  • PHP String Encoding Error

    - by Brian
    I'm trying to get the following code to output an IMG tag with the URL for Google Static Maps API http://code.google.com/apis/maps/documentation/staticmaps/#Imagesizes embedded in there... the result is that everything except the $address is being output successfully... what am I doing wrong? function event_map_img($echo = true){ global $post; $address = get_post_meta($post->ID, 'date_address', true); if($echo): echo '<img src="'.'http://maps.google.com/maps/api/staticmap?center='.$address.'&zoom=14&size=700x512&maptype=roadmap&markers=color:blue|label:X|'.$address.'&sensor=false" />'; else: return '<img src="'.'http://maps.google.com/maps/api/staticmap?center='.$address.'&zoom=14&size=700x512&maptype=roadmap&markers=color:blue|label:X|'.$address.'&sensor=false" />'; endif; }

  • What is the magic behind perl read() function and buffer which is not a ref ?

    - by alex8657
    I do not get to understand how the Perl read($buf) function is able to modify the content of the $buf variable. $buf is not a reference, so the parameter is given by copy (from my c/c++ knowledge). So how come the $buf variable is modified in the caller ? Is it a tie variable or something ? The C documentation about setbuf is also quite elusive and unclear to me # Example 1 $buf=''; # It is a scalar, not a ref $bytes = $fh->read($buf); print $buf; # $buf was modified, what is the magic ? # Example 2 sub read_it { my $buf = shift; return $fh->read($buf); } my $buf; $bytes = read_it($buf); print $buf; # As expected, this scope $buf was not modified

  • JSTL XML Transforms not working with nested XSL includes

    - by timxyz
    I have a bit of JSP that does this: <c:import url="/xsl/Transformer.xsl" var="xslt" /> <x:transform doc="${actionBean.dom}" xslt="${xslt}" xsltSystemId="/xsl/"> This transforms the XML exactly as expected so long as Transformer.xsl contains no <xsl:include> tags or so long as any documents it does include do not include anything. However, if I use an XSL which includes a document which in turn includes another document, I get the following error: ERROR: 'Invalid URI 'NestedInclude.xsl Could not resolve entity reference: "NestedInclude.xsl"'.' Note that the JSP is contained in the directory below the xsl documents. If all my XSLs and JSPs are in the same directory (and I remove the xsltSystemId attribute) then everything would work fine, but I don't really want to do this. Can anyone see anything I'm doing wrong, as it's a bit of a killer at the moment and the JSTL documentation is next to useless.

  • buffer overflow with boost::program_options

    - by f4
    Hello, I have a problem using boost:program_options this simple program, copy-pasted from boosts' documentation : #include <boost/program_options.hpp> int main( int argc, char** argv ) { namespace po = boost::program_options; po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message") ("compression", po::value<int>(), "set compression level") ; return 0; } fails with a buffer overflow. I have activated the "buffer security switch", and when I run it I get an "unknown exception (0xc0000409)" when I step over the line desc.add_options()... I use Visual Studio 2005 and boost 1.43.0. By the way it does run if I deactivate the switch but I don't feel comfortable doing so... unless it's possible to deactivate it locally. So do you have a solution to this problem? EDIT I found the problem I was linking against libboost_program_options-vc80-mt.lib which wasn't the good library.

  • Objetive C - Calling Methods in objects.

    - by Mace
    I'm new to Objective C, and I seem to be struggling with accessing a method of an object I created. I'm checking out the documentation , but I'm not entirely sure tha tthis is a job for a delegate. For example I have an object (1) that creates another object (2). I can access a method of the object (2) after I create it, but I can't access it from a method of object (1). I get a error that the object was not defined in this scope. If anyone can help I greatly appreciate it. I just need a nudge in the right direction so that I can at least get a grasp on how to think about the interaction between the objects.

  • XML::XML2JSON "0" Element

    - by Kevin C
    I'm using XML::XML2JSON in Perl to convert JSON data to XML, I am passing through the following data (snippet): {"question":{"isrequired":{"$t":"0"}}} and when I use the XML:XML2JSON-json2xml function to convert the JSON data into XML, I get the following (snippet): <isrequired/> I need to retain the "0" element in the "isrequired" tag, because at times, I will have empty JSON elements, and need the empty XML tag. I think the documentation is a bit vague (either that, or I don't understand it), but is this possible to do with this module? I would appreciate the help. Thanks.

