  • linq query - The method or operation is not implemented.

    - by Dejan.S
    I'm doing the Rob Conery mvc storefront and at one place I'm suppose to get categories but I get an error with this linq query and I can not get why. It's exactly the same as his. var culturedName = from ct in ReadOnlyContext.CategoryCultureDetails where ct.Culture.LanguageCode == System.Globalization.CultureInfo.CurrentUICulture.TwoLetterISOLanguageName select new { ct.CategoryName, ct.CategoryId }; return from c in ReadOnlyContext.Categories join cn in culturedName on c.CategoryId equals cn.CategoryId select new Core.Model.Category { Id = c.CategoryId, Name = cn.CategoryName, ParentId = c.ParentId ?? 0, Products = new LazyList<Core.Model.Product>(from p in GetProducts() join cp in ReadOnlyContext.Categories_Products on p.Id equals cp.ProductId where cp.CategoryId == c.CategoryId select p) }; its the return query that mess things up. I have checked and the culturename actually gets data from the database. Appricate your help

  • What causes my borderless C++/CLI app to crash when overriding WndProc?

    - by Ste
    I use a form with border NONE. I need to override WndProc for resize and move form. However, using this code, my app crashes! static const int WM_NCHITTEST = 0x0084; static const int HTCLIENT = 1; static const int HTCAPTION = 2; protected: virtual void Form1::WndProc(System::Windows::Forms::Message %m) override { switch (m.Msg) { case WM_NCHITTEST: if (m.Result == IntPtr(HTCLIENT)) { m.Result = IntPtr(HTCAPTION); } break; } Form1::WndProc(m); } virtual System::Windows::Forms::CreateParams^ get() override { System::Windows::Forms::CreateParams^ cp = __super::CreateParams; cp->Style |= 0x40000; return cp; } How can I fix my code not to crash but still allow my form to be moved and resized?

  • MacPorts: violation of the ports-filesystem hierarchy in the destroot phase

    - by Dawood
    I'm in the process of developing a Portfile for my application and I'm running into problems during the destroot phase. According to the MacPorts guide, the destroot phase executes the following command: make install DESTDIR=${destroot} I think I may be misunderstanding how this is supposed to work in the Makefile. My application is very simple and the install rule only needs to copy a couple of directories to the DESTDIR so it is specified as follows: install: cp -R bin $(DESTDIR)/bin cp -R lib $(DESTDIR)/lib cp -R cfg $(DESTDIR)/cfg However, when I try to do a MacPort installation of my application, I get the following warnings: ---> Staging test into destroot Warning: violation by /bin Warning: violation by /lib Warning: violation by /cfg Warning: test violates the layout of the ports-filesystems! How do I fix this? Am I misunderstanding how the DESTDIR variable is used in the install rule or missing something altogether?

  • EBS: OPP Out of memory issue...

    - by ashish.shrivastava
    FO Processor is little more hungry for memory compare to other Java process. If XSLT scalable option is not set and the same time your RTF template is not well optimized definitely you are going to hit Out of memory exception while working with large volume of data. If the memory requirement is not too bad, you can set the OOP Heap size using following SQL queries. Check the current OPP JVM Heap size using following SQL query SQL select DEVELOPER_PARAMETERS from FND_CP_SERVICES where SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUES where CONCURRENT_QUEUE_NAME = 'FNDCPOPP' DEVELOPER_PARAMETERS ----------------------------------------------------- J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx512m Set the JVM Heap size using following SQL query SQL update FND_CP_SERVICES set DEVELOPER_PARAMETERS = 'J:oracle.apps.fnd.cp.gsf.GSMServiceController:-mx2048m' where SERVICE_ID = (select MANAGER_TYPE from FND_CONCURRENT_QUEUES where CONCURRENT_QUEUE_NAME = 'FNDCPOPP'); SQLCommit; . You need to restart the Concurrent Manager to make it effective. If this does not resolve the issue, You need to optimize RTF template and set the XSLT scalable option true.

  • How to copy a folder from /home/kevin to /opt

    - by lambda23
    I have a new computer installed with Ubuntu 12.04. Then I want to install wireless driver named compat-wireless-3.5-3. Before that, the driver folder to /home/kevin. I want to install it on /opt directory. Before install the driver, i want to copy the driver folder from /home/kevin to /opt. I try to use ordinary copy (Right Click Copy Paste), but the paste is blured. After that, i tried using this on terminal: sudo cp /home/kevin/compat-wireless-3.5-3 /opt But i get this command: cp: omitting directory `home/kevin/compat-wireless-3.5-3' What does the command mean? I can't copy the driver until now.

