  • Unrequired property keeps getting data-val-required attribute

    - by frennky
    This is the model with it's validation: [MetadataType(typeof(TagValidation))] public partial class Tag { } public class TagValidation { [Editable(false)] [HiddenInput(DisplayValue = false)] public int TagId { get; set; } [Required] [StringLength(20)] [DataType(DataType.Text)] public string Name { get; set; } //... } Here is the view: <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>Tag</legend> <div>@Html.EditorForModel()</div> <p> <input type="submit" value="Create" /> </p> </fieldset> } <div> @Html.ActionLink("Back to List", "Index") </div> And here is what get's renderd: <form action="/Tag/Create" method="post"> <fieldset> <legend>Tag</legend> <div><input data-val="true" data-val-number="The field TagId must be a number." data-val-required="The TagId field is required." id="TagId" name="TagId" type="hidden" value="" /> <div class="editor-label"><label for="Name">Name</label></div> <div class="editor-field"><input class="text-box single-line" data-val="true" data-val-length="The field Name must be a string with a maximum length of 20." data-val-length-max="20" data-val-required="The Name field is required." id="Name" name="Name" type="text" value="" /> <span class="field-validation-valid" data-valmsg-for="Name" data-valmsg-replace="true"></span></div> ... </fieldset> </form> The problem is that TagId validation gets generated althoug thare is no Required attribute set on TagId property. Because of that I can't even pass the client-side validation in order to create new Tag in db. What am I missing?

  • XNA 4.0 - What happens when the window is minimized?

    - by Conrad Clark
    Hello. I'm learning F#, and decided to try making simple XNA games for windows using F# (pure enthusiasm) , and got a window with some images showing up. Here's the code: (*Methods*) member self.DrawSprites() = _spriteBatch.Begin() for i = 0 to _list.Length-1 do let spentity = _list.List.ElementAt(i) _spriteBatch.Draw(spentity.ImageTexture,new Rectangle(100,100,(int)spentity.Width,(int)spentity.Height),Color.White) _spriteBatch.End() (*Overriding*) override self.Initialize() = ChangeGraphicsProfile() _graphicsDevice <- _graphics.GraphicsDevice _list.AddSprite(0,"NagatoYuki",992.0,990.0) base.Initialize() override self.LoadContent() = _spriteBatch <- new SpriteBatch(_graphicsDevice) base.LoadContent() override self.Draw(gameTime : GameTime) = base.Draw(gameTime) _graphics.GraphicsDevice.Clear(Color.CornflowerBlue) self.DrawSprites() And the AddSprite Method: member self.AddSprite(ID : int,imageTexture : string , width : float, height : float) = let texture = content.Load<Texture2D>(imageTexture) list <- list @ [new SpriteEntity(ID,list.Length, texture,Vector2.Zero,width,height)] The _list object has a ContentManager, here's the constructor: type SpriteList(_content : ContentManager byref) = let mutable content = _content let mutable list = [] But I can't minimize the window, since when it regains its focus, i get this error: ObjectDisposedException Cannot access a disposed object. Object name: 'GraphicsDevice'. What is happening?

  • String.substring(index) has stoped my thread in debug mode.

    - by Arkaha
    Hello! I work with j2me polish 2.0.7, in eclipse 3.4.2, with wtk2.5.2_01. I create control which draws text: normal, bold, and italic. The code below is parsing raw text, and search for * and _ symbols, if found than add to draw vector the text and the drawer, and it's just stops after getting second time to the line 58: String test = new String(raw_text_buff.substring(iter)); it stops in raw_text_buff.substring(iter), ONLY in debug mode.. raw text is: bla bla bla *1000* bla bla Full code: private String raw_text = "bla bla bla *1000* bla bla"; Vector draw_items = null; private void prepareText() { char open_char = 0; int open_pos = 0; Object []param = null; StringBuffer sb = new StringBuffer(); String raw_text_buff = new String(raw_text); int iter = 0; boolean was_reset = false; while(true) { char c = raw_text_buff.charAt(iter); if(iter == raw_text_buff.length() || c == '*' || c == '_') { if(sb.length() > 0) { BmFont viewer = null; String str = sb.toString(); if(open_char == '*' && null != bm_strong) { viewer = bm_strong.getViewer(str); }else if(open_char == '_' && null != bm_italic) { viewer = bm_italic.getViewer(str); }else if(null != bm_normal) { viewer = bm_normal.getViewer(str); }else { } param = new Object[2]; param[0] = str; param[1] = viewer; if(null == draw_items) draw_items = new Vector(); draw_items.addElement(param); sb = new StringBuffer(); if(open_char == 0 && (c == '*' || c=='_')) open_char = c; else open_char = 0; String test = new String(raw_text_buff.substring(iter)); // stucks here. raw_text_buff = test; iter = 0; was_reset = true; }else { open_char = c; } if(iter == raw_text_buff.length()) break; }else { sb.append(c); } ++iter; } } What I'm doing wrong?

