  • Generating pagination links

    - by alpheus
    I am trying to implement a paging system that displays nearby page numbers as well as pages at each extreme. For example, if the user is on page 20 of 40, the following links should be displayed: 1, 2 ... 18, 19, [20], 21, 22 ... 39, 40. The solution would be similar to the one described here: http://90poe.com/alex-lee-on-bell-curve-pagination I have seen code to do this in PHP, but not in ASP.net (ideally I am looking for C# code). If anyone has done anything like this previously, it would be very helpful to see your code.

  • Remove duplicates in entries, scala way

    - by andersbohn
    I have a list of entries stating a production value in a given interval. Entries stating the exact same value at a later time adds no information and can safely be left out. case class Entry(minute:Int, production:Double) val entries = List(Entry(0, 100.0), Entry(5, 100.0), Entry(10, 100.0), Entry(20, 120.0), Entry(30, 100.0), Entry(180, 0.0)) Experimenting with the scala 2.8 collection functions, so far I have this working implementation: entries.foldRight(List[Entry]()) { (entry, list) => list match { case head :: tail if (entry.production == head.production) => entry :: tail case head :: tail => entry :: list case List() => entry :: List() } } res0: List[Entry] = List(Entry(0,100.0), Entry(20,120.0), Entry(30,100.0), Entry(180,0.0)) Any comments? Am I missing out on some scala magic?

  • How to trigger an event in input text after I stop typing/writting?

    - by user1386320
    I want to trigger event just right after I stop typing (not while typing) characters in my input textbox. I've tried with: $('input#username').keypress(function() { var _this = $(this); // copy of this object for further usage setTimeout(function() { $.post('/ajax/fetch', { type: 'username', value: _this.val() }, function(data) { if(!data.success) { // continue working } else { // throw an error } }, 'json'); }, 3000); }); But this example produces a timeout for every typed character and I get about 20 AJAX requests if I type-in 20 characters. On this fiddle I demonstrate the same problem with a simple alert instead of an AJAX. Is there a solution for this or I'm just using a bad approach for this?

  • Doctrine: Mixing YAML markup and db manager (navicat) editing?

    - by ropstah
    I think the answer to this question should be: No. However I hope to be corrected. I'd like to edit our database using a mixture of YAML markup + Doctrine createTables() and Navicat editing. Can I maintain the inheritance which is marked up? Example (4 steps, at step 4, Doctrine is in no way able to re-create the inheritance schema... or is it?): Step 1: Create YAML with inheritance --- Entity: columns: username: string(20) password: string(16) created_at: timestamp updated_at: timestamp User: inheritance: extends: Entity type: column_aggregation keyField: type keyValue: 1 Group: inheritance: extends: Entity type: column_aggregation keyField: type keyValue: 2 Step 2: Create tables using Doctrine (and drop/create db if nessecary) Created sql: CREATE TABLE entity (id BIGINT AUTO_INCREMENT, username VARCHAR(20), password VARCHAR(16), created_at DATETIME, updated_at DATETIME, type VARCHAR(255), PRIMARY KEY(id)) ENGINE = INNODB Step 3: Edit table using Navicat Step 4: Refresh YAML file because of 'external' edits...

  • How can I initialize a 2d array in Perl?

    - by Mark
    How do I initialize a 2d array in perl? I am trying the following code: 0 use strict; 10 my @frame_events = (((1) x 10), ((1) x 10)); 20 print "$frame_events[1][1]\n"; but it gives the following error: Can't use string ("1") as an ARRAY ref while "strict refs" in use at ./dyn_pf.pl line 20. This syntax only seems to initialize a 1d array as print "$frame_events[1]\n" works. Though perl doesn't give any error during the assignment.

  • TypoScript: {field:uid} replacement not working | Different CSS class per menu item

    - by Alex
    I have a header menu and try to define different CSS classes for each item. This is what I have: 20 = HMENU 20 { special = directory special.value = 107 1 = TMENU 1 { wrap = <ul class="foo" id="mymenu">|</ul> expAll = 1 NO = 1 NO.allWrap = <li class="first menu_{field:uid}">|</li> || <li class="menu_{field:uid}">|</li> || <li class="last menu_{field:uid}">|</li> } } But in the HTML output I simply get class="first menu_{field:uid}" and nothing is replaced.

