How can I use createquery instead of hibernateTemplate? Thanks in advance!

  • Need help to properly remove duplicates in NHibernate

    - by Michael D. Kirkpatrick
    Here is the problem I am having. I have a database with over 100 records in it. I am paging through the data to get 9 results at a time. When I added a check to see if items are active, it caused the results to start doubling up. A little background: "Product" is the actual product line "ProductSkus" are the actual products that exist in the product line When there is more then 1 ProductSku within Product, it causes a duplicate entry to be returned. See the NHibernate Query below: result = this.Session.CreateCriteria<Model.Product>() .Add(Expression.Eq("IsActive", true)) .AddOrder(new Order("Name", true)) .SetFirstResult(indexNumber).SetMaxResults(maxNumber) // This part of the query duplicates the products .CreateAlias("ProductSkus", "ProdSkus", JoinType.InnerJoin) .Add(Expression.Eq("ProdSkus.IsActive", true)) .CreateAlias("ProductToSubcategory", "ProdToSubcat") .CreateAlias("ProdToSubcat.ProductSubcategory", "ProdSubcat") .Add(Expression.Eq("ProdSubcat.ID", subCatId)) // This part takes out the duplicate products - Removes too many items... // Turns out that with .SetFirstResult(indexNumber).SetMaxResults(maxNumber) // it gets 9 records back then the duplicates are removed. // Example: // Total Records over 100 // Max = 9 // 4 Duplicates removed // Yields 5 records when there should be 9 // Why??? This line is ran in NHibernate on the data after it has been extracted from the SQL server. .SetResultTransformer(new NHibernate.Transform.DistinctRootEntityResultTransformer()) .List<Model.Product>(); I added the DistinctRootEntityResultTransformer to clean up the duplicates. The problem is that it pulls 9 records back that contains duplicates. DistinctRootEntityResultTransformer then cleans up the duplicates in the 9 records. I am basically needing a distinct statement to be ran on the SQL server to begin with. However, distinct on SQL is not going to work since NHibernate by default wants to add every field from every table in the select part of the statement. I am only using the fields that belong to the root table to begin with (Model.Product). If I can tell NHibernate to not add the fields to the joined tables into the select part of the statement along with adding Distinct, it would work. I use NHibernare Profiler to see the actual query: SELECT top 9 this_.ID as ID351_3_, this_.Name as Name351_3_, this_.Description as Descript3_351_3_, this_.IsActive as IsActive351_3_, this_.ManufacturerID as Manufact5_351_3_, prodskus1_.ID as ID373_0_, prodskus1_.Description as Descript2_373_0_, prodskus1_.PartNumber as PartNumber373_0_, prodskus1_.Price as Price373_0_, prodskus1_.IsKit as IsKit373_0_, prodskus1_.IsActive as IsActive373_0_, prodskus1_.IsFeaturedProduct as IsFeatur7_373_0_, prodskus1_.DateAdded as DateAdded373_0_, prodskus1_.Weight as Weight373_0_, prodskus1_.TimesViewed as TimesVi10_373_0_, prodskus1_.TimesOrdered as TimesOr11_373_0_, prodskus1_.ProductID as ProductID373_0_, prodskus1_.OverSizedBoxID as OverSiz13_373_0_, prodtosubc2_.ID as ID362_1_, prodtosubc2_.MasterSubcategory as MasterSu2_362_1_, prodtosubc2_.ProductID as ProductID362_1_, prodtosubc2_.ProductSubcategoryID as ProductS4_362_1_, prodsubcat3_.ID as ID352_2_, prodsubcat3_.Name as Name352_2_, prodsubcat3_.ProductCategoryID as ProductC3_352_2_, prodsubcat3_.ImageID as ImageID352_2_, prodsubcat3_.TriggerShow as TriggerS5_352_2_ FROM Product this_ inner join ProductSku prodskus1_ on this_.ID = prodskus1_.ProductID and (prodskus1_.IsActive = 1) inner join ProductToSubcategory prodtosubc2_ on this_.ID = prodtosubc2_.ProductID inner join ProductSubcategory prodsubcat3_ on prodtosubc2_.ProductSubcategoryID = prodsubcat3_.ID WHERE this_.IsActive = 1 /* @p0 */ and prodskus1_.IsActive = 1 /* @p1 */ and prodsubcat3_.ID = 3 /* @p2 */ ORDER BY this_.Name asc If I hand modify the query and run it directly on the SQL server I get the result set I want (I removed all the extra fields in the select section and added DISTINCT): SELECT DISTINCT top 9 this_.ID as ID351_3_, this_.Name as Name351_3_, this_.Description as Descript3_351_3_, this_.IsActive as IsActive351_3_, this_.ManufacturerID as Manufact5_351_3_, FROM Product this_ inner join ProductSku prodskus1_ on this_.ID = prodskus1_.ProductID and (prodskus1_.IsActive = 1) inner join ProductToSubcategory prodtosubc2_ on this_.ID = prodtosubc2_.ProductID inner join ProductSubcategory prodsubcat3_ on prodtosubc2_.ProductSubcategoryID = prodsubcat3_.ID WHERE this_.IsActive = 1 /* @p0 */ and prodskus1_.IsActive = 1 /* @p1 */ and prodsubcat3_.ID = 3 /* @p2 */ ORDER BY this_.Name asc The big question I now must ask is... What must I change in the NHibernate Query to ultimately get the exact same result? Thanks in advance.