  • java.util.BitSet -- set() doesn't work as expected

    - by dwhsix
    Am I missing something painfully obvious? Or does just nobody in the world actually use java.util.BitSet? The following test fails: @Test public void testBitSet() throws Exception { BitSet b = new BitSet(); b.set(0, true); b.set(1, false); assertEquals(2, b.length()); } It's really unclear to me why I don't end up with a BitSet of length 2 and the value 10. I peeked at the source for java.util.BitSet, and on casual inspection it seems to fail to make sufficient distinction between a bit that's been set false and a bit that has never been set to any value... (Note that explicitly setting the size of the BitSet in the constructor has no effect, e.g.: BitSet b = new BitSet(2);

  • Uploadify uploadSettings with scripData does not work

    - by kubilayeksioglu
    Hi everyone, I am sending a file to my Java Servlet via jQuery Uploadify, there are no problems while sending the actual file. But when I try to send some scriptData with file along, to process on Servlet it just does not send anything. Here is the JS code: $("button").click(function(){ $("#uploadify").uploadifySettings('scriptData', {'length':'0.2'}); $('#uploadify').uploadifyUpload(); }); $('#uploadify').uploadify({ 'uploader': 'assets/uploadify/uploadify.swf', 'script': 'upload', 'folder': '/uploads' }); And here is the Servlet code on the server side: out.println(res.getParameter("length")); Only output I get is null, while expecting "0.2". I just cannot get what's wrong and any kind of help will be appreciated. Thanks in advance.

  • Strange behavior of move with strings

    - by Umair Ahmed
    I am testing some enhanced string related functions with which I am trying to use move as a way to copy strings around for faster, more efficient use without delving into pointers. While testing a function for making a delimited string from a TStringList, I encountered a strange issue. The compiler referenced the bytes contained through the index when it was empty and when a string was added to it through move, index referenced the characters contained. Here is a small downsized barebone code sample:- unit UI; interface uses System.SysUtils, System.Types, System.UITypes, System.Rtti, System.Classes, System.Variants, FMX.Types, FMX.Controls, FMX.Forms, FMX.Dialogs, FMX.Layouts, FMX.Memo; type TForm1 = class(TForm) Results: TMemo; procedure FormCreate(Sender: TObject); end; var Form1: TForm1; implementation {$R *.fmx} function StringListToDelimitedString ( const AStringList: TStringList; const ADelimiter: String ): String; var Str : String; Temp1 : NativeInt; Temp2 : NativeInt; DelimiterSize : Byte; begin Result := ' '; Temp1 := 0; DelimiterSize := Length ( ADelimiter ) * 2; for Str in AStringList do Temp1 := Temp1 + Length ( Str ); SetLength ( Result, Temp1 ); Temp1 := 1; for Str in AStringList do begin Temp2 := Length ( Str ) * 2; // Here Index references bytes in Result Move ( Str [1], Result [Temp1], Temp2 ); // From here the index seems to address characters instead of bytes in Result Temp1 := Temp1 + Temp2; Move ( ADelimiter [1], Result [Temp1], DelimiterSize ); Temp1 := Temp1 + DelimiterSize; end; end; procedure TForm1.FormCreate(Sender: TObject); var StrList : TStringList; Str : String; begin // Test 1 : StringListToDelimitedString StrList := TStringList.Create; Str := ''; StrList.Add ( 'Hello1' ); StrList.Add ( 'Hello2' ); StrList.Add ( 'Hello3' ); StrList.Add ( 'Hello4' ); Str := StringListToDelimitedString ( StrList, ';' ); Results.Lines.Add ( Str ); StrList.Free; end; end. Please devise a solution and if possible, some explanation. Alternatives are welcome too.

