  • Display a Photo Gallery using Asp.Net and SQL

    - by sweetcoder
    I have recently added photos to my SQL database and have displayed them on an *.aspx page using Asp:Image. The ImageUrl for this control stored in a separate *.aspx page. It works great for profile pictures. I have a new issue at hand. I need each user to be able to have their own photo gallery page. I want the photos to be stored in the sql database. Storing the photos is not difficult. The issue is displaying the photos. I want the photos to be stored in a thumbnail grid fashion, when the user clicks on the photo, it should bring up the photo on a separate page. What is the best way to do this. Obviously it is not to use Asp:Image. I am curious if I should use a Gridview. If so, how do I do that and should their be a thumbnail size stored in the database for this? Once the picture is click on how does the other page look so that it displays the correct image. I would think it is not correct to send the photoId through the url. Below is code from the page I use to display profile pictures. protected void Page_Load(object sender, EventArgs e) { string sql = "SELECT [ProfileImage] FROM [UserProfile] WHERE [UserId] = '" + User.Identity.Name.ToString() + "'"; string strCon = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["SocialSiteConnectionString"].ConnectionString; SqlConnection conn = new SqlConnection(strCon); SqlCommand comm = new SqlCommand(sql, conn); conn.Open(); Response.ContentType = "image/jpeg"; Response.BinaryWrite((byte[])comm.ExecuteScalar()); conn.Close(); }

  • Efficient Multiple Linear Regression in C# / .Net

    - by mrnye
    Does anyone know of an efficient way to do multiple linear regression in C#, where the number of simultaneous equations may be in the 1000's (with 3 or 4 different inputs). After reading this article on multiple linear regression I tried implementing it with a matrix equation: Matrix y = new Matrix( new double[,]{{745}, {895}, {442}, {440}, {1598}}); Matrix x = new Matrix( new double[,]{{1, 36, 66}, {1, 37, 68}, {1, 47, 64}, {1, 32, 53}, {1, 1, 101}}); Matrix b = (x.Transpose() * x).Inverse() * x.Transpose() * y; for (int i = 0; i < b.Rows; i++) { Trace.WriteLine("INFO: " + b[i, 0].ToDouble()); } However it does not scale well to the scale of 1000's of equations due to the matrix inversion operation. I can call the R language and use that, however I was hoping there would be a pure .Net solution which will scale to these large sets. Any suggestions? EDIT #1: I have settled using R for the time being. By using statconn (downloaded here) I have found it to be both fast & relatively easy to use this method. I.e. here is a small code snippet, it really isn't much code at all to use the R statconn library (note: this is not all the code!). _StatConn.EvaluateNoReturn(string.Format("output <- lm({0})", equation)); object intercept = _StatConn.Evaluate("coefficients(output)['(Intercept)']"); parameters[0] = (double)intercept; for (int i = 0; i < xColCount; i++) { object parameter = _StatConn.Evaluate(string.Format("coefficients(output)['x{0}']", i)); parameters[i + 1] = (double)parameter; }

  • Dynamics CRM Customer Portal Accelerator Installation

    - by saturdayplace
    (I've posted this question on the codeplex forums too, but have yet to get a response) I've got an on-premise installation of CRM and I'm trying to hook the portal to it. My connection string in web.config: <connectionStrings> <add name="Xrm" connectionString="Authentication Type=AD; Server=http://myserver:myport/MyOrgName; User ID=mydomain\crmwebuser; Password=thepassword" /> </connectionStrings> And my membership provider: <membership defaultProvider="CustomCRMProvider"> <providers> <add connectionStringName="Xrm" applicationName="/" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" minRequiredPasswordLength="1" minRequiredNonalphanumericCharacters="0" name="CustomCRMProvider" type="System.Web.Security.SqlMembershipProvider" /> </providers> </membership> Now, I'm super new to MS style web development, so please help me if I'm missing something. In Visual Studio 2010, when I go to Project ASP.NET Configuration it launches the Web Site Administration Tool. When I click the Security Tab there, I get the following error: There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: An error occurred while attempting to initialize a System.Data.SqlClient.SqlConnection object. The value that was provided for the connection string may be wrong, or it may contain an invalid syntax. Parameter name: connectionString I can't see what I'm doing wrong here. Does the user mydomain\crmwebuser need certain permissions in the SQL database, or somewhere else? edit: On the home page of the Web Site Administration Tool, I have the following: **Application**:/ **Current User Name**:MACHINENAME\USERACCOUNT Which is obviously a different set of credentials than mydomain\crmwebuser. Is this part of the problem?

