    - by udaya

How to set the maximum number of data that a word page can contain ,,,, I want only 20 datas in a single page This is the coding i use to export the data to pdf In mysql_table.php the table for the pdf document is be generated <?php require('mysql_table.php'); class PDF extends PDF_MySQL_Table { function Header() { //Title $this->SetFont('Arial','',18); $this->Cell(0,6,'Country details',0,1,'C'); $this->Ln(10); parent::Header(); } } //Connect to database mysql_connect('localhost','root',''); mysql_select_db('cms'); $pdf=new PDF(); $pdf->AddPage(); //First table: put all columns automatically $pdf->Table("SELECT (SELECT COUNT(*) FROM tblentercountry t2 WHERE t2.dbName <= t1.dbName and dbIsDelete='0') AS SLNO ,dbName as Namee,t3.dbCountry as Country,t4.dbState as State,t5.dbTown as Town FROM tblentercountry t1 join tablecountry as t3, tablestate as t4, tabletown as t5 where t1.dbIsDelete='0' and t1.dbCountryId=t3.dbCountryId and t1.dbStateId=t4.dbStateId and t1.dbTownId=t5.dbTownId order by dbName"); $pdf->AddPage(); //Second table: specify 3 columns $pdf->AddCol('rank',20,'','C'); $pdf->AddCol('name',20,'tablecountry'); $pdf->AddCol('pop',20,'Pop (2001)','R'); $prop=array('HeaderColor'=>array(255,150,100), 'color1'=>array(210,245,255), 'color2'=>array(255,255,210), 'padding'=>2); //$pdf->Table('select dbCountry,dbCountryId from tablecountry limit 0,10',$prop); $pdf->Output(); ?> How to limit the number of datas in a page

  • How to create an XML document from a .NET object?

    - by JL
    I have the following variable that accepts a file name: var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); I would like to change it so that I can pass in an object. I don't want to have to serialize the object to file first. Is this possible? Update: My original intentions were to take an xml document, merge some xslt (stored in a file), then output and return html... like this: public string TransformXml(string xmlFileName, string xslFileName) { var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); var xslt = new System.Xml.Xsl.XslCompiledTransform(); xslt.Load(xslFileName); var stm = new MemoryStream(); xslt.Transform(xd, null, stm); stm.Position = 1; var sr = new StreamReader(stm); xtr.Close(); return sr.ReadToEnd(); } In the above code I am reading in the xml from a file. Now what I would like to do is just work with the object, before it was serialized to the file. So let me illustrate my problem using code public string TransformXMLFromObject(myObjType myobj , string xsltFileName) { // Notice the xslt stays the same. // Its in these next few lines that I can't figure out how to load the xml document (xd) from an object, and not from a file.... var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); }

  • Weird URL parse issue. (Android)

    - by Tarmon
    I am attempting to parse in a URL to a KML file from maps.google.com. When I try and use this link: http://maps.google.com/maps/ms?ie=UTF8&hl=en&msa=0&msid=112748174025829638330.000483ad6315714cc941d&z=13&output=kml` I am unable to overlay this KML file on my MapView. If I were to take the KML file that I get from following this link and upload it to my Dropbox it will work just fine. I think there may be something about the URL from Google that it doesn't like? Link from dropbox: http://dl.dropbox.com/u/1037184/Blue_original.kml Also it would be better if we could just save these KML files locally and pass them in the same way but I can't figure out a way to do this. Here is the code I am using: Intent mapIntent = new Intent(Intent.ACTION_VIEW); Uri uri1 = Uri.parse("geo:0,0?q=http://code.google.com/apis/kml/ documentation/KML_Samples.kml"); mapIntent.setData(uri1); startActivity(Intent.createChooser(mapIntent, "Test")); The URL used in this example also works. So to recap: I am curious as to why some URLs work and others don't. Is there a way to place this KML file locally on the device and pass it to a Uri object? Any other suggestions? Thanks, Rob

