  • Visual Studio 2005 - strange characters rendered for ANSI text

    - by Apogee
    Hi all, Has anyone seen this odd text rendering issue in VS2005 before? The first line of using statements actually says "using System;". If I copy the line as it is displayed and paste into notepad, the text appears correctly, so clearly the character codes are correct. In addition, the solution compiles and runs correctly. I was thinking it might be due to ClearCase using a different character encoding as all the solutions we're using were freshly checked-out yesterday on to a new build machine, but this is only happening in 2 of our ~30 solutions. Incidentally the same .cs files when opened in VS2008 render correctly on this machine, could this be a corruption in VS2005?

  • understanding syb boilerplate elimination

    - by Pradeep
    In the example given in http://web.archive.org/web/20080622204226/http://www.cs.vu.nl/boilerplate/ -- Increase salary by percentage increase :: Float -> Company -> Company increase k = everywhere (mkT (incS k)) -- "interesting" code for increase incS :: Float -> Salary -> Salary incS k (S s) = S (s * (1+k)) how come increase function compiles without binding anything for the first Company mentioned in its type signature. Is it something like assigning to a partial function? Why is it done like that?

  • What programming languages do you consider indispensable in your experience?

    - by Federico Ramponi
    Each programming language comes with its concepts, best practices, libraries, tools, community, in one word: culture. Learning more than one programming language will make you a better programmer, for the more concepts you learn, the faster you will feel comfortable when the next language or technology will come. Mine, so far, are C, some C++, and Python, and many times I read that it would be worth learning LISP, for "the profound enlightenment experience you will have when you finally get it" (quoting Eric Raymond). My questions are: Which is the next one you would consider a good investment to learn? Of the many programming languages you have learnt and worked with, which ones do you consider to be an essential part of one's CS culture, and why? EDIT. Further question: is there any language you would sincerely advise to avoid as a waste of time? (The famous, and questionable, slatings in this letter from Dijkstra come to my mind.)

  • Debug.Assert seems not to work in Mono

    - by Jan-Willem
    Consider the following C# program: using System; using System.Diagnostics; namespace Test { class MainClass { public static void Main (string[] args) { Debug.Assert(false); Debug.Fail("fail!"); Console.WriteLine ("Hello World!"); } } } When compiling this using: dmcs -debug -d:DEBUG Main.cs and then running it with: mono --debug Main.exe the assertion and fail seem to be ignored. The output is just: Hello World! I checked other related questions on StackOverflow, but I could not find a solution. In particular the solution give in Mono - Debug.Assert does not work does not work. (UPDATE: the update solution does work, see below comments.) I use Mono 2.1.5-1 on Ubuntu 11.10.

  • Problem loading RTF file into windows richTextBox

    - by Ted
    I am trying to load files into a windows (vs 2010) richTextBox but only the first line of the file is loading. I'm using: // Create an OpenFileDialog to request a file to open.

  • C#: How to kill a singleton window

    - by Anonymous Coward
    Hi Everyone I'm working on a WPF application which should be utilizable with two monitors. In the main window is a button which detaches a part of the content in a second window wich can then be used on the other minitor. That second window I implemented as a singleton. That works quite good except that the second window doesn't get destoryed on application shutdown which means that the app keeps running in the background. Regarding that problem I'd like to know if a singleton is the right way to do this and if not what would be the right way. If it is, how do I get rid of the instance and why can't I access the singleton instance from app.xaml.cs? Thanks for your help.

  • VS 2010 Error “Object reference not set to an instance of an object” when adding Service Reference f

    - by Andy
    I have a VS2010 (RTM) solution which contains: WCF Service project Console WCF client project Class project for DataContracts and members Class project for some simple classes I successfully added a service reference in the console client project and ran the client. I then did a long dev cycle repeatedly modifying the service then updating console service reference. I then changed the namespace and assembly names for the projects as well as the .cs using references and app.config. I of course missed some things as it would not build so I eventually removed the project references and the service reference, cleaned and built successfully. I then attempted to add the service reference again, it discovered it but threw the “Object reference not set to an instance of an object” when OK'ing. Fix in answer below...

