  • Android: How to handle runtime exception on playing audio files?

    - by Maxood
    I have a button that plays an audio file on its click listener. If the button is clicked again and again while the audio file is being played then the app crashes. What's the solution? Here is some code for reference: private OnClickListener btnMercyListener = new OnClickListener() { public void onClick(View v) { // Toast.makeText(getBaseContext(), // "Mercy audio file is being played", // Toast.LENGTH_LONG).show(); if (status==true) { mp.stop(); mp.release(); status = false; } else { mp = MediaPlayer.create(iMEvil.this,R.raw.mercy); //mp.start(); try{ mp.start(); status= true; //mp.release(); }catch(NullPointerException e) { Log.v("MP error",e.toString()); } } mp.setOnCompletionListener(new OnCompletionListener(){ // @Override public void onCompletion(MediaPlayer arg0) { mp.release(); status = false; } } ); } };

  • Upload Image with Django Model Form

    - by jmitchel3
    I'm having difficulty uploading the following model with model form. I can upload fine in the admin but that's not all that useful for a project that limits admin access. #Models.py class Profile(models.Model): name = models.CharField(max_length=128) user = models.ForeignKey(User) profile_pic = models.ImageField(upload_to='img/profile/%Y/%m/') #views.py def create_profile(request): try: profile = Profile.objects.get(user=request.user) except: pass form = CreateProfileForm(request.POST or None, instance=profile) if form.is_valid(): new = form.save(commit=False) new.user = request.user new.save() return render_to_response('profile.html', locals(), context_instance=RequestContext(request)) #Profile.html <form enctype="multipart/form-data" method="post">{% csrf_token %} <tr><td>{{ form.as_p }}</td></tr> <tr><td><button type="submit" class="btn">Submit</button></td></tr> </form> Note: All the other data in the form saves perfectly well, the photo does not upload at all. Thank you for your help!

  • Linear layout and custom dialog

    - by DixieFlatline
    The button doesn't show in this layout(code below),image and textview are shown. I tried using relative layout but that doesn't help either. I'm testing it on 1.5 emulator. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/layout_root" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" > <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/neki" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ImageView android:id="@+id/image" android:layout_width="wrap_content" android:layout_height="fill_parent" android:layout_marginRight="10dp" /> <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="fill_parent" android:textColor="#FFF" android:text="Some text " /> </LinearLayout> <Button android:id="@+id/gumbek" android:text="V redu" android:typeface="serif" android:textStyle="bold" android:layout_width="fill_parent" android:layout_height="wrap_content" /> </LinearLayout>

  • How to have other divs with a flash liquid layout that fits to the page?

    - by brybam
    Basically the majority of my content is flash based. I designed it using Flash Builder (Flex) and Its in a liquid layout, (everything is in percents) and if im JUST embedding the flash content it scales to the page fine, and i have the flash content set to have a padding of 50 px. I put a header div in fine with no problems, but I have 2 problems, the first being the footer div seems to cover up the buttom of the flash content in IE, but it looks just fine in chrome. How can I solve this? I'm using the stock embed code that Flex provides, I tried to edit the css style for the div which I think is #flashContent and give it a min width and min height but it didnt seem to work, actually anything I did to #flashContent didn't seem to do anything, maybe its not the div i need to be adding that attribute to... And my other problem is I dont even know where to start when it comes to placing a div thats 280width by 600height colum to the right side of the flash content. If i could specify a size for the flash content, and the float it left, and float the colum right, and clear it with the container div id be just fine....But remember the flash content is set to 100% Scale (well techically 100%x80% because it looked better that way). Does anyone know how I can start to deal with creating a more complex scaleable flash layouts that includes other divs? ALL WELL MAINTAINING IE SUPPORT? IE is ruining my life. Here's the code I'm using: (or if it will help you visualize what im trying to do here's the page where im working on setting this up http://apumpkinpatch.com/textmashnew/) <!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" lang="en" xml:lang="en"> <head> <title>TextMixup</title> <meta name="google" value="notranslate"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link href="css.css" rel="stylesheet" type="text/css" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script> <script src="../appassets/scripts/jquery.titlealert.js"></script> <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-19768131-2']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ?

