• asp.net labels and asp.net textboxes are not lining up correctly?

  - by Xaisoft

  My Registration page currently looks like the following: The current styling I have for the above is image is: <style type="text/css"> #contactinfo label { float: left; width: 10em; margin-right: 0.5em; text-align: right; font-size: 14px; } #contactinfo p { padding: 5px; } #contactinfo input[type="text"], input[type="password"] { height: 1.5em; } #contactinfo select { padding: 0.25em; } #contactinfo input[type="text"]:focus, input[type="password"]:focus { background-color: #FFFFE0; } #contactinfo .update { margin-left: 12.5em; } #contactinfo .error { background-color: transparent; } #contactinfo .longtextbox { width: 20em; } #contactinfo .shorttextbox { width: 5em; } </style> and the markup is <div id="contactinfo"> <p> <asp:Label runat="server" AssociatedControlID="txtEmail">Email </asp:Label> <asp:TextBox ID="txtEmail" runat="server" CssClass="longtextbox" /> </p> <p> <asp:Label runat="server" AssociatedControlID="txtFirstName">First Name </asp:Label> <asp:TextBox ID="txtFirstName" runat="server" ValidationGroup="AccountValidation" /> <asp:RequiredFieldValidator runat="server" ControlToValidate="txtFirstName" Text="First Name is required."

I want to get city, state, and zip all on the same line, but as soon as I move all the labels and inputs for city,state,zip into one p tag, it looks like the following and I don't know how to fix it.

• Sorting/Paginating/Filtering Complex Multi-AR Object Tables in Rails

  - by Matt Rogish

  I have a complex table pulled from a multi-ActiveRecord object array. This listing is a combined display of all of a particular user's "favorite" items (songs, messages, blog postings, whatever). Each of these items is a full-fledged AR object. My goal is to present the user with a simplified search, sort, and pagination interface. The user need not know that the Song has a singer, and that the Message has an author -- to the end user both entries in the table will be displayed as "User". Thus, the search box will simply be a dropdown list asking them which to search on (User name, created at, etc.). Internally, I would need to convert that to the appropriate object search, combine the results, and display. I can, separately, do pagination (mislav will_paginate), sorting, and filtering, but together I'm having some problems combining them. For example, if I paginate the combined list of items, the pagination plugin handles it just fine. It is not efficient since the pagination is happening in the app vs. the DB, but let's assume the intended use-case would indicate the vast majority of the users will have less than 30 favorited items and all other behavior, server capabilities, etc. indicates this will not be a bottleneck. However, if I wish to sort the list I cannot sort it via the pagination plugin because it relies on the assumption that the result set is derived from a single SQL query, and also that the field name is consistent throughout. Thus, I must sort the merged array via ruby, e.g. @items.sort_by{ |i| i.whatever } But, since the items do not share common names, I must first interrogate the object and then call the correct sort by. For example, if the user wishes to sort by user name, if the sorted object is a message, I sort by author but if the object is a song, I sort by singer. This is all very gross and feels quite un-ruby-like. This same problem comes into play with the filter. If the user filters on the "parent item" (the message's thread, the song's album), I must translate that to the appropriate collection object method. Also gross. This is not the exact set-up but is close enough. Note that this is a legacy app so changing it is quite difficult, although not impossible. Also, yes there is some DRY that can be done, but don't focus on the style or elegance of the following code. Style/elegance of the SOLUTION is important, however! :D models: class User < ActiveRecord::Base ... has_and_belongs_to_many :favorite_messages, :class_name => "Message" has_and_belongs_to_many :favorite_songs, :class_name => "Song" has_many :authored_messages, :class_name => "Message" has_many :sung_songs, :class_name => "Song" end class Message < ActiveRecord::Base has_and_belongs_to_many :favorite_messages belongs_to :author, :class_name => "User" belongs_to :thread end class Song < ActiveRecord::Base has_and_belongs_to_many :favorite_songs belongs_to :singer, :class_name => "User" belongs_to :album end controller: def show u = User.find 123 @items = Array.new @items << u.favorite_messages @items << u.favorite_songs # etc. etc. @items.flatten! @items = @items.sort_by{ |i| i.created_at } @items = @items.paginate :page => params[:page], :per_page => 20 end def search # Assume user is searching for username like 'Bob' u = User.find 123 @items = Array.new @items << u.favorite_messages.find( :all, :conditions => "LOWER( author ) LIKE LOWER('%bob%')" ) @items << u.favorite_songs.find( :all, :conditions => "LOWER( singer ) LIKE ... " ) # etc. etc. @items.flatten! @items = @items.sort_by{ |i| determine appropriate sorting based on user selection } @items = @items.paginate :page => params[:page], :per_page => 20 end view: #index.html.erb ... <table> <tr> <th>Title (sort ASC/DESC links)</th> <th>Created By (sort ASC/DESC links))</th> <th>Collection Title (sort ASC/DESC links)</th> <th>Created At (sort ASC/DESC links)</th> </tr> <% @items.each |item| do %> <%= render { :partial => "message", :locals => item } if item.is_a?

• C# Reading and Writing a Char[] to and from a Byte[] - Updated with Solution

  - by Simon G

  Hi, I have a byte array of around 10,000 bytes which is basically a blob from delphi that contains char, string, double and arrays of various types. This need to be read in and updated via C#. I've created a very basic reader that gets the byte array from the db and converts the bytes to the relevant object type when accessing the property which works fine. My problem is when I try to write to a specific char[] item, it doesn't seem to update the byte array. I've created the following extensions for reading and writing: public static class CharExtension { public static byte ToByte( this char c ) { return Convert.ToByte( c ); } public static byte ToByte( this char c, int position, byte[] blob ) { byte b = c.ToByte(); blob[position] = b; return b; } } public static class CharArrayExtension { public static byte[] ToByteArray( this char[] c ) { byte[] b = new byte[c.Length]; for ( int i = 1; i < c.Length; i++ ) { b[i] = c[i].ToByte(); } return b; } public static byte[] ToByteArray( this char[] c, int positon, int length, byte[] blob ) { byte[] b = c.ToByteArray(); Array.Copy( b, 0, blob, positon, length ); return b; } } public static class ByteExtension { public static char ToChar( this byte[] b, int position ) { return Convert.ToChar( b[position] ); } } public static class ByteArrayExtension { public static char[] ToCharArray( this byte[] b, int position, int length ) { char[] c = new char[length]; for ( int i = 0; i < length; i++ ) { c[i] = b.ToChar( position ); position += 1; } return c; } } to read and write chars and char arrays my code looks like: Byte[] _Blob; // set from a db field public char ubin { get { return _tariffBlob.ToChar( 14 ); } set { value.ToByte( 14, _Blob ); } } public char[] usercaplas { get { return _tariffBlob.ToCharArray( 2035, 10 ); } set { value.ToByteArray( 2035, 10, _Blob ); } } So to write to the objects I can do: ubin = 'C'; // this will update the byte[] usercaplas = new char[10] { 'A', 'B', etc. }; // this will update the byte[] usercaplas[3] = 'C'; // this does not update the byte[] I know the reason is that the setter property is not being called but I want to know is there a way around this using code similar to what I already have? I know a possible solution is to use a private variable called _usercaplas that I set and update as needed however as the byte array is nearly 10,000 bytes in length the class is already long and I would like a simpler approach as to reduce the overall code length and complexity. Thank Solution Here's my solution should anyone want it. If you have a better way of doing then let me know please. First I created a new class for the array: public class CharArrayList : ArrayList { char[] arr; private byte[] blob; private int length = 0; private int position = 0; public CharArrayList( byte[] blob, int position, int length ) { this.blob = blob; this.length = length; this.position = position; PopulateInternalArray(); SetArray(); } private void PopulateInternalArray() { arr = blob.ToCharArray( position, length ); } private void SetArray() { foreach ( char c in arr ) { this.Add( c ); } } private void UpdateInternalArray() { this.Clear(); SetArray(); } public char this[int i] { get { return arr[i]; } set { arr[i] = value; UpdateInternalArray(); } } } Then I created a couple of extension methods to help with converting to a byte[] public static byte[] ToByteArray( this CharArrayList c ) { byte[] b = new byte[c.Count]; for ( int i = 0; i < c.Count; i++ ) { b[i] = Convert.ToChar( c[i] ).ToByte(); } return b; } public static byte[] ToByteArray( this CharArrayList c, byte[] blob, int position, int length ) { byte[] b = c.ToByteArray(); Array.Copy( b, 0, blob, position, length ); return b; } So to read and write to the object: private CharArrayList _usercaplass; public CharArrayList usercaplas { get { if ( _usercaplass == null ) _usercaplass = new CharArrayList( _tariffBlob, 2035, 100 ); return _usercaplass; } set { _usercaplass = value; _usercaplass.ToByteArray( _tariffBlob, 2035, 100 ); } } As mentioned before its not an ideal solutions as I have to have private variables and extra code in the setter but I couldnt see a way around it.

