  • JQuery Toggle Button Trigger

    - by Ozzy
    Hi all, i have this code: $('.access a').toggle(function() { $('link').attr('href', 'styles/accessstyles.css'); $('body').css('font-size', '16px'); }, function() { $('link').attr('href', 'styles/styles.css'); $('body').css('font-size', text_sizes[text_current_size] + 'px'); }); It works fine. But how would i programmatically trigger the toggle instead of clicking on it?

  • How to bind a WPF CustomControl to a ListBox

    - by VivyG
    I've just started to learn WPF this week so please accept my apologies if I am being stupid or missing fundamental points! Iam trying to build a very simple Contact browser. I have a Collection of Contact objects that displayed in a ListBox control which shows the FullName of the Contact and to the right I have a customControl called BasicContactCard. This is the XAML for the ContacWindow that displays the ListBox: <DockPanel Width="auto" Height="auto" Margin="8 8 8 8"> <Border Height="56" HorizontalAlignment="Stretch" VerticalAlignment="Top" BorderThickness="1" CornerRadius="8" DockPanel.Dock="Top" Background="Beige"> <TextBox Height="32" Margin="23,5,135,5" Text="Search for contact here" FontStyle="Italic" Foreground="#FFAD9595" FontSize="14" BorderBrush="LightGray"/> </Border> <ListBox x:Name="contactList" DockPanel.Dock="Left" Width="192" Height="auto" Margin="5 4 0 8" /> <Grid> <Grid.RowDefinitions> <RowDefinition Height="1*" /> <RowDefinition Height="0.125*" /> </Grid.RowDefinitions> <local:BasicContactCard Margin="8 8 8 8" /> <Button Grid.Row="1" x:Name="exit" Content="Exit" HorizontalAlignment="Right" Width="50" Height="25" Click="exit_Click" /> </Grid> </DockPanel> and this is the XAML for the CustomControl: <DockPanel Width="auto " Height="auto" Margin="8,8,8,8"> <Grid Width="auto" Height="auto" DockPanel.Dock="Top"> <Grid.RowDefinitions> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> <RowDefinition Height="1*" /> </Grid.RowDefinitions> <TextBlock x:Name="companyField" Grid.Row="0" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Company"/> <TextBlock x:Name="contactField" Grid.Row="1" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Contact"/> <TextBlock x:Name="phoneField" Grid.Row="2" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="Phone"/> <TextBlock x:Name="emailField" Grid.Row="3" Width="auto" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="8,8,8,8" Text="email"/> </Grid> </DockPanel> The problem I have is how do I bind the individual elements of the CustomControl to the object behind the SelectedItem in the ListBox?

  • PHP: POST Request to ASP.NET website results in 500 server error when html tags included

    - by RyanJD
    My situation: I need to send text to an ASP.NET web service using POST. The entire page there is a form: <form name="aspnetForm" method="post" action="Discussion.aspx?classroom=lG39il1cotOAGJwiNvmQlIPfwmjikD%2fAHLhjjGInAZQ%3d&amp;Page=Posts&amp;ID=794239&amp;Sort=&amp;SortOrder=" id="aspnetForm"> So, I figured if I sent a POST request to this form with the correct inputs it would work. And, to an extent, it has. The form inputs are as follows: <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDw..." /> <input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWYQLrt..." /> And a bunch of other inputs. The code I have used is as follows: // grab form info $inputs = extract_form_inputs($discussion['body']); $inputs['__EVENTTARGET'] = 'ctl00$cphMain$ctl01$btnSubmit'; $inputs['ctl00$cphMain$ctl01$tbNickname'] = "Your Instructor"; $inputs['ctl00$cphMain$ctl01$reMessage'] = $message; // submit form $r = request_send($discussion['url'], $inputs); extract_form_inputs does exactly that. $discussion['body'] is the content of the page. $discussion['url'] is the URL of the page. request_send has two arguments: ($url, $post_array). It performs rawurlencode on each element of the array and joins them up as keypairs, in the same way as http_build_query. The request is url encoded properly, sent to the correct page, and works fine until I insert html tags. I have checked - the 'greater than' and 'less than' symbols ('<' and '') are url-encoded properly. However, the server responds with a 500 error. It accepts any other text. Has anyone else come across this sort of problem? Is there some setting on an ASP.NET server that denies html? I can't see this being the case - there is a rich text editor on the website that I am sending requests to. This text editor performs the same request as I am, only I am doing it remotely. The rich text editor sends html to the form - I have checked that, too, using javascript. Note: I do not have the power to modify the ASP.NET server.

