  • Copying one form's values to another form using JQuery

    - by rsturim
    I have a "shipping" form that I want to offer users the ability to copy their input values over to their "billing" form by simply checking a checkbox. I've coded up a solution that works -- but, I'm sort of new to jQuery and wanted some criticism on how I went about achieving this. Is this well done -- any refactorings you'd recommend? Any advice would be much appreciated! The Script <script type="text/javascript"> $(function() { $("#copy").click(function() { if($(this).is(":checked")){ var $allShippingInputs = $(":input:not(input[type=submit])", "form#shipping"); $allShippingInputs.each(function() { var billingInput = "#" + this.name.replace("ship", "bill"); $(billingInput).val($(this).val()); }) //console.log("checked"); } else { $(':input','#billing') .not(':button, :submit, :reset, :hidden') .val('') .removeAttr('checked') .removeAttr('selected'); //console.log("not checked") } }); }); </script> The Form <div> <form action="" method="get" name="shipping" id="shipping"> <fieldset> <legend>Shipping</legend> <ul> <li> <label for="ship_first_name">First Name:</label> <input type="text" name="ship_first_name" id="ship_first_name" value="John" size="" /> </li> <li> <label for="ship_last_name">Last Name:</label> <input type="text" name="ship_last_name" id="ship_last_name" value="Smith" size="" /> </li> <li> <label for="ship_state">State:</label> <select name="ship_state" id="ship_state"> <option value="RI">Rhode Island</option> <option value="VT" selected="selected">Vermont</option> <option value="CT">Connecticut</option> </select> </li> <li> <label for="ship_zip_code">Zip Code</label> <input type="text" name="ship_zip_code" id="ship_zip_code" value="05401" size="8" /> </li> <li> <input type="submit" name="" /> </li> </ul> </fieldset> </form> </div> <div> <form action="" method="get" name="billing" id="billing"> <fieldset> <legend>Billing</legend> <ul> <li> <input type="checkbox" name="copy" id="copy" /> <label for="copy">Same of my shipping</label> </li> <li> <label for="bill_first_name">First Name:</label> <input type="text" name="bill_first_name" id="bill_first_name" value="" size="" /> </li> <li> <label for="bill_last_name">Last Name:</label> <input type="text" name="bill_last_name" id="bill_last_name" value="" size="" /> </li> <li> <label for="bill_state">State:</label> <select name="bill_state" id="bill_state"> <option>-- Choose State --</option> <option value="RI">Rhode Island</option> <option value="VT">Vermont</option> <option value="CT">Connecticut</option> </select> </li> <li> <label for="bill_zip_code">Zip Code</label> <input type="text" name="bill_zip_code" id="bill_zip_code" value="" size="8" /> </li> <li> <input type="submit" name="" /> </li> </ul> </fieldset> </form> </div>

  • Watching a variable for changes without polling.

    - by milkfilk
    I'm using a framework called Processing which is basically a Java applet. It has the ability to do key events because Applet can. You can also roll your own callbacks of sorts into the parent. I'm not doing that right now and maybe that's the solution. For now, I'm looking for a more POJO solution. So I wrote some examples to illustrate my question. Please ignore using key events on the command line (console). Certainly this would be a very clean solution but it's not possible on the command line and my actual app isn't a command line app. In fact, a key event would be a good solution for me but I'm trying to understand events and polling beyond just keyboard specific problems. Both these examples flip a boolean. When the boolean flips, I want to fire something once. I could wrap the boolean in an Object so if the Object changes, I could fire an event too. I just don't want to poll with an if() statement unnecessarily. import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; /* * Example of checking a variable for changes. * Uses dumb if() and polls continuously. */ public class NotAvoidingPolling { public static void main(String[] args) { boolean typedA = false; String input = ""; System.out.println("Type 'a' please."); while (true) { InputStreamReader isr = new InputStreamReader(System.in); BufferedReader br = new BufferedReader(isr); try { input = br.readLine(); } catch (IOException ioException) { System.out.println("IO Error."); System.exit(1); } // contrived state change logic if (input.equals("a")) { typedA = true; } else { typedA = false; } // problem: this is polling. if (typedA) System.out.println("Typed 'a'."); } } } Running this outputs: Type 'a' please. a Typed 'a'. On some forums people suggested using an Observer. And although this decouples the event handler from class being observed, I still have an if() on a forever loop. import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.util.Observable; import java.util.Observer; /* * Example of checking a variable for changes. * This uses an observer to decouple the handler feedback * out of the main() but still is polling. */ public class ObserverStillPolling { boolean typedA = false; public static void main(String[] args) { // this ObserverStillPolling o = new ObserverStillPolling(); final MyEvent myEvent = new MyEvent(o); final MyHandler myHandler = new MyHandler(); myEvent.addObserver(myHandler); // subscribe // watch for event forever Thread thread = new Thread(myEvent); thread.start(); System.out.println("Type 'a' please."); String input = ""; while (true) { InputStreamReader isr = new InputStreamReader(System.in); BufferedReader br = new BufferedReader(isr); try { input = br.readLine(); } catch (IOException ioException) { System.out.println("IO Error."); System.exit(1); } // contrived state change logic // but it's decoupled now because there's no handler here. if (input.equals("a")) { o.typedA = true; } } } } class MyEvent extends Observable implements Runnable { // boolean typedA; ObserverStillPolling o; public MyEvent(ObserverStillPolling o) { this.o = o; } public void run() { // watch the main forever while (true) { // event fire if (this.o.typedA) { setChanged(); // in reality, you'd pass something more useful notifyObservers("You just typed 'a'."); // reset this.o.typedA = false; } } } } class MyHandler implements Observer { public void update(Observable obj, Object arg) { // handle event if (arg instanceof String) { System.out.println("We received:" + (String) arg); } } } Running this outputs: Type 'a' please. a We received:You just typed 'a'. I'd be ok if the if() was a NOOP on the CPU. But it's really comparing every pass. I see real CPU load. This is as bad as polling. I can maybe throttle it back with a sleep or compare the elapsed time since last update but this is not event driven. It's just less polling. So how can I do this smarter? How can I watch a POJO for changes without polling? In C# there seems to be something interesting called properties. I'm not a C# guy so maybe this isn't as magical as I think. private void SendPropertyChanging(string property) { if (this.PropertyChanging != null) { this.PropertyChanging(this, new PropertyChangingEventArgs(property)); } }

  • Trouble with copying dictionaries and using deepcopy on an SQLAlchemy ORM object

