The forms I have are, MAinWindow Nursery Primary Secondary ALL THE FORMS OPEN except for the nursery form, when I enter the correct username it displays the Primary form. ANY HELP SOON char[] DBUserArray; DBUserArray=name.toCharArray(); char [] DBPassArray; DBPassArray=pass.toCharArray(); char AdminArray []=AdminUser.toCharArray(); char NurArray []=NurHead.toCharArray(); char[] PriArray =PriHead.toCharArray(); char[] SecArray=SecHead.toCharArray(); char[] input = txtpassword.getPassword(); String user=txtusername.getText(); char [] userString; userString=user.toCharArray(); if(userString.length!=DBUserArray.length && input.length!=DBPassArray.length) { JOptionPane.showMessageDialog(null, "Username and Password Wrong","User Login",JOptionPane.ERROR_MESSAGE); } else { if(userString.length!=AdminArray.length) { if(userString.length!=PriArray.length) { if(userString.length!=NurArray.length) { if(userString.length!=SecArray.length) { } else { new Secondary().setVisible(true); setVisible(false); } } else { new Nursery().setVisible(true); setVisible(false); } } else { new Primary().setVisible(true); setVisible(false); } } else { new MainWindow().setVisible(true); setVisible(false); } }

  • How to identify a particular entity's Session Factory with Fluent NHibernate and Multiple Databases

    - by Trevor
    I've already asked this question as part of an answer to another question ( see http://stackoverflow.com/questions/2655861/fluent-nhibernate-multiple-databases ) but thought it better to ask again here. My problem is this: I'm using Fluent NHibernate. My application uses multiple databases. Each database has its own entities registered (mapped) against it. The result is that have multiple Session Factories, each one relating to a single DB, and each 'containing' its own set of mapped entities. For loading entities I've created a generic Factory class that provides some standard load methods usable for any registered entity (in any DB). The problem is: The load methods need to use the correct session factory for the entity class I'm busy dealing with. How would I determine which session factory I need to use? I have all the Session Factories 'on hand' (and indexed by database name), I just need a way, knowing just the type of Entity I'm about to load, of choosing the right Session Factory to use. For example: public IBaseBusinessObject CreatePopulatedInstance(Type boType, Guid instanceKey) { IBaseBusinessObject result = null; ISessionFactory sessionFactory = GetSessionFactory(boType); using (ISession session = sessionFactory.OpenSession()) { using (session.BeginTransaction()) { result = (IBaseBusinessObject)session.Get(boType, instanceKey); } } return result; } What needs to go on in GetSessionFactory(boType) ? Thanks for reading!

  • help with eclipse debugging /or/ subclassed SimpleAdapter not calling setViewImage()

    - by edzillion
    Hi I was following the method for asynchronously loading images into a listview as outlined in evan charlton's blog here. The problem I am having is that the setViewImage function is not being called by the system: @Override public void setViewImage(final ImageView image, final String value) { if (value != null && value.length() > 0 && image instanceof RemoteImageView) { RemoteImageView riv = (RemoteImageView) image; riv.setLocalURI(API.getCacheFileName(value)); riv.setRemoteURI(value); super.setViewImage(image, R.drawable.icon); } else { image.setVisibility(View.GONE); } } I have built his example code, and setViewImage is called fine - it seems to me that the code is functionally identical. Looking into the docs it says: First, if a SimpleAdapter.ViewBinder is available, setViewValue(android.view.View, Object, String) is invoked. If the returned value is true, binding has occured. If the returned value is false and the view to bind is a TextView, setViewText(TextView, String) is invoked. If the returned value is false and the view to bind is an ImageView, setViewImage(ImageView, int) or setViewImage(ImageView, String) is invoked. If no appropriate binding can be found, an IllegalStateException is thrown. I don't really understand how to debug (in eclipse) to find out how this process is occuring, advice on how to do so would be a help. Thanks.