  • Popping UIView crashes app

    I'm basically pushing a UIView from a UITableViewController and all it contains is a UIWebView.

  • How to get jQuery draggable elements scroll with mb.imageNavigator

    - by bulltorious
    I am using jQuery mb.imageNavigator (1.8) from http://pupunzi.open-lab.com/mb-jquery-components/mb-imagenavigator/ to implements a Risk type game adjucation system. Using the imageNavigator plugin I am able to scroll around a large game map of the world. My issue is when I declare some elements as draggable and drag them onto the map image, their location does not stay relative to where in the picture I put them. They just stay fixed on the screen no matter where I scroll. Does anyone know how to make the the draggable elements scroll with the image? Matteo posts about "you can add an additional content layer that overlay image and moves with it" and posts an example, but I can't make it work. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> ` <head> <script type="text/jscript" src="lib/jquery/jquery-1.3.2.js"> </script> <script type="text/jscript" src="lib/jquery/jquery-ui-1.7.2.custom.min.js"> </script> <script type="text/jscript" src="lib/utilities/mbImgNav.min.js_0.js"> </script> <script type="text/jscript" src="lib/utilities/start.js"> </script> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>New Web Project</title> </head> <body> <div id="AdamsAshTray" style="float:right; background-color:red; z-index:999"> test test test </div> <div id="navArea"> <div imageUrl="someimage" navPosition="BR" navWidth="100" style="display:none;" class="imagesContainer"> <span class="title">zuccheriera</span> <div class="description"> <STRONG>description1</STRONG> </div> </div> </div> </body> $(document).ready(function(){ $("#navArea").imageNavigator({ areaWidth:1820, areaHeight:1000, draggerStyle: "1px dotted red", navOpacity: .8 }) $("#AdamsAshTray").draggable({ grid: [20,20] }); })`

  • Telnet connection using c#

    - by alejandrobog
    Our office currently uses telnet to query an external server. The procedure is something like this. Connect - telnet opent 128........ 25000 Query - we paste the query and then hit alt + 019 Response - We receive the response as text in the telnet window So I’m trying to make this queries automatic using a c# app. My code is the following First the connection. (No exceptions) SocketClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); String szIPSelected = txtIPAddress.Text; String szPort = txtPort.Text; int alPort = System.Convert.ToInt16(szPort, 10); System.Net.IPAddress remoteIPAddress = System.Net.IPAddress.Parse(szIPSelected); System.Net.IPEndPoint remoteEndPoint = new System.Net.IPEndPoint(remoteIPAddress, alPort); SocketClient.Connect(remoteEndPoint); Then I send the query (No exceptions) string data ="some query"; byte[] byData = System.Text.Encoding.ASCII.GetBytes(data); SocketClient.Send(byData); Then I try to receive the response byte[] buffer = new byte[10]; Receive(SocketClient, buffer, 0, buffer.Length, 10000); string str = Encoding.ASCII.GetString(buffer, 0, buffer.Length); txtDataRx.Text = str; public static void Receive(Socket socket, byte[] buffer, int offset, int size, int timeout) { int startTickCount = Environment.TickCount; int received = 0; // how many bytes is already received do { if (Environment.TickCount > startTickCount + timeout) throw new Exception("Timeout."); try { received += socket.Receive(buffer, offset + received, size - received, SocketFlags.None); } catch (SocketException ex) { if (ex.SocketErrorCode == SocketError.WouldBlock || ex.SocketErrorCode == SocketError.IOPending || ex.SocketErrorCode == SocketError.NoBufferSpaceAvailable) { // socket buffer is probably empty, wait and try again Thread.Sleep(30); } else throw ex; // any serious error occurr } } while (received < size); } Every time I try to receive the response I get "an exsiting connetion has forcibly closed by the remote host" if open telnet and send the same query I get a response right away Any ideas, or suggestions?

