  • How to convert ISampleGrabber::BufferCB's buffer to a bitmap

    - by user2509919
    I am trying to use the ISampleGrabberCB::BufferCB to convert the current frame to bitmap using the following code: int ISampleGrabberCB.BufferCB(double sampleTime, IntPtr buffer, int bufferLength) { try { Form1 form1 = new Form1("", "", ""); if (pictureReady == null) { Debug.Assert(bufferLength == Math.Abs(pitch) * videoHeight, "Wrong Buffer Length"); } Debug.Assert(imageBuffer != IntPtr.Zero, "Remove Buffer"); Bitmap bitmapOfCurrentFrame = new Bitmap(width, height, capturePitch, PixelFormat.Format24bppRgb, buffer); MessageBox.Show("Works"); form1.changepicturebox3(bitmapOfCurrentFrame); pictureReady.Set(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } return 0; } However this does not seem to be working. Additionally it seems to call this function when i press a button which runs the following code: public IntPtr getFrame() { int hr; try { pictureReady.Reset(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } imageBuffer = Marshal.AllocCoTaskMem(Math.Abs(pitch) * videoHeight); try { gotFrame = true; if (videoControl != null) { hr = videoControl.SetMode(stillPin, VideoControlFlags.Trigger); DsError.ThrowExceptionForHR(hr); } if (!pictureReady.WaitOne(9000, false)) { throw new Exception("Timeout waiting to get picture"); } } catch { Marshal.FreeCoTaskMem(imageBuffer); imageBuffer = IntPtr.Zero; } return imageBuffer; } Once this code is ran I get a message box which shows 'Works' thus meaning my BufferCB must of been called however does not update my picture box with the current image. Is the BufferCB not called after every new frame? If so why do I not recieve the 'Works' message box? Finally is it possible to convert every new frame into a bitmap (this is used for later processing) using BufferCB and if so how? Edited code: int ISampleGrabberCB.BufferCB(double sampleTime, IntPtr buffer, int bufferLength) { Debug.Assert(bufferLength == Math.Abs(pitch) * videoHeight, "Wrong Buffer Length"); Debug.Assert(imageBuffer != IntPtr.Zero, "Remove Buffer"); CopyMemory(imageBuffer, buffer, bufferLength); Decode(buffer); return 0; } public Image Decode(IntPtr imageData) { var bitmap = new Bitmap(width, height, pitch, PixelFormat.Format24bppRgb, imageBuffer); bitmap.RotateFlip(RotateFlipType.RotateNoneFlipY); Form1 form1 = new Form1("", "", ""); form1.changepicturebox3(bitmap); bitmap.Save("C:\\Users\\...\\Desktop\\A2 Project\\barcode.jpg"); return bitmap; } Button code: public void getFrameFromWebcam() { if (iPtr != IntPtr.Zero) { Marshal.FreeCoTaskMem(iPtr); iPtr = IntPtr.Zero; } //Get Image iPtr = sampleGrabberCallBack.getFrame(); Bitmap bitmapOfFrame = new Bitmap(sampleGrabberCallBack.width, sampleGrabberCallBack.height, sampleGrabberCallBack.capturePitch, PixelFormat.Format24bppRgb, iPtr); bitmapOfFrame.RotateFlip(RotateFlipType.RotateNoneFlipY); barcodeReader(bitmapOfFrame); } public IntPtr getFrame() { int hr; try { pictureReady.Reset(); } catch (Exception ex) { MessageBox.Show(ex.ToString()); } imageBuffer = Marshal.AllocCoTaskMem(Math.Abs(pitch) * videoHeight); try { gotFrame = true; if (videoControl != null) { hr = videoControl.SetMode(stillPin, VideoControlFlags.Trigger); DsError.ThrowExceptionForHR(hr); } if (!pictureReady.WaitOne(9000, false)) { throw new Exception("Timeout waiting to get picture"); } } catch { Marshal.FreeCoTaskMem(imageBuffer); imageBuffer = IntPtr.Zero; } return imageBuffer; } I also still need to press the button to run the BufferCB Thanks for reading.

