• java applet won't work

  - by scoobi_doobi

  hey guys, this is homework stuff, but the question is not much about coding. the task is to write a java applet to work on an m-grid server. i have the server running on apache. it has a few sample applets in .jar and .class form. the .class versions work; the .jar versions work on appletviewer, but they break if I submit them as a job to the server with this: load: class examples/pixelcount/PixelCount.class not found. java.lang.ClassNotFoundException: examples.pixelcount.PixelCount.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at sun.net.NetworkClient.doConnect(Unknown Source) at sun.net.www.http.HttpClient.openServer(Unknown Source) at sun.net.www.http.HttpClient.openServer(Unknown Source) at sun.net.www.http.HttpClient.<init>(Unknown Source) at sun.net.www.http.HttpClient.New(Unknown Source) at sun.net.www.http.HttpClient.New(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.connect(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.getBytes(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader.access$000(Unknown Source) at sun.plugin2.applet.Applet2ClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) ... 7 more Exception: java.lang.ClassNotFoundException: examples.pixelcount.PixelCount.class I'm not really sure where exactly is the problem in here, given that they work on appletviewer. any help would be appreciated.. EDIT: don't know if I wrote it clearly. by ".class version" i refer to html file with this content: <applet height="300" width="450" code="examples/pixelcount/PixelCount.class"></applet> and ".jar" with this content: <applet height="300" width="450" archive="PixelCount.jar" code="examples.pixelcount.PixelCount.class"></applet>

• UITableView UITableViewCell dynamic UILabel Height storyboard

  - by Mikel Nelson

  This isn'an a question, just a results log on an issue I had with XCode 4.5 storyboards and dynamic height UITableCell with a UILabel. The issue was; the initial display of a cell would only show part of the resized UILabel contents, and that the visual UILabel was not resized. It would only display correctly after scrolling off the top of the Table and back down. I did the calculations in hieghtForRowAtIndexPath and sizeToFit the UILabel in rowAtIndexPath. The sizes where coming up ok in debug, but the device was not updating the display with the correct size and UILable.text value. I had created the dynamic UITableCell in a storyboard. However, I had set the width and height to a nominal value (290x44). It turns out, this was causing my issues. I set the width and height to zero (0) in the story board, and everything started working correctly. (i.e. the UILabels displayed at the correct size with full content). I was unable to find anything online on this issue, except for some references to creating the custom table cell with a frame of zero. Turns out, that was really the answer (for me).

• javascript toolkit for offline webapps

  - by anjanb

  hi all, we're building an survey webapp which will let the user to add new records to the survey when offline and will upload when the browser reconnects with the server. We've identified that this will need offline storage and hence google gears seems to be an obvious choice (we understand that adobe Flash has Offline Storage but not sure if that is the best way). I am aware of Dojo offline javascript toolkit which uses google gears for the underlying functionality. However, dojo offline is not part of the dojo toolkit after version 1.3. (currently dojo is 1.4.2). Google gears toolkit is currently frozen except for critical vulnerability fixes (it has not been updated almost for the last 1 yr) because they think that HTML 5 is the way to go ahead. Hence, we're looking for a higher abstraction on top of Google Gears engine TODAY, AND which will (in the future) switch the underlying engine to HTML5 if the browser supports HTML5 standards. We'd love to use Dojo but they have discontinued Dojo offline -- we'd prefer something that will be maintained for some time. Which are possible good strategies, JS toolkits/libraries to use for building this webapp ? Pls. advise.

