  • ODBC and NLS_LANG

    - by Michael S.
    Let's say that I've created two different program executables, e.g. in C++. For some reason, the two programs internals representation of text are different from each other. Let's say the first program is using text representation A and the other text representation B. It could be a specific 8-bit ANSI codepage, Unicode/UTF-8 or Unicode/UTF-16 or whatever. Now each program want to communicate text (add/retrieve data) to/from the same database table on a (database) server. Each program communicates with the database through ODBC. So the programs do not know what database system they they are communicating with. In this specific case through the database is actually a Oracle RDMS database and the database server administrator has setup the database to use UTF-8. On the system on which the programs are running an appropriate ODBC driver is available, so that the programs can connect through ODBC. Each program will treat and convert from the ODBC data type SQL_C_CHAR to its internal text representation appropriately. I assume that the programs cannot do no other than to assume a specific encoding returned for SQL_C_CHAR text. If not the programs has to be told which encoding that is. For Oracle, I know that the NLS_LANG environment variable can be used on the client. I assume it affects the ODBC driver (related to SQL_C_CHAR) to convert from a specific encoding (as given by NLS_LANG) to the internal encoding of the database (in this example UTF-8) and vice-versa. If the machine running my programs are having a NLS_LANG this setting will affect the byte sequences returned for SQL_C_CHAR so my programs cannot suddenly assume a specific encoding for the text returned via SQL_C_CHAR. Is it possible to setup the ODBC connection (preferably programmatically at runtime), so that it takes care of text conversions appropriately for the two programs, i.e. from/to representation to/from UTF-8 and from/to representation B to/from UTF-8? Regards, /Michael PS. As the programs are connecting through ODBC I don't think it would be nice that they should now anything about NLS_LANG as this is a Orcacle specific environment variable.

  • Pull/Clone a svn repository into hg with new default branch name?

    - by TheLQ
    I'm forking a project's SVN repo and need to integrate into my Mercurial repo. To keep things simple I have a local hgsubversion repo and a local hg repo. However both the mercurial and hgsubversion repo uses default as their default branch name. My goal here is to put the original code and updates on one branch and my code on the default branch However I have yet to be able to do this. W:\programming\tcsite-svn-test>hg clone http://*HG_SITE*/hg . no changes found updating to branch default 0 files updated, 0 files merged, 0 files removed, 0 files unresolved W:\programming\tcsite-svn-test>hg branch blizzard marked working directory as branch blizzard W:\programming\tcsite-svn-test>hg commit W:\programming\tcsite-svn-test>hg log changeset: 0:be13a9580df0 branch: blizzard tag: tip user: Leon Blakey <[email protected]> date: Fri Jan 14 23:44:25 2011 -0500 summary: Created Blizzard Branch W:\programming\tcsite-svn-test>hg pull http://*SVN_SITE*/svn/ pulling from http://*SVN_SITE*/svn/ .... pulled 23 revisions (run 'hg update' to get a working copy) W:\programming\tcsite-svn-test>hg branch blizzard W:\programming\tcsite-svn-test>hg branches default 23:93642a8890ab <------ blizzard 0:be13a9580df0 Not surprisingly, hgsubversion puts pulled commits into the default branch when I really need them in the blizzard branch. From the docs, there is no way to rename the branch that a commit came from. Frustratingly I can't even come up with a way to do it on a repo with only the hgsubversion repo being pulled from, nothing else. All commits are tied to that one branch no matter what. Is there any suggestions on how to pull changes from an SVN repo and rename the branch to something else?

  • How can I dynamically set the default namespace declaration of an XSLT transformation's output XML?

    - by Paralife
    I can do it, but not for the default namespace, using the <xsl:namespace>. If I try to do it for the default namespace: <xsl:namespace name="" select"myUri"/> it never works. It demands that I explicitly define the namespace of the element to be able to use the above null prefix declaration. The reason I want this is because I have a task to transform an input XML file to another output xml. The output XML has many elements and i dont want to have to explicitly set the namespace for every element. Thats why I want to set the default and never bother again. But the default must be computed from some data in the source XML. It does not change during the whole transformation, but it is dependent on input XML data. Any solution? EDIT 1: To sup up: I want to create a namespace dynamically and set it to be the default namespace of the output xml document. The uri of the namespace is derived from some data in the input XML. If I use <xsl:namespace> in my root output element, I cannot create a default namespace for it, only a prefixed one. And even with the prefixed one, it does not propagate to children.

