  • Accessing the params hash for year and month rails and using in helper

    - by Matt
    So I took some php code and turned it into a calendar with a helper to make a simple calendar. I got my data from inside the helper: def calendar_maker a = Time.now b = a.month d = a.year h = Time.gm(d,b,1) #first day of month Now I want to try and do it with parameters within my method #from the helper file def calendar_maker(year, month) a = Time.now b = month c = year h = Time.gm(d,b,1) #first day of month #from my html.erb file <%= @month %> and <%= @year %> <%= params["month"] %><br /> <%= params["action"] %><br /> <%= params["year"] %><br /> <%= calendar_maker( @year, @month) %> #from controller file def calendar @month = params[:month] @year = params[:year] end Anyways mistakes were made and not finding documentation anywhere or not looking in the right place. How do I get this to work with my params hash. Thanks for the help.

  • Using CreateFileMapping between two programs - C

    - by Jamie Keeling
    Hello, I have two window form applications written in C, one holds a struct consisting of two integers, another will receive it using the CreateFileMapping. Although not directly related I want to have three events in place so each of the processes can "speak" to each other, one saying that the first program has something to pass to the second, one saying the first one has closed and another saying the second one has closed. What would be the best way about doing this exactly? I've looked at the MSDN entry for the CreateFileMapping operation but I'm still not sure as to how it should be done. I didn't want to start implementing it without having some sort of clear idea as to what I need to do. Thanks for your time.

  • the problem about different treatment to __VA_ARGS__ when using VS 2008 and GCC

    - by liuliu
    I am trying to identify a problem because of an unusual usage of variadic macros. Here is the hypothetic macro: #define va(c, d, ...) c(d, __VA_ARGS__) #define var(a, b, ...) va(__VA_ARGS__, a, b) var(2, 3, printf, “%d %d %d\n”, 1); For gcc, the preprocessor will output printf("%d %d %d\n", 1, 2, 3) but for VS 2008, the output is printf, “%d %d %d\n”, 1(2, 3); I suspect the difference is caused by the different treatment to VA_ARGS, for gcc, it will first expand the expression to va(printf, "%d %d %d\n", 1, 2, 3), and treat 1, 2, 3 as the VA_ARGS for macro va. But for VS 2008, it will first treat b as VA_ARGS for macro va, and then do the expansion. Which one is correct interpretation for C99 variadic macro? or my usage falls into an undefined behavior?

  • Multiple Input From Keyboard C# WPF

    - by Alex
    I am writing a Tetris clone in WPF. If I hold down the right arrow key, the current piece shifts right. For playability, I want to allow the user to press another key (i.e. F-key) and rotate the moving piece without having to let go of the right arrow key first. Currently when I do this, the piece stops shifting. My first basic attempt at this was hooking into Window_PreviewKeyDown(object sender, KeyEventArgs e) and then sending a message to the controller layer. How do I structure my input-listening code to allow this? My current code Here

  • Can you control pinterest's "find image" results?

    - by anthony
    Rather than add Pin It buttons through our site, I would like to simply control what images show up in Pinterest's "Find Image" results if a user decides to pin one of our URLs. As of now, "Find Images" allows the user to scroll through the images it finds on the page so they can select which image to pin. The "found" images start with the first jpg in the html file, I'm assuming (could that be a bad assumption??). On our site, this forces a user to scroll through about 15 navigation and promotion images before arriving at the featured product image. Is there any way to specify this image to show first in those results? Maybe through a meta tag, or by adding a class or id to the element? Without a public Pinterest API, this seems like just guesswork, but I wanted to see if anyone else has run into this, or solved this. Thanks.

  • numberOfSectionsInTableView is requested in/after viewDidLoad ONLY if tableview is empty

    - by Ben Packard
    A simple tableviewController, empty. A modal that can be launched from a button. No data in the data source for the tableview, and no rows displayed. I open the modal, use it to add an item, and return to the tableview controller. The tableview updates itself automatically, and the new row is displayed. I add a second item. The table view does NOT update automatically. I can tell by logging inside numberOfSectionsInTableView that even if I go to add the first item and cancel, the tableview refreshes - it asks for the number of sections, rows, and the cell to display (if there is one). But not if there is one pre-existing row in the table. I've scoured my code but can't find anything that would cause the tableview to know when the first item is added, but none afterwards. Any ideas? EDIT - I have further narrowed my issue so will close this shortly and post a more specific question

  • How to skip extra lines before the header of a tab delimited delimited file in R

    - by Michael Dunn
    The software I am using produces log files with a variable number of lines of summary information followed by lots of tab delimited data. I am trying to write a function that will read the data from these log files into a data frame ignoring the summary information. The summary information never contains a tab, so the following function works: read.parameters <- function(file.name, ...){ lines <- scan("tmp.log", what="character", sep="\n") first.line <- min(grep("\\t", lines)) return(read.delim(file.name, skip=first.line-1, ...)) } However, these logfiles are quite big, and so reading the file twice is very slow. Surely there is a better way?

