  • html5 video player with simplest controls (only play and paus)

    - by mathiregister
    hi guys, somehow there are really little tutorials out there for html5 video and audio playback. I simply want to embed video and audio files with customized controls. However the controls should be farely simple. I only need a play-button. If clicked, play gets replaced by pause. that's all! however i even don't know how to embed/display a video without "preload controls". Somehow if i only set (without preload controls) Firefox even don't shows anything. Chrome does show a black window. I would love to be able to use jquery to control the video play and pause button. Maybe you have some little start-approach for me! thank you very much!

  • how to copy char * into a string and vice-versa

    - by user295030
    If i pass a char * into a function. I want to then take that char * convert it to a std::string and once I get my result convert it back to char * from a std::string to show the result. I don't know how to do this for conversion ( I am not talking const char * but just char *) I am not sure how to manipulate the value of the pointer I send in. so steps i need to do take in a char * convert it into a string. take the result of that string and put it back in the form of a char * return the result such that the value should be available outside the function and not get destroyed. If possible can i see how it could be done via reference vs a pointer (whose address I pass in by value however I can still modify the value that pointer is pointing to. so even though the copy of the pointer address in the function gets destroyed i still see the changed value outside. thanks!

  • Strange WPF Behaviour With WCF Async calls

    - by gvigsgb
    I have a WPF application calling WCF via Async calls. The application has four tabs in which each are loaded from seperate async calls, each tab has a busy indicator. The problem: When running within Visual Studio I can click a refresh button on each tab and each tab's busy indicator starts and the data is retrieved from the WCF service. As each tab's data comes back it is refreshed. When I deploy the application via one click the application's UI hangs after only two tabs start refreshing. So in this case I press refresh on tab one, then on tab two and the application hangs until one of the two tabs data comes back. I thought at first that it was something to do with the WCF service throtteling and that was not the case as both the Visual Studio and the One Click deployments of the application point to the same service. Anyone have any ideas on where to look? I cannot reproduce the hang issue within Visual Studio?

  • Serialize Dictionary with a string key and List[] value to JSON

    - by Patrick
    How can I serialize a python Dictionary to JSON and pass back to javascript, which contains a string key, while the value is a List (i.e. []) if request.is_ajax() and request.method == 'GET': groupSet = GroupSet.objects.get(id=int(request.GET["groupSetId"])) groups = groupSet.groups.all() group_items = [] #list groups_and_items = {} #dictionary for group in groups: group_items.extend([group_item for group_item in group.group_items.all()]) #use group as Key name and group_items (LIST) as the value groups_and_items[group] = group_items data = serializers.serialize("json", groups_and_items) return HttpResponse(data, mimetype="application/json") the result: [{"pk": 5, "model": "myApp.group", "fields": {"name": "\u6fb4\u9584", "group_items": [13]}}] while the group_items should have many group_item and each group_item should have "name", rather than only the Id, in this case the Id is 13. I need to serialize the group name, as well as the group_item's Id and name as JSON and pass back to javascript. I am new to Python and Django, please advice me if you have a better way to do this, appreciate. Thank you so much. :)

  • windows control library in c sharp

    - by apals
    I have just added a textbox, button, label to validate ID of 12 characters. The library is called check_ID. It works fine. The only problem is i have to access the forecolor of label, backcolor of textbox , forecolor of button as per color scheme of the project. But it seems that none of the properties of the objects in check_ID are available for modification. I have even changed the modifier to public of all objects by repoening the check_ID project. Is there another way to access the properties of these objects that are created using windows control library?. A very big thanks in advance.