  • What are the factors that determine the default frequency of a shader call?

    - by user827992
    After i have been played for some days with various vertex and fragments shaders seems clear to me that this programs are called by the GPU at every and each rendering cycle, the problem is that I can't really quantify this frequency and I can't tell if is based on some default values or not because I don't have a big collection of hardware right now to do extensive tests. For what i know the answer could be really trivial like "it's the same of the refresh rate of your monitor", but i would like some good answers on that to be clear on this. For instance looks really odd to me that all the techniques used to control the amount of FPS that i have seen until now uses a call for the OpenGL function glutGet(GLUT_ELAPSED_TIME) to retrieve a value in ms about when the rendering started but I have to relies on the CPU to do the math. Why I can't set an FPS value in OpenGL if OpenGL clearly has a counter and a timer/clock? PS I'm referring to OpenGL 3.0+

  • How to manipulate default document with rewrite module on IIS7?

    - by eugeneK
    Until few month ago i've been using IIS 6 where i could add different Default Documents to each websites which are physically same directory. Since II7 which adds Default Document value to web config i couldn't use such technique as web.config was changed for all the directory. So I've found simple solution with rewrite module to change Default Document for each domain <defaultDocument enabled="false" /> <rewrite> <rewriteMaps> <rewriteMap name="ResolveDefaultDocForHost"> <add key="site1.com" value="Default1.aspx" /> <add key="site2.com" value="Default2.aspx" /> </rewriteMap> </rewriteMaps> <rules> <rule name="DefaultDoc Redirect If No Trailing Slash" stopProcessing="true"> <match url=".*[^/]$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" /> </conditions> <action type="Redirect" url="{R:0}/" /> </rule> <rule name="PerHostDefaultDocSlash" stopProcessing="true"> <match url="$|.*/$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" /> <add input="{ResolveDefaultDocForHost:{HTTP_HOST}}" pattern="(.+)" /> </conditions> <action type="Rewrite" url="{R:0}{C:1}" appendQueryString="true" /> </rule> </rules> </rewrite> Now i've got two other issues. first of all i can't use canonical url rewrite, if i set one then site1.com and site2.com redirected to www.site1.com instead of having www. for each. second problem is that there is a directory within site1' and site2' physical directory called members in which Default.aspx is always a Default Document doesn't matter which domain name was used. It doesn't work as well. Please help me with this issue because i've never thought i will get such problem with supposed to be better IIS7...

  • Is it possible to set Transmission to show list of files as collapsed by default?

    - by Rasmus
    When downloading a torrent with a large folder hierarchy, I often find myself losing overview of the content of the torrent as Transmission shows the entire folder structure expanded under Properties > Files. Most annoyingly, if one collapses the tree and closes the dialog, the tree will be expanded again if one re-access it. Is it somehow possible to set Transmission to show torrent content as collapsed by default?

  • How can I make the function keys the default on a Logitech K760 Bluetooh keyboard?

    - by Chas. Owens
    I had hoped that solaar would help, but it seems to only work for the Logitech wireless devices that use Logitech's proprietary scheme. I have Bluetooth keyboard (K760). I know it can be told to use the function keys (rather than the media keys) by default because I can do it on under OS X with software from Logitech. Just remapping the keys won't work as F1, F2, and F3 are special in that they switch which Bluetooth device I connect to and the keys are not sent to the OS.

  • Will default applications be automatically changed during release upgrade?

    - by Jasper Loy
    Suppose LibreOffice and Banshee are set to replace OpenOffice and Rhythmbox in Natty Narwhal. Of course doing a fresh install will give me these new applications to be the default ones. However if I choose to upgrade via the update manager, will the old applications be uninstalled and the new ones installed automatically, or do I have to do these manually so that I get the same experience as a fresh install?

  • Why am I asked for default's keyring at startup?

    - by Nicoco
    I'm prompted for default's keyring at every boot since 11.10 upgrade, even though I don't see any application I have needing at startup (I have no wifi, and disabled gwibber-service) How can I know which application is requesting it ? How can I disable it ? I can't even move any window until I enter the password, and sometimes entering the password even crashes X (bug reported here : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/882955)

  • What are the names of default indicators in Ubuntu 11.10?

