  • Booting From VIA VT6421A Based PCI SATA Card

    - by Priyan R
    I bought a VIA VT6421A based SATA card for an 845 chipset based motherboard. The card is working i can access sata hdd from windows/linux. The problem is i can't directly boot from the sata card. My motherboard is award bios 6 based. I tried first boot as SCSI, its not worked. There is no Raid Bios screen appeared from the card. On searching i found , Add VT6421A bios to system bios as pci addon bios. I did it using cbrom6 , successfully added VT6421A bios to the existing bios. But now on booting instead of raid bios system bios showed Warning : something like cannot load add on rom for vendor id xxxx device id xxx . Whats wrong ? As the card is VT6421A based and i added VT6421A bios got from VIA website.

  • Invoke Java via Batch File with Filepath Arguments

    - by EricIdyll
    Hi there, I'm having an issue getting files loaded into an app called GCS, by dragging them onto the executable. GCS can be invoked on Windows with a bat file, which goes like this: @echo off start javaw -Xmx256M -jar "GURPS Character Sheet.app/Contents/Resources/Java/GCS.jar" %* If I hard code a filepath in place of the batch argument wildcard (with quotes), it works. If I run the debugger with a filepath argument it works. If I echo %, it gives me the correct filename with quotes around it. If I add quotes around % it still breaks. I have a disconnect here between DOS and Java, and I'm at a loss. Does anyone recognize this problem? Thanks in advance.

  • Scrum burn down charts, can they go negative?

    - by AaronThomson
    I work on a small Agile development team which is part of a large, non-agile thinking corporation. Currently, we practise Scrum and occasionally, we exceed our sprint commitment. My question is, how do you handle burn down charts when you have exceeded your sprint commitment? I can think of two options: Extend the y-axis in the negative direction and keep counting down Add more cards/stories/work and have the burn down value increase by that amount, burning down when that work is finished. The ultimate solution for my team is one which is clear to the business and adds real value for the developers. So far, neither of these solutions has worked out perfectly.

  • JList - deselect when clicking an already selected item

    - by Peter
    If a selected index on a JList is clicked, I want it to de-select. In other words, clicking on the indices actually toggles their selection. Didn't look like this was supported, so I tried list.addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent evt) { java.awt.Point point = evt.getPoint(); int index = list.locationToIndex(point); if (list.isSelectedIndex(index)) list.removeSelectionInterval(index, index); } }); The problem here is that this is being invoked after JList has already acted on the mouse event, so it deselects everything. So then I tried removing all of JList's MouseListeners, adding my own, and then adding all of the default listeners back. That didn't work, since JList would reselect the index after I had deselected it. Anyway, what I eventually came up with is MouseListener[] mls = list.getMouseListeners(); for (MouseListener ml : mls) list.removeMouseListener(ml); list.addMouseListener(new MouseAdapter() { public void mousePressed(MouseEvent evt) { java.awt.Point point = evt.getPoint(); final int index = list.locationToIndex(point); if (list.isSelectedIndex(index)) SwingUtilities.invokeLater(new Runnable() { public void run() { list.removeSelectionInterval(index, index); } }); } }); for (MouseListener ml : mls) list.addMouseListener(ml); ... and that works. But I don't like it. Is there a better way?

