  • How to remove multiple instances and just have one instance while multiple function calls in php ?

    - by Rachel
    public function getHelperInstance() { $user = new Helper(); $user->set($result['data']); return $user; } I am calling getHelper() class multiple times and if $user is not empty than am calling getHelperInstance(), now in my case getHelperInstance() always creates a new instance of Helper() class and so every time I call getHelperInstance() function am creating a new instance of Helper() so is there any way where can I can just create one instance of Helper() and use it multiple times instead of creating a new instance everytime. Any suggestions !!! public function getHelper() { $user = array(); if (!empty($user)) { $user = $this->getHelperInstance(); } return $user; }

  • How to sanely read and dump structs to disk when some fields are pointers?

    - by bp
    Hello, I'm writing a FUSE plugin in C. I'm keeping track of data structures in the filesystem through structs like: typedef struct { block_number_t inode; filename_t filename; //char[SOME_SIZE] some_other_field_t other_field; } fs_directory_table_item_t; Obviously, I have to read (write) these structs from (to) disk at some point. I could treat the struct as a sequence of bytes and do something like this: read(disk_fd, directory_table_item, sizeof(fs_directory_table_item_t)); ...except that cannot possibly work as filename is actually a pointer to the char array. I'd really like to avoid having to write code like: read(disk_df, *directory_table_item.inode, sizeof(block_number_t)); read(disk_df, directory_table_item.filename, sizeof(filename_t)); read(disk_df, *directory_table_item.other_field, sizeof(some_other_field_t)); ...for each struct in the code, because I'd have to replicate code and changes in no less than three different places (definition, reading, writing). Any DRYer but still maintainable ideas?

  • C# Image.Clone to byte[] causes EDIT.COM to open on Windows XP

    - by JayDial
    It appears that cloning a Image and converting it to a byte array is causing EDIT.COM to open up on Windows XP machines. This does not happen on a Windows 7 machine. The application is a C# .NET 2.0 application. Does anyone have any idea why this may be happening? Here is my Image conversion code: public static byte[] CovertImageToByteArray(Image imageToConvert) { imageToConvert.Clone() as Image; if(clone == null) return null; imageToConvert.Dispose(); byte[] imageByteArray; using (MemoryStream ms = new MemoryStream()) { clone.Save(ms, clone.RawFormat); imageByteArray = ms.ToArray(); } return imageByteArray; } public static Image ConvertByteArrayToImage(byte[] imageByteArray, ImageFormat formatOfImage) { Image image; using ( MemoryStream ms = new MemoryStream(imageByteArray, 0, imageByteArray.Length)) { ms.Write(imageByteArray, 0, imageByteArray.Length); image = Image.FromStream(ms, true); } return image; } Thanks Justin

  • Custom "Very Long Int" Division Issue

    - by befall
    Hey everyone, So, for a very silly project in C++, we are making our own long integer class, called VLI (Very Long Int). The way it works (they backboned it, blame them for stupidity) is this: User inputs up to 50 digits, which are input as string. String is stored in pre-made Sequence class, which stores the string in an array, in reverse order. That means, when "1234" is input, it gets stored as [4|3|2|1]. So, my question is this: How can I go about doing division using only these arrays of chars? If the input answer is over 32 digits, I can't use ints to check for stuff, and they basically saying using long ints here is cheating. Any input is welcome, and I can give more clarification if need be, thanks everyone.

  • Loading table sections when using headers

    - by Luis Tovar
    I cant seem to wrap my head around this. I have googled, and overstacked for hours now looking for examples that i can relate to. What I have is two arrays. The name of my first NSMutableArray is "showDates". I have 3 objects in here. Object 0: "Today, May 20th" Object 1: "Tomorrow, May 21st" Object 2: "Saturday, May 22nd" Then I have my second NSMutableArray named "showTimes" I have about 15 objects in there with strings in each object. ( i hope that makes sense? ) Each object is structured like this: Object 0: showID @"98022" eventID @"833" showTime @"1:30pm" showDate @"Today, May 20th" auditorium @"9" venue @"2991" Object 1: showID @"98222" eventID @"813" showTime @"2:30pm" showDate @"Tomorrow, May 21st" auditorium @"9" venue @"2991" Etc, etc, .... I have the headers working great in my tableView, but I cant seem to figure out how to add the objects in my "showTimes" array under the correct header. Any help would be greatly appreciated.

