• Need to use query column value in nested subquery

  - by Dustin

  It seems I cannot use a column from the parent query in a sub query. How can I refactor this query to get what I need? dbo.func_getRelatedAcnts returns a table of related accounts (all children from a given account). Events and Profiles are related to accounts. SELECT COUNT(r.reg_id) FROM registrations r JOIN profiles p ON (r.reg_frn_pro_id = p.pro_id) JOIN events e ON (r.reg_frn_evt_id = e.evt_id) WHERE evt_frn_acnt_id NOT IN (SELECT * FROM dbo.func_getRelatedAcnts(p.pro_frn_acnt_id))

• Why does initWithFrame have the wrong frame value?

  - by greypoint

  I have a subclass of UIButton called INMenuCard and I am overriding the initWithFrame to include an activity indicator. The menuCard places correctly but any internal reference to "frame" give me "inf,inf,0,0" which means my activityIndicator subview is not placed correctly. What might I be missing? @implementation INMenuCard - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { CGRect innerFrame = CGRectInset(frame, 50.0f, 100.0f); activityIndicator = [[UIActivityIndicatorView alloc] initWithFrame:innerFrame]; activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhite; [self addSubview:activityIndicator]; } return self; } I am instantiating INMenuCard with (debugging shows the CGRect values are correct): CGRect cardFrame = CGRectMake(cardX, cardStartY, cardWidth, cardHeight); INMenuCard *menuCard = [[INMenuCard buttonWithType:UIButtonTypeCustom] initWithFrame:cardFrame]; [theView addSubView:menuCard];

• how to keep the value of a variable in a closure

  - by Florian Fida

  i need to create multiple javascript functions which have a static id inside, so the function itself knows what data to process. Here is some code: (function(){ function log(s){ if(console && console.log) console.log(s); else alert(s); } var i = 10; while (i--){ window.setTimeout(function(){ // i need i to be 10, 9, 8... here not -1 log(i); },500); } })(); The problem ist that i allways gets updated by the loop, and i need to prevent this. Thanks in advance for any help, comments or tips!

• What value to use for include_path in .htaccess

  - by bateman_ap

  Currently in my .htaccess file I am setting include_path such as this: php_value include_path /mnt/webs/mysite/includes:/usr/share/pear However this isn't great if I need to put my sites on a new server as I need to go through a whole load of sites updating each .htaccess. Basically would like a way to basically say "use the folder called includes in the site root (I run a variety of different sites off one server so each .htaccess file and include path will be different). In a related question on here I had someone use: inclue(dirname(__FILE__)."/inc2.php"); But this is in code and might be a bit annoying to do everytime, however should I just use this method and scrap the idea of using .htaccess?

• PHP use function return value as array

  - by Richard Knop

  Why is it that this works: $cacheMatchesNotPlayed = $cache->load('externalData'); $cacheMatchesNotPlayed = $cacheMatchesNotPlayed['matchesNotPlayed']; But this doesn't work: $cacheMatchesNotPlayed = $cache->load('externalData')['matchesNotPlayed']; Is there some reason for it? The second bit is easier to write.

• Assign value to list

  - by Kenneth B

  Hello First and foremost. I'm totally new to "programming" in Excel. I'm trying to make a price calculator, that calculates the price when I use my printer. I have made some lists so it's easy to perform the calculations. Single or duplex: Singlex/Duplex Format: SRA3 / A4 / SRA3 High Gloss The idea is that if I type in an amount of 100 prints, choose SRA3 format on the list, and choose Duplex on the other list. the calculation would look like this: This is how it's calculated: Paper + (print x sides) = Price of the print job Print prices Per page (singlex or duplex): 0,6 Paper format and price: A4 reg. paper: 0,2 SRA3 High Gloss: 1,25 SRA3 reg. paper: 1 Does anyone know about this???

  Hello all I have a webservice that returns an XML like this: <?xml version="1.0" encoding="UTF-8"?> <contractInformation> <contract> <idContract type="int">87191827</idContract> <region type="varchar">null</region> <dueDate type="varchar">null</dueDate> <contactName type="varchar">John Smith</contactName> </contract> </contractInformation> I want to empty every tag that contains the string null, so it would look like this: <?xml version="1.0" encoding="UTF-8"?> <contractInformation> <contract> <idContract type="int">87191827</idContract> <region type="varchar"/> <dueDate type="varchar"/> <contactName type="varchar">John Smith</contactName> </contract> </contractInformation> How do I accomplish that by using XSLT?