  • Bash prompt doesn't print until I interact with console again

    - by durron597
    I don't even know where to begin to diagnose this one. Usually, when a command finishes, the prompt prints itself for the next command. However, that is not happening. Hard to explain with words, I'll just use an example: User@Machine:~$ cp /mnt/mountname/directory/textfile.txt . After waiting several seconds (far too long for this operation on a small file) I press Enter, and see: User@Machine:~$ cp /mnt/mountname/directory/textfile.txt . User@Machine:~$ User@Machine:~$ So clearly the operation had finished, but the prompt didn't display... until I pressed enter, and then BOTH prompts instantly displayed. This error does not happen with commands like cd.

  • Commandline shortcut for current directory similar to ~ for home directory?

    - by NES
    When i use the cp or move command in a terminal window, i'm currently with bash in a certain folder like this. NES@server:~/Desktop/dir1$ And now i wanna copy a file from here ~/anotherdir/dir2 into the current chosen folder in bash (dir1) i would use the command cp ~/anotherdir/dir2/file ~/Desktop/dir1 does a shortcut string exist to refer to the current chosen directory? So that in this example i don't have to provide the full path to the target dir, but the command knows it should use the current chosen directory in bash? i.e. as ~ stands for the home directory?

  • How can I keep directories in sync

    - by Guillaume Boudreau
    I have a directory, dirA, that users can work in: they can create, modify, rename and delete files & sub-directores in dirA. I want to keep another directory, dirB, in sync with dirA. What I'd like, is a discussion on finding a working algorithm that would achieve the above, with the limitations listed below. Requirements: 1. Something asynchronous - I don't want to stop file operations in dirA while I work in dirB. 2. I can't assume that I can just blindly rsync dirA to dirB on regular interval - dirA could contain millions of files & directories, and terrabytes of data. Completely walking the dirA tree could take hours. Those two requirements makes this really difficult. Having it asynchronous means that when I start working on a specific file from dirA, it might have moved a lot since it appeared. And the second limitation means that I really need to watch dirA, and work on atomic file operations that I notice. Current (broken) implementation: 1. Log all file & directory operations in dirA. 2. Using a separate process, read that log, and 'repeat' all the logged operations in dirB. Why is it broken: echo 1 > dirA/file1 # Allow the 'log reader' process to create dirB/file1: log = "write dirA/file1"; action = cp dirA/file1 dirB/file1; result = OK echo 1 > dirA/file2 mv dirA/file1 dirA/file3 mv dirA/file2 dirA/file1 rm dirA/file3 # End result: file1 contains '1' # 'log reader' process starts working on the 4 above file operations: log = "write file2"; action = cp dirA/file2 dirB/file2; result = failed: there is no dirA/file2 log = "rename file1 file3"; action = mv dirB/file1 dirB/file3; result = OK log = "rename file2 file1"; action = mv dirB/file2 dirB/file1; result = failed: there is no dirB/file2 log = "delete file3"; action = rm dirB/file3; result = OK # End result in dirB: no more files! Another broken example: echo 1 > dirA/dir1/file1 mv dirA/dir1 dirA/dir2 # 'log reader' process starts working on the 2 above file operations: log = "write file1"; action = cp dirA/dir1/file1 dirB/dir1/file1; result = failed: there is no dirA/dir1/file1 log = "rename dir1 dir2"; action = mv dirB/dir1 dirB/dir2; result = failed: there is no dirA/dir1 # End result if dirB: nothing!

  • file copy error from system to cifs mount

    - by dwpriest
    When coping a file greater than 64kB from an Ubuntu server to a CIFS mounted windows share, most of the data is copied, but it seems the last chunk doesn't get copied. The size doesn't match, and the md5 check sums don't match. I have plenty of file space, but then I use cp, I get the following... cp: closing `cloudBackup/asdf.txt': No space left on device Using rsync, I get the following... rsync: close failed on "/home/fluffy/cloudBackup/.asdf.txt.qrBWe6": No space left on device (28) rsync error: error in file IO (code 11) at receiver.c(752) [receiver=3.0.8] rsync: connection unexpectedly closed (29 bytes received so far) [sender] rsync error: error in rsync protocol data stream (code 12) at io.c(601) [sender=3.0.8] I have full read/write permissions on the mounted share. I can copy locally and between the mount and system via SSH just fine. Any ideas? Thank you

  • No sound in World of Goo?

