• JTable filled with database data is not being updated when columns are reordered.

  - by marionmaiden

  I have a JTable filled with data of a table of my database (so I used ResultSetTableModel) and using TableRowSorter to sort the rows, as I click in one column of the JTable. The data is displayed in the jTable without problems; But when I sort the JTable by some column table (for example, sorting it by the primary key value), and edit some cell from the sorted jTable, the value changed is the old cell that were in that position before the ordenation of the column. For example: Suppose I have a table with 2 columns - name and age. My table has the following data: c 1 b 2 a 3 when I order i by name in the JTable, it becomes like this a 3 b 2 c 1 if I edit the value "1", after the edition, the table becomes like this a 1 b 2 c 1 It seems that the positions are not being updated in the JTable, and the values are edited considering their original positions.

• Shared printer hosted by Windows 7 to XP peers [closed]

  - by Alistair Knock

  Possible Duplicate: Add Network Printer drivers in Windows 7/Server 2008 R2? A Canon Pixma ip4600 installed all by itself when connected to a Windows 7-64 bit machine. I then updated it with the add-on Canon provide to give additional functionality. I then wish to share it with a box which is running Windows XP 32-bit. The XP box can see the printer but can't find a driver from the 7 machine, which is fine. I ask the 7 machine to get the x86 drivers, but it can't. I install the 32-bit XP drivers on the XP machine, but unlike previous Canon drivers (which unzip to give an .inf file), they assume a local printer and partially give up. I find the .inf file in the Program files\CanonBJ\... directory. Neither the XP machine, nor the 7 machine when the CanonBJ directory is shared to it, is happy with the .inf file. I attempt to install the 32-bit drivers on the 64-bit 7 machine, which, understandably, fail. Where do we go from here? (I apologise for posting in the first-person, I'm not sure why this was)

• jQuery autocomplete function, how to add support for words not available in the database yet?

  - by Lyon

  Hi, I'm looking to implement a tag system like how SO uses on their site, where users can specify multiple tag words. However, on top of all the other autocomplete functions available as jquery plugins, I also want to allow users to enter new words not in the database. Does anyone know of any plugin that can do that? Or if there isn't, how one can add that functionality to an existing autocomplete function? I'm exploring Drew Wilson's autosuggest plugin at the moment, as it supports multiple tags well: http://code.drewwilson.com/entry/autosuggest-jquery-plugin Any help appreciated! Thanks :)

• How do you get the glyph for a character encoded as '&#333;' from a utf-8 encoded database field usi

  - by AE

  I have a MySQL database table with a collation of 'utf8_general_ci' and the value in the field is: x & #299; bán yá wén (without the spaces). When this is converted (for example by StackOverflow's editor) it looks like this: xī bán yá wén where the second character looks like a lower case i with a bar over the top. In PHP, what function converts the & #299 ; entity into the ī character? I've tried using html_entity_decode($str,ENT_COMPAT,'UTF-8'), however I get characters like the following: yÄ«n wén or zhÅ•ng wén I'm pretty sure there's something I don't understand about the decoding, which is why I'm using the wrong function. Can anyone shed some light on how to get the single character glyph that's represented by the entity & #299 and similar high-number characters above 255? Many thanks, AE

• SqlLite/Fluent NHibernate integration test harness initialization not repeatable after large data se