    - by Az
    Hi there, I'm doing a Simulated Annealing algorithm to optimise a given allocation of students and projects. This is language-agnostic pseudocode from Wikipedia: s ? s0; e ? E(s) // Initial state, energy. sbest ? s; ebest ? e // Initial "best" solution k ? 0 // Energy evaluation count. while k < kmax and e > emax // While time left & not good enough: snew ? neighbour(s) // Pick some neighbour. enew ? E(snew) // Compute its energy. if enew < ebest then // Is this a new best? sbest ? snew; ebest ? enew // Save 'new neighbour' to 'best found'. if P(e, enew, temp(k/kmax)) > random() then // Should we move to it? s ? snew; e ? enew // Yes, change state. k ? k + 1 // One more evaluation done return sbest // Return the best solution found. The following is an adaptation of the technique. My supervisor said the idea is fine in theory. First I pick up some allocation (i.e. an entire dictionary of students and their allocated projects, including the ranks for the projects) from entire set of randomised allocations, copy it and pass it to my function. Let's call this allocation aOld (it is a dictionary). aOld has a weight related to it called wOld. The weighting is described below. The function does the following: Let this allocation, aOld be the best_node From all the students, pick a random number of students and stick in a list Strip (DEALLOCATE) them of their projects ++ reflect the changes for projects (allocated parameter is now False) and lecturers (free up slots if one or more of their projects are no longer allocated) Randomise that list Try assigning (REALLOCATE) everyone in that list projects again Calculate the weight (add up ranks, rank 1 = 1, rank 2 = 2... and no project rank = 101) For this new allocation aNew, if the weight wNew is smaller than the allocation weight wOld I picked up at the beginning, then this is the best_node (as defined by the Simulated Annealing algorithm above). Apply the algorithm to aNew and continue. If wOld < wNew, then apply the algorithm to aOld again and continue. The allocations/data-points are expressed as "nodes" such that a node = (weight, allocation_dict, projects_dict, lecturers_dict) Right now, I can only perform this algorithm once, but I'll need to try for a number N (denoted by kmax in the Wikipedia snippet) and make sure I always have with me, the previous node and the best_node. So that I don't modify my original dictionaries (which I might want to reset to), I've done a shallow copy of the dictionaries. From what I've read in the docs, it seems that it only copies the references and since my dictionaries contain objects, changing the copied dictionary ends up changing the objects anyway. So I tried to use copy.deepcopy().These dictionaries refer to objects that have been mapped with SQLA. Questions: I've been given some solutions to the problems faced but due to my über green-ness with using Python, they all sound rather cryptic to me. Deepcopy isn't playing nicely with SQLA. I've been told thatdeepcopy on ORM objects probably has issues that prevent it from working as you'd expect. Apparently I'd be better off "building copy constructors, i.e. def copy(self): return FooBar(....)." Can someone please explain what that means? I checked and found out that deepcopy has issues because SQLAlchemy places extra information on your objects, i.e. an _sa_instance_state attribute, that I wouldn't want in the copy but is necessary for the object to have. I've been told: "There are ways to manually blow away the old _sa_instance_state and put a new one on the object, but the most straightforward is to make a new object with __init__() and set up the attributes that are significant, instead of doing a full deep copy." What exactly does that mean? Do I create a new, unmapped class similar to the old, mapped one? An alternate solution is that I'd have to "implement __deepcopy__() on your objects and ensure that a new _sa_instance_state is set up, there are functions in sqlalchemy.orm.attributes which can help with that." Once again this is beyond me so could someone kindly explain what it means? A more general question: given the above information are there any suggestions on how I can maintain the information/state for the best_node (which must always persist through my while loop) and the previous_node, if my actual objects (referenced by the dictionaries, therefore the nodes) are changing due to the deallocation/reallocation taking place? That is, without using copy?

  • Trying to draw 2 objects on screen and store the selected item names in an array

    - by thefonso
    Ok...this is a homework question, here is what i'm asked to do.... "Allow the user to draw two Shapes, which when instantiated, get put into the array myShapes...(store the shapes in the createShape() method." I want to know if I'm going in the right direction. Do I need to modify only Model.java or GUIDemo.java as well? Am I sufficient in thinking of only storing the values for the array via a loop inside my createShape() method?

  • migrating from Prototype to jQuery in Rails, having trouble with duplicate get request

    - by aressidi
    I'm in the process of migrating from Prototype to jQuery and moving all JS outside of the view files. All is going fairly well with one exception. Here's what I'm trying to do, and the problem I'm having. I have a diary where users can update records in-line in the page like so: user clicks 'edit' link to edit an entry in the diary a get request is performed via jQuery and an edit form is displayed allowing the user to modify the record user updates the record, the form disappears and the updated record is shown in place of the form All of that works so far. The problem arises when: user updates a record user clicks 'edit' to update another record in this case, the edit form is shown twice! In firebug I get a status code 200 when the form shows, and then moments later, another edit form shows again with a status code of 304 I only want the form to show once, not twice. The form shows twice only after I update a record, otherwise everything works fine. Here's the code, any ideas? I think this might have to do with the fact that in food_item_update.js I call the editDiaryEntry() after a record is updated, but if I don't call that function and try and update the record after it's been modified, then it just spits up the .js.erb response on the screen. That's also why I have the editDiaryEntry() in the add_food.js.erb file. Any help would be greatly appreciated. diary.js jQuery(document).ready(function() { postFoodEntry(); editDiaryEntry(); initDatePicker(); }); function postFoodEntry() { jQuery('form#add_entry').submit(function(e) { e.preventDefault(); jQuery.post(this.action, jQuery(this).serialize(), null, "script"); // return this }); } function editDiaryEntry() { jQuery('.edit_link').click(function(e) { e.preventDefault(); // This should look to see if one version of this is open... if (jQuery('#edit_container_' + this.id).length == 0 ) { jQuery.get('/diary/entry/edit', {id: this.id}, null, "script"); } }); } function closeEdit () { jQuery('.close_edit').click(function(e) { e.preventDefault(); jQuery('.entry_edit_container').remove(); jQuery("#entry_" + this.id).show(); }); } function updateDiaryEntry() { jQuery('.edit_entry_form').submit(function(e) { e.preventDefault(); jQuery.post(this.action, $(this).serialize(), null, "script"); }); } function initDatePicker() { jQuery("#date, #edit_date").datepicker(); }; add_food.js.erb jQuery("#entry_alert").show(); jQuery('#add_entry')[ 0 ].reset(); jQuery('#diary_entries').html("<%= escape_javascript(render :partial => 'members/diary/diary_entries', :object => @diary, :locals => {:record_counter => 0, :date_header => 0, :edit_mode => @diary_edit}, :layout => false ) %>"); jQuery('#entry_alert').html("<%= escape_javascript(render :partial => 'members/diary/entry_alert', :locals => {:type => @type, :message => @alert_message}) %>"); jQuery('#entry_alert').show(); setTimeout(function() { jQuery('#entry_alert').fadeOut('slow'); }, 5000); editDiaryEntry(); food_item_edit.js.erb jQuery("#entry_<%= @entry.id %>").hide(); jQuery("#entry_<%= @entry.id %>").after("<%= escape_javascript(render :partial => 'members/diary/food_item_edit', :locals => {:user_food_profile => @entry}) %>"); closeEdit(); updateDiaryEntry(); initDatePicker(); food_item_update.js jQuery("#entry_<%= @entry.id %>").replaceWith("<%= escape_javascript(render :partial => 'members/diary/food_item', :locals => {:entry => @entry, :total_calories => 0}) %>"); jQuery('.entry_edit_container').remove(); editDiaryEntry();

