  • Html.ActionLink in a button

    - by Pomster
    I Am trying to connect to a method in my controller, with a button. I can connect though this link: @Html.ActionLink("Print", "Print", new { id = Model.SalesContractId}) But i Don't want a link, i want my button on my dialog to do it. I have tried the following: $('#btnDialogPrint').click(function () { location.href = '<%= Url.Action("Print", "Print", new { id = Model.SalesContractId}) %>'; }); But it just redirect me to a page that say bad request. namespace Contract.Controllers { public class ContractController : Controller { CompassEntities db = new CompassEntities(); public ActionResult Print(int id) { return View(""); // This can be removed and Print code may be added } Don't worry about the code inside i will get to that once i get inside this method. Could i maybe attach a link here? <input type="button" value="Print" id="btnDialogPrint" />

  • Find and sort by number of ocurrences of tag with Active Admin and act_as_taggable_on

    - by nunopolonia
    I'm using act_as_taggable_on and Active Admin on a Rails project. In that project there are Posts and each Post has Tags. I want to show a list of Tags in Active Admin and the number of ocurrences of each one. The way I found to do this was: index do column :name column :ocurrences do |tag| ocurrences = Post.tag_counts.find(tag.id).count end default_actions end Which will search the Tag List every time for every Post, which performance wise looks really bad. I would also like to be able to sort the tags by ocurrence. Any idea of how I can do it?

  • How do I make a serilaization class for this?

    - by chobo2
    Hi I have something like this(sorry for the bad names) <root> <product></product> <SomeHighLevelElement> <anotherElment> <lowestElement> </lowestElement> </anotherElment> </SomeHighLevelElement> </root> I have something like this for my class public class MyClass { public MyClass() { ListWrapper= new List<UserInfo>(); } public string product{ get; set; } public List<SomeHighLevelElement> ListWrapper{ get; set; } } public class SomeHighLevelElement { public string lowestElement{ get; set; } } But I don't know how to write the code for the "anotherElement" not sure if I have to make another wrapper around it.

  • What's the most efficient way to manage large datasets with Javascript/jQuery in IE?

    - by RenderIn
    I have a search that returns JSON, which I then transform into a HTML table in Javascript. It repeatedly calls the jQuery.append() method, once for each row. I have a modern machine, and the Firefox response time is acceptable. But in IE 8 it is unbearably slow. I decided to move the transformation from data to HTML into the server-side PHP, changing the return type from JSON to HTML. Now, rather than calling the jQuery.append() time repeatedly, I call the jQuery.html() method once with the entire table. I noticed Firefox got faster, but IE got slower. These results are anecdotal and I have not done any benchmarking, but the IE performance is very disappointing. Is there something I can do to speed up the manipulation of large amounts of data in IE or is it simply a bad idea to process very much data at once with AJAX/Javascript?

  • TFS as source-control: what do you love? what do you hate?

    - by jcollum
    I've used TFS for about 18 months now and I'm really not excited about it. It seems like the worst of the current versions of SCMs on the market. I think this thread will help people decide if TFS is for them vs. other source control systems. While TFS does a lot more than that, I think that source control is so critical to software development that any system (or combination thereof) that you pick needs to consider source control first. What are the good things about TFS vs. other source controls -- what does it do well that no one else does? What are the things that TFS is bad at that everyone else seems to do just fine?

  • Rails associations of user/post/comment

    - by garthcn
    Hi, I'm trying to create an app like a blog, with 3 models: user, post and comment. As expected, a comment belongs to both a user and a post. I used the following associations: User.rb has_many :comments has_many :posts Post.rb has_many :comments belongs_to :user Comment.rb belongs_to :user belongs_to :post And I tried to create comments using: @user.comments.create However, this will relate the comment with user, but not with post. I want the comment to be associated wit BOTH user and post. Is there a way to do so? Or did I use the wrong associations? I think it might be a bad practice to set the user_id or post_id by hand, so both ids are not in attr_accessible. I'm not sure if it is correct. Thank you!

  • How to Change Type of a VARIANT

    - by nimo
    Hi, I'm having a VARIANT with its type set to VT_R8. Subsequently I need to change its type to VT_BSTR. I would like know whether there is a way of resetting a VARIANT status. Thus, I noticed that every time I set value to the VARIANT (in my case, its double) , VARIANT itself set its bstrVal member to a bad pointer, even though I set bstrVal member to NULL at the initialization of VARIANT. Why such thing is happening ? Is it safe to use a VARIANT as structure where both dbVal and bstrVal member are set ? Please clarify, thank you.

  • Select where a value present

    - by Roy
    First a database example: id, product_id, cat, name, value -------------------------------- 1,1,Algemeen,Processor,2 Ghz 2,1,Algemeen,Geheugen,4 GB 3,2,Algemeen,Processor,3 Ghz 4,2,Algemeen,Geheugen,4 GB 5,3,Beeldscherm,Inch,22" 6,3,Beeldscherm,Kleur,Zwart 7,3,Algemeen,Geheugen,3 GB 8,3,Algemeen,Processor,3 Ghz I want with one query to select the follow id's: 1,2,3,4,7,8 Because the cat = algemeen and the name = processor by these products. ID 5,6 are only present by product 3. So, the entry's (cat and name) which are present by all products (product_id) have to be selected. The database contains 80.000 entry's with a lot of diffrent cat's, name's and value's. Is this possible with one query or is some php necessary? How do I do this? My apologies for the bad English.