  - by Mark Rogers

  In one of my main data integration test harnesses I create and use Fluent NHibernate's SingleConnectionSessionSourceForSQLiteInMemoryTesting, to get a fresh session for each test. After each test, I close the connection, session, and session factory, and throw out the nested StructureMap container they came from. This works for almost any simple data integration test I can think, including ones that utilize Fluent NHib's PersistenceSpecification object. When I test the application's lengthy database bootstrapping process, which creates and saves thousands of domain objects, I start seeing issues. It's not that the setup and tear down fails, in fact, the test successfully bootstraps the in-memory database as the application would bootstrap the real database in the production environment. The problem occurs when the database bootstrapping occurs a second time on a new in-memory database, with a new session and session factory. The error is: NHibernate.StaleStateException : Unexpected row count: 0; expected: 1 The row count is indeed Unexpected, the row that the application under test is looking for should be in the session. You see, it's not that any data from the last integration test is sticking around, it's that for some reason the session just stops working mid-database-boostrap. And I've looked everywhere for a place I might be holding on to an old session and I can't find one. I've searched through the code for static singleton objects, but there are none anywhere near the code in question. I have a couple StructureMap InstanceScope singleton's but they are getting thrown out with each nested container that is lost after every test teardown. I've tried every possible variation on disposing and closing every object involved with each test teardown and it still fails on this lengthy database bootstrap. But non-bootstrap related database tests appear to work fine. I'm starting to run out of options and may have to surrender lengthy database integration tests in favor of WatiN-based acceptance tests. Can anyone give me any clue about how I can figure out why some of my SingleConnectionSessionSourceForSQLiteInMemoryTesting aren't repeatable? Any advice at all, about how to make an NHibernate SqlLite database integration test harness repeatable?

• How can I prevent Firefox from storing a 10 MB places database file in my Windows roaming profile?

  - by Paul D. Waite

  On my work PC, Firefox stores a 10 MB file called places.sqlite in my roaming profile: C:\Users\MY_USERNAME\AppData\Roaming\Mozilla\Firefox\Profiles\PROFILE_ID\places.sqlite I don't use any location-related features in Firefox, and this file causes my roaming profile to be larger than my company allows (25 MB), meaning I get warnings about my profile size every day. Can I stop Firefox storing this file in my roaming profile?

• Detecting a Dispose() from an exception inside using block

  - by Augusto Radtke

  I have the following code in my application: using (var database = new Database()) { var poll = // Some database query code. foreach (Question question in poll.Questions) { foreach (Answer answer in question.Answers) { database.Remove(answer); } // This is a sample line that simulate an error. throw new Exception("deu pau"); database.Remove(question); } database.Remove(poll); } This code triggers the Database class Dispose() method as usual, and this method automatically commits the transaction to the database, but this leaves my database in an inconsistent state as the answers are erased but the question and the poll are not. There is any way that I can detect in the Dispose() method that it being called because of an exception instead of regular end of the closing block, so I can automate the rollback? I don´t want to manually add a try ... catch block, my objective is to use the using block as a logical safe transaction manager, so it commits to the database if the execution was clean or rollbacks if any exception occured. Do you have some thoughts on that?

• Would a Socket Connection Outperform an Intarvaled Database Sweep and Requests?

  - by Jascha

  I'm building a small chat application to add to an existing framework. There will only be 20-50 users MAX at any one time. I was wondering if I could get away with updating a cache file containing (semi) live chat data for whichever users happen to be chatting just by performing timed queries and regular AJAX refreshes for new data as opposed to learning how to open and maintain a socket connection. I'm sure there are existing chat plug-ins out there. But I just had a hell of a time installing one and I could see building the whole damn thing taking just as much time as plugging one in. Am I off to a bad start? Thanks in advance -J (p.s. this is a semi closed network behind a php login so security isn't a great concern)

• Is there an alias for the local machine name in the Windows 7 login screen?

  - by Mikael

  We have many computers connected to a AD. The computers names is auto generated. When I want to log in using a local account, I have to figure out what the computer's name is, and log in using the following syntax: [COMPUTER_NAME]\local_account Now I'm wondering if there is an alias that I can use instead? So instead of logging in using NB-aw35sdds\local_account, I can use something like localhost\local_account.

• thoughs on using Alpha Five v10 with Codeless AJAX for building an AJAX database app in a short amou

  - by william Hunter

  I need to build an AJAX application against our MS SQL Server database for my company. the app has to have user permissions and reporting and is pretty complex. I am really under the gun in terms of time. The company that I work for needs the app for an important project launch. A colleague/friend of mine in a different company recommended that I look at a product from Alpha Software called Alpha Five v10 with Codeless AJAX. He has told me that he has used it extensively and that it saves him a "serious boat load of time" and he says that he has not run into limitations because you can also write your own JavaScript or you wire in JQERY. Before I commit to Alpha Five v10, I would like to get any other opinions? Thanks. Norman Stern. Chicago

• How do I improve my screen resolution in Windows Remote Desktop?

