  • Is it possible to auto generate Getter/Setter from Array Values in PHP?

    - by Phill Pafford
    So I have a couple of arrays $array_1 = Array('one','two','three'); $array_2 = Array('red','blue','green'); Is there a dynamic way to create the Setters and Getters for an array with single value entries? So the class would be something like: class xFromArray() { } So the above if I passed $array_1 it would generate something like this: private $one; setOne($x) { $one = $x; } getOne() { return $one; } if I passed $array_2 it would generate something like this: private $red; setRed($x) { $red = $x; } getRed() { return $red; } So I would call it somehow like this? (My best guess but doesn't seem that this would work) $xFromArray = new xFromArray; foreach($array_1 as $key=>$data) { $xFromArray->create_function(set.ucfirst($data)($data)); echo $xFromArray->create_function(get.ucfirst($data)); }

  • What are these c++ statements doing

    - by codingguy3000
    void useproxynum ( ) { bUseProxy = true; return; }; void useacctnum ( ) { bUseProxy = false; return; }; Can anyone give me some insight into what these c++ statements are doing? There are in a header file. bUseProxy is defined above bool bUseProxy; I'm trying to figure out what useproxynum is (method call?) and I'm also trying to figure out how to find the code behind it. This is in Visual Studio 6.

  • How to implement fluent interface with a base class, in C++

    - by Vincenzo
    How can I implement this fluent interface in C++: class Base { public: Base& add(int x) { return *this; } } class Derived : public Base { public: Derived& minus(int x) { return *this; } } Derived d; d.add(1).minus(2).add(3).minus(4); Current code doesn't work since Base class doesn't know anything about Derived class, etc. I would be very thankful for a hint/suggestion.

  • NullPointerException while trying to bind at SimpleCursorAdapter

    - by hrskrs
    I have asked a question before where i found my mistake. However now i am facing with another problem. I have checked all the similar errors asked on StackOverflow but without success.Any help is appriciated. The idea here is that i am getting image names from DB so depending on those names images from Drawable folder will be shown in a listView together with a description but im getting an error of NullPointException at setViewValue. Here is the code snippet: private void populateListView() { ListView customListView = (ListView)findViewById(R.id.lvCustom); Cursor cursor = DBhelper.getAllimages(); startManagingCursor(cursor); String[] from = { DBhelper.COLUMN_PIC_URL, DBhelper.COLUMN_PIC_DESC}; int[] to = {R.id.ivImg, R.id.tvTitle}; SimpleCursorAdapter cursorAdapter = new SimpleCursorAdapter(this, R.layout.custom_listview_row, cursor, from, to, 0); cursorAdapter.setViewBinder(new ViewBinder() { @Override public boolean setViewValue(View view, Cursor cursor, int columnIndex) { ImageView imageImageView = (ImageView)findViewById(R.id.ivImg); String[] imgNames = new String[cursor.getCount()]; int[] imgResourceIds = new int[cursor.getCount()]; for(int i=0; i<cursor.getCount(); i++){ imgNames[i] = cursor.getString(cursor.getColumnIndex(DBhelper.COLUMN_PIC_URL)); imgResourceIds[i] = getResources().getIdentifier(imgNames[i], "drawable", getPackageName()); imageImageView.setImageResource(imgResourceIds[i]); cursor.moveToNext(); } return true; } }); customListView.setAdapter(cursorAdapter); } Here is the Error from LogCat: I have tried to log the output of imgNames[i] where it returns the url pic from the DB correctly and imgResourceIds[i] where it return the image resource id correctly also(it does not return NULL but something like: 295731). But it stops at imageImageView.setImageResource(imgResourceIds[i]); To see from where that NullPointerException is coming, i commented out imageImageView.setImageResource(imgResourceIds[i]);. This time imageNames(those with a TAG) and imgResourceIds(those system printed out) came correctly but doubled, when i removed cursor.MoveToNext() last row were doubled. Here is the screen shot of that: I have tried all the suggestions on stack about gettin a NullException but without success. Any idea where i am doing mistake?

  • Singleton design potential leak

    - by iBrad Apps
    I have downloaded a library off of github and have noticed that in the main singleton of the library there is a possible leak in this bit of code: +(DDGameKitHelper*) sharedGameKitHelper { @synchronized(self) { if (instanceOfGameKitHelper == nil) { [[DDGameKitHelper alloc] init]; } return instanceOfGameKitHelper; } return nil; } Now obviously there is no release or autorelease anywhere so I must do it but how and in what way properly? I have looked at various Singleton design patterns on the Internet and they just assign, in this case, instanceOfGameKitHelper to the alloc and init line. Anyway how would I properly fix this? Thanks!

    - by user3680715
    Hello everyone I have this code working fine but I want the script to stop on the mouse up event. Here is an example of what I have now.

  • How to discard const in c++

    - by Vincenzo
    This is what I'm trying to do and I can't: #include <string> using namespace std; class A { bool has() const { return get().length(); } string& get() { return s; } private: string s; }; The error I'm getting is: passing ‘const A’ as ‘this’ argument of ‘std::string& A::get()’ discards qualifiers I understand what the problem is, but how can I fix it? I really need has() to be const. Thanks.

  • Append an onClick event to an anchor tag using jquery?

    - by M.Woodard
    I am trying to add an onClick event to an anchor tag ... Previously i had ... <a href="somlink.html" onClick="pageTracker._link(this.href); return false;"> But i am trying to avoid the inline onClick event because it interferes with another script.. So using jQuery i am trying the following code ... <script> $(document).ready(function() { $('a#tracked').attr('onClick').click(function() {window.onbeforeunload = null; pageTracker._link(this.href); return false; }); }); </script> with the html like so <a id="tracked" href="something.html"> So my question is should this be working, and if not what would be the best solution?

