  • XNA/C# Game Settings (Menu?)

    - by PCAddict
    It's my first time trying to make anything really interesting in C# and I was trying to make a simple form or game screen where the user could define a custom resolution/screen ratio etc. or to automatically detect the max screen size/ratio and output? its my first game, so I was wondering if it was possible or if there would be any major issues with such, rather than just setting it to 1366x768 (the resolution of all of my computers). Thanks in advance for any assistance.

  • How to make a floating (tooltip) control in Windows.Forms?

    - by Daren Thomas
    The Scene: A (smallish) Form hosting a UserControl. The Plot: Whenever UserControl raises a hover event, display some (graphical) information in a tool tip fashion. When the user moves the mouse, fade them away again. Notes: I'd like to display more than one "tooltip", with each tooltip being a UserControl displaying information in a graphical manner. Not just text in a yellow box! Also, I'm using the Windows.Forms library.

  • WebBrowser question

    - by James Jeffery
    I have a web page loaded into a WebBrowser object. What I want to do is access the elements on that page to input data. For example, enter username and password and submit the form. How is this possible? Any ideas? Could I use HTMLAgilityPack to access the elements and set their values?

  • how to implement a "soft barrier" in multithreaded c++

    - by Jason
    I have some multithreaded c++ code with the following structure: do_thread_specific_work(); update_shared_variables(); //checkpoint A do_thread_specific_work_not_modifying_shared_variables(); //checkpoint B do_thread_specific_work_requiring_all_threads_have_updated_shared_variables(); What follows checkpoint B is work that could have started if all threads have reached only checkpoint A, hence my notion of a "soft barrier". Typically multithreading libraries only provide "hard barriers" in which all threads must reach some point before any can continue. Obviously a hard barrier could be used at checkpoint B. Using a soft barrier can lead to better execution time, especially since the work between checkpoints A and B may not be load-balanced between the threads (i.e. 1 slow thread who has reached checkpoint A but not B could be causing all the others to wait at the barrier just before checkpoint B). I've tried using atomics to synchronize things and I know with 100% certainty that is it NOT guaranteed to work. For example using openmp syntax, before the parallel section start with: shared_thread_counter = num_threads; //known at compile time #pragma omp flush Then at checkpoint A: #pragma omp atomic shared_thread_counter--; Then at checkpoint B (using polling): #pragma omp flush while (shared_thread_counter > 0) { usleep(1); //can be removed, but better to limit memory bandwidth #pragma omp flush } I've designed some experiments in which I use an atomic to indicate that some operation before it is finished. The experiment would work with 2 threads most of the time but consistently fail when I have lots of threads (like 20 or 30). I suspect this is because of the caching structure of modern CPUs. Even if one thread updates some other value before doing the atomic decrement, it is not guaranteed to be read by another thread in that order. Consider the case when the other value is a cache miss and the atomic decrement is a cache hit. So back to my question, how to CORRECTLY implement this "soft barrier"? Is there any built-in feature that guarantees such functionality? I'd prefer openmp but I'm familiar with most of the other common multithreading libraries. As a workaround right now, I'm using a hard barrier at checkpoint B and I've restructured my code to make the work between checkpoint A and B automatically load-balancing between the threads (which has been rather difficult at times). Thanks for any advice/insight :)

  • Subsonic how do I filter a loaded collection?

    - by Kamikaze
    Currently I am using Subsonic 2.1 and .NET 2.1 and I have an issue where I am attempting to filter a pre-loaded collection with 300+ items. I am using the following to attempt to preform the filter: orders = MasterOrders.Where("account", mbrAccount).Load(); The end results is setting orders equal to the entire MasterOrders collection and not the filtered results. Any suggestions?