    - by user37805
    I installed WorldOfGooSetup.1.41.deb and it didn't work. There was a segmentation fault error (core dumped) in terminal. I fixed that with: sudo cp /usr/lib/x86_64-linux-gnu/libvorbis.so.* /opt/WorldOfGoo/libs32 sudo cp /usr/lib/x86_64-linux-gnu/libvorbis.so.* /opt/WorldOfGoo/libs64 That error is new for me as I have never had it before with previous releases of Ubuntu. The game starts now but no sound effects or music is played. I can hear music with my computer, videos, etc, so it is not a volume control problem. I am using ubuntu 12.04 final release.

  • Optimal file system type and mount options for an rsnapshot dedicated drive

    - by Nimmy Lebby
    We have an external USB 2 drive that we are using as a backup drive for our configuration. We use rsnapshot for the backups. It uses a few standard commands for managing snapshots: rm -rf: deletes expired snapshots mv: moves older snapshots down a slot cp -al: duplicates last snapshot to new slot rsync -a --delete --numeric-ids --relative: synchronizes new snapshot As you could see by the log below, the majority of the time is spent on the rm -rf and the cp -al steps: [25/Dec/2010:14:00:02] rsnapshot hourly: started [25/Dec/2010:14:00:02] echo 21012 > /var/run/rsnapshot.pid [25/Dec/2010:14:00:02] rm -rf /mnt/extdrive/snapshots/hourly.5/ [25/Dec/2010:14:15:48] mv /mnt/extdrive/snapshots/hourly.4/ /mnt/extdrive/snapshots/hourly.5/ [25/Dec/2010:14:15:48] mv /mnt/extdrive/snapshots/hourly.3/ /mnt/extdrive/snapshots/hourly.4/ [25/Dec/2010:14:15:48] mv /mnt/extdrive/snapshots/hourly.2/ /mnt/extdrive/snapshots/hourly.3/ [25/Dec/2010:14:15:48] mv /mnt/extdrive/snapshots/hourly.1/ /mnt/extdrive/snapshots/hourly.2/ [25/Dec/2010:14:15:48] cp -al /mnt/extdrive/snapshots/hourly.0 /mnt/extdrive/snapshots/hourly.1 [25/Dec/2010:14:23:32] rsync -a --delete --numeric-ids --relative /etc /mnt/extdrive/snapshots/hourly.0/sm4/ [25/Dec/2010:14:23:52] touch /mnt/extdrive/snapshots/hourly.0/ [25/Dec/2010:14:23:52] rm -f /var/run/rsnapshot.pid [25/Dec/2010:14:23:52] rsnapshot hourly: completed successfully My questions: I'm currently using ext4 for the filesystem. Maybe this is not the best choice from those available in Red Hat. Anyone have any recommendations that would speed up the process? The partition's mount options are sync,dirsync 1 2. Is there a way to optimize this since it's solely used for rsnapshot? Of course, reasoning would be greatly appreciated.

  • SSH Private Key Not Working in Some Directories

    - by uesp
    I have a strange issue where SSH won't properly connect with a private-key if the key file is in certain directories. I've setup the keys on a set of servers and the following command ssh -i /root/privatekey [email protected] works fine and I login to the given host without getting prompted by a password, but this command: ssh -i /etc/keyfiles/privatekey [email protected] gives me a password prompt. I've narrowed it down that this behavior occurs in only some sub-directories of /etc/. For example /etc/httpd1/ gives me a password prompt but /etc/httpd/ does not. What I've checked so far: All private key files used are identical (copied from the original file). The private key file and directories used have identical permissions. No relevant error messages in the server/client logs. No interesting debug messages from ssh -v (it just seems to skip the key file). It happens with connecting to different hosts. After more testing it is not the actual directory name. For example: mkdir /etc/test cp /root/privatekey /etc/test ssh -i /etc/test/privatekey [email protected] # Results in password prompt cp /root/privatekey /etc/httpd # Existing directory ls -ald test httpd # drwxr-xr-x 4 root root 4096 Mar 5 18:25 httpd # drwxr-xr-x 2 root root 4096 Mar 5 18:43 test ssh -i /etc/httpd/privatekey [email protected] # Results in *no* prompt rm -r test cp -R /etc/httpd /etc/test ssh -i /etc/test/privatekey [email protected] # Results in *no* prompt` I'm sure its just something simple I've overlooked but I'm at a loss.

