  • PDO and SQL IN statements

    - by Sai
    Im using a sequel for search like this using PDOs $states = "'SC','SD'"; $sql = "select * from mytable where states in (:states)"; $params = array(':states'=>$states); and I use my function $result = $this->selectArrayAssoc($sql, $params); where my selectArrayAssoc function as following public function selectArrayAssoc($sql, $params = array()){ try{ $sth = $this->db->prepare($sql); $sth->execute($params); $result = $sth->setFetchMode(PDO::FETCH_ASSOC); return $sth->fetchAll(); }catch(PDOException $e){ print $e->getMessage(); //Log this to a file later when in production exit; } } it does not take the quoted variables, I think it is suppressing, in such cases how to deal with this.

  • NSMutableDictionary of NSMutableSets... sorting this out

    - by Mike
    I have a NSMutableDictionary of NSMutableSets. Each set entry is a string, something like this: NSMutableSet *mySet = [NSMutableSet setWithObjects: [NSString stringWithFormat:@"%d", time1], [NSString stringWithFormat:@"%d", time2], [NSString stringWithFormat:@"%d", time3], nil]; // time 1,2,3, are NSTimeInterval variables then I store each set on the dictionary using this: NSString *rightNowString = [NSString stringWithFormat:@"%d", rightNow]; [myDict setValue:mySet forKey:rightNow]; // rightNow is NSTimeInterval as rightNow key can occur out of order, I end with a NSDictionary that is not ordered by rightNow. How can I sort this NSDictionary by its keys considering that they are numbers stored as strings on the dictionary...? I don't care for ordering the sets, just the dictionary. thanks for any help.

  • Prevent python from printing newline

    - by wrongusername
    I have this code in Python inputted = input("Enter in something: ") print("Input is {0}, including the return".format(inputted)) that outputs Enter in something: something Input is something , including the newline I am not sure what is happening; if I use variables that don't depend on user input, I do not get the newline after formatting with the variable. I suspect Python might be taking in the newline as input when I hit return. How can I make it so that the input does not include any newlines so that I may compare it to other strings/characters? (e.g. something == 'a')

  • Trouble using opaque pointers in Objective C++

    - by morgancodes
    The answer to this quesion explains that opaque pointers are a good way to include C++ member variables in an Objective C++ header. I'm getting compile errors when trying to follow the example. Here's the relevant code from my header, with the corresponding compiler errors shown as comments: struct ADSR_opaque; // error: forward declaration of 'struct ADSR_opaque' @interface LoopyPulser : NSObject{ float _pulseRate; UInt32 tickInterval; UInt32 step; InMemoryAudioFile * audioFilePlayer; ADSR_opaque* env; // error: expected specifier-qualifier-list before 'ADSR_opaque' Pattern * pattern; float loopLengthRatio; float volume; } Is there something simple I'm doing wrong here?

  • Is there a way to put relationships/contraints into CSS?

    - by hekevintran
    In every design tool or art principle I've heard of, relationships are a central theme. By relationships I mean the thing you can do in Adobe Illustrator to specify that the height of one shape is equal to half the height of another. You cannot express this information in CSS. CSS hard-codes all values. Using a language like LESS that allows variables and arithmetic you can get closer to relationships but it's still a CSS variant. This inability in my mind is the biggest problem with CSS. CSS is supposed to be a language that describes the visual component of a Web page but it ignores relationships and contraints, ideas that are at the core of art. How possible is it to imagine a new Web design language that can express relationships and contraints that can be implemented in JavaScript using the current CSS properties?

  • What makes a bad programming language bad?

    - by sub
    We have all seen things like the typing system of JavaScript (There is a funny post including a truth table somewhere around here). I consider this one of the main things that makes a programming language bad. Other things that spring to mind: Bad Error messages (Either obfuscated so you can't figure out whats wrong, not existing or simply too long and red) The language wasn't planned and just grew uncontrolled in all directions (PHP?) The language encourages bad programm(er/ing) habits such as: Global variables everywhere, bad variable names Inconsistent naming conventions inside the language I can't come up with any more at the moment and would be very happy to read what you think about this. What shouldn't be missing in a language created to be as bad (from the perspectives of the programmer, the company that hires to programmer, the team leader and the customer) as possible? (I ask this because I'm designing a bad, experimental language at the moment)

  • Is there a Django template tag that lets me set a context variable?

