  • Javascript How do I force a string + variable to be evaluated as a variable

    - by Craig Rinde
    Im not even sure how to word this and is probably why I am having trouble finding an answer in google. When the code is run currentCardRow will equal 1 therefore it should be cardSelected1 which is what is shown in the console.log. I need it to go a step further because cardSelected1 is a variable and I need it to evaluate show in the console log as Invitation. Invitation is an example of a variable for cardSelected1. I am not sure on what the correct syntax is to make this happen. var currentCardSelected = "cardSelected" + currentCardRow; Thanks for your help!

  • Drupal - db_fetch_array returns NULL for every row

    - by darudude
    I'm using Drupal's db_fetch_array to fetch rows from my db_query. However, every row returned is equal to NULL. Typing the query into PHP myadmin works, so I have no idea whats going on. db_num_rows returns the number of rows as well. Here is the code: if(count($rebuild_ids)) { $ids=implode(",",$rebuild_ids); $type_stmt = "SELECT * from {" . ItemType::$type_table_name . "} where id IN ($ids)"; $new_items=db_query($type_stmt); if(!$new_items || db_num_rows($new_items) == 0) { return; } while($row = db_fetch_array($new_items)); { if ($row!=NULL) { echo "I work!" $game_items[] = $row['id']; ItemInstance::$nid_to_item_type_code[$row['nid']] = $row['id']; } } } However, it never gets into the third if statement (i.e. never echos "I work!") Any ideas?

  • Check if exists, if so, update by 1++, if not insert

    - by Scarface
    Hey guys quick question, I currently have an insert statement $query= "INSERT into new_mail VALUES ('$to1', '0')"; where fields are username, and message_number Currently what I would do to check if the entry exists, is do a select query then check the number of rows with mysql_num_rows (php). If rows==1 then I get the current message_number and set it equal to $row['message_number']++1. Then I update that entry with another query. Is there an easier way to do all this in just mysql with just one query (check if exists, if not insert, if so update message_number, increase by 1)?

  • ActionScript: Using 'in' on protected/private variables?

    - by David Wolever
    Is there any way to mimic the in operator, but testing for the existence of protected or private fields? For example, this: <mx:Script><![CDATA[ public var pub:Boolean = true; protected var prot:Boolean = true; private var priv:Boolean = true; ]]></mx:Script> <mx:creationComplete><![CDATA[ for each (var prop in ["pub", "prot", "priv", "bad"]) trace(prop + ":", prop in this); ]]></mx:creationComplete> Will trace: pub: true prot: false priv: false bad: false When I want to see: pub: true prot: true priv: true bad: false

  • Openbravo Point of Sales: Tax after a certain amount.

    - by Yada
    I'm using Openbravo opensource PoS. It is possible to setup Openbravo PoS to apply a tax only after a certain amount? For example, if the total is less than or equal to $10 then there is no tax, but if the total is over $10 then a 8% tax is applied. Ie: the item costs $10 then the total is $10. If the item is $10.01 then the total is $10.81. I need to setup a rule similar to this. Thanks in advance.

  • How to create a shape acting like a textbox?

    - by subho100
    Please refer this control http://www.charlespetzold.com/blog/2009/10/Using-Text-Outlines-in-Silverlight.html The formattedtext control is a shape which helps to generate the shape of the text with proper geometry. I would like to make this control act like a text box with cursors and features like typing in from keyboard. Right now I use an invisible text box with a formattedtext control to act like that. But the cursor position always creates a problem when the size of the text is not equal to the size of the rendered text as shape. Can anyone please show the way to achieve this.

  • A Tkinter StringVar() Question

    - by Graham
    I would like to create a StringVar() that looks something like this: someText = "The Spanish Inquisition" #Here's a normal variable whose value I will change eventually TkEquivalent = StringVar() #and here's the StringVar() TkEquivalent.set(string(someText)) #and here I set it equal to the normal variable. When someText changes, this variable will too... HOWEVER: TkEquivalent.set("Nobody Expects " + string(someText)) If I do this, the StringVar() will no longer automatically update! How can I include that static text and still have the StringVar() update to reflect changes made to someText? Thanks for your help.

