  • Modify shell script to monitor/ping multiple ip addresses

    - by Alex
    Alright so I need to constantly monitor multiple routers and computers, to make sure they remain online. I have found a great script here that will notify me via growl(so i can get instant notifications on my phone) if a single ip cannot be pinged. I have been attempting to modify the script to ping multiple addresses, with little luck. I'm having trouble trying to figure out how to ping a down server while the script keeps watching the online servers. any help would be greatly appreciated. I haven't done much shell scripting so this is quite new to me. Thanks #!/bin/sh #Growl my Router alive! #2010 by zionthelion73 [at] gmail . com #use it for free #redistribute or modify but keep these comments #not for commercial purposes iconpath="/path/to/router/icon/file/internet.png" # path must be absolute or in "./path" form but relative to growlnotify position # document icon is used, not document content # Put the IP address of your router here localip=192.168.1.1 clear echo 'Router avaiability notification with Growl' #variable avaiable=false com="################" #comment prefix for logging porpouse while true; do if $avaiable then echo "$com 1) $localip avaiable $com" echo "1" while ping -c 1 -t 2 $localip do sleep 5 done growlnotify -s -I $iconpath -m "$localip is offline" avaiable=false else echo "$com 2) $localip not avaiable $com" #try to ping the router untill it come back and notify it while !(ping -c 1 -t 2 $localip) do echo "$com trying.... $com" sleep 5 done echo "$com found $localip $com" growlnotify -s -I $iconpath -m "$localip is online" avaiable=true fi sleep 5 done

  • Block element, horizontal center aligned and minimum width possible

    - by Nazgulled
    Hi, I'm trying to have this block element to be horizontally aligned in the middle but at the same time I would like the width to be the minimum possible for the contents inside. But I don't think it's possible or I'm not able to do it myself... a#button-link { background: url("images/button-link.png") no-repeat scroll center left; margin: 12px auto 0 auto; display: block; width: 125px; height: 32px; line-height: 32px; padding-left: 35px; font-weight: bold; } This is my current code... The idea behind this is that the text for that tag could be slightly bigger or smaller depending on the user language and how much characters the same sentence has for that specific user's language. There's no way I can control but I still would like to have this element horizontally aligned to center. Is this possible with CSS?

  • jQuery server ping slowly but surely filling memory?

    - by danspants
    I use the following piece of code to test if our server is running whilst the user is in a page. I've also started adding other functions that grab small amounts of data that are constantly changing and are to be relayed to the user (Files waiting for download, messages, reports etc). I've noticed recently that if I leave any page open (all pages contain the same function), the browser takes up more and more system memory which I can only attribute to this regular task (overnight it reached 1.6 gb). Is there some way of clearing out the data that is being accumulated? Is this normal behaviour? As far as i can tell, every time I call the function it should overwrite the previously retrieved data? function testServer(){ jQuery.ajax({ type:"HEAD", url:"/media/d_arrow_blue.png", error: function(msg) { jQuery.jGrowl("Server Disconnected"); } }); //retrieves count of files awaiting download - move to seperate function jQuery.get("/get_files/",{"type":"count"},function(data) { jQuery("#downloadList").children("div").text(data); }); }; jQuery().doTimeout(6000,function() { testServer(); return true; });

  • Can Internet Explorer bind events to absolute positioned elements ?

    - by mark
    Can Internet Explorer bind events to absolute positioned elements ? I can't bind a "click" to an element that is overlapping another. Have tried loads of different ways, here a few tests that don't work in IE: //version 1: $(".classHolder").click(function(){ alert( $(this).html() ); }); //version 2: $(".classHolder").each(function(){ $(this).click(function(){ alert( $(this).html() ); }); }); //version 3: $("#id3").click(function(){ alert( $(this).html() ); }); //version 4: $("#id3").click(function(){ alert( $(this).html() ); }); $("#id3").trigger("click"); // in all trials I tested with and without: // $("img").unbind(); // $("div").unbind(); // just to make sure no "ghost" events were bind into the elements but no success. // replace all [ for < , and all ] for [html] [head] [script src="http://code.jquery.com/jquery-latest.js"][/script] [script type="application/javascript"] $(document).ready(function(){ $("#id3").click(function(){ alert( $(this).html() ); }); $("#id3").trigger("click"); }); [/script] [/head] [body] [div id="id1" style="position:relative;"] [img id="id2" src="http://www.google.co.uk/intl/en_com/images/srpr/logo1w.png" style=";z-index:-1;"/] [div id="id3" class="classHolder" style="position:absolute;border:2px solid red;left:0px;top:0px;width:70px;height:70px;z-index:1002;"]G[/div] [div id="id4" class="classHolder" style="position:absolute;border:2px solid red;left:210px;top:0px;width:25px;height:70px;z-index:1001;"]L[/div] asd asdf asdfg [/div] [/body] [/html]

  • How do you ensure a <td> is exactly 200px tall?

