• Oracle: '= ANY()' vs. 'IN ()'

  - by eidylon

  Hi all, I just stumbled upon something in ORACLE SQL (not sure if it's in others), that I am curious about. I am asking here as a wiki, since it's hard to try to search symbols in google... I just found that when checking a value against a set of values you can do WHERE x = ANY (a, b, c) As opposed to the usual WHERE x IN (a, b, c) So I'm curious, what is the reasoning for these two syntaxes? Is one standard and one some oddball Oracle syntax? Or are they both standard? And is there a preference of one over the other for performance reasons, or ? Just curious what anyone can tell me about that '= ANY' syntax. CheerZ!

• Best Practice Guide: Swing

  - by wishi_

  Hi! Does anybody know Swing related GUI guidelines - specifically on how to design Swing apps and which components I should use? I'm not looking for an official standard, but pragmatic tips I can use to set a good standard for my projects. I haven't used too much of Swing by myself. Surely clicking a GUI with a GUI designer isn't a big deal. However I'd like to get some insights from people who have experience with Swing and know what to avoid. Swing lately (in Java 6- 10) got decent changes. So there isn't too much specific standardization out there currently.

• Zip up web page groups to view in browsers

  - by Arlen Beiler

  There should be a standard for saving viewing bunches of webpages as a website. For instance, say I have a whole bunch of pages, such as I get from the WordPress plugin "Really Static" which saves an entire site, and I have all the links start with a slash. Now, I can't really use those links if I am reading it from the file system. If there would be a standard where we could zip up files, give them a unique extension (like "hzip" for html zip), and open the file with any browser, which would display it as though the root of that file were the root of the pages. "http://example.com" The links would all work right. This would facilitate sharing and copying groups of webpages.

• How do you implement caching in Linq to SQL?

  - by Glenn Slaven

  We've just started using LINQ to SQL at work for our DAL & we haven't really come up with a standard for out caching model. Previously we had being using a base 'DAL' class that implemented a cache manager property that all our DAL classes inherited from, but now we don't have that. I'm wondering if anyone has come up with a 'standard' approach to caching LINQ to SQL results? We're working in a web environment (IIS) if that makes a difference. I know this may well end up being a subjective question, but I still think the info would be valuable. EDIT: To clarify, I'm not talking about caching an individual result, I'm after more of an architecture solution, as in how do you set up caching so that all your link methods use the same caching architecture.

• How to recognize whether a web site is opened in a mobile or a PC

  - by Yogi Yang 007

  We have a site developed in PHP. It is working just fine. We have used JQuery for every kind of situation like slide shows, menus, etc. This site contains a lot of images which are large in size. because of this when viewed in a mobile phone user has to scroll a lot. How can we recognize whether the client (browser) trying to access our site is a mobile phone or a standard PC. Is there any standard way to build site for such situations? TIA

• How to automate photoshop from the command line.

  - by Raymond

  I have a tool which writes some tags to a photo. On some photos it fails, and for those I want to open them in photoshop, and resave it with maximum quality (jpeg). Ideally I would like to do that from the command line as then I can just do: for %a in (*.jpg) do mytool.exe "%a" || [AUTOMATED PROCESS HERE] I tried first just doing photoshop.exe "%a" but it seems photoshop doesn't even accept a command line argument for what photo to open.

• abandon session in asp.net on browser close..kill session cookie

  - by Tuviah

  So I have a website where I use session start and end events to track and limit open instances of our web application, even on the same computer. On page unload i call a session enabled page method which then called session.abandon. This triggers session end event and clears the session variable but unfortunately does not kill the session cookie!! as a result if other browser instances are open there are problems because their session state just disappeared...and much worse than this when I open the site again with the zombie session still not expired, I get multiple session start and session end events on any subsequent postbacks. This happens on all browsers. so how do I truly kill the session (force the cookie to expire)

• Problems with XAML WPF 4.0 Editor in VS2010

  - by RTPeat

  Wondering if anybody else has found some very odd behaviour with the XAML/WPF 4 editor in VS2010. This only occurs if the project is using .NET 4. Whenever I tried to open a XAML document for editing, the window would appear to open for a split second and then vanish, but VS2010 would still list the window as open. The fault was eventually traced to having the "Reuse current document window, if saved" option under "Documents" in the "Environment" options checked. Once this was unchecked XAML 4 files opened as expected. As I said, this only appears to occur on projects targeted at .NET Framework 4 - those targeted at 3.5 worked without a problem, and the "Reuse current document window, if saved" appears to work fine on other files.