• How to implement Cocoa copyWithZone on derived object in MonoMac C#?

  - by Justin Aquadro

  I'm currently porting a small Winforms-based .NET application to use a native Mac front-end with MonoMac. The application has a TreeControl with icons and text, which does not exist out of the box in Cocoa. So far, I've ported almost all of the ImageAndTextCell code in Apple's DragNDrop example: https://developer.apple.com/library/mac/#samplecode/DragNDropOutlineView/Listings/ImageAndTextCell_m.html#//apple_ref/doc/uid/DTS40008831-ImageAndTextCell_m-DontLinkElementID_6, which is assigned to an NSOutlineView as a custom cell. It seems to be working almost perfectly, except that I have not figured out how to properly port the copyWithZone method. Unfortunately, this means the internal copies that NSOutlineView is making do not have the image field, and it leads to the images briefly vanishing during expand and collapse operations. The objective-c code in question is: - (id)copyWithZone:(NSZone *)zone { ImageAndTextCell *cell = (ImageAndTextCell *)[super copyWithZone:zone]; // The image ivar will be directly copied; we need to retain or copy it. cell->image = [image retain]; return cell; } The first line is what's tripping me up, as MonoMac does not expose a copyWithZone method, and I don't know how to otherwise call it. Update Based on current answers and additional research and testing, I've come up with a variety of models for copying an object. static List<ImageAndTextCell> _refPool = new List<ImageAndTextCell>(); // Method 1 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 2 [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); return cell; } [Export("dealloc")] public void Dealloc () { _refPool.Remove(this); this.Dispose(); } // Method 3 static IntPtr selRetain = Selector.GetHandle ("retain"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell() { Title = Title, Image = Image, }; _refPool.Add(cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } // Method 4 static IntPtr selRetain = Selector.GetHandle ("retain"); static IntPtr selRetainCount = Selector.GetHandle("retainCount"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone (IntPtr zone) { ImageAndTextCell cell = new ImageAndTextCell () { Title = Title, Image = Image, }; _refPool.Add (cell); Messaging.void_objc_msgSend (cell.Handle, selRetain); return cell; } public void PeriodicCleanup () { List<ImageAndTextCell> markedForDelete = new List<ImageAndTextCell> (); foreach (ImageAndTextCell cell in _refPool) { uint count = Messaging.UInt32_objc_msgSend (cell.Handle, selRetainCount); if (count == 1) markedForDelete.Add (cell); } foreach (ImageAndTextCell cell in markedForDelete) { _refPool.Remove (cell); cell.Dispose (); } } // Method 5 static IntPtr selCopyWithZone = Selector.GetHandle("copyWithZone:"); [Export("copyWithZone:")] public virtual NSObject CopyWithZone(IntPtr zone) { IntPtr copyHandle = Messaging.IntPtr_objc_msgSendSuper_IntPtr(SuperHandle, selCopyWithZone, zone); ImageAndTextCell cell = new ImageAndTextCell(copyHandle) { Image = Image, }; _refPool.Add(cell); return cell; } Method 1: Increases the retain count of the unmanaged object. The unmanaged object will persist persist forever (I think? dealloc never called), and the managed object will be harvested early. Seems to be lose-lose all-around, but runs in practice. Method 2: Saves a reference of the managed object. The unmanaged object is left alone, and dealloc appears to be invoked at a reasonable time by the caller. At this point the managed object is released and disposed. This seems reasonable, but on the downside the base type's dealloc won't be run (I think?) Method 3: Increases the retain count and saves a reference. Unmanaged and managed objects leak forever. Method 4: Extends Method 3 by adding a cleanup function that is run periodically (e.g. during Init of each new ImageAndTextCell object). The cleanup function checks the retain counts of the stored objects. A retain count of 1 means the caller has released it, so we should as well. Should eliminate leaking in theory. Method 5: Attempt to invoke the copyWithZone method on the base type, and then construct a new ImageAndTextView object with the resulting handle. Seems to do the right thing (the base data is cloned). Internally, NSObject bumps the retain count on objects constructed like this, so we also use the PeriodicCleanup function to release these objects when they're no longer used. Based on the above, I believe Method 5 is the best approach since it should be the only one that results in a truly correct copy of the base type data, but I don't know if the approach is inherently dangerous (I am also making some assumptions about the underlying implementation of NSObject). So far nothing bad has happened "yet", but if anyone is able to vet my analysis then I would be more confident going forward.