    - by George Edison
    I have a table with an image inside: <table style="border: 3px solid rgb(0, 0, 0); width: 800px; background-color: rgb(255, 255, 255); margin-left: auto; margin-right: auto; border-collapse: collapse;"> <tbody> <tr> <td style="text-align: center; padding: 0px; margin: 0px;"><img style="width: 800px; height: 200px; border: 0px;" alt="Logo" src="logo.png"> </td> </tr> </tbody> </table> No matter what I do, there is still a little sliver of white at the bottom of the image. A quick check with Chrome's Inspector reveals that the td has a height of 204px! How can I force the td to be the same height as the image? As you can see above, I've tried all sorts of things...

  • Downloading jQuery UI: Ok, so what part of this mess do I copy to the server?

    - by Martha
    From the "should be simple, but..." files: Trying to get started with jQuery UI. Went to the site, used their custom builder thingy to assemble the parts I need, made myself a custom theme using the Theme Roller, downloaded the zip file thus produced, unzipped it on my local drive. Ok, so I have 37 folders, 311 files, and a total of 2.4 MB. Ain't no way in hell all this is going on the server. What parts do I need to put there? 'css' 'custom-theme': jquery-ui-1.8.custom.css, 'images' subfolder with 12 .png images 'development-bundle' 'demos': demos.css, index.html, plus 18 subfolders, but I'm guessing "not needed" 'docs': 17 .html files, but again, I'm guessing "not needed" 'external': 4 .js files, one .css 'themes': 'base' and 'custom-theme' subfolders, each with 8 or 9 .css files and an 'images' subfolder with about a dozen images 'ui': 25 .js files, an 'i18n' subfolder with 53 .js files, and a 'minified' subfolder with 24 .js files 'js': jquery-1.4.2.min.js and jquery-ui-1.8.custom.min.js Also, the file structure. Our server is set up something like this: root admin (administrative tools) css forms (the gist of the site lives here) images include (asp code snippets that are used by multiple pages) js (just a few things right now, like an ancient wheezing spelling checker) As far as I can tell, the jQuery css files assume that (1) each theme is in its own folder, and (2) each folder has its own images subfolder. How can I convince it otherwise? i.e. put the necessary .js files in the 'js' folder, the .css files in the 'css' folder, and the images in the 'images' folder?

  • UIViewTableCell didSelectRowAtIndexPath is calling but not pushing a view controller

    - by Kenneth
    Hi guys, so im having a UIViewController view with a UITableView. So the UIViewController class name is SelectionScreen. The UITableView class name is SelectionScreenTable. Picture: http://img717.imageshack.us/i/screenshot20100609atpm0.png/ I have declared a UITableView *selectionTable in SelectionScreen class and connected it to the xib file of the SelectionScreen what the problem is , is that when i click a row in the table,it stays selected as highlighted blue, it calls the didSelectRowAtIndexPath (checked with NSLog) but not pushing a new view which is called(GraphView). This is the code which i use to call the new controller WHICH WORKS with a normal button GraphView *aSelectionScreenViewController = [[GraphView alloc] initWithNibName:@"GraphView" bundle:nil]; [self presentModalViewController:aSelectionScreenViewController animated: YES]; [aSelectionScreenViewController release]; I searched around and found that I need to set a delegate for the table in the UITableView class itself on the viewload tableview.delegate = self; or self.tableview.delegate = self; But it was not working. the controller was still not being pushed, and yes i have checked the controller is not nil as i tried it with a simple button. So i was thinking whether i should set the delegate of the UITableView at the UIViewController instead, so i tried this code selectionTable.delegate = selectionTable.self; but obviously it did not work =\, it messed up the whole UITableView and caused all the cells to be its predefined settings. So does anybody have any idea on how i can get it to work.