  - by Jeff

  I'm RDP'ing into a Win2K3 machine from a WinXP machine, and I cannot stand the low screen resolution I get on the Win2K3 box. Text is too large and the graphics/colors aren't very smooth. How do I improve this? If I right-click on the desktop of the remote machine and go to Properties - Settings, I see that the screen resolution is set to 1280x1024 (should be okay, I would think), and the color quality is Medium (16 bit) (not optimal) and I don't have the option to change either setting (because they're set in the .rdp file for the session, right?). If I move over to the Appearance tab, I see that font size is set to Normal, with no option to make it smaller. The thing is, these settings are close to what I have on the XP machine I'm RDP'ing in from. The only difference (in those settings) is the color quality, which is 32 bit. Any ideas on how I can improve the situation? Other tidbits: The graphics card on the Win2K3 machine is ATI ES1000. I think I have the latest drivers for it. I'm running VMware Workstation on the Win2K3 machine, and if I create a Win2K3 VM and RDP into it from the XP machine, the resolution is just fine.

• How to use HSQLDB in Oracle query syntax mode?

  - by Jan Algermissen

  I am trying to use HSQLDB as an embedded database in a spring application (for testing). As the target production database is Oracle, I would like to use HSQLDBs Oracle syntax mode feature. In the Spring config I use <jdbc:embedded-database type="HSQL" id="dataSource"> </jdbc:embedded-database> <jdbc:initialize-database data-source="dataSource" enabled="true"> <jdbc:script location="classpath:schema.sql"/> </jdbc:initialize-database> And in schema.sql at the top I wrote: SET DATABASE SQL SYNTAX ORA TRUE; However, when running my test, I get the following error: java.sql.SQLException: Unexpected token: DATABASE in statement [SET DATABASE SQL SYNTAX ORA TRUE] Is this a syntax error or a permissions error or something entirely different? Thanks - also for any pointers that might lead to the answer. Given that HSQL is the Spring default for jdbc:embedded-database and given the target is Oracle, this scenario should actually be very common. However, I found nothing on the Web even touching the issue.

  I have a small network in which there are 2 electronic devices and one desktop connected using a switch. Through the desktop with Ethereal/wireshark installed on it, can I sniff the packets that are being communicated between the 2 electronic devices? I cannot install ethereal or wireshark on either of the electronic devices, but need to monitor the traffic between the 2 devices from my desktop, which is connected via the same switch.

• How do I limit the permissions of a C# program to read only on an SQLServer Database?

  - by gav

  Hi Guys, I have written some C# which connects to a live production database. I want to give my application read only access to the DB but am unsure how to achieve this. Is there any trivial way to get this done by amending the connection string? My understanding is that the application will logon with the credentials of the person running the application and hence may or may not have write access to the db based on that fact. Can I statically limit the permissions of the application so that if someone changes the program to do something devastating at a later date any manipulation will fail? Apologies for how trivial the question may be but it's my first venture into the world of MS programming. Thanks, Gav

• Pair programming with tmux and Vagrant

  - by neezer

  Does anyone have a clear step-by-step guide for setting up a shared tmux session on a Vagrant vbox that my coworkers (on our local office lan) could SSH into? The articles I've found online only seem to cover setting this up from machine to machine (no virtualbox setups), and I'm not very good at networking, so I haven't been able to extrapolate a solution... We're all running the latest Macs in our office, btw. Here's one article I've found but haven't been able to get working with Vagrant: http://blog.voxdolo.me/remote-pairing-with-vim-and-tmux.html EDIT: To clarify, I don't really know how I should be setting up Vagrant to allow me to SSH into it from a machine outside the one hosting the VM. The article above suggests that I add the tunnels host on my physical machine running the VM (here-on referred to as the MBP), so I did that. Next is the ProxyCommand host declaration, which I have also assumed should live on the MBP. So next I try SSHing into the MBP from a guest machine (another separate physical machine on my network), and that seems to work... but that only gets me into the MBP, not the Vagrant image running on the MBP. I normally login Vagrant image on the MBP via vagrant ssh (per the docs), and I know how to forward ports on the Vagrant VM to the MBP, but it's unclear to me how I could forward ports/SSH from the MBP to the Vagrant VM, which I assume I would need to do so that my guest machine could SSH in--through the MBP--to my Vagrant image. That, in a nutshell, is what I'm trying to accomplish. I do my development work in Vagrant VMs which keeps my MBP nice and clean of any dev-related cruft and also keeps my dev environments totally isolated from one another, yet I would like to start pair-programming with my coworkers via tmux, thus the reason why I've asked this question. I would like to accomplish all of this without setting up an additional user account on the MBP, or giving my coworkers access to my local user account on the MBP to get to my Vagrant VM, if that's at all possible.

