• WindowStartupLocation.CenterScreen is opening my window on the wrong display

  - by chaiguy

  According to the documentation, CenterScreen should open the window in the center of the screen that contains the mouse cursor, however this is not happening. I have a dual monitor setup, with my secondary monitor appearing to the left of my primary monitor (the one with the task bar). When the user clicks a link in my interface on the primary (right-most) monitor, and I open a new window with WindowStartupLocation set to CenterScreen, the window appears in the center of the screen of the left monitor. This is not where the mouse is and I am lost as to why it is picking that display. Has anyone experienced this before or have any ideas for a workaround? If I can't get the proper behavior using WindowStartupLocation, I will just manually move the window to the proper display (I still have to figure that out though).

• How to play multiple online videos on IOS continuously

  - by Matt.Z

  The scenario is like this: I have some long video, and slice it into small files(mp4, for example: 5 min per file), put them under some website. I wanna play (on IOS) these mp4 videos continuously, one by one, try to do not let user feel there has a pause between video pieces. So I need to buffer next video when I play current one. But I don't know where to start. What should I do? Can anyone give me some information of related documentation or source code I can study with?

• Wordpress API: Add / Remove Tags on Posts

  - by st4ck0v3rfl0w

  I know it seems like a simple operation, but I can't find any resource or documentation that explains how to programmatically add and remove tags to a post using the post ID. Below is a sample of what I'm using, but it seems to overwrite all the other tags... function addTerm($id, $tax, $term) { $term_id = is_term($term); $term_id = intval($term_id); if (!$term_id) { $term_id = wp_insert_term($term, $tax); $term_id = $term_id['term_id']; $term_id = intval($term_id); } $result = wp_set_object_terms($id, array($term_id), $tax, FALSE); return $result; }

• Sqlalchemy layout with WSGI application

  - by TheDude

  I'm working on writing a small WSGI application using Bottle and SqlAlchemy and am confused on how the "layout" of my application should be in terms of SqlAlchemy. My confusion is with creating engines and sessions. My understanding is that I should only create one engine with the 'create_engine' method. Should I be creating an engine instance in the global namespace in some sort of singleton pattern and creating sessions based off of it? How have you done this in your projects? Any insight would be appreciated. The examples in the documentation dont seem to make this entirely clear (unless I'm missing something obvious). Any thoughts?

• PHP 5.4 turn display_errors off php.ini

  - by Ethan H

  I need PHP errors not to be displayed but logged. I am using PHP 5.4 My current code to log errors in my php.ini is: log_errors = 1 error_log = "/path-to-file/error_log.txt" Which works however I am getting a 500 internal server error trying to turn error displaying off using display_errors. I have tried using the following, all returning 500 errors. display_errors = 0 display_errors = "0" display_errors = false display_errors = "false" display_errors = Off display_errors = "Off" According to the PHP documentation, as of PHP 5.4, it is a string. What am I suppose to set display_errors to to turn error displaying off?

• How to do "See Also" to a book using doxygen

  - by Paul J. Lucas

  The Javadoc @see allows a simple string as an argument to refer to something like a book, e.g.: @see "The Java Programming Language." As far as I can tell, the Doxygen \see offers no equivalent. Is there any way to have a book reference generated in the documentation, e.g.: See Also The C++ Programming Language, Bjarne Stroustrup, Addison-Wesley, 2000, section 19.4.1: The Standard Allocator ? Clarification This question is about how to do a "See Also" as part of a comment, e.g.: /** * Allocates memory in an amazing way. * \param size The number of bytes to allocate. * \return Returns a pointer to the start of the allocated memory. * \see MyOtherClass::alloc() * \see "The C++ Programming Language," Bjarne Stroustrup, Addison-Wesley, 2000, * section 19.4.1: The Standard Allocator. */ void* my_alloc( size_t size ); Of course the above does not work in Doxygen. Note that if there are multiple \see tags, they should be merged into a single "See Also" section (like the way \see normally works.