  • PHP Streaming CSV always adds UTF-8 BOM

    - by Mustafa Ashurex
    The following code gets a 'report line' as an array and uses fputcsv to tranform it into CSV. Everything is working great except for the fact that regardless of the charset I use, it is putting a UTF-8 bom at the beginning of the file. This is exceptionally annoying because A) I am specifying iso and B) We have lots of users using tools that show the UTF-8 bom as characters of garbage. I have even tried writing the results to a string, stripping the UTF-8 BOM and then echo'ing it out and still get it. Is it possible that the issue resides with Apache? If I change the fopen to a local file it writes it just fine without the UTF-8 BOM. header("Content-type: text/csv; charset=iso-8859-1"); header("Cache-Control: no-store, no-cache"); header("Content-Disposition: attachment; filename=\"report.csv\""); $outstream = fopen("php://output",'w'); for($i = 0; $i < $report-rowCount; $i++) { fputcsv($outstream, $report-getTaxMatrixLineValues($i), ',', '"'); } fclose($outstream); exit;

  • What's the largest (most complex) PHP algorithm ever implemented in a single monolithic PHP script?

    - by Alex R
    I'm working on a tool which converts PHP code to Scala. As one of the finishing touches, I'm in need of a really good (er, somewhat biased) benchmark. By dumb luck my first benchmark attempt was with some code which uses bcmath extensively, which unfortunately is 1000x slower in Java, making the Scala code 22x slower overall than the original PHP. So I'm looking for some meaningful PHP benchmark with the following characteristics: The source needs to be in a single file. I need it to be simple to setup - no databases, hard-to-find input files, etc. Simple text input and output preferred. It should not use features that are slow in Java (BigInteger, trigonometric functions, etc). It should not use exoteric or dynamic PHP functions (e.g. no "eval" or "variable vars"). It should not over-rely on built-in libraries, e.g. MD5, crypt, etc. It should not be I/O bound. A CPU-bound memory-hungry algorithm is preferred. Basically, intensive OO operations, integer and string manipulation, recursion, etc would be great. Thanks

  • dynamic check_box using field_for in rails

    - by Craig Whitley
    I have a many-to-many relationship with a link box, and I want to pull those models together into one form so I can update from the same page. I'm really struggling with getting the check_box to even show all the elements of my array - I've scoured the net and been working on this literally all day, and I'm finding it difficult to apply the information I'm reading to my problem. I'm also extremely new to RoR and I've been following a bit of an outdated video tutorial (pre 2.0) so apologies for my code. So far, I've got it to output only one key pair in the array (the last one) - although outside the form, the code used in the tutorial works exactly how it should. Thats of little use though! Host is the model for which the main form is for, and Billing is the outside model that I'm trying to add to the form. This is the code that works outside of the form from the tutorial: <% for billing in @billings -%> <%= check_box_tag('billing_title[]', billing.id, @host.billings.collect {|obj| obj.id}.include?(billing.id))%> <%= billing.title %><br /> <% end -%> I just need to know how to make it work inside the form. This is the aforementioned code that only retrieves the last array keypair after looping through them: <% f.fields_for :billings do |obj| %><br /> <%= check_box_tag('billing_title[]', billing.id, @billings.collect {|obj| obj.id}.include?(billing.id))%> <%= billing.title %><br /> <% end %> The debug(@billings) : --- - !ruby/object:Billing attributes: title: Every Month id: "1" attributes_cache: {} - !ruby/object:Billing attributes: title: 12 Months id: "2" attributes_cache: {} - !ruby/object:Billing attributes: title: 6 Months id: "5" attributes_cache: {} Any help really appreciated.

