  • Boost ForEach Question

    - by bobber205
    Trying to use something like the below with a char array but it doesn't compile. But the example with short[] works fine. Any idea why? :) char someChars[] = {'s','h','e','r','r','y'}; BOOST_FOREACH(char& currentChar, someChars) { } short array_short[] = { 1, 2, 3 }; BOOST_FOREACH( short & i, array_short ) { ++i; }

  • Java: Help constructing a fillTextFields() method

    - by Holly
    I have a Java project where I am to connect to a database and create buttons (next, new, save, delete, previous) to navigate through the database content where there are appropriate text fields and labels for the specific information. I'll use the code below as an example (each button is set up very similar)... I have it as follows: JButton jbtnNext = new JButton("Next ->"); jbtnNext.addActionListener(this); if (e.getSource() == jbtnNext) jbtnNext_Click(); private void jbtnNext_Click() { JOptionPane.showMessageDialog(null, "Next" ,"Button Pressed", JOptionPane.INFORMATION_MESSAGE); try { if (rset.next()) { fillTextFields(true); }else{ //Display result in a dialog box JOptionPane.showMessageDialog(null, "Not found"); } } catch (SQLException ex) { ex.printStackTrace(); } } The professor gave the following outline of logic to construct the fillTextFields() method: Construct the method to provide reusable code that would fill the JTextFields on the GUI with appropriate values from current record from the database (when "Previous or "Next" buttons are pressed) or blank values (when the new Button is pressed). To determine when the current record was to provide values (next and previous) or the value would be blank (new button) pass a boolean argument into the method. If data from the current record was to be used as fill values, pass true for both previous and next button code after moving the record pointer. If the new button was pressed and want to fill with blank values, pass false to the method. Inside the method, use a conditional expression to evaluate the boolean variable. If true, The appropriate get----() resultset method is used to fill the JTextFields. If false, fill them with "". The .setText() method of the JTextField is used to fill each JTextField. Make sure the fillTextFields method throws the appropriate exception. I understand and have the previous and next button methods passing true, while the new button method is passing false, but I don't quite understand how to set up the fillTextFields() method correctly or how to "throw the appropriate exception"... Any help would really be appreciated, thank you!

    I am adding a modal view using the following code: [self presentModalViewController:phrasesEditor animated:YES]; How can I make the modal view semi-transparent so that the superview "shines" through?

I wanna turn my URLs from www.example.com/book.php?book=title into something like this, if it is possible of course: www.example.com/book/title Notice that the title of the books are unique and cannot be repeated.

  • Having Latest Tests Results info in the notified email with Hudson

    - by Roberto
    I have a project with a lot of tests failing, so it would be great for me to receive by email the number of failed tests compare from the latest build. What i need is just the info that appears in the project's page by the test results link: Latest Test Result (10 failures / -2) Is this possible? I've already tried the email-ext plugin, but it is not telling me that info (I can have the list of failing tests with output etc., but I really just need that info above). Any ideas?

  • Expectations for NTFS file recovery

    - by Fred Hamilton
    Yesterday I booted my XP system, and as I looked up a minute later I saw the light blue screen and tail-end of that pre-boot diskcheck Windows sometimes does if it finds an error (or was previously told to run a diskcheck drung the next boot). I didn't worry about it at the moment... But then I looked at my "scratch" disk, which was a 70% full, 750GB hard disk...and it now looks like it has been freshly formatted. It doesn't have a single file on it, just the hidden "System Volume Information" file and 750GB of freedom from data. I looked at some of the recovery tools from the Free NTFS partition recovery question and decided to try PC INSPECTOR™ File Recovery 4.x initially. It ran overnight and afterwards returned a list of thousands of files it could recover. The odd thing was that the filenames were lost, but the file extensions were not (WTF?). And all of the files were exactly 1,472kB in size. I recovered a dozen PDFs as a test, and 80% of them displayed OK despite being padded out to 1.5MB (though I assume any files 1472kB are hosed). My primary question is: Is this the best I can expect from any file recovery software when trying to recover NTFS files? Or is there perhaps something better out there? I assume this is as good as it gets, but wanted to check in with the experts first. Bonus questions: What might have happened to my drive? I didn't intentionally format it. I've never seen a disk error cause the drive to suddenly become a clean, reformatted drive. Could some malicious/confused software have told my PC to format my disk on reboot? Is that even a function Windows XP has? Why can the file extensions be recovered but not the filename? Does NTFS really treat them as separate entities? I thought I had 8.3 naming turned off, but maybe that had something to do with it. Or maybe it looks at the data in the file and guesses the extension?