  • Activity ignore intent's extra fields

    - by ced
    For example, In an ActivityA there's a button to create an Intent that will start ActivityB in a new task, like this: Intent i = new Intent(this, ActivityB.class); i.setData(Uri.parse("http://www.google.com")); long timestamp = System.currentTimeMillis(); i.putExtra("ts", timestamp); i.addFlag(Intent.FLAG_ACTIVITY_NEW_TASK); Log.d(TAG, "Sending: " + timestamp); startActivity(i); Then in ActivityB's onResume() method, there's this code to check the timestamp: long timestamp = getIntent().getExtras().getLong("ts"); Log.d(TAG, "Receiving: " + timestamp); Now the first time I invoke ActivityB from ActivityA I get the following logs: Sending: 120006000 Receiving: 120006000 Then if I left ActivityB running in the background (by pressing Home button), and start ActivityA then invoke ActivityB again, the following is printed: Sending: 120013000 Receiving: 120006000 It seems although ActivityB is brought to front by the new Intent. The extra field in the intent is being left behind. Is this a bug or an intended behavior?

  • Can anyone explain why this behaviour might be happening in Windows Forms?

    - by gizgok
    I'm developing a Windows Forms Application. See attached image for the Interface. Now I've put a close button (X) in the Panel(say Panel2) which has Application Constants as label.The first combo box is in another panel(say Panel1). Now when I click on the X button in Panel 2 I want the Panel to be invisible and the combo box text to be blank. Simple enough. So I write Panel2.visible=false; comboBox1.SelectedIndex=-1; When I click on X, the text in combo box goes blank, then I have to click again for the Panel2 to go invisible. Then I changed the sequence comboBox1.SelectedIndex=-1; Panel2.visible=fasle; and this works smooth. Not sure why this might be happening? Is there anything that I might be doing with my form design/code to have such a behaviour?

  • Capturing WPF Vector Information BEFORE it Renders to Screen

    - by user273722
    I'm trying to "capture" or record the vector display information of a WPF (maybe Silverlight) application and play it back. However, instead of capturing bitmaps of what is rendered, I would like to capture the vector information BEFORE it gets rendered so that I can play it back at different resolutions without loss of quality. Ideally, I'd like to do this without having to add assemblies into my app (but willing to do so if necessary). I've looked into the WPF rendering pipeline and cannot find an appropriate starting point (or, stated differently, I couldn't figure it out). Maybe the VisualTreeHelper class?

  • How to window.open with a toolbar in Google Chrome?

    - by brahn
    The following javascript opens a pop-up in Firefox, Safari, IE, and Google Chrome: window.open("http://google.com", "foo", "toolbar=yes,location=yes,menubar=yes") However, in Google Chrome the toolbar (with the usual forward and back buttons, etc.) does not appear on the popped-up window. (Tested on both Windows and Mac.) How can I fix this? I would like the user to be able to navigate forward and back using the tools with which they are most familiar. Thanks!

  • Problem loading js content with ajax

    - by Justin Goodman
    I have a page that loads content into a single div via a script in the page. It works fine but the problem is that I have a lightbox in one of the dynamically loaded pages that only works the first time you navigate to it (the script I got for the page loading is found here). Once you navigate to another area, then back again, the lightbox fails to work and instead just loads the plain image. It's been suggested that the easiest way to fix this would be to have a script unload the js and css that is loaded in with the page, then reload it when you go back to the gallery section. I'm a designer, not a developer though, so I don't know if this is true or not. Any help is really appreciated. The page can be found here: justgooddesign.net/graduation/

  • Images appear in simulator but not when uploading to ipod touch (3.0)

    - by user139190
    I created a simple test app with an image (as well as a button with an image) and it runs fine in the simulator. But when uploading to the iPod, none of the images appear. The button appears but with no image. A few things worth mentioning: - Today's massive achievement was making it beyond the code signing errors and so I have not had any applications uploaded to the device until now. IOW, it's not a sudden change. - The png image is about 100 x 200. - I also set an icon image (png 24 x 24) that does not appear either. Thanks in advance for any advice.