  • Convert CRC-CCITT Kermit 16 DELPHI code to C#

    - by Mehdi Anis
    I am working on a function that will give me a Kermit CRC value from a HEX string. I have a piece of code in DELPHI. I am a .NET developer and need the code in C#. function CRC_16(cadena : string):word; var valuehex : word; i: integer; CRC : word; Begin CRC := 0; for i := 1 to length(cadena) do begin valuehex := ((ord(cadena[i]) XOR CRC) AND $0F) * $1081; CRC := CRC SHR 4; CRC := CRC XOR valuehex; valuehex := (((ord(cadena[i]) SHR 4) XOR LO(CRC)) AND $0F); CRC := CRC SHR 4; CRC := CRC XOR (valuehex * $1081); end; CRC_16 := (LO(CRC) SHL 8) OR HI(CRC); end; I got the code from this webpage: Kermit CRC in DELPHI I guess that Delphi function is correct. If any one can please convert the code to C# that will be great. I tried to convert to C#, but got lost in WORD data type and the LO function of Delphi. Thank you all.

  • How to encrypt Amazon CloudFront signature for private content access using canned policy

    - by Chet
    Has anyone using .net actually worked out how to successfully sign a signature to use with CloudFront private content? After a couple of days of attempts all I can get is Access Denied. I have been working with variations of the following code and also tried using OpenSSL.Net and AWSSDK but that does not have a sign method for RSA-SHA1 yet. The signature (data) looks like this {"Statement":[{"Resource":"http://xxxx.cloudfront.net/xxxx.jpg","Condition":?{"DateLessThan":?{"AWS:EpochTime":1266922799}}}]} This method attempts to sign the signature for use in the canned url. So of the variations have included chanding the padding used in the has and also reversing the byte[] before signing as apprently OpenSSL do it this way. public string Sign(string data) { using (SHA1Managed SHA1 = new SHA1Managed()) { RSACryptoServiceProvider provider = new RSACryptoServiceProvider(); RSACryptoServiceProvider.UseMachineKeyStore = false; // Amazon PEM converted to XML using OpenSslKey provider.FromXmlString("<RSAKeyValue><Modulus>....."); byte[] plainbytes = System.Text.Encoding.UTF8.GetBytes(data); byte[] hash = SHA1.ComputeHash(plainbytes); //Array.Reverse(sig); // I have see some examples that reverse the hash byte[] sig = provider.SignHash(hash, "SHA1"); return Convert.ToBase64String(sig); } } Its useful to note that I have verified the content is setup correctly in S3 and CloudFront by generating a CloudFront canned policy url using my CloudBerry Explorer. How do they do it? Any ideas would be much appreciated. Thanks

  • Code Trivia: optimize the code for multiple nested loops

    - by CodeToGlory
    I came across this code today and wondering what are some of the ways we can optimize it. Obviously the model is hard to change as it is legacy, but interested in getting opinions. Changed some names around and blurred out some core logic to protect. private static Payment FindPayment(Order order, Customer customer, int paymentId) { Payment payment = Order.Payments.FindById(paymentId); if (payment != null) { if (payment.RefundPayment == null) { return payment; } if (String.Compare(payment.RefundPayment, "refund", true) != 0 ) { return payment; } } Payment finalPayment = null; foreach (Payment testpayment in Order.payments) { if (testPayment.Customer.Name != customer.Name){continue;} if (testPayment.Cancelled) { continue; } if (testPayment.RefundPayment != null) { if (String.Compare(testPayment.RefundPayment, "refund", true) == 0 ) { continue; } } if (finalPayment == null) { finalPayment = testPayment; } else { if (testPayment.Value > finalPayment.Value) { finalPayment = testPayment; } } } if (finalPayment == null) { return payment; } return finalPayment; } Making this a wiki so code enthusiasts can answer without worrying about points.