• Moving UIScrollView in App

  - by jsetting32

  Currently, I am attempting to create the same effect as Yahoo! Weather's App where the vital day information is at the bottom of the page on the top of a UIScrollView, that's contained by a UIView. I am having a hard time thinking about how this is going to happen or how I should implement this. If the user taps on the top of the UIScrollView which is located near the bottom of the laoded UIView, and starts to scroll up (/), the UIScrollView's frame should be moved to the TOP of the current UIView's frame. So the UIScrollView's y-value should change to UIView's (self.view.frame.origin.y) if the user starts scrolling UP on the UIScrollView which is located on the UIView's y-pixel ~280. Here's what the UIViewController should look like in the beginning of loading the ViewController... Then once the user slides his finger from the bottom to the top of the screen... this should happen........ And when the user scrolls to the top of the UIScrollView with all the content within it... the view should go back to the start picture shown... How is this done? I was thinking several UIGestureRecognizer's and Instantiating the UIscrollview at the lower part of the UIView... _weatherView = [[UIScrollView alloc] initWithFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y + 250, self.view.bounds.size.width, self.view.bounds.size.height - 44)]; _weatherView.contentSize = CGSizeMake(self.view.bounds.size.width, self.view.bounds.size.height * 4); _weatherView.backgroundColor = [UIColor clearColor]; [self.view addSubview:_weatherView]; The adding some UIGestureRecognizer delegate method.... But anyone have any ideas on the UIGestureRecognizer delegate method? And how it should be implemented? I can write the psuedo-code but I am having problems finding the delegate methods :P Thank you!!! ---- Break Time.... :)

• managing html rich text selections

  - by swami

  Hi, I am writing a component for a web app which will display some html, and let me capture and manipulate the selection boundaries (of the text selected by the user). I have done this successfully (for Mozilla) with a simple div element using window.getSelection(). However, the browser selection API is different for IE. If I were to use a textarea instead (for interacting with the selection api), is there a uniform API across the browsers? Then I would need to overlay a DIV on top of this to display the styled text, and presumably I'd need to manage the cursor etc... Basically I want a rich text editor - but without editing. Does anyone have any advice on the best way to go about this, which is quick, simple and cross browser compatible. I don't want to spend ages reinventing the wheel... (If anyone's interested - this is for an online xml editor. I capture the users selection on a html version of the xml doc and then send the selection offsets info to the server, where the real xml doc gets marked up). Kind Regards Swami

• How do you detect when the Flowplayer has started playing the video?

  - by Alex

  Hi. I'm using the Flowplayer Flash video player to play MP4 videos inside an AnythingSlider. I need to detect when the user has clicked the start button on the video so to stop the slideshow and allow the user to view the video. I've tried using this code just to get an alert box but it doesn't do anything (the code is at the end of the page, before the closing </body> tag): <script type="text/javascript"> $f("player","global/js/flowplayer/flowplayer-3.1.5.swf",{ onStart: function(clip) { alert('player started'); } }); </script> The Flowplayer is implemented as part of the html5media library, which automatically detects whether the browser can handle the <video> tag; if not, it replaces the anchor tag below with the Flowplayer: <video id="vid" width="372" height="209" poster="global/vid/bbq-poster.jpg" controls preload> <source id="videoSource" src="global/vid/BBQ_Festival.mp4" type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"' onerror="fallback(this.parentNode)" ></source> <a href="global/vid/BBQ_Festival.mp4" style="display:block;width:372px;height:209px; padding-left:5px; " id="player"> </a> </video> So the $f() function call is in a JavaScript block at the end of the page, to give the player a chance to load correctly. What am I doing wrong? Thanks.

• jquery image fading with tabs

  - by StealthRT

  Hey all, i am trying my best to figure out how to go about doing this: I have 2 tabs. When the page loads tab1 is selected automatically. This shows the tab as 1.0 transparency while tab2 stays at 0.7. Once the user clicks on tab2, tab1 goes to 0.7 transparency and tab2 goes to 1.0. However, i can not seem to get it to do that! Here is my code: <script type="text/javascript"> function checkTab(theTab) { $('#tab1').fadeTo(250, 0.70); $('#tab2').fadeTo(250, 0.70); if ($("#tabActive").val() == theTab) { $(theTab).fadeTo(250, 1); } } $(document).ready(function() { $('#tab1').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab1')}); $('#tab2').hover(function() {$(this).fadeTo(250, 1)}, function() {checkTab('#tab2')}); $('#tab2').fadeTo(250, 0.70); $('#tabActive').val('tab1'); }); </script> <li class="stats"><img src="images/Stats.png" name="nav1" width="70" height="52" id="tab1" onclick="$('#tabActive').val('tab1');" /></li> <li class="cal"><img src="images/cal.png" name="nav1" width="70" height="52" id="tab2" onclick="$('#tabActive').val('tab2');" /></li> <input name="tabActive" id="tabActive" type="text" /> Any help would be great! :) David

• can javascript process binary data?