  • Routing generated paths in Ruby on Rails

    - by True Soft
    I'm a beginner in ruby-on-rails and I spent my last hour trying to do the following thing: I have a ruby-on-rails application - the blog with posts and categories. I want to have another URL for the posts (I would like to have http://localhost:3000/news instead of http://localhost:3000/posts) First I tried to replace the controller and classes from Posts to News, but I gave up(because of the annoyng singular-plural thing). Then in my I replaced map.resources :posts (case 1) to map.resources :news, :controller => "posts" #case 2 or map.resources :posts, :as => 'news' #case 3 in routes.rb as I saw on some websites. It doesn't work either. How can I do this? EDIT: the output of rake routes is (only first lines): for case 1 and 3: posts GET /posts {:action=>"index", :controller=>"posts"} formatted_posts GET /posts.:format {:action=>"index", :controller=>"posts"} POST /posts {:action=>"create", :controller=>"posts"} POST /posts.:format {:action=>"create", :controller=>"posts"} new_post GET /posts/new {:action=>"new", :controller=>"posts"} formatted_new_post GET /posts/new.:format {:action=>"new", :controller=>"posts"} edit_post GET /posts/:id/edit {:action=>"edit", :controller=>"posts"} formatted_edit_post GET /posts/:id/edit.:format {:action=>"edit", :controller=>"posts"} post GET /posts/:id {:action=>"show", :controller=>"posts"} formatted_post GET /posts/:id.:format {:action=>"show", :controller=>"posts"} PUT /posts/:id {:action=>"update", :controller=>"posts"} PUT /posts/:id.:format {:action=>"update", :controller=>"posts"} DELETE /posts/:id {:action=>"destroy", :controller=>"posts"} DELETE /posts/:id.:format {:action=>"destroy", :controller=>"posts"} the output for case 2: news_index GET /news {:action=>"index", :controller=>"posts"} formatted_news_index GET /news.:format {:action=>"index", :controller=>"posts"} POST /news {:action=>"create", :controller=>"posts"} POST /news.:format {:action=>"create", :controller=>"posts"} new_news GET /news/new {:action=>"new", :controller=>"posts"} formatted_new_news GET /news/new.:format {:action=>"new", :controller=>"posts"} edit_news GET /news/:id/edit {:action=>"edit", :controller=>"posts"} formatted_edit_news GET /news/:id/edit.:format {:action=>"edit", :controller=>"posts"} news GET /news/:id {:action=>"show", :controller=>"posts"} formatted_news GET /news/:id.:format {:action=>"show", :controller=>"posts"} PUT /news/:id {:action=>"update", :controller=>"posts"} PUT /news/:id.:format {:action=>"update", :controller=>"posts"} DELETE /news/:id {:action=>"destroy", :controller=>"posts"} DELETE /news/:id.:format {:action=>"destroy", :controller=>"posts"} I have errors in case 2, because in my sourcecode I don't have edit_news, I have for example <%= link_to 'Edit', edit_post_path(post) %>

  • showing the breadcrumb trail in the menu

    - by strangeloops
    I have a global menu and local menu for the products. I would like to highlight 'our products' link when I am showing the products and also highlight the name of the product and its subpages in the local menu so the highlighted links will work as the breadcrumbs. How can I do this with jquery and codeigniter or just jquery. Here is the code of the local menu: <ul id="accordion"> <li class="pm"><h2><?php echo anchor('/products/thassos_wonder', 'Thassos Wonder+');?></h2> <ul class="product_menu"> <h2><?php echo anchor('/products/thassos_wonder', 'Thassos Wonder+');?></h2> <h2><?php echo anchor('/products/thassos_wonder_advantages', 'Thassos Wonder+ Advantages');?></h2> <h2><?php echo anchor('products/thassos_wonder_associated_products', 'Associated Products');?></h2> <h2><?php echo anchor('/products/thassos_wonder_brochure', 'Download TW+ Brochure');?></h2> </ul> </li> <li class="pm"><h2><?php echo anchor('/products/marble_wonder', 'Marble Wonder+');?></h2> <ul class="product_menu" id="mwmenu"> <h2><?php echo anchor('/products/marble_wonder', 'Marble Wonder+');?></h2> <h2><?php echo anchor('/products/marble_wonder_advantages', 'Marble Wonder+ Advantages');?></h2> <h2><?php echo anchor('products/marble_wonder_associated_products', 'Associated Products');?></h2> <h2><?php echo anchor('/products/marble_wonder_brochure', 'Download MW+ Brochure');?></h2> </ul> </li> <li class="pm"><h2><?php echo anchor('/products/polybond', 'Poly Bond+');?></h2> <ul class="product_menu" id="pbmenu"> <h2><?php echo anchor('/products/polybond', 'Poly Bond+');?></h2> <h2><?php echo anchor('/products/polybond_advantages', 'PolyBond+ Advantages');?></h2> <h2><?php echo anchor('products/polybond_areas_of_applications', 'Areas of Applications');?></h2> <h2><?php echo anchor('/products/polybond_brochure', 'Download Polybond+ Brochure');?></h2> </ul> </li> Here is the jquery code for the local menu: $(function() { var pathname = location.pathname; var highlight; //highlight home if(pathname == "/"){ highlight = $('ul#accordion > li:first > a:first'); $('a.active').parents('li').addClass('active'); } else { var path = pathname.substring(1); if (path) highlight = $('ul#accordion a[href$="' + path + '"]'); } highlight.attr('class', 'active'); // hide 2nd, 3rd, ... level menus $('ul#accordion ul').hide(); // show child menu on click $('ul#accordion > li > a.product_menu').click(function() { //minor improvement $(this).siblings('ul').toggle("slow"); return false; }); //open to current group (highlighted link) by show all parent ul's $('a.active').parents('ul').show(); //if you only have a 2 level deep navigation you could //use this instead //$('a.selected').parents("ul").eq(0).show(); }); Still learning jquery so type of help would be appreciated.