  • MVC multi page form losing session

    - by Bryan
    I have a multi-page form that's used to collect leads. There are multiple versions of the same form that we call campaigns. Some campaigns are 3 page forms, others are 2 pages, some are 1 page. They all share the same lead model and campaign controller, etc. There is 1 action for controlling the flow of the campaigns, and a separate action for submitting all the lead information into the database. I cannot reproduce this locally, and there are checks in place to ensure users can't skip pages. Session mode is InProc. This runs after every POST action which stores the values in session: protected override void OnActionExecuted(ActionExecutedContext filterContext) { base.OnActionExecuted(filterContext); if (this.Request.RequestType == System.Net.WebRequestMethods.Http.Post && this._Lead != null) ParentStore.Lead = this._Lead; } This is the Lead property within the controller: private Lead _Lead; /// <summary> /// Gets the session stored Lead model. /// </summary> /// <value>The Lead model stored in session.</value> protected Lead Lead { get { if (this._Lead == null) this._Lead = ParentStore.Lead; return this._Lead; } } ParentStore class: public static class ParentStore { internal static Lead Lead { get { return SessionStore.Get<Lead>(Constants.Session.Lead, new Lead()); } set { SessionStore.Set(Constants.Session.Lead, value); } } Campaign POST action: [HttpPost] public virtual ActionResult Campaign(Lead lead, string campaign, int page) { if (this.Session.IsNewSession) return RedirectToAction("Campaign", new { campaign = campaign, page = 0 }); if (ModelState.IsValid == false) return View(GetCampaignView(campaign, page), this.Lead); TrackLead(this.Lead, campaign, page, LeadType.Shared); return RedirectToAction("Campaign", new { campaign = campaign, page = ++page }); } The problem is occuring between the above action, and before the following Submit action executes: [HttpPost] public virtual ActionResult Submit(Lead lead, string campaign, int page) { if (this.Session.IsNewSession || this.Lead.Submitted || !this.LeadExists) return RedirectToAction("Campaign", new { campaign = campaign, page = 0 }); lead.AddCustomQuestions(); MergeLead(campaign, lead, this.AdditionalQuestionsType, false); if (ModelState.IsValid == false) return View(GetCampaignView(campaign, page), this.Lead); var sharedLead = this.Lead.ToSharedLead(Request.Form.ToQueryString(false)); //Error occurs here and sends me an email with whatever values are in the form collection. EAUtility.ProcessLeadProxy.SubmitSharedLead(sharedLead); this.Lead.Submitted = true; VisitorTracker.DisplayConfirmationPixel = true; TrackLead(this.Lead, campaign, page, LeadType.Shared); return RedirectToAction(this.ConfirmationView); } Every visitor to our site gets a unique GUID visitorID. But when these error occurs there is a different visitorID between the Campaign POST and the Submit POST. Because we track each form submission via the TrackLead() method during campaign and submit actions I can see session is being lost between calls, despite the OnActionExecuted firing after every POST and storing the form in session. So when there are errors, we get half the form under one visitorID and the remainder of the form under a different visitorID. Luckily we use a third party service which sends an API call every time a form value changes which uses it's own ID. These IDs are consistent between the first half of the form, and the remainder of the form, and the only way I can save the leads from the lost session issues. I should also note that this works fine 99% of the time. EDIT: I've modified my code to explicitly store my lead object in TempData and used the TempData.Keep() method to persist the object between subsequent requests. I've only deployed this behavior to 1 of my 3 sites but so far so good. I had also tried storing my lead objects in Session directly in the controller action i.e., Session.Add("lead", this._Lead); which uses HTTPSessionStateBase, attempting to circumvent the wrapper class, instead of HttpContext.Current.Session which uses HTTPSessionState. This modification made no difference on the issue, as expected.