  - by Johnny

  admit me describe my questions in situation-oriented way: assume IE is still the dominate web browser(the firefox have document for binary processing): the XMLHttpRequest.responseText or XMLHttpRequest.responseXML in ie desire txt or xml/xhtml/html,but what about the server response the xmlHttprequest whith MIME TYPE application/octet ? would the response string all little than 256 ?(every char of that string < 256), thanks very much for a straight answer, i have no webserver env,so i don't know how to test it out. because use txt or xml have a issue of character set encode, and i don't know how to process #[[[CDDATA node of one encoded xml(ex : utf-8,ascii,gb18030) with javascript, when i getNodeText, does the docObj return me byte or decoded char ? if it was decoded char which according to the header indicated charSet in the httpresponse , it would be all wrong. to avoid mess up with charSet ,i would like the server to response octet data and force strings data to be encoded as utf-8 but another charSet in the binary format. if the response is octal, so i guess the browser would not try to decode the response"txt" does this weird? or miss understanding the fundamental things? EDIT: I believe the question is asking this: Can Javascript safely process strings that aren't encoded in Unicode? What are the problems with trying to do so? EDIT: no no no , i means if http-header: content-type is "application/octet" , would the ie try to decoded it as (16bits Unicode | ie local setting charset ) when i get XMLHttpRequestobj.responseText use javascript ? or it(ie) just wrap every single byte of the response body as a javascript string, then every char in that string little than or equal 256 (char<=256), am i talking Mars language? sadly, if i were Marsizen,i would come as tourist without fuzzy questions. however i am in a country which share at least one property with Mars : RED

• Why is there a time lag when trying to change the text on a button in IE using JQuery?

  - by Deane

  I have some Ajax that runs on a button click. Sometimes it takes a few seconds to return, so I wanted a visual clue to the user that the browser was doing something. So, I have this: $('#SubmitButton').attr("value", "Working..."); $('#SubmitButton').attr("disabled", true); //Synchronous Ajax call goes here $('#SubmitButton').attr("value", "Submit"); $('#SubmitButton').attr("disabled", false); As you can see, it changes the text on the button, and disables it. When the Ajax call comes back (it's synchronous, remember), the button changes back. In Firefox, this works great. In IE, it's...odd. It doesn't run the code in order. It doesn't change the text of the button and launches right into the Ajax call. The browser blocks with the Submit active and saying "Submit." Right after the Ajax comes back, the button quickly flashes "Working..." then back to Submit." So, for some reason, IE isn't changing the text of the button until after the Ajax call, even though the code for it is before the Ajax call. It's acting like this: //Synchronous Ajax call goes here $('#SubmitButton').attr("value", "Working..."); $('#SubmitButton').attr("disabled", true); $('#SubmitButton').attr("value", "Submit"); $('#SubmitButton').attr("disabled", false); Again, this works perfectly in Firefox. But in IE, there's some kind of...lag?

• How to disable firefox's form auto completion without change events?