  • objective-c 2.0 properties and 'retain'

    - by Adam
    Stupid question, but why do we need to use 'retain' when declaring a property? Doesn't it get retained anyway when it's assigned something? Looking at this example, it seems that an object is automatically retained when alloc'ed, so what's the point? #import "Fraction.h" #import <stdio.h> int main( int argc, const char *argv[] ) { Fraction *frac1 = [[Fraction alloc] init]; Fraction *frac2 = [[Fraction alloc] init]; // print current counts printf( "Fraction 1 retain count: %i\n", [frac1 retainCount] ); printf( "Fraction 2 retain count: %i\n", [frac2 retainCount] ); // increment them [frac1 retain]; // 2 [frac1 retain]; // 3 [frac2 retain]; // 2 // print current counts printf( "Fraction 1 retain count: %i\n", [frac1 retainCount] ); printf( "Fraction 2 retain count: %i\n", [frac2 retainCount] ); // decrement [frac1 release]; // 2 [frac2 release]; // 1 // print current counts printf( "Fraction 1 retain count: %i\n", [frac1 retainCount] ); printf( "Fraction 2 retain count: %i\n", [frac2 retainCount] ); // release them until they dealloc themselves [frac1 release]; // 1 [frac1 release]; // 0 [frac2 release]; // 0 ¦output Fraction 1 retain count: 1 Fraction 2 retain count: 1 Fraction 1 retain count: 3 Fraction 2 retain count: 2 Fraction 1 retain count: 2 Fraction 2 retain count: 1 Deallocing fraction Deallocing fraction This is driving me crazy!

  • Wordpress Custom Posts

    - by codedude
    I'm having a serious problem with custom post types in Wordpress. I made a post type called "Sermons". I then add a meta box with some text fields and echo out the results onto the web page. But here's my problem. The first time when you add a "Sermon", it works fine and the meta box fields output correctly. However, when I try to edit one of the meta boxes and do not edit the others, (say after I closed the web browser I remembered that I needed to add something to the fields,) the fields that were not edited become blank and the content in them is erased...not good at all. So, just to simplify this: the first time the meta boxes are filled they work fine. However, when editing the post for the second time, the fields that are not filled out, but left as they were, become blank upon saving the post. Help...I'm not too much of a developer so I'm not exactly sure how to fix this...(it was hard enough getting the meta fields to work.) (If you want the actual code used, please tell me and I will add is somewhere.

  • using the window object for accessing global user defined objects and using text within html for cre

    - by timpone
    I don't do very much jquery / javascript but wanted to ask for some advice on the following piece. I have tried to cut out as much as possible. Most of this was semi-inherited code with catching a bunch of events just hardcoded in. I'd like to generalized them more by putting the object name in the html and accessing via jquery on processing (by_date, by_popularity). I retriev as string and access the object via window[current_obj]. Is this a good way to do this or am I missing something? Are there preferable ways to introduce specificity. thanks for any advice. <script> var by_date={}; by_date.current_page=1; by_date.per_page=4; var by_popularity={}; by_popularity.current_page=1; by_popularity.per_page=4; $(function(){ $('.previous.active').live('click',function(){ window[current_obj].current_page--; process(window[current_obj]); }); }); function process(game_obj){ //will process and output new items here } </script> <div class="otherContainer"> <a class='previous active'>Prev</a><div style="display:none;">by_date</div> | <a class='next'>Next</a><div style="display:none;">by_date</div> </div> <div class="topPrevNextContainer"> <a class='previous active'>Prev</a><div style="display:none;">by_popularity</div> | <a class='next'>Next</a><div style="display:none;">by_popularity</div> </div>

  • Django's post_save signal behaves weirdly with models using multi-table inheritance

