• MVC Html Layout C# code formatting

  - by Andrew Florko

  I insert into asp.net mvc views C# logic that manages layout like the following: <% if (Model.People.Count > 0 ) { %> <% foreach (var person in Model.People) { %> ... <% }} else { %> <span class="error">Sorry, no people</span> <%} %> I try to minimize <% % code placing "{" symbol on the same line as it's condition (java-style). Html layout looks more clear to me after that. Do you apply C# formatting rules to <% % html injections "}" should be on a new line or manage layout in different way? Thank you in advance!

• XML DOM Manipuation

  - by kunalsawlani

  Hi, I am new to XML and have been trying some simple examples and they work fine. I want to do something like the following, but I am not able to figure out how to go about doing this. I have a HTML web page, where the user types in some data in an input field. I want to take that data, parse it to create an XML string, and the apply XSLT transformation to it, and display the result back on the page. All this needs to be done on the client browser, with JavaScript. If some one could point out the steps or the general procedure to go about doing this, it would be great. I have been looking over the net, but the information is so vast, that I have not been able to locate exactly what I need. Thanks

• IE - Color transparent not working

  - by poru

  Hello, I have a problem with the IE (what else?): I generate content with CSS which has also a background-image. I looks like that: #nav ul li:after { content: "--"; position: relative; z-index: 99; background: transparent url(image.png); color: transparent; } The text color is in non-IE-browsers transparent, but in all IE browsers it's black and you could see it. How could I make the text transparent/unvisible? I tried already: visibility - opacity - filter - text-indent ... But none did his job right, either it disappears (with it background which I need) or the attribute doesn't apply.

• How to lowercase every element of a collection efficiently?

  - by Chris

  Whats the most efficient way to lower case every element of a list or set? My idea for a List: final List<String> strings = new ArrayList<String>(); strings.add("HELLO"); strings.add("WORLD"); for(int i=0,l=strings.size();i<l;++i) { strings.add(strings.remove(0).toLowerCase()); } is there a better, faster way? How would this exmaple look like for a set? As there is currently no method for applying an operation to each element of a set (or list) can it be done without creating an additional temporary set? Something like this would be nice: Set<String> strings = new HashSet<String>(); strings.apply( function (element) { this.replace(element, element.toLowerCase();) } ); Thanks,

• Applying a function with multiple inputs using Map? (Haskell)

  - by Schroedinger

  G'day guys, Trying currently to finish up a bit of homework I'm working on, and having an issue where I'm trying to apply map across a function that accepts multiple inputs. so in the case I'm using processList f (x:xs) = map accelerateList f xs x xs processList is given a floating value (f) and a List that it sorts into another List Accelerate List takes a floating value (f) a List and a List Object through which it returns another List Object I know my Accelerate List code is correct, but I cannot for the life of me get the syntax for this code working: processList :: Float -> [Object] -> [Object] accelerate f [] = [] accelerate f [x] = [(accelerateForce f x x)] accelerate f (x:xs) = map accelerateList f xs x xs Any ideas? I've been scratching my head for about 3 hours now. I know it's something really simple.

• Poster image on embedded youtube video

  - by Srijan Deshpande

  Hi, I want to embed a youtube video on my website and I need to replace the default poster image that shows up on the video with a jpg of my own. The default image that shows up is a scaled-up thumbnail and is therefore very blurry and pixelated and I need to use a hi-res jpg in place of it. I'm aware that youtube only allows us to pick one of three auto-generated thumbnails, but does that restriction also apply to youtube videos embedded on an external website? If so, is there an alternate way to do this? Thanks!

• Ownership regarding to returned Quartz objects

  - by huggie

  I have recently asked about autoreleasing a returned quartz object: http://stackoverflow.com/questions/2819548/autorelease-for-cgmutablepathref Dave DeLong answered my question that there is no autorelease for quartz (or any NS foundation objects) and I should use the Create Rule. However the naming convention on the document says, The Core Foundation naming conventions, in particular use of the word “create”, only apply to C functions that return Core Foundation objects. Naming conventions for Objective-C methods are governed by the Cocoa conventions, irrespective of whether the method returns a Core Foundation or Cocoa object. By this account since my function is a message in an objective C object it doesn't seem proper to name it createSomething. I still want to return this object. What's the best way to approach this? Should I use the Get Rule and then have the caller explicitly retain it? But this is not within Cocoa convention. What's the proper way to handle this?

• Actionscript blur/shadows/glows how heavy are they on the processor?

  - by Fahim Akhter

  Hi, I have say 10 items in a particular space, If I apply glows and drop shadows to all of them and all of these items are usually static. Other characters do move around them too. So I'm just wondering would it be wise to use vectors with actionscript blurs and glows. Or to have a PNG? and if I cannot have a PNG and have to work with vectors with glows/blurs/shadows. Would they be too heavy on the processor?