  • How can I enable/disable network connection options programmatically

    - by nikie
    When I open the properties on a network connnection on windows, I see this dialog: In this dialog, in the check-listbox I can enable or disable options like "File or printer sharing", "client for microsoft networks" or network filter drivers. My question is: How can I enable/disable these options programatically? I didn't find anything that looks like this in the WMI documentation and I couldn't find any other Win32 API for this. I would prefer a C Win32 API or WMI interface, but a solution using any programming language is welcome. The question is language-agnostic.

  • Where can I find boost::fusion articles, examples, guides, tutorials?

    - by Kyle
    I am going to go ahead and shamelessly duplicate this question because the accepted answer is essentially "nope, no guides" and it's been nearly a year now since it's been asked. Does anyone know of any useful articles, guides, tutorials, etc. for boost::fusion besides the barebones documentation on boost.org? (which I'm sure is great as a reference after one has learned the library.) I'm completely open to, say, a link to a book on Amazon. Searched for it myself just now but all I came up with was green tea. The top links on Google aren't much better.

  • how to change locale in URL using Routing Filter gem Rails I18n application?

    - by Zack Xu
    I installed and set up routing-filter as described on the gem documentation page. https://github.com/svenfuchs/routing-filter It works for the default locale. For example, if I set up my default locale as :en,the site is in English, and if I set my default locale as :zh, the site is in Chinese. www.site.com/zh/home (the default locale path /en is automatically added to the URL) But how can I make my site support BOTH languages? when the default locale is :zh, I tried to change the URL by substituting the "zh" with "en" but the page is still in Chinese, not English. Is this something not supported by the routing-filter gem? If not, is there some other gem I can use? Or have I not set up the routing-filter gem properly? Thanks!

  • habtm multiple times with the same model

    - by Ermin
    I am trying to model a publications. A publication can have multiple authors and editors. Since it is possible that one person is an author of one publication and an editor of another, no separate models for Authors and Editors: class Publication < ActiveRecord::Base has_and_belongs_to_many :authors, :class_name=>'Person' has_and_belongs_to_many :editors, :class_name=>'Person' end The above code doesn't work, because it uses the same join table. Now I now that I can specify the name of the join table, but there is a warning in the API documentation is a warning about that which I don't understand: :join_table: Specify the name of the join table if the default based on lexical order isn’t what you want. WARNING: If you’re overwriting the table name of either class, the table_name method MUST be declared underneath any has_and_belongs_to_many declaration in order to work.

  • Import module stored in a cStringIO data structure vs. physical disk file

    - by Malcolm
    Is there a way to import a Python module stored in a cStringIO data structure vs. physical disk file? It looks like "imp.load_compiled(name, pathname[, file])" is what I need, but the description of this method (and similar methods) has the following disclaimer: Quote: "The file argument is the byte-compiled code file, open for reading in binary mode, from the beginning. It must currently be a real file object, not a user-defined class emulating a file." [1] I tried using a cStringIO object vs. a real file object, but the help documentation is correct - only a real file object can be used. Any ideas on why these modules would impose such a restriction or is this just an historical artifact? Are there any techniques I can use to avoid this physical file requirement? Thanks, Malcolm [1] http://docs.python.org/library/imp.html#imp.load_module

  • calling a service from an activity

    - by newbie
    Hi,I have been stuck on this issue for quite some time now.Have read the documentation and many tutorials and they just confuse me more.I hope someone will provide me a straightforward answer.It's really important.Thank you.. Ok ..so i want an activity to get some input from the user as and then send that string to a service.Then i want my service to run in a way so that i can use other applications while this one keeps running in the background.Also i don't want the service to keep running every second.What i want is for the service to get updated location of my current position every 10 minutes so i was thinkin if there could be a way to make my service to go to sleep n wake up evry 10 mins n check for updates.I don't want to show the update on the UI so i dont think i need to use an AIDL approach and also dont need to bind to the service.I js simply want to start the service as soon as the user enters the string and keep the service runing every 10 mins.I think it is really simple but m very confused.Please help.