  • ActionScript 2.0 problem with the object's _visible parameter

    - by GMan
    Hey guys, I've been trying to build something simple in Flash 8, and I stumbled across something weird I cannot explain: I have an object, and at some point of the program, I want it to be visible (it is invisible at first), so I write: _root.myObj._visible = true; _root.gameOver.swapDepths(_root.getNextHighestDepth()); //so it will be on the top and this works fine, the object becomes visible and etc. What I planned to happen next is that the user presses a button on that same object, and the object will go invisible: on(release) { trace(_root.myObj._visible); _root.myObj._visible = false; trace(_root.myObj._visible); _root.gotoAndPlay("three"); } The trace returns at first true and later on false, so the command works, but oddly the object stays visible, that's what I don't understand. Thanks everybody in advance.

  • How to make a NON-LINE based diff between two strings in Java

    - by Mycol
    I have to compare the text content of two xml elements, eg. <p>During lunch he hears strangers whispering, catching the name "Potter" and "Harry", and someone saying You-Know-Who has gone at last. </p> and <p>During dinner he hears strangers whispering, catching the name "Rossi" and "Mario", and someone saying You-Know-Who has gone at first. </p> What I'm looking for is some java libraries to make a diff between the content of paragraphs. All the tools I found makes a line diff. But they're not what I want, simply because i have no lines, but "strings" to compare. What I need is to have a char-based diff: eg. a diff that tells me something like " from the first file, remove char from 8 to 12, add the string "dinner" from char 8."

  • Display/Hide part of a list

    - by superexsl
    Hi I have an (unordered)list (generated by a repeater) of items. However, I'd like to show the first three items, and have the rest hidden by the main content div. When a button is pressed, I would like the list's div to expand, pushing the main content div down and showing the rest of the list. I was thinking of using slideDown(), but that closes the entire div ( and I would like to show the first 3 items of the list). What would be the best way to achieve an effect like this? Is there a plugin that can easily show X items of a list and the display the rest upon request? Thanks

  • Getting rid of a dangling changeset after rebase in mercurial

    - by steglig
    Hi, I did a hg update --force <repo> to get another seemingly unrelated repository into the current one. Afterwards I merged the first changeset of the other repo (to get renamings "right"). A rebase of the other repository starting from the second changeset left the first changeset (here: revision 5431) dangling in the repository: o changeset: 5433:68c67c7e0bbb | o changeset: 5432:331ee440893a |\ | | | o changeset: 5431:1023b4c44f18 | o changeset: 5430:15aff858ec36 To clean things up I'd like to get rid of revision 5431. How would I do that? Thanks.

  • Specify only the second parameter in a javascript function

    - by Ben McCormack
    The spec for the jQuery ajax.error function is: error(XMLHttpRequest, textStatus, errorThrown)Function I'm trying to catch the error and display the textStatus, but I can't figure out how to specify only the textStatus without having to put in a variable name for XMLHttpRequest and errorThrown. My code currently looks like this: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: hbAddressValidation.webServiceUrl, data: this.jsonRequest, dataType: "json", timeout: 5, success: function (msgd) { //... }, error: function (a,textStatus,b) { $("#txtAjaxError").val("There was an error in the AJAX call: " + textStatus); } }); You can see in my code that I'm putting variables a and b as placeholders for the first and last variables in the error function. I know that in my success function, I'm only providing one parameter and it works fine, but in that case data is the first parameter. In the case of error, textStatus is the second parameter, but that's the only one I want to specify. Is this possible?

  • What are the major differences between Windows CE and Windows Mobile for a programmer?

    - by Brad Bruce
    What are the major differences between Windows CE and Windows Mobile for a programmer? I'd love to find a feature table, but haven't been able to find one on the Microsoft web site. I'm starting to work on a project involving industrial handheld terminals. I'm early into the design phase and need to find a comparison of Windows CE and Windows Mobile. Many of the people I'll be talking to jump on the first option that sounds "good enough". I want my first suggestion to be the best based on their needs. We're talking heavy duty hardware with a heavy duty price. I've got to get the programming questions out of the way early. We're currently a MFC6 and .Net 2.0 shop

  • generate an array from an array with conditions

    - by Aman
    Suppose i have an array $x = (31,12,13,25,18,10); I want to reduce this array in such a way that the value of each array element is 32. so after work my array will become $newx = (32,32,32,13); I have to generate this array in such a way the sum of array values is never greater than 32. so to create first value, i will reduce 1 from second index value i.e. 12, so the second value will become 11 and first index value will become 31+1 =32. This process should continue so that each array value becomes equal to 32.