• iPhone: Setup static content of UITableView

  - by Martin

  This guide from apple https://developer.apple.com/iphone/prerelease/library/documentation/UserExperience/Conceptual/TableView_iPhone/TableViewCells/TableViewCells.html (you need login) explains how to use "The Technique for Static Row Content" to use Interface Builder to setup the cells in a tableview. I have some cells with different heights in my tableview. Without using the heightForRowAtIndexPath method everything get messed up. Do I still need to use this method or can I in some way setup the height of the cells inside the IB as I created them there? Also when using the "The Technique for Static Row Content" from the guide you still need to use the cellForRowAtIndexPath to setup the cells even if they are created in IB. I would like to setup the full layout of the tableview with all cells in IB (drag the cells right into the tableview), is that possible in some way? Thanks!

• customising serialisation of java collections using xstream

  - by Will Goring

  I have an object that needs to be serialised as XML, which contains the following field: List<String> tags = new List<String>(); XStream serialises it just fine (after some aliases) like this: <tags> <string>tagOne</string> <string>tagTwo</string> <string>tagThree</string> <string>tagFour</string> </tags> That's OK as far as it goes, but I'd like to be able to rename the <string> elements to, say, <tag>. I can't see an obvious way to do that from the alias documentation on the XStream site. Am I missing something obvious?

• C# testing framework that works like JUnit in Eclipse?

  - by bluebomber357

  Hello all, I come from a Java/Eclipse background and I fear that I am spoiled by how easy it is to get JUnit and JMock running in Eclipse, and have that GUI with the bar and pass/fail information pop up. It just works with no hassle. I see a lot of great options for testing in C# with Visual Studio. NUnit looks really nice because it contains unit and mock testing all in one. The trouble is, I can't figure out how to get the IDE display my results. The NUnit documentation seems to show that it doesn't automatically show results through the VS IDE. I found http://testdriven.net/, which seems to trumpet that is makes VS display these stats and work with multiple frameworks, but it isn't open source. Is there anyway to get unit and mock testing working with the VS IDE like it does in Java with Eclipse?

• Subversion pre-commit hook to clean XML from WebDAV autocommit client

  - by rjmunro

  I know that it isn't normally safe to modify a commit from a pre-commit hook in Subversion because SVN clients will not see the version that has been committed, and will cache the wrong thing, but I'd like to clean the code from a versioning-naïve WebDAV client that won't keep a local cached copy. The idea is that when I look at the repository with an SVN client, the diffs are clean. The client, by the way is MS Word, using 2003 XML format files. We're already using this format in a WebDAV system, but we'd like to add a versioning capability for expert users. Everywhere I look for documentation on how to modify the code in a pre-commit hook, I get the answer "Don't do this", not the answer "Here's how to do this, but it's reccomeded you don't", so I can't even easily try it to see if it's going to cause me problems.

• Deployment/provisioning tool for commercial applications (not developed in-house)