  • linux's fork and system resources

    - by Dmitry Bespalov
    Suppose I have following code in linux: int main() { FILE* f = fopen("file.txt", "w"); fork(); fwrite("A", 1, 1, f); fclose(f); return 0; } What I know about fork from documentation, is that it makes the copy of current process. It copies state of the memory as well, so *f should be equal in both instances. But what happens with system resources, such as a file handle? In this example I open the file with write intentions, so only one instance can write into file, right? Which of the instances will actually write into file? Who should care further about the file handle, and call fclose() ?

  • Why does _GET in PHP wrongly decodes slash?

    - by Boaz
    Hi, Today I run into some oddity with PHP, which I fail find a proper explanation for in the documentation. Consider the following code: <?php echo $_GET['t']. PHP_EOL; ?> The code is simple - it takes a single t parameter on the url and outputs it back. So if you call it with test.php?t=%5Ca (%5c is a '\'), I expected to see: \a However, this is what I got: $ curl http://localhost/~boaz/test.php?t=%5Ca \\a Notice the double slash. Can anyone explains what's going on and give recipe for retrieving the strings as it was supplied on the URL? Thanks, Boaz

  • gnat programming studio auto fix issues

    - by Richard
    hi, I'm using GNAT Programming Studio to update some ada files. I have a style check, which for these old files produces literally thousands of warnings. Helpfully GPS has a little auto fix 'wrench' icon in the locations view, that's great but I don't want to go through and click the wrench ten thousand times. Is there a way to have it correct these errors automatically without me having to click each wrench? They are all right so I want to be changed automatically. I saw some documentation saying you could do it: http://www.adacore.com/wp-content/files/auto_update/gps-docs/Code-Fixing.html But I don't get the auto fix option when I right click. Maybe you need the pro version? I've tried everything I can think of. This would save hours of work, so it's really appreciated if someone could help on this. Thanks!

  • Python Library installation

    - by MacPython
    Hi everybody I have two questions regarding python libraries: I would like to know if there is something like a "super" python library which lets me install ALL or at least all scientific useful python libraries, which I can install once and then I have all I need. There is a number of annoying problems when installing different libraries (pythonpath, cant import because it is not installed BUT it is installed). Is there any good documentation about common installation errors and how to avoid them. If there is no total solution I would be interested in numpy, scipy, matplotlib, PIL Thanks a lot for the attention and help Best Z

  • Check result of AX_PYTHON_MODULE in configure.ac

    - by tmatth
    In using the m4_ax_python_module.m4 macro in configure.ac (AX_PYTHON_MODULE), one can know at configure time if a given module is installed. It takes two arguments, the module name, and second argument which if not empty, will lead to an exit, useful when the module is a must-have. In the case where you don't want a fatal exit, how do you test in configure.ac which modules were found or not? They output "yes" or "no" when configure is run, but that's all I've found so far. Basically If I have these lines in configure.ac: AX_PYTHON_MODULE(json,[]) AX_PYTHON_MODULE(simplejson,[]) How do I test which of the two modules were found? See http://www.gnu.org/software/autoconf-archive/ax_python_module.html#ax_python_module for documentation about this macro.

  • Watir changes highline's "ask" method

    - by grundic
    Hello! I've encoutered some strange functionality, when using Watir and Highline together. Here is simple example: require 'highline/import' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp require 'watir' comp = ask("Company? ") { |q| q.default = "MySuperCompany" } puts comp Here is an output: Company? |MySuperCompany| MySuperCompany [Company? ] => Company? Maybe it's a bug? I've also found in documentation for highline, that If @question is set before ask() is called, parameters are ignored and that object (must be a HighLine::Question) is used to drive the process instead. Sorry, I'm not a ruby guru :-(

  • FieldError when annotating over foreign keys

    - by X_9
    I have a models file that looks similar to the following: class WithDate(models.Model): adddedDate = models.DateTimeField(auto_now_add=True) modifiedDate = models.DateTimeField(auto_now=True) class Meta: abstract = True class Match(WithDate): ... class Notify(WithDate): matchId = models.ForeignKey(Match) headline = models.CharField(null=True, blank=True, max_length=10) For each Match I'm trying to get a count of notify records that have a headline. So my call looks like matchObjs = Match.objects.annotate(notifies_made=Count('notify__headline__isnull')) This keeps throwing a FieldError. I've simplified the query down to matchObjs = Match.objects.annotate(notifies_made=Count('notify')) And I still get the same FieldError... I've seen this work in other cases (other documentation, other SO questions like this one) but I can't figure out why I'm getting an error. The specific error that is returned is as follows: Cannot resolve keyword 'notify' into field. Choices are: (all fields from Match model) Does anyone have a clue as to why I can't get this annotation to work across tables? I'm baffled after looking at the other SO question and various Django docs where I've seen this done. Edit: I am using Django 1.1.1

  • What are real-world examples of Gradle's dependency graph?