  • Returning Json object from controller action to jQuery

    - by PsychoCoder
    I'm attempting to get this working properly (2 days now). I'm working on a log in where I'm calling the controller action from jQuery, passing it a JSON object (utilizing json2.js) and returning a Json object from the controller. I'm able to call the action fine, but instead of being able to put the response where I want it it just opens a new window with this printed on the screen: {"Message":"Invalid username/password combination"} And the URL looks like http://localhost:13719/Account/LogOn so instead of calling the action and not reloading the page it's taking the user to the controller, which isn't good. So now for some code, first the controller code [HttpPost] public ActionResult LogOn(LogOnModel model, string returnUrl = "") { if (ModelState.IsValid) { var login = ObjectFactory.GetInstance<IRepository<PhotographerLogin>>(); var user = login.FindOne(x => x.Login == model.Username && x.Pwd == model.Password); if (user == null) return Json(new FailedLoginViewModel { Message = "Invalid username/password combination" }); else { if (!string.IsNullOrEmpty(returnUrl)) return Redirect(returnUrl); else return RedirectToAction("Index", "Home"); } } return RedirectToAction("Index", "Home"); } And the jQuery code $("#signin_submit").click(function () { var login = getLogin(); $.ajax({ type: "POST", url: "../Account/LogOn", data: JSON.stringify(login), dataType: 'json', contentType: 'application/json; charset=utf-8', error: function (xhr) { $("#message").text(xhr.statusText); }, success: function (result) { } }); }); function getLogin() { var un = $("#username").val(); var pwd = $("#password").val(); var rememberMe = $("#rememberme").val(); return (un == "") ? null : { Username: un, Password: pwd, RememberMe: rememberMe }; } In case you need to see the actual login form here that is as well <fieldset id="signin_menu"> <div> <span id="message"></span> </div> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm("LogOn", "Account", FormMethod.Post, new { @id = "signin" })) {%> <% ViewContext.FormContext.ValidationSummaryId = "valLogOnContainer"; %> <%= Html.LabelFor(m => m.Username) %> <%= Html.TextBoxFor(m => m.Username, new { @class = "inputbox", @tabindex = "4", @id = "username" })%><%= Html.ValidationMessageFor(m => m.Username, "*")%> <p> <%= Html.LabelFor(m=>m.Password) %> <%= Html.PasswordFor(m => m.Password, new { @class = "inputbox", @tabindex = "5", @id = "password" })%><%= Html.ValidationMessageFor(m => m.Password, "*")%> </p> <p class="remember"> <input id="signin_submit" value="Sign in" tabindex="6" type="submit"/> <%= Html.CheckBoxFor(m => m.RememberMe, new { @class = "inputbox", @tabindex = "7", @id = "rememberme" })%> <%= Html.LabelFor(m => m.RememberMe) %> <p class="forgot"> <a href="#" id="forgot_password_link" title="Click here to reset your password.">Forgot your password?</a> </p> <p class="forgot-username"> <a href="#" id="forgot_username_link" title="Fogot your login name? We can help with that">Forgot your username?</a> </p> </p> <%= Html.ValidationSummaryJQuery("Please fix the following errors.", new Dictionary<string, object> { { "id", "valLogOnContainer" } })%> <% } %> </fieldset> The login form is loaded on the main page with <% Html.RenderPartial("LogonControl");%> Not sure if that has any bearing on this or not but thought I'd mention it. EDIT: The login form is loaded similar to the Twitter login, click a link and the form loads with the help of jQuery & CSS

  • JSF2 - use view scope managed bean to pass value between navigation

    - by Fekete Kamosh
    Hi all, I am solving how to pass values from one page to another without making use of session scope managed bean. For most managed beans I would like to have only Request scope. I created a very, very simple calculator example which passes Result object resulting from actions on request bean (CalculatorRequestBean) from 5th phase as initializing value for new instance of request bean initialized in next phase lifecycle. In fact - in production environment we need to pass much more complicated data object which is not as primitive as Result defined below. What is your opinion on this solution which considers both possibilities - we stay on the same view or we navigate to the new one. But in both cases I can get to previous value stored passed using view scoped managed bean. Calculator page: <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html"> <h:head> <title>Calculator</title> </h:head> <h:body> <h:form> <h:panelGrid columns="2"> <h:outputText value="Value to use:"/> <h:inputText value="#{calculatorBeanRequest.valueToAdd}"/> <h:outputText value="Navigate to new view:"/> <h:selectBooleanCheckbox value="#{calculatorBeanRequest.navigateToNewView}"/> <h:commandButton value="Add" action="#{calculatorBeanRequest.add}"/> <h:commandButton value="Subtract" action="#{calculatorBeanRequest.subtract}"/> <h:outputText value="Result:"/> <h:outputText value="#{calculatorBeanRequest.result.value}"/> <h:outputText value="DUMMY" rendered="#{resultBeanView.dummy}"/> </h:panelGrid> </h:form> </h:body> Object to be passed through lifecycle: package cz.test.calculator; import java.io.Serializable; /** * Data object passed among pages. * Lets imagine it holds something much more complicated than primitive int */ public class Result implements Serializable { private int value; public void setValue(int value) { this.value = value; } public int getValue() { return value; } } Request scoped managed bean used on view "calculator.xhtml" package cz.test.calculator; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ManagedProperty; import javax.faces.bean.RequestScoped; @ManagedBean @RequestScoped public class CalculatorBeanRequest { @ManagedProperty(value="#{resultBeanView}") ResultBeanView resultBeanView; private Result result; private int valueToAdd; /** * Should perform navigation to */ private boolean navigateToNewView; /** Creates a new instance of CalculatorBeanRequest */ public CalculatorBeanRequest() { } @PostConstruct public void init() { // Remember already saved result from view scoped bean result = resultBeanView.getResult(); } // Dependency injections public void setResultBeanView(ResultBeanView resultBeanView) { this.resultBeanView = resultBeanView; } public ResultBeanView getResultBeanView() { return resultBeanView; } // Getters, setter public void setValueToAdd(int valueToAdd) { this.valueToAdd = valueToAdd; } public int getValueToAdd() { return valueToAdd; } public boolean isNavigateToNewView() { return navigateToNewView; } public void setNavigateToNewView(boolean navigateToNewView) { this.navigateToNewView = navigateToNewView; } public Result getResult() { return result; } // Actions public String add() { result.setValue(result.getValue() + valueToAdd); return isNavigateToNewView() ? "calculator" : null; } public String subtract() { result.setValue(result.getValue() - valueToAdd); return isNavigateToNewView() ? "calculator" : null; } } and finally view scoped managed bean to pass Result variable to new page: package cz.test.calculator; import java.io.Serializable; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; import javax.faces.context.FacesContext; @ManagedBean @ViewScoped public class ResultBeanView implements Serializable { private Result result = new Result(); /** Creates a new instance of ResultBeanView */ public ResultBeanView() { } @PostConstruct public void init() { // Try to find request bean ManagedBeanRequest and reset result value CalculatorBeanRequest calculatorBeanRequest = (CalculatorBeanRequest)FacesContext.getCurrentInstance().getExternalContext().getRequestMap().get("calculatorBeanRequest"); if(calculatorBeanRequest != null) { setResult(calculatorBeanRequest.getResult()); } } /** No need to have public modifier as not used on view * but only in managed bean within the same package */ void setResult(Result result) { this.result = result; } /** No need to have public modifier as not used on view * but only in managed bean within the same package */ Result getResult() { return result; } /** * To be called on page to instantiate ResultBeanView in Render view phase */ public boolean isDummy() { return false; } }