  • Please help me with this Ruby code

    - by Bragaadeesh
    Hi, I am new to Ruby and I know that I am not using the simple and powerful methods available within it. I made my code work but it has to be simple not this huge (especially I feel I am very bad at loop variables) i = 0 j = 0 loop_count = ((to_date-from_date)/(60*60*24)).to_i#diff b/w two dates in days loop_count.times do 48.times do event = Icalendar::Event.new status = get_availability_on_date_and_hour(@templates, @availabilities, from_date+j.days, i).downcase if(status != 'unavailable') #Initialize start and end dates in DateTime's civil format bias_date_time = DateTime.civil(from_date.year, from_date.month, from_date.day) event.dtstart = bias_date_time + j.day + (i/2).to_i.hour + (i%2*30).to_i.minutes event.dtend = event.dtstart + 30.minutes event.summary = status.upcase cal.add_event(event) end i += 1 end i = 0 j += 1 end

  • If you had to work with horrible HTML, what would you do?

    - by Doug
    I was looking over some of my friend's HTML and CSS, and I was speechless (in a bad way). If I had to work with that, such as putting AJAX into it, then it would have been a lot of work. I would have to rebuild a lot of the HTML aspects, otherwise it wouldn't work well with the AJAX. What would you do in a situation like so? Would you just edit at the minimum? Would you do a overhaul and redo the whole HTML aspect? Would you go back to the client and ask for more money because it was a lot more work than expected? I'm interested in strategies and approaches and how it's done out in the field.

  • mysql_num_rows(): supplied argument is not a valid MySQL result resource

    - by php-b-grader
    I am getting this error when I pass an invalid SQL string... I spent the last hour trying to find the problem assuming - It's not my SQL it must be the db handle... ANyway, I've now figured out that it was bad SQL... What I want to do is test the result of the mysql_query() for a valid resultset. I am simply using empty($result)... Is this the most effective test? Is there a more widely accepted method of testing a resultset for a valid result?

  • Should I convert overly-long UTF-8 strings to their shortest normal form?

    - by Grant McLean
    I've just been reworking my Encoding::FixLatin Perl module to handle overly-long UTF-8 byte sequences and convert them to the shortest normal form. My question is quite simply "is this a bad idea"? A number of sources (including this RFC) suggest that any over-long UTF-8 should be treated as an error and rejected. They caution against "naive implementations" and leave me with the impression that these things are inherently unsafe. Since the whole purpose of my module is to clean up messy data files with mixed encodings and convert them to nice clean utf8, this seems like just one more thing I can clean up so the application layer doesn't have to deal with it. My code does not concern itself with any semantic meaning the resulting characters might have, it simply converts them into a normalised form. Am I missing something. Is there a hidden danger I haven't considered?

  • UITableViewController executes delate functions before network request finishes

    - by user1543132
    I'm having trouble trying to populate a UITableView with the results of a network request. It seems that my code is alright as it works perfectly when my network is speedy, however, when it's not, the function - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath- still executes, which results in a bad access error. I presume that this is because the array that the aforesaid function attempts to utilize has not been populated. This brings me to my question: Is there anyway that I can have the UITableView delegate methods delayed to avoid this? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"AlbumsCell"; //UITableViewCell *basicCell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath]; AlbumsCell *cell = (AlbumsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { **// Here is where the Thread 1: EXC_BAD_ACCESS (code=2 address=0x8)** cell = [[[AlbumsCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } Album *album = [_albums objectAtIndex:[indexPath row]]; [cell setAlbum:album]; return cell; }

  • Why is numpy c extension slow?

    - by Bitwise
    I am working on large numpy arrays, and some native numpy operations are too slow for my needs (for example simple operations such as "bitwise" A&B). I started looking into writing C extensions to try and improve performance. As a test case, I tried the example given here, implementing a simple trace calculation. I was able to get it to work, but was surprised by the performance: for a (1000,1000) numpy array, numpy.trace() was about 1000 times faster than the C extension! This happens whether I run it once or many times. Is this expected? Is the C extension overhead that bad? Any ideas how to speed things up?