  • How to efficiently show many Images? (iPhone programming)

    - by Thomas
    In my application I needed something like a particle system so I did the following: While the application initializes I load a UIImage laserImage = [UIImage imageNamed:@"laser.png"]; UIImage *laserImage is declared in the Interface of my Controller. Now every time I need a new particle this code makes one: // add new Laserimage UIImageView *newLaser = [[UIImageView alloc] initWithImage:laserImage]; [newLaser setTag:[model.lasers count]-9]; [newLaser setBounds:CGRectMake(0, 0, 17, 1)]; [newLaser setOpaque:YES]; [self.view addSubview:newLaser]; [newLaser release]; Please notice that the images are only 17px * 1px small and model.lasers is a internal array to do all the calculating seperated from graphical output. So in my main drawing loop I set all the UIImageView's positions to the calculated positions in my model.lasers array: for (int i = 0; i < [model.lasers count]; i++) { [[self.view viewWithTag:i+10] setCenter:[[model.lasers objectAtIndex:i] pos]]; } I incremented the tags by 10 because the default is 0 and I don't want to move all the views with the default tag. So the animation looks fine with about 10 - 20 images but really gets slow when working with about 60 images. So my question is: Is there any way to optimize this without starting over in OpenGl ES? Thank you very much and sorry for my english! Greetings from Germany, Thomas

  • How to run javascript on an ajax output?

    - by WAC0020
    I am using jquery-ui tabs and ajax to load the content of the tabs. Here is my javascript: $(document).ready(function() { $("#tabs").tabs({ fx: { opacity: 'toggle' } }); $('.hd_item').hover(function() { //Display the caption $(this).find('span.hd_caption').stop(false,true).fadeIn(600); }, function() { //Hide the caption $(this).find('span.hd_caption').stop(false,true).fadeOut(400); }); }); When the user clicks on the tab is will load the content.php via ajax. The output of the ajax is: <li class="hd_item"> <img title="Backyard Brawl" alt="Backyard Brawl" src="games/normal_icons/1844.png" id="hd_icon"> <span class="hd_caption"> <h1>Backyard Brawl</h1> <p id="hd_description">In this game you pick a player and beat each other up with ...</p> <p id="hd_stat">Added: <br>2009-12-14</p><a href="/dirtpilegames/index.php?ground=games&amp;action=play&amp;dig=backyard-brawl">PLAY</a> </span> </li> The problem that I am having is the javascript is not working on the ajax output.

  • Two objects with dependencies for each other. Is that bad?

    - by Kasper Grubbe
    Hi SO. I am learning a lot about design patterns these days. And I want to ask you about a design question that I can't find an answer to. Currently I am building a little Chat-server using sockets, with multiple Clients. Currently I have three classes. Person-class which holds information like nick, age and a Room-object. Room-class which holds information like room-name, topic and a list of Persons currently in that room. Hotel-class which have a list of Persons and a list of Rooms on the server. I have made a diagram to illustrate it (Sorry for the big size!): http://i.imgur.com/Kpq6V.png I have a list of players on the server in the Hotel-class because it would be nice to keep track of how many there are online right now (Without having to iterate through all of the rooms). The persons live in the Hotel-class because I would like to be able to search for a specific Person without searching the rooms. Is this bad design? Is there another way of achieve it? Thanks.

  • Using HTML5 on iPhone - cannot pause

    - by Ariel
    Hey guys, I was wondering whether anyone has tried to use the new tag that comes with HTML5 on the iPhone. Specifically, I didn't manage to make the pause() command to work. Below is a portion of the page. As you can see, I'm trying to pause the video 10sec after it started. It works on Safari on a Mac btw. Has anyone managed to make this work? <head> <javascript language="JavaScript"> function timeUpdate() { var myVideo = document.getElementsByTagName('video')[0]; var time = myVideo.currentTime; if (time > 10) { myVideo.pause(); } } function addListeners() { var myVideo = document.getElementsByTagName('video')[0]; myVideo.addEventListener('timeupdate',timeUpdate,false); } </script> </head> <body onload="addListeners()"> <video controls src="resources/bb_poor_cinderella_512kb.mp4" poster="resources/background.png"> Video tag not supported! </video> </body> Thanks, Ariel

  • How to move/drag multiple images with CALayer???

