ModelA has a one-to-many relationship with ModelB. I would like to add another column on the listing page for ModelA, where each entry is a URL pointing to all objects of ModelB having a foreign key relationship on corresponding instance of Model A in that row. How can I achieve this customization with the admin app?

  • Using C# with Crystal Reports, How Can I Create 4-Up Subreports?

    - by C. Griffin
    The simplest example that I can provide for what I want to do is this: I need to create a Report, whose only requirement is that I have (4) of the same subreport on the page (imagine 4 portrait-oriented post cards on a page), each quadrant using a separate row from my datatable, yet all 4 are identical in terms of fields. If there are more than 4, it needs to carry over to a new page with the same format. I'm using C# and the built-in Crystal Reports Basic for the task.

  • Matching 'weird' characters in PHP regex

    - by Bill X
    I have some strings that need a-strippin': ÜT: 9.996636,76.294363 Tons of long strings of location codes. A literal regex in PHP won't match them, IE $pattern = /ÜT:/; echo preg_replace($pattern, "", $row['location']); Won't match/strip anything. (To know it's working, /T:/ does strip the last bit of that string). What's the encoding error doing on here? Alternately, I would accept a concise way to take out just the numbers.