    - by hekevintran
    Django's post_save signal behaves weirdly with models using multi-table inheritance I am noticing an odd behavior in the way Django's post_save signal works when using a model that has multi-table inheritance. I have these two models: class Animal(models.Model): category = models.CharField(max_length=20) class Dog(Animal): color = models.CharField(max_length=10) I have a post save callback called echo_category: def echo_category(sender, **kwargs): print "category: '%s'" % kwargs['instance'].category post_save.connect(echo_category, sender=Dog) I have this fixture: [ { "pk": 1, "model": "animal.animal", "fields": { "category": "omnivore" } }, { "pk": 1, "model": "animal.dog", "fields": { "color": "brown" } } ] In every part of the program except for in the post_save callback the following is true: from animal.models import Dog Dog.objects.get(pk=1).category == u'omnivore' # True When I run syncdb and the fixture is installed, the echo_category function is run. The output from syncdb is: $ python manage.py syncdb --noinput Installing json fixture 'initial_data' from '~/my_proj/animal/fixtures'. category: '' Installed 2 object(s) from 1 fixture(s) The weird thing here is that the dog object's category attribute is an empty string. Why is it not 'omnivore' like it is everywhere else? As a temporary (hopefully) workaround I reload the object from the database in the post_save callback: def echo_category(sender, **kwargs): instance = kwargs['instance'] instance = sender.objects.get(pk=instance.pk) print "category: '%s'" % instance.category post_save.connect(echo_category, sender=Dog) This works but it is not something I like because I must remember to do it when the model inherits from another model and it must hit the database again. The other weird thing is that I must do instance.pk to get the primary key. The normal 'id' attribute does not work (I cannot use instance.id). I do not know why this is. Maybe this is related to the reason why the category attribute is not doing the right thing?

  • Beginner SQL question: querying gold and silver tag badges in Stack Exchange Data Explorer

    - by polygenelubricants
    I'm using the Stack Exchange Data Explorer to learn SQL, but I think the fundamentals of the question is applicable to other databases. I'm trying to query the Badges table, which according to Stexdex (that's what I'm going to call it from now on) has the following schema: Badges Id UserId Name Date This works well for badges like [Epic] and [Legendary] which have unique names, but the silver and gold tag-specific badges seems to be mixed in together by having the same exact name. Here's an example query I wrote for [mysql] tag: SELECT UserId as [User Link], Date FROM Badges Where Name = 'mysql' Order By Date ASC The (slightly annotated) output is: as seen on stexdex: User Link Date --------------- ------------------- // all for silver except where noted Bill Karwin 2009-02-20 11:00:25 Quassnoi 2009-06-01 10:00:16 Greg 2009-10-22 10:00:25 Quassnoi 2009-10-31 10:00:24 // for gold Bill Karwin 2009-11-23 11:00:30 // for gold cletus 2010-01-01 11:00:23 OMG Ponies 2010-01-03 11:00:48 Pascal MARTIN 2010-02-17 11:00:29 Mark Byers 2010-04-07 10:00:35 Daniel Vassallo 2010-05-14 10:00:38 This is consistent with the current list of silver and gold earners at the moment of this writing, but to speak in more timeless terms, as of the end of May 2010 only 2 users have earned the gold [mysql] tag: Quassnoi and Bill Karwin, as evidenced in the above result by their names being the only ones that appear twice. So this is the way I understand it: The first time an Id appears (in chronological order) is for the silver badge The second time is for the gold Now, the above result mixes the silver and gold entries together. My questions are: Is this a typical design, or are there much friendlier schema/normalization/whatever you call it? In the current design, how would you query the silver and gold badges separately? GROUP BY Id and picking the min/max or first/second by the Date somehow? How can you write a query that lists all the silver badges first then all the gold badges next? Imagine also that the "real" query may be more complicated, i.e. not just listing by date. How would you write it so that it doesn't have too many repetition between the silver and gold subqueries? Is it perhaps more typical to do two totally separate queries instead? What is this idiom called? A row "partitioning" query to put them into "buckets" or something?

  • How can I get the dimensions of a drawn string without padding?