    - by Michael Easter
    As noted in the documentation, Gradle uses a directed acyclic graph (DAG) to build a dependency graph. From my understanding, having separate cycles for evaluation and execution is a major feature for a build tool. e.g. The Gradle doc states that this enables some features that would otherwise be impossible. I'm interested in real-world examples that illustrate the power of this feature. What are some use-cases for which a dependency graph is important? I'm especially interested in personal stories from the field, whether with Gradle or a similarly equipped tool. I am making this 'community wiki' from the outset, as it will be difficult to assess a 'correct' answer.

  • AsyncTask Threading Rule - Can it really only be used once?

    - by stormin986
    In the documentation on AsyncTask it gives the following as a rule related to threading: The task can be executed only once (an exception will be thrown if a second execution is attempted.) All this means is that you have to create a new instance of the class every time you want to use it, right? In other words, it must be done like this: new DownloadFilesTask().execute(url1, url2, url3); new DownloadFilesTask().execute(url4, url5, url6); Or conversely, you can NOT do the following: DownloadFilesTask dfTask = new DownloadFilesTask(); dfTask().execute(url1, url2, url3); dfTask().execute(url4, url5, url6); Can someone verify this is an accurate interpretation? I realize I pretty much just answered this for myself as I was typing this out... But it wasn't immediately obvious to me so I think this would be useful to have posted nonetheless.

  • Where does Subversion physically stores its DataBase ?

    - by Mika Jacobi
    After reading many introductions, starting guides, and documentation on SVN, I still cannot figure out where is my versioning data stored. I mean physically. I have over 3 GB of code checked in, and the repo is just a few MB large. This is still Voodoo for me. And, as a coder, I don't really believe in Magic. EDIT : A contributor stated that not all the code was stored in the repo, is that true ? I mean, if I delete my local working copy I still can get back my source code for the repository... If so, I still can't understand how such a compression can occur on my code...

  • CouchDB Versioning / Auditing

    - by Cory
    I'm attempting to use CouchDB for a system that requires full auditing of all data operations. Because of its built in revision-tracking, couch seemed like an ideal choice. But then I read in the O'Reilly textbook that "CouchDB does not guarantee that older versions are kept around." I can't seem to find much more documentation on this point, or how couch deals with its revision-tracking internally. Is there any way to configure couch either on a per-database, or per-document level to keep all versions around forever? If so, how?

  • Multiple ports listed in SQL Server connection string

    - by BBlake
    I have a legacy VB6 app where the servername, databasename, username, etc are defined in an INI file, but the port number for the connection string (the default 1433) is hard coded in the app. It's being moved to a new sql server back end that runs off a different port number. I'm trying to avoid having to alter and recompile the application which entails signifigant retesting, documentation, etc. I tried altering the INI file so that for the new server I have put in: SERVERNAME\INSTANCE,NEWPORTNUMBER This effectively builds the connection with Data Source = SERVERNAME\INSTANCE,NEWPORTNUMBER,1433; This appears to work correctly as it connects to the database when I run the app. It appears to me that the ,1433 portion is being ignored. Is this a valid assumption or will this cause me some problem I'm not seeing here?

  • What issues carry the highest risk in a software project?

    - by Mehrdad Afshari
    Clearly, software projects are different from other industries in terms of many things like for instance, quality assurance, project progress measurement, and many other things. Unique characteristics of software projects also makes the risk management process unique. Lots of issues in a project might lead it to unacceptable delay or failure to deliver business value. They might even make a complete disaster in the project. What are the deadliest risk factors in a software project? How to analyze, prevent and handle them? Particularly, I'm interested in the issues that you can detect from the beginning and you should keep an eye on (for example, you might be told about a third-party API that the current application uses and lacks documentation). Please share your experiences if they are relevant.