  - by Dmitriy Likhten

  So firefox has a nifty mechanism which will try to autocomplete values in fields when a page is reloaded or the back button is used. Which is great and all except when you have something like a drop-down which when set to a value modifies the page using ajax. What winds up happening is that the browser reloads the page, the drop down is pre-filled with the remembered value, and then no change event is fired when the dom is ready. And therefore the change handlers attached don't fire and thus the page does not update. Is there a good way to "fix" this behavior so that it works for the user as expected: a) We do want the browser to auto-complete because that is a good user experience. b) Still want that onchange event firing. The only thing I can think of doing at the moment is to add an on-ready event to the document which has javascript pre-populated with initial values in the form, when the document loads the javascript will check the pre-populated values and if not matching what is in the input will trigger the change handlers. Anyone have a better solution? Is there a lib that does this already? (Using Rails 2.3.5 + jQuery)

• Building a TriggerField with PopUp Window

  - by umit_alba

  Hi! I built a triggerField and when i press at it, i want to have a popup, that is appended to the button in the triggerfield(so when i click anywhere else it shall disappear and it shall pop out up to the button when i click at the button just like a datepicker-popup) I somehow managed to do something like that with an Ext.window but the offset and postion doesnt match. This all should be contained in a row editor. my Code: new Ext.grid.GridPanel({ store: Store, region:'center', height:150, //minWidth:700, autoScroll:true, listeners:{}, plugins:[new Ext.ux.grid.RowEditor()], tbar: [{ iconCls: 'icon-user-add', text: ' hinzufügen', handler: function(){ alert("abc"); } },{ ref: '../removeBtn', iconCls: 'icon-user-delete', text: 'löschen', disabled: true, handler: function(){ editor.stopEditing(); var s = grid.getSelectionModel().getSelections(); for(var i = 0, r; r = s[i]; i++){ store.remove(r); } } }], columns: [{ header: 'Monate', dataIndex: 'MONAT', width: 50, sortable: true, editor: new Ext.form.TriggerField({"id":"EditorMonate",items:[], "onTriggerClick":function(thiss){ if(!Ext.getCmp("autoWMonate")){ var monate=new Ext.Window({"x":Ext.getCmp("EditorMonate").x,closeAction:"hide",width:275,id:"autoWMonate",layout:"table",layoutConfig: {columns: 10}}); var text; for(var mon=1;mon<13;mon++){ text=mon; mon?mon:text="0"; if(mon<10) text="0"+mon; monate.items.add( new Ext.Button({cls:"x-btn",value:parseInt(text),selected:true,"text":text,id:text }}}));} } Ext.getCmp("autoWMonate").hidden?Ext.getCmp("autoWMonate").show():Ext.getCmp("autoWMonate").hide(); }}) } }] })

• Strange layout behaviour

  - by andrii

  I am a little bit confused. Here is an small web page. There are two main div-s: top and mainBlock. First contain image. The problem is that firebug shows that div#top's height is equal to 0 and because of that the next div mainBlock moves up. If I would delete this peace of code: div#logo{ float: left; } everything will start working fine and div#mainBlock will be below the div#top. Could you, please, explain me how it works and how to avoid this in proper way? Here is my code: <!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> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <title>Paralab - Website &amp; interface design, web apps development, usability</title> <style text="text/css"> html, body{ } div#logo{ float: left; } #top{ width: 100%; } #mainBlock{ width:100%; } </style> </head> <body> <div id="top"> <div id="logo"> <img alt="logo" src="img/logo.png" /> </div> </div> <div id="mainBlock"> Contact Us </div> </body> </html>

• Using JQuery to traverse DOM structure, finding a specific <table> element located after HTML 'comme

  - by Shadow

  I currently have a website source code (no control over the source) which contains certain content that needs to be manipulated. This would be simple on the surface, however there is no unique ID attribute on the tag in question that can uniquely identify it, and therefore allow for further traversal. Here is a snippet of the source code, surrounding the tag in question. ... <td width="100%"> <!--This table snaps the content columns(one or two)--> <table border="0" width="100%"> ... Essentially, the HTML comment stuck out as an easy way to gain access to that element. Using the JQuery comment add-on from this question, and some help from snowlord comment below, I have been able to identify the comment and retrieve the following output using the 'dump' extension. $('td').comments().filter(":contains('This table snaps the content columns(one or two)')").dump(); returns; jQuery Object { 0 = DOMElement [ nodeName: DIV nodeValue: null innerHTML: [ 0 = String: This table snaps the content columns(one or two) ] ] } However I am not sure how to traverse to the sibling element in the DOM. This should be simple, but I haven't had much selector experience with JQuery. Any suggestions are appreciated.

