• ListView not importing data

  - by ct2k7

  Hello, I'm trying to import data into a listview and this is the code I'm using: Private Sub form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim doc As New XmlDocument doc.Load("http://user:[email protected]/1/statuses/mentions.rss") Dim nodes As XmlNodeList = doc.SelectNodes("Statuses/Status") For Each node As XmlNode In nodes Dim text As String = node.SelectSingleNode("text").InnerText Dim time As String = node.SelectSingleNode("created_at").InnerText Dim screen_name As String = node.SelectSingleNode("user/screen_name").InnerText ListView1.Items.Add(New ListViewItem(New String() {screen_name, text, time})) Next End Sub Any ideas what's going wrong here?

• JSP load external php not using iFrames

  - by Rudiger

  I have a bit of an issue with a site I maintain. I have been asked to add a report to a page that sits in a jsp page. The reporting information comes from a MySQL database. The problem is to connect the jsp to the database would require added functions to code that I do not have the original source of. I thought about redoing all the db connection again but thats a lot of time for something that will probably be rewritten in 3 weeks. Then I thought of just using PHP to display the report in the jsp as I have other pages connecting to the database using php (long story as to why were are using 2 languages). But the only way I know of is by using iFrames which is a bit of a no no. Using the object tag I've seen also has errors in IE. What would be the best way to do this?

• How does Unity.Resolve know which constructor to use?

  - by stiank81

  Given a class with several constructors - how can I tell Resolve which constructor to use? Consider the following example class: public class Foo { public Foo() { } public Foo(IBar bar) { Bar = bar; } public Foo(string name, IBar bar) { Bar = bar; Name = name; } public IBar Bar { get; set; } public string Name { get; set; } } If I want to create an object of type Foo using Resolve how will Resolve know which constructor to use? And how can I tell it to use the right one? Let's say I have a container with an IBar registered - will it understand that it should favor the constructor taking IBar? And if I specify a string too - will it use the (string, IBar) constructor? Foo foo = unityContainer.Resolve<Foo>(); And please ignore the fact that it would probably be easier if the class just had a single constructor...

• choose a tool to create/maintain custom eclipse distrib

  - by raticulin

  I would like to settle on a tool to create/maintain my custom eclipse distrib (starting with next 3.6). By studying previous questions main contenders seem: Pulse Yoxos doing it yourself in eclipse Has anyone experiences in several of them and can comment on advantages etc?? My wishes are: by 'distrib' I mean: plugins, settings & preferences... be able to use the same eclipse setup in several workstations MAYBE sharing with other members of the team works across 3.5 and next 3.6: I don't know if it's possible. And anyway I would not object to customize the distrib once per new eclipse major release

• Weak linking on iPhone refuses to work

  - by Jonathan Grynspan

  I've got an iPhone app that's mainly targetting 3.0, but which takes advantage of newer APIs when they're available. Code goes something like this: if (UIApplicationDidEnterBackgroundNotification != NULL) [nc addObserver: self selector: @selector(irrelelvantCallbackName:) name: UIApplicationDidEnterBackgroundNotification object: nil]; Now, according to everything Apple's ever said, if the relevant APIs are weakly linked, that will work fine because the dynamic linker will evaluate UIApplicationDidEnterBackgroundNotification to NULL. Except that it doesn't. The application compiles, but as soon as it hits "if (UIApplicationDidEnterBackgroundNotification != NULL)" it crashes with EXC_BAD_ACCESS. Is this simply a matter of a compiler flag I need to set? Or am I going about this the wrong way?

• missing event when using modules with requirejs

  - by ali haider

  I had javascript code in a single JS file that was working fine (using XHR/AJAX). When I split it up into separate modules in a requirejs application, I do not seem to get a handle on the event object & it shows up as undefined (testing in firefox 29.0.1). Calling module: ajax.onreadystatechange = new ajaxResponse().handleAjaxResponse(e); ajaxResponse define(["require", './url/urlCommon'], function(require, urlCommon) { 'use strict'; var ajaxResponse = function() { var ajax = null; // e = event || window.event; this.handleAjaxResponse = function() { if (typeof event === 'undefined') { var event = event || window.event; } console.log('e is now:' + typeof e); I also do not have a handle on the event in the handleAjaxResponse method (error: undefined). Any thoughts on what I need to do to troubleshoot/fix this will be greatly appreciated.