  • c - dereferencing issue

    - by Joe
    Hi, I have simplified an issue that I've been having trying to isolate the problem, but it is not helping. I have a 2 dimensional char array to represent memory. I want to pass a reference to that simulation of memory to a function. In the function to test the contents of the memory I just want to iterate through the memory and print out the contents on each row. The program prints out the first row and then I get seg fault. My program is as follows: #include <stdio.h> #include <stdlib.h> #include <ctype.h> #include <string.h> void test_memory(char*** memory_ref) { int i; for(i = 0; i < 3; i++) { printf("%s\n", *memory_ref[i]); } } int main() { char** memory; int i; memory = calloc(sizeof(char*), 20); for(i = 0; i < 20; i++) { memory[i] = calloc(sizeof(char), 33); } memory[0] = "Mem 0"; memory[1] = "Mem 1"; memory[2] = "Mem 2"; printf("memory[1] = %s\n", memory[1]); test_memory(&memory); return 0; } This gives me the output: memory[1] = Mem 1 Mem 0 Segmentation fault If I change the program and create a local version of the memory in the function by dereferencing the memory_ref, then I get the right output: So: #include <stdio.h> #include <stdlib.h> #include <ctype.h> #include <string.h> void test_memory(char*** memory_ref) { char** memory = *memory_ref; int i; for(i = 0; i < 3; i++) { printf("%s\n", memory[i]); } } int main() { char** memory; int i; memory = calloc(sizeof(char*), 20); for(i = 0; i < 20; i++) { memory[i] = calloc(sizeof(char), 33); } memory[0] = "Mem 0"; memory[1] = "Mem 1"; memory[2] = "Mem 2"; printf("memory[1] = %s\n", memory[1]); test_memory(&memory); return 0; } gives me the following output: memory[1] = Mem 1 Mem 0 Mem 1 Mem 2 which is what I want, but making a local version of the memory is useless because I need to be able to change the values of the original memory from the function which I can only do by dereferencing the pointer to the original 2d char array. I don't understand why I should get a seg fault on the second time round, and I'd be grateful for any advice. Many thanks Joe

  • C# How to perform a live xslt transformation on an in memory object?

    - by JL
    I have a function that takes 2 parameters : 1 = XML file, 2 = XSLT file, then performs a transformation and returns the resulting HTML. Here is the function: /// <summary> /// Will apply an XSLT style to any XML file and return the rendered HTML. /// </summary> /// <param name="xmlFileName"> /// The file name of the XML document. /// </param> /// <param name="xslFileName"> /// The file name of the XSL document. /// </param> /// <returns> /// The rendered HTML. /// </returns> public string TransformXml(string xmlFileName, string xslFileName) { var xtr = new XmlTextReader(xmlFileName) { WhitespaceHandling = WhitespaceHandling.None }; var xd = new XmlDocument(); xd.Load(xtr); var xslt = new System.Xml.Xsl.XslCompiledTransform(); xslt.Load(xslFileName); var stm = new MemoryStream(); xslt.Transform(xd, null, stm); stm.Position = 1; var sr = new StreamReader(stm); xtr.Close(); return sr.ReadToEnd(); } I want to change the function not to accept a file for the XML, but instead just an object. The object is exactly compatible with the xslt, if it was serialized to file. But I don't want to have to serialize it to a file first. So to recap : keep the xslt coming from a file, but the xml input should an object I pass and would like to generate the xml from without any file system interaction.

  • new Facebook Like button for Blogger

    - by David
    I want to add the new facebook like button to my blogger website. http://developers.facebook.com/docs/reference/plugins/like I have to pass the url to the blog posts in the iframe src tag. I can get the blogger posts url from <data:post.url/> but I can't put that in a src string because Bloggers template system is weird. I want to do this:<iframe allowTransparency='true' frameborder='0' scrolling='no' src='http://www.facebook.com/plugins/like.php?href=<data:post.url/>&amp;layout=standard&amp;show-faces=true&amp;width=450&amp;action=like&amp;colorscheme=light' style='border:none; overflow:hidden; width:450px; height:px'/>but blogger complains: "Your template could not be parsed as it is not well-formed. Please make sure all XML elements are closed properly. XML error message: The value of attribute "src" associated with an element type "null" must not contain the '<' character."