  • How To: UiBinder + GWT MVP + multiple independent display areas

    - by Prt Yz
    I am using GWT MVP and UiBinder to create an app with a DockLayoutPanel. I want the north and south docks to be static, containing buttons and links. I want to have dynamic views in the center and two different areas of the east dock. As these dynamic areas should be independent of each other, I am setting up different ActivityMapper and ActivityManager's for each dynamic display area; center, east-top, and east-bottom. How can I independently initialize these 3 different display areas when the application is loaded? How can I switch from one Activity to another in one display area without affecting the other areas? When I use the the PlaceController's goTo to switch from one Place to another in one area, the other area's Activity is stopped. Mayday, please help, mayday! The following is some of my code: AppViewImpl.ui.xml <g:DockLayoutPanel styleName="{style.dockPanel}" unit="PX" width="975px" height="100%"> <!-- DOCK PANEL EAST --> <g:east size="220"> <g:LayoutPanel styleName="{style.eastPanel}"> <g:layer left="0px" width="220px" top="0px" height="105px"> <g:SimpleLayoutPanel ui:field="topRightPanel"/> </g:layer> <g:layer left="0px" width="220px" top="110px" height="340px"> <g:InlineLabel styleName="{style.label}" text="ANOTHER DISPLAY AREA"/> </g:layer> </g:LayoutPanel> </g:east> <!-- DOCK PANEL NORTH --> <g:north size="110"> <g:LayoutPanel styleName="{style.northPanel}"> <g:layer left="0px" width="755px" top="0px" height="105px"> <g:InlineLabel styleName="{style.label}" text="NORTH PANEL"/> </g:layer> </g:LayoutPanel> </g:north> <!-- DOCK PANEL SOUTH --> <g:south size="20"> <g:LayoutPanel styleName="{style.southPanel}"> <g:layer left="0px" width="755px" top="0px" height="20px"> <g:InlineLabel styleName="{style.label}" text="SOUTH PANEL"/> </g:layer> </g:LayoutPanel> </g:south> <!-- DOCK PANEL CENTER --> <g:center> <g:SimpleLayoutPanel ui:field="mainPanel" /> </g:center> </g:DockLayoutPanel> MyModule.java public class MyModule implements EntryPoint { private Place defaultPlace = new DefaultPlace(""); public void onModuleLoad() { // Create ClientFactory using deferred binding so we can replace with // different impls in gwt.xml ClientFactory clientFactory = GWT.create(ClientFactory.class); EventBus eventBus = clientFactory.getEventBus(); PlaceController placeController = clientFactory.getPlaceController(); // Start ActivityManager for the main widget with our ActivityMapper ActivityMapper topRightActivityMapper = new TopRightActivityMapper(clientFactory); ActivityManager topRightActivityManager = new ActivityManager(topRightActivityMapper, eventBus); topRightActivityManager.setDisplay(clientFactory.getAppView().getTopRightPanel()); // Start ActivityManager for the main widget with our ActivityMapper ActivityMapper mainActivityMapper = new AppActivityMapper(clientFactory); ActivityManager mainActivityManager = new ActivityManager(mainActivityMapper, eventBus); mainActivityManager.setDisplay(clientFactory.getAppView().getMainPanel()); // Start PlaceHistoryHandler with our PlaceHistoryMapper AppPlaceHistoryMapper historyMapper = GWT .create(AppPlaceHistoryMapper.class); PlaceHistoryHandler historyHandler = new PlaceHistoryHandler(historyMapper); historyHandler.register(placeController, eventBus, defaultPlace); RootLayoutPanel.get().add(clientFactory.getAppView()); // Goes to place represented on URL or default place historyHandler.handleCurrentHistory(); new AppController(clientFactory); } } AppController.java public class AppController implements AppView.Presenter { private ClientFactory clientFactory; AppController(ClientFactory clientFactory){ this.clientFactory = clientFactory; goTo(new TopRightAPlace("")); } @Override public void goTo(Place place) { clientFactory.getPlaceController().goTo(place); } } TopRightAViewImpl.java public class TopRightAViewImpl extends Composite implements TopRightAView { interface Binder extends UiBinder<Widget, TopRightAViewImpl> { } private static final Binder binder = GWT.create(Binder.class); private Presenter listener; @UiField Button button; public TopRightAViewImpl() { initWidget(binder.createAndBindUi(this)); } @Override public void setName(String name) { button.setHTML(name); } @Override public void setPresenter(Presenter listener) { this.listener = listener; } @UiHandler("button") void onButtonClick(ClickEvent event) { listener.goTo(some other place); } }

  • When would ShowDialog() return null?