  • rails: "unknown action" message when action is clearly specified

    - by john
    hi, I had hard time to figure out why I've been getting "unknown action" error message when I was do some editing: Unknown action No action responded to 11. Actions: bin, create, destroy, edit, index, new, observe_new, show, tag, update, and vote you can see that Rails did mention each action in the above list - update. And in my form, I did specify action = "update". I wonder if some friends could kindly help me with the missing links... here is the code: edit.rhtml <h1>Editing tip</h1> <% form_tag :action => 'update', :id => @tip do %> <%= render :partial => 'form' %> <p> <%= submit_tag_or_cancel 'Save Changes' %> </p> <% end %> _form.rhtml <%= error_messages_for :tip %> <p><label>Title<br/> <%= text_field :tip, :title %></label></p> <p><label>Categories<br/> <%= select_tag('categories[]', options_for_select(Category.find(:all).collect {|c| [c.name, c.id] }, @tip.category_ids), :multiple => true ) %></label></p> <p><label>Abstract:<br/> <%= text_field_with_auto_complete :tip, :abstract %></label></p> <p><label>Name: <br/> <%= text_field :tip, :name %></label></p> <p><label>Link: <br/> <%= text_field :tip, :link %></label></p> <p><label>Content<br/> <%= text_area :tip, :content, :rows => 5 %></label></p> <p><label>Tags <span>(space separated)</span><br/> <%= text_field_tag 'tags', @tip.tag_list, :size => 40 %></label></p> class TipsController < ApplicationController before_filter :authenticate, :except => %w(index show) # GET /tips # GET /tips.xml def index @tips = Tip.all respond_to do |format| format.html # index.html.erb format.xml { render :xml => @tips } end end # GET /tips/1 # GET /tips/1.xml def show @tip = Tip.find_by_permalink(params[:permalink]) respond_to do |format| format.html # show.html.erb format.xml { render :xml => @tip } end end # GET /tips/new # GET /tips/new.xml def new @tip = session[:tip_draft] || current_user.tips.build end def create #tip = current_user.tips.build(params[:tip]) #tipMail=params[:email] #if tipMail # TipMailer.deliver_email_friend(params[:email], params[:name], tip) # flash[:notice] = 'Your friend has been notified about this tip' #end @tip = current_user.tips.build(params[:tip]) @tip.categories << Category.find(params[:categories]) unless params[:categories].blank? @tip.tag_with(params[:tags]) if params[:tags] if @tip.save flash[:notice] = 'Tip was successfully created.' session[:tip_draft] = nil redirect_to :action => 'index' else render :action => 'new' end end def edit @tip = Tip.find(params[:id]) end def update @tip = Tip.find(params[:id]) respond_to do |format| if @tip.update_attributes(params[:tip]) flash[:notice] = 'Tip was successfully updated.' format.html { redirect_to(@tip) } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @tip.errors, :status => :unprocessable_entity } end end end def destroy @tip = Tip.find(params[:id]) @tip.destroy respond_to do |format| format.html { redirect_to(tips_url) } format.xml { head :ok } end end def observe_new session[:tip_draft] = current_user.tips.build(params[:tip]) render :nothing => true end end

  • JS: using 'var me = this' to reference an object instead of using a global array