• Anchor HTML DIV tag to right of screen

  - by Phillip

  Hello, I have a site that has 2 DIV tags, one floats left the other floats right. The left DIV contains text for the page, the other DIV is used to display a video. When I have text in the left DIV that fits the entire width of the screen the video shows up where I want it. However, a few pages have very little text and cause the video to show up in the right-center of the screen. I want to anchor this DIV to the right of the screen regardless of how much text is shown. I don't seem to get this problem in lower resolutions, it occurs more in the higher resolutions (such as 1280x1024). You can see an example on these pages: http://www.quilnet.com/TechSupport.aspx - Positions the right DIV where I want it regardless of the resolution. http://www.quilnet.com/ContactUs.aspx - Makes the right DIV closer to the center in higher resolutions. I want it in the position of the page TechSupport.aspx. I am trying to refrain from using the width parameter because I want it to be resolutionally compliant. I don't want my viewers to have to move a scroll bar left and right. Any ideas? Thanks!

• python gui events out of order

  - by dave

  from Tkinter import * from tkMessageBox import * class Gui: def __init__(self, root): self.container = Frame(root) self.container.grid() self.inputText = Text(self.container, width=50, height=8) self.outputText = Text(self.container, width=50, height=8, bg='#E0E0E0', state=DISABLED) self.inputText.grid(row=0, column=0) self.outputText.grid(row=0, column=1) self.inputText.bind("<Key>", self.translate) def translate(self, event): input = self.inputText.get(0.0, END) output = self.outputText.get(0.0, END) self.outputText.config(state=NORMAL) self.outputText.delete(0.0, END) self.outputText.insert(INSERT, input) self.outputText.config(state=DISABLED) showinfo(message="Input: %s characters\nOutput: %s characters" % (len(input), len(input))) root = Tk() #toplevel object app = Gui(root) #call to the class where gui is defined root.mainloop() #enter event loop Working on a gui in tkinter I'm a little confused as to the sequence the event handlers are run. If you run the above code you'll hopefully see... 1) Editing the text widget triggers the event handler but it seems to fire it off without registering the actual change, 2) Even when the text widget is cleared (ie, keep pressing BackSpace) it still seems to have a one character length string, 3) The output widget only receives its update when the NEXT event trigger is fired despite the fact the data came on the previous event. Is this just how bindings work in tkinter or am i missing something here? The behaviour i would like when updating the input widget is: 1) Show the change, 2) Enter event handler, 3) Update output widget, 4) Show message box.

• Set form MinWidth and MinHeight based on child property

  - by Jon Mitchell

  I'm writing an application in WPF using the MVVM pattern. In my application I've got an IPopupWindowService which I use to create a popup dialog window. So to show a ViewModel in a popup window you'd do something like this: var container = ServiceLocator.Current.GetInstance<IUnityContainer>(); var popupService = container.Resolve<IPopupWindowService>(); var myViewModel = container.Resolve<IMyViewModel>(); popupService.Show((ViewModelBase)myViewModel); This is all well and good. What I want to do is be able to set the MinHeight and MinWidth on the View bound to myViewModel and have the popup window use those settings so that a user cannot make the window smaller than its contents will allow. At the moment when the user shrinks the window the contents stops resizing but the window doesn't. EDIT: I map my Views to my ViewModels in ResourceDictionarys like so: <DataTemplate DataType="{x:Type ViewModels:MyViewModel}"> <Views:MyView /> </DataTemplate> And my popup view looks like this: <Window x:Class="TheCompany.Cubit.Shell.Views.PopupWindowView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" SizeToContent="WidthAndHeight" WindowStartupLocation="CenterOwner"> <DockPanel x:Name="panelContent"> <StackPanel HorizontalAlignment="Right" DockPanel.Dock="Bottom" Orientation="Horizontal" Visibility="{Binding RelativeSource={RelativeSource AncestorType=Window},Path=ButtonPanelVisibility}"> <Button Width="75" IsDefault="True" x:Uid="ViewDialog_AcceptButton" Click="OnAcceptButtonClick" Margin="4">OK</Button> <Button Width="75" IsCancel="True" x:Uid="ViewDialog_CancelButton" Click="OnCancelButtonClick" Margin="0,4,4,4">Cancel</Button> </StackPanel> <ContentPresenter Content="{Binding}" /> </DockPanel>