• Select all rows where there is not a specific value in a different table

  - by JMC Creative

  This is a wordpress installation, but I think the question is more of a general sql question. First off, my sql skills are not great (I don't even know if I'm following the correct format for illustrating the db). I've got two tables: wp_posts : ID (pk) | post_name | ... ---------------------------- 45 | "Hello" 91 | "Funny" 16 | "Wheat" wp_postmeta : post_id (fk) | meta_key | meta_value | ... ------------------------------------------------ 45 | "_edit_lock" | 5789789834 45 | "fizzbizz" | "foobar" 91 | "_something" | "teve" 16 | "_edit_lock" | 8798756 I would to select all rows in wp_posts where there is NO corresponding row in wp_postmeta where meta_key = "fizzbizz" I originally had this query, but someone pointed out that it would not retrive ID = '16' in the above case. How would I correctly write the query? $pageposts = $wpdb->get_results(" SELECT * FROM wp_posts p JOIN wp_postmeta m ON p.ID = m.post_id WHERE m.meta_key <> 'fizzbizz' ORDER BY p.post_date DESC; ");

• In parallel.for share value more then one.

  - by user347918

  Here is problem. long sum = 0; Parallel.For(1, 10000, y => { sum1 += y;} ); Solution is .. Parallel.For<int>(0, result.Count, () => 0, (i, loop, subtotal) => { subtotal += result[i]; return subtotal; }, (x) => Interlocked.Add(ref sum, x) ); if there are two parameters in this code. For example long sum1 = 0; long sum2 = 0; Parallel.For(1, 10000, y => { sum1 += y; sum2=sum1*y; } ); what will we do ? i am guessing that have to use array ! int[] s=new int[2]; Parallel.For<int[]>(0, result.Count, () => s, (i, loop, subtotal) => { subtotal[0] += result[i]; subtotal[1] -= result[i]; return subtotal; }, (x) => Interlocked.Add(ref sum1, x[0]) //but how about sum1 i tried several way but it doesn't work. //for example like that //(x[0])=> Interlocked.Add (ref sum1, x[0]) //(x[1])=> Interlocked.Add (ref sum2, x[1]));

• Find the right value in recursive array

  - by fire

  I have an array with multiple sub-arrays like this: Array ( [0] => Array ( [Page_ID] => 1 [Page_Parent_ID] => 0 [Page_Title] => Overview [Page_URL] => overview [Page_Type] => content [Page_Order] => 1 ) [1] => Array ( [0] => Array ( [Page_ID] => 2 [Page_Parent_ID] => 1 [Page_Title] => Team [Page_URL] => overview/team [Page_Type] => content [Page_Order] => 1 ) ) [2] => Array ( [Page_ID] => 3 [Page_Parent_ID] => 0 [Page_Title] => Funds [Page_URL] => funds [Page_Type] => content [Page_Order] => 2 ) [3] => Array ( [0] => Array ( [Page_ID] => 4 [Page_Parent_ID] => 3 [Page_Title] => Strategy [Page_URL] => funds/strategy [Page_Type] => content [Page_Order] => 1 ) [1] => Array ( [0] => Array ( [Page_ID] => 7 [Page_Parent_ID] => 4 [Page_Title] => A Class Fund [Page_URL] => funds/strategy/a-class-fund [Page_Type] => content [Page_Order] => 1 ) [1] => Array ( [0] => Array ( [Page_ID] => 10 [Page_Parent_ID] => 7 [Page_Title] => Information [Page_URL] => funds/strategy/a-class-fund/information [Page_Type] => content [Page_Order] => 1 ) [1] => Array ( [Page_ID] => 11 [Page_Parent_ID] => 7 [Page_Title] => Fund Data [Page_URL] => funds/strategy/a-class-fund/fund-data [Page_Type] => content [Page_Order] => 2 ) ) [2] => Array ( [Page_ID] => 8 [Page_Parent_ID] => 4 [Page_Title] => B Class Fund [Page_URL] => funds/strategy/b-class-fund [Page_Type] => content [Page_Order] => 2 ) I need a function to find the right Page_URL so if you know the $url is "funds/strategy/a-class-fund" I need to pass that to a function that returns a single array result (which would be the Page_ID = 7 array in this example). Having a bit of a stupid day, any help would be appreciated!

  I have written a snippet of code in javascript, for a prompt to appear when clicked.

• Webservice parameter value encoding

  - by dnolan

  We have a webservice created in WCF and presenting itself as a basicHttpBinding. One of the parameters is a string which takes an xml string. Looking at the soap the client generates to send to the webservice, the xml is encoded, with all < and swapped into < and >. My question is, is this all that is encoded, or has the parameter been run through HtmlEncode so that other entities would be swapped also? The reason I ask is we are submitting with our client to a 3rd party webservice now and they would like to know the details on what is encoded.