    - by Marco Demaio
    The example below, is just an example, I know that I don't need an object to show an alert box when user clicks on div blocks, but it's just a simple example to explain a situation that frequently happens when writing JS code. In the example below I use a globally visible array of objects to keep a reference to each new created HelloObject, in this way events called when clicking on a div block can use the reference in the arry to call the HelloObject's public function hello(). 1st have a look at the code: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head><meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title>Test </title> <script type="text/javascript"> /***************************************************** Just a cross browser append event function, don't need to understand this one to answer my question *****************************************************/ function AppendEvent(html_element, event_name, event_function) {if(html_element) {if(html_element.attachEvent) html_element.attachEvent("on" + event_name, event_function); else if(html_element.addEventListener) html_element.addEventListener(event_name, event_function, false); }} /****************************************************** Just a test object ******************************************************/ var helloobjs = []; var HelloObject = function HelloObject(div_container) { //Adding this object in helloobjs array var id = helloobjs.length; helloobjs[id] = this; //Appending click event to show the hello window AppendEvent(div_container, 'click', function() { helloobjs[id].hello(); //THIS WORKS! }); /***************************************************/ this.hello = function() { alert('hello'); } } </script> </head><body> <div id="one">click me</div> <div id="two">click me</div> <script type="text/javascript"> var t = new HelloObject(document.getElementById('one')); var t = new HelloObject(document.getElementById('two')); </script> </body></html> In order to achive the same result I could simply replace the code //Appending click event to show the hello window AppendEvent(div_container, 'click', function() { helloobjs[id].hello(); //THIS WORKS! }); with this code: //Appending click event to show the hello window var me = this; AppendEvent(div_container, 'click', function() { me.hello(); //THIS WORKS TOO AND THE GLOBAL helloobjs ARRAY BECOMES SUPEFLOUS! }); thus would make the helloobjs array superflous. My question is: does this 2nd option in your opinion create memoy leaks on IE or strange cicular references that might lead to browsers going slow or to break??? I don't know how to explain, but coming from a background as a C/C++ coder, doing in this 2nd way sounds like a some sort of circular reference that might break memory at some point. I also read on internet about the IE closures memory leak issue http://jibbering.com/faq/faq_notes/closures.html (I don't know if it was fixed in IE7 and if yes, I hope it does not come out again in IE8). Thanks

  • Which option do you like the most?

    - by spderosso
    I need to show a list of movies ordered by the date they were registered in the system and the amount of comments users have made about them. E.g: Title | Register Date | # of comments Gladiator | 02-01-2010 | 30 Matrix | 01-02-2010 | 20 It is a web application that follows MVC. So, I have the object "Movie", there is a MovieManager interface that is used for retrieving/persisting data to the database and a servlet RecentlyAddedMovies.java that forwards to a .jsp to render the list. I will explain my problem by showing an example of how I am doing another similar task: Showing top ranked movies. Regarding the MovieManager: /** * Returns a collection of the x best-ranked movies * @param x the amount of movies to return * @return A collection of movies * @throws SQLException */ public Collection<Movie> getTopX(int x) throws SQLException; The servlet: public class Top5 extends HttpServlet{ @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { MovieManager movManager = JDBCMovieManager.getInstance(); try { req.setAttribute("movies", movManager.getTopX(5)); } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace(); } req.getRequestDispatcher("listMovies.jsp").forward(req, resp); } } And the listMovies.jsp has is some place something like: <c:forEach var="movie" items="${movies}"> ... <c:out value="${movie.title}"/> ... </c:forEach> The difference between the top5 problem and the problem I am trying to solve is that with the top5 thing all the data I needed to show in the view where part of the "Movie" object, so the MovieManager simply returned a Collection of Movies. Now, the MovieManager must retrieve an ordered list of (Movie, # of comments). The Movie object has a collection of Comment associated but of course, it lacks an instance variable with the length of that collection. The following things came into my mind: a) Create a MovieView object or something like that, that is only used by the "View" and "Controller" layer of the MVC which is not part of the "Model" in the sense that is used only for easy retrieval and display of information. This MovieView object will have a title, registerDate and # of Comments so the thing would look something like this: /** * Returns a collection of the x most recently added movies * @param x the amount of movies to return * @return A collection of movies * @throws SQLException */ public Collection<Movie2> getXRecentlyAddedMovies(int x) throws SQLException; The .jsp: <c:forEach var="movie2" items="${movies2}"> ... <c:out value="${movie2.title}"/> <c:out value="${movie2.registerDate}"/> <c:out value="${movie2.noOfComments}"/> ... </c:forEach> b) Add to the Collection the movie has, empty Comments (there is no actual need to retrieve all the comment data from the database) so that the comment's collection.size() will show the number of comments that movie has. (This sounds horrible to me) c) Add to the "Movie" object an instance field noOfComments with the setter and getter that will help with this type of cases even if, looking only from the object point of view, it is a redundant field since it already has a Collection that is ".size()"able . d) Make the MovieManager retrieve some structure like a Map or a Collection of a two component array or something like that that will contain both a Movie object and the associated number of comments and with JSLT iterate over it and show it accordingly.