    - by sup
    How are they called? It is useful for configuring them via dconf, reporting bugs and so on but hard to find out. I remember there was similar wuestion for 11:04 but cannot find it. These are the indicators on my system: There are ten, the last one on the left is Tomboy, the rest is more or less default (the second from the left is displayed only if more than one keybord layout is used). What are their names?

  • Vagrant ssh fails with VirtualBox

    vagrant up fails when it gets to the ssh part: myterminal$ vagrant up [default] VM already created. Booting if its not already running... [default] Running any VM customizations... [default] Clearing any previously set forwarded ports... [default] Forwarding ports...

Please verify the VM successfully booted by looking at the VirtualBox GUI. Then when I subsequently try and connect using vagrant ssh or vagrant reload or similar, I get this: myterminal$ vagrant reload [default] Attempting graceful shutdown of linux... SSH connection was refused! This usually happens if the VM failed to boot properly. Some steps to try to fix this: First, try reloading your VM with `vagrant reload`, since a simple restart sometimes fixes things. If that doesn't work, destroy your VM and recreate it with a `vagrant destroy` followed by a `vagrant up`. If that doesn't work, contact a Vagrant maintainer (support channels listed on the website) for more assistance. Please help! I'm really stumped. Kind regards, Luke

  • syslog-ng and nging logs to mysql

    - by Katafalkas
    So couple of days ago I asked how to log php and nginx logs to centralized MySQL database, and m0ntassar gave a perfect answer :) cheer ! The problem I am facing now is that I can not seem to get it working. syslog-ng version: # syslog-ng --version syslog-ng 3.2.5 This is my nginx log format: log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; syslog-ng source: source nginx { file( "/var/log/nginx/tg-test-3.access.log" follow_freq(1) flags(no-parse) ); }; syslog-ng destination: destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("superpasswd") database("syslog") table("nginx") columns("remote_addr","remote_user","time_local","request","status","body_bytes_sent","http_ referer","http_user_agent","http_x_forwarded_for") values("$REMOTE_ADDR", "$REMOTE_USER", "$TIME_LOCAL", "$REQUEST", "$STATUS","$BODY_BYTES_SENT", "$HTTP_REFERER", "$HTTP_USER_AGENT", "$HTTP_X_FORWARDED_FOR")); }; MySQL table for testing purposes: CREATE TABLE `nginx` ( `remote_addr` varchar(100) DEFAULT NULL, `remote_user` varchar(100) DEFAULT NULL, `time` varchar(100) DEFAULT NULL, `request` varchar(100) DEFAULT NULL, `status` varchar(100) DEFAULT NULL, `body_bytes_sent` varchar(100) DEFAULT NULL, `http_referer` varchar(100) DEFAULT NULL, `http_user_agent` varchar(100) DEFAULT NULL, `http_x_forwarded_for` varchar(100) DEFAULT NULL, `time_local` text, `datetime` text, `host` text, `program` text, `pid` text, `message` text ) ENGINE=InnoDB DEFAULT CHARSET=latin1 Now first thing that goes wrong is when I restart syslog-ng: # /etc/init.d/syslog-ng restart Stopping syslog-ng: [ OK ] Starting syslog-ng: WARNING: You are using the default values for columns(), indexes() or values(), please specify these explicitly as the default will be dropped in the future; [ OK ] I have tried creating a file destination and it all works fine, and then I have tried replacing my destination with: destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("kosmodromas") database("syslog") table("nginx") columns("datetime", "host", "program", "pid", "message") values("$R_DATE", "$HOST", "$PROGRAM", "$PID", "$MSGONLY") indexes("datetime", "host", "program", "pid", "message")); }; Which did work and it was writing stuff to mysql, The problem is that I want to write stuff to in exact format as nginx log format is. I assume that I am missing something really simple or I need to do some parsing between source and destination. Any help will be much appreciated :)

  • IPSec VPN using ZyWALL IPSec VPN Client: unable to connect from some providers

What could I check? Where could be the problem ?

