• RadioButtonList.SelectedIndex vs RadioButtonList.SelectedValue

  - by Pinpin

  Out of curiosity, anyone knows the particulars of the internal implementation of ListControl.SelectedIndex = (int) <new valueIndex> VS ListControl.SelectedValue = <new value>.ToString() I'm having difficulties with a custom validation object we've built here to process all validation in one sweep. I suspect using <SelectedValue = > will raise a SelectedIndexChanged event, even though both the value and index remain the same, both before and after the operation. (The ListControl's values are populated declaratively....) As ever, thank you for your time!

• How to find all Classes implemeting IDisposable?

  - by apoorv020

  I am working on a large project, and one of my tasks is to remove possible memory leaks. In my code, I have noticed several IDisposable items not being disposed of, and have fixed that. However, that leads me to a more basic question, how do I find all classes used in my project that implement IDisposable? (Not custom created classes by normal Library classes). I have already found one less-than-obvious class that implements IDisposable ( DataTable implements MarshalByValueComponent, which inherits IDisposable). Right now, I am manually checking any suspected classes by using MSDN, but isn't there some way through which I can automate this process?

• Ninject Given Path's format is not supported

• Wordpress Video Portal

  - by choise

  Hi out there, my challenge is to built a video portal, based on wordpress (blog already started). so in the backend there must be a option to add, tag, descripe videos and in frontend the videos must have a comment function, must be searchable and so on. wordpress gives already a large amout of functionallity and i want to use this, comments for example, but also categorisation and tagging. what is the best practise to built such a "plugin" ? where to start? what to use? custom tables and built everything by myself or can i use the blog functionallity to advantage? hopefully everything is clear, comment if not ;)

• Deploying site pages in SharePoint

  - by Faiz

  Hi, I have around 9 web parts and 3 pages to be deployed. Each page will be having 3 webparts. From a deploymnet perspective, i think i have the following two options: Deploy the pages using a feature. The pages will have webparts present. Create a custom site definition with a document library and have the three pages as part of the document library. Can you please let me know which one of the options is better or is there any better solution?. Please note that the solution needs to work on WSS 3.0 as well.

• NHybernate, the Parallel Framework, and SQL Server

  - by andy

  hey guys, we have a loop that: 1.Loops over several thousand xml files. Altogether we're parsing millions of "user" nodes. 2.In each iteration we parse a "user" xml, do custom deserialization 3.finally, in each iteration, we send our object to nhibernate for saving. We use: .SaveOrUpdateAndFlush(user); This is a lengthy process, and we thought it would be a perfect candidate for testing out the .NET 4.0 Parallel libraries. So we wrapped the loop in a: Parallel.ForEach(); After doing this, we start getting "random" Timeout Exceptions from SQL Server, and finally, after leaving it running all night, OutOfMemory unhandled exceptions. I haven't done deep debugging on this yet, but what do you guys think. Is this simply a limitation of SQL Server, or could it be our NHibernate setup, or what? cheers andy

• How to Detect Right Click on the Taskbar

  - by Zay

  I've got a Windows Forms application in C# that starts off with a loading dialog. As expected, a button for the app shows up in the Windows taskbar. I would like to detect right-clicks that might be done to that button. Ultimately, I hope to disable the right-click or simply have the loading dialog regain focus. I've seen that some people use custom libraries and packages (interop, for example) to achieve some Win32 functionality, but I'd personally like to avoid this. Is it impossible to do without such libraries/packages?

• How do I create email addresses for DotNetNuke users using my domain ([email protected]

  - by rwain

  My client wants to create email addresses for all their dotnetnuke users using their domain. The point is to keep the user's email addresses 'private' while still allowing communication through a public email address that they can control. It's not necessary to have a full webmail interface (although that would be nice). I'm thinking it would be enough just to forward any mail on and just act as a gateway. So if an email was sent to [email protected], it would be forwarded on to the email address associated with the dotnetnuke account with username 'rwain'. Is this possible to do in a shared hosting environment? Or do I need to create some custom mail server that does a conversion of the email address and forwards it?

• Adding relative path for an external graphic in a XSL document?