  • Configuring TeamCity + NUnit unit tests so files can be loaded properly

    - by Dave
    In a nutshell, I have a solution that builds fine in the IDE, and the unit tests all run fine with the NUnit GUI (via the NUnitit VS2008 plugin). However, when I execute my TeamCity build runner, all unit tests that require file access (e.g. for running tests against specific XML files), I just get System.IO.DirectoryNotFoundExceptions. The reason for this is clear: it's looking for those supporting XML files loaded by various unit tests in the wrong folder. The way my unit tests are structured looks like this: +-- project folder +-- unit tests folder +-- test.xml +-- test.cs +-- project file.xaml +-- project file.xaml.cs All of my projects own their own UnitTests folder, which contains the .cs file and any XML files, XML Schemas, etc that are necessary to run the tests. So when I write my test.cs, I have it look for "test.xml" in the code because they are in the same folder (actually, I do something like ....\unit tests\test.xml, but that's kind of silly). As I said before, the tests run great in NUnit. But that's because the unit tests are part of the project. When running the unit tests from TeamCity, I am executing them against the assemblies that get copied to the main app's output folder. These unit test XML files should not be copied willy-nilly to the output folder just to make the tests pass. Can anyone suggest a better method of organizing my unit tests in each project (which are dependencies for the main app), such that I can execute the unit tests from NUnit and from the TeamCity build runner? The only other option I can come up with is to just put the testing XML data in code, rather than loading it from a file. I would rather not do this.

  • What to do with a big image that's slowing website loading down significantly

    - by Dave
    Hi I'm working on a website that's already been designed by someone else. The designer has used a big image (900x700 100KB) which contains a big logo right across the top, then the background for two columns. This image loads every time a page is loaded as it forms the basis for the website. What should I do with it to improve loading time? I'm considering splitting it up into two or more images, especially the logo on the top. Does splitting up images like that decrease loading time in any significant way? Thanks -edit: Also, all the images are .jpg, would changing this to .gif or .png help anything?

    In a PowerPoint presentation, how do I make an object (say a rectangle or a circle) to disappear when I click on it? I have more than one such objects in my presentation and I have a picture behind each of these. So, when I click an object, that object must disappear and the photo behind that should be displayed. How do I do it?

  • Need a regular expression to parse a text body

    - by Ali
    Hi guys, I need a regular expression to parse a body of text. Basically assume this that we have text files and each of which contains random text but within the text there would be lines in the following formats - basically they are a format for denoting flight legs. eg: 13FEB2009 BDR7402 1000 UUBB 1020 UUWW FLT This line of text is always on one line The first word is a date in the format DDMMMYYYY Second word could be of any length and hold alphanumeric characters third word is the time in format HHMM - its always numeric fourth word is a location code - its almost always just alphabets but could also be alphanumeric fifth word is the arrival time in format HHMM - its always numeric sixth word is a location code - its almost always just alphabets but could also be alphanumeric Any words which follow on the same line are just definitions A text file may contain among lots of random text information one or more such lines of text. I need a way to be able to extract all this information i.e just these lines within a text file and store them with their integral parts separated as mentioned in an associative array so I have something like this: array('0'=>array('date'=>'', 'time-dept'=>'', 'flightcode'=>'',....)) I'm assuming regular expressions would be in order here. I'm using php for this - would appreciate the help guys :)

  • Model Binding with Parent/Child Relationship

    - by user296297
    I'm sure this has been answered before, but I've spent the last three hours looking for an acceptable solution and have been unable to find anything, so I apologize for what I'm sure is a repeat. I have two domain objects, Player and Position. Player's have a Position. My domain objects are POCOs tied to my database with NHibernate. I have an Add action that takes a Player, so I'm using the built in model binding. On my view I have a drop down list that lets a user select the Position for the Player. The value of the drop down list is the Id of the position. Everything gets populated correctly except that my Position object fails validation (ModelState.IsValid) because at the point of model binding it only has an Id and none of it's other required attributes. What is the preferred solution for solving this with ASP.NET MVC 2? Solutions I've tried... Fetch the Position from the database based on the Id before ModelState.IsValid is called in the Add action of my controller. I can't get the model to run the validation again, so ModelState.IsValid always returns false. Create a custom ModelBinder that inherits from the default binder and fetch the Position from the database after the base binder is called. The ModelBinder seems to be doing the validation so if I use anything from the default binder I'm hosed. Which means I have to completely roll my own binder and grab every value from the form...this seems really wrong and inefficient for such a common use-case. Solutions I think might work, I just can't figure out how to do... Turn off the validation for the Position class when used in Player. Write a custom ModelBinder leverages the default binder for most of the property binding, but lets me get the Position from the database BEFORE the default binder runs validation. So, how do the rest of you solve this? Thanks, Dan P.S. In my opinion having a PositionId on Player just for this case is not a good solution. There has to be solvable in a more elegant fashion.

