  • Outputting an HTML entity character from a helper function

    - by morpheous
    I am using Symfony 1.3.2 on Ubuntu. I have written a little helper function (statsfoo) that prints out summary statistics about an item. I am using the helper function in my template like this: // In StatsHelper.php <?php function statsfoo($some_param) { return "<div class=\"sfoo\">&9830; the stats number for item is 42</div>" } //In showStatsSuccess.php <?php use_helper(Stats); <?php echo statsfoo($foobar, ESC_ENTITIES); I tried both ESC_ENTITIES and ESC_RAW. In both instances, the raw number (&9830) was displayed in the page. I want to display the diamond instead. What am I doing wrong and how can I fix this?

  • How would I design this table in SQL?

    - by RSharma
    I have a parent master table that is generic enough to hold the common information of the children. Since the children were substantially different, we created separate tables for them. So I have something like this: tblMaster -------- MasterID int Name varchar(50) --Common to all children and there are a bunch of fields like this ChildType int -- Type of Child either ChildOne or ChildTwo ChildID int -- need to store ChildOneID or ChildTwoID depending on type of Child, so that i can refer to children tblChild1 -------- ChildOneID int IDENTITY tblChild2 --------- ChildTwoID int IDENTITY Should I have a ChildID in the master that is either ChildOneID or ChildTwoID based on the ChildType column? I have a number of children and I have simplified it for this question. The other way is to add ChildOneID and ChildTwoID as columns in the master, but since i have a number of columns, I will have a lot of null columns EDIT: Any help is appreciated

  • Search a string to find which records in table are inside said string

    - by Improfane
    Hello, Say I have a string. Then I have a number of unique tokens or keywords, potentially a large number in a database. I want to search and find out which of these database strings are inside the string I provide (and get the IDs of them). Is there a way of using a query to search the provided string or must it be taken to application space? Am I right in thinking that this is not a 'full text search'? Would the best method be to insert it into the database to make it a full text search?

  • How can I retrieve monitor information?

    - by Jon Tackabury
    I am trying to retrieve the monitor ID's as shown in the Windows display properties (#1, 2... etc), but I can't seem to find a way. I have tried using EnumDisplayMonitors as well as EnumDisplayDevices. They both return something like "\.\DISPLAY1". However, this number doesn't always match the number shown by Windows, especially when 2 video cards are being used to drive 3 or more monitors. Is there an API call I am missing to retrieve this information, or is there a way to get it from the registry or somewhere else? Thanks! I have tried these methods: Win32: EnumDisplayMonitors, EnumDisplayDevices: Neither of these return monitors that aren't active, and neither one returns the correct IDs. WMI: "select * from Win32_DesktopMonitor" doesn't return all the monitors, and there is no ID. Registry: I have found the monitors in various locations, none of the places I found have the info I am looking for. Any help is much appreciated. :)

  • Accepting bank account information in a form

    - by jeffthink
    What security concerns are there when accepting a user's bank account information (account number and routing number) via a form on a page that is using SSL, and posting it back to the server where I then curl off a HTTPS request to send that information to an ACH service like First ACH or ACH Direct via their API? We wouldn't be saving the bank account information in our database. I know another option is to use Paypal's Mass Pay API, but they think it's unprofessional (at least for their business) to require customers to have a paypal account to get paid. Thoughts?

  • Android - LinearLayout Horizontal with wrapping children

    - by kape123
    Is there a property to set for Android's LinearLayout that will enable it to properly wrap child controls? Meaning - I have changeable number of children and would like to lay out them horizontally like: Example: Control1, Control2, Control3, ... I do that by setting: ll.setOrientation(LinearLayout.HORIZONTAL); foreach (Child c in children) ll.addView(c); However, if I have large number of children, last one gets cuts off, instead of going to next line. Any idea how this can be fixed?

  • How do we know the correct moves of Tower of Hanoi?

    - by Saqib
    We know that: In case of iterative solution: Alternating between the smallest and the next-smallest disks, follow the steps for the appropriate case: For an even number of disks: make the legal move between pegs A and B make the legal move between pegs A and C make the legal move between pegs B and C repeat until complete For an odd number of disks: make the legal move between pegs A and C make the legal move between pegs A and B make the legal move between pegs B and C repeat until complete In case of recursive solution: To move n discs from peg A to peg C: move n-1 discs from A to B. This leaves disc n alone on peg A move disc n from A to C move n-1 discs from B to C so they sit on disc n Now the questions are: How did we get this two solutions? Only by intuition? Or by logical/mathematical computation? If computation, how?