  • Copy files from sub directories into one directory.

    - by Derek Organ
    Ok I have a bunch of files in this file structure format. /backup/daily/database1/database1-2011-01-01.sql /backup/daily/database1/database1-2011-01-02.sql /backup/daily/database1/database1-2011-01-03.sql /backup/daily/database1/database1-2011-01-04.sql /backup/daily/database1/database1-2011-01-05.sql /backup/daily/database1/database1-2011-01-06.sql /backup/daily/database1/database1-2011-01-07.sql /backup/daily/anotherdb/anotherdb-2011-01-01.sql /backup/daily/anotherdb/anotherdb-2011-01-02.sql /backup/daily/anotherdb/anotherdb-2011-01-03.sql /backup/daily/anotherdb/anotherdb-2011-01-04.sql /backup/daily/anotherdb/anotherdb-2011-01-05.sql /backup/daily/anotherdb/anotherdb-2011-01-06.sql /backup/daily/anotherdb/anotherdb-2011-01-07.sql /backup/daily/stuff/stuff-2011-01-01.sql /backup/daily/stuff/stuff-2011-01-02.sql /backup/daily/stuff/stuff-2011-01-03.sql /backup/daily/stuff/stuff-2011-01-04.sql /backup/daily/stuff/stuff-2011-01-05.sql /backup/daily/stuff/stuff-2011-01-06.sql /backup/daily/stuff/stuff-2011-01-07.sql And there are lots lots more. ultimately I want to import all the 2011-01-07.sql files into my mysql database. This works for one mysql -u root -ppassword < /backup/daily/database1/database1-2011-01-07.sql That will nicely restore that database from this backupfile. I want to run a process where it does this for all databases. So my plan is to first cp all 2011-01-07 sql files into a tmp dir e.g. cp /backup/daily/*/*2011-01-07*.sql /tmp/all The command above unfortunately isn't working I get an error: cp: cannot stat ..... No such file or directory So can you guys help me out with this. For bonus points if you can tell me how to do the next step which is import all databases in one command doing one at a time that would be great too. I really want to do these in two separate steps because I need to delete a few sql files manually from the tmp dir before I run the restore command. So I need: 1) command to copy all 2011-01-07 sql files to a tmp dir 2) command to import all those files in that dir into mysql I know its possible to do in one but for lots of reasons I really would prefer to do it in two steps.

  • Linux: Can't overwrite files on samba store

    - by jonescb
    I'm using CentOS 5.5 with smbclient 3.0.33-3.28-el5 (latest version in repo), and I can't overwrite files in my Samba store. I am not the admin for the Samba server, so there isn't anything I can do server side. But I do have write permission to the server. I know the server runs Windows XP or Server 2003; I don't know. I can delete the file, and then copy the new version over, but I can't overwrite it. Using the cp command I'll get this error: [jonescb@localhost ~]$ cp foo.txt /mnt/si_storage/foo.txt cp: cannot create regular file `/mnt/si_storage/foo.txt': No such file or directory` And if I edit a file on the server using vim, I can save it once, but if I save it again I get this: "/mnt/si_storage/foo.txt" E212: Can't open file for writing This is my /etc/fstab entry for the samba server: //192.168.1.2/SI_STORAGE /mnt/si_storage cifs username=myuser,password=mypass 0 0 Edit: I can overwrite files just fine on my XP machine. The CentOS box is the only one having problems.

