  • OpenGL Mapping Textures to a Grid Stored Inside Vertex Array

    - by Matthew Hoggan
    I am writing a test to verify something. This is not production code, just verification code. So I would appreciate it if the specific question was answered. I have code that uses indices and vertices to draw a set of triangles in the shape of a grid. All the vertices are drawn using glDrawElements(). Now for each vertex I will set its corresponding Texture Coordinates to 0 or 1 for each set of triangles that form a square in the grid. Basically I want to draw a collage of random textures in each one of the "squares" (consisting of two triangles). I can do this using the glBegin() and glEnd() method calls inside a for loop using the fixed functional pipeline, but I would like to know how to do this using Vertex Arrays.

  • Long key press handling in android 1.5

    - by Kaillash
    Hi, I want to handle key press and long key press for the key code KEYCODE_BACK(back button). can any one suggest me how to do this in android 1.5(API level 3). Here is the code. public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_BACK) { if(event.getRepeatCount()==0) { // normal key press // But problem is, this code is hitting for long press also, how to avoid this } else { // Long key press //Do something here } // Always consume back key event by returning true //so that default behavior of back is overrided return true; } return super.onKeyDown(keyCode, event); }

  • Javascript - Function call will not enter function body

    - by Mike S
    I have a function acting as a constructor that, when called, gets as far as the function definition in the debugger, but never to the function body. Is there a common reason this may happen that I am overlooking? Example code below: myconstructor.js function MyConstructor(optionalParam) { //this breakpoint gets hit var newobj = {}; //breakpoint never hit //code to check for null parameter //other code }; main.js var myConstructor = new MyConstructor(); There must be something I have overlooked, but I can't see what that is. Neither firefox/firebug nor VS report errors or warnings. Thanks!

  • Safe ASCII char to replace whitespace before storing

    - by AngryWhenHungry
    My code passes a big bunch of text data to a legacy lib, which is responsible for storing it. However, it tends to remove trailing whitespace. This is a problem when I read the data back. Since I cannot change the legacy code, I thought about replacing the all spaces with some uncommon ASCII character. When I read back the text, I can replace them back. Is this a bad idea, considering that I cannot touch the legacy storage code? Which character can I use as a substitute? I was considering some char upwards of 180. There will only be spaces - no tabs or newlines - in the data. The data is alphanumeric, with special characters.

  • How to read the values returned by the Json?

    - by user281180
    I have the following code in my view: <% using (Ajax.BeginForm("JsonCreate", new AjaxOptions { OnComplete = "createCategoryComplete" })) { % Add new category <%=Html.TextBox("CategoryId")% <%=Html.TextBox("Test")% Name: <%= Html.TextBox("Name")% <%= Html.ValidationMessage("Name")% </p> <p> <input type="submit" value="Create" /> </p> </fieldset> </div> <% } % In the controller the code is as follows: [AcceptVerbs(HttpVerbs.Post)] public JsonResult JsonCreate(string Name) { if (ModelState.IsValid) { try { //Return a json object to the javascript return Json(new { CategoryId = 123, Test= "test successful" }); } catch { #region Log errors about the exception //Log error to administrator here #endregion } } //If we got this far, something failed, return an empty json object return Json(new { /* Empty object */ }); } What should be the code in the view for the following function to read the values returned by the Json and update the textboxes for CategoryId and Test? function createCategoryComplete() {....???}

  • Bind web user control property in markup

    - by Ian Levy
    I'm sure it's elementary but I can't figure it out. This does not work - the the binding expression is passed as string to the control: {<uc:usercontrol runtat="server" message='<%#Me.protectedVariable%>'/>} The code behind include a Page.Databind() call in page_load. But this does work: <uc:usercontrol runat="server" id="usercontrol1"/> And in code behind page_load: usercontrol1.message = Me.protectedVariable Do I have to bind from the code-behind? Is this a page life cycle issue?

  • Subquery vs Traditional join with WHERE clause?

    - by BradC
    When joining to a subset of a table, any reason to prefer one of these formats over the other? Subquery version: SELECT ... FROM Customers AS c INNER JOIN (SELECT * FROM Classification WHERE CustomerType = 'Standard') AS cf ON c.TypeCode = cf.Code INNER JOIN SalesReps s ON cf.SalesRepID = s.SalesRepID vs the WHERE clause at the end: SELECT ... FROM Customers AS c INNER JOIN Classification AS cf ON c.TypeCode = cf.Code INNER JOIN SalesReps AS s ON cf.SalesRepID = s.SalesRepID WHERE cf.CustomerType = 'Standard' The WHERE clause at the end feels more "traditional", but the first is arguably more clear, especially as the joins get increasingly complex. Only other reason I can think of to prefer the second is that the "SELECT *" on the first might be returning columns that aren't used later (In this case, I'd probably only need to return cf.Code and Cf.SalesRepID)

  • Where should I report mistakes in Android documentation?

    - by Nick
    Hi all, This is my first post ever -- I love the Android SDK (been at it for a week), but I did notice a small typo in the official documentation that needs correcting. Not sure if this is where I post it, but on this page: http://developer.android.com/reference/android/os/CountDownTimer.html within the example source code, the source says "CountdownTimer" on line one when it should say "CountDownTimer" (notice the capitalization of the letter "D"). An easy fix for one with programming experience, but the code as written will not compile, which could be confusing for someone using this code for the first time. Is this where documentation bugs are submitted, and if not, where should I go to request the fix? Thanks all!