  • Recursive algorithm for coalescing / collapsing list of dates into ranges.

    - by Dycey
    Given a list of dates 12/07/2010 13/07/2010 14/07/2010 15/07/2010 12/08/2010 13/08/2010 14/08/2010 15/08/2010 19/08/2010 20/08/2010 21/08/2010 I'm looking for pointers towards a recursive pseudocode algorithm (which I can translate into a FileMaker custom function) for producing a list of ranges, i.e. 12/07/2010 to 15/07/2010, 12/08/2010 to 15/08/2010, 19/08/2010 to 20/08/2010 The list is presorted and de-deuplicated. I've tried starting from both the first value and working forwards, and the last value and working backwards but I just can't seem to get it to work. Having one of those frustrating days... It would be nice if the signature was something like CollapseDateList( dateList, separator, ellipsis ) :-)

  • How to build a LINQ query from text at runtime?

    - by Danvil
    I have a class A { public int X; public double Y; public string Z; // and more fields/properties ... }; and a List<A> data and can build a linq query like e.g. var q = from a in data where a.X > 20 select new {a.Y, a.Z}; Then dataGridView1.DataSource = q.ToList(); displays the selection in my DataGridView. Now the question, is it possible to build the query from a text the user has entered at runtime? Like var q = QueryFromText("from a in data where a.X > 20 select new {a.Y, a.Z}"); The point being, that the user (having programming skills) can dynamically and freely select the displayed data.

  • Rails: Thread won't affect database unless joined to main Thread

    - by hatboysam
    I have a background operation I would like to occur every 20 seconds in Rails given that some condition is true. It kicked off when a certain controller route is hit, and it looks like this def startProcess argId = self.id t = Thread.new do while (Argument.isRunning(argId)) do Argument.update(argId) Argument.markVotes(argId) puts "Thread ran" sleep 20 end end end However, this code does absolutely nothing to my database unless I call "t.join" in which case my whole server is blocked for a long time (but it works). Why can't the read commit ActiveRecords without being joined to the main thread? The thread calls methods that look something like def sample model = Model.new() model.save() end but the models are not saved to the DB unless the thread is joined to the main thread. Why is this? I have been banging my head about this for hours.

  • In R draw two lines, with slopes double and half the value of the best fit line

    - by D W
    I have data with a best fit line draw. I need to draw two other lines. One needs to have double the slope and the other need to have half the slope. Later I will use the region to differentially color points outside it as per: http://stackoverflow.com/questions/2687212/conditionally-colour-data-points-outside-of-confidence-bands-in-r Example dataset: ## Dataset from http://www.apsnet.org/education/advancedplantpath/topics/RModules/doc1/04_Linear_regression.html ## Disease severity as a function of temperature # Response variable, disease severity diseasesev<-c(1.9,3.1,3.3,4.8,5.3,6.1,6.4,7.6,9.8,12.4) # Predictor variable, (Centigrade) temperature<-c(2,1,5,5,20,20,23,10,30,25) ## For convenience, the data may be formatted into a dataframe severity <- as.data.frame(cbind(diseasesev,temperature)) ## Fit a linear model for the data and summarize the output from function lm() severity.lm <- lm(diseasesev~temperature,data=severity) # Take a look at the data plot( diseasesev~temperature, data=severity, xlab="Temperature", ylab="% Disease Severity", pch=16, pty="s", xlim=c(0,30), ylim=c(0,30) ) title(main="Graph of % Disease Severity vs Temperature") par(new=TRUE) # don't start a new plot abline(severity.lm, col="blue")

  • Why I am forced to write the (Data Constructor) name with first letter in small case?

    - by Optimight
    Why I am forced to write "liOfLi" in place of "LiOfLi"? Please guide. code in baby.hs LiOfLi = [ [1,3,4,5,6,8], [ 12, 13, 15, 16, 19, 20], [23, 24, 25, 45, 56] ] ghci response: ghci :l baby [1 of 1] Compiling Main ( baby.hs, interpreted ) Failed, modules loaded: none. ghci baby.hs:29:1: Not in scope: data constructor `LiOfLi' When changing the initial letter to smaller case code in baby.hs liOfLi = [ [1,3,4,5,6,8], [ 12, 13, 15, 16, 19, 20], [23, 24, 25, 45, 56] ] ghci response: ghci :l baby [1 of 1] Compiling Main ( baby.hs, interpreted ) Ok, modules loaded: Main. Following are the SO questions I refered but I failed to understand the rules/ logic and get the answer for (my) abovementioned question. Why does Haskell force data constructor's first letter to be upper case? the variable names need to be lowercase.