    - by Joe White
    WPF's Window.ShowDialog method returns a nullable boolean. So does CommonDialog.ShowDialog. Now, I understand cases where these would return false (user clicked Cancel or pressed Esc), and when they would return true (code sets Window.DialogResult to true, probably in response to OK being clicked). But null? My first thought is that clicking the title bar's Close button might return null. But the docs state (and I confirmed by testing) that the title-bar Close button is treated as a Cancel. So when would Window.ShowDialog or CommonDialog.ShowDialog ever return null?

  • checkins/recent not returning comments or even counts of comments

    - by Gilbert
    My application has been using the checkins/recent endpoint to show where all the current users friends are currently at and I had included a button the user could press to comment on a checkin. The button used to have the comment count on it until recently. It seems the checkins/recent endpoint no longer returns comments or even a comment count for those checkins. I would have to query each checkin in order to get the comment count which adds to the data usage not to mention API usage counts. Is there another way to do this that I'm not seeing? Could you please at least put the comment count back? You have the photo information, why not comments? Thanks

  • Internet Explorer blocked this website from displaying content with security certificate errors

    - by Tabrez
    I have a security certificate linked to a CDN's server. The main website is https:www.connect4fitness.com When I pull the site up in firefox or chrome, everything works fine. But in IE I get the following error: "Internet Explorer blocked this website from displaying content with security certificate errors." On IE 9 it shows the button "Display Content" and you can get past the error by clicking on the button. On older versions on I the error message is much more cryptic and is confusing users. Please note that I don't have the option of asking end users to add the site to Trusted Sources as some folks use the site from their work computers and do not have that access. Also, some people don't bother to call once they hit the error. I have looked at the content and all my links are "https" only. I had one namespace link and I got rid of it. Any idea about how I can find what is triggering this message?

  • Using Add-on SDK to add toolbar buttons? Integrating XUL and Add-on SDK for Firefox Add-ons?

    - by Salami
    I have already coded most of a Firefox add-on using the Add-on SDK API. I am now discovering that Add-on SDK might not be powerful enough for my purposes. I need two things: A drop down button in the toolbar next to the location bar. To modify the add-ons manager in firefox It is truly disappointing, but I don't believe either of these is possible with the Add-on SDK. First of all, I understand there is a widget module in the Add-on SDK API. But this only allows me to add a simple icon or label to the awkward add-on bar. What if I need to add a nicer button like the one next to the location bar for Firebug or Greasemonkey? As for modifying the add-ons manager in firefox, I have tried Nickolay Ponomarev's XUL with the Add-on SDK without any success whatsoever. If anyone knows how to get this working and can point me in the right direction that would be extremely helpful (cfx init --template xul doesn't do anything the regular SDK does when I try it)

  • C# CF: encryption/decryption

    - by nuttynibbles
    Hi, i've seen many article on encrypt/decrypt of file and typically a button is used to choose the file for encrypt and another button to decrypt the file. i've seen some application like truecrypt and probably others which does file encryption on-the-fly with transparent. this means that when a encrypted file is clicked to access, it will automatically decrypt and play/open the file. then when the file is closed, it will automatically encrypt again. what are the ways to do this in c# compact framework?

  • Use ModalPopupExtender without having to set TargetControlID?

    - by Monty
    I'd like to use a modalpopupextender in my asp.net page to show a sub form. But it only has to show on specific conditions. Those conditions are determined in a piece of javascript code. So, most importantly, the modal popup doesn't have to show on a button click. However, if I leave the property TargetControlID empty I get the following exception: The TargetControlID of 'ModalPopupExtender1' is not valid. The value cannot be null or empty. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: The TargetControlID of 'ModalPopupExtender1' is not valid. The value cannot be null or empty. Do I just have the TargetControlID to an hidden button or is there aslo a more decent option? Thanks.