  • JSP Problem ussing implicit object (session) in a function

    - by user234666
    Can the object of type HttpSession called session be accessed from a function? In a simple jsp page I have a function(see below) defined in the header of the page, and set to an onclick handle of for a button. When I press this button, I'll never see the second alert message. If I do something in the body of the page (like Session ID: <%= session.getId() % ) I have no trouble accessing it. What newbie mistake am I making? function doTest() { alert('Preforming test 122333232'); String sessionId = session.getId(); alert('After access'); if(sessionId == null) { alert('session id is null?'); } Thanks

  • Force Hibernate To Save A Specific POJO

    - by user1695626
    I have some code calling a webservice and it returns an id. I am saving this id in the database using hibernate. I have a filter that opens the session and commits it, rolling back when any exception occurs within the contained code. Since there is no way to get back the id returned by the webservice I would like to save this in the database EVEN if there is an exception that occurred later on in the code. Is there anyway to do this using the same session?

  • iPhone - Landscape Only App

    - by Robert
    Hello all! I am trying to make an app that will only be viewed in Landscape. I have looked up some tutorials (albeit older ones) and have done the following: -set up the info.plist to include a key for uiinterfaceorientation -in the main view controller I have set the frame to be 480 x 320 Now, the first screen loads up ok. Everything is where it should be and whatnot. However, if I click a button that is set to present a modal view controller nothing happens. Everything is linked and coded correctly but nothing happens when I press the button. Am I doing something wrong with trying to force landscape? At it's basic, this question is a how do you effectively make an app that will only be in landscape mode? Thanks for any help.

  • Unfortunately App stopped when destroying SupportMapFragment

    - by user1408341
    I have the following problem. I have three fragments which are hosted in a TabHost. When I'm working with the app everything works fine. Now I like to end the app when the user hits the back button. Instead of terminating without errors I get the message Unfortunately App stopped. Then I said to myself something is wrong with the onDestroy() method of the FragmentActivity or with the onDestroyView method() of the Fragment. The problem is I cannot debug the point where the app crash. I get only the error:Fatal signal 11 (SIGSEGV). I then removed one by one each Fragment to identify which fragment causes the error. I could identify the fragment that I named BasicMapFragment. Something is wrong there. The code: public class BasicMapFragment extends SupportMapFragment implements LocationListener { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = super.onCreateView(inflater, container, savedInstanceState); //removeAllMarkers(); //setupGps(); //setupMap(); //setupMarkersFromModel(); //registerListeners(); return view; } } I commented out all my self written code to isolate the place where the error occurs. @Override public void onDestroy() { Log.d("ch.xxx.fragment.BasiceMapFragment", "On destroy called"); super.onDestroy(); } public void onDestroyView() { Log.d("ch.xxx.fragment.BasiceMapFragment", "On destroy view called"); super.onDestroyView(); } When I press the back button now the onDestroy() method of my FragmentActivity is first called like expected. Then the onDestroyView method is called on my BasicMapFragment class. At the end the onDestroy method is called - and then the application crash. Here is my layout file: <?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent"> <fragment android:id="@+id/map" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment"/> </FrameLayout> Resume: - Map is showed - I can work with the app. - When I leave out the BasicMapFragment the app finish without error. - When I add the BasicMapFragment the app returns an error when I press the back button Is there something that I have forgot to implement? Have somebody had the same trouble?

  • ActionScript 3 Context Menu Per Sprite?

    - by TheDarkIn1978
    is it not possible to have different context menus for different sprites on the stage? i've tried adding a custom context menu to a sprite but it's applied to the entire stage: mySprite.contextMenu = myMenu; then after reading the documentation where it states: You can attach a ContextMenu object to a specific button, movie clip, or text field object, or to an entire movie level. You use the menu property of the Button, MovieClip, or TextField class to do this. ok, so i though i had to write it like: mySprite.menu.contextMenu = myMenu; only to be greeted with a nice migration issue stating that menu is legacy code and to use contextMenu instead. ??? um, thanks for the headsup, documentation. this process would be entirely much more easier if i could extend the ContextMenu, but for some reason it's marked as "final" and can't be extended... i'm sure adobe's reasons for finalizing the context menu class are as good as their reasons for including misleading documentation. thoughts?