  - by Pran

  Hi, first of, I don't know much about XSL. I am using a app called DITA to generate pdfs. One of the things it requires is an overwrite of an xsl file; to add custom styling. I am trying to add an external graphic using a relative path. It doesn't work, unless I supply the full path. Does not work: <fo:block text-align="center" width="100%"> <fo:external-graphic src="../../images/logo.png"/> </fo:block> Does work: <fo:block text-align="center" width="100%"> <fo:external-graphic src="/absolute/path/to/images/logo.png"/> </fo:block> I looked on the web, it said to use "file:image.png" and other website said to use "url(image.png)", but neither worked. What am I doing wrong?

• Dynamic case statement in bash

  - by infra.user

  Hi folks, I'm trying to figure out how to create a dynamic case statement in a bash script. For example, let's say I have the output of an awk statement with the following contents red green blue In this scenario, the output can change at any time. I'm trying to then execute different logic if a value is included in this awk output. So if the data above is in $list, then I'd conceptually like to do something like: case "${my_var}" in $list) ..... something_else) ..... esac I'm trying to use this to build a dynamic custom tab completion function (see http://www.debian-administration.org/article/An_introduction_to_bash_completion_part_2 for some background). Any ideas? Thanks.

• Building a Com addin for Office 2000 / Office 2007

  - by Stuart

  I am struggling to find a straight forward guide to creating office addins using VSTO and VB.net. Specifically I would like to know how to be able to create a addin/ dll which can either be referenced from VBA in the form:- Addin.method(argument) or Addin.property = X Or which would install its own custom toolbars/ ribbon interface to an aspect of office for example Word. I've checked MSDN and in terms of legibility and usability of the explanations I have drawn a blank so far. I currently have a requirement to create at least one addin for Office 2000 to run and manipluate SQL and then a suite of addins for a customized Office 2007 (Word) set-up.

• How to get real Integer Overflows in Matlab/Octave

  - by marvin2k

  Hi there. I'm working on a verification-tool for some VHDL-Code in Matlab/Octave. Therefore I need datatypes which generate "real" overflows: intmax('int32') + 1 ans = -2147483648 Lateron, it would be helpfull if i can define the bitwidth of a variable... But that is not so important... When I build a C-like example, where a variable gets increased until it's smaller than zero, it spins forever and ever... test = int32(2^30); while (test > 0) test = test + int32(1); end Another approach i tried was a custom "overflow"-routine which was called everytime after a number is changed. This approach was painfully slow, not practicable and not working in all cases at all...

• Android programmatically add buttons to layout from string array

  - by Luke Batley

  Does anyone know how to programatically add buttons to the layout from an array? I have an array of titles and icons that i have used for a list view and now i'm wanting to reuse the same arrays to create a layout as displayed here so the layout adds a button for each item in the array and arranges them in 3's according to device width. is this possible to do? I have tried using a custom Array Adapter to generate the Grid but getting a null pointer error at the point menuGrid = (GridView) findViewById(R.id.gridView1); MenuItemsSetup menuData[] = new MenuItemsSetup[] { new MenuItemsSetup(R.drawable.ic_menu_icon1, "menuItem1"), new MenuItemsSetup(R.drawable.ic_menu_icon2, "menuItem2"), new MenuItemsSetup(R.drawable.ic_menu_icon3, "menuItem3"), new MenuItemsSetup(R.drawable.ic_menu_icon4, "menuItem4"), new MenuItemsSetup(R.drawable.ic_menu_icon5, "menuItem5"), new MenuItemsSetup(R.drawable.ic_menu_icon6, "menuItem6"), new MenuItemsSetup(R.drawable.ic_menu_icon7, "menuItem7"), new MenuItemsSetup(R.drawable.ic_menu_icon8, "menuItem8") }; String[] menuBgColours = {"#FFFFFF","#FFFFFF", ,"#888888", "#FFFFBB", "#BBFFFF","#000000", "#666666"}; CustomArrayAdapter adapter = new CustomArrayAdapter(this, R.layout.drawer_list_item, menuData, menuBgColours); menuList.setAdapter(adapter); menuGrid.setAdapter(adapter);

• What's the best way to paginate a dataset with Zend_Framework and Doctrine?

