  • Return popupmenu selection in MATLAB using one line of code

    - by Doresoom
    I have a GUI which uses a selection from a popupmenu in another callback. Is there a way to return the selected value of the popupmenu in only one line without creating any temporary variables? I've tried several solutions, but I've only managed two lines with one temporary variable: Three lines: list=get(handles.popupmenu1,'String'); val=get(handles.popupmenu1,'Value'); str=list{val}; Two lines: temp=get(handles.popupmenu1,{'String','Value'}); str=temp{1}{temp{2}}; Can anyone shave it down to one? PS, It's a dynamic menu, so I can't just use get(handles.popupmenu1,'Value') and ignore the string component altogether.)

  • IQueryable Where fails to work

    - by Steve
    I am using N-Hibernate and have a class/table called Boxers I also have a prospect table which tells use if the boxer is a prospect. (this table is one column of just the boxersID) So i Want to get all boxers that are prospects (meaning all boxers that have there id in the prospects table) Public static IQueryable<Boxer> IsProspect(this IQueryable<Boxer> query) { return query.Where(x => x.Prospect != null); } this doesnt trim down my list of boxers to the boxers that are prospect... yet if i debug and look at any boxer it will have True or false next to each one correctly... Why isnt the where clause correctly trimming down the list?

  • SQL to get range of results in alphabetical order

    - by Tom Gullen
    I have a table, tblTags which works in much the same way as StackOverflows tagging system. When I view a tags page, let's say the tag Tutorial I want to display the 10 tags before and after it in alphabetical order. So if we are given the tag Tutorial of ID 30 how can we return a record set in the order resembling: Tap Tart > Tutorial Umbrellas Unicorns Xylaphones I have thought of ways of doing this, badly, in my opinion as they involve retrieving ugly amounts of data. I'm not sure if it's possible to do something along the lines of (pseudo): SELECT RANGE(0 - 30) FROM tblTags ORDER BY Name ASC But how do you know the position of the tutorial tag in the list in an efficient manner without traversing the entire list until you find it? I'm using SQL Server 2008 R2 Express with LINQ if it makes any difference, SQL queries or LINQ would be great answers, thanks!

  • C# Lists, Foreach, and Types

    - by user406470
    I was wondering if there is a version of foreach that checks only for a specific type and returns it. For example consider this class tree: org.clixel.ClxBasic - org.clixel.ClxObject - org.clixel.ClxSprite - WindowsGame1.test Then consider this code public List<ClxBasic> objects = new List<ClxBasic>(); foreach(GroupTester tester in objects) { tester.GroupTesterOnlyProperty = true; } tester.GroupTesterOnlyProperty is a property created in GroupTester. Is there some way to make something like this work, like an overload of foreach, or another snippet that might help me? I want to make it easy for a programmer to sort through the lists grabbing only what type they need.

  • What would be the best schema to store the 'address' for different entities?

    - by Cesar
    Suppose we're making a system where we have to store the addrees for buildings, persons, cars, etc. The address 'format' should be something like: State (From a State list) County (From a County List) Street (free text, like '5th Avenue') Number (free text, like 'Chrysler Building, Floor 10, Office No. 10') (Yes I don't live in U.S.A) What would be the best way to store that info: Should I have a Person_Address, Car_Address, ... Or the address info should be in columns on each entity, Could we have just one address table and try to link each row to a different entity? Or are there another 'better' way to handle this type of scenario? How would yo do it?

  • How can I merge CSS definitions in files into inline style attributes, using Perl?

    - by mintywalker
    Many email clients don't like linked CSS stylesheets, or even the embedded <style> tag, but rather want the CSS to appear inline as style attributes on all your markup. BAD: <link rel=stylesheet type="text/css" href="/style.css"> BAD: <style type="text/css">...</style> WORKS: <h1 style="margin: 0">...</h1> However this inline style attribute approach is a right pain to manage. I've found tools for Ruby and PHP that will take a CSS file and some separate markup as input and return you the merged result - a single file of markup with all the CSS converted to style attributes. I'm looking for a Perl solution to this problem, but I've not found one on CPAN or by searching Google. Any pointers? Alternatively, are there CPAN modules one could combine to achieve the same result? Ruby http://code.dunae.ca/premailer.web/ PHP http://www.pelagodesign.com/sidecar/emogrifier/ Perl ?

  • emacs: how do I use edebug on code that is defined in a macro?

