  • How to create a level with curved lines with cocos2d + Box2d on the iphone?

    - by Steven
    I'd like to create a game that has levels such as this: http://img169.imageshack.us/img169/7294/picdq.png The Player moves "flies" through the level and mustn't collide with the walls. How can I create such levels? I found that piece of software: http://www.sapusmedia.com/levelsvg/ It's not that cheap, so I wonder whether there is another way to create such a level as shown in the picture above...?

  • HttpWebRequest possibly slowing website

    - by Steven Smith
    Using Visual studio 2012, C#.net 4.5 , SQL Server 2008, Feefo, Nopcommerce Hey guys I have Recently implemented a new review service into a current site we have. When the change went live the first day all worked fine. Since then though the sending of sales to Feefo hasnt been working, There are no logs either of anything going wrong. In the OrderProcessingService.cs in Nop Commerce's Service, i call a HttpWebrequest when an order has been confirmed as completed. Here is the code. var email = HttpUtility.UrlEncode(order.Customer.Email.ToString()); var name = HttpUtility.UrlEncode(order.Customer.GetFullName().ToString()); var description = HttpUtility.UrlEncode(productVariant.ProductVariant.Product.MetaDescription != null ? productVariant.ProductVariant.Product.MetaDescription.ToString() : "product"); var orderRef = HttpUtility.UrlEncode(order.Id.ToString()); var productLink = HttpUtility.UrlEncode(string.Format("myurl/p/{0}/{1}", productVariant.ProductVariant.ProductId, productVariant.ProductVariant.Name.Replace(" ", "-"))); string itemRef = ""; try { itemRef = HttpUtility.UrlEncode(productVariant.ProductVariant.ProductId.ToString()); } catch { itemRef = "0"; } var url = string.Format("feefo Url", login, password,email,name,description,orderRef,productLink,itemRef); var request = (HttpWebRequest)WebRequest.Create(url); request.KeepAlive = false; request.Timeout = 5000; request.Proxy = null; using (var response = (HttpWebResponse)request.GetResponse()) { if (response.StatusDescription == "OK") { var stream = response.GetResponseStream(); if(stream != null) { using (var reader = new StreamReader(stream)) { var content = reader.ReadToEnd(); } } } } So as you can see its a simple webrequest that is processed on an order, and all product variants are sent to feefo. Now: this hasnt been happening all week since the 15th (day of the implementation) the site has been grinding to a halt recently. The stream and reader in the the var content is there for debugging. Im wondering does the code redflag anything to you that could relate to the process of website? Also note i have run some SQL statements to see if there is any deadlocks or large escalations, so far seems fine, Logs have also been fine just the usual logging of Bots. Any help would be much appreciated! EDIT: also note that this code is in a method that is called and wrapped in A try catch UPDATE: well forget about the "not sending", thats because i was just told my code was rolled back last week

  • drupal display submenu when parent has been selected

    - by Steven Cheng
    I've have a menu structure that has a depth of 3 levels on a drupal 6 CMS. When I click on a level 1 that has children, the level 2 menu items display fine. If the level 2 has children, it is not showing the level 3. If I check the expanded box the level 3 is displayed however, it displays all the time irrespective of the level 2 that has been selected. It seems to display whenever it's parent level 1 is selected. For further information, the menu items are a mixture of custom links & content links. i.e. Links I've enetered manually when creating the menu and others generated by when creating a node or view display. All I want is to show the children if there are any for the selected parent. Am I missing something fundamental here? Thanks Steve

  • Inconsistent Behavior From Declared DLL Function

    - by Steven
    Why might my GetRawData declared function return a correct value when called from my VB.NET application, but return zero when called from my ASP.NET page? The code is exactly the same except for class type difference (Form / Page) and calling event handler (Form1_Load, Page_Load). Note: In the actual code, #DLL# and #RAWDATAFILE# are both absolute filenames to my DLL and raw data file respectively. Note: The DLL file was not created by Visual Studio. Form1.vb Public Class Form1 Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Private Sub Form1_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length) Default.aspx.vb Partial Public Class _Default Inherits System.Web.UI.Page Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Me.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length)