  • HLSL/XNA Ambient light texture mixed up with multi pass lighting

    - by Manu-EPITA
    I've been having some troubles lately with lighting. I have found a source on google which is working pretty good on the example. However, when I try to implement it to my current project, I am getting some very weird bugs. The main one is that my textures are "mixed up" when I only activate the ambient light, which means that a model gets the texture of another one . I am using the same effect for every meshes of my models. I guess this could be the problem, but I don't really know how to "reset" an effect for a new model. Is it possible? Here is my shader: float4x4 WVP; float4x4 WVP; float3x3 World; float3 Ke; float3 Ka; float3 Kd; float3 Ks; float specularPower; float3 globalAmbient; float3 lightColor; float3 eyePosition; float3 lightDirection; float3 lightPosition; float spotPower; texture2D Texture; sampler2D texSampler = sampler_state { Texture = <Texture>; MinFilter = anisotropic; MagFilter = anisotropic; MipFilter = linear; MaxAnisotropy = 16; }; struct VertexShaderInput { float4 Position : POSITION0; float2 Texture : TEXCOORD0; float3 Normal : NORMAL0; }; struct VertexShaderOutput { float4 Position : POSITION0; float2 Texture : TEXCOORD0; float3 PositionO: TEXCOORD1; float3 Normal : NORMAL0; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; output.Position = mul(input.Position, WVP); output.Normal = input.Normal; output.PositionO = input.Position.xyz; output.Texture = input.Texture; return output; } float4 PSAmbient(VertexShaderOutput input) : COLOR0 { return float4(Ka*globalAmbient + Ke,1) * tex2D(texSampler,input.Texture); } float4 PSDirectionalLight(VertexShaderOutput input) : COLOR0 { //Difuze float3 L = normalize(-lightDirection); float diffuseLight = max(dot(input.Normal,L), 0); float3 diffuse = Kd*lightColor*diffuseLight; //Specular float3 V = normalize(eyePosition - input.PositionO); float3 H = normalize(L + V); float specularLight = pow(max(dot(input.Normal,H),0),specularPower); if(diffuseLight<=0) specularLight=0; float3 specular = Ks * lightColor * specularLight; //sum all light components float3 light = diffuse + specular; return float4(light,1) * tex2D(texSampler,input.Texture); } technique MultiPassLight { pass Ambient { VertexShader = compile vs_3_0 VertexShaderFunction(); PixelShader = compile ps_3_0 PSAmbient(); } pass Directional { PixelShader = compile ps_3_0 PSDirectionalLight(); } } And here is how I actually apply my effects: public void ApplyLights(ModelMesh mesh, Matrix world, Texture2D modelTexture, Camera camera, Effect effect, GraphicsDevice graphicsDevice) { graphicsDevice.BlendState = BlendState.Opaque; effect.CurrentTechnique.Passes["Ambient"].Apply(); foreach (ModelMeshPart part in mesh.MeshParts) { graphicsDevice.SetVertexBuffer(part.VertexBuffer); graphicsDevice.Indices = part.IndexBuffer; // Texturing graphicsDevice.BlendState = BlendState.AlphaBlend; if (modelTexture != null) { effect.Parameters["Texture"].SetValue( modelTexture ); } graphicsDevice.DrawIndexedPrimitives( PrimitiveType.TriangleList, part.VertexOffset, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount ); // Applying our shader to all the mesh parts effect.Parameters["WVP"].SetValue( world * camera.View * camera.Projection ); effect.Parameters["World"].SetValue(world); effect.Parameters["eyePosition"].SetValue( camera.Position ); graphicsDevice.BlendState = BlendState.Additive; // Drawing lights foreach (DirectionalLight light in DirectionalLights) { effect.Parameters["lightColor"].SetValue(light.Color.ToVector3()); effect.Parameters["lightDirection"].SetValue(light.Direction); // Applying changes and drawing them effect.CurrentTechnique.Passes["Directional"].Apply(); graphicsDevice.DrawIndexedPrimitives( PrimitiveType.TriangleList, part.VertexOffset, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount ); } } I am also applying this when loading the effect: effect.Parameters["lightColor"].SetValue(Color.White.ToVector3()); effect.Parameters["globalAmbient"].SetValue(Color.White.ToVector3()); effect.Parameters["Ke"].SetValue(0.0f); effect.Parameters["Ka"].SetValue(0.01f); effect.Parameters["Kd"].SetValue(1.0f); effect.Parameters["Ks"].SetValue(0.3f); effect.Parameters["specularPower"].SetValue(100); Thank you very much UPDATE: I tried to load an effect for each model when drawing, but it doesn't seem to have changed anything. I suppose it is because XNA detects that the effect has already been loaded before and doesn't want to load a new one. Any idea why?

  • Does Microsoft hate firefox? ASP.Net gridview performance in firefox bug?

    - by Maxim Gershkovich
    Could someone please explain the significant difference in speed between a firefox updatepanel async postback and one performed in IE? Average Firefox Postback Time For 500 objects: 1.183 Second Average IE Postback Time For 500 objects: 0.295 Seconds Using firebug I can see that the majority of this time in FireFox is spent on the server side. A total of 1.04 seconds. Given this fact the only thing I can assume is causing this problem is the way that ASP.Net renders its controls between the two browsers.

  • Google App Engine - SiteMap Creation for a social network

    - by spidee
    Hi all. I am creating a social tool - I want to allow search engines to pick up "public" user profiles - like twitter and face-book. I have seen all the protocol info at http://www.sitemaps.org and i understand this and how to build such a file - along with an index if i exceed the 50K limit. Where i am struggling is the concept of how i make this run. The site map for my general site pages is simple i can use a tool to create the file - or a script - host the file - submit the file and done. What i then need is a script that will create the site-maps of user profiles. I assume this would be something like: <?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url> <loc>http://www.socialsite.com/profile/spidee</loc> <lastmod>2010-5-12</lastmod> <changefreq>???</changefreq> <priority>???</priority> </url> <url> <loc>http://www.socialsite.com/profile/webbsterisback</loc> <lastmod>2010-5-12</lastmod> <changefreq>???</changefreq> <priority>???</priority> </url> </urlset> Ive added some ??? as i don't know how i should set these settings for my profiles based on the following:- When a new profile is created it must be added to a site-map. If the profile is changed or if "certain" properties are changed - then i don't know if i update the entry in the map - or do something else? (updating would be a nightmare!) Some users may change their profile. In terms of relevance to the search engine the only way a google or yahoo search will find the users (for my requirement) profile would be for example by means of [user name] and [location] so once the entry for the profile has been added to the map file the only reason to have the search-bot re-index the profile would be if the user changed their user-name - which they cant. or their location - and or set their settings so that their profile would be "hidden" from search engines. I assume my map creation will need to be dynamic. From what i have said above i would imagine that creating a new profile and possible editing certain properties could mark it as needing adding/updating in the sitemap. Assuming i will have millions of profiles added/being edited how can i manage this in a sensible manner. i know i need a script that can append urls as each profile is created i know the script will prob be a TASK - running at a set freq - perhaps the profiles have a property like "indexed" and the TASK sets them to "true" when the profiles are added to the map. I dont see the best way to store the map - do i store it in the datastore i.e; model=sitemaps properties key_name=sitemap_xml_1 (and for my map sitemap_index_xml) mapxml=blobstore (the raw xml map or ror map) full=boolean (set true when url count is 50) # might need this as a shard will tell us To make this work my thoughts are m cache the current site map structure as "sitemap_xml" keep a shard of url count when my task executes 1. build the xml structure for say the first 100 urls marked "index==false" (how many could u run at a time?) 2. test if the current mcache sitemap is full (shardcounter+10050K) 3.a if the map is near full create a new map entry in models "sitemap_xml_2" - update the map_index file (also stored in my model as "sitemap_index" start a new shard - or reset.2 3.b if the map is not full grab it from mcache 4.append the 100 url xml structure 5.save / m cache the map I can now add a handler using a url map/route like /sitemaps/* Get my * as map name and serve the maps from the blobstore/mache on the fly. Now my question is does this work - is this the right way or a good way to start? Will this handle the situation of making sure the search bots update when a user changes their profile - possibly by setting the change freq correctly? - Do i need a more advance system :( ? or have i re-invented the wheel! I hope this is all clear and make some form of sense :-)

  • Different behavior for REF CURSOR between Oracle 10g and 11g when unique index present?