  - by joedevon

  Before I start to build this myself I thought I'd ask others to share their experience. What's the best / your favorite way to paginate a dataset with an application built upon Zend_Framework and Doctrine as your ORM? I'm new to Doctrine. I'm calling the model directly from a View Helper, bypassing the Controller, although I'm still interested if your solution uses controllers. I did see one article on this topic: http://ciaranmcnulty.com/blog/2009/06/Simplify-pagination-logic-using-a-custom-zend-paginator-adapter Devzone has an article using Doctrine, Zend Framework OR Pear, but none of those options mention a #ZF app that uses Doctrine.

• Fluent-NHibernate - Component property attributes ignored by Convention

  - by BobTodd

  I have a component with a number of properties that have various attributes Normally when these attributes are added to a plain old domain object they are picked up by my custom AttributeConventions. For the Component properties they are not. Is there some extra wiring needed for these? e.g. public class Component { [Length(Max=50)] public virtual string Name {get; set;} } public class MyClass { public virtual Component Component {get; set;} [Length(Max=50)] public virtual string Color {get; set;} } I get a table MyClass with columns Color & ComponentName Color is an nvarchar(50) whilst ComponentName is an nvarchar(255) (the default)

• google maps everytime fails to place some markers on the map

  - by Luca

  hello! im trying to place like 130/140 markers on a custom google map. i inject the map with jquery and gmaps (http://gmap.nurtext.de/) everytime, at random (not related to specific markers) a lots of markers are not shown. firebug report this error: a is null and this error comes from this file: http://maps.gstatic.com/intl/it_ALL/mapfiles/285c/maps2.api/main.js if i refresh the page...some other markers are "hidden" and other ones are shown. anyone had this problem/can help me or suggest another safe way to show all markers? thanks a lot! EDIT: this is how i inject the map and the markers (with a lots of address, but in this example only few) $(document).ready(function() { $("#container").gMap( { scrollwheel: false, maptype: G_PHYSICAL_MAP, icon: { image: "files/images/gmap_pin.png", iconsize: [32, 37], iconanchor: [32, 37], infowindowanchor: [12, 0] }, address: "Milano", zoom: 4, markers: [ { address: "Viale Certosa, Milano" }, { address: "Viale Ceccarini, Milano" }, { address: "Viale Italia, Milano" }, { address: "Via Rodi, Milano" }, ] }); });

• Dynamically creating controls in MFC (Collection question)

  - by ProgramWriter

  Hello all, I have some custom control inside of which i should create radiobuttons or checkboxes. The count of child controls is available only at runtime (it loads some file from which it gets this count). So i need to create variable number of controls. Which collection i should use for this purpose? Solution 1: simply use std::vector (or CArray) - not suitable because i want use MFC (CButton). Of course i can Attach() and later Detach() handle to window each time i need this window, but it will give big overhead. Solution 2: use std::vector or CArray or CList or... In this case i take care about making 'new' and appropriate 'delete' when control is unneeded. I am forgetful :) MFC handle map contains pointer to CButton and i can't use simple CArray, because it will move my objects each time when his size will grow. ... and the question is: Which collection i should use for containing variable count of MFC control classes?

• Equality and Assigment Operators

  - by Jeremy Smith

  I have a assembly compiled in VB.NET that contains two operators: Public Shared Operator =(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return quarterA.StartDate = quarterB.StartDate AndAlso quarterA.EndDate = quarterB.EndDate AndAlso quarterA.Quarter = quarterB.Quarter End Operator Public Shared Operator <>(quarterA As CalendarQuarter, quarterB As CalendarQuarter) As Boolean Return Not (quarterA = quarterB) End Operator However, when using the assembly in C# to perform equality checks if (qtr != null) I receive the error: Cannot implicity convert type 'object' to 'bool' My original intent with the = operator was only for assignment purposes in VB, so I may be way off base (I don't use custom operators too often). What do I need to do to make the operator behave with both equality and assignment operations?