• How to optimize Conway's game of life for CUDA?

  - by nlight

  I've written this CUDA kernel for Conway's game of life: global void gameOfLife(float* returnBuffer, int width, int height) { unsigned int x = blockIdx.x*blockDim.x + threadIdx.x; unsigned int y = blockIdx.y*blockDim.y + threadIdx.y; float p = tex2D(inputTex, x, y); float neighbors = 0; neighbors += tex2D(inputTex, x+1, y); neighbors += tex2D(inputTex, x-1, y); neighbors += tex2D(inputTex, x, y+1); neighbors += tex2D(inputTex, x, y-1); neighbors += tex2D(inputTex, x+1, y+1); neighbors += tex2D(inputTex, x-1, y-1); neighbors += tex2D(inputTex, x-1, y+1); neighbors += tex2D(inputTex, x+1, y-1); __syncthreads(); float final = 0; if(neighbors < 2) final = 0; else if(neighbors 3) final = 0; else if(p != 0) final = 1; else if(neighbors == 3) final = 1; __syncthreads(); returnBuffer[x + y*width] = final; } I am looking for errors/optimizations. Parallel programming is quite new to me and I am not sure if I get how to do it right. The rest of the app is: Memcpy input array to a 2d texture inputTex stored in a CUDA array. Output is memcpy-ed from global memory to host and then dealt with. As you can see a thread deals with a single pixel. I am unsure if that is the fastest way as some sources suggest doing a row or more per thread. If I understand correctly NVidia themselves say that the more threads, the better. I would love advice on this on someone with practical experience.

  Hi Guy's NSString* appendString=@""; appendString = [appendString stringByAppendingString:@"<body>"]; appendString =[appendString stringByAppendingString:@"<table background='footer.png' width='320' height='45' style='background-repeat:no-repeat'>"]; appendString =[appendString stringByAppendingString:@"<tr>"]; appendString =[appendString stringByAppendingString:@"<td align='left' width='57' height='31' style='padding: 6px 0 0 0' ><a href='/map/'><img src='details_Back.png'/></a></td>"]; appendString =[appendString stringByAppendingString:@"<td align='left' valign='middle' style='padding: 0 0 0 65px; font-family:Helvetica; font-size:21px ; font-weight:bold ; color:#FFF'>Details</td>"]; appendString =[appendString stringByAppendingString:@"</tr>"]; appendString =[appendString stringByAppendingString:@"</table>"]; appendString =[appendString stringByAppendingString:@"<br>"]; returnString = [returnString stringByReplacingOccurrencesOfString:@"<body>" withString:appendString]; printf("\n return string :%s",[returnString UTF8String]); [myWebView loadHTMLString:returnString baseURL:[NSURL URLWithString:@"http://abc.api.abcdefg.com/"]]; here in the above code the footer.png and details_back.png are the local images stored in my resource folder. Here the problem is I am gettin the background image from the server link I had passed to the webview as baseurl but the images footer.png and details_back.png which were stored in resource is not displayed. if I use the resource bundle as the baseurl then I am not displayed the background image from the server link. Can anyone please give me the suggestions to get rid of rid of this problem. thanks to all guy's, Monish.