  • Ajax Control Toolkit May 2012 Release

    - by Stephen.Walther
    I’m happy to announce the May 2012 release of the Ajax Control Toolkit. This newest release of the Ajax Control Toolkit includes a new file upload control which displays file upload progress. We’ve also added several significant enhancements to the existing HtmlEditorExtender control such as support for uploading images and Source View. You can download and start using the newest version of the Ajax Control Toolkit by entering the following command in the Library Package Manager console in Visual Studio: Install-Package AjaxControlToolkit Alternatively, you can download the latest version of the Ajax Control Toolkit from CodePlex: http://AjaxControlToolkit.CodePlex.com The New Ajax File Upload Control The most requested new feature for the Ajax Control Toolkit (according to the CodePlex Issue Tracker) has been support for file upload with progress. We worked hard over the last few months to create an entirely new file upload control which displays upload progress. Here is a sample which illustrates how you can use the new AjaxFileUpload control: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="01_FileUpload.aspx.cs" Inherits="WebApplication1._01_FileUpload" %> <html> <head runat="server"> <title>Simple File Upload</title> </head> <body> <form id="form1" runat="server"> <div> <ajaxToolkit:ToolkitScriptManager runat="server" /> <ajaxToolkit:AjaxFileUpload id="ajaxUpload1" OnUploadComplete="ajaxUpload1_OnUploadComplete" runat="server" /> </div> </form> </body> </html> The page above includes a ToolkitScriptManager control. This control is required to use any of the controls in the Ajax Control Toolkit because this control is responsible for loading all of the scripts required by a control. The page also contains an AjaxFileUpload control. The UploadComplete event is handled in the code-behind for the page: namespace WebApplication1 { public partial class _01_FileUpload : System.Web.UI.Page { protected void ajaxUpload1_OnUploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e) { // Generate file path string filePath = "~/Images/" + e.FileName; // Save upload file to the file system ajaxUpload1.SaveAs(MapPath(filePath)); } } } The UploadComplete handler saves each uploaded file by calling the AjaxFileUpload control’s SaveAs() method with a full file path. Here’s a video which illustrates the process of uploading a file: Warning: in order to write to the Images folder on a production IIS server, you need Write permissions on the Images folder. You need to provide permissions for the IIS Application Pool account to write to the Images folder. To learn more, see: http://learn.iis.net/page.aspx/624/application-pool-identities/ Showing File Upload Progress The new AjaxFileUpload control takes advantage of HTML5 upload progress events (described in the XMLHttpRequest Level 2 standard). This standard is supported by Firefox 8+, Chrome 16+, Safari 5+, and Internet Explorer 10+. In other words, the standard is supported by the most recent versions of all browsers except for Internet Explorer which will support the standard with the release of Internet Explorer 10. The AjaxFileUpload control works with all browsers, even browsers which do not support the new XMLHttpRequest Level 2 standard. If you use the AjaxFileUpload control with a downlevel browser – such as Internet Explorer 9 — then you get a simple throbber image during a file upload instead of a progress indicator. Here’s how you specify a throbber image when declaring the AjaxFileUpload control: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="02_FileUpload.aspx.cs" Inherits="WebApplication1._02_FileUpload" %> <html> <head id="Head1" runat="server"> <title>File Upload with Throbber</title> </head> <body> <form id="form1" runat="server"> <div> <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" /> <ajaxToolkit:AjaxFileUpload id="ajaxUpload1" OnUploadComplete="ajaxUpload1_OnUploadComplete" ThrobberID="MyThrobber" runat="server" /> <asp:Image id="MyThrobber" ImageUrl="ajax-loader.gif" Style="display:None" runat="server" /> </div> </form> </body> </html> Notice that the page above includes an image with the Id MyThrobber. This image is displayed while files are being uploaded. I use the website http://AjaxLoad.info to generate animated busy wait images. Drag-And-Drop File Upload If you are using an uplevel browser then you can drag-and-drop the files which you want to upload onto the AjaxFileUpload control. The following video illustrates how drag-and-drop works: Remember that drag-and-drop will not work on Internet Explorer 9 or older. Accepting Multiple Files By default, the AjaxFileUpload control enables you to upload multiple files at a time. When you open the file dialog, use the CTRL or SHIFT key to select multiple files. If you want to restrict the number of files that can be uploaded then use the MaximumNumberOfFiles property like this: <ajaxToolkit:AjaxFileUpload id="ajaxUpload1" OnUploadComplete="ajaxUpload1_OnUploadComplete" ThrobberID="throbber" MaximumNumberOfFiles="1" runat="server" /> In the code above, the maximum number of files which can be uploaded is restricted to a single file. Restricting Uploaded File Types You might want to allow only certain types of files to be uploaded. For example, you might want to accept only image uploads. In that