  • C# problem with two threads and hardware access

    - by mack369
    I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

  • Unidirectional OneToMany in Doctrine 2

    - by darja
    I have two Doctrine entities looking like that: /** * @Entity * @Table(name = "Locales") */ class Locale { /** * @Id @Column(type="integer") * @GeneratedValue(strategy="IDENTITY") */ private $id; /** @Column(length=2, name="Name", type="string") */ private $code; } /** * @Entity * @Table(name = "localized") */ class LocalizedStrings { /** * @Id @Column(type="integer") * @GeneratedValue(strategy="IDENTITY") */ private $id; /** @Column(name="Locale", type="integer") */ private $locale; /** @Column(name="SomeText", type="string", length=300) */ private $someText; } I'd like to create reference between these entities. LocalizedStrings needs reference to Locale but Locale doesn't need reference to LocalizedStrings. How to write such mapping via Doctrine 2?

  • Is there a simpler way to convert a byte array to a 2-byte-size hexadecimal string?

    - by Tom Brito
    Is there a simpler way of implement this? Or a implemented method in JDK or other lib? /** * Convert a byte array to 2-byte-size hexadecimal String. */ public static String to2DigitsHex(byte[] bytes) { String hexData = ""; for (int i = 0; i < bytes.length; i++) { int intV = bytes[i] & 0xFF; // positive int String hexV = Integer.toHexString(intV); if (hexV.length() < 2) { hexV = "0" + hexV; } hexData += hexV; } return hexData; } public static void main(String[] args) { System.out.println(to2DigitsHex(new byte[] {8, 10, 12})); } the output is: "08 0A 0C" (without the spaces)

  • Calculating ComboBox DropDownWidth in C#

    - by Jim Fell
    In my application a ComboBox gets resized, so that it is smaller. How do I re-calculate the DropDownWidth property? I know how to set it, but I'd prefer to calculate the proper width because its contents changes. Preferabley, I was thinking of something along these lines: int iMaxLen = 0; foreach item in comboBoxList { iMaxLen = (item.Length > iMaxLen) ? item.Length : iMaxLen; } comboBoxList.DropDownWidth = iMaxLen; Thanks.

  • How To Create A Download Quota.

    - by snikolov
    I need to create an handy file down loader which will count the amount of bytes downloaded and stop when it has exceed a preset limit. i need to mirror some files but i only have 7 gb per moth of bandwidth and i dont want to exceed the limit. Example limits can be in bytes or number of files, each user has their own limit, as well as a limit for Download Quota itself. So if you set a limit of 2 gigabytes for Download Quota, downloads stop at 2 gigabytes, even if you have 3 users with a limit of 1 gigabyte each. if ($range) { //pass client Range header to rapidshare // _insert($range); $cookie .= "\r\nRange: $range"; $multipart = true; header("X-UR-RANGE-Range: $range"); } //octet-stream + attachment => client always stores file header('Content-type: application/octet-stream'); header('Content-Disposition: attachment; filename="' . $fn . '"'); //always included so clients know this script supports resuming header("Accept-Ranges: bytes"); //awful hack to pass rapidshare the premium cookie $user_agent = ini_get("user_agent"); ini_set("user_agent", $user_agent . "\r\nCookie: enc=$cookie"); $httphandle = fopen($url, "r"); $headers = stream_get_meta_data($httphandle); //let's check the return header of rapidshare for range / length indicators //we'll just pass these to the client foreach ($headers["wrapper_data"] as $header) { $header = trim($header); if (substr(strtolower($header), 0, strlen("content-range")) == "content-range") { // _insert($range); header($header); header("X-RS-RANGE-" . $header); $multipart = true; //content-range indicates partial download } elseif (substr(strtolower($header), 0, strlen("Content-Length")) == "content-length") { // _insert($range); header($header); header("X-RS-CL-" . $header); } } //now show the client he has a partial download if ($multipart) header('HTTP/1.1 206 Partial Content'); flush(); $download_rate = 100; while (!feof($httphandle)) { // send the current file part to the browser $var_stat = fread($httphandle, round($download_rate * 1024)); $var12 = strlen($var_stat); ////////////////////////////////// echo $var_stat; ///////////////////////////////// // flush the content to the browser flush(); // sleep one second sleep(1); }

  • Write a function that returns the longest palindrome in a given string. e.g "ccddcc" in the string "