  • Problems with CGI wrapper for PHP

    - by user205878
    I'm having a bugger of a time with a CGI wrapper for PHP. I know very little about CGI and PHP as CGI. Here's what I know about the system: Solaris 10 on a 386 Suhosin PHP normally running as CGI, with cgiwrap (http://cgiwrap.sourceforge.net/). I am not able to find an example wrapper.cgi on the server to look at. Shared hosting (virtual host), so I don't have access to Apache config. But the admins are not helpful. Switching hosts is not an option. Options directive cannot be overridden in .htaccess (ExecCGI, for example). .htaccess: AddHandler php-handler .php Action php-handler "/bin/test.cgi" ~/public_html/bin/test.cgi: #!/usr/bin/sh # Without these 2 lines, I get an Internal Server Error echo "Content-type: text/html" echo "" exec "/path/to/php-cgi" 'foo.php'; /bin/foo.php: <?php echo "this is foo.php!"; Output of http://mysite.com/bin/test.cgi: X-Powered-By: PHP/5.2.11 Content-type: text/html echo "Content-type: text/html" echo "" exec "/path/to//php-cgi" 'foo.php'; Output of http:/ /mysite.com/anypage.php: X-Powered-By: PHP/5.2.11 Content-type: text/html echo "Content-type: text/html" echo "" exec "/path/to//php-cgi" 'foo.php'; The things I note are: PHP is being executed, as noted by the X-Powered-By ... header. The source of /bin/test.cgi is output in the results. No matter what I put as the second argument of exec, it isn't passed to the php binary. I've tried '-i' to get phpinfo, '-v' to get the version... When I execute test.cgi via the shell, I get the expected results (the argument is passed to php, and it is reflected in the output). Any ideas about how to get this to work? UPDATE It appears that the reason the source of the test.cgi was appearing was due to errors. Anytime fatal error occurred, either within the cgi itself or with the command being executed by exec, it would cause the source of the cgi to appear. Within test.cgi, I can get the proper output with exec "/path/to/php-cgi" -h (I get the same thing as I would from CLI).

  • Help needed with AES between Java and Objective-C (iPhone)....

    - by Simon Lee
    I am encrypting a string in objective-c and also encrypting the same string in Java using AES and am seeing some strange issues. The first part of the result matches up to a certain point but then it is different, hence when i go to decode the result from Java onto the iPhone it cant decrypt it. I am using a source string of "Now then and what is this nonsense all about. Do you know?" Using a key of "1234567890123456" The objective-c code to encrypt is the following: NOTE: it is a NSData category so assume that the method is called on an NSData object so 'self' contains the byte data to encrypt. - (NSData *)AESEncryptWithKey:(NSString *)key { char keyPtr[kCCKeySizeAES128+1]; // room for terminator (unused) bzero(keyPtr, sizeof(keyPtr)); // fill with zeroes (for padding) // fetch key data [key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF8StringEncoding]; NSUInteger dataLength = [self length]; //See the doc: For block ciphers, the output size will always be less than or //equal to the input size plus the size of one block. //That's why we need to add the size of one block here size_t bufferSize = dataLength + kCCBlockSizeAES128; void *buffer = malloc(bufferSize); size_t numBytesEncrypted = 0; CCCryptorStatus cryptStatus = CCCrypt(kCCEncrypt, kCCAlgorithmAES128, kCCOptionPKCS7Padding, keyPtr, kCCKeySizeAES128, NULL /* initialization vector (optional) */, [self bytes], dataLength, /* input */ buffer, bufferSize, /* output */ &numBytesEncrypted); if (cryptStatus == kCCSuccess) { //the returned NSData takes ownership of the buffer and will free it on deallocation return [NSData dataWithBytesNoCopy:buffer length:numBytesEncrypted]; } free(buffer); //free the buffer; return nil; } And the java encryption code is... public byte[] encryptData(byte[] data, String key) { byte[] encrypted = null; Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); byte[] keyBytes = key.getBytes(); SecretKeySpec keySpec = new SecretKeySpec(keyBytes, "AES"); try { Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC"); cipher.init(Cipher.ENCRYPT_MODE, keySpec); encrypted = new byte[cipher.getOutputSize(data.length)]; int ctLength = cipher.update(data, 0, data.length, encrypted, 0); ctLength += cipher.doFinal(encrypted, ctLength); } catch (Exception e) { logger.log(Level.SEVERE, e.getMessage()); } finally { return encrypted; } } The hex output of the objective-c code is - 7a68ea36 8288c73d f7c45d8d 22432577 9693920a 4fae38b2 2e4bdcef 9aeb8afe 69394f3e 1eb62fa7 74da2b5c 8d7b3c89 a295d306 f1f90349 6899ac34 63a6efa0 and the java output is - 7a68ea36 8288c73d f7c45d8d 22432577 e66b32f9 772b6679 d7c0cb69 037b8740 883f8211 748229f4 723984beb 50b5aea1 f17594c9 fad2d05e e0926805 572156d As you can see everything is fine up to - 7a68ea36 8288c73d f7c45d8d 22432577 I am guessing I have some of the settings different but can't work out what, I tried changing between ECB and CBC on the java side and it had no effect. Can anyone help!? please....