  • Identifying when there is more than 1 in a group based on grouped field

    - by Brian Cascone
    Sorry for the bad description it is tough to explain in one sentence. I have a dataset that has Cause field (RootCause) and an ID field (GroupID). Both can be many things but I need to identify where a GroupID has a multiple different rootcauses. for example: RootCause GrpId AAA 111 BBB 222 CCC 111 I am looking to be able to identify that GrpId 111 has two different RootCauses. This is what I have so far: Select [RootCause], GrpId, Count(GrpID) as CntGrpId From DB.dbo.Table Where DatatypeField <> '' Group BY [RootCause],GrpId This results set visualy gives me enough information to identify what I am looking for, but i need something better. I am looking to return only the ones that have multiples. Any ideas? Thanks

  • Prevent .htaccess syntax error

    - by seengee
    Hi, As part of one our system's we enable a user in the backoffice to add a block of 301 redirects should they need to. This is just a textarea which then populates a specific area of a .htaccess file. As much as this may seem insecure it has only previously used internally by people who know what they are doing but for various reasons they cannot access the specific file. We need now to allow more access to this function, not for the general public, but for people that probably have far less knowledge of regexp etc and syntax in htaccess files. Obviously the major concern here is the user enters some bad syntax and makes their entire site, including the backoffice where they could fix the issue, totally inaccessible without manual intervention. What approaches can i take to make sure that they do not break their site? A htaccess syntax check? copy the file elsewhere and check it doesnt generate a 500 error (with cURL or similar)?. Would welcome any ideas. Thanks.

  • Putting logic in ViewModel get'ers

    - by Yngvebn
    What do you think about putting Get-logic in the getters of a ViewModel? Something like: public class DummyViewModel { public int Id { get; set; } private DummyObject myObject; public DummyObject MyObject { get { if (MyObject == null) { DummyRepository repo = new DummyRepository(); myObject = repo.Get(Id); } return myObject; } } } Is this bad practice, or totally fine? I find my controllers getting really bloated by doing all the get-logic there, but I'm really torn as to where I should put it... My reason for doing it this way, is that I can pass the ViewModel to different types of view, and only the neccessary DB-lookup will be performed based on what property is requested.

  • Should I combine unrelated interfaces into a single library?

    - by mafutrct
    Situation is like this: There are independent 5 services. Each service consists of a project for interface, implementation and test. Example: LocalizationService.Interfaces LocalizationService.Implementation LocalizationService.Test There is a WCF service for each of the services: LocalizationService.WcfContract (including DataContracts) LocalizationService.WcfHost The client applications are probably mostly going to use all of the services. Should I combine all service interfaces into a common one? AllServices.AllInterfaces In my opinion, this is a bad idea. The services are independent and there is no reason to introduce a dependency. I imagine that especially testing becomes more difficult. However, one may argue that having to include 5 libraries is too much of a hassle. (I'm not sure how to tag this. Feel free to retag.)

  • Sql Server 2000 Stored Procedure Prevents Parallelism or something?

    - by user187305
    I have a huge disgusting stored procedure that wasn't slow a couple months ago, but now is. I barely know what this thing does and I am in no way interested in rewriting it. I do know that if I take the body of the stored procedure and then declare/set the values of the parameters and run it in query analyzer that it runs more than 20x faster. From the internet, I've read that this is probably due to a bad cached query plan. So, I've tried running the sp with "WITH RECOMPILE" after the EXEC and I've also tried putting the "WITH RECOMPLE" inside the sp, but neither of those helped even a little bit. When I look at the execution plan of the sp vs the query, the biggest difference is that the sp has "Parallelism" operations all over the place and the query doesn't have any. Can this be the cause of the difference in speeds? Thank you, any ideas would be great... I'm stuck.

  • Functions without arguments, with unit as argument in scala

    - by scout
    def foo(x:Int, f:Unit=>Int) = println(f()) foo(2, {Unit => 3+4} //case1 def loop:Int = 7 foo(2, loop) //does not compile changing loop to //case 2 def loop():Int = 7 foo(2, loop) // does not compile changing loop to //case 3 def loop(x:Unit): Int = 7 //changing according to Don's Comments foo(2,loop) // compiles and works fine should'nt case 1 and case 2 also work? why are they not working? defining foo as def foo(x:Int, y:()=>Int) then case 2 works but not case 1. Arent they all supposed to work, defining the functions either way. //also i think ()=Int in foo is a bad style, y:=Int does not work, comments??

  • Snapping elements / conditional layouts

    - by Felix
    Sorry for the extremely bad title, I have no other idea what to call this question. What I'm trying to do is this: have a RelativeLayout which has two children: one with layout_centerInParent="true" one with layout_alignParentBottom="true" However, when the device is in landscape mode, element (1) appears slightly over or under element (2). But, element (1) has enough space above it to appear above element (2). How could I make the layout so that if the screen is too small to center element (1) and make both elements not overlap, then align element (1) above (as in layout_above) element (2)?

  • MVC2 JSON action, if I want to be RESTful should I allow GET, POST, or Both?

    - by Yads
    The project I'm currently working has a whole bunch of JSON actions in order to populate cascading dropdowns via ajax calls. Since they're technically Select queries and we're trying to be RESTful, we've been marking these actions with the HttpGet attributes. However by default, JsonResultdoes not allow to return results via a GET. So we've had to explicitly call Json(data, JsonRequestBehavior.AllowGet). What I'm wondering is, is this bad practice? Should we only be allowing Post requests to our Json actions? If it makes a difference, this is an enterprise application, that requires a log in to a particular environment before it can be accessed.