• MVC 3 Remote Validation jQuery error on submit

  - by Richard Reddy

  I seem to have a weird issue with remote validation on my project. I am doing a simple validation check on an email field to ensure that it is unique. I've noticed that unless I put the cursor into the textbox and then remove it to trigger the validation at least once before submitting my form I will get a javascript error. e[h] is not a function jquery.min.js line 3 If I try to resubmit the form after the above error is returned everything works as expected. It's almost like the form tried to submit before waiting for the validation to return or something. Am I required to silently fire off a remote validation request on submit before submitting my form? Below is a snapshot of the code I'm using: (I've also tried GET instead of POST but I get the same result). As mentioned above, the code works fine but the form returns a jquery error unless the validation is triggered at least once. Model: public class RegisterModel { [Required] [Remote("DoesUserNameExist", "Account", HttpMethod = "POST", ErrorMessage = "User name taken.")] [Display(Name = "User name")] public string UserName { get; set; } [Required] [Display(Name = "Firstname")] public string Firstname { get; set; } [Display(Name = "Surname")] public string Surname { get; set; } [Required] [Remote("DoesEmailExist", "Account", HttpMethod = "POST", ErrorMessage = "Email taken.", AdditionalFields = "UserName")] [Display(Name = "Email address")] public string Email { get; set; } [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] [DataType(DataType.Password)] [Display(Name = "Confirm password")] public string ConfirmPassword { get; set; } [Display(Name = "Approved?")] public bool IsApproved { get; set; } } public class UserRoleModel { [Display(Name = "Assign Roles")] public IEnumerable<RoleViewModel> AllRoles { get; set; } public RegisterModel RegisterUser { get; set; } } Controller: // POST: /Account/DoesEmailExist // passing in username so that I can ignore the same email address for the same user on edit page [HttpPost] public JsonResult DoesEmailExist([Bind(Prefix = "RegisterUser.Email")]string Email, [Bind(Prefix = "RegisterUser.UserName")]string UserName) { var user = Membership.GetUserNameByEmail(Email); if (!String.IsNullOrEmpty(UserName)) { if (user == UserName) return Json(true); } return Json(user == null); } View: <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.17/jquery-ui.min.js" type="text/javascript"></script> <script type="text/javascript" src="/Content/web/js/jquery.unobtrusive-ajax.min.js"></script> <script type="text/javascript" src="/Content/web/js/jquery.validate.min.js"></script> <script type="text/javascript" src="/Content/web/js/jquery.validate.unobtrusive.min.js"></script> ...... @using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class="titleh"> <h3>Edit a user account</h3> </div> <div class="body"> @Html.HiddenFor(model => model.RegisterUser.UserName) @Html.Partial("_CreateOrEdit", Model) <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(model => model.RegisterUser.IsApproved)</span> @Html.RadioButtonFor(model => model.RegisterUser.IsApproved, true, new { @class = "uniform" }) Active @Html.RadioButtonFor(model => model.RegisterUser.IsApproved, false, new { @class = "uniform" }) Disabled <div class="clear"></div> </div> <div class="button-box"> <input type="submit" name="submit" value="Save" class="st-button"/> @Html.ActionLink("Back to List", "Index", null, new { @class = "st-clear" }) </div> </div> } CreateEdit Partial View @model Project.Domain.Entities.UserRoleModel <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Firstname)</span> @Html.TextBoxFor(m => m.RegisterUser.Firstname, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Firstname) <div class="clear"></div> </div> <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Surname)</span> @Html.TextBoxFor(m => m.RegisterUser.Surname, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Surname) <div class="clear"></div> </div> <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Email)</span> @Html.TextBoxFor(m => m.RegisterUser.Email, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Email) <div class="clear"></div> </div> Thanks, Rich

• pass an ID with hyperlik but cant get this ID value from a fk in one table when i click in insert

  - by susan

  Something strange happened in my codes, actually I have a hyperlink that pass ID value in a query string to second page.in second page i have 2 sql datasource that both these sql datasources should get this id value and pass it to a filter parameter to show sth in datalist. so in another word I have a first page that has an hyperlink read ID value from a datasource and pass it to second page.its like below: <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# "~/forumpage.aspx?ID="+Eval("ID")%>'><%#Eval("title")%> </asp:HyperLink> then in second page i have one sql datasource with a query like this ...where ID=@id and get this id in query string from db.it work great . but i have problem with second sql datasource in second page it has a query sth like below:...forms.question_id=@id then in sql reference both to query string as ID that get by first page in hyperlink. but when i click in insert button show me error with fk. error:Error:The INSERT statement conflicted with the FOREIGN KEY constraint "FK_forumreply_forumquestions". The conflict occurred in database "forum", table "dbo.forumquestions", column 'ID'. The statement has been terminated. my tables (question(ID,user_id(fk),Cat_id(fk),title,bodytext) (reply(ID,userr_id(fk),questionn_id(fk),titlereply,bodytestreply); When by hand in cb i gave a number in questionn_id like 1 it show me successful but when it want read from a filter by datasource this field face with problem. plzzzz help i really need skip from this part.and cause i am new i guess I cant understand the logic way clearly. <asp:SqlDataSource ID="sdsreply" runat="server" ConnectionString="<%$ ConnectionStrings:forumConnectionString %>" SelectCommand="SELECT forumreply.ID, forumreply.userr_id, forumreply.questionn_id, forumreply.bodytextreply, forumreply.datetimereply, forumquestions.ID AS Expr1, forumusers.ID AS Expr2, forumusers.username FROM forumquestions INNER JOIN forumreply ON forumquestions.ID = forumreply.questionn_id INNER JOIN forumusers ON forumquestions.user_id = forumusers.ID AND forumreply.userr_id = forumusers.ID where forumreply.questionn_id=@questionn_id"> <SelectParameters> <asp:QueryStringParameter Name="questionn_id" QueryStringField="ID" /> </SelectParameters> </asp:SqlDataSource> it is cb for second page in insert button: { if (Session["userid"] != null) { lblreply.Text = Session["userid"].ToString(); } else { Session["userid"]=null; } if (HttpContext.Current.User.Identity.IsAuthenticated) { lblshow.Text = string.Empty; string d = HttpContext.Current.User.Identity.Name; lblshow.Text =d + "???? ??? ?????." ; foreach (DataListItem item in DataList2.Items) { Label questionn_idLabel = (Label)item.FindControl("questionn_idLabel"); Label userr_idLabel = (Label)item.FindControl("userr_idLabel"); lbltest.Text = string.Empty; lbltest.Text = questionn_idLabel.Text; lblreply.Text = string.Empty; lblreply.Text = userr_idLabel.Text; } } else { lblshow.Text = "??? ??? ??? ??? ?? ?? ?????? ???? ???? ???? ????? ??? ??? ? ??? ????? ???????."; } } { if(HttpContext.Current.User.Identity.IsAuthenticated) { if (Page.IsValid) { SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["forumConnectionString"].ConnectionString); try { con.Open(); SqlCommand cmd = new SqlCommand("insert into forumreply (userr_id,questionn_id,bodytextreply,datetimereply)values(@userr_id,@questionn_id,@bodytextreply,@datetimereply)", con); cmd.Parameters.AddWithValue("userr_id",lblreply.Text); cmd.Parameters.AddWithValue("questionn_id",lbltest.Text); cmd.Parameters.AddWithValue("bodytextreply",txtbody.Text); cmd.Parameters.AddWithValue("datetimereply",DateTime.Now ); cmd.ExecuteNonQuery(); } catch (Exception exp) { Response.Write("<b>Error:</b>"); Response.Write(exp.Message); } finally { con.Close(); } lblmsg.Text = "???? ??? ?? ?????? ??? ?????.thx"; lblshow.Visible = false; //lbltxt.Text = txtbody.Text; txtbody.Text = string.Empty; } } else { lblmsg.Text = string.Empty; Session["rem"] = Request.UrlReferrer.AbsoluteUri; Response.Redirect("~/login.aspx"); } }