• How to fetch managed objects sorted by calculated value

  - by Marcin Zbijowski

  Hello, I'm working on the app that uses CoreData. There is location entity that holds latitude and longitude values. I'd like to fetch those entities sorted by distance to the user's location. I tried to set sort descriptor to distance formula sqrt ((x1 - x2)^2 + (y1 - y2)^2) but it fails with exception "... keypath ... not found in entity". NSString *distanceFormula = [NSString stringWithFormat:@"sqrt(((latitude - %f) * (latitude - %f)) + ((longitude - %f) * (longitude - %f)))", location.coordinate.latitude, location.coordinate.latitude, location.coordinate.longitude, location.coordinate.longitude]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:distanceFormula ascending:YES]; [fetchRequest setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]]; NSError *error; NSArray *result = [[self managedObjectContext] executeFetchRequest:fetchRequest error:&error]; I'd like to fetch already sorted objects rather then fetch them all and then sort in the code. Any tips appreciated.

• How do I use grep to extract a specific field value from lines

  - by Stormshadow

  I have lines in a file which look like the following ....... DisplayName="john" .......... where .... represents variable number of other fields. Using the following grep command, I am able to extract all the lines which have a valid 'DisplayName' field grep DisplayName="[0-9A-Za-z[:space:]]*" e:\test However, I wish to extract just the name (ie "john") from each line instead of the whole line which is returned by grep. I tried pipelining the output to the cut command but it does not accept string delimiters.

• Null Value Statement

  Hi All, I have created a table called table1 and it has 4 columns named Name,ID,Description and Date. I have created them like Name varchar(50) null, ID int null,Description varchar(50) null, Date datetime null I have inserted a record into the table1 having ID and Description values. So Now my table1 looks like this: Name ID Description Date Null 1 First Null One of them asked me to modify the table such a way that The columns Name and Date should have Null values instead of Text Null. I don't know what is the difference between those I mean can anyone explain me the difference between these select statements: SELECT * FROM TABLE1 WHERE NAME IS NULL SELECT * FROM TABLE1 WHERE NAME = 'NULL' SELECT * FROM TABLE1 WHERE NAME = ' ' Can anyone explain me?

• getting the value of a filter at an arbitrary time

  - by Andiih

  Context: I'm trying to improve the values returned by the iPhone CLLocationManager, although this is a more generally applicable problem. The key is that CLLocationManger returns data on current velocity as and when it feels like it, rather than at a fixed sample rate. I'd like to use a feedback equation to improve accuracy v=(k*v)+(1-k)*currentVelocity where currentVelocity is the speed returned by didUpdateToLocation:fromLocation: and v is the output velocity (and also used for the feedback element). Because of the "as and when" nature of didUpdateToLocation:fromLocation: I could calculate the time interval since it was last called, and do something like for (i=0;i<timeintervalsincelastcalled;i++) v=(k*v)+(1-k)*currentVelocity which would work, but is wasteful of cycles. Especially as I probably want timeintervalsincelastcalled to be measured as 10ths of a second. Is there a way to solve this without the loop ? i.e. rework (integrate?) the formula so I put an interval into the equation and get the same answer as I would have by iteration ?

• Getting the value from an array in the model in rails

  - by slythic

  Hi all, I have a relatively simple problem. I have a model named Item which I've added a status field. The status field will only have two options (Lost or Found). So I created the following array in my Item model: STATUS = [ [1, "Lost"], [2, "Found"]] In my form view I added the following code which works great: <%= collection_select :item, :status, Item::STATUS, :first, :last, {:include_blank => 'Select status'} %> This stores the numeric id (1 or 2) of the status in the database. However, in my show view I can't figure out how to convert from the numeric id (again, 1 or 2) to the text equivalent of Lost or Found. Any ideas on how to get this to work? Is there a better way to go about this? Many thanks, Tony

• How to have NHibernate persist a String.Empty property value as NULL

  - by Todd

  I have a fairly simple class that I want to save to SQL Server via NHibernate (w/ Fluent mappings). The class is made up mostly of optional string fields. My problem is I default the class fields to string.empty to avoid NullRefExceptions and when NHibernate saves the row to the database each column contains an empty string instead of null. Question: Is there a way for me to get NHibernate to automatically save null when the string property is an empty string? Or do I need to litter my code with if (string.empty) checks?