  • CSS formatter NOT based on CSS Tidy?

    - by Abdu
    I can't find a css formatter (web based or Windows app) which formats the css where it puts the open brace on its own line aligned with its close brace, plus indents the attributes. The web based css formatters out here seem to be based on CSSTidy which doesn't do what I want. I don't like this CSSTidy format: .example { font-size: 3em; } I want: .example { font-size: 3em; }

  • php if clause inside foreach not retrieving data correctly

    - by Mike
    Here's my issue: In my controller, I want to grab user input from a form. I then parse the input, and compare it to database values to ensure I'm grabbing the correct input. I simply want to match the user's answers to the question, grab the user ID, the question ID, and then determine if the answer applies to a multiple choice or checkbox question, or something else. I take those values and insert them into the answer table. Ignore the waiver stuff. I'll test that once I get the answers input correctly. // add answers and waiver consent records try { $answerArray = array(); $waiverArray = array(); // retrieve answers, waiver consents, and the question ID's from form object foreach ($formData as $key => $value) { $parts = explode("_", $key); if ($parts[0] == 'question') { array_push($answerArray, $value); } if ($parts[0] == 'waiverTitle') { array_push($waiverArray, $value); } } $questions = new Model_DbTable_Questions(); $questionResults = $questions->getQuestionResults($session->idEvent); foreach ( $questionResults as $qr ) { if ($qr ['questionType'] == 'multipleChoice' || $qr ['questionType'] == 'checkBox') { foreach ( $answerArray as $aa ) { $answerData = $answers->addAnswer ( $lastUserID, $qr ['idQuestion'], null, $aa ); echo count ( $answerData ) .

  • Z-Index and javascript for rollover

    - by Raffaele
    I have a container (div) with a background image. In this div there is a menu - a horizontal list. What I need is to insert an image onMouseOver, positioning it absolutely, and showing it behind the text (of course!) AND on top of the div's background image. I also use jQuery, but I think this doesn't matter. The problem can be viewed online. Go to http://www.w3schools.com/css/tryit.asp?filename=trycss_zindex and paste the following text <html> <head> <style type="text/css"> img { top: 0; left: 0; position:absolute; z-index:-1; } #main { color: red; margin: 30px; padding: 20px; width: 700px; min-height: 400px; z-index: -2; background-image: url("http://www.google.com/logos/mother10-hp.gif"); background-repeat: no-repeat; } </style> </head> <body> <div id="main"> <h1>Z-Index question:</h1> <img src="w3css.gif" width="100" height="140" /> <p>How can we place the green pic between the text and the div#main?</p> <p>I need the green gif to appear</p> <ol> <li>On top of #main's background image</li> <li>Behind the text</li> </ol> </div> </body> </html>