• Service injection into Controller (Spring MVC)

  - by ThaSaleni

  Hi I have a Spring web application, I have built it up to the controller stage and I could inject my Daos, into my Services fine. Now when I want to inject my Service into my controller i get an error for dependency with the Dao and further down the sessionFactory. I don't want to inject these again cause this will ultimately lead me to eventually create a data source but I have my Daos for data access and they already know about sessionFactory. Am I missing something here? here's the sample code snippets My Service: @Service("productService") @Transactional public class ProductServiceImpl implements ProductService { private ProductDao productDao; @Autowired public void setDao(ProductDao productDao) { this.productDao = productDao; } My Controller @Controller @WebServlet(name="controllerServlet", loadOnStartup= urlPatterns=...}) public class ControllerServlet extends HttpServlet { boolean isUserLogedIn =false; @Autowired private ProductService productService; public void setProductService(ProductService productService){ this.productService = productService; } Servlet-context Stack trace javax.servlet.ServletException: Servlet.init() for servlet mvcServlet threw exception org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:98) org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:927) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:999) org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java: 565) org.apache.tomcat.util.net.AprEndpoint$SocketProcessor.run(AprEndpoint.java:1812) java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) java.lang.Thread.run(Thread.java:662) root cause org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'controllerServlet': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.phumzile.acme.services.ProductService com.phumzile.acme.client.web.controller.ControllerServlet.productService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.phumzile.acme.services.ProductService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

• Help modify a javascript code to perform a div scroll

  - by Jamex

  Hi, The code below uses javascript to smoothly scroll content in a div. I don't need the smooth scrolling action, and only need the onclick action for the buttons. I would like to use this code so that if a scroll up/down button is pressed, the scroll would instantaneously jump up/down to a position, just like if you were to press the reset button (see demo link). If the down button is pressed, it would jump down the position of the content div (say 300px) and show the text instantaneously without showing how the scrolling text. I am not familiar with JS, so it you know a shorter way, please suggest. TIA the demo link is HERE The code is > this.easyscroll = function(){ // id of the container element var > id = "myContent"; // navigation > buttons text var nav = ["Scroll Up", > "Scroll Down", "Reset"]; // id for > each navigation button (OPTIONAL) var > navId = ["btnUp", "btnDown", > "btnReset"]; > > // movement speed var speed = 5; > // desired height of the container > element (in pixels) var height = 200; > // // END CONFIG // do not edit > below this line (unless you want to of > course :) ) // > > var obj = > document.getElementById(id); obj.up > = false; obj.down = false; obj.fast = false; > > var container = > document.createElement("div"); var > parent = obj.parentNode; > container.id="easyscroll"; > parent.insertBefore(container,obj); > parent.removeChild(obj); > container.style.position = > "relative"; container.style.height = > height + "px"; > container.style.overflow = "hidden"; > obj.style.position = "absolute"; > obj.style.top = "0"; obj.style.left > = "0"; container.appendChild(obj); var btns = new Array(); var ul = > document.createElement("ul"); > ul.id="easyscrollnav"; for (var > i=0;i<nav.length;i++){ var li = > document.createElement("li"); > li.innerHTML = nav[i]; li.id = > navId[i]; btns.push(li); > ul.appendChild(li); }; > parent.insertBefore(ul,container); > btns[0].onmouseover = function(){ > obj.up = true; this.className = > "over"; }; btns[0].onmouseout = > function(){ obj.up = false; > this.className = ""; }; > btns[1].onmouseover = function(){ > obj.down = true; this.className = > "over"; }; btns[1].onmouseout = > function(){ obj.down = false; > this.className = ""; }; > btns[0].onmousedown = > btns[1].onmousedown = function(){ > obj.fast = true; }; > btns[0].onmouseup = btns[1].onmouseup > = function(){ obj.fast = false; }; btns[2].onmouseover = > function(){ this.className = > "over"; }; btns[2].onmouseout = > function(){ this.className = ""; > }; btns[2].onclick = function(){ > obj.style.top = "0px"; }; > this.start = function(){ var newTop; var objHeight = > obj.offsetHeight; var top = > obj.offsetTop; var fast = (obj.fast) > ? 2 : 1; if(obj.down){ newTop > = ((objHeight+top) > height) ? top-(speed*fast) : top; > obj.style.top = newTop + "px"; > }; if(obj.up){ newTop = > (top < 0) ? top+(speed*fast) : top; > obj.style.top = newTop + "px"; }; > }; obj.interval = > setInterval("start()",50); }; > > > this.addEvent = function(obj,type,fn){ > if(obj.attachEvent){ > obj['e'+type+fn] = fn; > obj[type+fn] = > function(){obj['e'+type+fn](window.event > );} obj.attachEvent('on'+type, > obj[type+fn]); } else { > obj.addEventListener(type,fn,false); > }; }; > addEvent(window,"load",easyscroll);

• System.Timers.Timer leaking due to "direct delegate roots"

  - by alimbada

  Apologies for the rather verbose and long-winded post, but this problem's been perplexing me for a few weeks now so I'm posting as much information as I can in order to get this resolved quickly. We have a WPF UserControl which is being loaded by a 3rd party app. The 3rd party app is a presentation application which loads and unloads controls on a schedule defined by an XML file which is downloaded from a server. Our control, when it is loaded into the application makes a web request to a web service and uses the data from the response to display some information. We're using an MVVM architecture for the control. The entry point of the control is a method that is implementing an interface exposed by the main app and this is where the control's configuration is set up. This is also where I set the DataContext of our control to our MainViewModel. The MainViewModel has two other view models as properties and the main UserControl has two child controls. Depending on the data received from the web service, the main UserControl decides which child control to display, e.g. if there is a HTTP error or the data received is not valid, then display child control A, otherwise display child control B. As you'd expect, these two child controls bind two separate view models each of which is a property of MainViewModel. Now child control B (which is displayed when the data is valid) has a RefreshService property/field. RefreshService is an object that is responsible for updating the model in a number of ways and contains 4 System.Timers.Timers; a _modelRefreshTimer a _viewRefreshTimer a _pageSwitchTimer a _retryFeedRetrievalOnErrorTimer (this is only enabled when something goes wrong with retrieving data). I should mention at this point that there are two types of data; the first changes every minute, the second changes every few hours. The controls' configuration decides which type we are using/displaying. If data is of the first type then we update the model quite frequently (every 30 seconds) using the _modelRefreshTimer's events. If the data is of the second type then we update the model after a longer interval. However, the view still needs to be refreshed every 30 seconds as stale data needs to be removed from the view (hence the _viewRefreshTimer). The control also paginates the data so we can see more than we can fit on the display area. This works by breaking the data up into Lists and switching the CurrentPage (which is a List) property of the view model to the right List. This is done by handling the _pageSwitchTimer's Elapsed event. Now the problem My problem is that the control, when removed from the visual tree doesn't dispose of it's timers. This was first noticed when we started getting an unusually high number of requests on the web server end very soon after deploying this control and found that requests were being made at least once a second! We found that the timers were living on and not stopping hours after the control had been removed from view and that the more timers there were the more requests piled up at the web server. My first solution was to implement IDisposable for the RefreshService and do some clean up when the control's UnLoaded event was fired. Within the RefreshServices Dispose method I've set Enabled to false for all the timers, then used the Stop() method on all of them. I've then called Dispose() too and set them to null. None of this worked. After some reading around I found that event handlers may hold references to Timers and prevent them from being disposed and collected. After some more reading and researching I found that the best way around this was to use the Weak Event Pattern. Using this blog and this blog I've managed to work around the shortcomings in the Weak Event pattern. However, none of this solves the problem. Timers are still not being disabled or stopped (let alone disposed) and web requests are continuing to build up. Mem Profiler tells me that "This type has N instances that are directly rooted by a delegate. This can indicate the delegate has not been properly removed" (where N is the number of instances). As far as I can tell though, all listeners of the Elapsed event for the timers are being removed during the cleanup so I can't understand why the timers continue to run. Thanks for reading. Eagerly awaiting your suggestions/comments/solutions (if you got this far :-p)

• How to programatically read native DLL imports in C#?