  - by IamStalker

  here is my animation class that i have taken from Udnic - thanks m8, but i'm using it "not from closed position but from opened" and it's jumps and not behaving correctly. what should i do? public class ExpandAnimation extends Animation { private View mAnimatedView; private LinearLayout.LayoutParams mViewLayoutParams; public int mMarginStart, mMarginEnd; private boolean mIsVisibleAfter = false; private boolean mWasEndedAlready = false; private ImageView mImageView; /** * Initialize the animation * @param view The layout we want to animate * @param duration The duration of the animation, in ms */ public ExpandAnimation(View view, int duration, ImageView imageView) { setDuration(duration); mImageView = imageView; mAnimatedView = view; mViewLayoutParams = (LinearLayout.LayoutParams) view.getLayoutParams(); mMarginStart = mMarginEnd = 0; // decide to show or hide the view mIsVisibleAfter = (view.getVisibility() == View.VISIBLE); //mIsVisibleAfter = (mViewLayoutParams.bottomMargin == 0); mMarginStart = mViewLayoutParams.bottomMargin; if(mMarginStart != 0) mMarginStart = 0 - view.getHeight(); mMarginEnd = (mMarginStart == 0 ?

• Segmenting and masking all shades of red from an image using opencv

  - by vrinda

  I am trying to segment all shades of red form an image using hue saturation values and use InRangeS function to create a mask which should have all red areas whitened and all others blacked(a new 1 channel image). Thwn Inpaint them to kind of obscure the segmented portions. My code is as given. However I am unable to get an output image, it doesnt segment the desired color range. Any pointers on my approach and why it isnt working. ? using namespace std; int main() { IplImage *img1=cvLoadImage("/home/techrascal/projects/test1/image2.jpeg"); //IplImage *img3; IplImage *imghsv; IplImage *img4; CvSize sz=cvGetSize(img1); imghsv=cvCreateImage(sz,IPL_DEPTH_8U,3); img4=cvCreateImage(sz,IPL_DEPTH_8U,1); int width = img1->width; int height = img1->height; int bpp = img1->nChannels; cvNamedWindow("original", 1); cvNamedWindow("hsv",1); cvNamedWindow("Blurred",1); int r,g,b; // create inpaint mask: img 4 will behave as mask cvCvtColor(img1,imghsv,CV_BGR2HSV); CvScalar hsv_min = cvScalar(0, 0, 0, 0); CvScalar hsv_max = cvScalar(255, 0, 0, 0); //cvShowImage("hsv",imghsv); cvInRangeS( imghsv, hsv_min, hsv_max, img4 ); cvInpaint(img1, img4, img1, 3,CV_INPAINT_NS ); cvShowImage("Blurred",img1); cvReleaseImage(&img1); cvReleaseImage(&imghsv); cvReleaseImage(&img4); //cvReleaseImage(&img3); char d=cvWaitKey(10000); cvDestroyAllWindows(); return 0;}

• Getting Public Info about Location in Facebook Graph API

  - by Allan Deamon

  I need to get the living city of each person in a group. Including people that are not my friends. In the browser seeing facebook profile of some unknown person, they show "lives in ...", if this is set as public information. They include the link to the city object with the city id in the link. That's all that I need. But, using a facebook app that I created to use the facebook graph api, this information is not public. I can only get the user propriety 'location' from friends of my that I have permission to see it. I gave ALL the possible permissions to my app. In the api explorer, when I use it as REST, they show few informations about someone not friend of mine. https://developers.facebook.com/tools/explorer/ Also in the api explorer, when I use the FQL, it didn't works. This query works, returning the JSON with the data: SELECT uid, name FROM user WHERE username='...'; But this other query doesn't work: SELECT uid, name, location FROM user WHERE username='...'; They return a json with a error code: { "error": { "message": "(#602) location is not a member of the user table.", "type": "OAuthException", "code": 602 } } I asked for ALL the permissions options in the token. And I can get this info in the browser version of the facebook. But how can I get it with the API ?