  • Django - Static content display based on URL

    - by Steven Potter
    I'm working on a Django site with a basic three column design. Left column navigation, center column content and right column URL specific content blocks. My question is about the best method of controlling the URL specific content blocks in the right column. I am thinking of something along the lines of the Flatpages app that will make the content available to the template context if the URL matches a pre-determined pattern (perhaps regex?). Does anyone know if such an app already exists? If not, I am looking for some advice about the best way to implement it. Particularly in relation to the matching of patterns to the current URL. Is there any good way to re-use parts of the Django URL dispatcher for this use?

  • Multithreading with STL container

    - by Steven
    I have an unordered map which stores a pointer of objects. I am not sure whether I am doing the correct thing to maintain the thread safety. typedef std::unordered_map<string, classA*>MAP1; MAP1 map1; pthread_mutex_lock(&mutexA) if(map1.find(id) != map1.end()) { pthread_mutex_unlock(&mutexA); //already exist, not adding items } else { classA* obj1 = new classA; map1[id] = obj1; obj1->obtainMutex(); //Should I create a mutex for each object so that I could obtain mutex when I am going to update fields for obj1? pthread_mutex_unlock(&mutexA); //release mutex for unordered_map so that other threads could access other object obj1->field1 = 1; performOperation(obj1); //takes some time obj1->releaseMutex(); //release mutex after updating obj1 }

  • Cannot Generate ParameterSetMetadata While Programmatically Creating A Parameter Block

    - by Steven Murawski
    I'm trying to programmatically create a parameter block for a function ( along the lines of this blog post ). I'm starting with a CommandMetadata object (from an existing function). I can create the ParameterMetadata object and set things like the ParameterType, the name, as well as some attributes. The problem I'm running into is that when I use the GetParamBlock method of the ProxyCommand class, none of my attributes that I set in the Attributes collection of the ParameterMetadata are generated. The problem this causes is that when the GetParamBlock is called, the new parameter is not annotated with the appropriate Parameter attribute. Example: function test { [CmdletBinding()] param ( [Parameter()] $InitialParameter) Write-Host "I don't matter." } $MetaData = New-Object System.Management.Automation.CommandMetaData (get-command test) $NewParameter = New-Object System.Management.Automation.ParameterMetadata 'NewParameter' $NewParameter.ParameterType = [string[]] $Attribute = New-Object System.Management.Automation.ParameterAttribute $Attribute.Position = 1 $Attribute.Mandatory = $true $Attribute.ValueFromPipeline = $true $NewParameter.Attributes.Add($Attribute) $MetaData.Parameters.Add('NewParameter', $NewParameter) [System.Management.Automation.ProxyCommand]::GetParamBlock($MetaData)

  • jQuery dialog box not opening 2nd time

    - by Steven
    I found this thread which basically has the same issue I have. But their solution is not working for me. The dialog appears the first time I click the submit button, but not the 2nd time. I'm opening the dialog box after a form submission. UPDATE I finally got it working. Here is the correct code: if (jQuery('#registrationforms').length > 0) { //instantiate the dialog jQuery("#dialog").dialog({ modal:true, autoOpen:false }); //Some more code here to call processRegistration function. } function processRegistration(instanceID, formData) { jQuery.post("mypath/jquery_bll.php", { instance: 'processRegistration', formData : formData, instanceID : instanceID }, function(feedback) { jQuery('#dialog').text(feedback.message); jQuery('#dialog').parent().addClass(feedback.type); jQuery('#dialog').dialog('open'); },"json"); } Since I'm dynamically applying css class, I have to make sure to add it to the outer DIV which $.dialog creates to wrap my 'dialog' DIV.

  • How to make multiple windows using Win32 API

    - by Steven Lu
    I see plenty of tutorials and articles showing me how to make a simple windows program, which is great but none of them show me how to make multiple windows. Right now I have working code that creates and draws a layered window and I can blit stuff using GDI to draw anything I want on it, drag it around, even make it transparent, etc. But I wanted a second rectangular area that I can draw to, drag around, etc. In other words, a second window. Probably want it to be a child window. Question is, how do I make it? Also, if anybody knows any good resources (online preferably) like articles or tutorials for window management in the Windows API, please share.