• div with float next to div with width

  - by dragonfly

  Hi, I have html: <div class="field-label"><label>Email: </label></div> <div class="field"><input class="input" ......></div> and piece of css: .field-label { clear:left; float:left; padding:0.5em; width:6em; } .field { padding:0.5em; } And it worked fine. But for some elements I wanted to apply following change: when I add width to .field class layout goes to blazes: element with .field class appears under element with field-label class. Container of whole form is width enough to hold elements with field-label & field class. Why is it happening, did I miss something in css basics? Thanks ,Pawel

• How to skip the invalid rows while inserting the data into Database

  - by Dinesh

  We have a statement., that is inserting some rows in a temporary table (say e.g., 10 rows), while inserting 5th row, it has some issue with one of the column format and giving an error and then it stopped inserting the rows. What I want is, it should skip the error rows and insert valid rows. For those error rows, it can skip that error column and insert with some null value & different status. create table #tb_pagecontent_value (pageid int,formid uniqueidentifier, id_field xml,fieldvalue xml,label_final xml) … … insert into #tb_pagecontent_xml select A.pageid,B.formid,A.PageData.query('/CPageDataXML/control') from Pagedata A inner join page B on A.PageId=B.PageId inner join FormAssociation C on B.FormId=C.FormId where B.pageid in (select pageId from jobs where jobtype='zba' and StatusFlag!=1) in the above e.g., I want to apply that logic. Any help is appreciated.

  - by Zia ur Rahman

  Hay dear! Suppose we want to make a software , we want to automate the system of university. Suppose a student apply in the university for a certain course, now the question is where the application form of the student will go and what process will be done on this form and then what is the next stage of this form and why it will go to the next stage? Now I hope you have got my point. I need information from the enrollment of a student to its pass out. Or provide a state transition diagram or Data flow diagram. I will be very thankful.

• How do I write a scheme macro that defines a variable and also gets the name of that variable as a s

  - by Jason Baker

  This is mostly a follow-up to this question. I decided to just keep YAGNI in mind and created a global variable (libpython). I set it to #f initially, then set! it when init is called. I added a function that should handle checking if that value has been initialized: (define (get-cpyfunc name type) (lambda args (if libpython (apply (get-ffi-obj name libpython type) args) (error "Call init before using any Python C functions")))) So now here's what I want to do. I want to define a macro that will take the following: (define-cpyfunc Py_Initialize (_fun -> _void)) And convert it into this: (define Py_Initialize (get-cpyfunc "Py_Initialize" (_fun -> _void))) I've been reading through the macro documentation to try figuring this out, but I can't seem to figure out a way to make it work. Can anyone help me with this (or at least give me a general idea of what the macro would look like)? Or is there a way to do this without macros?

• Stable separation for two classes of elements in an array

  - by AndreyT

  Consider the following problem. We are given an array of elements belonging to one two classes: either red or blue. We have to rearrange the elements of the array so that all blue elements come first (and all red elements follow). The rearrangement must be done is stable fashion, meaning that the relative order of blue elements must be preserved (same for red ones). Is there a clever algorithm that would perform the above rearrangement in-place? A non-in place solution is, of course, straightforward. An obvious in-place solution would be to apply any stable sorting algorithm to the array. However, using a full-fledged sorting algorithm on an array intuitively feels like an overkill, especially taking into account the fact that we are only dealing with two classes of elements. Any ideas greatly appreciated.

• .NET Framework - When to Upgrade?

  - by Andrew

  I’m faced with a challenge of leading two (currently) separate .NET development groups with different development strategies. One group is developing on the .NET Framework 2.0 (with maybe a few applications on 3.5). The other group immediately adopts any new framework that comes out, and begins coding any new applications with it (they are running 2.0-4.0 applications). For this last group, applications written in an earlier version than the latest framework do not get upgraded. What is the current school of thought when it comes to a company developing web applications on when to adopt a new framework, and whether to migrate applications built on previous versions to the latest framework or not? Years ago the thought was to wait until the technology became mainstream - but that doesn't seem to apply much now with .NET.

• Best way to do syntax highlighting in GTK+?

  - by Tyler

  I was wondering if someone could point me to an example of (or just their thoughts on) the best way to code syntax highlighting in a C-based GTK+ application. I know that I can use the GtkTextTag to modify text in a GtkTextBuffer but beyond searching out keywords (iteratively or by regexing the string) is there a better way? My only concern is that if I wipe all of the tags and then re-search and apply the tags at every text change event it could really bog down my application. As always thanks for your help!

• Most efficient way for a lookup/search in a huge list (python)

  - by user229269

  Hey guys, -- I just parsed a big file and I created a list containing 42.000 strings/words. I want to query [against this list] to check if a given word/string belongs to it. So my question is: What is the most efficient way for such a lookup? A first approach is to sort the list [list.sort()] and then just use the if word in list: print 'word' -- which is really trivial and I am sure there is a better way to do it. My goal is to apply a fast lookup that finds whether a given string is in this list or not. If you have any ideas of another data structure, they are welcome. Yet, I want to avoid for now more sophisticated data-structures like Tries etc. I am interested in hearing ideas (or tricks) about fast lookups or any other python library methods that might do the search faster than the simple 'in'. Thanks in advance!