    - by wweicker
    Description I have an Oracle stored procedure that has been running for 7 or so years both locally on development instances and on multiple client test and production instances running Oracle 8, then 9, then 10, and recently 11. It has worked consistently until the upgrade to Oracle 11g. Basically, the procedure opens a reference cursor, updates a table then completes. In 10g the cursor will contain the expected results but in 11g the cursor will be empty. No DML or DDL changed after the upgrade to 11g. This behavior is consistent on every 10g or 11g instance I've tried (10.2.0.3, 10.2.0.4, 11.1.0.7, 11.2.0.1 - all running on Windows). The specific code is much more complicated but to explain the issue in somewhat realistic overview: I have some data in a header table and a bunch of child tables that will be output to PDF. The header table has a boolean (NUMBER(1) where 0 is false and 1 is true) column indicating whether that data has been processed yet. The view is limited to only show rows in that have not been processed (the view also joins on some other tables, makes some inline queries and function calls, etc). So at the time when the cursor is opened, the view shows one or more rows, then after the cursor is opened an update statement runs to flip the flag in the header table, a commit is issued, then the procedure completes. On 10g, the cursor opens, it contains the row, then the update statement flips the flag and running the procedure a second time would yield no data. On 11g, the cursor never contains the row, it's as if the cursor does not open until after the update statement runs. I'm concerned that something may have changed in 11g (hopefully a setting that can be configured) that might affect other procedures and other applications. What I'd like to know is whether anyone knows why the behavior is different between the two database versions and whether the issue can be resolved without code changes. Update 1: I managed to track the issue down to a unique constraint. It seems that when the unique constraint is present in 11g the issue is reproducible 100% of the time regardless of whether I'm running the real world code against the actual objects or the following simple example. Update 2: I was able to completely eliminate the view from the equation. I have updated the simple example to show the problem exists even when querying directly against the table. Simple Example CREATE TABLE tbl1 ( col1 VARCHAR2(10), col2 NUMBER(1) ); INSERT INTO tbl1 (col1, col2) VALUES ('TEST1', 0); /* View is no longer required to demonstrate the problem CREATE OR REPLACE VIEW vw1 (col1, col2) AS SELECT col1, col2 FROM tbl1 WHERE col2 = 0; */ CREATE OR REPLACE PACKAGE pkg1 AS TYPE refWEB_CURSOR IS REF CURSOR; PROCEDURE proc1 (crs OUT refWEB_CURSOR); END pkg1; CREATE OR REPLACE PACKAGE BODY pkg1 IS PROCEDURE proc1 (crs OUT refWEB_CURSOR) IS BEGIN OPEN crs FOR SELECT col1 FROM tbl1 WHERE col1 = 'TEST1' AND col2 = 0; UPDATE tbl1 SET col2 = 1 WHERE col1 = 'TEST1'; COMMIT; END proc1; END pkg1; Anonymous Block Demo DECLARE crs1 pkg1.refWEB_CURSOR; TYPE rectype1 IS RECORD ( col1 vw1.col1%TYPE ); rec1 rectype1; BEGIN pkg1.proc1 ( crs1 ); DBMS_OUTPUT.PUT_LINE('begin first test'); LOOP FETCH crs1 INTO rec1; EXIT WHEN crs1%NOTFOUND; DBMS_OUTPUT.PUT_LINE(rec1.col1); END LOOP; DBMS_OUTPUT.PUT_LINE('end first test'); END; /* After creating this index, the problem is seen */ CREATE UNIQUE INDEX unique_col1 ON tbl1 (col1); /* Reset data to initial values */ TRUNCATE TABLE tbl1; INSERT INTO tbl1 (col1, col2) VALUES ('TEST1', 0); DECLARE crs1 pkg1.refWEB_CURSOR; TYPE rectype1 IS RECORD ( col1 vw1.col1%TYPE ); rec1 rectype1; BEGIN pkg1.proc1 ( crs1 ); DBMS_OUTPUT.PUT_LINE('begin second test'); LOOP FETCH crs1 INTO rec1; EXIT WHEN crs1%NOTFOUND; DBMS_OUTPUT.PUT_LINE(rec1.col1); END LOOP; DBMS_OUTPUT.PUT_LINE('end second test'); END; Example of what the output on 10g would be:   begin first test   TEST1   end first test   begin second test   TEST1   end second test Example of what the output on 11g would be:   begin first test   TEST1   end first test   begin second test   end second test Clarification I can't remove the COMMIT because in the real world scenario the procedure is called from a web application. When the data provider on the front end calls the procedure it will issue an implicit COMMIT when disconnecting from the database anyways. So if I remove the COMMIT in the procedure then yes, the anonymous block demo would work but the real world scenario would not because the COMMIT would still happen. Question Why is 11g behaving differently? Is there anything I can do other than re-write the code?

  • Webkit browser jQuery transformations/transitions not working with jSplitSlider

    - by user3689793
    I am helping to build a site and i'm having an issue with the functionality of an add-in called jsplitslider when running it in chrome. Right now, when I navigate between the slides, the div's get stuck on top of each other and never clear the webkit transformations/animations: <div class="sl-content-slice" style="transition: all 800ms ease-in-out; -webkit-transition: all 800ms ease-in-out;"> I think the problem is due to timing of the functions, but I can't seem to figure out where I would need to add a setTimeout(). I only think this because I exhausted a lot of the other options like display: inline-block, notransitions css, etc. I'm desperate to figure out how to make this work in chrome. It works in FF and IE(surprisingly enough). I'm not great at webcoding, so any help will be appreciated! The code on the site isn't minimized. Here is the jQuery where I think the problem lies: var cssStyle = config.orientation === 'horizontal' ? { marginTop : -this.size.height / 2 } : { marginLeft : -this.size.width / 2 }, // default slide's slices style resetStyle = { 'transform' : 'translate(0%,0%) rotate(0deg) scale(1)', opacity : 1 }, // slice1 style slice1Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' } : { 'transform' : 'translateX(-' + this.options.translateFactor + '%) rotate(' + config.slice1angle + 'deg) scale(' + config.slice1scale + ')' }, // slice2 style slice2Style = config.orientation === 'horizontal' ? { 'transform' : 'translateY(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' } : { 'transform' : 'translateX(' + this.options.translateFactor + '%) rotate(' + config.slice2angle + 'deg) scale(' + config.slice2scale + ')' }; if( this.options.optOpacity ) { slice1Style.opacity = 0; slice2Style.opacity = 0; } // we are adding the classes sl-trans-elems and sl-trans-back-elems to the slide that is either coming "next" // or going "prev" according to the direction. // the idea is to make it more interesting by giving some animations to the respective slide's elements //( dir === 'next' ) ? $nextSlide.addClass( 'sl-trans-elems' ) : $currentSlide.addClass( 'sl-trans-back-elems' ); $currentSlide.removeClass( 'sl-trans-elems' ); var transitionProp = { 'transition' : 'all ' + this.options.speed + 'ms ease-in-out' }; // add the 2 slices and animate them $movingSlide.css( 'z-index', this.slidesCount ) .find( 'div.sl-content-wrapper' ) .wrap( $( '<div class="sl-content-slice" />' ).css( transitionProp ) ) .parent() .cond( dir === 'prev', function() { var slice = this; this.css( slice1Style ); setTimeout( function() { slice.css( resetStyle ); }, 150 ); }, function() { var slice = this; setTimeout( function() { slice.css( slice1Style ); }, 150 ); } ) .clone() .appendTo( $movingSlide ) .cond( dir === 'prev', function() { var slice = this; this.css( slice2Style ); setTimeout( function() { $currentSlide.addClass( 'sl-trans-back-elems' ); if( self.support ) { slice.css( resetStyle ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); }, function() { var slice = this; setTimeout( function() { $nextSlide.addClass( 'sl-trans-elems' ); if( self.support ) { slice.css( slice2Style ).on( self.transEndEventName, function() { self._onEndNavigate( slice, $currentSlide, dir ); } ); } else { self._onEndNavigate( slice, $currentSlide, dir ); } }, 150 ); } ) .find( 'div.sl-content-wrapper' ) .css( cssStyle ); $nextSlide.show(); }, _validateValues : function( config ) { // OK, so we are restricting the angles and scale values here. // This is to avoid the slices wrong sides to be shown. // you can adjust these values as you wish but make sure you also ajust the // paddings of the slides and also the options.translateFactor value and scale data attrs if( config.slice1angle > this.options.maxAngle || config.slice1angle < -this.options.maxAngle ) { config.slice1angle = this.options.maxAngle; } if( config.slice2angle > this.options.maxAngle || config.slice2angle < -this.options.maxAngle ) { config.slice2angle = this.options.maxAngle; } if( config.slice1scale > this.options.maxScale || config.slice1scale <= 0 ) { config.slice1scale = this.options.maxScale; } if( config.slice2scale > this.options.maxScale || config.slice2scale <= 0 ) { config.slice2scale = this.options.maxScale; } if( config.orientation !== 'vertical' && config.orientation !== 'horizontal' ) { config.orientation = 'horizontal' } }, _onEndNavigate : function( $slice, $oldSlide, dir ) { // reset previous slide's style after next slide is shown var $slide = $slice.parent(), removeClasses = 'sl-trans-elems sl-trans-back-elems'; // remove second slide's slice $slice.remove(); // unwrap.. $slide.css( 'z-index', 10 ) .find( 'div.sl-content-wrapper' ) .unwrap(); // hide previous current slide $oldSlide.hide().removeClass( removeClasses ); $slide.removeClass( removeClasses ); // now we can navigate again.. this.isAnimating = false; this.options.onAfterChange( $slide, this.current ); }, Sorry if I missed any conventions when posting, this is my first S.O. post. Thanks in advance for any help.