  • Mapping interface or abstract class component

    - by Yann Trevin
    Please consider the following simple use case: public class Foo { public virtual int Id { get; protected set; } public virtual IBar Bar { get; set; } } public interface IBar { string Text { get; set; } } public class Bar : IBar { public virtual string Text { get; set; } } And the fluent-nhibernate map class: public class FooMap : ClassMap<Foo> { public FooMap() { Id(x => x.Id); Component(x => x.Bar, m => { m.Map(x => x.Text); }); } } While running any query with configuration, I get the following exception: NHibernate.InstantiationException: "Cannot instantiate abstract class or interface: NHMappingTest.IBar" It seems that NHibernate tries to instantiate an IBar object instead of the Bar concrete class. How to let Fluent-NHibernate know which concrete class to instantiate when the property returns an interface or an abstract base class? EDIT: Explicitly specify the type of component by writing Component<Bar> (as suggested by Sly) has no effect and causes the same exception to occur. EDIT2: Thanks to vedklyv and Paul Batum: such a mapping should be soon is now possible.

  • Why is WCF Stream response getting corrupted on write to disk?

    - by Alvin S
    I am wanting to write a WCF web service that can send files over the wire to the client. So I have one setup that sends a Stream response. Here is my code on the client: private void button1_Click(object sender, EventArgs e) { string filename = System.Environment.CurrentDirectory + "\\Picture.jpg"; if (File.Exists(filename)) File.Delete(filename); StreamServiceClient client = new StreamServiceClient(); int length = 256; byte[] buffer = new byte[length]; FileStream sink = new FileStream(filename, FileMode.CreateNew, FileAccess.Write); Stream source = client.GetData(); int bytesRead; while ((bytesRead = source.Read(buffer,0,length))> 0) { sink.Write(buffer,0,length); } source.Close(); sink.Close(); MessageBox.Show("All done"); } Everything processes fine with no errors or exceptions. The problem is that the .jpg file that is getting transferred is reported as being "corrupted or too large" when I open it. What am I doing wrong? On the server side, here is the method that is sending the file. public Stream GetData() { string filename = Environment.CurrentDirectory+"\\Chrysanthemum.jpg"; FileStream myfile = File.OpenRead(filename); return myfile; } I have the server configured with basicHttp binding with Transfermode.StreamedResponse.

  • Making a Text-To-Speech Wrapper in Android

    - by John Montgomery
    I am attempting to create a wrapper class for Google Android's Text-To-Speech functionality. However, I'm having trouble finding a way to have the system pause until after the onInit function has finished. Attached at the bottom is something of a solution I created based on what I found here: http://stackoverflow.com/questions/1160876/android-speech-how-can-you-read-text-in-android However, this solution does not seem to work. Any thoughts on why this might not be working, or what would be a good idea in order to make sure that any Speak() calls happen after my onInit() call? public class SpeechSynth implements OnInitListener { private TextToSpeech tts; static final int TTS_CHECK_CODE = 0; private int ready = 0; private ReentrantLock waitForInitLock = new ReentrantLock(); SpeechSynth( Activity screen ) { ready = 0; tts = new TextToSpeech( screen, this ); waitForInitLock.lock(); } public void onInit(int status) { if (status == TextToSpeech.SUCCESS) { ready = 1; } waitForInitLock.unlock(); } public int Speak( String text ) { if( ready == 1 ) { tts.speak(text, TextToSpeech.QUEUE_ADD, null); return 1; } else { return 0; } } } I have been able to make it so that I can pass a string of text through the constructor, then have it played in the onInit() function. However, I would really like to avoid having to destroy and re-create the whole text-to-speech engine every time I need to have my program say something different.

  • Using sqlite from vala without dependence on glib

    - by celil
    I need to use the Sqlite vapi without any depedence on GLib. SQlite is non-gobject library, so it should be possible to do that. However, when I try to compile the following file with the --profile posix option, using Sqlite; void main() { stdout.printf("Hello, World!"); } I get am error messages: sqlite3.vapi:357.56-357.59: error: The symbol `GLib' could not be found public int bind_blob (int index, void* value, int n, GLib.DestroyNotify destroy_notify); ^^^^ sqlite3.vapi:362.68-362.71: error: The symbol `GLib' could not be found public int bind_text (int index, owned string value, int n = -1, GLib.DestroyNotify destroy_notify = GLib.g_free); ^^^^ sqlite3.vapi:411.42-411.45: error: The symbol `GLib' could not be found public void result_blob (uint8[] data, GLib.DestroyNotify? destroy_notify = GLib.g_free); ^^^^ sqlite3.vapi:420.59-420.62: error: The symbol `GLib' could not be found public void result_text (string value, int length = -1, GLib.DestroyNotify? destroy_notify = GLib.g_free); ^^^^ Compilation failed: 4 error(s), 0 warning(s) It seems that several of the functions defined in the sqlite vapi make references to the GLib.g_free and GLib.DestroyNotify symbols. Are there any posix alternatives to those?