  • The underlying connection was closed when using a WSDL web service

    - by joshlrogers
    I am trying to consume this WSDL service: Transit Time Service I successfully connect and get a response the first time but on subsequent calls I receive the exception: The underlying connection was closed: A connection that was expected to be kept alive was closed by the server. I overrode the GetWebRequest in the reference.cs file as such: protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest webRequest = (HttpWebRequest)base.GetWebRequest(uri); webRequest.KeepAlive = false; return webRequest; } This hasn't yielded any improvement. I am at a loss as to what options I have now, does anyone have any other ideas that I could try so that I may avoid this error? Thanks in advance! Josh

  • Dropdown binding and postbacks - ASP.NET

    - by DotnetDude
    I have a rather complex page. The ASPX page loads a user control which in turn loads a child User control. Parent Control protected override void OnInit(EventArgs e) { //Loads child control } In the child user control, I use custom control that inherits from System.Web.UI.HtmlControls.HtmlSelect ASCX: <cust:CustDropDownList id="ctlDdl" runat="server"/> ASCX.CS protected void Page_Load(object sender, EventArgs e) { //Binds CtlDdl here } When the user clicks on the Save button, the controls get user controls get dynamically reloaded, but Iose the value the user has selected in the dropdown. I run into the chicken and egg problem here. I think I need to bind the ctlDdl only on if its not a postback, but that results in the dropdown not getting populated. If I bind it everytime, then i lose user's selection EDIT: Can someone respond to my comment to Jonathan's answer? Thanks

  • C# (ASP.Net) Linking selection values to constants in Codebehind

    - by jasonvogel
    ASPX Code <asp:RadioButtonList ID="rbServer" runat="server" > <asp:ListItem Value=<%=ServerDeveloper%>> Developer </asp:ListItemv <asp:ListItem Value="dev.ahsvendor.com"> dev.test.com</asp:ListItem> <asp:ListItem Value="staging.ahsvendor.com"> staging.test.com</asp:ListItem> </asp:RadioButtonList> ASPX.CS - Codebehind const string ServerDeveloper = "developer"; ASPX Error: Code blocks are not supported in this context. Question: So what is the correct way to tie an dropdown/radio buttion/... ASPX value to a constant that is shared with the CodeBehind code? I know that I could do rbServer.Add.Item("developer") [from the CodeBehind], but is there a way to achieve it from the Presentation side of things?

  • Looking for a source code management system with a good GUI client

    - by Anders Öhrt
    We are currently using CS-RCS Pro for source code management, and are looking for to replace this due to performance issues. It is based on client side file access with no own protocol, which makes it painfully slow to use over a slow VPN line since it always rewrites the whole history of a file. It does however have a GUI client which is very simple and gives a great overview. We have three main requirements in a SCM: Fast. It must have a server side service or some other smart way so working with files with a large history is fast. A good Windows GUI client (not Explorer shell integration, not VS or Eclipse IDE integration), so working with files and branches is easy. The possibility to have several branches checked out at once in different directories. Does anyone have a recommendation of a SCM which fulfills there requirements?

  • How do I save an altered image in matlab?

    - by ef-i-blinky
    So I am using the code located here: http://wwwx.cs.unc.edu/~sjguy/CompVis/Features/BlobDetect.m and I was wondering how to save the final blob detected image. The image that I am doing the blob detection on gets shown and then he manually draws the lines on the image here: Xbar = cx1+X.*cos(alpha)+Y.*sin(alpha); Ybar = cy1+Y.*cos(alpha)-X.*sin(alpha); line(Xbar', Ybar', 'Color', color, 'LineWidth', ln_wid); I then want to save this image using something like imwrite. I have been reading around and it seems that no one really has an answer to to this problem. Thanks for any help you can give me, Josh