  • Using my custom colormap in Java for images

    - by John
    Hi everyone! I've got a question concering a colormapping via index. I tried this code found on http://www.podgoretsky.pri.ee/ftp/Docs/Java/Tricks%20of%20the%20Java%20Programming%20Gurus/ch12.htm // Gradient.java // Imports import java.applet.Applet; import java.awt.; import java.awt.image.; public class Gradient extends Applet { final int colors = 32; final int width = 200; final int height = 200; Image img; public void init() { // Create the color map byte[] rbmap = new byte[colors]; byte[] gmap = new byte[colors]; for (int i = 0; i < colors; i++) gmap[i] = (byte)((i * 255) / (colors - 1)); // Create the color model int bits = (int)Math.ceil(Math.log(colors) / Math.log(2)); IndexColorModel model = new IndexColorModel(bits, colors, rbmap, gmap, rbmap); // Create the pixels int pixels[] = new int[width * height]; int index = 0; for (int y = 0; y < height; y++) for (int x = 0; x < width; x++) pixels[index++] = (x * colors) / width; // Create the image img = createImage(new MemoryImageSource(width, height, model, pixels, 0, width)); } public void paint(Graphics g) { g.drawImage(img, 0, 0, this); } } It worked great but I tried to load a custom image jpeg mapped on my own colormap but it didnt work right. I saw only a bunch of green and blue pixels drawn on a white background. My custom color map method here: public void inintByteArrays() { double[][] c = // basic color map { { 0.0000, 0.0000, 0.5625 }, { 0.0000, 0.0000, 0.6250 }, { 0.0000, 0.0000, 0.6875 }, { 0.0000, 0.0000, 0.6875 }, { 0.0000, 0.0000, 0.7500 }, { 0.0000, 0.0000, 0.8125 }, { 0.0000, 0.0000, 0.8750 }, { 0.0000, 0.0000, 0.9375 }, { 0.0000, 0.0000, 1.0000 }, { 0.0000, 0.0625, 1.0000 }, { 0.0000, 0.1250, 1.0000 }, { 0.0000, 0.1875, 1.0000 }, { 0.0000, 0.2500, 1.0000 }, { 0.0000, 0.3125, 1.0000 }, { 0.0000, 0.3750, 1.0000 }, { 0.0000, 0.4375, 1.0000 }, { 0.0000, 0.5000, 1.0000 }, { 0.0000, 0.5625, 1.0000 }, { 0.0000, 0.6250, 1.0000 }, { 0.0000, 0.6875, 1.0000 }, { 0.0000, 0.7500, 1.0000 }, { 0.0000, 0.8125, 1.0000 }, { 0.0000, 0.8750, 1.0000 }, { 0.0000, 0.9375, 1.0000 }, { 0.0000, 1.0000, 1.0000 }, { 0.0625, 1.0000, 0.9375 }, { 0.1250, 1.0000, 0.8750 }, { 0.1875, 1.0000, 0.8125 }, { 0.2500, 1.0000, 0.7500 }, { 0.3125, 1.0000, 0.6875 }, { 0.3750, 1.0000, 0.6250 }, { 0.4375, 1.0000, 0.5625 }, { 0.5000, 1.0000, 0.5000 }, { 0.5625, 1.0000, 0.4375 }, { 0.6250, 1.0000, 0.3750 }, { 0.6875, 1.0000, 0.3125 }, { 0.7500, 1.0000, 0.2500 }, { 0.8125, 1.0000, 0.1875 }, { 0.8750, 1.0000, 0.1250 }, { 0.9375, 1.0000, 0.0625 }, { 1.0000, 1.0000, 0.0000 }, { 1.0000, 0.9375, 0.0000 }, { 1.0000, 0.8750, 0.0000 }, { 1.0000, 0.8125, 0.0000 }, { 1.0000, 0.7500, 0.0000 }, { 1.0000, 0.6875, 0.0000 }, { 1.0000, 0.6250, 0.0000 }, { 1.0000, 0.5625, 0.0000 }, { 1.0000, 0.5000, 0.0000 }, { 1.0000, 0.4375, 0.0000 }, { 1.0000, 0.3750, 0.0000 }, { 1.0000, 0.3125, 0.0000 }, { 1.0000, 0.2500, 0.0000 }, { 1.0000, 0.1875, 0.0000 }, { 1.0000, 0.1250, 0.0000 }, { 1.0000, 0.0625, 0.0000 }, { 1.0000, 0.0000, 0.0000 }, { 0.9375, 0.0000, 0.0000 }, { 0.8750, 0.0000, 0.0000 }, { 0.8125, 0.0000, 0.0000 }, { 0.7500, 0.0000, 0.0000 }, { 0.6875, 0.0000, 0.0000 }, { 0.6250, 0.0000, 0.0000 }, { 0.5625, 0.0000, 0.0000 }, { 0.5000, 0.0000, 0.0000 } }; for (int i = 0; i < c.length; i++) { for (int j = 0; j < c[i].length; j++) { if (j == 0) r[i] = (byte) ((byte) c[i][j]*255); if (j == 1) g[i] = (byte) ((byte) c[i][j]*255); if (j == 2) b[i] = (byte) ((byte) c[i][j]*255); } } My question is how I can use my colormap for any image I want to load and map in the right way.