  • problem with fifos linux

    - by nunos
    I am having problem debugging why n_bytes in read_from_fifo function in client.c doesn't correspond to the value written to the fifo. It should only write 25 bytes but it tries to read a lot more (1836020505 bytes (!) to be exact). Any idea why this is happening? server.c: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <errno.h> #include <unistd.h> #include <fcntl.h> #include <sys/wait.h> #include <signal.h> #include <pthread.h> #include <sys/stat.h> typedef enum { false, true } bool; //first read the int with the number of bytes the data will have //then read that number of bytes bool read_from_fifo(int fd, char* var) { int n_bytes; if (read(fd, &n_bytes, sizeof(int))) { printf("going to read %d bytes\n", n_bytes); if (read(fd, var, n_bytes)) printf("read var\n"); else { printf("error in read var. errno: %d\n", errno); exit(-1); } } return true; } int main() { mkfifo("/tmp/foo", 0660); int fd = open("/tmp/foo", O_RDONLY); char var[100]; read_from_fifo(fd, var); printf("var: %s\n", var); return 0; } client.c: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <errno.h> #include <unistd.h> #include <fcntl.h> typedef enum { false, true } bool; //first write to fd a int with the number of bytes that will be written afterwards bool write_to_fifo(int fd, char* data) { int n_bytes = (strlen(data)) * sizeof(char); printf("going to write %d bytes\n", n_bytes); if (write(fd, &n_bytes, sizeof(int) != -1)) if (write(fd, data, n_bytes) != -1) return true; return false; } int main() { int fd = open("/tmp/foo", O_WRONLY); char data[] = "some random string abcdef"; write_to_fifo(fd, data); return 0; } Help is greatly appreciated. Thanks in advance.

  • Basic PHP question for Drupal Views theming

    - by oalo
    My PHP and programming knowledge is extremely basic, so this is probably a dumb question: I am theming a View in Drupal 6, and I want to add an id with a consecutive number to each item in the view (first item would have the id #item1, the second #item2, etc). I am customizing the style output (views-view-unformatted--MYVIEWNAME.tpl.php) and the row style output (views-view-fields--MYVIEWNAME.tpl.php), and I want to add a counter variable in the foreach loop in the style output tpl, and then use that variable in the row style output tpl, but the last one is not recognizing the variable. It does not give me any errors, but doesnt print the number. I understand this has probably something to do with variables visibility, how can I declare the counter variable in the style .tpl so I can the use it in the row style .tpl? Thank you

  • Help Forming An SQL Query That Selects The Max Difference Of Two Fields

    - by Frank
    I'm trying to select a record with the most effective votes. Each record has an id, the number of upvotes (int) and the number of downvotes (int) in a MySQL database. I know basic update, select, insert queries but I'm unsure of how to form a query that looks something like: SELECT * FROM topics WHERE MAX(topic.upvotes - topic.downvotes). Please excuse my made up SQL. The tutorials on SQL I find on the internet cover very basic stuff. Does anyone recommend a good book on this subject?

  • How to get arc4Sin() output into label/NSString

    - by Moshe
    I'm trying to take the output of arc4sin and put it into a label. (EDIT: You can ignore this and just post sample code, if this is too irrelevant.) I've tried: // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; NSString *number = [[NSString alloc] stringWithFormat: @"%@", arc4random() % 9]; label.text = number; } I've created an IBOutlet for "label" and connected it. What's wrong here?

It's possible that after the year's case I have some text but it shoud be ignored for sorting. I am using tablesorter jQuery's plugin and I am struggling to add a custom parser for this.

  • extension method phone format with country code as parameter

    - by frenchie
    Hi, I'm writing an extension method called ToPhoneFormat that formats a string of digits to phone numbers. Is it possible to add a parameter to the method that would enable me to call it like this: MyPhoneString.ToPhoneFormat(international code) That way, I could write MyPhoneString.ToPhoneFormat(1); to format a US phone number and MyPhoneString.ToPhoneFormat(33) to format a French phone number. I already wrote the method that does the formatting but I'm wondering how to build the constructor so that it works with a parameter when I'm calling it. Thanks.