  - by Eric

  The large hunk of C# code below is intended to print the imports of a native DLL. I copied it from from this link and modified it very slightly, just to use LoadLibraryEx as Mike Woodring does here. I find that when I call the Foo.Test method with the original example's target, MSCOREE.DLL, it prints all the imports fine. But when I use other dlls like GDI32.DLL or WSOCK32.DLL the imports do not get printed. What's missing from this code that would let it print all the imports as, for example, DUMPBIN.EXE does? (Is there a hint I'm not grokking in the original comment that says, "using mscoree.dll as an example as it doesnt export any thing"?) Here's the extract that just shows how it's being invoked: public static void Test() { // WORKS: var path = @"c:\windows\system32\mscoree.dll"; // NO ERRORS, BUT NO IMPORTS PRINTED EITHER: //var path = @"c:\windows\system32\gdi32.dll"; //var path = @"c:\windows\system32\wsock32.dll"; var hLib = LoadLibraryEx(path, 0, DONT_RESOLVE_DLL_REFERENCES | LOAD_IGNORE_CODE_AUTHZ_LEVEL); TestImports(hLib, true); } And here is the whole code example: namespace PETest2 { [StructLayout(LayoutKind.Explicit)] public unsafe struct IMAGE_IMPORT_BY_NAME { [FieldOffset(0)] public ushort Hint; [FieldOffset(2)] public fixed char Name[1]; } [StructLayout(LayoutKind.Explicit)] public struct IMAGE_IMPORT_DESCRIPTOR { #region union /// <summary> /// CSharp doesnt really support unions, but they can be emulated by a field offset 0 /// </summary> [FieldOffset(0)] public uint Characteristics;

• reCaptcha integration with php

  - by Neil Bradley

  Hi there, I'm building a contact us page that also uses a reCaptcha, but im having a few issues with it. I fill in all of the fields in the contact form and the correct reCaptcha words, but the form does not submit. I'm assuming this is something to do with the validation, but wondered if someone might be able to spot where i'm going wrong? The PHP code at the top of my page looks like this; <?php include('includes/session.php'); $err = ''; $success = ''; if(isset($_POST["docontact"]) && $_POST["docontact"] == "yes") { //get form details $form = new stdClass(); $form->name = sanitizeOne($_POST["name"], "str"); $form->email = sanitizeOne($_POST["email"], "str"); $form->phone = sanitizeOne($_POST["phone"], "str"); $form->mysevenprog = sanitizeOne($_POST["mysevenprog"], "str"); $form->enquiry = sanitizeOne($_POST["enquiry"], "str"); $form->howfindsite = sanitizeOne($_POST["howfindsite"], "str"); //Check for errors (required: name, email, enquiry) if($form->name == "") { $err .= '<p class="warning">Please enter your name!</p>'; } if($form->email == "") { $err .= '<p class="warning">Please enter your email address!</p>'; } if($form->enquiry == "") { $err .= '<p class="warning">Please supply an enquiry message!</p>'; } //Send Email if($err == "") { $mailer = new BlueMailer(); $mailer->AddAddress(Configuration::getVar("developer_email"), Configuration::getVar("admin_email_name")); include('templates/email/contact-us-admin.php'); if(!$mailer->Send()) { $err .= "<p>There was an error sending submitting your request!, Please try again later."; } else { $success = 'thanks'; } } } else { //Initialise empty variables $form = new stdClass(); $form->name = ""; $form->email = ""; $form->phone = ""; $form->mysevenprog = ""; $form->enquiry = ""; $form->howfindsite = ""; } ?> And then in the body of my page I have the form as follows; <?php if($err != "") : ?> <div class="error"> <?php echo $err; ?> </div> <?php endif; ?> <?php if($success == 'thanks') : ?> <h3>Thank you for your enquiry</h3> <p>Your enquiry has been successfully sent.

• Problem creating calculations 'engine' in two class java calculator

  - by tokee

  i have hit a brick wall whilst attempting to create a two class java calculator but have been unsuccessful so far in getting it working. i have the code for an interface which works and displays ok but creating a seperate class 'CalcEngine' to do the actual calculations has proven to be beyond me. I'd appreciate it if someone could kick start things for me and create a class calcEngine which works with the interface class and allows input when from single button i.e. if one is pressed on the calc then 1 displays onscreen. please note i'm not asking someone to do the whole thing for me as i want to learn and i'm confident i can do the rest including addition subtraction etc. once i get over the obstacle of getting the two classes to communicate. any and all assistance would be very much appreciated. Please see the calcInterface class code below - import java.awt.*; import javax.swing.*; import javax.swing.border.*; import java.awt.event.*; /** *A Class that operates as the framework for a calculator. *No calculations are performed in this section */ public class CalcFrame implements ActionListener { private CalcEngine calc; private JFrame frame; private JTextField display; private JLabel status; /** * Constructor for objects of class GridLayoutExample */ public CalcFrame() { makeFrame(); //calc = engine; } /** * This allows you to quit the calculator. */ // Alows the class to quit. private void quit() { System.exit(0); } // Calls the dialog frame with the information about the project. private void showAbout() { JOptionPane.showMessageDialog(frame, "Group Project", "About Calculator Group Project", JOptionPane.INFORMATION_MESSAGE); } private void makeFrame() { frame = new JFrame("Group Project Calculator"); makeMenuBar(frame); JPanel contentPane = (JPanel)frame.getContentPane(); contentPane.setLayout(new BorderLayout(8, 8)); contentPane.setBorder(new EmptyBorder( 10, 10, 10, 10)); /** * Insert a text field */ display = new JTextField(); contentPane.add(display, BorderLayout.NORTH); //Container contentPane = frame.getContentPane(); contentPane.setLayout(new GridLayout(4, 4)); JPanel buttonPanel = new JPanel(new GridLayout(4, 4)); contentPane.add(new JButton("1")); contentPane.add(new JButton("2")); contentPane.add(new JButton("3")); contentPane.add(new JButton("4")); contentPane.add(new JButton("5")); contentPane.add(new JButton("6")); contentPane.add(new JButton("7")); contentPane.add(new JButton("8")); contentPane.add(new JButton("9")); contentPane.add(new JButton("0")); contentPane.add(new JButton("+")); contentPane.add(new JButton("-")); contentPane.add(new JButton("/")); contentPane.add(new JButton("*")); contentPane.add(new JButton("=")); contentPane.add(new JButton("C")); contentPane.add(buttonPanel, BorderLayout.CENTER); //status = new JLabel(calc.getAuthor()); //contentPane.add(status, BorderLayout.SOUTH); frame.pack(); frame.setVisible(true); } /** * Create the main frame's menu bar. * The frame that the menu bar should be added to. */ private void makeMenuBar(JFrame frame) { final int SHORTCUT_MASK = Toolkit.getDefaultToolkit().getMenuShortcutKeyMask(); JMenuBar menubar = new JMenuBar(); frame.setJMenuBar(menubar); JMenu menu; JMenuItem item; // create the File menu menu = new JMenu("File"); menubar.add(menu); // create the Quit menu with a shortcut "Q" key. item = new JMenuItem("Quit"); item.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_Q, SHORTCUT_MASK)); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { quit(); } }); menu.add(item); // Adds an about menu. menu = new JMenu("About"); menubar.add(menu); // Displays item = new JMenuItem("Calculator Project"); item.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { showAbout(); } }); menu.add(item); } /** * An interface action has been performed. * Find out what it was and handle it. * @param event The event that has occured. */ public void actionPerformed(ActionEvent event) { String command = event.getActionCommand(); if(command.equals("0") || command.equals("1") || command.equals("2") || command.equals("3") || command.equals("4") || command.equals("5") || command.equals("6") || command.equals("7") || command.equals("8") || command.equals("9")) { int number = Integer.parseInt(command); calc.numberPressed(number); } else if(command.equals("+")) { calc.plus(); } else if(command.equals("-")) { calc.minus(); } else if(command.equals("=")) { calc.equals(); } else if(command.equals("C")) { calc.clear(); } else if(command.equals("?")) { } // else unknown command. redisplay(); } /** * Update the interface display to show the current value of the * calculator. */ private void redisplay() { display.setText("" + calc.getDisplayValue()); } /** * Toggle the info display in the calculator's status area between the * author and version information. */ }