case, you can use the AllowedFileTypes property to provide a list of allowed file types like this: <ajaxToolkit:AjaxFileUpload id="ajaxUpload1" OnUploadComplete="ajaxUpload1_OnUploadComplete" ThrobberID="throbber" AllowedFileTypes="jpg,jpeg,gif,png" runat="server" /> The code above prevents any files except jpeg, gif, and png files from being uploaded. Enhancements to the HTMLEditorExtender Over the past months, we spent a considerable amount of time making bug fixes and feature enhancements to the existing HtmlEditorExtender control. I want to focus on two of the most significant enhancements that we made to the control: support for Source View and support for uploading images. Adding Source View Support to the HtmlEditorExtender When you click the Source View tag, the HtmlEditorExtender changes modes and displays the HTML source of the contents contained in the TextBox being extended. You can use Source View to make fine-grain changes to HTML before submitting the HTML to the server. For reasons of backwards compatibility, the Source View tab is disabled by default. To enable Source View, you need to declare your HtmlEditorExtender with the DisplaySourceTab property like this: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="05_SourceView.aspx.cs" Inherits="WebApplication1._05_SourceView" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head id="Head1" runat="server"> <title>HtmlEditorExtender with Source View</title> </head> <body> <form id="form1" runat="server"> <div> <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" /> <asp:TextBox id="txtComments" TextMode="MultiLine" Columns="60" Rows="10" Runat="server" /> <ajaxToolkit:HtmlEditorExtender id="HEE1" TargetControlID="txtComments" DisplaySourceTab="true" runat="server" /> </div> </form> </body> </html> The page above includes a ToolkitScriptManager, TextBox, and HtmlEditorExtender control. The HtmlEditorExtender extends the TextBox so that it supports rich text editing. Notice that the HtmlEditorExtender includes a DisplaySourceTab property. This property causes a button to appear at the bottom of the HtmlEditorExtender which enables you to switch to Source View: Note: when using the HtmlEditorExtender, we recommend that you set the DOCTYPE for the document. Otherwise, you can encounter weird formatting issues. Accepting Image Uploads We also enhanced the HtmlEditorExtender to support image uploads (another very highly requested feature at CodePlex). The following video illustrates the experience of adding an image to the editor: Once again, for backwards compatibility reasons, support for image uploads is disabled by default. Here’s how you can declare the HtmlEditorExtender so that it supports image uploads: <ajaxToolkit:HtmlEditorExtender id="MyHtmlEditorExtender" TargetControlID="txtComments" OnImageUploadComplete="MyHtmlEditorExtender_ImageUploadComplete" DisplaySourceTab="true" runat="server" > <Toolbar> <ajaxToolkit:Bold /> <ajaxToolkit:Italic /> <ajaxToolkit:Underline /> <ajaxToolkit:InsertImage /> </Toolbar> </ajaxToolkit:HtmlEditorExtender> There are two things that you should notice about the code above. First, notice that an InsertImage toolbar button is added to the HtmlEditorExtender toolbar. This HtmlEditorExtender will render toolbar buttons for bold, italic, underline, and insert image. Second, notice that the HtmlEditorExtender includes an event handler for the ImageUploadComplete event. The code for this event handler is below: using System.Web.UI; using AjaxControlToolkit; namespace WebApplication1 { public partial class _06_ImageUpload : System.Web.UI.Page { protected void MyHtmlEditorExtender_ImageUploadComplete(object sender, AjaxFileUploadEventArgs e) { // Generate file path string filePath = "~/Images/" + e.FileName; // Save uploaded file to the file system var ajaxFileUpload = (AjaxFileUpload)sender; ajaxFileUpload.SaveAs(MapPath(filePath)); // Update client with saved image path e.PostedUrl = Page.ResolveUrl(filePath); } } } Within the ImageUploadComplete event handler, you need to do two things: 1) Save the uploaded image (for example, to the file system, a database, or Azure storage) 2) Provide the URL to the saved image so the image can be displayed within the HtmlEditorExtender In the code above, the uploaded image is saved to the ~/Images folder. The path of the saved image is returned to the client by setting the AjaxFileUploadEventArgs PostedUrl property. Not surprisingly, under the covers, the HtmlEditorExtender uses the AjaxFileUpload. You can get a direct reference to the AjaxFileUpload control used by an HtmlEditorExtender by using the following code: void Page_Load() { var ajaxFileUpload = MyHtmlEditorExtender.AjaxFileUpload; ajaxFileUpload.AllowedFileTypes = "jpg,jpeg"; } The code above illustrates how you can restrict the types of images that can be uploaded to the HtmlEditorExtender. This code prevents anything but jpeg images from being uploaded. Summary This was the most difficult release of the Ajax Control Toolkit to date. We iterated through several designs for the AjaxFileUpload control – with each iteration, the goal was to make the AjaxFileUpload control easier for developers to use. My hope is that we were able to create a control which Web Forms developers will find very intuitive. I want to thank the developers on the Superexpert.com team for their hard work on this release.