• PHP - ADO recordsets

  - by Josh

  I am referencing a COM component from PHP. This COM component returns records using ADO. I am assuming I will need to reference ADO in PHP for this to function. How do I do this? Secondly (related to the first question) I have run accross ADODB abstraction libraries, however these seem to mostly deal with queries and handle the ADO internally. How do I get the returned ADO recordset into a PHP friendly array, and likewise pass in an ADO array to the COM object? Thank you, Josh

• [WPF C#]Get UserControl or VisualTree in DataValidation of TextBlock

  - by dalind

  Hy, I have a validator set on the text property of a textblock. For a correct validation I would need the parent usercontrol of the textblock, but the only things I have in the validator are the value object (a string) and the culture (doesn't help either). Does anyone know a way to get certain usercontrols in a class/a method where I have no access to any kind of visual or control of my application. The problem could be solve if I could give the validator the usercontrol or the textblock as parameters, but I didn't find a way to do so.. Thank you very much for your answers. Greets

• Is there a JSON parser for VB6 / VBA?

  - by Ben McCormack

  I'm trying to consume a web service in VB6. The service (which I control) currently can return a SOAP/XML message or JSON. I'm having a really difficult time figuring out if VB6's SOAP type (version 1) can handle a returned object (as opposed to simple types like string, int, etc.). So far I can't figure out what I need to do to get VB6 to play with returned objects. So I thought I might serialize the response in the web service as a JSON string. Does a JSON parser exist for VB6?

• Ruby IRB - Requires and Scope

  - by tyndall

  Trying to understand this problem I'm running into. I create file welcome.rb. The contents of this file: welcome_message = "hi there" I then launch an irb session. And type require 'welcome'. That works fine. Then I type: puts welcome_message I get the error message undefined local variable or method `welcome_message' for main:Object What is the best way to bring in predefined variables and have initialization work done when you require something into your irb session. Global variables didn't seem like the right path.

• SQL Server 2000 incorrect message: duplicate key with unique index

  - by iar

  Database server: SQL Server 2000 - 8.00.760 - SP3 - Standard Edition I have a table with 5 columns, in which I want to add a large (300.000) number of records. There is a unique index on the combination of two columns. If I add the records with this unique index in place, SQL Server gives this error message: Msg 2601, Level 14, State 3, Line 1 Cannot insert duplicate key row in object 'TESTTABLE' with unique index 'test'. The statement has been terminated. (0 row(s) affected) However, if I delete the unique index and then add the records, I do not get any error when I create this unique index afterwards.

• How to remove objects from an Enumerable collection in a loop

  - by johnc

  Duplicate Modifying A Collection While Iterating Through It Has anyone a nice pattern to allow me to get around the inability to remove objects while I loop through an enumerable collection (eg, an IList or KeyValuePairs in a dictionary) For example, the following fails, as it modifies the List being enumerated over during the foreach foreach (MyObject myObject in MyListOfMyObjects) { if (condition) MyListOfMyObjects.Remove(myObject); } In the past I have used two methods. I have replaced the foreach with a reversed for loop (so as not to change the any indexes I am looping over if I remove an object). I have also tried storing a new collection of objects to remove within to loop, then looping through that collection and removed the objects from the original collection. These work fine, but neither feels nice, and I was wondering if anyone has come up with a more elegant solution to the issue

• Nullable Date column merge problem

  I am using JPA with openjpa implementation beneath, on a Geronimo application server. I am also using MySQL database. I have a problem with updating object with nullable Date property. When I'm trying to merge entity with Date property set to null, no sql update script is generated (or when other fields are modified, sql update script is generated, but date field is ommited from it). If date field is set to some other not null value, update script is properly generated. Did anyone have problem like that?

• COMPLETE list of HTML tag attributes which have a URL value?

  - by system PAUSE

  Besides the following, are there any HTML tag attributes that have a URL as their value? href attribute on tags: <link>, <a>, <area> src attribute on tags: <img>, <iframe>, <frame>, <embed>, <script>, <input> action attribute on tags: <form> data attribute on tags: <object> Looking for tags in wide usage, including non-standard tags and old browsers as well as HTML 4.01, HTML 5, and XHTML. Yes this question is kinda lightweight, but I googled around for about 45 minutes and didn't find this data centralized anywhere, so I figure it might help some other developer to have it here. Plus I'm sure I'm missing something. Feel free to repeat/reorganize this list in your answer. Upvoting the most complete answers will probably be most helpful to others.