  • validate that URI is valid http URI

    - by Alfred
    Hi all, My problem: First of hopefully this is not a duplicate, but I could not find the right answer(right away). I would like to validate that an URI(http) is valid in Java. I came up with the following tests but I can't get them to pass. First I used getPort(), but then http://www.google.nl will return -1 on getPort(). This are the test I want to have passed Test: @Test public void testURI_Isvalid() throws Exception { assertFalse(HttpUtils.validateHTTP_URI("ttp://localhost:8080")); assertFalse(HttpUtils.validateHTTP_URI("ftp://localhost:8080")); assertFalse(HttpUtils.validateHTTP_URI("http://localhost:8a80")); assertTrue(HttpUtils.validateHTTP_URI("http://localhost:8080")); final String justWrong = "/schedule/get?uri=http://localhost:8080&time=1000000"; assertFalse(HttpUtils.validateHTTP_URI(justWrong)); assertTrue(HttpUtils.validateHTTP_URI("http://www.google.nl")); } This is what I came up with after I removed the getPort() part but this does not pass all my unit tests. Production code: public static boolean validateHTTP_URI(String uri) { final URI u; try { u = URI.create(uri); } catch (Exception e1) { return false; } return "http".equals(u.getScheme()); } This is the first test that is failing because I am no longer validating the getPort() part. Hopefully somebody can help me out. I think I am not using the right class to validate url's?? P.S: I don't want to connect to the server to validate the URI is correct. At least not yet in this step. I only want to validate scheme.

  • How to mock HTTPSession/FlexSession with TestNG and some Mocking Framework

    - by ifischer
    I'm developing a web application running on Tomcat 6, with Flex as Frontend. I'm testing my backend with TestNG. Currently, I'm trying to test the following method in my Java-Backend: public UserPE login(String mail, String password) { UserPE dbuser = findUserByMail(mail); if (dbuser == null || !dbuser.getPassword().equals(password)) throw new RuntimeException("Invalid username and/or password"); // Save logged in user FlexSession session = FlexContext.getFlexSession(); session.setAttribute("user", dbuser); return dbuser; } The method needs access to the FlexContext which only exists when i run it on the Servlet container (don't bother if you don't know Flex, it's more a Java-Mocking question in general). Otherwise i get a Nullpointer exception when calling session.setAttribute(). Unfortunately, I cannot set the FlexContext from outside, which would make me able to set it from my tests. It's just obtained inside the method. What would be the best way to test this method with a Mocking framework, without changing the method or the class which includes the method? And which framework would be the easiest for this use case (there are hardly other things i have to mock in my app, it's pretty simple)? Sorry I could try out all of them for myself and see how i could get this to work, but i hope that i'll get a quickstart with some good advices!

  • XML serialization query

    - by David Neale
    I have the following XML which needs deserializing/serializing: <instance> <dog> <items> <item> <label>Spaniel</label> </item> </items> </dog> <cat> <items> <item> <label>Tabby</label> </item> </items> </cat> </instance> I cannot change the XML structure. I need to map this to the following class: [Serializable, XmlRoot("instance")] public class AnimalInstance { public string Dog { get; set; } public string Cat { get; set; } } I'm not really sure where to start on this one without manually parsing the XML. I'd like to keep the code as brief as possible. Any ideas? (and no, my project doesn't actually involve cats and dogs).