  • Recover harddrive data

    - by gameshints
    I have a dell laptop that recently "died" (It would get the blue screen of death upon starting) and the hard drive would make a weird cyclic clicking noises. I wanted to see if I could use some tools on my linux machine to recover the data, so I plugged it into there. If I run "fdisk" I get: Disk /dev/sdb: 20.0 GB, 20003880960 bytes 64 heads, 32 sectors/track, 19077 cylinders Units = cylinders of 2048 * 512 = 1048576 bytes Disk identifier: 0x64651a0a Disk /dev/sdb doesn't contain a valid partition table Fine, the partition table is messed up. However if I run "testdisk" in attempt to fix the table, it freezes at this point, making the same cyclical clicking noises: Disk /dev/sdb - 20 GB / 18 GiB - CHS 19078 64 32 Analyse cylinder 158/19077: 00% I don't really care about the hard drive working again, and just the data, so I ran "gpart" to figure out where the partitions used to be. I got this: dev(/dev/sdb) mss(512) chs(19077/64/32)(LBA) #s(39069696) size(19077mb) * Warning: strange partition table magic 0x2A55. Primary partition(1) type: 222(0xDE)(UNKNOWN) size: 15mb #s(31429) s(63-31491) chs: (0/1/1)-(3/126/63)d (0/1/32)-(15/24/4)r hex: 00 01 01 00 DE 7E 3F 03 3F 00 00 00 C5 7A 00 00 Primary partition(2) type: 007(0x07)(OS/2 HPFS, NTFS, QNX or Advanced UNIX) (BOOT) size: 19021mb #s(38956987) s(31492-38988478) chs: (4/0/1)-(895/126/63)d (15/24/5)-(19037/21/31)r hex: 80 00 01 04 07 7E FF 7F 04 7B 00 00 BB 6F 52 02 So I tried to mount just to the old NTFS partition, but got an error: sudo mount -o loop,ro,offset=16123904 -t ntfs /dev/sdb /mnt/usb NTFS signature is missing. Ugh. Okay. But then I tried to get a raw data dump by running dd if=/dev/sdb of=/home/erik/brokenhd skip=31492 count=38956987 But the file got up to 59885568 bytes, and made the same cyclical clicking noises. Obviously there is a bad sector, but I don't know what to do about it! The data is still there... if I view that 57MB file in textpad... I can see raw data from files. How can I get my data back? Thanks for any suggestions, Solution: I was able to recover about 90% of my data: Froze harddrive in freezer Used Ddrescue to make a copy of the drive Since Ddrescue wasn't able to get enough of my drive to use testdisk to recover my partitions/file system, I ended up using photorec to recover most of my files

  • Free NTFS partition recovery

    - by Andrei Tanasescu
    I have a 1Tb disk which was partitioned into a ~700gb ntfs disk and a 300gb HFS+ (mac os X). I've accidentally allowed mac os x to wipe the hard-disk and create a single HFS+ partition over the hard-drive. I want to recover my NTFS partition. TestDisk fails to find the NTFS partition, but the DiskInternals solution does find my files. Are there any free alternatives to DIskInternals Partition recovery solution? THe tool should simply go block by block and attempt to reconstruct the files.

  • Are there any free Windows based BluRay players out there?

    - by joshcomley
    I have a BluRay drive in my PC, and I'm wondering what the cheapest way to actually get it to play a movie is (I didn't expect this to be trouble). I'm using Windows 7. I installed CyberLink PowerDVD 8 (I'm currently downloading 10 but it's taking a very, very long time) and I get the below "error" when trying to watch a BluRay movie: CyberLink PowerDVD is not able to play the protected content on your digital output device. Please switch to an analog output (VGA, D-Sub) and then try again. I can't get VLC to play it and my research yields no plugins for VLC to enable it either - unless I'm vastly missing something. Help!