  • Many to many self join through junction table

    - by Peter
    I have an EF model that can self-reference through an intermediary class to define a parent/child relationship. I know how to do a pure many-to-many relationship using the Map command, but for some reason going through this intermediary class is causing problems with my mappings. The intermediary class provides additional properties for the relationship. See the classes, modelBinder logic and error below: public class Equipment { [Key] public int EquipmentId { get; set; } public virtual List<ChildRecord> Parents { get; set; } public virtual List<ChildRecord> Children { get; set; } } public class ChildRecord { [Key] public int ChildId { get; set; } [Required] public int Quantity { get; set; } [Required] public Equipment Parent { get; set; } [Required] public Equipment Child { get; set; } } I've tried building the mappings in both directions, though I only keep one set in at a time: modelBuilder.Entity<ChildRecord>() .HasRequired(x => x.Parent) .WithMany(x => x.Children ) .WillCascadeOnDelete(false); modelBuilder.Entity<ChildRecord>() .HasRequired(x => x.Child) .WithMany(x => x.Parents) .WillCascadeOnDelete(false); OR modelBuilder.Entity<Equipment>() .HasMany(x => x.Parents) .WithRequired(x => x.Child) .WillCascadeOnDelete(false); modelBuilder.Entity<Equipment>() .HasMany(x => x.Children) .WithRequired(x => x.Parent) .WillCascadeOnDelete(false); Regardless of which set I use, I get the error: The foreign key component 'Child' is not a declared property on type 'ChildRecord'. Verify that it has not been explicitly excluded from the model and that it is a valid primitive property. when I try do deploy my ef model to the database. If I build it without the modelBinder logic in place then I get two ID columns for Child and two ID columns for Parent in my ChildRecord table. This makes sense since it tries to auto create the navigation properties from Equipment and doesn't know that there are already properties in ChildRecord to fulfill this need. I tried using Data Annotations on the class, and no modelBuilder code, this failed with the same error as above: [Required] [ForeignKey("EquipmentId")] public Equipment Parent { get; set; } [Required] [ForeignKey("EquipmentId")] public Equipment Child { get; set; } AND [InverseProperty("Child")] public virtual List<ChildRecord> Parents { get; set; } [InverseProperty("Parent")] public virtual List<ChildRecord> Children { get; set; } I've looked at various other answers around the internet/SO, and the common difference seems to be that I am self joining where as all the answers I can find are for two different types.