  • Is is possible to guide installation of new programs using %ProgramFiles%? [closed]

    - by ??????? ???????????
    The purpose of this is to have the default "program files" (32 and 64 bit) folders located under an arbitrary path, possibly on a drive separate from where windows lives. Initially I thought that this may be done using a system environment variable through the dialog located under Control Panel - System - Advanced - Environment Variables. These variables turned out to be set in the registry under the key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion. However, one particular entry is confusing. The ProgramFilesPath entry seems to point at an environment variable that is not defined under the same registry key. I could assume that the difference between ProgramFilesDir and ProgramFilesPath is none and that one of them exists as a backwards compatibility, but having some legitimate resource from Microsoft to look at would be better than guessing. After receiving some worrying feedback about having both 32 and 64bit applications in the same folder, I have decided not to ask about the feasibility of this to avoid discussion. The real question is if the desired effect is possible to attain by "cutting into" the windows setup process and modifying those registry entries as early as possible. These settings should be system wide and not only for software installed by a particular user. If this is indeed something that can be done, I wonder if there are any subtle pitfalls. Programs that expect libraries and other resources to be in default locations can probably be dealt with using the same technique as employed by Windows to re-map the "Documents and Settings" folders and the like (i.e. breaking legacy applications is not real concern).

  • For simple C cmd programs: how to add "program executed in 12,345 seconds" ?

    - by WoodsieLord
    I'm a windows user, and I'm learning C. I use Codeblocks and visual c++ 2008 express at home to write simple C command line programs (I'm a beginner) and I find really useful when codeblocks adds a few lines at the end with the time it takes (example: "Process returned 0 (0x0) execution time : 6.848 s"). I want to add this functionality to the .exe so I can 'benchmark' or 'test' the program on a few computers. I tried using time(NULL) but it only works with 1 second precision. I also found very interesting answers here (I'm actually looking for the same thing): http://stackoverflow.com/questions/2173323/calculating-time-by-the-c-code The solution proposed by Mark Wilkins, works fine on visual c++ 2008 express on my windows 64 bit PC, but the .exe does not work anywhere else. Am I doing something wrong? I would like a method to count elapsed wall time for my programs, that must have 32bit compatibility. Thanks in advance!

  • How Two Programs Can Talk To Each Other In Java?

    - by Arnon
    My first time here... I want to ?reduce? the CPU usage/ROM usage/RAM usage - in general ?speaking?, all system resources that my App use - how doesn't? :) For this reason i want to split the preferences window from the rest of the application, and let the preferences window to run as ?independent? program. The preferences program ?should? write to a Property file(not a problem at all) and to send a "update signal" to the main program - which mean, to call the update method(that i wrote) that found in the Main class. How can i call the update method in the Main program from the preferences program? Or in the other hand... There is a way to build preferences window that take system resources just when it's appear? Is this approach - of separating programs and let them talk to each other(somehow) - is a right approach for speeding up my programs? tnx

  • Using scanf() in C++ programs is faster than using cin ?

    - by zeroDivisible
    Hello, I don't know if this is true, but when I was reading FAQ on one of the problem providing sites, I found something, that poke my attention: Check your input/output methods. In C++, using cin and cout is too slow. Use these, and you will guarantee not being able to solve any problem with a decent amount of input or output. Use printf and scanf instead. Can someone please clarify this? Is really using scanf() in C++ programs faster than using cin something ? If yes, that is it a good practice to use it in C++ programs? I thought that it was C specific, though I am just learning C++...

    Hi, I have a dvd with some family photos that is scratched, the problem is that when i try to copy stuff it reaches certain points and freezes, i'm assuming its the scratches / corrupt data. I've been trying several programs that are supposed to copy corrupt files from damaged media regardless, but they keep freezing when they reach the same points, so no different when with windows. Is there a way to fix the DVD? Or a really really good program that can do that without freezing / allowing windows to freeze? Please help, I don't have any copies of the photos and they are irreplaceable.

  • Default shell for running scripts (w/o shebang) in macos?

    - by Igor Spasic
    I have ZSH as default shell in MacOS, everything is working fine. ZSH is installed as brew package, Ive set default shell in my account, new shell is listed in /etc/shells... everything is set, like I've said. I have some shell scripts in which I use some commands from zsh, like print. When I execute the script from command line, the print command is not recognized and the script fails. This script does not have the shebang line. When I put the shebang line for zsh, then everything works; the print command is working. Since I am using only ZSH, is it possible to set default shell for running scripts, so I don't have to put shebang line in my .zsh scripts? Or is it possible to associate .zsh extension to ZSH shell execution?