• Wrangling Control of HTTP Headers in ASP.NET

  - by Andrew Burgess

  I'm working with ASP.NET MVC3, and I'm trying to get absolute control over my headers because a client application that I'm working with expects a very specific content type. What I'm finding when using Fiddler to examine the HTTP traffic is that the text encoding is being returned as part of the header. For example, the client is expecting application/appname in the Content-Type header, but the server is returning application/appname; charset=utf-8. I think the client is using a strict comparison for checking the type, so I want to be able to specify exactly what is emitted in the headers. Right now I have a custom ActionResult in which I clear the headers and then specify only the content type, but the encoding still seems to be added on. How can I remove the encoding from the Content-Type header?

• How do I create a class associated with a windows form in C#?

  - by xarzu

  Now that C++ development has become second nature to me, do I have to start from scratch with C#? Since the beginning of Visual Studio, there has been easy way to describe the shape of a Dialog (now called a Form) in the resource file and then use a wizard to create the corresponding C++ code. I kind of remember that in MFC it was pretty much a no-brainer to create a custom dialog with all the components you want and then all the associated code. If I have a C# app that has many forms that I want to bring to the screen based on the user's menu selections, how do I create a class associated with a windows form?

• Is my approach correct to replicate this form with Reportlab?

  - by Wes

  I need to generate the form seen here using Python/reportlab. http://www.flickr.com/photos/49740282@N06/4563137758/sizes/o/ I am attempting to do this by creating a custom flowable for the header at the top (with the boxes drawn) and then having a table flowable for the jewelry table below. What shows as the JEWELRY table for this example could potentially be multiple tables. I am having trouble getting my drawn header to "flow". It gets drawn, but then my table data overlays it instead of appearing below it. This is my first project with reportlab. Before I really get into debugging this, I would like to know from someone with reportlab experience if my approach is correct here. Thanks!

• Does the android market use your merchant API callback URL during the Google checkout process for pa

  - by tootflow

  If I have a paid app on Android Market, will my merchant API callback URL get a hit when the customer goes to check out? I am wondering how merchants/vendors/developers secure their applications for android market. I have used google checkout before to implement a custom integration, so I understand how that all works. What I do not see anywhere that I have looked is what, if any, integration does the merchant/developer have with the Android Market checkout process? I understand that the market uses google checkout, but in that case the market hosts the checkout process and not the merchant, so it's not clear whether they give your URL a call. So where is the hook? Am I right in assuming it is the merchant API callback URL?

• comparator with null values.

  - by pvgoddijn

  Hi, We have some code wich sorts a list of addresses based on the distance between their coordinates. this is done through collections.sort with a custom comparator. However from time to time an adress without coordinates is in the list causing a NullPointerException. My initial idea to fix this was to have the comparator return 0 as dististance for addresses where at least one of the coordinates is null. I fear this might lead to corruption of the order the 'valid' elements in the list. so is returning a '0' values for null data in a comparator ok, or is there a cleaner way to resolve this.

• Dialing a command prefix on the iPhone

  - by tewha

  Our application lets users call phone numbers. Users would like to be able to block their caller ID. On other platforms, we let the user specify a custom dialing prefix. For instance, on my cell provider it's #31#. I've tried two approaches so far. First: id url = [NSURL URLWithString: @"tel:#31#0000000"] // produces nil Second: id encoder = ["#31#0000000" stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]; // produces %2331%230000000 id url = [NSURL URLWithString: [NSString stringWithFormat: @"tel:%@", encoded]]; // produces a valid-looking NSURL which doesn't do anything I'm thinking at this point that I'm just not allowed to dial # and *, even from a Cocoa touch application. (I know it's not allowed from a web app.) Is this true, or am I missing something obvious?

• Which full-text search package should I use for SQLite3?

  - by Benjamin Pollack

  SQLite3 appears to come with three different full-text search engines, called FTS1, FTS2, and FTS3. The documentation available on the website mentions that FTS1 is stable, FTS2 is in development, and that you should use FTS2. Examples I find online use FTS3, which is in CVS, and not documented versus FTS2. None of the full-text search engines come with the amalgamated source, as near as I can tell. So, my question: which of these three engines, if any, should I use for full-text indexing in SQLite? Or should I simply use a third-party tool like Sphinx, or a custom solution in Lucene, instead?
