• Selectedindex in listview, throwing up an error!

  - by Luke

  Hey guys, the following code shows what i am trying to do. private void btnEdit_Click(object sender, EventArgs e) { iDeliverySelected = lstDeliveryDetails.SelectedIndex; bool addEdit = false; } The selectedindex is throwing up the following error.. 'System.Windows.Forms.ListView' does not contain a definition for 'SelectedIndex' and no extension method 'SelectedIndex' accepting a first argument of type 'System.Windows.Forms.ListView' could be found (are you missing a using directive or an assembly reference?) Any ideas why? First time I have tried to use SelectedIndex, not sure if i am using it correctly?

• Get the entire string of a jquery DOM object

  - by Scozzard

  Hi, I have had a bit of a look around and am having some difficulty solving a wee issue I am having. I basically have a string of HTML, I convert that to a JQuery DOM object so that I can easily remove all elements that have a certain class using JQuery's .remove(). I.e., var radHtml = editor.get_html(); var jqDom = $(radHtml); $(".thickbox", jqDom).remove(); editor.set_html(jqDom.html()); The only problem is that .html() only gets the first element, not the entire DOM. In reference to my code I am basically wanting radHhtml - elements with class "thickbox" (returned as string). I was wondering if there was an easy way to do this - have some html and remove all elements (in this case divs) that have a certain class (but leaving their contents). JQuery doesnt have to used, but I would like to. Any help would be much appreicated. Thanks.

• asp.net ajax progress counter

  - by xt_20

  Hi all, I have a small C# ASP.NET app, and want to include an Ajax progress counter. The architecture is currently like this: Web Application -- calls a class that does the upload For example, in default.aspx, I call : FileHelper fh = new FileHelper() fh.MoveFiles(file) I have an Ajax control that fires when the above is called. This is a control that resides on the website class/project. How do I update the progress counter from the Filehelper class? (I don't think calling the control directly would work as it would be a circular reference) Also how do I continuously update the counter? Thanks all

• Creating a C# webservice client having SoapParameterStyle as Bare as opposed to wrapped

  - by Pratik Bhatt

  I am trying to create a Soap Web Service Client using the Visual C# 2008 Express IDE. I Do that by Right-Clicking Project Name-Add service Reference. Everything is working out fine, and the client is being generated as follows [System.Web.Services.Protocols.SoapDocumentMethodAttribute("operationInfo", RequestElementName="mainInfoTag", RequestNamespace="http://www.example.com/test", ResponseElementName="Answer", ResponseNamespace="http://www.example.com/test", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] [return: System.Xml.Serialization.XmlElementAttribute("somenewID")] public string storeWarrantyInformation(tagBelowMainInfoTag tag, out string somenewID, out string someotherID) As you can see, the method is marked with SoapParameterStyle.Wrapped, what this is does is that it does not create a class corresponding "mainInfoTag". The Questions I have is what determines the Client SoapParameterStyle in the proxy class. I would like to get SoapParamterStyle as Bare, so that I have access to the root XML element. Is there some setting I can specify in the IDE or through 'wsdl.exe' to make this happen.

• Sql query: use where in or foreach?

  - by phenevo

  Hi, I'm using query, where the piece is: ...where code in ('va1','var2'...') I have about 50k of this codes. It was working when I has 30k codes, but know I get: The query processor ran out of internal resources and could not produce a query plan. This is a rare event and only expected for extremely complex queries or queries that reference a very large number of tables or partition I think that problem is related with IN... So now I'm planning use foreach(string code in codes) ...where code =code Is it good Idea ??

• Using type hints in Clojure for Java return values

  - by mikera

  I'm working on some Java / Clojure interoperability and came across a reflection warning for the following code: (defn load-image [resource-name] (javax.imageio.ImageIO/read (.getResource (class javax.imageio.ImageIO) resource-name))) => Reflection warning, clojure/repl.clj:37 - reference to field read can't be resolved. I'm surprised at this because getResource always returns a URL and I would therefore expect the compiler to use the appropriate static method in javax.imageio.ImageIO/read. The code works fine BTW so it is clearly finding the right method at run time. So two questions: Why is this returning a reflection warning? What type hint do I need to fix this?

• Referencing View directory in asp.net mvc

  - by ooo

  i have some html files as part of a regular website that has been ported over to asp.net mvc. In my code i need to read and write these html files and stick them in a tinymce editor To be able to read and write this file from disk in the past i had a hard coded path but this doesn't seem to work in asp.net mvc unless i do something like this: Writing: string _urlDirectory = @"c:\hosting\MySite\Views\Members\newsletters\test.html"; System.IO.File.WriteAllText(_urlDirectory, htmlData_); Reading: string url = @"c:\hosting\MySite\Views\Members\newsletters\test.html"; var req = WebRequest.Create(url); var response = req.GetResponse(); StreamReader sr = new StreamReader(response.GetResponseStream()); string htmlData_ = sr.ReadToEnd(); i am moving my site from one data center to another and the directory structure is changing. instead of just changing the hard coded path to another hard coded path i wanted to see if there was a more relative way to reference these files.