• sqlcipher command line not working

  - by Min Lin

  I have a encrypted sqlite db and its key. (Which is generated by an android program). However, when I open the db in command line I can not read the db. The command line tool is installed by: brew install sqlcipher I open the database by: sqlcipher EnDB.db >pragma key="6b74fcd"; >select * from bizinfo; It keeps telling me "Error: file is encrypted or is not a database" However, if I open the database file with gui app sqlite database browser (which is a windows program and I run it in wine). It pops up a window for me to enter the key, with 6b74fcd as the key it successfully read the database. As I want to automatically process the db in the future, I can not depend on the GUI. Do you know why the command line is not working?

• Handling newline character in input between Windows and Linux

  - by Fazal

  I think this is a standard problem which may have been asked before but I could not get the exact answer so posting the issue. The issue is that our server is running on a linux box. We access the server over the browser on a window box to enter data into field which is supposed to contain multiple lines which user can enter by pressing the enter key after each line Abc Def GHI When this input field (this is a text area),is read on the linux machine, we want to split the data based on new line character. I had three question on this. Does the incoming data contain "\r\n" or "\n" If incoming data does contain "\r\n", the linux line.separator property (vm property) would not work for me as it would say "\n" and therefore may leave "\r" in the data. If "\r" is left in the data, if I open the file on a windows machine, will this mean a newline character? Finally can anyone tell me the standard way to deal with this issue?

• I need to set-up the blocked machine to relay to the unblocked machine using a different port

  - by Zain Ally

  I have two Windows Server 2003 machines sitting in a network. Server B has port 25 open and can relay emails to the local network's smtp server. Server A does not have port 25 open. How can I set it up to send emails through another port to the SMTP server? I am thinking if I can setup a local SMTP communication between my servers on a different port and let Server B send Server A's emails. Is that possible?

• Reset form with jQuery

  - by da5id

  I have a form with a standard reset button coded thusly: <input type="reset" class="button standard" value="Clear" /> Trouble is, said form is of the multi-stage sort, so if a user fills out a stage & then returns later, the 'remembered' values for the various fields won't reset when the Clear button is clicked. I'm thinking that attaching a jQuery function to loop over all the fields and clear them 'manually' would do the trick. I'm already using jQuery within the form, but am only just getting up to speed & so am not sure how to go about this, other than individually referencing each field by ID, which doesn't seem very efficient. TIA for any help.

• Autoconf macros for Apache and conf.d install process?

  - by Stephen Burke

  I have a package that is using the autotools to build and install. Part of the package is a website that can be run on the local machine. So in the package there is a .conf file that is meant to be either copied or linked to the /etc/apache2/conf.d directory. What's the standard way that packages would do this? If possible, I'd like for the user not to have an extra step to make the website work. I'd like to have them install the package and then be able to browse to http://localhost/newpackage to get up and running. Also, is there a way that autoconf knows about the apache install or a standard way through then environment some how? If someone could point me in the right direction that would be great. Steve

• Grand Central Strategy for Opening Multiple Files

  - by user276632

  I have a working implementation using Grand Central dispatch queues that (1) opens a file and computes an OpenSSL DSA hash on "queue1", (2) writing out the hash to a new "side car" file for later verification on "queue2". I would like to open multiple files at the same time, but based on some logic that doesn't "choke" the OS by having 100s of files open and exceeding the hard drive's sustainable output. Photo browsing applications such as iPhoto or Aperture seem to open multiple files and display them, so I'm assuming this can be done. I'm assuming the biggest limitation will be disk I/O, as the application can (in theory) read and write multiple files simultaneously. Any suggestions? TIA