  • preg_match find multiple partial appearances of a word in a string

    - by Rubytastic
    Any regex gurus around here? its driving me crazy. Say I have this string: "bookstore books Booking" I want to count the number "books" appears in this and return the number. Currently I have this which is not working: $string = "bookstore books Booking"; if (preg_match_all('/\b[A-Z]+books\b/', $string, $matches)) { echo count($matches[0]) . " matches found"; } else { echo "match NOT found"; } On top of this the "books" inside the preg_match_all should become a $var Anyone an idea how to count correctly?

  • In Python, how to use a C++ function which returns an allocated array of structs via a ** parameter?

    - by Jon-Eric
    I'd like to use some existing C++ code, NvTriStrip, in a Python tool. SWIG easily handles the functions with simple parameters, but the main function, GenerateStrips, is much more complicated. What do I need to put in the SWIG interface file to indicate that primGroups is really an output parameter and that it must be cleaned up with delete[]? /////////////////////////////////////////////////////////////////////////// // GenerateStrips() // // in_indices: input index list, the indices you would use to render // in_numIndices: number of entries in in_indices // primGroups: array of optimized/stripified PrimitiveGroups // numGroups: number of groups returned // // Be sure to call delete[] on the returned primGroups to avoid leaking mem // bool GenerateStrips( const unsigned short* in_indices, const unsigned int in_numIndices, PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false ); FYI, here is the PrimitiveGroup declaration: enum PrimType { PT_LIST, PT_STRIP, PT_FAN }; struct PrimitiveGroup { PrimType type; unsigned int numIndices; unsigned short* indices; PrimitiveGroup() : type(PT_STRIP), numIndices(0), indices(NULL) {} ~PrimitiveGroup() { if(indices) delete[] indices; indices = NULL; } };

  • Finding an available network port on the machine

    - by Tomer Vromen
    I'm trying to implement a simple FTP server (a variation of the EFTP protocol) in linux. When a client connects and sends the PASV command, the server should respond with a port number, so the client can connect to that port to transmit the file. How can the server choose a port number? Do I need to iterate through all the ports from 1024 to 65535 until I find a port that the process can bind to? I know that calling bind() with 0 as the port automatically chooses the port to bind to, but then how can I know which port was chosen? Many thanks.

  • Aes key length significance/implications

    - by cppdev
    Hi, I am using a AES algorithm in my application for encrypting plain text. I am trying to use a key which is a six digit number. But as per the AES spec, the key should be minimum sixteen bytes in length. I am planning to append leading zeros to my six digit number to make it a 16 byte and then use this as a key. Would it have any security implications ? I mean will it make my ciphertext more prone to attacks. Please help.

  • permutation need help to code

    - by Hunt
    Thank for your reply, first thing i wish to thank you for trying to help me out, and i have post this in few website also no one trying to help at all. For my code, what i wish to do is permutation count. it will count from top to bottom 1,2,3 1,2,3 1,2,3 output to 111 = 1 112 = 1 113 = 1 121 = 1 122 = 1 123 = 1 133 = 1 211 = 1 212 = 1 213 = 1 333 = 1 and continue till all number is count and also store to the array which can check how many count after all code will check the input number and count how many outcome and show the results with how many outcome and each have how many after permutation count. Its hard to do?. Anyway thank you for help.

  • How to create list of numbers and append its reverse to it efficiently in Ruby

    - by Kiwi
    Given a minimum integer and maximum integer, I want to create an array which counts from the minimum to the maximum by two, then back down (again by two, repeating the maximum number). For example, if the minimum number is 1 and the maximum is 9, I want [1, 3, 5, 7, 9, 9, 7, 5, 3, 1]. I'm trying to be as concise as possible, which is why I'm using one-liners. In Python, I would do this: range(1, 10, 2) + range(9, 0, -2) In Ruby, which I'm just beginning to learn, all I've come up with so far is: (1..9).inject([]) { |r, num| num%2 == 1 ? r << num : r }.reverse.inject([]) { |r, num| r.unshift(num).push(num) } Which works, but I know there must be a better way. What is it?