  • Detect NetStream events with AS3 Video Object (not component)

    - by JFOX
    I have created a FLV video player using the AS3 flash.media.Video object (not the FLV playback component) and I am trying to listen for meta events and Cue Points embedded in the FLV video but I am not receiving any when I trace the movie. The cue points are not being created dynamically, they are in the FLV video. Video embed code: // Initialize net stream nc = new NetConnection(); nc.connect (null); // Not using a media server. ns = new NetStream(nc); // Add video to stage vid = new Video(456,675); addChild (vid); // Add callback method for listening on // NetStream meta data client = new Object(); ns.client = client; client.onMetaData = this.nsMetaDataCallback; client.onCuePoint = this.onCuePoint; // Play video vid.attachNetStream ( ns ); ns.play ("flv/00_010.flv"); callback handlers in the same class as the above code: public function onCuePoint(info:Object):void { trace("cuePoint: time = " + info.time + " name = " + info.name + " type = " + info.type); if (ns) ns.pause(); } public function nsMetaDataCallback (mdata:Object):void { trace (mdata.duration); } Is there anything I am missing have wrong to capture events from my net stream?

  • How to use SQLErrorCodeSQLExceptionTranslator and DAO class with @Repository in Spring?

    - by GuidoMB
    I'm using Spring 3.0.2 and I have a class called MovieDAO that uses JDBC to handle the db. I have set the @Repository annotations and I want to convert the SQLException to the Spring's DataAccessException I have the following example: @Repository public class JDBCCommentDAO implements CommentDAO { static JDBCCommentDAO instance; ConnectionManager connectionManager; private JDBCCommentDAO() { connectionManager = new ConnectionManager("org.postgresql.Driver", "postgres", "postgres"); } static public synchronized JDBCCommentDAO getInstance() { if (instance == null) instance = new JDBCCommentDAO(); return instance; } @Override public Collection<Comment> getComments(User user) throws DAOException { Collection<Comment> comments = new ArrayList<Comment>(); try { String query = "SELECT * FROM Comments WHERE Comments.userId = ?"; Connection conn = connectionManager.getConnection(); PreparedStatement stmt = conn.prepareStatement(query); stmt = conn.prepareStatement(query); stmt.setInt(1, user.getId()); ResultSet result = stmt.executeQuery(); while (result.next()) { Movie movie = JDBCMovieDAO.getInstance().getLightMovie(result.getInt("movie")); comments.add(new Comment(result.getString("text"), result.getInt("score"), user, result.getDate("date"), movie)); } connectionManager.closeConnection(conn); } catch (SQLException e) { e.printStackTrace(); //CONVERT TO DATAACCESSEXCEPTION } return comments; } } I Don't know how to get the Translator and I don't want to extends any Spring class, because that is why I'm using the @Repository annotation

  • Inner join and outer join options in Entity Framework 4.0

    - by bigb
    I am using EF 4.0 and I need to implement query with one inner join and with N outer joins I started to implement this using different approaches but get into trouble at some point. Here is two examples how I started of doing this using ObjectQuery<'T' and Linq to Entity 1)Using ObjectQuery<'T' I implement flexible outer join but I don't know how to perform inner join with entity Rules in that case (by default Include("Rules") doing outer join, but i need to inner join by Id). public static IEnumerable<Race> GetRace(List<string> includes, DateTime date) { IRepository repository = new Repository(new BEntities()); ObjectQuery<Race> result = (ObjectQuery<Race>)repository.AsQueryable<Race>(); //perform outer joins with related entities if (includes != null) foreach (string include in includes) result = result.Include(include); //here i need inner join insteard of default outer join result = result.Include("Rules"); return result.ToList(); } 2)Using Linq To Entity I need to have kind of outer join(somethin like in GetRace()) where i may pass a List with entities to include) and also i need to perform correct inner join with entity Rules public static IEnumerable<Race> GetRace2(List<string> includes, DateTime date) { IRepository repository = new Repository(new BEntities()); IEnumerable<Race> result = from o in repository.AsQueryable<Race>() from b in o.RaceBetRules select new { o }); //I need here: // 1. to perform the same way inner joins with related entities like with ObjectQuery above //here i getting List<AnonymousType> which i cant cast to //IEnumerable<Race> when i did try to cast like //(IEnumerable<Race>)result.ToList(); i did get error: //Unable to cast object of type //'System.Collections.Generic.List`1[<>f__AnonymousType0`1[BetsTipster.Entity.Tip.Types.Race]]' //to type //'System.Collections.Generic.IEnumerable`1[BetsTipster.Entity.Tip.Types.Race]'. return result.ToList(); } May be someone have some ideas about that.