  • PDF form submission

    - by Jeff
    I have a PDF form (made in Acrobat) that has button to submit via HTTP. What I want to do it have a PHP script that will take the PDF form and e-mail it to me via attachment. What I don't want: --PDF Submit via e-mail button. This requires webmail users to save the pdf and attach it, and is just too confusing for most users. I want one-click and done. --Submit via mailto:[email protected]. Does the same thing as above. If there's a pdf on the server, I know how to use PHP's mail() function to e-mail it to someone. What I don't know how to do is process the PDF once someone hits Submit within the PDF. Does that make sense? Thanks, Jeff

  • How to handle runtime exception on playing audio files?

    - by Maxood
    I have a button that plays an audio file on its click listener. If the button is clicked again and again while the audio file is being played then the app crashes. What's the solution? Here is some code for reference: private OnClickListener btnMercyListener = new OnClickListener() { public void onClick(View v) { // Toast.makeText(getBaseContext(), // "Mercy audio file is being played", // Toast.LENGTH_LONG).show(); if (status==true) { mp.stop(); mp.release(); status = false; } else { mp = MediaPlayer.create(iMEvil.this,R.raw.mercy); //mp.start(); try{ mp.start(); status= true; //mp.release(); }catch(NullPointerException e) { Log.v("MP error",e.toString()); } } mp.setOnCompletionListener(new OnCompletionListener(){ // @Override public void onCompletion(MediaPlayer arg0) { mp.release(); status = false; } } ); } };

  • XCode automatically deactivating breakpoints

    - by Brian Postow
    I'm using xcode in C++. I'm trying to debug my project, but at random intervals, it seems to ignore my breakpoints. There are three things that it does: 1) Sometimes, when I run, it automatically switches to "de-activate break points" mode. (the relevant button goes light and says "Activate") 2) Sometimes when I run, ALL of my breakpoints go "can't find" mode, with the yellow insides. I need to click twice on them to get them back dark blue (once to light blue = inactive, once to dark blue = active) 3) Sometimes, when I run, my breakpoint is dark blue, the button says "deactivate" and it still just ignores my breakpoint, running straight past it. This makes it very difficult to debug my program... I should add that I'm using XCode 3.1 beta on OSX 10.5.6, in case that matters. thanks.

  • Why is android:FLAG_BLUR_BEHIND creating a gradient background in my new activity instead of bluring

    - by nderraugh
    Hi, I've got two activities. One is supposed to be a blur in front of the other. The background activity has several ImageViews which are set up as thin gradients extending across most of the screen and 10dip high. When I start the second activity it sets the background as a gradient occupying the entire window space, that is it appears to be fill_parent'd for both height and width. If I comment out the ImageViews then it blurs and looks as expected. Any thoughts? Here's the code doing the blur. import android.app.Activity; import android.os.Bundle; import android.view.View; import android.view.WindowManager; import android.view.View.OnClickListener; public class TransluscentBlurSummaryB extends Activity { @Override protected void onCreate(Bundle icicle) { super.onCreate(icicle); getWindow().setFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND, WindowManager.LayoutParams.FLAG_BLUR_BEHIND); getWindow().getAttributes().dimAmount = 0.5f; getWindow().setFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND, WindowManager.LayoutParams.FLAG_DIM_BEHIND); setContentView(R.layout.sheetbdetails); OnClickListener clickListener = new OnClickListener() { public void onClick(View v) { TransluscentBlurSummaryB.this.finish(); } }; findViewById(R.id.sheetbdetailstable).setOnClickListener(clickListener); } } And here's the layout with the ImageView gradients. <?xml version="1.0"