    - by Cheeso
    I don't even know the proper terminology for this lisp syntax, so I don't know if the words I'm using to ask the question, make sense. But the question makes sense, I'm sure. So let me just show you. cc-mode (cc-fonts.el) has things called "matchers" which are bits of code that run to decide how to fontify a region of code. That sounds simple enough, but the matcher code is in a form I don't completely understand, with babckticks and comma-atsign and just comma and so on, and furthermore it is embedded in a c-lang-defcost, which itself is a macro. And I want to run edebug on that code. Look: (c-lang-defconst c-basic-matchers-after "Font lock matchers for various things that should be fontified after generic casts and declarations are fontified. Used on level 2 and higher." t `(;; Fontify the identifiers inside enum lists. (The enum type ;; name is handled by `c-simple-decl-matchers' or ;; `c-complex-decl-matchers' below. ,@(when (c-lang-const c-brace-id-list-kwds) `((,(c-make-font-lock-search-function (concat "\\<\\(" (c-make-keywords-re nil (c-lang-const c-brace-id-list-kwds)) "\\)\\>" ;; Disallow various common punctuation chars that can't come ;; before the '{' of the enum list, to avoid searching too far. "[^\]\[{}();,/#=]*" "{") '((c-font-lock-declarators limit t nil) (save-match-data (goto-char (match-end 0)) (c-put-char-property (1- (point)) 'c-type 'c-decl-id-start) (c-forward-syntactic-ws)) (goto-char (match-end 0))))))) I am reading up on lisp syntax to figure out what those things are and what to call them, but aside from that, how can I run edebug on the code that follows the comment that reads ;; Fontify the identifiers inside enum lists. ? I know how to run edebug on a defun - just invoke edebug-defun within the function's definition, and off I go. Is there a corresponding thing I need to do to edebug the cc-mode matcher code forms?

  • How to set utf8 in the auto-generated PHP code of flash builder 4 ?

    - by Mark
    HI, PHP problem here (I think): I've just created a Flex (Flash Builder) project with a datagrid linked to a database - the database is all utf8. When I run the project using the auto-generated code in flex4, the non-English part comes like ????? while the English part comes fine. The auto-generated PHP code uses mysqli. I've tried: $this->connection->set_charset('utf8'); or mysqli_query($this->connection,"SET NAMES utf8"); I also tried writing the code myself (I'm not a PHP guy): mysql_query("set names utf8"); was fine - but that's mysql and not mysqli (that's an "i" after the mysql) and I want to use the auto-generated code... any help is appreciated.

  • JQuery UI Tabs + Wordpress issues

    - by Sahat
    Hello dear Stackoverflow gurus, I am trying to integrate JQuery tabs with my WordPress blog, to replace old HTML Navigation menu. I am half way there but not quiet... Take a look for yourself: http://www.isahat.com The template breaks right away since the first button of the Tab menu is linked to index.php like so: Home Info The second tab menu shows my Info page just fine, but on top of everything else. My home page and everything else gets shifted down to make room for Info page. And why after clicking on any article or even the tab link, my tab menu disappears and all my navigation links turn into a bullet list? Thank you, Sahat.

  • Drag N Drop utilizing simple cursor

    - by Cameron
    I'm using CommonsGuy's drag n drop example and I am basically trying to integrate it with the Android notepad example. Drag N Drop Out of the 2 different drag n drop examples i've seen they have all used a static string array where as i'm getting a list from a database and using simple cursor adapter. So my question is how to get the results from simple cursor adapter into a string array, but still have it return the row id when the list item is clicked so I can pass it to the new activity that edits the note. Here is my code: Cursor notesCursor = mDbHelper.fetchAllNotes(); startManagingCursor(notesCursor); // Create an array to specify the fields we want to display in the list (only NAME) String[] from = new String[]{WeightsDatabase.KEY_NAME}; // and an array of the fields we want to bind those fields to (in this case just text1) int[] to = new int[]{R.id.weightrows}; // Now create a simple cursor adapter and set it to display SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.weights_row, notesCursor, from, to); setListAdapter(notes); And here is the code i'm trying to work that into. public class TouchListViewDemo extends ListActivity { private static String[] items={"lorem", "ipsum", "dolor", "sit", "amet", "consectetuer", "adipiscing", "elit", "morbi", "vel", "ligula", "vitae", "arcu", "aliquet", "mollis", "etiam", "vel", "erat", "placerat", "ante", "porttitor", "sodales", "pellentesque", "augue", "purus"}; private IconicAdapter adapter=null; private ArrayList<String> array=new ArrayList<String>(Arrays.asList(items)); @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); setContentView(R.layout.main); adapter=new IconicAdapter(); setListAdapter(adapter); TouchListView tlv=(TouchListView)getListView(); tlv.setDropListener(onDrop); tlv.setRemoveListener(onRemove); } private TouchListView.DropListener onDrop=new TouchListView.DropListener() { @Override public void drop(int from, int to) { String item=adapter.getItem(from); adapter.remove(item); adapter.insert(item, to); } }; private TouchListView.RemoveListener onRemove=new TouchListView.RemoveListener() { @Override public void remove(int which) { adapter.remove(adapter.getItem(which)); } }; class IconicAdapter extends ArrayAdapter<String> { IconicAdapter() { super(TouchListViewDemo.this, R.layout.row2, array); } public View getView(int position, View convertView, ViewGroup parent) { View row=convertView; if (row==null) { LayoutInflater inflater=getLayoutInflater(); row=inflater.inflate(R.layout.row2, parent, false); } TextView label=(TextView)row.findViewById(R.id.label); label.setText(array.get(position)); return(row); } } } I know i'm asking for a lot, but a point in the right direction would help quite a bit! Thanks