  • Writing at the end of file

    - by user342534
    Hi, I'm working on a system that requires high file I/O performance (with C#). Basically, I'm filling up large files (~100MB) from the start of the file until the end of the file. Every ~5 seconds I'm adding ~5MB to the file (sequentially from the start of the file), on every bulk I'm flushing the stream. Every few minutes I need to update a structure which I write at the end of the file (some kind of metadata). When flushing each one of the bulks I have no performance issue. However, when updating the metadata at the end of the file I get really low performance. My guess is that when creating the file (which also should be done extra fast), the file doesn't really allocates the entire 100MB on the disk and when I flush the metadata it must allocates all space until the end of file. Guys/Girls, any Idea how I can overcome this problem? Thanks a lot!

  • Get the path to Django itself

    - by andybak
    I've got some code that runs on every (nearly) every admin request but doesn't have access to the 'request' object. I need to find the path to Django installation. I could do: import django django_path = django.__file__ but that seems rather wasteful in the middle of a request. Does putting the import at the start of the module waste memory? I'm fairly sure I'm missing an obvious trick here.

  • XNA popup text dialog

    - by mazzzzz
    Hey guys, I am working on a game, and wanted to add a screen that would open when the user clicked on certain objects. The screen would be laid out to have an image on the left, a title on the top right, and text below the title. I have a few problems with this, 1) How would I create the popup box? (preferably with rounded edges) 2) How would I wrap the text (in front of the picture, but not outside the popup-box, I may even need vertical scroll bars) 3) How would I account for different screen resolutions (would they even make a difference?) Thanks for any and all help, Max

  • Hard Disk recovery

    - by Shaihi
    I have 3 disks of the same type model and year of production. All the disks were used part of a generic solution of an IBM server solution. My problem is that all 3 disks suffered the same malfunction at the same exact time and are now dis-functional. I went to two different expert's laboratories and got the same answer: To recover the data they need another identical disk from which they can take spare parts. Can my case really be that clinical? Anyway, I am not sure if this question belongs to this forum, but I am looking to buy the following disk: IIBM ESERVER XSERIES IBM P/N 24P3707 IBM FRU 24P3708 146.8GB USCSI 10K RPM PART NOMBER 9V2005-027 I already bought a disk with the same part number, but the labs said that apparently I need a disk that was manufactured in the same factory. That means that all the numbers have to be exactly the same. If anybody know where I can purchase such a disk (the information on the lost disks is really important to me), please tell me the place.

  • Not having address/phone number in WHOIS database?

    - by HighCommander4
    When I sign up for an account with a domain name registrar like 10dollar.ca, it asks for my address and phone number. Will these show up when someone does a WHOIS lookup on my domain name? I noticed that when you do a WHOIS lookup on some websites (e.g. http://www.chrismanieri.ca), no address/phone number comes up. I want mine to be like that, too (don't want my address/phone number exposed to the public).

  • Recover data from hard drive with partitions (but not most data) overwritten

    - by Macha
    I have a 500GB hard drive I've been keeping around to recover data from that I removed from a failing NAS drive that got sort of... erratic at the end. I finally got rid of the NAS when during a firmware update it removed the partition table. Fast forward to a week ago, when I was building a new PC, and a mixup resulted in me placing the hard drive in question in the new PC and installing Windows XP on the first 100GB. I'm presuming any data on that first 100GB is now gone, but for the rest of it, is there any way I can recover it at home, as professional data recovery is currently too expensive? I have a blank 1TB HDD if I can store any images of that hard drive on. The problem was definitely with the NAS and not the hard drive, as the hard drive had a successful install of Windows when mistakenly place in the new PC, and there were capacitors in the NAS's circuitry clearly broken. The data I want to recover (in order of priority) is: High: Some jpgs of family photos. Medium: Some RAW files. (There are also jpg versions of all of these) Low: Some mp3s, avis and ISOs, I can re-rip most of these if need be, but it'd be handy not to have to. (I don't need a backup lecture, and if you can hold it in from nagging Jeff Atwood for it, you can hold it in from nagging me for it) In short: The partition tables are gone and overwritten. The data is not overwritten, except for an amount equal to the size of a Windows XP SP3 installation.