• Objective C: Create arrays from first array based on value

  - by Nic Hubbard

  I have an array of strings that are comma separated such as: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA Bill Gates,44,WA Bill Nye,21,OR I have those values in an NSScanner object so that I can loop through the values and get each comma seperated value using objectAtIndex. So, what I would like to do, is group the array items into new arrays, based on a value, in this case, State. So, from those, I need to loop through, checking which state they are in, and push those into a new array, one array per state. CA Array: Steve Jobs,12,CA Fake Name,21,CA Test Name,22,CA WA Array: Bill Gates,44,WA OR Array: Bill Nye,21,OR So in the end, I would have 3 new arrays, one for each state. Also, if there were additional states used in the first array, those should have new arrays created also. Any help would be appreciated!

• How to parse AMF data in Ruby?

  - by Matchu

  So I see that there are a few Rails plugins for serving AMF. However, is there a library that I can use in a Ruby environment to act as an AMF client: to read AMF data, and deserialize it into a Ruby object? If not, how could I best go about using tools built in other languages? I suppose I could write something in Python or Java or whatever, and call it from Ruby directly via backticks... but I'd first like to ensure that there isn't really any better option. Thanks!

• Boost.Python tutorial in Ubuntu 10.04

  I downloaded the latest version of Boost and I'm trying to get the Boost.python tutorial up and running on Ubuntu 10.04: http://www.boost.org/doc/libs/1_43_0/libs/python/doc/tutorial/doc/html/python/hello.html I navigated to the correct directory, ran "bjam" and it compiled using default settings. I did not yet create a bjam config file. The compilation appears to have worked, but now I have no idea how to include the files in my python script. When I try to run the python hello world script, it gives me this error: Traceback (most recent call last): File "./hello.py", line 6, in <module> import hello_ext ImportError: libboost_python.so.1.43.0: cannot open shared object file: No such file or directory Anyone know what is going on?

• access denied trying extracting an archive on the windows user temp folder

  - by Hanan

  I'm trying to run a command-line process (which is extraction of a .7z archive) on a file that lies in a temporary folder on the windows user temp directory (C:\Documents and Settings\User\Local Settings\Temp), using Process in my c# app. I think the process return error that happens because of "access denied" because I can see a win32Exception with error code 5 when I dig in the prcoess object of .NET. doing the same on some other location worked fine before, so I guess maybe it's something I'm not supposed to do ? (running a process to use a file on the the %TEMP%) perhaps I need to pass security somehow?

• jQuery event handlers always execute in order they were bound - any way around this?

  - by asgeo1

  It can be anoying that jQuery event handlers always execute in the order they were bound. For example: $('span').click(doStuff1()); $('span').click(doStuff2()); clicking on the span will cause doStuff1() to fire, followed by doStuff2(). At the time I bind doStuff2(), I would like the option to bind it before doStuff1(), but there doesn't appear to be any easy way to do this. I suppose most people would say, just write the code like this: $('span').click(function (){ doStuff2(); doStuff1(); }); But this is just a simple example - in practise it is not always convienient to do that. There are situations when you want to bind an event, and the object you are binding to already has events. And in this case you may simply want the new event to fire before any other existing events. So what is the best way to achieve this in jQuery?

• Unit Testing XML independent of physical XML file

  - by RAbraham

  Hi, My question is: In JUnit, How do I setup xml data for my System Under Test(SUT) without making the SUT read from an XML file physically stored on the file system Background: I am given a XML file which contains rules for creation of an invoice. My job is to convert these rules from XMl to Java Objects e.g. If there is a tag as below in my XML file which indicates that after a period of 30 days, the transaction cannot be invoiced <ExpirationDay>30</ExpirationDay> this converts to a Java class , say ExpirationDateInvoicingRule I have a class InvoiceConfiguration which should take the XML file and create the *InvoicingRule objects. I am thinking of using StAX to parse the XML document within InvoiceConfiguration Problem: I want to unit test InvoiceConfiguration. But I dont want InvoiceConfiguration to read from an xml file physically on the file system . I want my unit test to be independent of any physical stored xml file. I want to create a xml representation in memory. But a StAX parser only takes FileReader( or I can play with the File Object)