• Convert any currency string to double

  - by James

  I need to store multiple currencies in SQL server. I understand that SQL won't support all different types of currencies (unless I store it as a string, but I don't want to do that). My idea was to convert all the values from their currency format to a standard double and store that instead. Then just re-format based on the culture info when displaying. However, I have tried doing something like e.g. var cultureInfo = new System.Globalization.CultureInfo("en-US"); double plain = return Double.Parse("$20,000.00", cultureInfo); This doesn't ever seem to work it always throws a FormatException. Even removing the currency symbol and just trying to do this based on the number alone does the same thing. This is just an example I want to support pretty much any type of currency. Is there a standard way of stripping out currency and getting the value as a double?

• Comcast SMC Port Forwarding Issue

  - by Zach Fedora

  I have a Comcast SMCD3G modem/router and I've been having issues getting the port to forward - When I check an online "open-port-checker" it says the port is forwarded/they can see the port on my IP. (1 Static IP is assigned to the modem) But when I try to access port 80 for example on a browser, it times out. Also when I try to remote desktop to the server (Windows Server 2008 R2) it doesn't work, yet canyouseeme.org says it is open. Any ideas as to what the problem could be?

• How to catch 'exceptions' for out of order execution in Workflow Foundation 4?

  - by Alex Key

  Hi, I am attempting to model a worklfow using a "WCF Workflow Service" in .net / vs 2010 that needs to handle out of order execution gracefully (but not allow it - if thath makes sense!?) For example I have 2 receive activities one called Initialize and the other called GetValue inside a FlowChart. In most cases Initialize should be called first and GetValue after (as modled in the flow chart). However if GetValue is executed before Initialize I do not want to return an "out of order" exception (although when I look at the WCF test client, I can't actually see an exception). But instead a custom exception saying something like "you must initialize first". In theory I could model this with lots of parallel activities and conditions to check if Initialized / Running / Terminated etc. But the business process I am modelling if very very similar to a state machine... except it must handle people executing things in the wrong order. Ideally I would like to catch the "out of order" exception (thought I don't think it's really an exception as such), check the 'exception' to see which function was attempted to run and then handle it. I have done some research around enabling AllowBufferedReceive. However I don't want to be able to execute out of order (I don't think), but instead give a detailed response if it does happen. I've looked at the new beta state machine template for WF 4 - but i'm not sure if it does what i'm after? I'm not sure if I have the wrong end of the stick, so any help would be greatly appreciated. [EDIT] To help clarify... Sorry it's a tricky one to explain. The standard I am trying to implement (the e-learning standard SCORM RTE) is structured like a state machine i.e. certain functions can only be executed in certain states. However the standard specifies that if the calling clients tries to execute a function that it is not meant to, then a warning should be issued... for example "you cannot use GetValue(), because you have not yet Initialized". Ideally I'd like to structure the workflow as the theoretical state machine and not need to have to use multiple if/else's to handle all the scenarios where something could be executed out-of-order. I'd like to catch a out-of-order exception (but I don't think there is such an exception - as it's not in the debugger) and rethrow it.

• Seeking a GUI auto-format feature for T-SQL

  - by dvanaria

  Is there a freely available GUI tool that will allow interaction with Microsoft SQL Server (via T-SQL) that provides an auto-format feature? I constantly find myself writing queries in SQL Query Analyzer (Microsoft’s standard GUI tool for T-SQL) and cutting/pasting the whole thing into SQLyog (a GUI tool for MySQL), where I can press F12 and have it reformatted into an easily readable, industry standard format. I then cut/paste this back into Query Analyzer to execute. I do this all the time at work and haven’t been able to find an alternative. I realize that SQLyog is no longer free software, but what I’m looking for is a specific alternative to a MS SQL Server interface (with auto-formatting). Thanks in advance for your help.