  • Setup database for Unit tests with Spring, Hibernate and Spring Transaction Support

    - by Michael Bulla
    I want to test integration of dao-layer with my service-layer in a unit-test. So I need to setup some data in my database (hsql). For this setup I need an own transaction at the begining of my testcase to ensure that all my setup is really commited to database before starting my testcase.

  • TypeError: Object {...} has no method 'find' - when using mongoose with express

    - by sdouble
    I'm having trouble getting data from MongoDB using mongoose schemas with express. I first tested with just mongoose in a single file (mongoosetest.js) and it works fine. But when I start dividing it all up with express routes and config files, things start to break. I'm sure it's something simple, but I've spent the last 3 hours googling and trying to figure out what I'm doing wrong and can't find anything that matches my process enough to compare. mongoosetest.js (this works fine, but not for my application) var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/meanstack'); var db = mongoose.connection; var userSchema = mongoose.Schema({ name: String }, {collection: 'users'}); var User = mongoose.model('User', userSchema); User.find(function(err, users) { console.log(users); }); These files are where I'm having issues. I'm sure it's something silly, probably a direct result of using external files, exports, and requires. My server.js file just starts up and configures express. I also have a routing file and a db config file. routing file (allRoutes.js) var express = require('express'); var router = express.Router(); var db = require('../config/db'); var User = db.User(); // routes router.get('/user/list', function(req, res) { User.find(function(err, users) { console.log(users); }); }); // catch-all route router.get('*', function(req, res) { res.sendfile('./public/index.html'); }); module.exports = router; dbconfig file (db.js) var mongoose = require('mongoose'); var dbHost = 'localhost'; var dbName = 'meanstack'; var db = mongoose.createConnection(dbHost, dbName); var Schema = mongoose.Schema, ObjectId = Schema.ObjectId; db.once('open', function callback() { console.log('connected'); }); // schemas var User = new Schema({ name : String }, {collection: 'users'}); // models mongoose.model('User', User); var User = mongoose.model('User'); //exports module.exports.User = User; I receive the following error when I browse to localhost:3000/user/list TypeError: Object { _id: 5398bed35473f98c494168a3 } has no method 'find' at Object.module.exports [as handle] (C:\...\routes\allRoutes.js:8:8) at next_layer (C:\...\node_modules\express\lib\router\route.js:103:13) at Route.dispatch (C:\...\node_modules\express\lib\router\route.js:107:5) at C:\...\node_modules\express\lib\router\index.js:213:24 at Function.proto.process_params (C:\...\node_modules\express\lib\router\index.js:284:12) at next (C:\...\node_modules\express\lib\router\index.js:207:19) at Function.proto.handle (C:\...\node_modules\express\lib\router\index.js:154:3) at Layer.router (C:\...\node_modules\express\lib\router\index.js:24:12) at trim_prefix (C:\...\node_modules\express\lib\router\index.js:255:15) at C:\...\node_modules\express\lib\router\index.js:216:9 Like I said, it's probably something silly that I'm messing up with trying to organize my code since my single file (mongoosetest.js) works as expected.

  • Categorized Document Management System

    - by cmptrgeekken
    At the company I work for, we have an intranet that provides employees with access to a wide variety of documents. These documents fall into several categories and subcategories, and each of these categories have their own web page. Below is one such page (each of the links shown will link to a similar view for that category): We currently store each document as a file on the web server and hand-code links to these documents whenever we need to add a new document. This is tedious and error-prone, and it also means we lack any sort of security for accessing these documents. I began looking into document management systems (like KnowledgeTree and OpenKM), however, none of these systems seem to provide a categorized view like in the preview above. My question is ... does anyone know of any Document Management System that allow for the type of flexibility we currently have with hand-coding links to our documents into various webpages (major and minor , while also providing security, ease of use, and (less important) version control? Or do you think I'd be better off developing such a system from scratch?