  • Padding error when using RSA Encryption in C# and Decryption in Java

    - by Matt Shaver
    Currently I am receiving the following error when using Java to decrypt a Base64 encoded RSA encrypted string that was made in C#: javax.crypto.BadPaddingException: Not PKCS#1 block type 2 or Zero padding The setup process between the exchange from .NET and Java is done by creating a private key in the .NET key store then from the PEM file extracted, created use keytool to create a JKS version with the private key. Java loads the already created JKS and decodes the Base64 string into a byte array and then uses the private key to decrypt. Here is the code that I have in C# that creates the encrypted string: public string Encrypt(string value) { byte[] baIn = null; byte[] baRet = null; string keyContainerName = "test"; CspParameters cp = new CspParameters(); cp.Flags = CspProviderFlags.UseMachineKeyStore; cp.KeyContainerName = keyContainerName; RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cp); // Convert the input string to a byte array baIn = UnicodeEncoding.Unicode.GetBytes(value); // Encrypt baRet = rsa.Encrypt(baIn, false); // Convert the encrypted byte array to a base64 string return Convert.ToBase64String(baRet); } Here is the code that I have in Java that decrypts the inputted string: public void decrypt(String base64String) { String keyStorePath = "C:\Key.keystore"; String storepass = "1234"; String keypass = "abcd"; byte[] data = Base64.decode(base64String); byte[] cipherData = null; keystore = KeyStore.getInstance("JKS"); keystore.load(new FileInputStream(keyStorePath), storepass.toCharArray()); RSAPrivateKey privateRSAKey = (RSAPrivateKey) keystore.getKey(alias, keypass.toCharArray()); Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding"); cipher.init(Cipher.DECRYPT_MODE, privateRSAKey); cipherData = cipher.doFinal(data); System.out.println(new String(cipherData)); } Does anyone see a step missing or where the padding or item needs to be changed? I have done hours of reading on this site and others but haven't really found a concrete solution. You're help is vastly appreciated. Thanks. -Matt

  • makefile: execute one target from another target plus additional commands

    I have a makefile with something like the following targets: install: do a whole bunch of stuff to build and install dist: install cp README.txt $(INSTALL_DIR) zip $(INSTALL_DIR) I am trying to not repeat the commands from target install and make dist execute install first before executing its own commands. Calling make dist does indeed execute all commands from target install but then just stops and it does not execute its own commands, e.g. the cp. Am I missing something?

    hey, I have a firmware for an USB module I can already control by visual C. Now I want to port this to python. for this I need the octopus library which is written in c. I found a file called octopus_wrap which was created by SWIG! then I found a makefile which says: python2.5: swig -python -outdir ./ ../octopus.i gcc -fPIC -c ../../liboctopus/src/octopus.c gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.5 gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so python2.4: swig -python -outdir ./ ../octopus.i gcc -fPIC -c ../../liboctopus/src/octopus.c gcc -fPIC -c ../octopus_wrap.c -I /usr/include/python2.4 gcc -fPIC -shared octopus_wrap.o octopus.o /usr/lib/libusb.so -o _octopus.so win: gcc -fPIC -c ../../liboctopus/src/octopus.c -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include gcc -fPIC -c octopus_wrap.c -I /c/Python25/libs -lpython25 -I/c/Python25/include -I /c/Programme/libusb-win32-device-bin-0.1.10.1/include gcc -fPIC -shared *.o -o _octopus.pyd -L/c/Python25/libs -lpython25 -lusb -L/c/Programme/libusb-win32-device-bin-0.1.10.1/lib/gcc clean: rm -f octopus* _octopus* install_python2.4: cp _octopus.so /usr/local/lib/python2.4/site-packages/ cp octopus.py /usr/local/lib/python2.4/site-packages/ install_python2.5: cp _octopus.so /usr/local/lib/python2.5/site-packages/ cp octopus.py /usr/local/lib/python2.5/site-packages/ I dont know how to handle this but as far as I can see octopus.py and _octopus.so are the resulting output files which are relevant to python right? luckily someone already did that and so I put those 2 files to my "python26/lib" folder (hope it doesnt matter if it´s python 2.5 or 2.6?!) So when working with the USB device the octopus.py is the library to work with! Importing this file makes several problems: >>> Traceback (most recent call last): File "C:\Users\ameise\My Dropbox\µC\AVR\OCTOPUS\octopususb-0.5\demos\python \blink_status.py", line 8, in <module> from octopus import * File "C:\Python26\lib\octopus.py", line 7, in <module> import _octopus ImportError: DLL load failed: module not found. and here´s the related line 7 : import _octopus So there´s a problem considering the .so file! What could be my next step? I know that´s a lot of confusing stuff but I hope anyone of you could bring some light in my mind! thy in advance

Thank you!