    - by gbf.sara
    I have more than 10 images in screen and i want to move each image using CALayer concept. While am trying to move first image,its working. Even when i drag my second image also, its working. But after that when i get back to first image and when i try to move , am struck up. its not working. I dono where it went wrong. Here's ma code //Assigning Layer to UIImage// layer = [CALayer layer]; UIImage *image1 = [UIImage imageNamed:[NSString stringWithFormat:@"%@_thumb.png",[tiv imageName]]]; layer.contents = (id)image1.CGImage; layer.position=CGPointMake(200,200); layer.frame = CGRectMake(110, 180, 100, 100); [self.view.layer addSublayer:layer]; [layer needsDisplay]; [self.view.layer needsDisplay]; [layer needsLayout]; //Here i try to move my image// - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesMoved:touches withEvent:event]; NSArray *allTouches = [touches allObjects]; int count = [allTouches count]; if (count == 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:0] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } if (count > 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:-1] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } } Also ive planned to use single CALayer for multiple images.. When i click an image, it should be placed in that CALayer and when i click another, the same CALayer should take the latter one. So tat whenever i drag an image it should move(no matter how many images r there) . Do u think this concept will work out or is there any other idea??? My concept may seems to be a basic one. Am new to this environment n so kindly help me..

  • NotFoundException in layout editor for Android?

    - by borg17of20
    I'm trying to extend a RelativeLayout object and include an embedded SurfaceView object that uses a png file in my /res/drawable folder as its background but I keep getting an error in the XML Layout editor. See the following code: public class StopMotionRelativeLayout extends RelativeLayout { private Context myContext; private SurfaceView surfaceView1; private BitmapFactory.Options myBitmapOptions; private final android.view.ViewGroup.LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, android.view.ViewGroup.LayoutParams.FILL_PARENT); public StopMotionRelativeLayout(Context context, AttributeSet attrs) { super(context, attrs); myContext = context; this.setBackgroundColor(Color.GREEN); //init images surfaceView1 = new SurfaceView(myContext,attrs); surfaceView1.setVisibility(View.INVISIBLE); this.addView(surfaceView1, params); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); myBitmapOptions = new Options(); myBitmapOptions.outWidth = widthMeasureSpec; myBitmapOptions.outHeight = heightMeasureSpec; surfaceView1.setBackgroundDrawable(new BitmapDrawable(BitmapFactory.decodeResource(this.myContext.getResources(), R.drawable.golf1, myBitmapOptions))); } } I get the following error: NotFoundException: Could not find drawable resource matching value 0x7F020002 (resolved name: golf1) in current configuration. I have seen this type of error may times now and it always happens when I try to load something from a resource file via code and not XML. Curiously, this error does not stop me from compiling the app, and the app runs without error in the emulator. I'd like to get back the use of my layout editor though... Please help. UPDATE: Here is the layout XML <?xml version="1.0" encoding="utf-8"?> <com.games.test.StopMotionRelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> </com.games.test.StopMotionRelativeLayout>

  • How to adjust size of programatically created Bitmap to match text drawn on it?

    - by TooFat
    I have the following .ashx page that takes some query string parameters and returns a bitmap with the specified text written on it. The problem I have is that I am currently just manually setting the initial size of the bitmap at 100 X 100 when what I really want is to have the bitmap be just big enough to include all the text that was written to it. How can I do this? public void ProcessRequest (HttpContext context) { context.Response.ContentType = "image/png"; string text = context.Request.QueryString["Text"]; //set FontName string fontName; if (context.Request.QueryString["FontName"] != null) { fontName = context.Request.QueryString["FontName"]; } else { fontName = "Arial"; } //Set FontSize int fontEms; if (context.Request.QueryString["FontSize"] != null) { string fontSize = context.Request.QueryString["FontSize"]; fontEms = Int32.Parse(fontSize); } else { fontEms = 12; } //Set Font Color System.Drawing.Color color; if (context.Request.QueryString["FontColor"] != null) { string fontColor = context.Request.QueryString["FontColor"]; color = System.Drawing.ColorTranslator.FromHtml(fontColor); context.Response.Write(color.ToString()); } else { color = System.Drawing.Color.Red; } using (System.Drawing.Text.PrivateFontCollection fnts = new System.Drawing.Text.PrivateFontCollection()) using (System.Drawing.FontFamily fntfam = new System.Drawing.FontFamily(fontName)) using (System.Drawing.SolidBrush brush = new System.Drawing.SolidBrush(color)) using (System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(100, 100)) { using (System.Drawing.Font fnt = new System.Drawing.Font(fntfam, fontEms)) { fnts.AddFontFile(System.IO.Path.Combine(@"C:\Development\Fonts\", fontName)); System.Drawing.Graphics graph = System.Drawing.Graphics.FromImage(bmp); graph.DrawString(text, fnt, brush, new System.Drawing.Point(0, 0)); string imgPath = System.IO.Path.Combine(@"C:\Development\MyPath\Images\Text", System.IO.Path.GetRandomFileName()); bmp.Save(imgPath); context.Response.WriteFile(imgPath); } } }