  • Drawing a texture with an alpha channel doesn't work -- draws black

    - by DevDevDev
    I am modifying GLPaint to use a different background, so in this case it is white. Anyway the existing stamp they are using assumes the background is black, so I made a new background with an alpha channel. When I draw on the canvas it is still black, what gives? When I actually draw, I just bind the texture and it works. Something is wrong in this initialization. Here is the photo - (id)initWithCoder:(NSCoder*)coder { CGImageRef brushImage; CGContextRef brushContext; GLubyte *brushData; size_t width, height; if (self = [super initWithCoder:coder]) { CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer; eaglLayer.opaque = YES; // In this application, we want to retain the EAGLDrawable contents after a call to presentRenderbuffer. eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGBA8, kEAGLDrawablePropertyColorFormat, nil]; context = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES1]; if (!context || ![EAGLContext setCurrentContext:context]) { [self release]; return nil; } // Create a texture from an image // First create a UIImage object from the data in a image file, and then extract the Core Graphics image brushImage = [UIImage imageNamed:@"test.png"].CGImage; // Get the width and height of the image width = CGImageGetWidth(brushImage); height = CGImageGetHeight(brushImage); // Texture dimensions must be a power of 2. If you write an application that allows users to supply an image, // you'll want to add code that checks the dimensions and takes appropriate action if they are not a power of 2. // Make sure the image exists if(brushImage) { brushData = (GLubyte *) calloc(width * height * 4, sizeof(GLubyte)); brushContext = CGBitmapContextCreate(brushData, width, width, 8, width * 4, CGImageGetColorSpace(brushImage), kCGImageAlphaPremultipliedLast); CGContextDrawImage(brushContext, CGRectMake(0.0, 0.0, (CGFloat)width, (CGFloat)height), brushImage); CGContextRelease(brushContext); glGenTextures(1, &brushTexture); glBindTexture(GL_TEXTURE_2D, brushTexture); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, brushData); free(brushData); } //Set up OpenGL states glMatrixMode(GL_PROJECTION); CGRect frame = self.bounds; glOrthof(0, frame.size.width, 0, frame.size.height, -1, 1); glViewport(0, 0, frame.size.width, frame.size.height); glMatrixMode(GL_MODELVIEW); glDisable(GL_DITHER); glEnable(GL_TEXTURE_2D); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_DST_ALPHA); glEnable(GL_POINT_SPRITE_OES); glTexEnvf(GL_POINT_SPRITE_OES, GL_COORD_REPLACE_OES, GL_TRUE); glPointSize(width / kBrushScale); } return self; }

  • Papervision 3D: How can I force dimensions on a collada file

    - by imadethisthing
    Hey everyone, I'm working with Collada files and I need them to be a certain size. When instantiating them in pv3d you set the filename, materials, and scale. Scale works like a percentage, and there's no way to get the width, height, or depth of the DAE once in flash. I want to be able to specify the size of DAE in 3D space relative to other pv3d native geometry.

  • Whats happening to my HTML?

    - by user156814
    I am making changes to my website, and I just noticed that things look different. In IE, the content doesnt center, theres a margin on my content, and the font looks bigger in chrome.. I ran it through Yahoo's HTML validator and the error I get is line 1 - Error: character "" not allowed in prolog. I believe that there may be some sort of whitespace being sent before the DOC TYPE, but I cant seem to fix it. The HTML looks fine in my text editor (Notepad++) so I dont know what the problem is. Im using a strict DOC Type. Everything was fine before I made any changes, but I cant pinpoint what caused the change. If it helps, I'm using a Framework (Kohana). My initial thought was that something was being sent to the browser by an echo or something, but I couldnt find any echo statements. I dont know what could be causing this... If you want to see any code or HTML just ask. Thanks. Heres the HTML (only head and doctype) via the page source in Google Chrome There seems to be some foreign characters in the source that I've never seen before, yet dont show up anywhere else (yahoo, or otherwise) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Recent Debates - Clashing Thoughts</title> <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> <meta http-equiv="Content-Language" content="en-us" /> <meta name="description" content="Clashing Thoughts is a great place to argue!