  • How should I get Xcode to link an iOS project that uses a C++ static library

    - by user1681572
    Using Xcode, I've written a Cocoa Touch static library, mainly in C++. It exposes a C interface for the benefit of Objective-C client code. I have a client iOS app that uses it, and everything works and runs as expected, except that I found I needed to include a minimal .cpp file in the client project to get the link to succeed. Otherwise I get C++-related unresolved symbols, e.g. operator new(unsigned long). The above hack is easy and effective, and so I guess I'm not breaking any laws, but is there a proper way to eliminate my linker errors?

  • iphone - Images (slide show) and audio snychronization

    - by Qaiser
    I have 20 images and some audio. I would like to show a single image at a time and change the images at (unequal) intervals. For example, I want to show image 1 for 1.44 seconds and image 2 for 1.67 seconds and so on. Can someone suggest how to go about doing this please? What I have seen are examples that show how to setup an array of images with one field that denotes total time. This causes the images to show for an equal amount of time (each). ... and that not what I am looking for ...

  • C++ How do you set an array of pointers to null in an initialiser list like way?

    - by boredjoe
    I am aware you cannot use an initialiser list for an array. However I have heard of ways that you can set an array of pointers to NULL in a way that is similar to an initialiser list. I am not certain how this is done. I have heard that a pointer is set to NULL by default, though I do not know if this is guaranteed/ in the C++ standard. I am also not sure if initialising through the new operator compared to normal allocation can make a difference too.

  • ActiveRecord and transactionsin between `before_save` and `save`

    - by JP
    I have some logic in before_save whereby (only) when some conditions are met I let the new row be created with special_number equal to the maximum special_number in the database + 1. (If the conditions aren't met then I do something different, so I can't use auto-increments) My worry is that two threads acting on this database at once might pick the same special_number if the second is executed while the first is saving. Is there way to lock the database between before_save and finishing the save, but only in some cases? I know all saves are sent in transactions, will this do the job for me? def before_save if things_are_just_right # -- Issue some kind of lock? # -- self.lock? I have no idea # Pick new special_number new_special = self.class.maximum('special_number') + 1 write_attribute('special_number',new_special) else # No need to lock in this case write_attribute('special_number',some_other_number) end end

  • Breaking out of .emacs script

    - by prosseek
    I use two emacs (Aquamcs and text based emacs) on my Mac. I normally use text based emacs for just editing something, so I don't want to load anything with it. What I came up with is to have the checking code in .emacs to exit/break if it's text based emacs (darwin system but not aquamacs). (when (and (equal system-type 'darwin) (not (boundp 'aquamacs-version))) (exit) ??? (break) ???? ) It seems to work, but I don't know how to break out of .emacs. How to do that? ADDED I just wanted to speed up in loading text based emacs on my mac, and I thought about breaking out as a solution. Based on the helpful answers, I came up with the following code that runs .emacs only when it's not a text based emacs. (setq inhibit-splash-screen t) (unless (null window-system)

  • Retrieving a single Guid in CRM 4.0

    - by user1746560
    I'm new to CRM (version 4.0) and i'm trying to return a 'yearid' guide based on a given year (which is also stored in the entity).So far i've got: public static Guid GetYearID(string yearName) { ICrmService service = CrmServiceFactory.GetCrmService(); // Create the query object. QueryExpression query = new QueryExpression("year"); ColumnSet columns = new ColumnSet(); columns.AddColumn("yearid"); query.ColumnSet = columns; FilterExpression filter = new FilterExpression(); filter.FilterOperator = LogicalOperator.And; filter.AddCondition(new ConditionExpression { AttributeName = "yearName", Operator = ConditionOperator.Equal, Values = new object[] { yearName} }); query.Criteria = filter; } But my questions are: A) What code do in addition to this to actually store the Guid? B) Is using a QueryExpression the most efficient way to do this?