    - by hekevintran
    I want to be able to set variables in a template to string values. I wrote a tag, but it doesn't seem to change the context. The intended use is: {% define my_var as "a string" %} class DefineNode(Node): def __init__(self, value, variable_name, nodelist): self.value = value self.variable_name = variable_name self.nodelist = nodelist def __repr__(self): return "<DefineNode>" def render(self, context): context[self.variable_name] = self.value return '' @register.tag def define(parser, token): bits = list(token.split_contents()) if len(bits) != 4: raise TemplateSyntaxError("%r expected format is 'value as variable'" % bits[0]) if bits[1][0] in ('"', "'") and bits[1][-1] == bits[1][0]: value = bits[1][1:-1] nodelist = parser.parse(('enddefine',)) parser.delete_first_token() return DefineNode(value, bits[3], nodelist) I

  • [PHP] Difference between normal and magic setters and getters

    - by Saif Bechan
    I am using a magic getter/setter class for my session variables, but I don't see any difference between normal setters and getters. The code: class session { public function __set($name, $value) { $_SESSION[$name] = $value; } public function __unset($name) { unset($_SESSION[$name]); } public function __get($name) { if(isset($_SESSION[$name])) { return $_SESSION[$name]; } } } Now the first thing I noticed is that I have to call $session->_unset('var_name') to remove the variable, nothing 'magical' about that. Secondly when I try to use $session->some_var this does not work. I can only get the session variable using $_SESSION['some_var']. I have looked at the PHP manual but the functions look the same as mine. Am I doing something wrong, or is there not really anything magic about these functions.

  • Smarty debug mode not displaying included templates.

    - by Kyle Sevenoaks
    On www.euroworker.no/order I have set Smarty's debug mode on with {debug output=html} in the header, so it will debug every page. But it says: Smarty Debug Console included templates & config files (load time in seconds): no templates included And after a list of template variables, {$cart} Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 561962 bytes) in /home/euroworkerno/www/library/smarty/libs/plugins/modifier.debug_print_var.php on line 30 It also doesn't display a list of templates for any url.. This is strange, can anyone point me to why it won't display the lit of .tpls? I need to find some HTML comments that someone has left in to rid IE of a display bug. Thanks.

  • Why the good append syntax is so ugly, asks python newbie

    - by Cawas
    Now following my series of "python newbie questions" and based on another question. Go to http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html#other-languages-have-variables and scroll down to "Default Parameter Values". There you can find the following: def bad_append(new_item, a_list=[]): a_list.append(new_item) return a_list def good_append(new_item, a_list=None): if a_list is None: a_list = [] a_list.append(new_item) return a_list So, question here is: why is the "good" syntax over a known issue ugly like that in a programming language that promotes "elegant syntax" and "easy-to-use"? Why not just something in the definition itself, that the "argument" name is attached to a "localized" mutable object like: def better_append(new_item, a_list=[].local): a_list.append(new_item) return a_list I'm sure there would be a better way to do this syntax, but I'm also almost positive there's a good reason to why it hasn't been done. So, anyone happens to know why?

  • How to force myself to follow naming and other conventions

    - by The King
    Hi All, I believe, I program good, atleast my code produces results... But I feel I have drawback... I hardly follow any naming conventions... neither for variables.. nor for methods... nor for classes... nor for tables, columns, SPs... Further to this, I hardly comment anything while programming... I always think that, Let me first see the results and then I will come and correct the var names and other things later... (Thanks to visual studio's reflection here)... But the later does not come... So, I need tips, to force myself to adopt to the practice of following naming conventions, and commenting... Thanks for your time

  • Force maximum width and height for PHPThumb images

    - by Peter
    PHPThumb provides two great variables setting the output maximum width and height BUT "This is always overridden by ?w=_ GETstring parameter" $PHPTHUMB_CONFIG['output_maxwidth'] = 720; $PHPTHUMB_CONFIG['output_maxheight'] = 720; You can also set defaults, and for landscape/portrait: $PHPTHUMB_DEFAULTS['w'] = 720; $PHPTHUMB_DEFAULTS['h'] = 720; $PHPTHUMB_DEFAULTS['hp'] = 720; $PHPTHUMB_DEFAULTS['wl'] = 720; You can set the getsringoverride to enforce the default width/height but then you can't have width/height smaller than the default. $PHPTHUMB_DEFAULTS_GETSTRINGOVERRIDE = false; There doesn't seem to be a way to allow the get paramaters to be used but if entering a value higher than the output_maxwidth/height it outputs that size, not the maximum. How can the output be explicitly restricted to a maximum size, hence protecting the source images?