  • Split String in C# without delimiter (sort of)

    - by Zach
    Hi, I want to split a string in C#.NET that looks like this: string Letters = "hello"; and put each letter (h, e, l, l, o) into an array or ArrayList. I have no idea what to use as the delimiter in String.Split(delimiter). I can do it if the original string has commas (or anything else): string Letters = "H,e,l,l,o"; string[] AllLettersArray = Letters.Split(",".ToCharArray()); But I have no idea what to use in a case with (supposedly) no delimiter. Is there a special character like Environment.Newline? Thanks.

  • how to open many files simultaneously for reading in c

    - by monkeyking
    I'm trying to port some of my c++ code into c. I have the following construct class reader{ private: FILE *fp; alot_of_data data;//updated by read_until() method public: reader(const char*filename) read_until(some conditional dependent on the contents of the file, and the arg supplied) } Im then instantiating hundreds of these object and iterate over them using several 'read_until()' for each file until allfiles is at eof. I'm failing to see any clever way to do this in c, the only solution I can come up with is making an array of FILE pointers, and do the same with all the private member data from my class. But this seems very messy, can I implement the functionality of my class as a function pointer, or anything better, I think I'm missing a fundamental design pattern? The files are way to big to have all in memory, so reading everything from every file is not feasible Thanks

  • Jquery javascript - How can I let users 'undo' their modifications?

    - by Bill Zimmerman
    Hi, i have a basic jquery app that allows a user to edit and manipulate some lists on a page. What I would like to do is have a button 'restore original list' that the user can press to undo his modifications. What is the best way to do this? I was thinking of just copying the DOM from the list down, and pasting it in a hidden element someplace else on the page. Is this the best way to do this? I also noticed that jquery has a .data() function which I could use if I converted the data to an array and stored it this way. What are the advantages and disadvantages? Also, I'm open to any suggestions people have if there is some method I haven't thought of. Thanks for your help!

  • Finding many local max in an image (using MatLab)

    - by wenh42
    How do you go about figuring our multiple max in a 2D image where the max aren't necessarily all the same height? I have found that the imregionalmax(), imextendedmax(), and findpeaks() functions aren't necessarily that helpful because they give many local max that are really just maxes within the background noise. I tried bw=arrayimdilate(array,[1 1 1; 1 0 1; 1 1 1]) but that also is kind of limited for the same reasons (same thing with expanding the matrix that it uses). I'd definitely appreciate some help..

    I'm trying to build a Rails app where I have to access the Zomato API Could anybody guide me on how to create the Controller and View. Suppose I want to get the name of the restaurant from this URL: Restaurant, how do I write the controller and views for it. Currently, I'm using HTTParty gem.

  • How can I restore the order of an (incomplete) select list to its original order?

    - by Rob
    I have two Select lists, between which you can move selected options. You can also move options up and down in the right list. When I move options back over to the left list, I would like them to retain their original position in the list order, even if the list is missing some original options. This is solely for the purpose of making the list more convenient for the user. I am currently defining an array with the original Select list onload. What would be the best way to implement this?

  • Another dynamic memory allocation bug.

    I'm trying to allocate memory for a multidimensional array (8 rows, 3 columns). Here's the code for the allocation (I'm sure the error is clear for you) char **ptr = (char **) malloc( sizeof(char) * 8); for (i = 0; i < 3; i++) ptr[i] = (char *) malloc( sizeof(char) * 3); The crash happens when I reference this: ptr[3][0]; Unhandled exception at 0x0135144d in xxxx.exe: 0xC0000005: Access violation writing location 0xabababab. Are there any recommended references/readings for this kind of subject? Thanks.