  • JSON VIEW using GROUP_CONCAT question

    - by Dan Beam
    Hey DBAs and overall smart dudes. I have a question for you. We use MySQL VIEWs to format our data as JSON when it's returned (as a BLOB), which is convenient (though not particularly nice on performance, but we already know this). But, I can't seem to get a particular query working right now (each row contains NULL when it should contain a created JSON object with the values of multiple JOINs). Here's the general idea: SELECT CONCAT( "{", "\"some_list\":[", GROUP_CONCAT( DISTINCT t1.id ), "],", "\"other_list\":[", GROUP_CONCAT( DISTINCT t2.id ), "],", "}" ) cool_json FROM table_name tn INNER JOIN ( some_table st ) ON st.some_id = tn.id LEFT JOIN ( another_table at, another_one ao, used_multiple_times t1 ) ON st.id = at.some_id AND at.different_id = ao.different_id AND ao.different_id = t1.id LEFT JOIN ( another_table2 at2, another_one2 ao2, used_multiple_times t2 ) ON st.id = at2.some_id AND at2.different_id = ao2.different_id AND ao2.different_id = t2.id GROUP BY tn.id ORDER BY tn.name Anybody know the problem here? Am I missing something I should be grouping by? It was working when I was only doing 1 LEFT JOIN & GROUP_CONCAT, but now with multiple JOINs / GROUP_CONCATs it's messing it up. When I move the GROUP_CONCATs from the "cool_json" field they work as expected, but I'd like my data formatted as JSON so I can decode it server-side or client-side in one step.

  • RavenDB Ids and ASP.NET MVC3 Routes

    - by goober
    Hey all, Just building a quick, simple site with MVC 3 RC2 and RavenDB to test some things out. I've been able to make a bunch of projects, but I'm curious as to how Html.ActionLink() handles a raven DB ID. My example: I have a Document called "reasons" (a reason for something, just text mostly), which has reason text and a list of links. I can add, remove, and do everything else fine via my repository. Below is the part of my razor view that lists each reason in a bulleted list, with an Edit link as the first text: @foreach(var Reason in ViewBag.ReasonsList) { <li>@Html.ActionLink("Edit", "Reasons", "Edit", new { id = Reason.Id }, null) @Reason.ReasonText</li> <ul> @foreach (var reasonlink in Reason.ReasonLinks) { <li><a href="@reasonlink.URL">@reasonlink.URL</a></li> } </ul> } The Problem This works fine, except for the edit link. While the values and code here appear to work directly (i.e the link is firing directly), RavenDB saves my document's ID as "reasons/1". So, when the URL happens and it passes the ID, the resulting route is "http://localhost:4976/Reasons/Edit/reasons/2". So, the ID is appended correctly, but MVC is interpreting it as its own route. Any suggestions on how I might be able to get around this? Do I need to create a special route to handle it or is there something else I can do?

  • MySQL: Complex Join Statement involving two tables and a third correlation table

    - by Stephen
    I have two tables that were built for two disparate systems. I have records in one table (called "leads") that represent customers, and records in another table (called "manager") that are the exact same customers but "manager" uses different fields (For example, "leads" contains an email address, and "manager" contains two fields for two different emails--either of which might be the email from "leads"). So, I've created a correlation table that contains the lead_id and manager_id. currently this correlation table is empty. I'm trying to query the "leads" table to give me records that match either "manager" email field with the single "leads" email field, while at the same time ignoring fields that have already been added to the "correlated" table. (this way I can see how many leads that match have not yet been correlated.) Here's my current, invalid SQL attempt: SELECT leads.id, manager.id FROM leads, manager LEFT OUTER JOIN correlation ON correlation.lead_id = leads.id WHERE correlation.id IS NULL AND leads.project != "someproject" AND (manager.orig_email = leads.email OR manager.dest_email = leads.email) AND leads.created BETWEEN '1999-01-01 00:00:00' AND '2010-05-10 23:59:59' ORDER BY leads.created ASC; I get the error: Unknown column 'leads.id' in 'on clause' Before you wonder: there are records in the "leads" table where leads.project != "someproject" and leads.created falls between those dates. I've included those additional parameters for completeness.