    - by Learner
    I thought of a solution but it runs in O(n^2) time Algo 1: Steps: Its a brute force method Have 2 for loops for i = 1 to i less than array.length -1 for j=i+1 to j less than array.length This way you can get substring of every possible combination from the array Have a palindrome function which checks if a string is palindrome so for every substring (i,j) call this function, if it is a palindrome store it in a string variable If you find next palindrome substring and if it is greater than the current one, replace it with current one. Finally your string variable will have the answer Issues: 1. This algo runs in O(n^2) time. Algo 2: Reverse the string and store it in diferent array Now find the largest matching substring between both the array But this too runs in O(n^2) time Can you guys think of an algo which runs in a better time. If possible O(n) time

  • Socket : can an asynchronous Receive returns without reading all the bytes I asked for?

    - by NorthWind
    Hi; I was reading an article on Vadym Stetsiak's blog about how to transfer variable length messages with async sockets (url: http://vadmyst.blogspot.com/2008/03/part-2-how-to-transfer-fixed-sized-data.html). He says : What to expect when multiple messages arrive at the server? While dealing with multiple messages one has to remember that receive operation can return arbitrary number of bytes being read from the net. Typically that size is from 0 to specified buffer length in the Receive or BeginReceive methods. So, even if I tell BeginReceive to read 100 bytes, it may read less than that and returns??? I am developing a network-enabled software (TCP/IP), and I always receive the same exact number of bytes I asked for. I don't even understand the logic : why would Receive completes asynchronously if it didn't get every byte I asked for ... just keep waiting. Maybe it has something to do with IP vs TCP? Thank you for your help.

  • XML over HTTP with JMS and Spring

    - by Will Sumekar
    I have a legacy HTTP server where I need to send an XML file over HTTP request (POST) using Java (not browser) and the server will respond with another XML in its HTTP response. It is similar to Web Service but there's no WSDL and I have to follow the existing XML structure to construct my XML to be sent. I have done a research and found an example that matches my requirement here. The example uses HttpClient from Apache Commons. (There are also other examples I found but they use java.net networking package (like URLConnection) which is tedious so I don't want to use them). But it's also my requirement to use Spring and JMS. I know from Spring's reference that it's possible to combine HttpClient, JMS and Spring. My question is, how? Note that it's NOT in my requirement to use HttpClient. If you have a better suggestion, I'm welcome. Appreciate it. For your reference, here's the XML-over-HTTP example I've been talking about: /* * $Header: * $Revision$ * $Date$ * ==================================================================== * * Copyright 2002-2004 The Apache Software Foundation * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. * ==================================================================== * * This software consists of voluntary contributions made by many * individuals on behalf of the Apache Software Foundation.

With the following code it is possible to fit two gaussians to the peak, but can it easily be generalized to n gaussians? freq <- seq(100, 200, 0.1) signal <- 3.5*exp(-(freq-130)^2/50) + 0.2 + 1.5*exp(-(freq-120)^2/10) simsignal <- rpois(length(signal), 100*signal) + rnorm(length(signal)) plot(freq, simsignal) res <- nls(simsignal ~ bg + h1 * exp(-((freq - m1)/s1)^2) + h2 * exp(-((freq - m2)/s2)^2), start=c(bg = 4, h1 = 300, m1 = 128, s1 = 6, h2 = 200, m2 = 122, s2 = 4), trace=T) lines(freq, predict(res, freq), col='red') Another wish is a visulization of the contribution from each of the gaussians to the original peak, eg. the gaussians should be plotted side by side (instead of plotting their sum as done above).

  • Adding data in multiple tables in vb.net

    - by user225269
    This is a winform and I'm using mysql as a database, here is my code: I'm trying to add data into multiple tables. If TextBox14.Text = "" Or TextBox7.Text = "" Or TextBox10.Text = "" Then MsgBox("Please fill up the fields with a labels in bold letters!", MsgBoxStyle.Information) cn = New MySqlConnection("Server=localhost; Database=school;Uid=root;Pwd=nitoryolai123$%^;") 'provider to be used when working with access database cn.Open() cmd = New MySqlCommand("select * from parents, mother, father", cn) cmd.CommandText = "insert into parents values('" + idnum + "','" + p_contact + "','" + p_ad + "')" cmd.CommandText = "insert into mother values('" + idnum + "','" + mother + "','" + mother_occu + "')" cmd.CommandText = "insert into father values('" + idnum + "','" + father + "',''" + father_occu + "')" cmd.ExecuteNonQuery() I get this error, please help: Index and length must refer to a location within the string. Parameter name: length