    - by Dan Herbert
    I'm trying to create an image with some text on it and I want the image's size to match the size of the rendered text. When I use System.Windows.Forms.TextRenderer.MeasureText(...) to measure the text, I get dimensions that include font padding. When the text is rendered, it seems to use the same padding. Is there any way to determine the size of a string of text and then render it without any padding? This is the code I've tried: // Measure the text dimensions var text = "Hello World"; var fontFamily = new Font("Arial", 30, FontStyle.Regular); var textColor = new SolidBrush(Color.Black); Size textSize = TextRenderer.MeasureText(text, fontFamily, Size.Empty, TextFormatFlags.NoPadding); // Render the text with the given dimensions Bitmap bmp = new Bitmap(textSize.Width, textSize.Height); Graphics g = Graphics.FromImage(bmp); g.TextRenderingHint = TextRenderingHint.AntiAliasGridFit; g.DrawString(text, fontFamily, textColor, new PointF(0, 0)); bmp.Save("output.png", ImageFormat.Png); This is what currently gets rendered out: This is what I want to render: I also looked into Graphics.MeasureString(...), but that can only be used on an existing Graphics object. I want to know the size before creating the image. Also, calling Graphics.MeasureString(...) returns the same dimensions, so it doesn't help me any.

  • What is the exact difference between MEM_RESERVE and MEM_COMMIT states?

    - by pj4533
    As I understand it MEM_RESERVE is actually 'free' memory, ie available to be used by my process, but just hasn't been allocated yet? Or it was previously allocated, but had since been freed? Specifically, see in my !address output below how I am nearly out of virtual address space (99900 KB free, 2307872 as MEM_PRIVATE. But the states shows that 44.75% of that is actually MEM_RESERVE.

  • Javascript/PHP and timezones

    - by James
    Hi, I'd like to be able to guess the user's timezone offset and whether or not daylight savings is being applied. Currently, the most definitive code that I've found for this is here: http://www.michaelapproved.com/articles/daylight-saving-time-dst-detect/ So this gives me the offset along with the DST indicator. Now, I want to use these in my PHP scripts in order to ouput the local date/time for the user....but what's best for this? I figure I have 2 options: a) Pick a random timezone which has the same offset and DST setting from the output of timezone_abbreviations_list(). Then call date_timezone_set() with this in order to apply the correct treatment to the time. b) Continue treating the date as UTC but just do some timestamp addition to add the appropriate number of hours on. My feeling is that option B is the best way. The reason for this is that with A, I could be using a timezone which although correct in terms of offset/dst, may have some obscur rules in place behind the scene that could give surprising results (I don't know of any but nonetheless I don't think I can rule it out). I'd then re-check the timezone using Javascript at the start of each session in order to capture when either the user's timezone changes (very unlikely) or they pass in to the DST period. Sorry for the brain dump - I'm really just after some sort of reassurance that the approaches above are valid. Thanks, James.

  • Sweave/R - Automatically generating an appendix that contains all the model summaries/plots/data pro

    - by John Horton
    I like the idea of making research available at multiple levels of detail i.e., abstract for the casually curious, full text for the more interested, and finally the data and code for those working in the same area/trying to reproduce your results. In between the actual text and the data/code level, I'd like to insert another layer. Namely, I'd like to create a kind of automatically generated appendix that contains the full regression output, diagnostic plots, exploratory graphs data profiles etc. from the analysis, regardless of whether those plots/regressions etc. made it into the final paper. One idea I had was to write a script that would examine the .Rnw file and automatically: Profile all data sets that are loaded (sort of like the Hmisc(?) package) Summarize all regressions - i.e., run summary(model) for all models Present all plots (regardless of whether they made it in the final version) The idea is to make this kind of a low-effort, push-button sort of thing as opposed to a formal appendix written like the rest of a paper. What I'm looking for is some ideas on how to do this in R in a relatively simple way. My hunch is that there is some way of going through the namespace, figuring out what something is and then dumping into a PDF. Thoughts? Does something like this already exist?

  • Cleaner/more effective way to use modulus and creating columned lists

    I currently have a list (<ul>) of people that I have divided up into two columns.

  • cakephp secure link using html helper link method..

