  • C# Begin/EndReceive - how do I read large data?

    - by ryeguy
    When reading data in chunks of say, 1024, how do I continue to read from a socket that receives a message bigger than 1024 bytes until there is no data left? Should I just use BeginReceive to read a packet's length prefix only, and then once that is retrieved, use Receive() (in the async thread) to read the rest of the packet? Or is there another way? edit: I thought Jon Skeet's link had the solution, but there is a bit of a speedbump with that code. The code I used is: public class StateObject { public Socket workSocket = null; public const int BUFFER_SIZE = 1024; public byte[] buffer = new byte[BUFFER_SIZE]; public StringBuilder sb = new StringBuilder(); } public static void Read_Callback(IAsyncResult ar) { StateObject so = (StateObject) ar.AsyncState; Socket s = so.workSocket; int read = s.EndReceive(ar); if (read > 0) { so.sb.Append(Encoding.ASCII.GetString(so.buffer, 0, read)); if (read == StateObject.BUFFER_SIZE) { s.BeginReceive(so.buffer, 0, StateObject.BUFFER_SIZE, 0, new AyncCallback(Async_Send_Receive.Read_Callback), so); return; } } if (so.sb.Length > 0) { //All of the data has been read, so displays it to the console string strContent; strContent = so.sb.ToString(); Console.WriteLine(String.Format("Read {0} byte from socket" + "data = {1} ", strContent.Length, strContent)); } s.Close(); } Now this corrected works fine most of the time, but it fails when the packet's size is a multiple of the buffer. The reason for this is if the buffer gets filled on a read it is assumed there is more data; but the same problem happens as before. A 2 byte buffer, for exmaple, gets filled twice on a 4 byte packet, and assumes there is more data. It then blocks because there is nothing left to read. The problem is that the receive function doesn't know when the end of the packet is. This got me thinking to two possible solutions: I could either have an end-of-packet delimiter or I could read the packet header to find the length and then receive exactly that amount (as I originally suggested). There's problems with each of these, though. I don't like the idea of using a delimiter, as a user could somehow work that into a packet in an input string from the app and screw it up. It also just seems kinda sloppy to me. The length header sounds ok, but I'm planning on using protocol buffers - I don't know the format of the data. Is there a length header? How many bytes is it? Would this be something I implement myself? Etc.. What should I do?

  • Deploying ASP.Net web app with CruiseControl.Net and SVN -- getting rid of .svn folders

    - by Mercury821
    I have a CruiseControl.Net project set up to build an ASP.Net project, using an <svn task to pull the latest code from source control. On a successful build, I use a <buildpublisher to copy the site to a deployment folder. My problem is that the buildpublisher is copying everything to the destination folder, including every .svn folder and its contents. What is the easiest way to strip out the .svn folders before copying to the deployment folder?

  • Pattern Recognition for image comparision in .net

    - by vinod R
    hi Can anybody share code or algorithm(using pattern recognition) for image comparision in .net . I need to compare 2 images of different resolution and textures and the find the difference . Now i have code to find the difference between 2 images using C# // Load the images. Bitmap bm1 = (Bitmap) (Image.FromFile(txtFile1.Text)); Bitmap bm2 = (Bitmap) (Image.FromFile(txtFile2.Text)); // Make a difference image. int wid = Math.Min(bm1.Width, bm2.Width); int hgt = Math.Min(bm1.Height, bm2.Height); Bitmap bm3 = new Bitmap(wid, hgt); // Create the difference image. bool are_identical = true; int r1; int g1; int b1; int r2; int g2; int b2; int r3; int g3; int b3; Color eq_color = Color.Transparent; Color ne_color = Color.Transparent; for (int x = 0; x <= wid - 1; x++) { for (int y = 0; y <= hgt - 1; y++) { if (bm1.GetPixel(x, y).Equals(bm2.GetPixel(x, y))) { bm3.SetPixel(x, y, eq_color); } else { bm1.SetPixel(x, y, ne_color); are_identical = false; } } } // Display the result. picResult.Image = bm1; Bitmap Logo = new Bitmap(picResult.Image); Logo.MakeTransparent(Logo.GetPixel(1, 1)); picResult.Image = (Image)Logo; //this.Cursor = Cursors.Default; if ((bm1.Width != bm2.Width) || (bm1.Height != bm2.Height)) { are_identical = false; } if (are_identical) { MessageBox.Show("The images are identical"); } else { MessageBox.Show("The images are different"); } //bm1.Dispose() // bm2.Dispose() BUT this compare if the 2 images are of same resolution and size.if some shadow is there on one image(but the 2 images are same) it shows the difference between the image..so i am trying to compare using pattern recognition. Thanks in advance