  • Retain count = 0 in other function? memory-management problem?

    - by rdesign
    Hey guys, I declared a NSMutableArray in the header-file with: NSMutableArray *myMuArr; and @property (nonatomic, retain) NSMutableArray *myMuArr; In the .m file I've got a delegate from an other class: -(void)didGrabData:(NSArray*)theArray { self.myMuArr = [[[NSMutableArray alloc] initWithArray:myMuArr]retain]; } If I want to access the self.myMuArr in cellForRowAtIndexPath it's empty (I checked the retain count of the array and it's 0) What am I doing wrong? Of course it's released in the dealloc, no where else. I would be very thankfull for any help :0)

  • Regex to get rid of everything past the first sentence in a string in php

    - by andufo
    I need to get rid of everything after the first dot (if there is more than 1 sentence), but at the same time, cases like e.g. have to be omited. Some line e.g., when people do something. Extra content. Some line (some parenthesis). Extra content. I need to get rid of the "Extra content.". The returning value should be: Some line e.g., when people do something. Some line (some parenthesis). So far I've come with this regex taken from other threads, but it only finds the dots and split the string into an array. preg_replace('/(?<!\.)\.(?!(\s|$|\,|\w\.))/','',$text); Any ideas? Thanks.

  • Temporarily disabled NSArrayController filterPredicate, or consult ManagedObjectContext?

    - by ndg
    I have an NSArrayController which is bound to a class in my Managed Object Context. During runtime the NSArrayController can have a number of different filter predicates applied. At certain intervals, I want to iterate through my NSArrayController's contents regardless of the filter predicate applied to it. To do this, I set the filterPredicate to nil and then reinstate it after having iterated through my array. This seems to work, but I'm wondering if it's best practice? Should I instead be polling my Managed Object Context manually? NSPredicate *predicate = nil; predicate = [myArrayController filterPredicate]; [myArrayController setFilterPredicate:nil]; for(MyManagedObject *object in [myArrayController arrangedObjects]) { // ... } [myArrayController setFilterPredicate:predicate];

Since there is only one tag called city a loop isn't really needed but I can't get it to work any other way

  • Help with a MySQL SELECT WHERE Clause

    - by Dr. DOT
    A column in my table contains email addresses. I have a text string that contains the a few usernames of email addresses separated by commas. I can make text sting into an array if necessary to get my SELECT WHERE clause to work correctly. Text string search argument is 'bob,sally,steve' I want to produce a WHERE clause that only returns rows where the username portion of the email address in the table matches one of the usernames in my text string search argument. Thus a row with [email protected] would not be returned but [email protected] would be. Does anyone have a WHERE clause sample that produces this result? Thanks.

  • Call to a member function query() on a non-object

    Ok, this is so weird!!! I am running PHP Version 5.1.6 when I try and run the code below it gives a fatal error of an object that has not been instantiated. As soon as I un-comment this line of code //$cb_db = new cb_db(USER, PASSWORD, NAME, HOST); everything works. Even though I have declared the $cb_db object as global within in the method.

  • Magento - Programmatically added products don't show up

    - by Lucasmus
    I am trying to import products using a custom made import profile. Here I set some values on the product and then save it, like this: $product = Mage::getModel('catalog/product'); $data = array(); // Inbetween I fill $data with some values $product->addData($data); $product->save(); However, the products do show up in the admin, but do not show up on the frontend (I did add them to categories). The odd thing is, they do appear on the frontend once I open them in the admin and save them again (without modifying anything). Am I forgetting something, or some value that is somehow set by that action? I tried to rebuild all indices in the backend and to clear the cache, but this does not work, contrary to Magento API: Rebuild Indexes after adding new products.