  • Reading UDP Packets

    - by Thomas Mathiesen
    I am having some trouble dissecting a UDP packet. I am receiving the packets and storing the data and sender-address in variables 'data' and 'addr' with: data,addr = UDPSock.recvfrom(buf) This parses the data as a string, that I am now unable to turn into bytes. I know the structure of the datagram packet which is a total of 28 bytes, and that the data I am trying to get out is in bytes 17:28. I have tried doing this: mybytes = data[16:19] print struct.unpack('>I', mybytes) --> struct.error: unpack str size does not match format And this: response = (0, 0, data[16], data[17], 6) bytes = array('B', response[:-1]) print struct.unpack('>I', bytes) --> TypeError: Type not compatible with array type And this: print "\nData byte 17:", str.encode(data[17]) --> UnicodeEncodeError: 'ascii' codec can't encode character u'\xff' in position 0: ordinal not in range(128) And I am not sure what to try next. I am completely new to sockets and byte-conversions in Python, so any advice would be helpful :) Thanks, Thomas

  • Explore a COM Object in PHP

    - by shaiss
    What would be the proper way to explode a COM object for debugging? I have a 3rd party function that returns a multilevel object. The documentation is non existant, so I'd like to be able to echo everything out of the object or debug it in Komodo IDE. Komodo just says Object and nothing else. Maybe convert to array? I know some of the existing options such as $com->Status, but there are more variables returned that I'd like to know what they are.

  • How to combine specific column values in an SQL statement

    - by Mehper C. Palavuzlar
    There are two variables in our database called OB and B2B_OB. There are EP codes and each EP may have one of the following 4 combinations: EP OB B2B_OB --- -- ------ 3 X 7 X 11 14 X X What I want to do is to combine the X's in the fetched list so that I can have A or B value for a single EP. My conditions are: IF (OB IS NULL AND B2B_OB IS NULL) THEN TYPE = A IF (OB IS NOT NULL OR B2B_OB IS NOT NULL) THEN TYPE = B The list I want to fetch is like this one: EP TYPE --- ---- 3 B 7 B 11 A 14 B How can I do this in my query? TIA.

  • A tool or framework extension or code snippet for logging the internal state of objects?

    - by George Mauer
    When spiking on how something works or when my unit test behave in an unpredictable manner I usually have to drop into debug mode. 99% of my time in debug mode is spent checking the values of fields on objects to verify its state. I already have log4net set up, it would seem that if I could easily add a line of code to log out the state of objects I could remove most of my need to start up the bulky debugger. The problem is of course that to expose object state implicitly you need to manually override each object's ToString() method. What I would like to be able to do is the ability to do logger.LogState(someObject) and have logged out the object state including at least a formatted list of all the private variables, references (to some arbitrary depth), and collections. Does anyone know a tool/framework/code snippet that can be used to generate a string of the internal state of any object? I could of course write one myself but its a non-trivial problem and I'd prefer something someone has put some thought into.

  • Workflow foundation 4.0 message correlation and error reporting

    - by Lygpt
    I have a workflow service that runs and performs a number of different operations (such as web service calls). If one of these operations fails I call an error reporting web service to notify a seperate system that one of my workflow operations has failed. As the error could be something like the web service being down, I loop and retry this operation until it works. There can be times though when the data I'm passing to this web service is faulty and it needs changing. So I need to be able to hook into this running (but delayed) workflow and change local workflow variables and then re-run the operation. I've looked at message correlation in workflow 4.0 to achieve this but because the delay activity is active in my running workflow instance, any second service call doesn't do anything (it's like the delay activity is blocking any other requests). I've tried setting 'CanCreateInstance' to both true and false but it doesn't help. Thanks!

  • Retrieving related data in the Symfony Admin Generator

    - by bjoern
    I have a problem with the Admin Generator. The Table of Pages have the column sf_guard_user_id. The rest of the table looks as this part of the generator.yml in the line display, list: title: Pages display: [=title, sfGuardUser, views, state, privacy, created_at, updated_at] sort: [created_at, desc] fields: sfGuardUser: { label: Author } created_at: { label: Published, date_format: dd.MM.y } updated_at: { label: Updated, date_format: dd.MM.y } table_method: retrieveUserList Now the sf_guard_user_id is been replaced and the username ist displayed. Don't get me wrong, that works fine. But how can I get other variables from the sfGuarsUser relation? When I only add salt or another variable to display I get this, Unknown record property / related component "salt" on "simplePage" But why?