  • NSLinguisticTagger on the contents of an NSTextStorage- crashing bug

    - by Remy Porter
    I'm trying to use an NSLinguisticTagger to monitor the contents of an NSTextStorage and provide some contextual information based on what the user types. To that end, I have an OverlayManager object, which wires up this relationship: -(void) setView:(NSTextView*) view { _view = view; _layout = view.layoutManager; _storage = view.layoutManager.textStorage; //get the TextStorage from the view [_tagger setString:_storage.string]; //pull the string out, this grabs the mutable version [self registerForNotificationsOn:self->_storage]; //subscribe to the willProcessEditing notification } When an edit occurs, I make sure to trap it and notify the tagger (and yes, I know I'm being annoyingly inconsistent with member access, I'm rusty on Obj-C, I'll fix it later): - (void) textStorageWillProcessEditing:(NSNotification*) notification{ if ([self->_storage editedMask] & NSTextStorageEditedCharacters) { NSRange editedRange = [self->_storage editedRange]; NSUInteger delta = [self->_storage changeInLength]; [_tagger stringEditedInRange:editedRange changeInLength:delta]; //should notify the tagger of the changes [self highlightEdits:self]; } } The highlightEdits message delegates the job out to a pool of "Overlay" objects. Each contains a block of code similar to this: [tagger enumerateTagsInRange:range scheme:NSLinguisticTagSchemeLexicalClass options:0 usingBlock:^(NSString *tag, NSRange tokenRange, NSRange sentenceRange, BOOL *stop) { if (tag == PartOfSpeech) { [self applyHighlightToRange:tokenRange onStorage:storage]; } }]; And that's where the problem is- the enumerateTagsInRange method crashes out with a message: 2014-06-04 10:07:19.692 WritersEditor[40191:303] NSMutableRLEArray replaceObjectsInRange:withObject:length:: Out of bounds This problem doesn't occur if I don't link to the mutable copy of the underlying string and instead do a [[_storage string] copy], but obviously I don't want to copy the entire backing store every time I want to do tagging. This all should be happening in the main run loop, so I don't think this is a threading issue. The NSRange I'm enumerating tags on exists both in the NSTextStorage and in the NSLinguisticTagger's view of the string. It's not even the fact that the applyHighlightToRange call adds attributes to the string, because it crashes before even reaching that line. I attempted to build a test case around the problem, but can't replicate it in those situations: - (void) testEdit { NSAttributedString* str = [[NSMutableAttributedString alloc] initWithString:@"Quickly, this is a test."]; text = [[NSTextStorage alloc] initWithAttributedString:str]; NSArray* schemes = [NSLinguisticTagger availableTagSchemesForLanguage:@"en"]; tagger = [[NSLinguisticTagger alloc] initWithTagSchemes:schemes options:0]; [tagger setString:[text string]]; [text beginEditing]; [[text mutableString] appendString:@"T"]; NSRange edited = [text editedRange]; NSUInteger length = [text changeInLength]; [text endEditing]; [tagger stringEditedInRange:edited changeInLength:length]; [tagger enumerateTagsInRange:edited scheme:NSLinguisticTagSchemeLexicalClass options:0 usingBlock:^(NSString *tag, NSRange tokenRange, NSRange sentenceRange, BOOL *stop) { //doesn't matter, this should crash }]; } That code doesn't crash.

  • Perl Hash Slice, Replication x Operator, and sub params

    - by user210757
    Ok, I understand perl hash slices, and the "x" operator in Perl, but can someone explain the following code example from here (slightly simplified)? sub test{ my %hash; @hash{@_} = (undef) x @_; } Example Call to sub: test('one', 'two', 'three'); This line is what throws me: @hash{@_} = (undef) x @_; It is creating a hash where the keys are the parameters to the sub and initializing to undef, so: %hash: 'one' = undef, 'two' = undef, 'three' = undef The rvalue of the x operator should be a number; how is it that @_ is interpreted as the length of the sub's parameter array? I would expect you'd at least have to do this: @hash{@_} = (undef) x length(@_);