  Hi all! have problems with mouseover in Mozilla and Chrome after making it work in IE, for sure I can tell you that my code woked perfectly in Chrome at least, cause thats my default browser and I used it for debuging when creating the javascipt and it worked nicely... until I tried to make it work in IE too.

• Hiding Options of a Select with JQuery

  - by Syed Abdul Rahman

  Okay, let's start with an example. Keep in mind, this is only an example. <select id = "selection1">     <option value = "1" id = "1">Number 1</option>     <option value = "2" id = "2">Number 2</option>     <option value = "3" id = "3">Number 3</option> </select> Now from here, we have a dropdown with 3 options. What I want to do now is to hide an option. Adding style = "display:none" will not help. The option would not appear in the dropdownlist, but using the arrow keys, you can still select it. Essentially, it does exactly what the code says. It isn't displayed, and it stops there. A JQuery function of $("#1").hide() will not work. Plus, I don't only want to hide the option, I want to completely remove it. Any possibility on doing so? Do I have to use parent/sibling/child elements? If so, I'm still not sure how. Any help on this would be greatly appreciated. Thanks.           Another question - It's related Ok, so I found out that there is a .remove() available in JQuery. Works well. But what if I want to bring it back? if(condition)     {     $(this).remove();     } I can loops this. Shouldn't be complicated. But the thing of which I am trying to do is this: Maximum Capacity of Class: (Input field here) Select Room: (Dropdown here) What I'd like for it to do is to update is Dropdown using a function such as .change() or .keyup. I could create the dropdown only after something is typed. At a change or a keyup, execute the dropdown accordingly. But what I am doing is this: $roomarray = mysql_query("SELECT *     FROM         (         SELECT *,         CASE         WHEN type = 'Classroom' THEN 1         WHEN type = 'Computer laboratory' THEN 2         WHEN type = 'Lecture Hall' THEN 3         WHEN type = 'Auditorium' THEN 4         END AS ClassTypeValue         FROM rooms         ) t     ORDER BY ClassTypeValue, maxppl, roomID"); echo "<select id = \"room\">"; while ($rooms = mysql_fetch_array($roomarray)) { ?> <option value=<?php echo $rooms['roomID']; ?> id=<?php echo $rooms['roomID']; ?>><?php echo $rooms['type']; echo "&nbsp;"; echo $rooms['roomID']; echo "&nbsp;("; echo $rooms['maxppl']; echo ")"; ?></option> <?php } echo "</select>"; Yes, I know it is very messy. I plan to change it later on. But the issue now is this: Can I toggle the removal of the options according to what has been typed? Is it possible to do so with a dropdown made from a loop? Because I sure as hell can't keep executing SQL Queries. Or is that even an option? Because if it's possible, I still think it's a bad one.

• Core Plot: only works ok with three plots

  I am adding a scatter plot to my app (iGear) so when the user selects one, two or three chainrings combined with a cogset on a bike, lines will show the gears meters.

I get extremely wide vertical spacing in IE 7 and the bacground color between the field sets does not work correctly. All is good in FF. My CSS is: fieldset { margin: 1.5em 0 0 0; padding: 0; border-style: none; border-top: 1px solid #BFBAB0; background-color: #FFFFFF; } legend { margin-left: 1em; color: #000000; font-weight: bold; } fieldset ol { padding: 1em 1em 0 1em; list-style: none; } fieldset li { padding-bottom: 1em; } fieldset.submit { border-style: none; } { var w = document.myform.mylist.selectedIndex; var selected_text = document.myform.mylist.options[w].text; alert(selected_text); } label em { display: block; color: #900; font-size: 85%; font-style: normal; text-transform: uppercase; } This is my html code. <div id="mainContent1"> <form name="myform"> <label for="mylist"><strong>Select an Account Type:</strong></label> <select name="mylist"><option value="traditional">Traditional Account</option> <option value="paperless">Paperless Account</option> </select> </form> <br /><a> </a> <form action="example.php"> <fieldset> <legend>Contact Details</legend> <ol> <li> <label for="name">Name:</label> <input id="name" name="name" class="text" type="text" /> <label for="name"> <em>required</em> </label> </li> <li> <label for="email">Email address:</label> <input id="email" name="email" class="text" type="text" /> <label for="name"> <em>required</em> </li> <li> <label for="phone">Telephone:</label> <input id="phone" name="phone" class="text" type="text" /> <label for="name"> <em>required</em> <ol> <li> <input id="option1" name="option1" class="checkbox" type="checkbox" value="1" /> <label for="option1">Savings</label> </li> <li> <input id="option2" name="option2" class="checkbox" type="checkbox" value="1" /> <label for="option2">Checkings</label> </li> </ol> </fieldset> <fieldset> <legend>Delivery Address</legend> <ol> <li> <label for="address1">Address 1:</label> <input id="address1" name="address1" class="text" type="text" /> </li> <li> <label for="city">City:</label> <input id="city" name="city" class="text" type="text" /> </li> <li> <label for="postcode">Zip Code:</label> <input id="postcode" name="postcode" class="text textSmall" type="text" /> </li> <li> <label for="country">Country:</label> <input id="country" name="country" class="text" type="text" /> </li> </ol> </fieldset> <fieldset class="submit"> <input class="submit" type="submit" value="Submit" /> </fieldset> <fieldset class="clear"> <input class="clear" type="clear" value="Submit" /> </fieldset> </form>

• How can I map "insert='false' update='false'" on a composite-id key-property which is also used in a one-to-many FK?