  • Using reshape + cast to aggregate over multiple columns

    - by DamonJW
    In R, I have a data frame with columns for Seat (factor), Party (factor) and Votes (numeric). I want to create a summary data frame with columns for Seat, Winning party, and Vote share. For example, from the data frame df <- data.frame(party=rep(c('Lab','C','LD'),times=4), votes=c(1,12,2,11,3,10,4,9,5,8,6,15), seat=rep(c('A','B','C','D'),each=3)) I want to get the output seat winner voteshare 1 A C 0.8000000 2 B Lab 0.4583333 3 C C 0.5000000 4 D LD 0.5172414 I can figure out how to achieve this. But I'm sure there must be a better way, probably a cunning one-liner using Hadley Wickham's reshape package. Any suggestions? For what it's worth, my solution uses a function from my package djwutils_2.10.zip and is invoked as follows. But there are all sorts of special cases it doesn't deal with, so I'd rather rely on someone else's code. aggregateList(df, by=list(seat=seat), FUN=list(winner=function(x) x$party[which.max(x$votes)], voteshare=function(x) max(x$votes)/sum(x$votes)))

  • In which controller do you put the CRUD for the child part of a relationship?

    - by uriDium
    I am using ASP.Net MVC but this probably applies to all MVC patterns in general. My problem, for example I have companies and in each company I have a list of contacts. When I have selected a company I can see its details and a list of the contacts for that company. When I want to add a new contact for that company, should the implementation of that action go into the company controller as an "AddContact" action or should it go into the contact controller into a "New" action and we pass the Company ID in the URL? What is the usual way of dealing with this sort of thing in ASP.Net MVC? Is there a better stategy?

  • Somewhat newb question about assy and the heap.

    - by Eric M
    Ultimately I am just trying to figure out how to dynamically allocate heap memory from within assembly. If I call Linux sbrk() from assembly code, can I use the address returned as I would use an address of a statically (ie in the .data section of my program listing) declared chunk of memory? I know Linux uses the hardware MMU if present, so I am not sure if what sbrk returns is a 'raw' pointer to real RAM, or is it a cooked pointer to RAM that may be modified by Linux's VM system? I read this: How are sbrk/brk implemented in Linux?. I suspect I can not use the return value from sbrk() without worry: the MMU fault on access-non-allocated-address must cause the VM to alter the real location in RAM being addressed. Thus assy, not linked against libc or what-have-you, would not know the address has changed. Does this make sense, or am I out to lunch?

  • Please suggest me the best way to design my database.

    - by Raymond Ho
    I have a table named "Pages" and a table named "Categories". Each entry of the table "Pages" is linked to the table "Categories". The "Categories" table have 5 entries, they are: "Car", "Websites", "Technology", "Mobile Phones", and "Interest". So each time I put an entry to the "Pages" table, I need to map it to the "Categories" table so are arranged properly. Here's my table: Pages ______ id [PK] name url Categories ______ id [PK] Categoryname Pages2Categories ______ Pages.id Categories.id So my question is, is this the most efficient way to create this kind of relationships between tables? It seems very amateur

  • How to do query auto-completion/suggestions in Lucene?

    - by Mat Mannion
    I'm looking for a way to do query auto-completion/suggestions in Lucene. I've Googled around a bit and played around a bit, but all of the examples I've seen seem to be setting up filters in Solr. We don't use Solr and aren't planning to move to using Solr in the near future, and Solr is obviously just wrapping around Lucene anyway, so I imagine there must be a way to do it! I've looked into using EdgeNGramFilter, and I realise that I'd have to run the filter on the index fields and get the tokens out and then compare them against the inputted Query... I'm just struggling to make the connection between the two into a bit of code, so help is much appreciated! To be clear on what I'm looking for (I realised I wasn't being overly clear, sorry) - I'm looking for a solution where when searching for a term, it'd return a list of suggested queries. When typing 'inter' into the search field, it'll come back with a list of suggested queries, such as 'internet', 'international', etc.

  • Security for web services only used from a Silverlight application?