  • Good practices for a robust FTP script

    - by dutch
    What are the things a script should do to ensure that files have been FTPed correctly? Following are the things I have in mind: 1) use high level scripting language like python or perl instead of shell script for a more comprehensive functionality and error handling 2) check that the file exists at the destination after FTP 3) check destination file size. This is a little bit difficult because file size will change if the source and destination are running different OS. Any tips on how to go about this?

  • Ho to convert classname as string to a class ?

    - by Roland Bengtsson
    I have classnames in a stringlist. For example it could be 'TPlanEvent', 'TParcel', 'TCountry' etc. Now I want to find out the sizes by looping the list. It works to have: Size := TCountry.InstanceSize; But I want it like this: for i := 0 to ClassList.Count - 1 do Size := StringToClass(ClassList[i]).InstanceSize; Obviously my question is what to write instead of method StringToClass to convert the string to a class.

  • Implementing a robust async stream reader

    - by Jon
    I recently provided an answer to this question: C# - Realtime console output redirection. As often happens, explaining stuff (here "stuff" was how I tackled a similar problem) leads you to greater understanding and/or, as is the case here, "oops" moments. I realized that my solution, as implemented, has a bug. The bug has little practical importance, but it has an extremely large importance to me as a developer: I can't rest easy knowing that my code has the potential to blow up. Squashing the bug is the purpose of this question. I apologize for the long intro, so let's get dirty. I wanted to build a class that allows me to receive input from a Stream in an event-based manner. The stream, in my scenario, is guaranteed to be a FileStream and there is also an associated StreamReader already present to leverage. The public interface of the class is this: public class MyStreamManager { public event EventHandler<ConsoleOutputReadEventArgs> StandardOutputRead; public void StartSendingEvents(); public void StopSendingEvents(); } Obviously this specific scenario has to do with a console's standard output, but that is a detail and does not play an important role. StartSendingEvents and StopSendingEvents do what they advertise; for the purposes of this discussion, we can assume that events are always being sent without loss of generality. The class uses these two fields internally: protected readonly StringBuilder inputAccumulator = new StringBuilder(); protected readonly byte[] buffer = new byte[256]; The functionality of the class is implemented in the methods below. To get the ball rolling: public void StartSendingEvents(); { this.stopAutomation = false; this.BeginReadAsync(); } To read data out of the Stream without blocking, and also without requiring a carriage return char, BeginRead is called: protected void BeginReadAsync() { if (!this.stopAutomation) { this.StandardOutput.BaseStream.BeginRead( this.buffer, 0, this.buffer.Length, this.ReadHappened, null); } } The challenging part: BeginRead requires using a buffer. This means that when reading from the stream, it is possible that the bytes available to read ("incoming chunk") are larger than the buffer. Since we are only handing off data from the stream to a consumer, and that consumer may well have inside knowledge about the size and/or format of these chunks, I want to call event subscribers exactly once for each chunk. Otherwise the abstraction breaks down and the subscribers have to buffer the incoming data and reconstruct the chunks themselves using said knowledge. This is much less convenient to the calling code, and detracts from the usefulness of my class. To this end, if the buffer is full after EndRead, we don't send its contents to subscribers immediately but instead append them to a StringBuilder. The contents of the StringBuilder are only sent back whenever there is no more to read from the stream (thus preserving the chunks). private void ReadHappened(IAsyncResult asyncResult) { var bytesRead = this.StandardOutput.BaseStream.EndRead(asyncResult); if (bytesRead == 0) { this.OnAutomationStopped(); return; } var input = this.StandardOutput.CurrentEncoding.GetString( this.buffer, 0, bytesRead); this.inputAccumulator.Append(input); if (bytesRead < this.buffer.Length) { this.OnInputRead(); // only send back if we 're sure we got it all } this.BeginReadAsync(); // continue "looping" with BeginRead } After any read which is not enough to fill the buffer, all accumulated data is sent to the subscribers: private void OnInputRead() { var handler = this.StandardOutputRead; if (handler == null) { return; } handler(this, new ConsoleOutputReadEventArgs(this.inputAccumulator.ToString())); this.inputAccumulator.Clear(); } (I know that as long as there are no subscribers the data gets accumulated forever. This is a deliberate decision). The good This scheme works almost perfectly: Async functionality without spawning any threads Very convenient to the calling code (just subscribe to an event) Maintains the "chunkiness" of the data; this allows the calling code to use inside knowledge of the data without doing any extra work Is almost agnostic to the buffer size (it will work correctly with any size buffer irrespective of the data being read) The bad That last almost is a very big one. Consider what happens when there is an incoming chunk with length exactly equal to the size of the buffer. The chunk will be read and buffered, but the event will not be triggered. This will be followed up by a BeginRead that expects to find more data belonging to the current chunk in order to send it back all in one piece, but... there will be no more data in the stream. In fact, as long as data is put into the stream in chunks with length exactly equal to the buffer size, the data will be buffered and the event will never be triggered. This scenario may be highly unlikely to occur in practice, especially since we can pick any number for the buffer size, but the problem is there. Solution? Unfortunately, after checking the available methods on FileStream and StreamReader, I can't find anything which lets me peek into the stream while also allowing async methods to be used on it. One "solution" would be to have a thread wait on a ManualResetEvent after the "buffer filled" condition is detected. If the event is not signaled (by the async callback) in a small amount of time, then more data from the stream will not be forthcoming and the data accumulated so far should be sent to subscribers. However, this introduces the need for another thread, requires thread synchronization, and is plain inelegant. Specifying a timeout for BeginRead would also suffice (call back into my code every now and then so I can check if there's data to be sent back; most of the time there will not be anything to do, so I expect the performance hit to be negligible). But it looks like timeouts are not supported in FileStream. Since I imagine that async calls with timeouts are an option in bare Win32, another approach might be to PInvoke the hell out of the problem. But this is also undesirable as it will introduce complexity and simply be a pain to code. Is there an elegant way to get around the problem? Thanks for being patient enough to read all of this.