  • Slide div inside another div effect

    - by mariki
    I am trying to create sliding images effect: Online demolink text. The problem is when you click rapidly and randomly on the buttons and not wait for animation to finish causing unpredicted results and even stopping the functionality to work. (and once it stopped in the middle of 2 images...) How Can I make it work without bugs? I know that there are some other tools for that sliding like jquery and other approaches like changing the position attribute and not the scrollLeft attribute. But I want to do it as it is, with scrollLeft, if it possible of course. The Code: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Untitled Document</title> <style type="text/css"> body { padding:0px; margin:0px; } #imageContainer { width: 500px; position: relative; } #div { overflow: hidden; white-space: nowrap; } #div img { cursor: pointer; vertical-align: bottom; width: 500px; padding:0px; margin:0px; display:inline; } </style> <script type="text/javascript"> var scrollIntervalID; var currentIndex=0; function Scroll(ind){ var dir = ind ==currentIndex?0:ind<currentIndex?-1:1; var steps = Math.abs(ind-currentIndex); scrollIntervalID = setInterval(function(){ var i=(steps*10)-1; return function(){ if (i <= 0) clearInterval(scrollIntervalID); var elm = document.getElementById("div"); elm.scrollLeft +=dir * 50; i--; document.getElementById("span").innerHTML=elm.scrollLeft; } }(), 15); currentIndex=ind; } </script> </head> <body> <div id="imageContainer"> <div id="div"> <img id="image1" src="Images/pic1.jpg" width="500px"/><img id="image2" src="Images/pic2.jpg" width="500px"/><img id="image3" src="Images/pic3.jpg" width="500px"/><img id="image4" src="Images/pic4.jpg" width="500px"/> </div> </div> <div> <input type="button" value="1" onclick="Scroll(0);"/> <input type="button" value="2" onclick="Scroll(1);"/> <input type="button" value="3" onclick="Scroll(2);"/> <input type="button" value="4" onclick="Scroll(3);"/> </div> <span id="span"></span> </body> </html>

  • Why linking doesn't work in my Xtext-based DSL?

    - by reprogrammer
    The following is the Xtext grammar for my DSL. Model: variableTypes=VariableTypes predicateTypes=PredicateTypes variableDeclarations= VariableDeclarations rules=Rules; VariableType: name=ID; VariableTypes: 'var types' (variableTypes+=VariableType)+; PredicateTypes: 'predicate types' (predicateTypes+=PredicateType)+; PredicateType: name=ID '(' (variableTypes+=[VariableType|ID])+ ')'; VariableDeclarations: 'vars' (variableDeclarations+=VariableDeclaration)+; VariableDeclaration: name=ID ':' type=[VariableType|ID]; Rules: 'rules' (rules+=Rule)+; Rule: head=Head ':-' body=Body; Head: predicate=Predicate; Body: (predicates+=Predicate)+; Predicate: predicateType=[PredicateType|ID] '(' (terms+=Term)+ ')'; Term: variable=Variable; Variable: variableDeclaration=[VariableDeclaration|ID]; terminal WS: (' ' | '\t' | '\r' | '\n' | ',')+; And, the following is a program in the above DSL. var types Node predicate types Edge(Node, Node) Path(Node, Node) vars x : Node y : Node z : Node rules Path(x, y) :- Edge(x, y) Path(x, y) :- Path(x, z) Path(z, y) When I used the generated Switch class to traverse the EMF object model corresponding to the above program, I realized that the nodes are not linked together properly. For example, the getPredicateType() method on a Predicate node returns null. Having read the Xtext user's guide, my impression is that the Xtext default linking semantics should work for my DSL. But, for some reason, the AST nodes of my DSL don't get linked together properly. Can anyone help me in diagnosing this problem?