  • Keeping track of threads when creating them recursively

    - by 66replica
    I'm currently working on some code for my Programming Languages course. I can't post the code but I'm permitted to talk about some high level concepts that I'm struggling with and receive input on them. Basically the code is a recursive DFS on a undirected graph that I'm supposed to convert to a concurrent program. My professor already specified that I should create my threads in the recursive DFS method and then join them in another method. Basically, I'm having trouble thinking of how I should keep track of the threads I'm creating so I can join all of them in the other method. I'm thinking an array of Threads but I'm unsure how to add each new thread to the array or even if that's the right direction.

  • How do I show the number of images attached to a post on the image attachment page?

    - by mattloak
    I use the image attachment page to show images attached to a post one by one, in a slideshow sort of affect. I'd like to be able to display the total number of images attached to the parent post and the number of the particular image that's being shown on any given attachment page so you see the picture and the words "Image 3 of 15" for example. I've played around with some different code and can get the total number of images to show on the post page, but when I insert the code on the attachment page template it always shows "1 of 1." I was having this problem a while ago and decided to re-address it, unfortunately I don't have the original code that I used and can't remember it. Anyone have any suggestions?

  • Automatic Step over

    - by Vaccano
    I have been getting this error message when I step into some methods Do you want to continue being notified when an Automatic step over occurs? I usually answer Yes and I get taken to the line I want to step to. However, I just pressed No (cause I was tired of the dialog box always popping up). When I did that it skipped a lot of code I wanted to step through. Now when I step into my method it is skipping my method (and jumping to the finally block because the method I am trying to step into is throwing an exception). How can I change my answer back to Yes? I would prefer it never ask me (default showing the code), but if faced with the choice of it skipping the code I need to see, or having a NagBox, I will take the NagBox.

  • How do I get stdout into mstest output when running in new app domain?

    - by btlog
    I have been working on test framework, which creates a new app domain to run the tests in. The primary reason being the dll's that we are testing has some horrible code that relies on the dll being located in the app domain path. (No I can't change this code.) The problem that I am having is that my test team is writing a bunch of functional tests in mstest and one of the loggers, that writes to Console.Out, does not have any of the log information captured in the trx output. When running the code through a console app all of the log information is output fine. So do the other loggers that have been implemented. My thought is that mstest is setting its own TextWriter to Console.Out, but the new app doamin has it's own TextWriter for Console.Out as the new app domain has it's own set of statics. I appreciate your ideas.

  • What is the business case for a dependency injection (DI) framework?

    - by kalkie
    At my company we want to start using a dependency injection (DI) framework for managing our dependencies. I have some difficulty with explaining the business value of such a framework. Currently I have come up with these reasons. Less source code, delete all the builder patterns in the code. Increase in flexibility. Easier to switch dependencies. Better separation of concern. The framework is responsible for creating instances instead of our code. Has anybody else had to persuade management? How did you do that? What reasons did you use?

  • SubSonic Change DropDown Value for Load Drops SUB

    - by GTJR
    I used the subsonic generator to create some aspx pages, It works fine. On some of the pages it automaticaly generated the dropdown boxes for foreign key values. How Can change that value in the load drops code? Or where I need to change it. For instance I have a workers table and a workersweek table. The workers table has a workerid,firstname and lastname field and the workersweek has a workerID field. The generator automatically set it up to show the firstname in the dropdown. I want to change the value to be both firstname and lastname. I am sure I will have to add code that does something like firstname + " " + Lastname. I am just not sure where to do it withing the code that was generated. I see the load drops sub, but it does not seem like that is the one I need to modify.

  • Get html that is generated via AJAX in C# webclient

    - by WebDevHobo
    I often go to a site to look stuff up. I thought to myself: "Hold on. I can program. Why am I going to this site manually when I can write a piece of software that does it for me?". And so I started. I'm using C#, so I found WebClient and Uri. I've managed to get the source code for the site, yet the problem occurred that the specific data I'm looking for is generated via AJAX, after the source code has loaded. So that's my problem. How can I get that code, if it needs to be requested via an AJAX call first?

  • jQuery display problem?

    - by SLAPme
    How do I hide the #changes-saved code using jQuery? For example let's say the code is displayed when the user clicks the submit button and then leaves the current web page and then returns back to the web page and the #changes-saved is no longer displayed until the submit button is clicked again. Here is the jQuery code. $(function() { $('#changes-saved').hide(); $(".save-button").click(function() { $.post($("#contact-form").attr("action"), $("#contact-form").serialize(), function(html) { $("div.contact-info-form").html(html); $('#changes-saved').append('<li>Changes saved!</li>').show().pause(1000).hide(); }); return false; // Prevent normal submit. }); });

  • Idea for doing almost same work in both catch & finally(C#3.0)

    - by Newbie
    I have a requirement. I am processing some files and after the processing are done I am archiving those files into an archive folder with timestamp appended. The file archiving and putting time stamp portion I am doing in the Finally block. Now a new requirement has come where I need to mail if something wrong goes in the original files and then I need to archive the same. Now this piece of code I need to handle in the catch block. But if I write the code entirely in the catch block, then it will fire only if there is an exception; otherwise not. So basically I am writing the same pice of code in both the catch and finally block. What is the standard and recommended approach you people think will be better in this case? I am using C#3.0 Thanks.

Can anyone suggest how i could amend this code to get rid of the message? Thanks in advance $data = stristr("$text", "$key"); $result = string_limit_words($data,2); print "$result<BR>";