    EDIT Came up with this to sanitize URI date params prior to passing off to Play router val ymdMatcher = "\\d{8}".r // matcher for yyyyMMdd URI param val ymdFormat = org.joda.time.format.DateTimeFormat.forPattern("yyyyMMdd") def ymd2Date(ymd: String) = ymdFormat.parseDateTime(ymd) override def onRouteRequest(r: RequestHeader): Option[Handler] = { import play.api.i18n.Messages ymdMatcher.findFirstIn(r.uri) map{ ymd=> try { ymd2Date( ymd); super.onRouteRequest(r) } catch { case e:Exception => // kick to "bad" action handler on invalid date Some(controllers.Application.bad(Messages("bad.date.format"))) } } getOrElse(super.onRouteRequest(r)) } ORIGINAL Let's say I want to return a BadRequest result type for all /foo URIs: override def onBadRequest(r: RequestHeader, error: String) = { BadRequest("Bad Request: " + error) } override def onRouteRequest(r: RequestHeader): Option[Handler] = { if(r.uri.startsWith("/foo") onBadRequest("go away") else super.onRouteRequest(r) } Of course does not work, since the expected return type is Option[play.api.mvc.Handler] What's the idiomatic way to deal with this, create a default Application controller method to handle filtered bad requests? Ideally, since I know in onRouteRequest that /foo is in fact a BadRequest, I'd like to call onBadRequest directly. Should note that this is a contrived example, am actually verifying a URI yyyyMMdd date param, and BadRequest-ing if it does not parse to a JodaTime instance -- basically a catch-all filter to sanitize a given date param rather than handling on every single controller method call, not to mention, avoiding cluttering up application log with useless stack traces re: invalid date parse conversions (have several MBs of these junk trace entries accruing daily due to users pointlessly manipulating the uri date in attempts to get at paid subscriber content)

  • establishing a socket connection from iPhone to MAC/PC

    - by user319572
    Hello, I just started getting into XCode and Co. What I am trying is to send accelerometer data via WLAN to a PC or MAC over a Socket connection. I am trying at the moment with the iPhone simulator, on the other site a netbook with a JAVA program shall receive a test string for starters. Unfortunately my socket will not initialize. What am I doing wrong? NSString *recStr = @"192.168.0.5"; //String with receiver IP NSHost *hoster = [NSHost hostWithName:recStr]; //create a host NSOutputStream *sendData; //create an output stream [NSStream getStreamsToHost:hoster port:8000 inputStream:nil outputStream:&sendData]; [sendData retain]; [sendData setDelegate:self]; [sendData open]; A warning says NSStream may not respond to '+getStreamsToHost:inputSream:outputStream:' So I guess parameters are wrong. But why and how to do it right? The program starts but I don't think I can send anything as long as this warning shows up (have not tried though). Thank you in advance, Andreas

  • Pseudocode: a clear definition?

    - by Cian E
    The following code is an example of what I think would qualify as pseudocode, since it does not execute in any language but the logic is correct. string checkRubric(gpa, major) bool brake = false num lastRange num rangeCounter string assignment = "unassigned" array bus['business']= array('person a'=>array(0, 2.9), 'person b'=>array(3, 4)) array cis['computer science']= array('person c'=>array(0, 2.9), 'person d'=>array(3, 4)) array lib['english']= array('person e'=>array(0, 4)) array rubric = array(bus, cis, lib) foreach (rubric as fieldAr) foreach (fieldAr as field => advisorAr) if (major == field) foreach (advisorAr as advisor => gpaRangeAr) rangeCounter = 0 foreach (gpaRangeAr as gpaValue) if (rangeCounter < 1) lastRange = gpaValue else if (gpa >= lastRange && gpa <= gpaValue) assignment = advisor brake = true break endif rangeCounter++ endforeach if (brake == true) break endif endforeach if (brake == true) break endif endif endforeach if (brake == true) break endif endforeach return assignment For the past couple of weeks I've been trying to create a clear definition of what pseudocode actually is. Is it relative to the programmer or is there an actual clearcut syntax? I say pseudocode is any code that does not execute, how about you? Thanks (links to this subject welcome)