    - by Aaron
    What's the best way in cakephp to extend the html-link function so that I can tell it to output a secure(https) link? Right now, I've added my own secure_link function to app_helpers that's basically a copy of the link function but adding a https to the beginning. But it seems like there should be a better way of overriding the html-link method so that I can specify a secure option. http://groups.google.com/group/cake-php/browse%5Fthread/thread/e801b31cd3db809a I also started a thread on the google groups and someone suggested doing something like $html->link('my account', array('base' => 'https://', 'controller' => 'users')); but I couldn't get that working. Just to add, this is what is outputted when I have the above code. <a href="/users/index/base:https:/">my account</a> I think there's a bug in the cake/libs/router.php on line 850. There's a keyword 'bare' and I think it should be 'base' Though changing it to base doesn't seem to fix it. From what I gather, it's telling it to exclude those keys that are passed in so that they don't get included as parameters. But I'm puzzled as to why it's a 'bare' keyword and the only reason I can come up with is that it's a type.

  • Disassembling with python - no easy solution?

    - by Abc4599
    Hi, I'm trying to create a python script that will disassemble a binary (a Windows exe to be precise) and analyze its code. I need the ability to take a certain buffer, and extract some sort of struct containing information about the instructions in it. I've worked with libdisasm in C before, and I found it's interface quite intuitive and comfortable. The problem is, its Python interface is available only through SWIG, and I can't get it to compile properly under Windows. At the availability aspect, diStorm provides a nice out-of-the-box interface, but it provides only the Mnemonic of each instruction, and not a binary struct with enumerations defining instruction type and what not. This is quite uncomfortable for my purpose, and will require a lot of what I see as spent time wrapping the interface to make it fit my needs. I've also looked at BeaEngine, which does in fact provide the output I need, a struct with binary info concerning each instruction, but its interface is really odd and counter-intuitive, and it crashes pretty much instantly when provided with wrong arguments. The CTypes sort of ultimate-death-to-your-python crashes. So, I'd be happy to hear about other solutions, which are a little less time consuming than messing around with djgcc or mingw to make SWIGed libdisasm, or writing an OOP wrapper for diStorm. If anyone has some guidance as to how to compile SWIGed libdisasm, or better yet, a compiled binary (pyd or dll+py), I'd love to hear/have it. :) Thanks ahead.

  • Ruby on Rails: how to get error messages from a child resource displayed?

    - by randombits
    I'm having a difficult time understanding how to get Rails to show explicitly the error messages that a child resource is failing on when I render an XML template. Hypothetically, I have the following classes: class School < ActiveRecord::Base has_many :students validates_associated :students end class Student < ActiveRecord::Base belongs_to :school validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :message => "You must supply a valid email" end Now, in the controller, let's say we want to build a trivial API to allow us to add a new School with a student in it (again, I said, it's a terrible example, but plays its role for the purpose of the question) class SchoolsController < ApplicationController def create @school = School.new @student = school.students.build @student.email = "bad@email" respond_to do |format| if @school.save # some code else format.xml { render :xml => @school.errors, :status => :unprocessable_entity } end end end end Now the validation is working just fine, things die because the email doesn't match the regex that's set in the validates_format_of method in the Student class. However the output I get is the following: <?xml version="1.0" encoding="UTF-8"?> <errors> <error>Students is invalid</error> </errors> I want the more meaningful error message that I set above with validates_format_of to show up. Meaning, I want it to say: <error>You must supply a valid email</error> What am I doing wrong for that not to show up?