  • What is the best strategy for populating a TableView from a service?

    - by alrutherford
    I have an application which has a potentially long running background process. I want this process to populate a TableView as results objects are generated. The results objects are added to an observableList and have properties which are bound to the columns in the usual fashion for JavaFX. As an example of this consider the following sample code Main Application import java.util.LinkedList; import javafx.application.Application; import javafx.collections.FXCollections; import javafx.collections.ObservableList; import javafx.event.ActionEvent; import javafx.event.EventHandler; import javafx.geometry.Insets; import javafx.scene.Group; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.TableColumn; import javafx.scene.control.TableView; import javafx.scene.control.cell.PropertyValueFactory; import javafx.scene.layout.VBox; import javafx.stage.Stage; public class DataViewTest extends Application { private TableView<ServiceResult> dataTable = new TableView<ServiceResult>(); private ObservableList<ServiceResult> observableList; private ResultService resultService; public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) { observableList = FXCollections.observableArrayList(new LinkedList<ServiceResult>()); resultService = new ResultService(observableList); Button refreshBtn = new Button("Update"); refreshBtn.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent arg0) { observableList.clear(); resultService.reset(); resultService.start(); } }); TableColumn<ServiceResult, String> nameCol = new TableColumn<ServiceResult, String>("Value"); nameCol.setCellValueFactory(new PropertyValueFactory<ServiceResult, String>("value")); nameCol.setPrefWidth(200); dataTable.getColumns().setAll(nameCol); // productTable.getItems().addAll(products); dataTable.setItems(observableList); Scene scene = new Scene(new Group()); stage.setTitle("Table View Sample"); stage.setWidth(300); stage.setHeight(500); final VBox vbox = new VBox(); vbox.setSpacing(5); vbox.setPadding(new Insets(10, 0, 0, 10)); vbox.getChildren().addAll(refreshBtn, dataTable); ((Group) scene.getRoot()).getChildren().addAll(vbox); stage.setScene(scene); stage.show(); } } Service public class ResultService extends Service<Void> { public static final int ITEM_COUNT = 100; private ObservableList<ServiceResult> observableList; /** * Construct service. * */ public ResultService(ObservableList<ServiceResult> observableList) { this.observableList = observableList; } @Override protected Task<Void> createTask() { return new Task<Void>() { @Override protected Void call() throws Exception { process(); return null; } }; } public void process() { for (int i = 0; i < ITEM_COUNT; i++) { observableList.add(new ServiceResult(i)); } } } Data public class ServiceResult { private IntegerProperty valueProperty; /** * Construct property object. * */ public ServiceResult(int value) { valueProperty = new SimpleIntegerProperty(); setValue(value); } public int getValue() { return valueProperty.get(); } public void setValue(int value) { this.valueProperty.set(value); } public IntegerProperty valueProperty() { return valueProperty; } } Both the service and the TableView share a reference to the observable list? Is this good practise in JavaFx and if not what is the correct strategy? If you hit the the 'Update' button the list will not always refresh to the ITEM_COUNT length. I believe this is because the observableList.clear() is interfering with the update which is running in the background thread. Can anyone shed some light on this?

  • OpenGL true coordinates and glutTimerFunc() problem C++

    - by Meko
    HI I am starting to learn openGl for C++.but at stating point I stucked. I have 2 question that is the coordinates for drawing some objects? I mean where is X, Y and Z? Second one I am making tutorial from some sites. and I am trying to animate my triangle.In tutorial it works but on my computer not.I Also downloaded source codes but It doesnt move. Here sample codes. I thougt that problem is glutTimerFunc(). #include #include #ifdef APPLE #include #include #else #include #endif using namespace std; //Called when a key is pressed void handleKeypress(unsigned char key, int x, int y) { switch (key) { case 27: //Escape key exit(0); } } //Initializes 3D rendering void initRendering() { glEnable(GL_DEPTH_TEST); } //Called when the window is resized void handleResize(int w, int h) { glViewport(0, 0, w, h); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(45.0, (double)w / (double)h, 1.0, 200.0); } float _angle = 30.0f; float _cameraAngle = 0.0f; //Draws the 3D scene void drawScene() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glMatrixMode(GL_MODELVIEW); //Switch to the drawing perspective glLoadIdentity(); //Reset the drawing perspective glRotatef(-_cameraAngle, 0.0f, 1.0f, 0.0f); //Rotate the camera glTranslatef(0.0f, 0.0f, -5.0f); //Move forward 5 units glPushMatrix(); //Save the transformations performed thus far glTranslatef(0.0f, -1.0f, 0.0f); //Move to the center of the trapezoid glRotatef(_angle, 0.0f, 0.0f, 1.0f); //Rotate about the z-axis glBegin(GL_QUADS); //Trapezoid glVertex3f(-0.7f, -0.5f, 0.0f); glVertex3f(0.7f, -0.5f, 0.0f); glVertex3f(0.4f, 0.5f, 0.0f); glVertex3f(-0.4f, 0.5f, 0.0f); glEnd(); glPopMatrix(); //Undo the move to the center of the trapezoid glPushMatrix(); //Save the current state of transformations glTranslatef(1.0f, 1.0f, 0.0f); //Move to the center of the pentagon glRotatef(_angle, 0.0f, 1.0f, 0.0f); //Rotate about the y-axis glScalef(0.7f, 0.7f, 0.7f); //Scale by 0.7 in the x, y, and z directions glBegin(GL_TRIANGLES); //Pentagon glVertex3f(-0.5f, -0.5f, 0.0f); glVertex3f(0.5f, -0.5f, 0.0f); glVertex3f(-0.5f, 0.0f, 0.0f); glVertex3f(-0.5f, 0.0f, 0.0f); glVertex3f(0.5f, -0.5f, 0.0f); glVertex3f(0.5f, 0.0f, 0.0f); glVertex3f(-0.5f, 0.0f, 0.0f); glVertex3f(0.5f, 0.0f, 0.0f); glVertex3f(0.0f, 0.5f, 0.0f); glEnd(); glPopMatrix(); //Undo the move to the center of the pentagon glPushMatrix(); //Save the current state of transformations glTranslatef(-1.0f, 1.0f, 0.0f); //Move to the center of the triangle glRotatef(_angle, 1.0f, 2.0f, 3.0f); //Rotate about the the vector (1, 2, 3) glBegin(GL_TRIANGLES); //Triangle glVertex3f(0.5f, -0.5f, 0.0f); glVertex3f(0.0f, 0.5f, 0.0f); glVertex3f(-0.5f, -0.5f, 0.0f); glEnd(); glPopMatrix(); //Undo the move to the center of the triangle glutSwapBuffers(); } void update(int value) { _angle += 2.0f; if (_angle 360) { _angle -= 260; } glutPostRedisplay(); //Tell GLUT that the display has changed //Tell GLUT to call update again in 25 milliseconds glutTimerFunc(25, update, 0); } int main(int argc, char** argv) { //Initialize GLUT glutInit(&argc, argv); glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH); glutInitWindowSize(400, 400); //Create the window glutCreateWindow("Transformations and Timers - videotutorialsrock.com"); initRendering(); //Set handler functions glutDisplayFunc(drawScene); glutKeyboardFunc(handleKeypress); glutReshapeFunc(handleResize); glutTimerFunc(24, update, 0); //Add a timer glutMainLoop(); return 0; }