  • Table View Controller Problems

    - by happyCoding25
    Hello, I added a table view into a view in interface builder and now I need to wire it up to some pre-made classes that you can generate in xcode. I set the tableview controller's class to the class in xcode and wired the dataSource and delegate to my table view but the app just crashes. Im not sure how to get data to properly load into my table view when using a tableview in a different view. If anyone knows how to do this any help is appreciated. Thanks

  • Add new row to asp .net grid view using button

    - by SARAVAN
    Hi, I am working in ASP .net 2.0. I am a learner. I have a grid view which has a button in it. Please find the asp mark up below <form id="form1" runat="server"> <div> <asp:GridView ID="myGridView" runat="server"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:Button CommandName="AddARowBelow" Text="Add A Row Below" runat="server" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> </div> </form> Please find the code behind below. using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Data; using System.Web.UI.WebControls; namespace GridViewDemo { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { DataTable dt = new DataTable("myTable"); dt.Columns.Add("col1"); dt.Columns.Add("col2"); dt.Columns.Add("col3"); dt.Rows.Add(1, 2, 3); dt.Rows.Add(1, 2, 3); dt.Rows.Add(1, 2, 3); dt.Rows.Add(1, 2, 3); dt.Rows.Add(1, 2, 3); myGridView.DataSource = dt; myGridView.DataBind(); } protected void myGridView_RowCommand(object sender, GridViewCommandEventArgs e) { } } } I was thinking that when I click the command button, it would fire the mygridview_rowcommand() but instead it threw an error as follows: Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. Can any one let me know on where I am going wrong?

  • Logout from an desktop application to change user in C#.net

    - by Sadequzzaman Monoh
    I have designed an desktop application using C#.net that has many users. Each USer has specific rights. The User logs into the system when the application first starts and the UserID number is stored and used throughout the app., but when they want to change user (UserID) they have to close the system down and start again. How would I go about creating a 'log out' - 'login' function that keeps the main form open but disabled allowing a new user to login?

  • When should I use $ (and can it always be replaced with parentheses)?

    - by J Cooper
    From what I'm reading, $ is described as "applies a function to its arguments." However, it doesn't seem to work quite like (apply ...) in Lisp, because it's a binary operator, so really the only thing it looks like it does is help to avoid parentheses sometimes, like foo $ bar quux instead of foo (bar quux). Am I understanding it right? Is the latter form considered "bad style"?

  • Hadoop in a RESTful Java Web Application - Conflicting URI templates

    - by user1231583
    I have a small Java Web Application in which I am using Jersey 1.12 and the Hadoop 1.0.0 JAR file (hadoop-core-1.0.0.jar). When I deploy my application to my JBoss 5.0 server, the log file records the following error: SEVERE: Conflicting URI templates. The URI template / for root resource class org.apache.hadoop.hdfs.server.namenode.web.resources.NamenodeWebHdfsMethods and the URI template / transform to the same regular expression (/.*)? To make sure my code is not the problem, I have created a fresh web application that contains nothing but the Jersey and Hadoop JAR files along with a small stub. My web.xml is as follows: <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>ServletAdaptor</servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet- class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>ServletAdaptor</servlet-name> <url-pattern>/mytest/*</url-pattern> </servlet-mapping> <session-config> <session-timeout> 30 </session-timeout> </session-config> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app> My simple RESTful stub is as follows: import javax.ws.rs.core.Context; import javax.ws.rs.core.UriInfo; import javax.ws.rs.Path; @Path("/mytest") public class MyRest { @Context private UriInfo context; public MyRest() { } } In my regular application, when I remove the Hadoop JAR files (and the code that is using Hadoop), everything works as I would expect. The deployment is successful and the remaining RESTful services work. I have also tried the Hadoop 1.0.1 JAR files and have had the same problems with the conflicting URL template in the NamenodeWebHdfsMethods class. Any suggestions or tips in solving this problem would be greatly appreciated.

  • Any tricks to stop flickering in between page transitions?

    - by SLC
    Specifically, I am using a .hta to display pages. As the content is local, pages load instantly, but there is flicker as they redraw. Are there any tricks you can use to stop it flickering or reduce the effect? I heard somewhere that page transition effects can help, but does anyone have any ideas? Keep in mind that as its a .hta file, I have more flexibility, and can run vbscript etc. and do fancy things.