  - by Gweebz

  I am working on a legacy code base with an existing DB schema. The existing code uses SQL and PL/SQL to execute queries on the DB. We have been tasked with making a small part of the project database-engine agnostic (at first, change everything eventually). We have chosen to use Hibernate 3.3.2.GA and "*.hbm.xml" mapping files (as opposed to annotations). Unfortunately, it is not feasible to change the existing schema because we cannot regress any legacy features. The problem I am encountering is when I am trying to map a uni-directional, one-to-many relationship where the FK is also part of a composite PK. Here are the classes and mapping file... CompanyEntity.java public class CompanyEntity { private Integer id; private Set<CompanyNameEntity> names; ... } CompanyNameEntity.java public class CompanyNameEntity implements Serializable { private Integer id; private String languageId; private String name; ... } CompanyNameEntity.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.jboss.org/dtd/hibernate/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.example"> <class name="com.example.CompanyEntity" table="COMPANY"> <id name="id" column="COMPANY_ID"/> <set name="names" table="COMPANY_NAME" cascade="all-delete-orphan" fetch="join" batch-size="1" lazy="false"> <key column="COMPANY_ID"/> <one-to-many entity-name="vendorName"/> </set> </class> <class entity-name="companyName" name="com.example.CompanyNameEntity" table="COMPANY_NAME"> <composite-id> <key-property name="id" column="COMPANY_ID"/> <key-property name="languageId" column="LANGUAGE_ID"/> </composite-id> <property name="name" column="NAME" length="255"/> </class> </hibernate-mapping> This code works just fine for SELECT and INSERT of a Company with names. I encountered a problem when I tried to update and existing record. I received a BatchUpdateException and after looking through the SQL logs I saw Hibernate was trying to do something stupid... update COMPANY_NAME set COMPANY_ID=null where COMPANY_ID=? Hibernate was trying to dis-associate child records before updating them. The problem is that this field is part of the PK and not-nullable. I found the quick solution to make Hibernate not do this is to add "not-null='true'" to the "key" element in the parent mapping. SO now may mapping looks like this... CompanyNameEntity.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.jboss.org/dtd/hibernate/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="com.example"> <class name="com.example.CompanyEntity" table="COMPANY"> <id name="id" column="COMPANY_ID"/> <set name="names" table="COMPANY_NAME" cascade="all-delete-orphan" fetch="join" batch-size="1" lazy="false"> <key column="COMPANY_ID" not-null="true"/> <one-to-many entity-name="vendorName"/> </set> </class> <class entity-name="companyName" name="com.example.CompanyNameEntity" table="COMPANY_NAME"> <composite-id> <key-property name="id" column="COMPANY_ID"/> <key-property name="languageId" column="LANGUAGE_ID"/> </composite-id> <property name="name" column="NAME" length="255"/> </class> </hibernate-mapping> This mapping gives the exception... org.hibernate.MappingException: Repeated column in mapping for entity: companyName column: COMPANY_ID (should be mapped with insert="false" update="false") My problem now is that I have tryed to add these attributes to the key-property element but that is not supported by the DTD. I have also tryed changing it to a key-many-to-one element but that didn't work either. So... How can I map "insert='false' update='false'" on a composite-id key-property which is also used in a one-to-many FK?

• Problems with real-valued input deep belief networks (of RBMs)

  - by Junier

  I am trying to recreate the results reported in Reducing the dimensionality of data with neural networks of autoencoding the olivetti face dataset with an adapted version of the MNIST digits matlab code, but am having some difficulty. It seems that no matter how much tweaking I do on the number of epochs, rates, or momentum the stacked RBMs are entering the fine-tuning stage with a large amount of error and consequently fail to improve much at the fine-tuning stage. I am also experiencing a similar problem on another real-valued dataset. For the first layer I am using a RBM with a smaller learning rate (as described in the paper) and with negdata = poshidstates*vishid' + repmat(visbiases,numcases,1); I'm fairly confident I am following the instructions found in the supporting material but I cannot achieve the correct errors. Is there something I am missing? See the code I'm using for real-valued visible unit RBMs below, and for the whole deep training. The rest of the code can be found here. rbmvislinear.m: epsilonw = 0.001; % Learning rate for weights epsilonvb = 0.001; % Learning rate for biases of visible units epsilonhb = 0.001; % Learning rate for biases of hidden units weightcost = 0.0002; initialmomentum = 0.5; finalmomentum = 0.9; [numcases numdims numbatches]=size(batchdata); if restart ==1, restart=0; epoch=1; % Initializing symmetric weights and biases. vishid = 0.1*randn(numdims, numhid); hidbiases = zeros(1,numhid); visbiases = zeros(1,numdims); poshidprobs = zeros(numcases,numhid); neghidprobs = zeros(numcases,numhid); posprods = zeros(numdims,numhid); negprods = zeros(numdims,numhid); vishidinc = zeros(numdims,numhid); hidbiasinc = zeros(1,numhid); visbiasinc = zeros(1,numdims); sigmainc = zeros(1,numhid); batchposhidprobs=zeros(numcases,numhid,numbatches); end for epoch = epoch:maxepoch, fprintf(1,'epoch %d\r',epoch); errsum=0; for batch = 1:numbatches, if (mod(batch,100)==0) fprintf(1,' %d ',batch); end %%%%%%%%% START POSITIVE PHASE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% data = batchdata(:,:,batch); poshidprobs = 1./(1 + exp(-data*vishid - repmat(hidbiases,numcases,1))); batchposhidprobs(:,:,batch)=poshidprobs; posprods = data' * poshidprobs; poshidact = sum(poshidprobs); posvisact = sum(data); %%%%%%%%% END OF POSITIVE PHASE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% poshidstates = poshidprobs > rand(numcases,numhid); %%%%%%%%% START NEGATIVE PHASE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% negdata = poshidstates*vishid' + repmat(visbiases,numcases,1);% + randn(numcases,numdims) if not using mean neghidprobs = 1./(1 + exp(-negdata*vishid - repmat(hidbiases,numcases,1))); negprods = negdata'*neghidprobs; neghidact = sum(neghidprobs); negvisact = sum(negdata); %%%%%%%%% END OF NEGATIVE PHASE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% err= sum(sum( (data-negdata).^2 )); errsum = err + errsum; if epoch>5, momentum=finalmomentum; else momentum=initialmomentum; end; %%%%%%%%% UPDATE WEIGHTS AND BIASES %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% vishidinc = momentum*vishidinc + ... epsilonw*( (posprods-negprods)/numcases - weightcost*vishid); visbiasinc = momentum*visbiasinc + (epsilonvb/numcases)*(posvisact-negvisact); hidbiasinc = momentum*hidbiasinc + (epsilonhb/numcases)*(poshidact-neghidact); vishid = vishid + vishidinc; visbiases = visbiases + visbiasinc; hidbiases = hidbiases + hidbiasinc; %%%%%%%%%%%%%%%% END OF UPDATES %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% end fprintf(1, '\nepoch %4i error %f \n', epoch, errsum); end dofacedeepauto.m: clear all close all maxepoch=200; %In the Science paper we use maxepoch=50, but it works just fine. numhid=2000; numpen=1000; numpen2=500; numopen=30; fprintf(1,'Pretraining a deep autoencoder. \n'); fprintf(1,'The Science paper used 50 epochs.