  • Preventing FIN_WAIT2 when closing socket

    - by patrickvacek
    I have a server program that connects to another program via a given socket, and in certain cases I need to close the connection and almost immediately re-open it on the same socket. This by and large works, except that I have to wait exactly one minute for the socket to reset. In the meantime, netstat indicates that the server sees the socket in FIN_WAIT2 and the client sees it as CLOSE_WAIT. I'm already using SO_REUSEADDR, which I thought would prevent the wait, but that isn't doing the trick. Setting SO_LINGER to zero also does not help. What else can I do to resolve this? Here are the relevant code snippets: SetUpSocket() { // Set up the socket and listen for a connection from the exelerate client. // Open a TCP/IP socket. m_baseSock = socket(PF_INET, SOCK_STREAM, IPPROTO_IP); if (m_baseSock < 0) { return XERROR; } // Set the socket options to reuse local addresses. int flag = 1; if (setsockopt(m_baseSock, SOL_SOCKET, SO_REUSEADDR, &flag, sizeof(flag)) == -1) { return XERROR; } // Set the socket options to prevent lingering after closing the socket. //~ linger li = {1,0}; //~ if (setsockopt(m_baseSock, SOL_SOCKET, SO_LINGER, &li, sizeof(li)) == -1) //~ { //~ return XERROR; //~ } // Bind the socket to the address of the current host and our given port. struct sockaddr_in addr; memset(&addr, 0, sizeof(addr)); addr.sin_family = AF_INET; addr.sin_addr.s_addr = INADDR_ANY; addr.sin_port = htons(m_port); if (bind(m_baseSock, (struct sockaddr*)&addr, sizeof(addr)) != 0) { return XERROR; } // Tell the socket to listen for a connection from client. if (listen(m_baseSock, 4) != 0) { return XERROR; } return XSUCCESS; } ConnectSocket() { // Add the socket to a file descriptor set. fd_set readfds; FD_ZERO(&readfds); FD_SET(m_baseSock, &readfds); // Set timeout to ten seconds. Plenty of time. struct timeval timeout; timeout.tv_sec = 10; timeout.tv_usec = 0; // Check to see if the socket is ready for reading. int numReady = select(m_baseSock + 1, &readfds, NULL, NULL, &timeout); if (numReady > 0) { int flags = fcntl(m_baseSock, F_GETFL, 0); fcntl(m_baseSock, flags | O_NONBLOCK, 1); // Wait for a connection attempt from the client. Do not block - we shouldn't // need to since we just selected. m_connectedSock = accept(m_baseSock, NULL, NULL); if (m_connectedSock > 0) { m_failedSend = false; m_logout = false; // Spawn a thread to accept commands from client. CreateThread(&m_controlThread, ControlThread, (void *)&m_connectedSock); return XSUCCESS; } } return XERROR; } ControlThread(void *arg) { // Get the socket from the argument. socket sock = *((socket*)arg); while (true) { // Add the socket to a file descriptor set. fd_set readfds; FD_ZERO(&readfds); FD_SET(sock, &readfds); // Set timeout to ten seconds. Plenty of time. struct timeval timeout; timeout.tv_sec = 10; timeout.tv_usec = 0; // Check if there is any readable data on the socket. int num_ready = select(sock + 1, &readfds, NULL, NULL, &timeout); if (num_ready < 0) { return NULL; } // If there is data, read it. else if (num_ready > 0) { // Check the read buffer. xuint8 buf[128]; ssize_t size_read = recv(sock, buf, sizeof(buf)); if (size_read > 0) { // Get the message out of the buffer. char msg = *buf; if (msg == CONNECTED) { // Do some things... } // If we get the log-out message, log out. else if (msg == LOGOUT) { return NULL; } } } } // while return NULL; } ~Server() { // Close the sockets. if (m_baseSock != SOCKET_ERROR) { close(m_baseSock); m_baseSock = SOCKET_ERROR; } if (m_connectedSock != SOCKET_ERROR) { close(m_connectedSock); m_connectedSock = SOCKET_ERROR; } } SOCKET_ERROR is equal to -1. The server object gets destroyed, at which point the connection should close, and then recreated, at which point the SetUpSocket() and ConnectSocket() routines are called. So why do I have to wait a minute for the socket to clear? Any ideas would be appreaciated.

  • OpenGL texture shifted somewhat to the left when applied to a quad

    - by user308226
    I'm a bit new to OpenGL and I've been having a problem with using textures. The texture seems to load fine, but when I run the program, the texture displays shifted a couple pixels to the left, with the section cut off by the shift appearing on the right side. I don't know if the problem here is in the my TGA loader or if it's the way I'm applying the texture to the quad. Here is the loader: #include "texture.h" #include <iostream> GLubyte uncompressedheader[12] = {0,0, 2,0,0,0,0,0,0,0,0,0}; GLubyte compressedheader[12] = {0,0,10,0,0,0,0,0,0,0,0,0}; TGA::TGA() { } //Private loading function called by LoadTGA. Loads uncompressed TGA files //Returns: TRUE on success, FALSE on failure bool TGA::LoadCompressedTGA(char *filename,ifstream &texturestream) { return false; } bool TGA::LoadUncompressedTGA(char *filename,ifstream &texturestream) { cout << "G position status:" << texturestream.tellg() << endl; texturestream.read((char*)header, sizeof(header)); //read 6 bytes into the file to get the tga header width = (GLuint)header[1] * 256 + (GLuint)header[0]; //read and calculate width and save height = (GLuint)header[3] * 256 + (GLuint)header[2]; //read and calculate height and save bpp = (GLuint)header[4]; //read bpp and save cout << bpp << endl; if((width <= 0) || (height <= 0) || ((bpp != 24) && (bpp !=32))) //check to make sure the height, width, and bpp are valid { return false; } if(bpp == 24) { type = GL_RGB; } else { type = GL_RGBA; } imagesize = ((bpp/8) * width * height); //determine size in bytes of the image cout << imagesize << endl; imagedata = new GLubyte[imagesize]; //allocate memory for our imagedata variable texturestream.read((char*)imagedata,imagesize); //read according the the size of the image and save into imagedata for(GLuint cswap = 0; cswap < (GLuint)imagesize; cswap += (bpp/8)) //loop through and reverse the tga's BGR format to RGB { imagedata[cswap] ^= imagedata[cswap+2] ^= //1st Byte XOR 3rd Byte XOR 1st Byte XOR 3rd Byte imagedata[cswap] ^= imagedata[cswap+2]; } texturestream.close(); //close ifstream because we're done with it cout << "image loaded" << endl; glGenTextures(1, &texID); // Generate OpenGL texture IDs glBindTexture(GL_TEXTURE_2D, texID); // Bind Our Texture glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); // Linear Filtered glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, type, width, height, 0, type, GL_UNSIGNED_BYTE, imagedata); delete imagedata; return true; } //Public loading function for TGA images.