  • Redirect to prevent dup submission...but then you loose existing data

    - by coffeeaddict
    Here's the scenario User is on your checkout.aspx page Somewhere in the process, when clicking the pay button, you redirect the user to an intermediate page (before the confirmation page) to do some other logic. That intermediate page performs whatever logic based on a querystring flag you sent with the redirect from the checkout page This intermediate page also serves as an error page. So if any logic in the intermediatePage.aspx.cs fails I'm setting a message to be displayed on this page to the user If I refresh, that querystring value is still in the url..hence when it hits my Page_Load again, then the server-side logic is called & run again and I don't want this to happen The avoid this behavior/problem, the logical next step is to do a redirect back to the same page if they refresh (not sure how you'd catch that) to get rid of that querystring But when you redirect back to the same page your error message is gone, lost in the redirect therefore you end up showing them the same page but all values for the error message are now gone I do not want to solve this with Javascript either. I am not sure the best way to handle this.

  • Dynamically add rows to listbox

    - by Ivan S
    I have a list box that displays information off of a column of a dataset. I would like the number of rows displayed to be all the rows that are in the dataset (the number of datasets in the rows vary). I'm figuring it has something to do with ListBox.Rows = Dataset.Tables[0].Rows.Count; But it seems to just always default to 4 even when it is only 2. This is what I have in my aspx.cs file. pirateBox.DataTextField = Pirateship.Tables[0].Columns["displayName"].ToString(); pirateBox.DataValueField = pirateship.Tables[0].Columns["PKID"].ToString(); pirateBox.DataSource = pirateship.Tables[0]; pirateBox.DataBind(); pirateBox.Rows = pirateship.Tables[0].Rows.Count; I've been trying a few things and this is what I have so far in .aspx <asp:ListBox ID="pirateBox" runat="server" Rows="1"></asp:ListBox>

  • How to write back to database from Silverlight?

    - by Manoj
    Hi, I use LINQ to SQL to get data from a database and use a service contract to access it in Silverlight at the client side. I display the data in a DataGrid. Now how do I make sure that any changes in the datagrid is written back to the database? EDIT: This is the example code I implemented: http://www.silverlight.net/learn/tutorials/sqldatagrid-cs/ Here I wanted any change in the datagrid reflected back in the database. The SubmitChanges function works in the DataContext object which is: public partial class DataClasses1DataContext : System.Data.Linq.DataContext But this is not exposed in the contract and so not visible in the client side code.

  • IIS7 and ARR as reverse proxy for Subversion

    - by Paul Stovell
    I am using IIS7 and the Application Request Routing extension to act as a reverse proxy to Subversion running on Apache. The proxy works fine and I am able to explore the server, and even perform a "check out". However, I cannot browse to files that would normally be forbidden by ASP.NET - for example, .cs, .csproj, and so on. Files ASP.NET wouldn't be concerned with - such as .txt - are fine. I tried to edit the global web.config to remove the Forbidden handler mapping for these files, but it did not seem to make a difference. Is there any way to allow the URL rewriting module in IIS7 to work, while allowing all file extensions to be rendered?

  • Visual Studio 2010 Not Recognizing Unit Test

    - by jmease
    In an existing solution I added a new Test Project. In my Test Project .cs file I have a class decorated with the [TestClass] attribute and a method decorated with the [TestMethod] attribute. I have verified that in Configuration Manager the build check box is checked for the Test Project (as my google search has revealed was the problem for others with this issue). I have set Test Project as my start up project for the solution. When I try to start the test I get "Can not start test project because the project does not contain any tests". I am really new to unit testing. What am I missing?

  • When using source control, what files should actually be commited?

    - by SimpleCoder
    I am working on a small project, hosted on Google Code, using SVN for source control. This is my first time using source control, and I'm a bit confused about what I should actually be committing to the repository. My project is very simple: A Class Library project, written in C#. The actual code that I have written is a single file. My question is this: Should I be committing the entire project (including directories like Debug, Release, Properties, etc.) or just my main .cs file? Thanks, After fighting with Subversion for a while (note to self: do not reset repository), it looks like I finally have it working with the directories laid out properly. Thanks again for all your advice.