  • Chain dynamically created dropdowns with JQuery

    - by ricardocasares
    I'm building some kind of indefinite filters for an app, and I'm havin this problem when I clone some selects. The things is this selects are chained between them, trough the Chained Selects jQuery plugin. The problem is that every time I clone the selects, the chaining stops working, and I've tryed everything, such as .live() to make it work, but it seems I'm out of luck :D Here you have a sample of what I'm talking about, http://jsfiddle.net/7K2Eu/63/ At first, the selects chain normally, but when I clone the form, they stop working, except for the first row of selects. Thank you!!

  • Ruby: Twitter API: Get All followers

    - by user28871
    Hi, Anyone have any idea why the next cursor isn't changing in the below code? cursor = "-1" followerIds = [] while cursor != 0 do followers = Twitter.follower_ids("IDTOLOOKUP",{"cursor"=>cursor}) cursor = followers.next_cursor followerIds+= followers.ids sleep(2) end After the first iteration where cursor = -1, it gets assigned the nextcursor from the twitter api. However, when this is sent to the twitter API on subsequent iterations, I get the same response back as I did the first time.. with the same next_cursor. Any ideas what I'm doing wrong? I'm using the twitter gem.

  • How to print lines from a file that have repeated more than six times

    - by Mike
    I have a file containing the data shown below. The first comma-delimited field may be repeated any number of times, and I want to print only the lines after the sixth repetition of any value of this field For example, there are eight fields with 1111111 as the first field, and I want to print only the seventh and eighth of these records Input file: 1111111,aaaaaaaa,14 1111111,bbbbbbbb,14 1111111,cccccccc,14 1111111,dddddddd,14 1111111,eeeeeeee,14 1111111,ffffffff,14 1111111,gggggggg,14 1111111,hhhhhhhh,14 2222222,aaaaaaaa,14 2222222,bbbbbbbb,14 2222222,cccccccc,14 2222222,dddddddd,14 2222222,eeeeeeee,14 2222222,ffffffff,14 2222222,gggggggg,14 3333333,aaaaaaaa,14 3333333,bbbbbbbb,14 3333333,cccccccc,14 3333333,dddddddd,14 3333333,eeeeeeee,14 3333333,ffffffff,14 3333333,gggggggg,14 3333333,hhhhhhhh,14 Output: 1111111,gggggggg,14 1111111,hhhhhhhh,14 2222222,gggggggg,14 3333333,gggggggg,14 3333333,hhhhhhhh,14 What I have tried is to transponse the 2nd and 3rd fields with respect to 1st, so that I can use nawk on the field of $7 or $8 #!/usr/bin/ksh awk -F"," '{ a[$1]; b[$1]=b[$1]","$2 c[$1]=c[$1]","$3} END{ for(i in a){ print i","b[i]","c[i]} } ' file > output.txt

  • Problem with finding the next word in RichTextBox

    - by paradisonoir
    As I enter a character in my RichTextBox, I want to get the next character from the its TextRange. So here is how I do it: TextPointer ptr1= RichTextBox.CaretPosition; char nextChar = GetNextChar(); while (char.IsWhiteSpace(nextChar)) { ptr1= ptr1.GetNextInsertionPosition(LogicalDirection.Forward); nextChar = GetCharacterAt(Ptr1); } then I get the ptr1 of the next character and from the TextPointer, I get the TextRange, and do my changes. So here is the problem? when the next word is spelled correctly, I have no problem, but if it's not spelled properly then ptr1 would not point to the first character of the next word (the second character), and if I use GetNextContextPosition(LogicalDirection.Forward) it would give me the first letter of the next word if it's misspelled. So depending on the spelling only one of them works? I was just wondering if you have any idea about this problem? Is there anything wrong I am doing here?

  • Setting tabindex in dynamic table vertically then horizontally

    - by Wil
    I have a page that is currently generating dynamically created textboxes in a table format. The users are requesting that the tab order be changed from horizontal-vertical to vertical-horizontal. I know that you can use the tabindex attribute to control the tab ordering, but I can't for the life of me figure out the right way to get the sequential number properly for the textboxes. I guess this is more of a math question than anything else! FYI, the textboxes are made while looping two different collections. First collection looped to make the rows, for each row, second collection (which is a property of the first collection objects) is looped to create the columns. Any help would be greatly appreciated. Thanks!

  • Singleton constructor question

    - by gillyb
    Hi, I created a Singleton class in c#, with a public property that I want to initialize when the Singleton is first called. This is the code I wrote : public class BL { private ISessionFactory _sessionFactory; public ISessionFactory SessionFactory { get { return _sessionFactory; } set { _sessionFactory = value; } } private BL() { SessionFactory = Dal.SessionFactory.CreateSessionFactory(); } private object thisLock = new object(); private BL _instance = null; public BL Instance { get { lock (thisLock) { if (_instance == null) { _instance = new BL(); } return _instance; } } } } As far as I know, when I address the Instance BL object in the BL class for the first time, it should load the constructor and that should initialize the SessionFactory object. But when I try : BL.Instance.SessionFactory.OpenSession(); I get a Null Reference Exception, and I see that SessionFactory is null... why?
