• NSMutableArray with only a particular type of objects

  - by Leo

  Hello, is it possible to specify that a NSMutableArray can only contain a certain type of objects. For example, if I want to store only this kind of objects : @interface MyObject : NSObject { UInt8 value; } In order to be able to use the instance variable like this : - (void)myMethod:(NSMutableArray *)myArray{ for (id myObject in myArray){ [self otherMethod:myObject.value]; } } because I'm getting this error : request for member 'value' in something not a structure or union Thank you for your help

• When to use std::size_t?

  - by nhaa123

• iphone facebook framework

  - by satyam

  i'm able to successfully integrate facebook into my iphone application. but just before publishing, it will show a dialog which is an instance of "FBStreamDialog". I'm only setting "userMessagePrompt" which is "Share the app with Facebook and follow the link to obtain the app" and "attachment" with "Share the app". When the app is run and when FBStreamDialog is shown, I'm seeing only "attachment" and not "userMessagePrompt". Why?

• Javascript unable to pass parameters into a property acting as a function

  - by BOverflow

  Currently in a simplified form, my code looks like this function AddFileParam(file_id, name, value) { uploadcontrol.addFileParam(file_id, name, value) } uploadcontrol = new Upload() function upload() { //logic } upload.prototype.AddFileParam = function(file_id, name, value) { //logic }; The code is giving me an error as it states that addFileParam is not a valid function. This is caused by the instance of the function upload (aka. uploadcontrol). This is only occuring in Firefox/Chrome and not in IE. Any ideas on how to fix this?

• Python: how to inherite and override

  - by Guy

  Consider this situation: I get an object of type A which has the function f. I.e: class A: def f(): print 'in f' def h(): print 'in h' and I get an instance of this class but I want to override the f function but save the rest of the functionality of A. So what I was thinking was something of the sort: class B(A): .... def f(): print 'in B->f' and the usage would be: def main(a): b = B(a) b.f() #prints "in B->f" b.h() #print "in h" How do you do such a thing?

• nHibernate: limit the result set of a mapped collection

  - by HeavyWave

  How do you limit the result set of a mapped collection in nHibernate? For instance: Model.Items; will always return all the Items for the given Model. Is there any way to force it to return only, say, 20 Items without creating a specific query ? Something like Model.Items.SetMaxResults(20); In other words, I would like nHibernate to return IQueryable instead of a simple IList, when I access a collection.

• How to select records as columns in SQL

  - by Leigh

  Hi, I have two tables: tblSizes and tblColors. tblColors has columns called ColorName, ColorPrice and SizeID. There is one size to multiple colors. I need to write a query to select the size and all the colors (as columns) for a that size with the price of each size in its respective column. The colors must be returned as columns, for instance: SizeID : Width : Height : Red : Green : Blue 1---------220-----220----£15----£20-----£29 Hope this makes sense Thank you

• Is there simple way how to join two RouteValueDictionary values to pass parameters to Html.ActionLin

  - by atagaew

  Hi. Look on my code that i created in a partial View: <% foreach (Customer customerInfo in Model.DataRows) {%> <tr> <td> <%=Html.ActionLink( customerInfo.FullName , ((string)ViewData["ActionNameForSelectedCustomer"]) , JoinParameters(customerInfo.id, (RouteValueDictionary) ViewData["AdditionalSelectionParameters"]) , null)%> </td> <td> <%=customerInfo.LegalGuardianName %> </td> <td> <%=customerInfo.HomePhone %> </td> <td> <%=customerInfo.CellPhone %> </td> </tr> <%}%> Here I'm building simple table that showing customer's details. As you may see, in each row, I'm trying to build a link that will redirect to another action. That action requires customerId and some additional parameters. Additional parameters are different for each page where this partial View is using. So, i decided to make Action methods to pass that additional parameters in the ViewData as RouteValueDictionary instance. Now, on the view i have a problem, i need to pass customerId and that RouteValueDictionary together into Html.ActionLink method. That makes me to figure out some way of how to combine all that params into one object (either object or new RouteValueDictionary instance) Because of the way the MVC does, i can't create create a method in the codebehind class (there is no codebihind in MVC) that will join that parameters. So, i used ugly way - inserted inline code: ...script runat="server"... private RouteValueDictionary JoinParameters(int customerId, RouteValueDictionary defaultValues) { RouteValueDictionary routeValueDictionary = new RouteValueDictionary(defaultValues); routeValueDictionary.Add("customerId", customerId); return routeValueDictionary; } ...script... This way is very ugly for me, because i hate to use inline code in the View part. My question is - is there any better way of how i can mix parameters passed from the action (in ViewData, TempData, other...) and the parameter from the view when building action links. May be i can build this link in other way ? Thanks!

• does the object creating a sub appdomain get instantiated in that sub appdomain?

  - by Eric

  does the object creating a sub appdomain get instantiated in that sub appdomain? I have an object that is in the main AppDomain and it is creating another AppDomain and it requires the calling class to be serializable and is creating an instance of the calling class in the new sub AppDomain. I'm wondering if that is how it is, or if there is a way that I can create the sub appDomain but still hold on to the original instantiation of the calling object in the main appDomain

• What's the workflow of Continuous Integration With Hudson?

  - by Satoru.Logic

  Hi, all. I am referred to Hudson today. I have heard about continuous integration before, but I have no idea what the heck is a ci-server. Hudson is really easy to install in Ubuntu and in several minutes I managed to set up an instance of it. But I don't quite understand the workflow of a ci-server, or how am I supposed to use it? Please tell me if you have experience about ci, thanks in advance.

• Using the standard Flash AS3 scrollbar class

  - by WebDevHobo

  Flash has a scrollbar class, documented here: http://help.adobe.com/en_US/AS3LCR/Flash_10.0/fl/controls/ScrollBar.html However, besides listing functions and variables, there's no real explanation of how to hook an instance of this class to a textfield. Everything I've tried either ends up in errors or the scrollbar not showing. The documentation lacks a clear way of how you should bind the textfield and the scrollbar toghether, and CS4 isn't providing any help either. Can someone explain, or link to an example of how scrollbars work with textfield?

• code style for private methods in c#

  - by illdev

  I just found out, that it seems a common pattern to user UpperFirstLetterPascalCase() for private methods. I for myself, find this completely inconsistent with naming rules of private instance fields and variables and I find it difficult to read/debug, too. I would want to ask, why using a first upper letter for methods could be a better choice than a first lower (doThis())? Just out of curiosity...

• Finding partial substrings within a string

  - by Peter Chang

  I have two strings which must be compared for similarity. The algorithm must be designed to find the maximal similarity. In this instance, the ordering matters, but intervening (or missing) characters do not. Edit distance cannot be used in this case for various reasons. The situation is basically as follows: string 1: ABCDEFG string 2: AFENBCDGRDLFG the resulting algorithm would find the substrings A, BCD, FG I currently have a recursive solution, but because this must be run on massive amounts of data, any improvements would be greatly appreciated