  • Create a Python User() class that both creates new users and modifies existing users

    - by ensnare
    I'm trying to figure out the best way to create a class that can modify and create new users all in one. This is what I'm thinking: class User(object): def __init__(self,user_id): if user_id == -1 self.new_user = True else: self.new_user = False #fetch all records from db about user_id self._populateUser() def commit(self): if self.new_user: #Do INSERTs else: #Do UPDATEs def delete(self): if self.new_user == False: return False #Delete user code here def _populate(self): #Query self.user_id from database and #set all instance variables, e.g. #self.name = row['name'] def getFullName(self): return self.name #Create a new user >>u = User() >>u.name = 'Jason Martinez' >>u.password = 'linebreak' >>u.commit() >>print u.getFullName() >>Jason Martinez #Update existing user >>u = User(43) >>u.name = 'New Name Here' >>u.commit() >>print u.getFullName() >>New Name Here Is this a logical and clean way to do this? Is there a better way? Thanks.

  • Is there an easy way to get a list of all successful captures from a regex pre-5.10?

    - by Chas. Owens
    I know the right way to do this if I have Perl 5.10 is to use named captures and values %+, but in Perl 5.8.9 and how can I get a list of successful captures? I have come up with two methods that are both just terrible: #you need to list each possible match my @captures = grep { defined } ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10, $11, $12, $13, $14, $15, $16); and #ew, I turned on symbolic references { no strict 'refs'; my @captures = map { defined $+[$_] ? $$_ : () } 1 .. $#+; } There is a third option I have found involving (?{}), but it requires global variables (because the closure happens at compile time) and takes the regex from reasonably clear to ungodly mess. The only alternative I have found is to capture the whole match and then use another set of regexes to get the values I want (actually I build the first regex out of the other regexes because there is no good reason to duplicate the logic).

  • Extract item in a list if Contains returns true

    - by Matt
    I have two lists A and B, at the beginning of my program, they are both filled with information from a database (List A = List B). My program runs, List A is used and modified, List B is left alone. After a while I reload List B with new information from the database, and then do a check with that against List A. foreach (CPlayer player in ListA) if (ListB.Contains(player)) ----- Firstly, the object player is created from a class, its main identifier is player.Name. If the Name is the same, but the other variables are different, would the .Contains still return true? Class CPlayer( public CPlayer (string name) _Name = name At the ---- I need to use the item from ListB that causes the .Contains to return true, how do I do that?

  • Help understanding how to make a bar chart using ggplot2

    - by celenius
    I'm trying to use the bar_geom function of ggplot2, but I can't understand how to use it. I've made a small sample of my code to show what I am trying to do: library(ggplot2) # sample data sampleData = data.frame( v1=c('a','b','c','d','e', 'f','g', 'h', 'i','j'), v2=c(1:10) ) sampleData$Names = data.frame( Names = paste(sampleData$v1, sampleData$v2, sep="") ) sampleData$Values = c(1:10) # make plot x = sampleData$Values y = sampleData$Names qplot( x, y, data = sampleData, geom="bar" ) I want sampleData$Names to be on the x-axis of my graph, labeling each bar and and sampleData$Values to scale the bar height. I want the y-axis to be specified as a range. I realize that I don't understand how ggplot2 functions as this small example does not work, yet my other example is generating a plot but I cannot specify a y-range as it considers the variables to be categorical.

  • Eclipse: How to build an executable jar with external jar?

    - by Ben
    Hi all, I am trying to build an executable jar program which depends on external jar downloaded. In my project, I included them in the build path and can be run and debug within eclipse. When I tried to export it to a jar, I can run the program but I can't when I try to press a button which includes function calls and classes from the external jar. I have edited the environment variables (Windows XP) CLASSPATH to include paths of all the external jar, but it doesn't work. A point to note is that I got compile warnings while exporting my executable jar, but it doesn't show up any description about the warnings. Would someone kindly provide a thorough guide on how to include an external jar program using eclipse? Best regards, KWAN Chiu Yin, Ben

  • what is the difference between "./somescript.sh" and ". ./somescript.sh"

    - by Peter
    This question may sounds silly to you. Today I was following some instructions to install a software in Linux. There was a script that needs to be run first. It set some environment variables. The instruction told me to execute . ./setup.sh, but I made a mistake by executing ./setup.sh. So the env was not set. Finally I noticed this and proceeded. I want to know what exactly is the difference between both? I am completely new to Linux so please be as elaborate as possible.