  - by mfinni

  I help manage a few hosted commercial applications, and we have a lot of manual processes involved when doing new customer-instance deployments into the shared (multitenant) environment. Allow me to describe the most relevant features, and then we can talk about the tools. We have an application on AIX, that requires dozens of changes to config files (some plain text, some XML) as well as a good number of commands to be run on multiple servers - some to start the new instance, some to restart our shared authentication and reporting engines, etc. The config changes follow templates, of course. The servers in question will also depend on the initial conditions specified by the implementer/deployer - we may choose to deploy a given customer to our servers in Europe, or one set of servers may be active-active whereas a different set of servers is active-passive - in short, there's a lot of complications. We have another application that run on IIS 6 and SQL. The DBAs don't want any automation of the SQL components and that's fine with me, but automating the IIS bit would be great. For a new customer instance, we make a filesystem copy of a template Virtual Directory target named after the new customer, make a new AppPool to match, edit a VirDir template .xml file to replace the filepaths and AppPool names with the new ones, and then make a new VirDir from the modified template XML to point to the new filesystem folder and app pool. For the first case, something like ControlTier or Chef might be good. For the second, the new(ish) Web Deploy from MS would probably do a good job. Has anyone used these tools or others to do something similar for applications? More of a nice-to-have, not a fixed requirement - Has anyone used anything that works on both platforms? I'm looking for something free, because the official word is that within a year, we will have whatever HP has renamed the OpsWare suite, which should be able to do stuff like this. Edit - based on someone's suggestion, looking at CFengine for the AIX application, it doesn't seem to address my pain. The problem isn't keeping a given config synced across dozens of servers, we have rsync for that. The problem is that onboarding a new customer instance touches dozens of files, putting pieces of the same or similar information into them - some are new stanzas in existing files, some are new files, and some are new directories. This is a several-hours-long process that is also error-prone because it's mostly done by hand. I guess I'm looking for config-file generation and management. I have built a small Perl script to do something similar for a much smaller case - it binds a CSV file into variables, and then does a copy-and-search-and-replace from a set of template config files. I could probably do the same here.

• Weblogic / EjbGen: worker manager configuration.

  - by Guillaume

  I want to declare a worker manager to perform some work in managed thread. Weblogic documentation tells that we can declare a global worker manager using the admin console or declare it in an ejb-jar.xml config file. I want to use the second option. But my ejb-jar.xml is generated by the ejbgen tool. There is no tag in ejbgen that would allow me to declare a worker manager. So how should I create a local worker manager declaration ?

• View a SYS.XMLTYPE returned from an Oracle function, using PL/SQL

  - by caerphilly

  I have an Oracle function that dynamically creates an XML document, and returns it in a SYS.XMLTYPE value. I want to run a query from SQL Developer that calls that function and prints the document (either via a select, or dbms_output - I don't care). But all the examples/documentation seem to refer to querying XML columns in tables, and I can't seem to get the syntax right for my particular usage. I'd like something like this: declare x SYS.XMLTYPE; begin x := my_package.my_function(); select x.getclobval() from x; -- doesn't work! end; How can I print out the value of the XML type variable 'x' in the above code?

• What does upload in Google AppEngine app.yaml do?

  - by Great Turtle

  I am going through the various Google AppEngine tutorials sometimes, and I just noticed something odd in a StackOverflow question about favicon.ico - specifically this question: http://stackoverflow.com/questions/887328/favicon-ico-not-found-error-in-app-engine - url: /favicon.ico static_files: media/img/favicon.ico upload: media/img/favicon.ico - url: /robots.txt static_files: media/robots.txt upload: media/robots.txt All of the posters included an "upload:" line in their app.yaml definitions The application appears to work the same with or without the upload: line, and I have not seen any mention of it in the official documentation. Where is it used, or what difference does it make if this line is included or not?

• Perl, treat string as binary byte array

  - by Mike

  In Perl, is it appropriate to use a string as a byte array containing 8-bit data? All the documentation I can find on this subject focuses on 7-bit strings. For instance, if I read some data from a binary file into $data my $data; open FILE, "<", $filepath; binmode FILE; read FILE $data 1024; and I want to get the first byte out, is substr($data,1,1) appropriate? (again, assuming it is 8-bit data) I come from a mostly C background, and I am used to passing a char pointer to a read() function. My problem might be that I don't understand what the underlying representation of a string is in Perl.

• How to replace values in multi-valued ESE column?