  • getopt implicit declaration in Solaris?

    - by Steven
    In Solaris, gcc gives me implicit declaration of function `getopt' when compiling #include <unistd.h> #include <stdlib.h> int main(int argc, char *argv[]) { getopt(1,argv,""); return 0; } The man page for getopt says something about including unistd.h or stdio.h, however even though I'm inluding both I still get this warning. Is this normal? Is using functions that aren't explicitly declared common in Unix development?

    I'm expanding Wordpress to function more like a CMS. This includes relating image to a post. Currently I have a text field where I paste an image path. Now I want to click a button which opens a dialog box, then I navigate to the right folder and select a file to "open" (from server side). The file path is returned. How can I go about accomplishing this?

  • jQuery - Wait until image loads before performing function

    - by Steven
    I'm trying to create a simple portfolio page. I have a list of thumbs and an image. When you click on a thumb, the image will change. When a thumbnail is clicked, I'd like to have the image fade out, wait until the image is loaded, then fade back in. The problem I have right now is that some of the images are pretty big, so it fades out, then fades back in immediately, sometimes while the image is still loading. I'd like to avoid using setTimeout, since sometimes an image will load faster or slower than the time I set. Here's my code: $(function() { $('img#image').attr("src", $('ul#thumbs li:first img').attr("src")); $('ul#thumbs li img').click(function() { $('img#image').fadeOut(700); var src = $(this).attr("src"); $('img#image').attr("src", src); $('img#image').fadeIn(700); }); }); <img id="image" src="" alt="" /> <ul id="thumbs"> <li><img src="/images/thumb1.png" /></li> <li><img src="/images/thumb2.png" /></li> <li><img src="/images/thumb3.png" /></li> </ul>

  • How to join 2 tables & display them correctly?

    - by steven
    http://img293.imageshack.us/img293/857/tablez.jpg Here is a picture of the 2 tables. The mybb_users table is the table that has the users that signed up for the forum. The mybb_userfields is the table that contain custom profile field data that they are able to customize & change in their profile. Now, all I want to do is display all users in rows with the custom profile field data that they provided in their profile(which is in the mybb_userfields table) How can I display these fields correctly together? For instance, p0gz is a male,lives in AZ,he owns a 360,does not know his bandwidth & Flip Side Phoenix is his team. How can it just be like "p0gz-male-az-360-dont know-flipside phoenix" in a row~???

  • Relocating html elements with jquery

    - by Steven
    Could someone help me with this code? I'm trying to rearrange figures in a certain div into two columns (a and b) in such a way the two columns are about the same height. I've got insane trying to find the problem in my code and not finding it. It doesn't work for a reason... <body onload="rearrangeImages();"> <div class="images"> <figure> <figcaption>This is the figcaption of this figure. An image is missing for this test.</figcaption> </figure> <figure> <figcaption>This is the figcaption of this figure.</figcaption> </figure> <figure> <figcaption>Another one.</figcaption> </figure> </div> <script> function rearrangeImages() { $('.images').each(function() { $(this).prepend('<div class="column_b"></div>'); $(this).prepend('<div class="column_a"></div>'); $(this).append('<div class="test_div"></div>'); $('figure', this).each(function() { var height_a = $(this).parent().$(".column_a").height(); var height_b = $(this).parent().$(".column_b").height(); if (height_a > height_b) { $(this).parent().$(".column_b").append(this); } else { $(this).parent().$(".column_a").append(this); } $(this).remove(); }); }); } </script> </body> Next I would like to be able to make the last figure not going in any of the columns in case it would make column_b higher than column_a. (pseudocode) if (this is last figure) { //place last figure in test_div to measure its height; if (height_a > height_b + height_of_last_image) { $(this).parent().$(".column_b").append(this); } else { $(this).parent().append(this); } } else { //do the normal stuff see higher }