  • Problems with sys.stdout.write() with time.sleep() in a function

    - by philipjkim
    What I wanted is printing out 5 dots that a dot printed per a second using time.sleep(), but the result was 5 dots were printed at once after 5 seconds delay. Tried both print and sys.stdout.write, same result. Thanks for any advices. import time import sys def wait_for(n): """Wait for {n} seconds. {n} should be an integer greater than 0.""" if not isinstance(n, int): print 'n in wait_for(n) should be an integer.' return elif n < 1: print 'n in wait_for(n) should be greater than 0.' return for i in range(0, n): sys.stdout.write('.') time.sleep(1) sys.stdout.write('\n') def main(): wait_for(5) # FIXME: doesn't work as expected if __name__ == '__main__': try: main() except KeyboardInterrupt: print '\nAborted.'

  • endpoints (bug?) behavior in xts

    - by Alex
    If I try to get endpoints for every year, for example, and do the following: xts.data <- xts(1:10000, order.by=seq(from=as.Date("1970-01-01"), by=1, len=10000)) z <- endpoints(xts.data, on="months", k=12) The return value for this is: > z [1] 0 10000 Same with numbers higher than 12. Why would xts simply not return indices of every year or 13th month starting from the beginning. Is it limited by the number of periods in a year? That is if i did: z <- endpoints(xts.data, on="weeks", k=54) This seems to work fine.

  • Getting Results from a Web SQL database

    - by andrew8088
    I'm playing around with the new Web SQL databases. Is there a way to return results from a SELECT statement? Here's my example: function getTasks (list) { db.transaction(function (tx) { list = list || 'inbox'; tx.executeSql("SELECT * FROM tasklist WHERE list = ?", [list], function (tx, results) { var retObj = [], i, len = results.rows.length; for ( i = 0; i < len; i++ ) { retObj[i] = results.rows.item(i); } return retObj; }); }); } The getTasks function is returning before the success callback does; is there a way to get the results out of the executeSql method, or do I have to do all the processing within the callback?

  • What's the outcome if I use free with new or delete with malloc?

    - by skydoor
    It is a compiler error or runtime error? The code below can be compiled! class Base{ void g(); void h(); }; int main() { Base* p = new Base(); free(p); return 0; } However it can't be compiled with a virtual function if I declare the class Base like this class Base{ virtual void g(); void h(); }; The code below can be compiled all the time, no matter the function is virtual or not. class Base{ void g(); void h(); }; int main() { Base* p = (Base*)malloc(sizeof(Base)); delete p; return 0; }

  • Prototype setStyle not working in IE6.

    - by Smickie
    Hi, I'm using prototype and setStyle in IE6 is just messing everything up. It's throwing a big error. I've Googled it but cant find a solution. I've identified the line in prototype with the IE script debugger, it's the final else block: setStyle: function(element, styles) { element = $(element); var elementStyle = element.style, match; if (Object.isString(styles)) { element.style.cssText += ';' + styles; return styles.include('opacity') ? element.setOpacity(styles.match(/opacity:\s*(\d?\.?\d*)/)[1]) : element; } for (var property in styles) if (property == 'opacity') element.setOpacity(styles[property]); else elementStyle[(property == 'float' || property == 'cssFloat') ? (Object.isUndefined(elementStyle.styleFloat) ? 'cssFloat' : 'styleFloat') : property] = styles[property]; return element; }, Anyone had this problem? P.S. normally I would use jQuery however this is someone else code I've had to update.

  • Partially fattening a list

    - by alj
    This is probably a really silly question but, given the example code at the bottom, how would I get a single list that retain the tuples? (I've looked at the itertools but it flattens everything) What I currently get is: ('id', 20, 'integer') ('companyname', 50, 'text') [('focus', 30, 'text'), ('fiesta', 30, 'text'), ('mondeo', 30, 'text'), ('puma', 30, 'text')] ('contact', 50, 'text') ('email', 50, 'text') what I would like is a single level list like: ('id', 20, 'integer') ('companyname', 50, 'text') ('focus', 30, 'text') ('fiesta', 30, 'text') ('mondeo', 30, 'text') ('puma', 30, 'text') ('contact', 50, 'text') ('email', 50, 'text') def getproducts(): temp_list=[] product_list=['focus','fiesta','mondeo','puma'] #usually this would come from a db for p in product_list: temp_list.append((p,30,'text')) return temp_list def createlist(): column_title_list = ( ("id",20,"integer"), ("companyname",50,"text"), getproducts(), ("contact",50,"text"), ("email",50,"text"), ) return column_title_list for item in createlist(): print item Thanks ALJ

  • Personalize Diff Command in Ubuntu

    - by acidboy
    I have two files, both with a lot of data, what I need is compare the first word of each file (each file always starts with a number, and each number could have many digits). The files are identical when these numbers are the same. Example: I have 3 files: a.txt, b.txt and c.txt a.txt content is "1 a b c 3 5 6 hjkj" b.txt content is "1 c f a 1234 h" c.txt content is "2 a b c 3 5 6 hjkj" diff a.txt b.txt should return "files are identical" diff a.txt c.txt should return "files are different" How can I compare them using the diff command?

  • how to get all the menu items below a certain parent in drupal?

    - by sprugman
    I really only need the mlid and title text for the first level below a certain menu item. Here's what I'm doing at the moment.