  • Returning UTF-8 from a web service

    - by Marco Shaw
    Previous: Returning info from a Web Service I thought the previous answer made 100% sense, and I though I was out of the woods, but it still fails. An app I'm working with still seems to think what is being returned from the web service is ASCII encoded. Debugging it shows: <Envelope><Body><ReturnOneResponse><ReturnOneResult>&lt;xml version="1.0" encoding="UTF-8"&gt;&lt;Entry&gt;&lt;Symbol&gt;PACR&lt;/Symbol&gt;&lt;Company&gt;Pacer International, Inc.&lt;/Company&gt;&lt;MarketCap&gt;$229.0M&lt;/MarketCap&gt;&lt;PE&gt;18.7&lt;/PE&gt;&lt;Price&gt;6.56&lt;/Price&gt;&lt;Change&gt;0.42&lt;/Change&gt;&lt;PctChange&gt;6.84%&lt;/PctChange&gt;&lt;YTDChange&gt;107.59%&lt;/YTDChange&gt;&lt;/Entry&gt;</ReturnOneResult></ReturnOneResponse></Body></Envelope> So everything being returned from the web service seems to be changed into ASCII, and seems to refuse to read as UTF-8. Since my previous code in the above link, I also changed my string invocation: string value = @""; Still, that didn't help. Any other ideas?

  • Automatic INotifyPropertyChanged Implementation through T4 code generation?

    - by chrischu
    I'm currently working on setting up a new project of mine and was wondering how I could achieve that my ViewModel classes do have INotifyPropertyChanged support while not having to handcode all the properties myself. I looked into AOP frameworks but I think they would just blow up my project with another dependency. So I thought about generating the property implementations with T4. The setup would be this: I have a ViewModel class that declares just its Properties background variables and then I use T4 to generate the Property Implementations from it. For example this would be my ViewModel: public partial class ViewModel { private string p_SomeProperty; } Then T4 would go over the source file and look for member declarations named "p_" and generate a file like this: public partial class ViewModel { public string SomeProperty { get { return p_SomeProperty; } set { p_SomeProperty= value; NotifyPropertyChanged("SomeProperty"); } } } This approach has some advantages but I'm not sure if it can really work. So I wanted to post my idea here on StackOverflow as a question to get some feedback on it and maybe some advice how it can be done better/easier/safer.

  • JQuery BlockUI - How to unblock UI after file download?

    - by Dan
    Using ASP.Net, JQuery and BlockUI, I'm trying to unblock the UI after a download file dialog is shown. I block the UI when export button is clicked: <script type="text/javascript"> $(document).ready(function(){ $('#<%= BtnExport.ClientID%>').click(function(){ $.blockUI(); }); }); </script> After this, I generate the file server side using: private void SendFileToUser(byte[] file, string contentType, string filename) { Response.Clear(); Response.ContentType = contentType; Response.AppendHeader("Content-Disposition", "attachment; filename="+filename); Response.OutputStream.Write(file,0,file.Length); Response.OutputStream.Flush(); Response.End(); } After this code has executed, I would like to unblock the UI. I have considered different options: Poll using Ajax calls to see if the file has been generated. Store the file in Session and redirect to same page and generate download then. But both options seem ackward, and I think there must be a clever JavaScript way to get a handle on or wait for a file dialog. Any suggestions?

  • Linux Device Driver - what's wrong with my device_read()?

    - by Rob
    My device /dev/my_inc is meant to take a positive integer N represented as an ascii string, and store it. Any read from /dev/my_inc will produce the ascii string representation of N + 1. The problem is that when I cat /dev/my_inc, I only get the first byte of myinc_value output to my shell, even though I have bytes_read == 2 at the end of my loop. /* Read from the device *********************/ static ssize_t device_read(struct file *filp, char *buffer, size_t length, loff_t *offset) { char c; int bytes_read = 0; int value = myinc_value + 1; printk(KERN_INFO "my_inc device_read() called with value %d and msg %s.\n", value, msg); /* No bytes read if pointer to 0 */ if (*msg_ptr == 0) return 0; /* Put the incremented value in msg */ snprintf(msg, MAX_LENGTH, "%d", value); /* Put bytes from msg into user space buffer */ while (length && *msg_ptr) { c = *(msg_ptr++); printk(KERN_INFO "%s device_read() read %c.", DEV_NAME, c); if(put_user(c, buffer++)) return -EFAULT; length--; bytes_read++; } printk("my_inc device_read() returning %d.\n", bytes_read); /* Return bytes copied */ return bytes_read; }

  • Find, Find Next?