  • Im Stumped, Why is UIImage\Texture2d memory not being freed

    - by howsyourface
    I've been looking everywhere trying to find a solution to this problem. Nothing seems to help. I've set up this basic test to try to find the cause of why my memory wasn't being freed up: if (texture != nil) { [texture release]; texture = nil; } else { UIImage* ui = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"image" ofType:@"png"]]; texture = [[Texture2D alloc] initWithImage:ui]; } Now i would place this in the touches began and test by monitoring the memory usage using intstruments at the start (normally 11.5 - 12mb) after the first touch, with no object existing the texture is created and memory jumps to 13.5 - 14 However, after the second touch the memory does decrease, but only to around 12.5 - 13. There is a noticeable chunk of memory still occupied. I tested this on a much larger scale, loading 10 of these large textures at a time The memory jumps to over 30 mb and remains there, but on the second touch after releasing the textures it only falls to around 22mb. I tried the test another time loading the images in with [uiimage imagenamed:] but because of the caching this method performs it just means that the full 30mb remains in memory.

  • Why does ANTLR not parse the entire input?

    - by Martin Wiboe
    Hello, I am quite new to ANTLR, so this is likely a simple question. I have defined a simple grammar which is supposed to include arithmetic expressions with numbers and identifiers (strings that start with a letter and continue with one or more letters or numbers.) The grammar looks as follows: grammar while; @lexer::header { package ConFreeG; } @header { package ConFreeG; import ConFreeG.IR.*; } @parser::members { } arith: term | '(' arith ( '-' | '+' | '*' ) arith ')' ; term returns [AExpr a]: NUM { int n = Integer.parseInt($NUM.text); a = new Num(n); } | IDENT { a = new Var($IDENT.text); } ; fragment LOWER : ('a'..'z'); fragment UPPER : ('A'..'Z'); fragment NONNULL : ('1'..'9'); fragment NUMBER : ('0' | NONNULL); IDENT : ( LOWER | UPPER ) ( LOWER | UPPER | NUMBER )*; NUM : '0' | NONNULL NUMBER*; fragment NEWLINE:'\r'? '\n'; WHITESPACE : ( ' ' | '\t' | NEWLINE )+ { $channel=HIDDEN; }; I am using ANTLR v3 with the ANTLR IDE Eclipse plugin. When I parse the expression (8 + a45) using the interpreter, only part of the parse tree is generated: http://imgur.com/iBaEC.png Why does the second term (a45) not get parsed? The same happens if both terms are numbers. Thank you, Martin Wiboe