  • Outlook Marking Email as Junk Email

    - by robertabead
    I know. I sound like a spammer but these emails are completely legitimate email confirmations for people that have signed up for an account on this website we developed. These emails all make it through to various mail providers (gmail, yahoo, aol, hotmail/live) but they always get directed into the Outlook Junk Email folder. I am have tried using Zend Framework mail, PEAR Mail and phpMailer. All of those methods result in the same thing happening. This seemed to start happening after Microsoft released their update to the Outlook Junk Email filter in January of this year. Following is the code in question: include_once('Mail.php'); include_once('Mail/mime.php'); $hdrs = array( 'From' => "Membership <[email protected]>", 'Subject' => 'Test Email', 'Reply-To'=> "[email protected]", 'Message-ID'=> "<" . str_pad(rand(0,12345678),8,'0',STR_PAD_LEFT) . "@mail.example.com>", 'Date'=> date("D, j M Y H:i:s O",time()), 'To'=> '[email protected]' ); $params = array('host'=>'mail.example.com','auth'=>false,'localhost' => 'www.example.com','debug'=>false); $crlf = "\n"; $mime = new Mail_mime($crlf); $mime->setTXTBody("TEST"); $mime->setHTMLBody("<html>\n<body>\nTest\n</body>\n</html>"); $body = $mime->get(); $hdrs = $mime->headers($hdrs); $mail =& Mail::factory('smtp',$params); $t=$mail->send('[email protected]', $hdrs, $body); As you can see we are using the PEAR Mail functionality in this test. This is the most basic test we could run and the above generated email gets dumped into the Outlook Junk Email folder. We have reverse DNS on the mail server and it matches the forward DNS, SPF and DKIM are set up and there is nothing "spammy" with the above content. Can anybody see something with the above code that could cause Outlook to mark it as Junk? Thanks!

  • Wanted: a very simple java RegExp API

    - by itsadok
    I'm tired of writing Pattern p = Pattern.compile(... Matcher m = p.matcher(str); if (m.find()) { ... Over and over again in my code. I was going to write a helper class to make it neater, but I then I wondered: is there a library that tries to provide a simpler facade for Regular Expressions in Java? I'm thinking something in the style of commons-lang and Guava.

  • How can I add HTML near the </body> tag within a Joomla Module?

    - by Luke
    I am quite new to using Joomla. I have created a custom module, however I would like to add some code near the tag (or near the opening tag) so it is guaranteed to be not nested in any tables whatsoever that might be in the template. I have located details on how to do this within a content plug-in, however I would like to just have the module. Any ideas? Thank you.

  • Open Source Alternative to ASP.NET membership

    - by Tony Lenzi
    I'm currently supporting a Python web app with increasingly complicated user/role/permission management requirements. Currently, we are rolling our own user, groups, permissions, etc. code and supporting database. I'd like to find something like ASP.NET membership that can help manage user authentication and authorization, rather than risk security issues in continuing to create an increasingly complicated custom solution. Are there any similar projects out there worth taking a look at?

  • Is there a way to get SSL certificate details using JavaScript?

    - by sHz
    Hi all, I'd like to gather certain details of an SSL certificate on a particular web-site. I know this is straightforward using the openssl tool on Linux/MacOSX. However is the same or similar possible in JavaScript? I understand that the browser handles socket connections and that the SSL handshake occurs prior to any party sending data. However in an XMLHTTPRequest, I'd like to know if its possible to get these details as some sort of response code etc?

  • 404 Pages in ASP.NET MVC

    - by Maxim Z.
    I'm building my first ASP.NET MVC website, and I'm trying to figure out how to implement a 404 page. Should I create a controller called "404Controller?" If so, how do I then register this Controller with IIS so that it redirects 404s to that page? Also, in a situation where something is not found (in the database, for example) by some other Controller code, how would I redirect the request to my 404 page?

  • Visual studio 2010 ajax control toolkit tab container

    - by Andreas
    Hi. We just upgraded to visual studio 2010 RC1 and all of a sudden our controls inside tabcontainer disappeared from the designer file. Actually, it all seemed good in the beginning, the project compiled nicely, but as soon as we did any change in the markup of a page and build the code for the controls inside the tabcontainer disappeared and we got errormessages like so "Error 3 The name 'ddlPeriodicityStartInMonth' does not exist in the current context " Does anyone know if any changes are made to tabcontainer to visual studio 2010 or if this just is a bug? Thanks in advance.

  • Reset element color to default stylesheet color (Jquery, Javascript)

    - by leaf dev
    I need to be able to reset an input field back to its original color after it has been possibly changed via javascript to a different value. The problem is I do not want to hard code the value obviously in case the stylesheet changes. I would like to use the default color used on the page. Is resetting the color like this fine, or is there a better way to do this? $('#theinput').css('color', '');

  • Cost of exception handlers in Python

    - by Thilo
    In another question, the accepted answer suggested replacing a (very cheap) if statement in Python code with a try/except block to improve performance. Coding style issues aside, and assuming that the exception is never triggered, how much difference does it make (performance-wise) to have an exception handler, versus not having one, versus having a compare-to-zero if-statement?

  • List - Strings - Textfiles

    - by b3y4z1d
    I've got a few questions concerning text files,list and strings. I wonder if it is possible to put in a code which reads the text in a textfile,and then using "string line;" or something else to define each new row of the text and turn all of them into one list. So I can sort the rows, remove a row or two or even all of them or search through the text for a specific row.

  • Pop3 to SMTP message custom forwarder in C#

    - by Troy
    I'd like to write a service that periodically checks a POP3 account for new messages and based on custom business logic forwards the messages to an appropriate "To", and possibly changes the "From" as well. I might need to keep some messages on the server until certain conditions are ready for them to be forwarded. I found a sample using Chilkat .NET components that might work: http://www.example-code.com/csharp/pop3_forwarder.asp My question is: Are there any other examples of this in the .NET space using any other components? Thanks!