• How do you move the pointer up or down multiple lines with Emacs?

  - by Peter

  I can move my pointer up and down one line with my arrow key just fine in Emacs, so I'd like to redefine C-n and C-p to move up and down 5 lines at a time. I'm just beginning to learn how to use Emacs, and elisp is very alien to me. I tried using the GNU Emacs lisp reference, but I couldn't find how to bind a keystroke to multiple commands. Here's what I have so far (concentrating on the moving up definition): (global-set-key "\C-p" '(loop for i in '(1 2 3 4 5) do ('previous-line))) But, this brings up an error message when I hit C-p, "Wrong type argument." Any suggestions? Thanks!

• Ignoring generated files when using "Treat warnings as errors"

  - by krystan honour

  We have started a new project but also have this problem for an existing project. The problem is that when we compile with a warning level of 4 we also want to switch on 'Treat all warnings as errors' We are unable to do this at the moment because generated files (in particular reference.cs files) are missing things like XML comments and this generates a warning, we do not want to suppress the xml comment warnings totally out of all files just for specific types of files (namely generated code). I have thought of a way this could be achieved but am not sure if these are the best way to do this or indeed where to start :) My thinking is that we need to do something with T4 templates for the code that is generated such that it does fill in XML documentation for generated code. Does anyone have any ideas, currently I'm at well over 2k warnings (its a big project) :(

• signed angle between two 3d vectors with same origin within the same plane? recipe?

  - by Advanced Customer

  Was looking through the web for an answer but it seems like there is no clear recipe for it. What I need is a signed angle of rotation between two vectors Va and Vb lying within the same 3D plane and having the same origin knowing that: the plane contatining both vectors is an arbitrary and is not parallel to XY or any other of cardinal planes Vn - is a plane normal both vectors along with the normal have the same origin O = { 0, 0, 0 } Va - is a reference for measuring the left handed rotation at Vn The angle should be measured in such a way so if the plane would be XY plane the Va would stand for X axis unit vector of it. I guess I should perform a kind of coordinate space transformation by using the Va as the X-axis and the cross product of Vb and Vn as the Y-axis and then just using some 2d method like with atan2() or something. Any ideas? Formulas?

• iphone: Accessing Code for Elements Created in Interface Builder

  - by user362685

  I am attempting to create a basic tab-bar application using interface builder. I create a new project in Xcode selecting tab bar application. My question is how can I access the code that instantiates and pushes each of the views when the tab bar buttons are pressed? I would imagine that would be done by the tab bar controller, however when I write the class file from interface builder (filewrite class files), it just creates a blank generic TabBarController.h/TabBarController.m without the methods for pushing each of the views associated with the tab bar elements. I ask this because I would like to pass each view controller a reference to the data model when they are instantiated. Any help would be greatly appreciated, thanks.

• Dynamic domain methods missing from grails service when injected into java service in grails app.

  - by Gordon C

  I had the idea that I would write my GroovyDao as a grails service. Next I would write a MyJavaService in java and locate it in the java sources dir in my grails app. MyJavaService contains a instance reference to groovyDao for spring injection. I would wire up in resources.groovy the MyJavaService with a groovyDao = ref("GroovyDao"). Everything starts up fine. However if I make call to MyJavaService any Domain method like Domain.list() returns a Method not found error. Any help is appreciated.

• Concise description of the lua vm?

  - by anon

  I've skimmed Programing in Lua, I've looked at the Lua Reference. However, they both tells me this function does this, but not how. When reading SICP, I got this feeling of: "ah, here's the computational model underlying scheme"; I'm trying to get the same sense concerning lua -- i.e. a concise description of it's vm, a "how" rather than a "what". Does anyone know of a good document (besides the C source) describing this? Thanks!

• Overloading operator>> for case insensitive string

  - by TheSOFan

  Given the definition of ci_string from cpp.reference.com, how would we go about implementing operator? My attempts at it involved std::read, but it doesn't seem to work (that is, gcount() properly counts the number of characters entered, but there is no output) #include <iostream> #include <cctype> #include <string> // ci_string definition goes here std::istream& operator>>(std::istream& in, ci_string& str) { return in.read(&*str.begin(), 4); } int main() { ci_string test_str; std::cin >> test_str; std::cout << test_str; return 0; }

• Advice about a good Java book?

