  • 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?

  • storing an integral value in a pointer variable while declaration

    - by benjamin button
    int main() { int *d=0; printf("%d\n",*d); return 0; } this works fine. >cc legal.c > ./a.out 0 if i change the statement int *d=0; to int *d=1; i see the error. cc: "legal.c", line 6: error 1522: Cannot initialize a pointer with an integer constant other than zero. so its obvious that it will allow only zero.i want to know what happens inside the memory when we do this int *d=0 which is making it valid syntax. I am just asking this out of curiosity!

  • Adding a variable href attribute to a hyperlink using XSLT

    - by Pete
    I need to create links using dynamic values for both the URL and the anchor text. I have column called URL, which contains URL's, i.e., http://stackoverflow.com, and I have a column called Title, which contains the text for the anchor, i.e., This Great Site. I figure maybe all I need to do is nest this tags, along with a little HTML to get my desired result: <a href="> <xsl:value-of select="@URL">"> <xsl:value-of select="@Title"/> </xsl:value-of> </a> In my head, this would render: <a href=" http://stackoverflow.com"> This Great Site </a> I know there's more to it, but I haven't been able to clearly understand what more I need. I think this issue has been addressed before, but not in a way I could understand it. I'd be more than happy to improve the question's title to help noobs like myself find this item, and hopefully an answer. Any help is greatly appreciated.

  • PHP form processing - how to capture text from field that has variable Name/ID

    - by user80151
    I have a form that has a field pulled from the database as a dropdown. I need to get the text selected in the dropdown but I don't know in advance what the field ID will be. This is basically just a form that has already been generated. I don't need to pull anything from the database, it's already on this page. All I need to do is get the form information and email it, no writing to the database. I know how to do the _Request for the other fields based on the ID but I'm not sure how to do this one. The ID changes. It can be ID=1, ID-2, etc. I need to do something like: _REQUEST form element where ID is LIKE "ID[*]" or something similar. Any suggestions or links to tutorials? Here are a couple samples of what the dropdown renders on the page: <div class="wrapperAttribsOptions"> <h4 class="optionName back"><label class="attribsSelect" for="attrib- 1">Model</label></h4> <div class="back"> <select name="id[1]" id="attrib-1"> <option value="45">VC3-4C</option> <option value="1">VC3-4PG</option> <option value="3">VC3-4SG</option> <div class="wrapperAttribsOptions"> <h4 class="optionName back"><label class="attribsSelect" for="attrib-14">SPK Model</label></h4> <div class="back"> <select name="id[14]" id="attrib-14"> <option value="43">SPK-4</option> <option value="44">SPK-8</option> </select> TIA

  • Passing an array for setting variable

    - by mathk
    Hi, I often see this idiom when reading php code: public function __construct($config) { if (array_key_exists('options', $config)) { ... } if (array_key_exists('driver_options', $config)) { ... } } Here I am concern with the way the parameter is used. If I were in lisp I would do: (defun ct (&key options driver_options) (do-something-with-option-and-driver_option)) But since I am in PHP I would rather have a constructor that take a list of parameter and let them be null if there a not require. So what do you guys think about having an array as parameter in other to do some initialization-or-whatever? In other to answer you have to take in account the point of view of the user of the function and the designer of the API. Also have you ever heard this has a code-smell? thanks

  • Variable popen calls in C

    - by Bushman
    I'm trying to execute MS-DOS DEL commands inside a Win32 C program, and I already know that system and popen can be used for this. However, the problem is that both require string literals (type const char) for the commands, and I need something like the DOS equivalent of dir ~ | grep -P '/\d{7,8}\.exe$/' | rm, which obviously can't use string literals. Is there some other subprocess function in C that allows for char arrays as arguments for process names?

  • Passing a JavaScript variable to a helper method

    - by Brendan Vogt
    I am using ASP.NET MVC 3 and the YUI library. I created my own helper method to redirect to an edit view by passing in the item's ID from the Model as such: window.location = '@Url.RouteUrl(Url.NewsEdit(@Model.NewsId))'; Now I am busy populating my YUI data table and would like to call my helper method like above, not sure if it is possible because I get the item's ID by JavaScript like: var formatActionLinks = function (oCell, oRecord, oColumn, oData) { var newsId = oRecord.getData('NewsId'); oCell.innerHTML = '<a href="/News/Edit/' + newsId + '">Edit</a>'; };

  • correct way to store an exception in a variable

    - by Evan Teran
    I have an API which internally has some exceptions for error reporting. The basic structure is that it has a root exception object which inherits from std::exception, then it will throw some subclass of that. Since catching an exception thrown in one library and catching it in another can lead to undefined behavior (at least Qt complains about it and disallows it in many contexts). I would like to wrap the library calls in functions which will return a status code, and if an exception occurred, a copy of the exception object. What is the best way to store an exception (with it's polymorphic behavior) for later use? I believe that the c++0x futures API makes use of something like this. So what is the best approach? The best I can think of is to have a clone() method in each exception class which will return a pointer to an exception of the same type. But that's not very generic and doesn't deal with standard exceptions at all. Any thoughts?