• Using Selenium to Determining The Visibility of Elements for Print media

  - by Tom Howard

  I would like to determine if particular elements on a page are visible when printed as controlled by CSS @media rules. Is there a way to do this with Selenium? I know there is the isDisplayed method, which takes the CSS into account, but there is nothing I can find to tell Selenium which media type to apply. Is there a way to do this? Or is there another way to test web pages to make sure the elements you want are printed (and those you don't aren't)? Update: For clarity, there are no plans to have a javascript print button. The users will print using the normal print functionality of the browser (Chrome, FF and IE). @media css rules will be used to control what is shown and hidden. I would like Selenium to pretend it is a printer instead of a screen, so I can test if certain elements will be visible in what would be the printed version of the page.

• SQLite not pluralizing Table Names

  - by weenet

  I am using SQLite as my db during development, and I want to postpone actually creating a final database until my domains are fully mapped. So I have this in my Global.asax.cs file: private void InitializeNHibernateSession() { Configuration cfg = NHibernateSession.Init( webSessionStorage, new [] { Server.MapPath("~/bin/MyNamespace.Data.dll") }, new AutoPersistenceModelGenerator().Generate(), Server.MapPath("~/NHibernate.config")); if (ConfigurationManager.AppSettings["DbGen"] == "true") { var export = new SchemaExport(cfg); export.Execute(true, true, false, NHibernateSession.Current.Connection, File.CreateText(@"DDL.sql")); } } The AutoPersistenceModelGenerator hooks up the various conventions, including a TableNameConvention like so: public void Apply(FluentNHibernate.Conventions.Instances.IClassInstance instance) { instance.Table(Inflector.Net.Inflector.Pluralize(instance.EntityType.Name)); } This is working nicely execpt that the sqlite db generated does not have pluralized table names. Any idea what I'm missing? Thanks.

• Sort a GridView Column related to other Table

  - by Tim

  Hello, i have a GridView bound to a DataView. Some columns in the DataView's table are foreignkeys to related tables(f.e. Customer). I want to enable sorting for these columns too, but all i can do is sorting the foreignkey(fiCustomer) and not the CustomerName. I have tried this without success(" Cannot find column ERP_Customer.CustomerName "): <asp:TemplateField HeaderText="Customer" SortExpression="ERP_Customer.CustomerName" > A tried also the DataViewManager, but i've a problem to detect the table to sort: Dim viewManager As New DataViewManager(Me.dsERP) viewManager.DataViewSettings(dsERP.ERP_Charge).RowFilter = filter viewManager.DataViewSettings(dsERP.ERP_Charge).Sort = sort 'sort is the GridView's SortExpression Me.GrdCharge.DataSource = viewManager.CreateDataView(dsERP.ERP_Charge) I have to apply the sort on a distinct table of the DataViewManager, but this table would differ on the related tables. I have bound the TemplateColumns in Codebehind in RowDataBound-Event f.e.: Dim LblCustomer As Label = DirectCast(e.Row.FindControl("LblCustomer"), Label) LblCustomer.Text = drCharge.ERP_CustomerRow.CustomerName 'drCharge inherits DataRow What is the recommended way to sort a GridView on columns related to another table?

• Websites' color scheme generators - what to do with them in real life?

  - by Marco Demaio

  On the web there are plenty of color scheme/palette generator tools and color palettes galleries. All of these tools/gelleries show many 3 to 5 colors palette as final result. Some of these tools: http://kuler.adobe.com, http://www.colorexplorer.com I know my question might sound ridicolous to someone who is involved in web dedign, but I don't understand what to do with these color palette. I mean, if I have to create a website, how am I supposed to apply this color palette to the website. Which color goes as foreground text, which one as background, which one for the links, which one for the page titles and so on? What are these color palette generators useful for then?! Thanks!

• JSF skips phases - How to debug that?

  - by Pentius

  Hey fellows, I have to debug a foreign jsf application thanks god. The problem is, that I submit a form, but the values aren't carried over. With a phase listener I can see, that the life cycle doesn't run completely through, so to say it skips phase 2 -5: After the restore view phase, the render response phase is directly called. I miss the apply values, validation, update model actions and so on. So, this could be a chicken-and-egg problem: 1. The responsible phases aren't called, so the new form input can't be carried over. 2. The system doesn't recognize any new input and therefore directly renders after restoring the view. I checked that there is no call of responseComplete() oder renderResponse(). I'm stuck somehow. Any idea to validate one of the two hypothesis? Or how to debug that in general? Did anybody have a similar problem?

• How can I require an attribute on a class definition?

  - by spoulson

  Is there a way to enforce a compile requirement for certain attributes on a class or interface implementation? For example, let's say my application uses a series of static classes that contain const int resource values. I'd like to decorate the class in a Description attribute to describe its contents. In concept, I'd like to apply this attribute requirement to an interface, then each static class would implement it with its required Description. I could write a run-time check or a unit test to check compliance. But really a compile-time check would be best. Is there such a thing?
