  • Ensure Oracle row represents a unique timespan

    - by Dan F.
    I have to make a process in Oracle/PLSQL. I have to verify that the interval of time between start_date and end_date from a new row that I create must not intersect other start_dates and end_dates from other rows. Now I need to check each row for that condition and if it doesn't correspond the repetitive instruction should stop and after that to display a message such as "The interval of time given is not correct". I don't know how to make repetitive instructions in Oracle/PLSQL and I would appreciate if you would help me.

  • Building mono on Linux

    - by morpheous
    I have downloaded and built the latest version of mono (2.6.3), on Linux box (9.10). I have successfully built the C# compiler mcs, but it seems that the vb compiler vbnc was not built. Are there any special instructions required to build vbnc (other than configure, make, make install)? Has anyone managed to successfully build vbnc? - if yes, what do I need to do to build the vbnc executable?

  • Help installing delayed_job

    - by Mike
    I'm trying to use collectiveidea's delayed_job gem The installation instructions include Rake tasks are not automatically loaded from gems, so you’ll need to add the following to your Rakefile: begin require 'delayed/tasks' rescue LoadError STDERR.puts "Run `rake gems:install` to install delayed_job" end Where is my Rakefile? And what is a Rakefile?

  • Batch file command PAUSE does not work

    - by Samaursa
    I am creating a simple batch file to assist in a few things, and I have some instructions that it prints out as well that I want the user to see before exit. Currently, the window closes very quickly. So I added PAUSE at the end of the file, but it does not want to work. I looked at other questions on SO and have checked to make sure the line endings are CRLF and that I have CRLF at the end of the file. Any suggestions?

  • Android Calendar API vs Calendar Provider API

    - by John Roberts
    I'm a little bit confused about the difference between the two. An example of the Calendar API is supposedly located here: http://samples.google-api-java-client.googlecode.com/hg/calendar-android-sample/instructions.html, but the author himself suggests using the Calendar Provider API, details about which are here: http://developer.android.com/guide/topics/providers/calendar-provider.html. Can someone explain to me the difference between the two, and which would be better for me to use for a simple calendar app?

    I want to create a hgrc file to set the username and password for all paths on some machine, e.g no matter in which directory I am in, hg clone some_path will always work without prompting for a username and a password (this is for an auto-deploy script). I followed the instructions and created a file: /etc/mercurial/hgrc.d/deploy.rc it's contents: [auth] default.prefix= http://myrepo default.username = myuname default.password = pwd But when I do hg clone some_path I get abort: error: Connection refused. What Am i doing wrong?

  • change elements' css immediately on scroll event

    - by jedierikb
    I want to change the background color of in-viewport elements (using overflow: scroll) So here was my first attempt: http://jsfiddle.net/2YeZG/ As you see, there is a brief flicker of the previous color before the new color is painted. Others have had similar problems. Following the HTML5 rocks instructions, I tried to introduce requestAnimationFrame to fix this problem to no avail: http://jsfiddle.net/RETbF/ What am I doing wrong here?

  • Wrapping a Delphi TFrame descendant as an ActiveX control

    - by Mmarquee
    I am trying to wrap up a TFrame descendant as an ActiveX control, but don't seem to be able to get the control to show up in the ActiveX Control wizard. Is this approach possible, and if so, are there any working examples that I can be pointed at. I have tried to follow the instructions here, but as I said the control show in the list of available controls. Thanks in advance.

  • How to install new modes in emacs 23 on OS X?

    - by estanford
    I just downloaded the Haskell and J modes off of SourceForge, and I'm having trouble figuring out how to make them interface with emacs 23. Google searches yield detailed instructions for emacs 22, but it looks like changes have been made that make it hard to figure out where I'm supposed to stick the binaries. The internal documentation seems to assume more experience with emacs internals than I currently have, and the problem has resisted solution for several days. Does anyone know how to get these modes up and running?

  • can i use hadoop cloudera without root access?

    - by in_the_cloud
    a bit of a binary question (okay, not excatly) - but was wondering if one is able to configure cloudera / hadoop to run at the nodes without root shell access to the node computers (although i can setup ssh passwordless login)? appears from their instructions that root access is needed, at yet i found a hadoop wiki which suggest root access might not be needed ? http://wiki.apache.org/nutch/NutchHadoopTutorial

  • Looking for downloadable demo of a .Net service accessed through a pure JavaScript client, without r

    - by blueberryfields
    I am told that the configuration below is possible, but have had significant difficulty in finding instructions on how to set it up. While I'm trying to muddle my way through this on my own, maybe stack-overflow knows of better sources for documentation: I am looking for a walkthrough, including a downloadable, working example, for setting up the following configuration: Server-side .net application (For .net 2.0 or higher), installed/deployed as a windows' service (that is, not served through IIS), and accessed by a client tool that is completely implemented in JavaScript.