  • Need to add totals of select list, and subtract if taken away

    - by jeremy
    This is the code I am using to calculate the sum of two values (example below) http://www.healthybrighton.co.uk/wse/node/1841 This works to a degree. It will add the two together but only if #edit-submitted-test is selected first, and even then it will show NaN until I select #edit-submitted-test-1. I want it to calculate the sum of the fields and show the amount live, i.e. the value of edit-submitted-test-1 will show 500, then if i select another field it will update to 1000. If i take one selection away it will then subtract it and will be back to 500. Any ideas would be helpful thanks! Drupal.behaviors.bookingForm = function (context) { // some debugging here, remove when you're finished console.log('[bookingForm] started.'); // get number of travelers and multiply it by 100 function recalculateTotal() { var count = $('#edit-submitted-test').val(); count = parseFloat( count ); var cost = $('#edit-submitted-test-1').val(); cost = parseFloat( cost ); $('#edit-submitted-total').val( count + cost ); } // run recalculateTotal every time user enters a new value var fieldCount = $('#edit-submitted-test'); var fieldCount = $('#edit-submitted-test-1'); fieldCount.change( recalculateTotal ); // etc ... }; EDIT This is all working beautiful, however I now want to add all the values together, and automatically update a total cost field that is the sum of a the added field with code above and field with value passed from previous page. I did this where accomcost is the field that is added together, but the total cost field does update, but not automatically, it is always one selection behind. i.e. If i select options and accomodation cost updates to £900, total cost remains empty. If i then change the selection and the accomodation updates to £300, the total cost updates to the previous selection of £900. Any help on this one Felix? ;) thanks. var accomcost = $('#edit-submitted-accomodation-cost').val(); accomcost = accomcost ? parseFloat(accomcost) : 0; var coursescost = $('#edit-submitted-courses-cost-2').val(); coursescost = coursescost ? parseFloat(coursescost) : 0; $('#edit-submitted-accomodation-cost').val( w1 + w2 + w3 + w4 + w5 + w6 + w7 + w8 + w9 + w10 + w11 + w12 + w13 + w14 + w15 + w16 + w17 + w18 + w19 + w20 + w21 + w22 + w23 + w24 + w25 + w26 + w27 + w28 + w29 + w30 ); $('#edit-submitted-total-cost').val( accomcost + coursescost ); var fieldCount = $('#edit-submitted-accomodation-cost, #edit-submitted-courses-cost-2') .change( recalculateTotal );

  • Printing Arrays from Structs

    - by Carlll
    I've been stumped for a few hours on an exercise where I must use functions to build up an array inside a struct and print it. In my current program, it compiles but crashes upon running. #define LIM 10 typedef char letters[LIM]; typedef struct { int counter; letters words[LIM]; } foo; int main(int argc, char **argv){ foo apara; structtest(apara, LIM); print_struct(apara); } int structtest(foo *p, int limit){ p->counter = 0; int i =0; for(i; i< limit ;i++){ strcpy(p->words[p->counter], "x"); //only filling arrays with 'x' as an example p->counter ++; } return; I do believe it's due to my incorrect usage/combination of pointers. I've tried adjusting them, but either an 'incompatible types' error is produced, or the array is seemingly blank } void print_struct(foo p){ printf(p.words); } I haven't made it successfully up to the print_struct stage, but I'm unsure whether p.words is the correct item to be calling. In the output, I would expect the function to return an array of x's. I apologize in advance if I've made some sort of grievous "I should already know this" C mistake. Thanks for your help.

  • Exponential regression : p-value and F significance

    - by Saravanan K
    I am new to statistics. I have a set of independent data and dependent data (X,Y), where I would like to do an exponential regression to obtain its p-value and significant F (already obtained R2 and also the coefficients through mathematical calculation). What is the natural evolution from the (X,Y) data to mathematically calculate those variables. Spent a week on the internet to study this but unable to find the right answer. Often an exponential data, y=be^(mx) will be converted first to a linear data, ln y = mx + ln b . Then a linear regression will done on the converted data, obtaining its p-value etc. Assume we use a statistical tool such as Excel's Analysis ToolPak: Data Analysis : Regression, it will produce a result such as below, I believe the p-value and Significant F value is representing the converted linear data and not the original exponential data. Questions: What is the approach/steps used by Excel to get the p-value and Significant F value for the converted linear data as shown in the statistic output in the image above? It is not clear in their help page or website. Can the p-value and Significant F could be mathematically calculated for exponential regression without using a statistical tool? Can you assist to point me to the right link if this has been answered before.