  • Can't Change The Content of a Ajax Control After CallBack

Hi, printAlternativesFromAirport method should change an accordion panel after the callback but it doesn't. Is there anything that i could set to fix this problem ? There should be stg with the page lifecycle but i can't figure it out ! Thanks

  • Iterating Oracle collections of objects with out exploding them

    - by Scott Bailey
    I'm using Oracle object data types to represent a timespan or period. And I've got to do a bunch of operations that involve working with collections of periods. Iterating over collections in SQL is significantly faster than in PL/SQL. CREATE TYPE PERIOD AS OBJECT ( beginning DATE, ending DATE, ... some member functions...); CREATE TYPE PERIOD_TABLE AS TABLE OF PERIOD; -- sample usage SELECT <<period object>>.contains(period2) FROM TABLE(period_table1) t The problem is that the TABLE() function explodes the objects into scalar values, and I really need the objects instead. I could use the scalar values to recreate the objects but this would incur the overhead of re-instantiating the objects. And the period is designed to be subclassed so there would be additional difficulty trying to figure out what to initialize it as. Is there another way to do this that doesn't destroy my objects?

  • Modify python USB device driver to only use vendor_id and product_id, excluding BCD

    - by Tony
    I'm trying to modify the Android device driver for calibre (an e-book management program) so that it identifies devices by only vendor id and product id, and excludes BCD. The driver is a fairly simply python plugin, and is currently set up to use all three numbers, but apparently, when Android devices use custom Android builds (ie CyanogenMod for the Nexus One), it changes the BCD so calibre stops recognizing it. The current code looks like this, with a simple list of vendor id's, that then have allowed product id's and BCD's with them: VENDOR_ID = { 0x0bb4 : { 0x0c02 : [0x100], 0x0c01 : [0x100]}, 0x22b8 : { 0x41d9 : [0x216]}, 0x18d1 : { 0x4e11 : [0x0100], 0x4e12: [0x0100]}, 0x04e8 : { 0x681d : [0x0222]}, } The line I'm specifically trying to change is: 0x18d1 : { 0x4e11 : [0x0100], 0x4e12: [0x0100]}, Which is, the line for identifying a Nexus One. My N1, running CyanogenMod 5.0.5, has the BCD 0x0226, and rather than just adding it to the list, I'd prefer to eliminate the BCD from the recognition process, so that any device with vendor id 0x18d1 and product id 0x4e11 or 0x4e12 would be recognized. The custom Android rom doesn't change enough for the specifics to matter. The syntax seems to require the BCD in brackets. How can I edit this so that it matches anything in that field?

  • In a digital photo, detecting if a mountain is obscured by clouds.

    - by Gavin Brock
    The problem I have a collection of digital photos of a mountain in Japan. However the mountain is often obscured by clouds or fog. What techniques can I use to detect that the mountain is visible in the image? I am currently using Perl with the Imager module, but open to alternatives. All the images are taken from the exact same position - these are some samples. My naïve solution I started by taking several horizontal pixel samples of the mountain cone and comparing the brightness values to other samples from the sky. This worked well for differentiating good image 1 and bad image 2. However in the autumn it snowed and the mountain became brighter than the sky, like image 3, and my simple brightness test started to fail. Image 4 is an example of an edge case. I would classify this as a good image since some of the mountain is clearly visible.

  • Monitor files similar to System Internal's/Microsoft's FileMon/Process Monitor

    - by Tom1952
    I need to generate an event when a file is closed by another app. Unfortunately, ReadDirectoryChangesW doesn't report the close event. It would be possible for me to poll (with a TTimer) any file that reported by ReadDirectoryChangesW as modified, waiting for it to be closed (using CreateFile to detect this). However, what I'd prefer is a completely event driven solution. Is there a way to hook system calls and detect all file closing events? I simply want to know the path & name of any file that has just been closed.