  • Debugging PHP Mail() and/or PHPMailer

    - by Agos
    Hi, I'm quite stuck with a problem sending mail from a PHP script. Some data: Shared hosting, no SSH access, only hosting provider panel PHP version 5.2.5 Last year I built a site which had no problems sending mail with the same hosting Let's say the domain is “domain.com” and my private address is “[email protected]” for anonimity's sake in the following code. Here's the code: <?php error_reporting(E_ALL); ini_set("display_errors", 1); $to = "[email protected]"; $subject = "Hi"; $body = "Test 1\nTest 2\nTest 3"; $headers = 'From: [email protected]' . "\r\n" . 'errors-to: [email protected]' . "\r\n" . 'X-Mailer: PHP/' . phpversion(); if (mail($to, $subject, $body, $headers)) { echo("Message successfully sent"); } else { echo("Message sending failed"); } require('class.phpmailer.php'); $message = "Hello world"; $mail = new PHPMailer(); $mail->CharSet = "UTF-8"; $mail->AddAddress("[email protected]", "Agos"); $mail->SetFrom("[email protected]","My Site"); $mail->Subject = "Test Message"; $mail->Body = $message; $mail->Send(); ?> And here is what I get: Message sending failed 'ai' = 'application/postscript', 'eps' = 'application/postscript', 'ps' = 'application/postscript', 'smi' = 'application/smil', 'smil' = 'application/smil', 'mif' = 'application/vnd.mif', 'xls' = 'application/vnd.ms-excel', 'ppt' = 'application/vnd.ms-powerpoint', 'wbxml' = 'application/vnd.wap.wbxml', 'wmlc' = 'application/vnd.wap.wmlc', 'dcr' = 'application/x-director', 'dir' = 'application/x-director', 'dxr' = 'application/x-director', 'dvi' = 'application/x-dvi', 'gtar' = 'application/x-gtar', 'php' = 'application/x-httpd-php', 'php4' = 'application/x-httpd-php', 'php3' = 'application/x-httpd-php', 'phtml' = 'application/x-httpd-php', 'phps' = 'application/x-httpd-php-source', 'js' = 'application/x-javascript', 'swf' = 'application/x-shockwave-flash', 'sit' = 'application/x-stuffit', 'tar' = 'application/x-tar', 'tgz' = 'application/x-tar', 'xhtml' = 'application/xhtml+xml', 'xht' = 'application/xhtml+xml', 'zip' = 'application/zip', 'mid' = 'audio/midi', 'midi' = 'audio/midi', 'mpga' = 'audio/mpeg', 'mp2' = 'audio/mpeg', 'mp3' = 'audio/mpeg', 'aif' = 'audio/x-aiff', 'aiff' = 'audio/x-aiff', 'aifc' = 'audio/x-aiff', 'ram' = 'audio/x-pn-realaudio', 'rm' = 'audio/x-pn-realaudio', 'rpm' = 'audio/x-pn-realaudio-plugin', 'ra' = 'audio/x-realaudio', 'rv' = 'video/vnd.rn-realvideo', 'wav' = 'audio/x-wav', 'bmp' = 'image/bmp', 'gif' = 'image/gif', 'jpeg' = 'image/jpeg', 'jpg' = 'image/jpeg', 'jpe' = 'image/jpeg', 'png' = 'image/png', 'tiff' = 'image/tiff', 'tif' = 'image/tiff', 'css' = 'text/css', 'html' = 'text/html', 'htm' = 'text/html', 'shtml' = 'text/html', 'txt' = 'text/plain', 'text' = 'text/plain', 'log' = 'text/plain', 'rtx' = 'text/richtext', 'rtf' = 'text/rtf', 'xml' = 'text/xml', 'xsl' = 'text/xml', 'mpeg' = 'video/mpeg', 'mpg' = 'video/mpeg', 'mpe' = 'video/mpeg', 'qt' = 'video/quicktime', 'mov' = 'video/quicktime', 'avi' = 'video/x-msvideo', 'movie' = 'video/x-sgi-movie', 'doc' = 'application/msword', 'word' = 'application/msword', 'xl' = 'application/excel', 'eml' = 'message/rfc822' ); return (!isset($mimes[strtolower($ext)])) ?

  • Application crashing on getting updated information from database using timer and storing it on loca

    - by Amit Battan
    In our multi - user application we are continuously interacting with database. We have a common class through which we are sending POST queries to database and obtaining xml files in return. We are using delegates of NSXMLParser to parse the obtained file. The problem with us is we are facing many crashes in it generally when application is idle and changed data in database is being fetched in background through timer which is invoked after every few seconds. We have also dealt with error handling through try and catch but it proves to be of no use in this case and mostly application crashes with following error : Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x0000000000000020 Strange thing is that many times the fetching of updated data at background works very fine, same methods being successfully executed under similar conditions but suddenly it crashes on one of them. The codes we are using is as follows: // we are using timer in this way: chkOnlineUser=[NSTimer scheduledTimerWithTimeInterval:15 target:mmObject selector:@selector(threadOnlineUser) userInfo:NULL repeats:YES];

  • iPhone Dev:Blurring of CALayers when rotated

    - by user153231
    Hello All, I have a CALayer with a png image as its content.When rotation is applied the layer looks blurry. I've searched for a cause for this problem and found out that the problem might be the half pixel problem, which makes the layer blurry if its frame.origin lays on fractions like 96.5, and they suggest to make the origin a whole number. Now, my layer's origin contains fractions because of the rotation i make as in: tempLayer.anchorPoint = CGPointMake(0.5,0.5); tempLayer.position = CGPointMake(200,100); tempLayer.bounds = CGRectMake(0,0,70,88); tempLayer.transform = CATransform3DMakeRotation(10.f*M_PI/180.f, 0.f, 0.f, 1.f); tempLayer.contents = (id)myImage; Basically i have three questions: 1) Is there a better way to rotate the layer? 2) The frame values are derived from the anchorPoint, position, bounds and transform values, how can i round my frame values to integer values and keep my rotation intact? 3) Can the CGRectIntegral function help me? If yes how? Thank you all in advance.