  • Make XStream ignore one specific private variable

    - by Tigraine
    Hi guys, I have a little problem with a class I am currently writing a save function for. I'm using XStream (com.thoughtworks.xstream) to serialize a class to XML using the DOMDriver. The class looks like this: public class World { private Configuration config; public World(Configuration config) { this.config = config; } } So, the issue here is that I do not want to serialize Configuration when serializing world, rather I'd like to give XStream a preconstructed Configuration instance when calling fromXml(). Problem here is mainly class design, Configuration holds a private reference to the GUI classes and therefore serializing Configuration means serializing the whole application completely with GUI etc.. And that's kind of bad. Is there a way to instruct XStream to not serialize the private field config, and upon load supply XStream with a configuration instance to use? greetings Daniel

  • Super Noob C++ variable help

    - by julian
    Ok, I must preface this by stating that I know so so little about c++ and am hoping someone can just help me out... I have the below code: string GoogleMapControl::CreatePolyLine(RideItem *ride) { std::vector<RideFilePoint> intervalPoints; ostringstream oss; int cp; int intervalTime = 30; // 30 seconds int zone =ride->zoneRange(); if(zone >= 0) { cp = 300; // default cp to 300 watts } else { cp = ride->zones->getCP(zone); } foreach(RideFilePoint* rfp, ride->ride()->dataPoints()) { intervalPoints.push_back(*rfp); if((intervalPoints.back().secs - intervalPoints.front().secs) > intervalTime) { // find the avg power and color code it and create a polyline... AvgPower avgPower = for_each(intervalPoints.begin(), intervalPoints.end(), AvgPower()); // find the color QColor color = GetColor(cp,avgPower); // create the polyline CreateSubPolyLine(intervalPoints,oss,color); intervalPoints.clear(); intervalPoints.push_back(*rfp); } } return oss.str(); } void GoogleMapControl::CreateSubPolyLine(const std::vector<RideFilePoint> &points, std::ostringstream &oss, QColor color) { oss.precision(6); QString colorstr = color.name(); oss.setf(ios::fixed,ios::floatfield); oss << "var polyline = new GPolyline(["; BOOST_FOREACH(RideFilePoint rfp, points) { if (ceil(rfp.lat) != 180 && ceil(rfp.lon) != 180) { oss << "new GLatLng(" << rfp.lat << "," << rfp.lon << ")," << endl; } } oss << "],\"" << colorstr.toStdString() << "\",4);"; oss << "GEvent.addListener(polyline, 'mouseover', function() {" << endl << "var tooltip_text = 'Avg watts:" << avgPower <<" <br> Avg Speed: <br> Color: "<< colorstr.toStdString() <<"';" << endl << "var ss={'weight':8};" << endl << "this.setStrokeStyle(ss);" << endl << "this.overlay = new MapTooltip(this,tooltip_text);" << endl << "map.addOverlay(this.overlay);" << endl << "});" << endl << "GEvent.addListener(polyline, 'mouseout', function() {" << endl << "map.removeOverlay(this.overlay);" << endl << "var ss={'weight':5};" << endl << "this.setStrokeStyle(ss);" << endl << "});" << endl; oss << "map.addOverlay (polyline);" << endl; } And I'm trying to get the avgPower from this part: AvgPower avgPower = for_each(intervalPoints.begin(), intervalPoints.end(), AvgPower()); the first part to cary over to the second part: << "var tooltip_text = 'Avg watts:" << avgPower <<" <br> Avg Speed: <br> Color: "<< colorstr.toStdString() <<"';" << endl But of course I haven't the slightest clue how to do it... anyone feeling generous today?

  • Variable width columns in a table

    - by Jack
    I'm using an HTML table for a calendar and I want to fill the cells with various events from my database. Usually they will land on weekends but some will run for long weekend, bank holidays or even the odd week day. How can I get my tables columns to expand and shrink accordingly. I'd like to avoid the use of javascript if possible. If this can't be done I'm going to need a tutorial to help me get my head around how to make div's positioning behave. cheers

  • jquery remove selected element and append to another

    - by KnockKnockWhosThere
    I'm trying to re-append a "removed option" to the appropriate select option menu. I have three select boxes: "Categories", "Variables", and "Target". "Categories" is a chained select, so when the user selects an option from it, the "Variables" select box is populated with options specific to the selected categories option. When the user chooses an option from the "Variables" select box, it's appended to the "Target" select box. I have a "remove selected" feature so that if a user "removes" a selected element from the "Target" select box, it's removed from "Target" and put back into the pool of "Variables" options. The problem I'm having is that it appends the option to the "Variables" items indiscriminately. That is, if the selected category is "Age" the "Variables" options all have a class of "age". But, if the removed option is an "income" item, it will display in the "Age Variables" option list. Here's the HTML markup: <select multiple="" id="categories" name="categories[]"> <option class="category" value="income">income</option> <option class="category" value="gender">gender</option> <option class="category" value="age">age</option> </select> <select multiple="multiple" id="variables" name="variables[]"> <option class="income" value="10">$90,000 - $99,999</option> <option class="income" value="11">$100,000 - $124,999</option> <option class="income" value="12">$125,000 - $149,999</option> <option class="income" value="13">Greater than $149,999</option> <option class="gender" value="14">Male</option> <option class="gender" value="15">Female</option> <option class="gender" value="16">Ungendered</option> <option class="age" value="17">Ages 18-24</option> <option class="age" value="18">Ages 25-34</option> <option class="age" value="19">Ages 35-44</option> </select> <select height="60" multiple="multiple" id="target" name="target[]"> </select> And, here's the js: /* This determines what options are display in the "Variables" select box */ var cat = $('#categories'); var el = $('#variables'); $('#categories option').click(function() { var class = $(this).val(); $('#variables option').each(function() { if($(this).hasClass(class)) { $(this).show(); } else { $(this).hide(); } }); }); /* This adds the option to the target select box if the user clicks "add" */ $('#add').click(function() { return !$('#variables option:selected').appendTo('#target'); }); /* This is the remove function in its current form, but doesn't append correctly */ $('#remove').click(function() { $('#target option:selected').each(function() { var class = $(this).attr('class'); if($('#variables option').hasClass(class)) { $(this).appendTo('#variables'); sortList('variables'); } }); });