    - by Tanner
    Hello everyone, I am trying to make a find, find next function for my program, which I did manage to do with this code: int findPos = 0; private void button1_Click(object sender, EventArgs e) { try { string s = textBox1.Text; richTextBox1.Focus(); findPos = richTextBox1.Find(s, findPos, RichTextBoxFinds.None); richTextBox1.Select(findPos, s.Length); findPos += textBox1.Text.Length; //i = richTextBox1.Find(s, i + s.Length, RichTextBoxFinds.None); } catch { MessageBox.Show("No Occurences Found"); findPos = 0; } } And it works great in form1 but if I use this code and try to call it from form2 It doesn't do anything: //Form1 public void FindNext() { try { this.Focus(); Form2 frm2 = new Form2(); string s = frm2.textBox1.Text; richTextBox1.Focus(); findPos = richTextBox1.Find(s, findPos, RichTextBoxFinds.None); richTextBox1.Select(findPos + 1, s.Length); findPos += textBox1.Text.Length; } catch { MessageBox.Show("No Occurences Found"); findPos = 0; } } //Form2 private void button1_Click(object sender, EventArgs e) { Form1 frm1 = new Form1(); frm1.FindNext(); } Does any one know why this is? Thanks,Tanner.

  • XMPP SASL authentication on Ejabberd with PHP

    - by bucabay
    I'm trying to authenticate with an XMPP server using SASL. /** * Send Authentication, SASL * @return Bool * @param $username String * @param $password String */ function authenticate($username, $password) { $this->username = $username; $this->password = $password; var_dump($username, $password, $this->domain); $auth = base64_encode($username.'@'.$this->domain."\u0000".$username."\u0000".$password); $xml = '<auth mechanism="PLAIN" xmlns="urn:ietf:params:xml:ns:xmpp-sasl">'.$auth.'</auth>'; if ($this->write($xml)) { if ($xml = $this->listen(1, true)) { if (preg_match("/<success/i", $xml)) { $this->authenticated = $this->_sendStream(); } } } $this->events->trigger('authenticate', $this->authenticated); return $this->authenticated; } The XMPP server however responds with: <failure xmlns='urn:ietf:params:xml:ns:xmpp-sasl'><bad-protocol/></failure> This is against an Ejabberd server. When I open the XMPP stream, it advertises: <stream:features><starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'/><mechanisms xmlns='urn:ietf:params:xml:ns:xmpp-sasl'><mechanism>DIGEST-MD5</mechanism><mechanism>PLAIN</mechanism></mechanisms><register xmlns='http://jabber.org/features/iq-register'/></stream:features> So it seams to me that SASL - PLAIN should work. I have a JavaScript version, that works perfectly on OpenFire server. (I can't test it on Ejabberd at the moment) sendAuthentication: function() { clearTimeout(XMPP.sendAuthentication_timer); var auth = Base64.encode(XMPP.username+'@'+XMPP.domain+'\u0000'+XMPP.username+'\u0000'+XMPP.password); mySocket.events.receive.observe(XMPP.receivedAuthSuccess, function() { mySocket.send('<auth mechanism="PLAIN" xmlns="urn:ietf:params:xml:ns:xmpp-sasl">' + auth + '</auth>'); }); } So I can't get why the PHP version is not working.

  • Python dictionary formating

    - by None
    I made a python function to convert dictionaries to formatted strings. My goal was to have a function take a dictionary for input and turn it into a string that looked good. For example, something like "{'text':'Hello', 'blah':{'hi':'hello','hello':'hi'}}" would be turned into this: text: Hello blah: hi: hello hello: hi This is the code I wrote: indent = 0 def format_dict(d): global indent res = "" for key in d: res += (" " * indent) + key + ":\n" if not type(d[key]) == type({}): res += (" " * (indent + 1)) + d[key] + "\n" else: indent += 1 res += format_dict(d[key]) indent -= 1 return res #test print format_dict({'key with text content':'some text', 'key with dict content': {'cheese': 'text', 'item':{'Blah': 'Hello'}}}) It works like a charm. It checks if the dictionary item is another dictionary, in which it process that, or something else, in which it would use that as the value. The problem is: I can't have a dictionary and a string together in a dictionary item. For example: if I wanted blah: hi hello: hello again there'd be no way to do it. Is there some way I could have something like a list item in a dictionary. Something like this "{'blah':{'hi', 'hello':'hello again'}}"? And if you provide a solution could you tell me how I would need to change my code (if it did require changes). Note: I am using python 2.5