• How do I maintain formatting of comments when I save them to the database in an asp.net mvc applicat

  - by baijajusav

  The title was probably not very clear. Consider this scnerio: you have a blog site or really just any site where a user can respond via a comment. You want to maintain the formatting for the comments. So paragraph's should be separated, first sentence indented, bolding of keywords allowed, etc. How would one go about doing this? This is something just about every kind of blogging site handles, including this site. My initial guess is that comments are saved to that database either in an xml format or as the raw html. Those are really my only guesses. I suppose magic strings could be used to denote the starting and ending of various formatting as well, but magic strings are generally frowned upon. I'm doing this in an asp.net mvc application. I'm using version 1 of mvc, but I would be willing to move to 2 if that makes for an easy solution here.

• Windows 7 - system error 5 problem

  - by ianhobson

  My wife has just had a new computer for Christmas (with an upgrade from VISTA to Windows 7), and has joined the home network. We are using a mix of WindowsXP and Ubuntu boxes linked via a switch. We are all in the same workgroup. (No domain). Internet access, DHCP, and DNS server is an SME server that thinks it is domain controller (although we are not using a domain). I need to run a script to back up my wife's machine (venus). In the past the script creates a share on a machine with lots of space (leda), and then executes the line. PSEXEC \\venus -u admin -p adminpassword -c -f d:\Progs\snapshot.exe C: \\leda\Venus\C-drive.SNA With the wife's old XP machine, this would run the sysinternals utility, copy shapshot,exe to her machine and run it, which would then back up her C: drive to the share on leda. I cannot get this to work with Windows 7, nor can I link through to the C$ share on her machine. This gives me a permissions error (system error 5). The admin account is a full admin account. And yes - I do know the password. The ordinary shares on her machine work fine! I guess I'm missing something that Microsoft have built into Windows 7 - but what? The machine is running Windows 7 business, with windows firewall, AVG anti virus, and all the crap-ware you get with a new PC removed. Thanks

• python os.execvp() trying to display mysql tables gives 1049 error - Unknown database error.

  I have a question related to mysql and python. This command works on the shell, but not when I use os.execvp() $./mysql -D test -e "show tables" +----------------+ | Tables_in_test | +----------------+ | sample | +----------------+ The corresponding piece of code in python would be def execute(): args = [] args.extend(sys.argv[1:]) args.extend([MYSQL, '-D test -e "show tables"']) print args os.execvp(args[0], args) child_pid = os.fork() if child_pid == 0: os.execvp(args[0], args) else: os.wait() The output of this is: [./mysql', '-D test -e "show tables"'] ERROR 1049 (42000): Unknown database ' test -e "show tables"' I am not sure if this is a problem with the python syntax or not. Also, the same command works with os.system() call. os.system(MYSQL + ' -D test -e "show tables"') Please let me know how to get this working. Thanks, Hemanth

• Are there any tools to help the user to design a State Machine to be consumed by my application?

  - by kolrie

  When reading this question I remembered there was something I have been researching for a while now and I though Stackoverflow could be of help. I have created a framework that handles applications as state machines. Currently all the state business logic and transactions are handled via Java code. I was looking for some UI implementation that would allow the user to draw the state machines and transactions and generate a file that can later on be consumed by my framework to "run" the workflow according to one or more defined state machines. Ideally I would like to use an open standard like SCXML. The goal as the UI would be to have something like this plugin IBM have for Rational Software Architect: Do you know any editor, plugin or library that would have something similar or at least serve as a good starting point?