  • ListBox item doesn't get refresh in WPF?

    - by sanjeev40084
    I have a listbox which has couple of items. When double clicked on each item, the user get option to edit item (text of item). Now once i update the item, my item in listbox doesn't get updated. The first window (one which has listbox) is in MainWindow.xaml file and second window is in EditTaskView.xaml(one which let's edit the items text) file. The code that displays items in lists is: Main.Windows.cs public static ObservableCollection TaskList; public void GetTask() { TaskList = new ObservableCollection<Task> { new Task("Task1"), new Task("Task2"), new Task("Task3"), new Task("Task4") }; lstBxTask.ItemsSource = TaskList; } private void lstBxTask_MouseDoubleClick(object sender, MouseButtonEventArgs e) { var selectedTask = (Task)lstBxTask.SelectedItem; EditTask.txtBxEditedText.Text = selectedTask.Taskname; EditTask.PreviousTaskText = selectedTask.Taskname; EditTask.Visibility = Visibility.Visible; } The xaml code that displays the list: <ListBox x:Name="lstBxTask" Style="{StaticResource ListBoxItems}" MouseDoubleClick="lstBxTask_MouseDoubleClick"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <Rectangle Style="{StaticResource LineBetweenListBox}"/> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Taskname}" Style="{StaticResource TextInListBox}"/> <Button Name="btnDelete" Style="{StaticResource DeleteButton}" Click="btnDelete_Click"/> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <ToDoTask:EditTaskView x:Name="EditTask" Grid.Row="1" Grid.RowSpan="2" Grid.ColumnSpan="2" Visibility="Collapsed"/> The Save button in TaskEditView.xaml does this: public string PreviousTaskText { get; set; } private void btnSaveEditedText_Click(object sender, RoutedEventArgs e) { foreach (var t in MainWindow.TaskList) { if (t.Taskname == PreviousTaskText) { t.Taskname = txtBxEditedText.Text; } } Visibility = Visibility.Collapsed; } TaskList is the ObservableCollection, and i though once you update the value the UI gets refreshed. But doesn't seem to work that way. What am i missing?