  • Codeigniter - selecting children and parents from db

    - by Tomek Buszewski
    I want to pull from my database records corresponding to parent_id, like this: function getChildren($id, $parent_id) { $q = $this->db->select('id, name, slug, plat'); $q = $this->db->from('games'); $q = $this->db->where('parent_id',$id); $q = $this->db->or_where('id',$parent_id); $q = $this->db->get(); return $q->result_array(); } It - if it's a children game - get parent_id and search for a game with such id and for other games that has parent_id same as this one. If it's the parent game, it only looks for games with parent_id same as it's id. The problem is... it's not always working. I have four games in db: id | parent_id | title 15 | 0 | Abe 19 | 15 | Abe 20 | 0 | RE2 21 | 20 | RE2 DS First two works, last two - only children (id = 21) shows parent.

  • undesirable cropping of Label that has been rotated 90 degrees

    - by 108980470541437452574
    Hello, I am creating 2 columns. left column will show caption of the DataGrid which will be in right column. <Grid.ColumnDefinitions> <ColumnDefinition Width="20" /> <ColumnDefinition /> </Grid.ColumnDefinitions> <Label Grid.Column="0" Name="FilterLabel"> <Label.RenderTransform> <TransformGroup> <RotateTransform Angle="-90" /> </TransformGroup> </Label.RenderTransform> </Label> the problem here is that the lable gets rendered horizontally first, and cropped at 20 pixels. So after it has been rotated, only first few letters appear rendered in left column. as soon as i make the left column wider, more letters get rendered.

  • R software : How to extract values from rasterstack with xy coordinates?

  • Split a string and join it back together in a different order?

    - by Xaisoft
    What is the most concise, yet readable way to split a string and put join it back together in a different order. For example, I want to split the following string: 10-20-30-4000-50000 and I would do this via: string[] tokens = original.Split('-'); and now I want to put it back together in this order: 30-20-10-4000-50000 I know I can use Join to put it back together in it's original form, but I don't want that. The only thing I can think of right now is: string modified = string.Format("{0}{1}{2}{3}{4}",tokens[2],tokens[1],tokens[0],tokens[3], tokens[4]); I realized that if I do: string modified = string.Format("{2}{1}{0}{3}{4}", tokens); it does not keep the dashes which is what I want so is to do that, should I just do: string modified = string.Format("{2}-{1}-{0}-{3}-{4}", tokens);

  • SQL Server, fetching data from multiple joined tables. Why is slow?

    - by user562192
    I have problem with performance when retrieving data from SQL Server. My sql query looks something like this: SELECT table_1.id, table_1.value, table_2.id, table_2.value,..., table_20.id, table_20.value From table_1 INNER JOIN table_2 ON table_1.id = table_2.table_1_id INNER JOIN table_3 ON table_2.id = table_3.table_2_id... WHERE table_1.row_number BETWEEN 1 AND 20 So, I am fetching 20 results. This query takes about 5 seconds to execute. When I select only table_1.id, it returns results instantly. Because of that, I guess that problem is not in JOINs, it is in retrieving data from multiple tables. Any suggestions how I would speed up this query?

  • Why does the assignment operator return a value and not a reference?

    - by Nick Lowman
    I saw the example below explained on this site and thought both answers would be 20 and not the 10 that is returned. He wrote that both the comma and assignment returns a value, not a reference. I don't quite understand what that means. I understand it in relation to passing variables into functions or methods i.e primitive types are passed in by value and objects by reference but I'm not sure how it applies in this case. I also understand about context and the value of 'this' (after help from stackoverflow) but I thought in both cases I would still be invoking it as a method, foo.bar() which would mean foo is the context but it seems both result in a function call bar(). Why is that and what does it all mean? var x = 10; var foo = { x: 20, bar: function () {return this.x;} }; (foo.bar = foo.bar)();//returns 10 (foo.bar, foo.bar)();//returns 10