• TextField breaking MOUSE_OVER in as3: only after moving it!

  - by Franz

  I'm having a really weird problem with the MOUSE_OVER event. I'm building dynamic tabs representing mp3 songs containing textfields with info and a dynamic image for the cover art. I am trying to get a simple MOUSE_OVER working over the whole tab, such that you can select the next song to play. I am using a Sprite with alpha 0 that overlays my whole tab (incl. the textFields) as a Listener for MOUSE_OVER and _OUT... I've checked by setting the alpha to something visible and it indeed covers my tab and follows it around as I move it (just making sure I'm not moving the tab without moving the hotspot). Also, I only create it once my cover art is loaded, ensuring that it will cover that too. Now, when the tab is in the top position, everything is dandy. As soon as I move the tab to make space for the next tab, the textFields break my roll behaviour... just like that noob mistake of overlaying a sprite over the one that you're listening for MouseEvents on. But... the roll area is still on top of the field, I've set selectable and mouseEnabled to false on the textFields... nothing. It is as if the mere fact of moving the whole tab now puts the textField on top of everything in my tab (whereas visually, it's still in its expected layer). I'm using pixel fonts but tried it with system fonts, same thing... at my wits end here. public function Tab(tune:Tune) { _tune = tune; mainSprite = new Sprite(); addChild(mainSprite); drawBorder(); createFormat(); placeArtist(); placeTitle(); placeAlbum(); coverArt(); } private function placeButton():void { _button = new Sprite(); _button.graphics.beginFill(0xFF000,0); _button.graphics.drawRect(0,0,229,40); _button.graphics.endFill(); _button.addEventListener(MouseEvent.MOUSE_OVER, mouseListener); _button.addEventListener(MouseEvent.MOUSE_OUT, mouseListener); _button.buttonMode = true; mainSprite.addChild(_button); } private function mouseListener(event:MouseEvent):void { switch(event.type){ case MouseEvent.MOUSE_OVER : hilite(true); break; case MouseEvent.MOUSE_OUT : hilite(false); break; } } private function createFormat():void { _format = new TextFormat(); _format.font = "FFF Neostandard"; _format.size = 8; _format.color = 0xFFFFFF; } private function placeArtist():void { var artist : TextField = new TextField(); artist.selectable = false; artist.defaultTextFormat = _format; artist.x = 41; artist.y = 3; artist.width = 135; artist.text = _tune.artist; artist.mouseEnabled = false; mainSprite.addChild(artist); } private function placeTitle():void { var title : TextField = new TextField(); title.selectable = false; title.defaultTextFormat = _format; title.x = 41; title.y = 14; title.width = 135; title.text = _tune.title; title.mouseEnabled = false; mainSprite.addChild(title); } private function placeAlbum():void { var album : TextField = new TextField(); album.selectable = false; album.defaultTextFormat = _format; album.x = 41; album.y = 25; album.width = 135; album.text = _tune.album; album.mouseEnabled = false; mainSprite.addChild(album); } private function drawBorder():void { _border = new Sprite(); _border.graphics.lineStyle(1, 0x545454); _border.graphics.drawRect (0,0,229,40); mainSprite.addChild(_border); } private function coverArt():void { _image = new Sprite(); var imageLoader : Loader = new Loader(); _loaderInfo = imageLoader.contentLoaderInfo; _loaderInfo.addEventListener(Event.COMPLETE, coverLoaded) var image:URLRequest = new URLRequest(_tune.coverArt); imageLoader.load(image); _image.x = 1.5; _image.y = 2; _image.addChild(imageLoader); } private function coverLoaded(event:Event):void { _loaderInfo.removeEventListener(Event.COMPLETE, coverLoaded); var scaling : Number = IMAGE_SIZE / _image.width; _image.scaleX = scaling; _image.scaleY = scaling; mainSprite.addChild (_image); placeButton(); } public function hilite(state:Boolean):void{ var col : ColorTransform = new ColorTransform(); if(state){ col.color = 0xFFFFFF; } else { col.color = 0x545454; } _border.transform.colorTransform = col; }

• Hibernate without primary keys generated by db?

  - by Michael Jones

  I'm building a data warehouse and want to use InfiniDB as the storage engine. However, it doesn't allow primary keys or foreign key constraints (or any constraints for that matter). Hibernate complains "The database returned no natively generated identity value" when I perform an insert. Each table is relational, and contains a unique integer column that was previously used as the primary key - I want to keep that, but just not have the constraint in the db that the column is the primary key. I'm assuming the problem is that Hibernate expects the db to return a generated key. Is it possible to override this behaviour so I can set the primary key field's value myself and keep Hibernate happy? -- edit -- Two of the mappings are as follows: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated Jun 1, 2010 2:49:51 PM by Hibernate Tools 3.2.1.GA --> <hibernate-mapping> <class name="com.example.project.Visitor" table="visitor" catalog="orwell"> <id name="id" type="java.lang.Long"> <column name="id" /> <generator class="identity" /> </id> <property name="firstSeen" type="timestamp"> <column name="first_seen" length="19" /> </property> <property name="lastSeen" type="timestamp"> <column name="last_seen" length="19" /> </property> <property name="sessionId" type="string"> <column name="session_id" length="26" unique="true" /> </property> <property name="userId" type="java.lang.Long"> <column name="user_id" /> </property> <set name="visits" inverse="true"> <key> <column name="visitor_id" /> </key> <one-to-many class="com.example.project.Visit" /> </set> </class> </hibernate-mapping> and: <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <!-- Generated Jun 1, 2010 2:49:51 PM by Hibernate Tools 3.2.1.GA --> <hibernate-mapping> <class name="com.example.project.Visit" table="visit" catalog="orwell"> <id name="id" type="java.lang.Long"> <column name="id" /> <generator class="identity" /> </id> <many-to-one name="visitor" class="com.example.project.Visitor" fetch="join" cascade="all"> <column name="visitor_id" /> </many-to-one> <property name="visitId" type="string"> <column name="visit_id" length="20" unique="true" /> </property> <property name="startTime" type="timestamp"> <column name="start_time" length="19" /> </property> <property name="endTime" type="timestamp"> <column name="end_time" length="19" /> </property> <property name="userAgent" type="string"> <column name="user_agent" length="65535" /> </property> <set name="pageViews" inverse="true"> <key> <column name="visit_id" /> </key> <one-to-many class="com.example.project.PageView" /> </set> </class> </hibernate-mapping>