  - by camac1

  Hi people, I am new to Java but have experience programming in C/C++/C#. I wanted to learn Java SE 6 first before moving to Java EE 6. After making some research online for appropriate Java SE 6 books, I found that these are appropriate for me to get an excellent idea of Java SE 6: 1) Head First Java, 2nd Edition 2) An Intermediate Level Book <----------- 3) Effective Java (2nd Edition) 4) Java Concurrency in Practice 5) Java Generics and Collections 6) Java Concise Reference Series: Swing And AWT 7) Java Reflection in Action However, I am having trouble choosing an Intermediate Level Book which will provide me with breadth and depth in Java SE 6. I was thinking about the book "Thinking in Java (4th Edition)"....Unfortunately, its deals with Java SE 5 and not the latest version. Could anybody please advice me an intermediate level book which could provide me with breadth and depth in Java SE 6. Regards

• Classic ASP and MVC side-by-side, different projects?

  - by David Lively

  I've tried asking this in a few different ways, but let's give it another shot (as I've yet to receive an answer and this is driving me nuts!) I have a very large classic ASP 3.0 application (~350K lines) that I want to start migrating to ASP.NET MVC. I'd like to keep the old ASP files in a separate project from the MVC stuff. Ideas on how to debug these? Should I just dump the files in the same folder and create two different projects ( a WAP and an MVC app) that reference the relevant files and folders required by each? This should work, but does anyone have a better idea? I need the ability to migrate small parts of the application individually as this will probably take a year or two to complete.

• Why is there no .NET Community Process?

  - by michielvoo

  I was doing some research into general topics of software engineering and I came across the Java Community Process website: The JCP is the mechanism for developing standard technical specifications for Java technology. Anyone can register for the site and participate in reviewing and providing feedback for the Java Specification Requests (JSRs), and anyone can sign up to become a JCP Member and then participate on the Expert Group of a JSR or even submit their own JSR Proposal. Seems like a good idea to me, and there are lots of very well written specifications and reference implementations on the JCP website. So why is there no .NET Community Process? Is that something that Microsoft could or should start? Maybe they could install it on Codeplex.net and hand over the keys to the community.

• PropertyInfo SetValue and nulls

  - by Nelson

  If I have something like: object value = null; Foo foo = new Foo(); PropertyInfo property = Foo.GetProperties().Single(p => p.Name == "IntProperty"); property.SetValue(foo, value, null); Then foo.IntProperty gets set to 0, even though value = null. It appears it's doing somemething like IntProperty = default(typeof(int)). I would like to throw an InvalidCastException if IntProperty is not a "nullable" type (Nullable< or reference). I'm using Reflection, so I don't know the type ahead of time. How would I go about doing this?

• How do I retrieve readonly values when using a DetailsView control to update a record?

  - by lincolnk

  I'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection. I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?

• C# Code Smells. What are the most common and how to fix them?

  - by Carlos Loth

  Hi, One thing I'd like to hear from you guys is what are the code smells that you see most often happen on C# code and how to fix them. I'm working on defining a code-review process for my team and I'd like to include a section with the most common C# code smells and a possible fix for each of them. I'd like the assistance of the community on that, so others can reuse this list for further reference. What are the most common smells you have seen on C# code? How did you fix them?

• ASP.NET JavaScript File Embeded In DLL With GZIP

  - by Lee Hesselden

  We have several fairly large JavaScript files embedded into a single script resources DLL. This is then consumed by multiple projects by way of a reference and page includes via the ASP.NET script manager. This keeps things nice and neat within our ASP.NET pages and requires very little work to integrate into new projects. The problem is that some of these script files are quite larger (approx 100KB) and take time to download. By running minify on them before embedding this is reduced down a lot (around 70KB) but not enough. What we would like to do is GZIP the files before they are embedded. However, just gzipping the files causes syntax errors as the content is not unzipped. There is a content type "text/javascript" applied in AssemblyInfo when the resource is embedded but we can't find a way to specify content-encoding. Is there any way to make this work without having to write a httpmodule/handler (which would mean changing the config for all consuming projects)?

• How do I copy an object in Java?

  - by Veera

  Consider the below code: DummyBean dum = new DummyBean(); dum.setDummy("foo"); System.out.println(dum.getDummy()); // prints 'foo' DummyBean dumtwo = dum; System.out.println(dumtwo.getDummy()); // prints 'foo' dum.setDummy("bar"); System.out.println(dumtwo.getDummy()); // prints 'bar' but it should print 'foo' So, I want to copy the 'dum' to dumtwo' and I want to change 'dum' without affecting the 'dumtwo'. But the above code is not doing that. When I change something in 'dum', the same change is happening in 'dumtwo' also. I guess, when I say dumtwo = dum, Java copies the reference only. So, is there any way to create a fresh copy of 'dum' and assign it to 'dumtwo' ?