  • How to associate newly created SurfaceHolder to MediaPlayer

    - by fayerth
    In my code, I want to be able to temporarily hide (and subsequently show) a video. I am using a SurfaceView + MediaPlayer combination instead of the VideoView due to requirements. However, I am facing difficulties in getting video playback to occur as expected after I show the SurfaceView. My code excerpts includes the following: public void show() { if (mSurface != null) mSurface.setVisibility(View.VISIBLE); } public void hide() { if (mSurface != null) { if (isInPlaybackState()) pause(); mSurface.setVisibility(View.INVISIBLE); } } @Override public void surfaceCreated(final SurfaceHolder holder) { mHolder = holder; openVideo(); } @Override public void surfaceDestroyed(final SurfaceHolder holder) { // After this, the surface can't be used again mHolder = null; } private void openVideo() { if (mAssetPath == null || !mAssetPath.isEmpty() || mHolder == null) { // Not ready yet; try again later return; } // Pause music playback service Intent i = new Intent("com.android.music.musicservicecommand"); i.putExtra("command", "pause"); getActivity().sendBroadcast(i); if (mPlayer == null) { initializePlayer(); } else { mPlayer.setDisplay(mHolder); } } Based on the above, when I call hide(), surfaceDestroyed(SurfaceHolder) gets triggered. When I later call show(), surfaceCreated(SurfaceHolder) gets triggered, which will call openVideo() and associate the player with the newly provided SurfaceHolder. The above works as expected, and I believe this should be the correct process; however, when I call mPlayer.start(), I would hear the video's audio playing without any video and see the following error messages (which eventually causes the media playback to stop and complete, as noted by the disconnect logs): 10-23 11:29:42.775: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.795: E/MediaPlayer(4204): Error (-38,0) 10-23 11:29:42.805: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.810: V/MediaPlayer(4204): message received msg=100, ext1=1, ext2=-2147483648 10-23 11:29:42.810: E/MediaPlayer(4204): error (1, -2147483648) 10-23 11:29:42.810: V/MediaPlayer(4204): callback application 10-23 11:29:42.810: V/MediaPlayer(4204): back from callback 10-23 11:29:42.825: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.850: V/MediaPlayer-JNI(4204): getCurrentPosition: 671668 (msec) 10-23 11:29:42.850: V/MediaPlayer-JNI(4204): getCurrentPosition: 671668 (msec) 10-23 11:29:42.850: V/MediaPlayer(4204): message received msg=100, ext1=1, ext2=-2147483648 10-23 11:29:42.850: E/MediaPlayer(4204): error (1, -2147483648) 10-23 11:29:42.850: V/MediaPlayer(4204): callback application 10-23 11:29:42.850: V/MediaPlayer(4204): back from callback 10-23 11:29:42.875: V/MediaPlayer-JNI(4204): stop 10-23 11:29:42.875: V/MediaPlayer(4204): stop 10-23 11:29:42.875: E/MediaPlayer(4204): stop called in state 0 10-23 11:29:42.875: V/MediaPlayer(4204): message received msg=100, ext1=-38, ext2=0 10-23 11:29:42.875: E/MediaPlayer(4204): error (-38, 0) 10-23 11:29:42.875: V/MediaPlayer(4204): callback application 10-23 11:29:42.875: V/MediaPlayer(4204): back from callback 10-23 11:29:42.875: V/MediaPlayer-JNI(4204): reset 10-23 11:29:42.875: V/MediaPlayer(4204): reset 10-23 11:29:42.900: V/MediaPlayer-JNI(4204): release 10-23 11:29:42.900: V/MediaPlayer(4204): setListener 10-23 11:29:42.900: V/MediaPlayer(4204): disconnect 10-23 11:29:42.910: V/MediaPlayer(4204): destructor 10-23 11:29:42.910: V/MediaPlayer(4204): disconnect Has anyone encountered this issue before and found a workaround? Or would the only option be to create a new MediaPlayer as well?