  - by Soonts

  I have a multi-valued short ASCII text column in one of the tables in my ESE database, that holds the person's phone numbers. I have the new set of values, and I'd like to wipe the old values completely, and only use the new values. The JET_bitSetRevertToDefaultValue bit doesn't seem to work. While the MSDN documentation says "It causes the column to return the default column value on subsequent retrieve column operations. All existing column values are removed.", I found that it does nothing (no return value is returned). Or, is there an easy way to find out how many values does the column contain (this could be zero, e.g. when I'm doing an insertion, not update)? If it was, I could just run a loop from 'nValues' to 1, erasing the value by setting it to the null while providing the itagSequence value, to achieve what I want. I'm programming C#, and using the latest version of ManagedEsent library. Thanks in advance!

• IWebBrowser2: how to force links to open in new window?

  - by Rob McAfee

  The MSDN documentation on WebBrowser Customization explains how to prevent new windows from being opened and how to cancel navigation. In my case, my application is hosting an IWebBrowser2 but I don't want the user to navigate to new pages within my app. Instead, I'd like to open all links in a new IE window. The desired behavior is: user clicks a link, and a new window opens with that URL. A similar question was asked and answered here and rather than pollute that answered post, it was suggested I open a new discussion. The members on the related post suggested I should be able to do this by trapping DISPID_BEFORENAVIGATE2, setting the cancel flag, and writing code to open a new window, but I've found out that the browser control gets lots of BeforeNavigate2 events that seem to be initiated by scripts on the main page. For example, amazon.com fires BeforeNavigate2 events like crazy, and they are not a result of link invocation. Replies appreciated!

• Applet User-agent

  - by Jonathan Barbero

  Hello! This is a simple question, but I didn´t found any documentation about this. When an applet makes a request, how is the user agent of the request. I want to know the applet user-agent expression to detect if a request comes from an applet. I make two test, with IE7 and Firefox 3.0.5 with JDK 1.6.0_03 and the user agent was "Mozilla/4.0 (Windows 2003 5.2) Java/1.6.0_03" in both, but I can´t generalize from two test. Thanks in advance, Jonathan.

• When does ref($variable) return 'IO'?

  - by Zaid

  Here's the relevant excerpt from the documentation of the ref function: The value returned depends on the type of thing the reference is a reference to. Builtin types include: SCALAR ARRAY HASH CODE REF GLOB LVALUE FORMAT IO VSTRING Regexp Based on this, I imagined that calling ref on a filehandle would return 'IO'. Surprisingly, it doesn't: use strict; use warnings; open my $fileHandle, '<', 'aValidFile'; close $fileHandle; print ref $fileHandle; # prints 'GLOB', not 'IO' perlref tries to explain why: It isn't possible to create a true reference to an IO handle (filehandle or dirhandle) using the backslash operator. The most you can get is a reference to a typeglob, which is actually a complete symbol table entry [...] However, you can still use type globs and globrefs as though they were IO handles. In what circumstances would ref return 'IO' then?

• Is there a way to find out if an iPhone / iPad app is installed already?

  - by eerok512

  I'm writing a freeware version of an app and would like to check if a user already has the unfree version installed, and print a message whose contents are conditional on the results of the installation check... anybody know if this is possible? the closest I've come to a solution is to make use of the CFPreferencesSetValue API with a kCFPreferencesAnyUser / kCFPreferencesCurrentHost pairing... I haven't tried it, but based on the documentation it sounds possible. however in my current specific situation this API will not be able to solve my problem, because I want to check for the presence of an app I wrote 4 months ago that didn't write any data to the CFPrefs registry... because back then I didn't know of it nor did I foresee this situation arising... the only way CFPrefs can assist me is in future apps now that I know it exists :) so I'm wondering if there are other ways to do it? any help will be appreciated :)

• jquery cookie - hoursToLive

  - by mathiregister

  Hi guys, i'm using the jquery cookie plugin. Everything works fine except the fact that I have no idea how to set an expiration-time for the cookie? $.cookie('opt_visible', 'true'); the jquery-cookie documentation says: hoursToLive (DEPRECATED for expiresAt) NUMBER For how many hours should the cookie be valid? (Passing 0 means to delete the cookie at the end of the browser session--this is default. Negative values will delete the cookie, but you should use the del() method instead.) That's exactly what I'd like to have. The cookie should be available as long as i'm browsing the site. As soon as i close the window or browsertab, the cookie should be deleted. How can i implement this hoursToLive thingy to my mentioned line above? Thank you