  • Redrawing content of UIWebView

    - by btate
    I have a bunch of webviews with static html content that I'm putting in a scroll view as pages. That works fine, but having 20 something full screen subviews of the scroll view is causing some lag. I solved that by only placing 5 at a time in there. The current view, and the two next and two previous. The problem now is that any web view that is not a subview of the scroll view is not drawing correctly based on the device orientation. The frame of the webview is printing out correct, but the actual content is drawing in portrait mode. So there is essentially a strip of blank space to the right of the content. How do I go about re rendering the content without reloading the page? Here's the relevant code: - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation) fromInterfaceOrientation{ [self resizeSubViews]; } - (void) setupWebViews{ if(_webViews == nil) _webViews = [[NSMutableArray alloc] init]; // This is where the navigation would come into play as far as loading up available web views [_webViews removeAllObjects]; // for loop here to create web views for (int i = 0; i < 20; i++) { //CDCWebViewController *webView = [[[MyInternalWebView alloc] initWithFrame:_webViewWrapper.frame] retain]; MyInternalWebView *page = [[[MyInternalWebView alloc] init] retain]; [page loadRequest:[NSURLRequest requestWithURL:_url]]; [page setCdcIWVdelegate:self]; [page setTestIndex:i]; [page setPageIndex:i]; [_webViews addObject:page]; [self loadScrollViewWithPage:i]; } [self clearUnusedWebViews:_pageControl.currentPage]; } - (void) setupWebViewWrapper{ // a page is the width of the scroll view _webViewWrapper.pagingEnabled = YES; _pageControl = [[[UIPageControl alloc] init] retain]; _webViewWrapper.showsHorizontalScrollIndicator = NO; _webViewWrapper.showsVerticalScrollIndicator = NO; _webViewWrapper.scrollsToTop = NO; _webViewWrapper.delegate = self; _pageControl.numberOfPages = [_webViews count]; _pageControl.currentPage = 0; } - (void) resizeSubViews{ // The frame is set in IB _webViewWrapper.contentSize = CGSizeMake(_webViewWrapper.frame.size.width * [_webViews count], _webViewWrapper.frame.size.height); // Move the content offset. _webViewWrapper.contentOffset = CGPointMake(_webViewWrapper.frame.size.width * _pageControl.currentPage, _webViewWrapper.contentOffset.y); for (MyInternalWebView *subview in _webViewWrapper.subviews) { // Reset the frame height and width here? CGRect frame = _webViewWrapper.frame; frame.origin.x = frame.size.width * subview.pageIndex; frame.origin.y = 0; [subview setFrame:frame]; } } //***************************************************** //* //* ScrollView Functions //* //***************************************************** - (void)loadScrollViewWithPage:(int)page { // Make sure we're not out of bounds if (page < 0) return; if (page >= [_webViews count]) return; MyInternalWebView *webView = [_webViews objectAtIndex:page]; // Add the preloaded webview to the scrollview if it's not there already if (nil == [webView superview]) { CGRect frame = _webViewWrapper.frame; //NSLog(@"width = %f", frame.size.width); frame.origin.x = frame.size.width * page; frame.origin.y = 0; //NSLog(@"setting frame for page %d %@", page, NSStringFromCGRect(frame)); [webView setFrame:frame]; [_webViewWrapper addSubview:[_webViews objectAtIndex:page]]; // Now that the new one is loaded, clear what doesn't need to be here [self clearUnusedWebViews:page]; } } - (void) clearUnusedWebViews: (NSInteger) page{ for (int i = 0; i < [_webViews count]; i++) { if ((page - i) <= 2 && i - page <= 2) { continue; } [[_webViews objectAtIndex:i] removeFromSuperview]; } } - (void)scrollViewDidScroll:(UIScrollView *)sender { // Switch the indicator when more than 50% of the previous/next page is visible CGFloat pageWidth = _webViewWrapper.frame.size.width; NSInteger page = floor((_webViewWrapper.contentOffset.x - pageWidth / 2) / pageWidth) + 1; _pageControl.currentPage = page; // load the visible page and the page on either side of it (to avoid flashes when the user starts scrolling) [self loadScrollViewWithPage:page - 2]; [self loadScrollViewWithPage:page - 1]; [self loadScrollViewWithPage:page]; [self loadScrollViewWithPage:page + 1]; [self loadScrollViewWithPage:page + 2]; }

  • files get uploaded just before they get cancelled

    - by user1763986
    Got a little situation here where I am trying to cancel a file's upload. What I have done is stated that if the user clicks on the "Cancel" button, then it will simply remove the iframe so that it does not go to the page where it uploads the files into the server and inserts data into the database. Now this works fine if the user clicks on the "Cancel" button in quickish time the problem I have realised though is that if the user clicks on the "Cancel" button very late, it sometimes doesn't remove the iframe in time meaning that the file has just been uploaded just before the user has clicked on the "Cancel" button. So my question is that is there a way that if the file does somehow get uploaded before the user clicks on the "Cancel" button, that it deletes the data in the database and removes the file from the server? Below is the image upload form: <form action="imageupload.php" method="post" enctype="multipart/form-data" target="upload_target_image" onsubmit="return imageClickHandler(this);" class="imageuploadform" > <p class="imagef1_upload_process" align="center"> Loading...<br/> <img src="Images/loader.gif" /> </p> <p class="imagef1_upload_form" align="center"> <br/> <span class="imagemsg"></span> <label>Image File: <input name="fileImage" type="file" class="fileImage" /></label><br/> <br/> <label class="imagelbl"><input type="submit" name="submitImageBtn" class="sbtnimage" value="Upload" /></label> </p> <p class="imagef1_cancel" align="center"> <input type="reset" name="imageCancel" class="imageCancel" value="Cancel" /> </p> <iframe class="upload_target_image" name="upload_target_image" src="#" style="width:0px;height:0px;border:0px;solid;#fff;"></iframe> </form> Below is the jquery function which controls the "Cancel" button: $(imageuploadform).find(".imageCancel").on("click", function(event) { $('.upload_target_image').get(0).contentwindow $("iframe[name='upload_target_image']").attr("src", "javascript:'<html></html>'"); return stopImageUpload(2); }); Below is the php code where it uploads the files and inserts the data into the database. The form above posts to this php page "imageupload.php": <body> <?php include('connect.php'); session_start(); $result = 0; //uploads file move_uploaded_file($_FILES["fileImage"]["tmp_name"], "ImageFiles/" . $_FILES["fileImage"]["name"]); $result = 1; //set up the INSERT SQL query command to insert the name of the image file into the "Image" Table $imagesql = "INSERT INTO Image (ImageFile) VALUES (?)"; //prepare the above SQL statement if (!$insert = $mysqli->prepare($imagesql)) { // Handle errors with prepare operation here } //bind the parameters (these are the values that will be inserted) $insert->bind_param("s",$img); //Assign the variable of the name of the file uploaded $img = 'ImageFiles/'.$_FILES['fileImage']['name']; //execute INSERT query $insert->execute(); if ($insert->errno) { // Handle query error here } //close INSERT query $insert->close(); //Retrieve the ImageId of the last uploded file $lastID = $mysqli->insert_id; //Insert into Image_Question Table (be using last retrieved Image id in order to do this) $imagequestionsql = "INSERT INTO Image_Question (ImageId, SessionId, QuestionId) VALUES (?, ?, ?)"; //prepare the above SQL statement if (!$insertimagequestion = $mysqli->prepare($imagequestionsql)) { // Handle errors with prepare operation here echo "Prepare statement err imagequestion"; } //Retrieve the question number $qnum = (int)$_POST['numimage']; //bind the parameters (these are the values that will be inserted) $insertimagequestion->bind_param("isi",$lastID, 'Exam', $qnum); //execute INSERT query $insertimagequestion->execute(); if ($insertimagequestion->errno) { // Handle query error here } //close INSERT query $insertimagequestion->close(); ?> <!--Javascript which will output the message depending on the status of the upload (successful, failed or cancelled)--> <script> window.top.stopImageUpload(<?php echo $result; ?>, '<?php echo $_FILES['fileImage']['name'] ?>'); </script> </body> UPDATE: Below is the php code "cancelimage.php" where I want to delete the cancelled file from the server and delete the record from the database. It is set up but not finished, can somebody finish it off so I can retrieve the name of the file and it's id using $_SESSION? <?php // connect to the database include('connect.php'); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); die(); } //remove file from server unlink("ImageFiles/...."); //need to retrieve file name here where the ... line is //DELETE query statement where it will delete cancelled file from both Image and Image Question Table $imagedeletesql = " DELETE img, img_q FROM Image AS img LEFT JOIN Image_Question AS img_q ON img_q.ImageId = img.ImageId WHERE img.ImageFile = ?"; //prepare delete query if (!$delete = $mysqli->prepare($imagedeletesql)) { // Handle errors with prepare operation here } //Dont pass data directly to bind_param store it in a variable $delete->bind_param("s",$img); //execute DELETE query $delete->execute(); if ($delete->errno) { // Handle query error here } //close query $delete->close(); ?> Can you please provide an sample code in your answer to make it easier for me. Thank you