  • Set Property Value on Master Page from Content Page

    - by Merk
    Hello, I tried following the advice posted here: http://stackoverflow.com/questions/1071920/set-property-value-on-master-page-from-content-page. Specifically the last post about creating a class. However, visual studio keeps giving me an error on my default.aspx.cs page when i try to set the value: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : BasePage { protected override int NavHighlight { get { return new{0} ; } } protected void Page_Load(object sender, EventArgs e) { } } It throws an error on new, the error being: cannot inplicity convert anonymoustype#1 to int Can someone tell me what i might have done wrong here? Here's what my class looks like: using System; using System.Collections.Generic; using System.Linq; using System.Web; /// <summary> /// Summary description for BasePage /// </summary> public abstract class BasePage : System.Web.UI.Page { protected abstract int NavHighlight { get; } protected override void OnLoad(EventArgs e) { base.OnLoad(e); if (this.Master != null) { //value assignment } } public BasePage() { // // TODO: Add constructor logic here // } } Thanks.

  • ways to avoid global temp tables in oracle

    - by Omnipresent
    We just converted our sql server stored procedures to oracle procedures. Sql Server SP's were highly dependent on session tables (INSERT INTO #table1...) these tables got converted as global temporary tables in oracle. We ended up with aroun 500 GTT's for our 400 SP's Now we are finding out that working with GTT's in oracle is considered a last option because of performance and other issues. what other alternatives are there? Collections? Cursors? Our typical use of GTT's is like so: Insert into GTT INSERT INTO some_gtt_1 (column_a, column_b, column_c) (SELECT someA, someB, someC FROM TABLE_A WHERE condition_1 = 'YN756' AND type_cd = 'P' AND TO_NUMBER(TO_CHAR(m_date, 'MM')) = '12' AND (lname LIKE (v_LnameUpper || '%') OR lname LIKE (v_searchLnameLower || '%')) AND (e_flag = 'Y' OR it_flag = 'Y' OR fit_flag = 'Y')); Update the GTT UPDATE some_gtt_1 a SET column_a = (SELECT b.data_a FROM some_table_b b WHERE a.column_b = b.data_b AND a.column_c = 'C') WHERE column_a IS NULL OR column_a = ' '; and later on get the data out of the GTT. These are just sample queries, in actuality the queries are really complext with lot of joins and subqueries. I have a three part question: Can someone show how to transform the above sample queries to collections and/or cursors? Since with GTT's you can work natively with SQL...why go away from the GTTs? are they really that bad. What should be the guidelines on When to use and When to avoid GTT's

  • Is a GWT app running on Google App Engine protected from CSRF

    - by gerdemb
    I'm developing a GWT app running on the Google App Engine and wondering if I need to worry about Cross-site request forgery or is that automatically taken care of for me? For every RPC request that requires authentication, I have the following code: public class BookServiceImpl extends RemoteServiceServlet implements BookService { public void deleteInventory(Key<Inventory> inventoryKey) throws NotLoggedInException, InvalidStateException, NotFoundException { DAO dao = new DAO(); // This will throw NotLoggedInException if user is not logged in User user = dao.getCurrentUser(); // Do deletion here } } public final class DAO extends DAOBase { public User getCurrentUser() throws NotLoggedInException { currentUser = UserServiceFactory.getUserService().getCurrentUser(); if(currentUser == null) { throw new NotLoggedInException(); } return currentUser; } I couldn't find any documentation on how the UserService checks authentication. Is it enough to rely on the code above or do I need to to more? I'm a beginner at this, but from what I understand to avoid CSRF attacks some of the strategies are: adding an authentication token in the request payload instead of just checking a cookie checking the HTTP Referer header I can see that I have cookies set from Google with what look like SID values, but I can't tell from the serialized Java objects in the payloads if tokens are being passed or not. I also don't know if the Referer header is being used or not. So, am I worrying about a non-issue? If not, what is the best strategy here? This is a common enough problem, that there must be standard solutions out there...