• when to use strncpy or memmove

  - by robUK

  Hello, gcc 4.4.4 c89 I have always used strncpy to copy strings. I have never really used memmove or memcpy very much. However, I am just wondering when would you decide whether to use strncpy, memmove, or memcpy? The code I am writing is for a client/server application. In the documentation they use bcopy. However, could I do the same with the others? bcopy((char*)server->h_addr, (char*)&serv_addr.sin_addr.s_addr, server->h_length); Many thanks,

• Datagrid for Symfony?

  - by Stick it to THE MAN

  I want to use a datagrid in one of my modules (Symfony 1.3, Propel ORM). I have spent a while searching the web, but everything I found expects a direct connection to teh db (mySQL) or is otherwise unsuitable. I found the datagrid plugin (http://symfony.swisscenter.com/datagrid/exemples), but the documentation/examples are in French - and I'm not too keen on learning French just for the sake of using the plugin - besides, if all the users are French speakers, then it will be difficult to get support/help if/when I do hget stuck. So my questions are: Is anyone aware of a good (PHP) datagrid component that I can use with SF? Is anyone out there (English speaker), using the SF datagrid plugin?

• Graphics card artifacting

  - by White Phoenix

  This is my current build: EVGA X58 (first generation) motherboard Intel i7 965 @ stock clocks 3x 2GB DDR3-1600 Corsair RAM at stock timings and voltages Corsair AX750 80 Plus Gold PSU 1 Optical Drive 1 Seagate 7200.10 500 GB drive 2x Western Digital Caviar Black 1 TB drives OCZ Vertex 1 60 GB EVGA GTX 460 Antec 1200 case HT-Omega Striker 7.1 Sound Card Windows 7 32-bit Professional (PAE Enabled) My graphics card started artifacting while I was playing a game. It artifacted, the display blinked, then I got an NVIDIA driver has crashed and recovered message. Kept going, more artifacts, another crash, but this time my display blanked out and I couldn't do anything. Restarted my computer - artifacting is in the BIOS - got to Windows 7 but it BSOD'd before I could even log in. I restarted the computer again - artifacts cleared themselves out and I managed to get to Win7, but it soon started blinking in and out and artifacting again. Checked the card temps and they're well within range. (50 idle, 70 full load) The ambient temperature here is about 80-85F with high humidity. Tried Safe Mode and it still froze up/BSOD'd. Already tried the following to fix this problem: - Reseat the graphics card and swapped in a different slot. - Removed cover on card and sprayed with compressed air to clean it out. - Swapped around memory and/or went with only using one stick at a time. - Underclocked card I called EVGA Tech Support and they said that the voltage on the 12V rail of my Corsair AX750 PSU was on the high end of the "acceptable" range (12.4V, highest within acceptable range is 12.6V - optimal is obviously 12V). They gave me an RMA number anyway, but I want to get a second opinion from you all before I send this thing off, as shipping from where I live to EVGA is kind of pricey. This PSU is only 6 months old. So that I don't have to play RMA tag, which case would be most likely? I'm strapped for cash at the moment so I want to reduce the amount of RMAs I have to do since shipping is expensive here. Is there any surefire way to test to see if it's really the graphics card or the PSU? I tried unplugging any devices that were connected to the 12V rail (except for my SSD and graphics card) as I do have 3 mechanical hard drives, but the voltage for that rail didn't drop (it remained at 12.4V). I'm fairly sure it isn't the drivers since I'm getting the artifacting at the BIOS too. Right now I'm back in Windows 7 but I don't know for how long until it messes up again. Any ideas?