    - by Lasse V. Karlsen
    I have googled a bit for how I should handle security in a web service application when the application is basically the data repository for a Silverlight application, but have gotten inconclusive results. The Silverlight application is not supposed to have its own user authentication, since it will be reachable only through a web application that the user have already authenticated to get into. As such, I was thinking I could simply add a parameter to the SL application that is a cookie-type value, with a certain lifetime, linked to the user in the database. The SL application would then have to pass this value alongside other parameters to the web services. Since the web service is hopefully going to be a generic web service endpoint, few methods, adding an extra parameter at this level will not be a problem. But, am I supposed to roll this system on my own? It sounds to me as this isn't exactly new features that nobody has considered before, so what are my options?

  • Why is this statement treated as a string instead of its result?

    - by reve_etrange
    I am trying to perform some composition-based filtering on a large collection of strings (protein sequences). I wrote a group of three subroutines in order to take care of it, but I'm running into trouble in two ways - one minor, one major. The minor trouble is that when I use List::MoreUtils 'pairwise' I get warnings about using $a and $b only once and them being uninitialized. But I believe I'm calling this method properly (based on CPAN's entry for it and some examples from the web). The major trouble is an error "Can't use string ("17/32") as HASH ref while "strict refs" in use..." It seems like this can only happen if the foreach loop in &comp is giving the hash values as a string instead of evaluating the division operation. I'm sure I've made a rookie mistake, but can't find the answer on the web. The first time I even looked at perl code was last Wednesday... use List::Util; use List::MoreUtils; my @alphabet = ( 'A', 'R', 'N', 'D', 'C', 'Q', 'E', 'G', 'H', 'I', 'L', 'K', 'M', 'F', 'P', 'S', 'T', 'W', 'Y', 'V' ); my $gapchr = '-'; # Takes a sequence and returns letter = occurrence count pairs as hash. sub getcounts { my %counts = (); foreach my $chr (@alphabet) { $counts{$chr} = ( $[0] =~ tr/$chr/$chr/ ); } $counts{'gap'} = ( $[0] =~ tr/$gapchr/$gapchr/ ); return %counts; } # Takes a sequence and returns letter = fractional composition pairs as a hash. sub comp { my %comp = getcounts( $[0] ); foreach my $chr (@alphabet) { $comp{$chr} = $comp{$chr} / ( length( $[0] ) - $comp{'gap'} ); } return %comp; } # Takes two sequences and returns a measure of the composition difference between them, as a scalar. # Originally all on one line but it was unreadable. sub dcomp { my @dcomp = pairwise { $a - $b } @{ values( %{ comp( $[0] ) } ) }, @{ values( %{ comp( $[1] ) } ) }; @dcomp = apply { $_ ** 2 } @dcomp; my $dcomp = sqrt( sum( 0, @dcomp ) ) / 20; return $dcomp; } Much appreciation for any answers or advice!

  • C# Design a class with interface?

    - by Haroon
    I am having a bit of trouble understanding how I will design a class. My class will have 3 methods ICollection<Field> GetFields(); //perform validation internally - return back the object T UpdateFields(ICollection<Field> fields); //pass in model object with values on it, set up fields, then pass back all fields ICollection<Field> GetFieldsWithValues(T object); What is the best way to construct/design such a class keeping in mind: 1. The model object I pass in will be one of 3 or 4 tables, however when I call GetFIelds - internally for each object I know what fields will be there i.e. list.add(new Field{name = "id", value = "5"}); list.add(new Field{name = "nameofcompany", value = "super guys"});

  • Jquery: How can I Get/Set html of a String Variable by using Jquery Selectors ?

    - by ryan.dingy
    Hi all. Firstly, sorry for my English (I'm from China). By reading this article(http://stackoverflow.com/questions/2421719/how-to-apply-jquery-element-selection-to-a-string-variable), I can successfully get Elements from a String which stores HTML text. For example: var htmlstr = "<div><ul><li>some text 1</li></ul></div><div><ul id=list><li>some text 2</li></ul></div>"; var s = $('ul#list', $(htmlstr)).html(); s will be <li>some text 2</li>. It's what I want. But the question is, if I want to add another LI element to this string (htmlstr) how can I do? I set s = new html string but htmlstr doesn't change. Thanks

  • Optimizing simple search script in PowerShell

    - by cc0
    I need to create a script to search through just below a million files of text, code, etc. to find matches and then output all hits on a particular string pattern to a CSV file. So far I made this; $location = 'C:\Work*' $arr = "foo", "bar" #Where "foo" and "bar" are string patterns I want to search for (separately) for($i=0;$i -lt $arr.length; $i++) { Get-ChildItem $location -recurse | select-string -pattern $($arr[$i]) | select-object Path | Export-Csv "C:\Work\Results\$($arr[$i]).txt" } This returns to me a CSV file named "foo.txt" with a list of all files with the word "foo" in it, and a file named "bar.txt" with a list of all files containing the word "bar". Is there any way anyone can think of to optimize this script to make it work faster? Or ideas on how to make an entirely different, but equivalent script that just works faster? All input appreciated!