  • Java MVC project - either I can't update the drawing, or I can't see it

    - by user1881164
    I've got a project based around the Model-View-Controller paradigm, and I've been having a lot of trouble with getting it to work properly. The program has 4 panels, which are supposed to allow me to modify an oval drawn on the screen in various ways. These seem to work fine, and after considerable trouble I was able to get them to display in the JFrame which holds the whole shebang. I've managed to get them to display by breaking away from the provided instructions, but when I do that, I can't seem to get the oval to update. However, if I follow the directions to the letter, I only ever see an empty frame. The project had pretty specific directions, which I followed up to a point, but some of the documentation was unclear. I think what I'm missing must be something simple, since nothing is jumping out at me as not making sense. I have to admit though that my Java experience is limited and my experience with GUI design/paradigms is even more so. Anyway, I've been searching the web and this site extensively trying to figure out what's wrong, but this is a somewhat specific example and honestly I just don't know enough about this to generalize any of the answers I've found online and figure out what's missing. I've been poring over this code for far too long now so I'm really hoping someone can help me out. public class Model { private Controller controller; private View view; private MvcFrame mvcFrame; private int radius = 44; private Color color = Color.BLUE; private boolean solid = true; //bunch of mutators and accessors for the above variables public Model() { controller = new Controller(this); view = new View(this); mvcFrame = new MvcFrame(this); } } Here's the model class. This seems to be fairly simple. I think my understanding of what's going on here is solid, and nothing seems to be wrong. Included mostly for context. public class Controller extends JPanel{ private Model model; public Controller(Model model) { this.model = model; setBorder(BorderFactory.createLineBorder(Color.GREEN)); setLayout(new GridLayout(4,1)); add(new RadiusPanel(model)); add(new ColorPanel(model)); add(new SolidPanel(model)); add(new TitlePanel(model)); } } This is the Controller class. As far as I can tell, the setBorder, setLayout, and series of adds do nothing here. I had them commented out, but this is the way that the instructions told me to do things, so either there's a mistake there or something about my setup is wrong. However, when I did it this way, I would get an empty window (JFrame) but none of the panels would show up in it. What I did to fix this is put those add functions in the mvcFrame class: public class MvcFrame extends JFrame { private Model model; public MvcFrame(Model model){ this.model = model; //setLayout(new GridLayout(4,1)); //add(new RadiusPanel(model)); //add(new ColorPanel(model)); //add(new SolidPanel(model)); //add(new TitlePanel(model)); //add(new View(model)); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setLocationRelativeTo(null); setSize(800,600); setVisible(true); } } So here's where things kind of started getting weird. The first block of commented out code is the same as what's in the Controller class. The reason I have it commented out is because that was just a lucky guess - it's not supposed to be like that according to the instructions. However, this did work for getting the panels to show up - but at that point I was still tearing my hair out trying to get the oval to display. The other commented line ( add(new View(model)); ) was a different attempt at making things work. In this case, I put those add functions in the View class (see commented out code below). This actually worked to display both the oval and the panels, but that method wouldn't allow me to update the oval. Also, though I just had the oval displaying, I can't seem to figure out what exactly made that happen, and I can't seem to make it come back. public class View extends JPanel{ private Model model; public View(Model model) { this.model = model; //setLayout(new GridLayout(4,1)); //add(new RadiusPanel(model)); //add(new ColorPanel(model)); //add(new SolidPanel(model)); //add(new TitlePanel(model)); repaint(); } @Override protected void paintComponent(Graphics g){ super.paintComponent(g); //center of view panel, in pixels: int xCenter = getWidth()/2; int yCenter = getHeight()/2; int radius = model.getRadius(); int xStart = xCenter - radius; int yStart = yCenter - radius; int xWidth = 2 * radius; int yHeight = 2 * radius; g.setColor(model.getColor()); g.clearRect(0, 0, getWidth(), getHeight()); if (model.isSolid()){ g.fillOval(xStart, yStart, xWidth, yHeight); } else { g.drawOval(xStart, yStart, xWidth, yHeight); } } } Kinda same idea as before - the commented out code is stuff I added to try to get things working, but is not based on the provided directions. In the case where that stuff was uncommented, I had the add(new View(model)); line from the mvcFrame line uncommented as well. The various panel classes (SolidPanel, ColorPanel, etc) simply extend a class called ControlPanel which extends JPanel. These all seem to work as expected, not having much issue with them. There is also a driver which launches the GUI. This also seems to work as expected. The main problem I'm having is that I can't get the oval to show up, and the one time I could make it show up, none of the options for changing it seemed to work. I feel like I'm close but I'm just at a loss for other things to try out at this point. Anyone who can help will have my sincerest gratitude.