  • R: Change the fields' (slots') values of the class assigning a value to some other field

    - by Max Li
    Assgning a value to one field, how can I make the other fields changing. Consider the following R5 class C<-setRefClass("C", fields=list(a="numeric",b="numeric") , methods=list( seta = function(x){ a<<-x b<<-x+10 cat("The change took place!") } ) # end of the methods list ) # end of the class Now create the instance of the class c<-C$new() This command c$seta(10) will result in that c$a is 10 and c$b is 20. So it actually works, however, I want to achieve this result by the command c$a<-10 (i.e. after that I want c$b to be equal to 20 as defined in the class in the logic of seta() function) How can I do it?

  • Using Linq to filter parents by their children

    - by Nick L
    Having some problems with my Silverlight app (with RIA services) filtering my results. The idea is on the client I set up the EntityQuery and its filters and call load. However this isn't working for me. Heres my code. public void FireQuery(string filterValue) { EntityQuery<Parent> query = m_ParentDomainContext.GetParentQuery(); query = query.Where(p => p.Children.Any(c => c.Name.Contains(filterValue))); m_ParentDomainContext.Load(query, Query_Completed, null); } Compiles just fine, however, runtime I get "Query operator 'Any' is not supported." Exception. Does anyone know of a good way to filter like this? Again, I'm looking for a way to set this up on the client.

  • Can a real number "cover" all integers within its range?

    - by macias
    Is there a guarantee that a real number (float, double, etc) can "cover" all integers within its range? By cover I mean, that for every integer within its range there is such real number that this equality holds: real == int Or in another example, let's say I have the biggest real number which is smaller than given integer. When I add "epsilon" will I get this number equal to given integer or bigger than integer? (I know that among real numbers you should not write comparisons as == for equality, I am simply asking for better understanding subject, not for coding comparisons.)

  • Will PHP script running on top of Apache be faster than C# stand alloun programm doing same thing (s

    - by Ole Jak
    I mean PHP scripts on Apache are oriented for many users to use tham at the same time. So will 1000 requests which came at the (relativly) same time be fully responsed faster than C# .Net programm perfoming algorithm 1000 times in while loop? So we input same data, we perform same algorithm, which is written in a wary same way (respecting language diferencis ofcourse), outputing same data (lat us say saving it to file for tham to be relativly equal) Who will be faster on some 1000 times of performing O(NN) algorithm, in which case (if it is possible) one will owerrun another?

  • In the context of an asp.net website, what's the most efficient way to check whether a User has acce

    - by scaramouch
    I have a webpage that you pass in an id parameter (via a querystring), which it then uses to fetch data from a database. Typically, a user would navigate to this page from another page that lists only those records that the user has access to. However, if they go directly to the page by typing in the URL in the Address Bar, they can effectively view any record they like. Eg. If they were to type something like http://localhost/TestSite/ClientAdmin/ManageLocation.aspx?LocationID=5 into their Address Bar, they can access the database record with the LocationID equal to five - even though they shouldn't have access to it. Now, I could solve this by doing a database check every time the page is loaded to see whether the current user has access to the record they're trying to view. However this doesn't seem very efficient given that in most cases a user won't be trying to access a record that isn't theirs. Does anyone have a better suggestion? Thanks.

  • What does it mean when a Perl method returns a "hashref"?

    - by Uri
    I'm trying to decrypt a Perl code which I'm not familiar with, somehow related to HashRef. I'm using Amazon::S3, but my question is a general Perl question. See the code below: use Amazon::S3; my $s3 = Amazon::S3->new( ... ); my $response = $s3->buckets; Documentation (here) sais, about s3-buckets: Returns undef on error, else HASHREF of results The following line is working for me, but I don't understand why: for $b in ( @ { $response->{buckets} } ) { print "bucket: " . $b->bucket . "\n"; } I'm Puzzled by each operator on the first line. What type exactly are $response, $respone->{bucket}. Looks like the expression within the for is an array, but I don't understand this syntax: @{ ... }?