  • Jquery ajax using asp.net does not work on IE9 during the 2nd call of the function?

    - by randelramirez1
    I have gridview that is loaded from another aspx page after an ajax call, the problem is it works on chrome/firefox/safari but using ie9 the ajax call would work fine during the first call but when i try to call the function again it throws an 304 status on the network tab of ie9 dev tool and the gridview is not refreshed. Here is the jquery code: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="LoadCoursesGridViewHere.aspx.cs" Inherits="CoursesGridView" %> <!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"> <head runat="server"> <title></title> <script src="Scripts/jquery-1.8.2.js" type="text/javascript"></script> </head> <body> <form id="form1" runat="server"> <div id="Gridview-container"> <asp:GridView ID="GridView1" runat="server"> </asp:GridView> </div> <asp:TextBox ID="TextBox1" runat="server" ViewStateMode="Disabled"></asp:TextBox> <%-- <asp:Button Text="text" ID="btn" OnClientClick=" __doPostBack('UpdatePanel1', '')" runat="server" />--%> <input type="button" id="btn" value="insert"/> </form> <script type="text/javascript"> $("#btn").click(function () { var a = $("#TextBox1").val(); $.ajax({ url: 'WebService.asmx/insert', data: "{ 'name': '" + a + "' }", contentType: "application/json; charset=utf-8", type: "POST", success: function () { // alert('insert was performed.'); $("#Gridview-container").empty(); $("#Gridview-container").load("GridViewCourses.aspx #GridView1"); } }); }); </script> </body> </html> What happen is that after click the button it will insert the textbox value in the database through the webservice 'insert' and then reload the gridview that is placed inside a different aspx page. The problem is that when I ran it on IE9 during the 1st insert everything works properly but the succeeding inserts does reload the gridview and I noticed that it says '304' on the network tab of ie9 dev tool.

  • Drupal does not recognize my website has been installed

    - by Marcos Buarque
    After a successful Drupal install, I was trying to follow the security recommendations and reverted the settings.php file to 444 permissions (read, read, read). Then, all of a sudden, right after doing that, Drupal does not recognize the installation process was completed. It went back to the install screen. Worst of all. I did chmod back to 666 (write, write, write) but it does not work any more. When I move forward as if I was going to install Drupal again, he tells me he does not have permissions to create the files folder under sites/default... But since the installation has already been completed... the files folder is already there... I am puzzled... Could it be some sort of server caching? Since this is one of my first adventures with a Linux server, I am a bit confused. Any help appreciated... Thanks.

Here is an example page: http://m.stackoverflow.quickmediasolutions.com/view_question.php?id=97969&site=serverfault As you can see, the answers have a sliver of white stuffed between the top of the 'button' and the content. Here is some relevant code: <!-- this is the top of the 'button' --> <div class='top'></div> <!-- right here is where the space is --> <div class='content'></div> .top { height: 5px; } .content { display: block; padding-left: 10px; }

  • efficiently trimming postgresql tables

    - by agilefall
    I have about 10 tables with over 2 million records and one with 30 million. I would like to efficiently remove older data from each of these tables. My general algorithm is: create a temp table for each large table and populate it with newer data truncate the original tables copy tmp data back to original tables using: "insert into originaltable (select * from tmp_table)" However, the last step of copying the data back is taking longer than I'd like. I thought about deleting the original tables and making the temp tables "permanent", but I lose constraint/foreign key info. If I delete from the tables directly, it takes much longer. Given that I need to preserve all foreign keys and constraints, are there any faster ways of removing the older data? Thanks.

    Basically I have a custom UIButton and this custom button contains subviews. If I add those subviews to my uibutton, then the button stops responding to event changes. I.e if I click on it it doesn't respond to the selector. I have everything set as userInteractionEnabled. I also tried adding touchbegan and this is working. If I remove those subviews, the UIButton works again. Any help would be greatly appreciated. Cheers.