  • An offscreen MKMapView behaves differently in 3.2, 4.0

    - by Duane Fields
    In 3.1 I've been using an "offscreen" MKMapView to create map images that I can rotate, crop and so forth before presenting them the user. In 3.2 and 4.0 this technique no longer works quite right. Here's some code that illustrates the problem, followed by my theory. // create map view _mapView = [[MKMapView alloc] initWithFrame:CGRectMake(0, 0, MAP_FRAME_SIZE, MAP_FRAME_SIZE)]; _mapView.zoomEnabled = NO; _mapView.scrollEnabled = NO; _mapView.delegate = self; _mapView.mapType = MKMapTypeSatellite; // zoom in to something enough to fill the screen MKCoordinateRegion region; CLLocationCoordinate2D center = {30.267222, -97.763889}; region.center = center; MKCoordinateSpan span = {0.1, 0.1 }; region.span = span; _mapView.region = region; // set scrollview content size to full the imageView _scrollView.contentSize = _imageView.frame.size; // force it to load #ifndef __IPHONE_3_2 // in 3.1 we can render to an offscreen context to force a load UIGraphicsBeginImageContext(_mapView.frame.size); [_mapView.layer renderInContext:UIGraphicsGetCurrentContext()]; UIGraphicsEndImageContext(); #else // in 3.2 and above, the renderInContext trick doesn't work... // this at least causes the map to render, but it's clipped to what appears to be // the viewPort size, plus some padding [self.view addSubview:_mapView]; #endif when the map is done loading, I snap picture of it and stuff it in my scrollview - (void)mapViewDidFinishLoadingMap:(MKMapView *)mapView { NSLog(@"[MapBuilder] mapViewDidFinishLoadingMap"); // render the map to a UIImage UIGraphicsBeginImageContext(mapView.bounds.size); // the first sub layer is just the map, the second is the google layer, this sublayer structure might change of course [[[mapView.layer sublayers] objectAtIndex:0] renderInContext:UIGraphicsGetCurrentContext()]; // we are done with the mapView at this point, we need its ram! _mapView.delegate = nil; [_mapView release]; [_mapView removeFromSuperview]; _mapView = nil; UIImage* mapImage = [UIGraphicsGetImageFromCurrentImageContext() retain]; UIGraphicsEndImageContext(); _imageView.image = mapImage; [mapImage release], mapImage = nil; } The first problem is that in 3.1 rendering to a context would trigger the map to begin loading. This no longer works in 3.2, 4.0. The only thing I have found would trigger the load is to temporarily add the map to the view (i.e. make it visible). The problem being that the map only renders to the visible area of the screen, plus a little padding. The frame/bounds are fine, but it appears to be "helpfully" optimizes the loading to limit the tiles to those visible on the screen or close to it. Any ideas how to force the map to load at full size? Anyone else have this issue?

  • There is no ViewData item of type 'IEnumerable<SelectListItem>' that has the key 'xxx'.

    - by Jimbo
    There are a couple of posts about this on Stack Overflow but none with an answer that seem to fix the problem in my current situation. I have a page with a table in it, each row has a number of text fields and a dropdown. All the dropdowns need to use the same SelectList data so I have set it up as follows: Controller ViewData["Submarkets"] = new SelectList(submarketRep.AllOrdered(), "id", "name"); View <%= Html.DropDownList("submarket_0", (SelectList)ViewData["Submarkets"], "(none)") %> I have used exactly this setup in many places, but for some reason in this particular view I get the error: There is no ViewData item of type 'IEnumerable' that has the key 'submarket_0'.

  • Silverlight 4 WCF RIA Services and MVVM is not as simple

    - by Thomas Jaskula
    [Disclaimer: I'm ASP.NET MVC Developer] Hi, I'm looking for some best practices with implementing MVVM pattern with WCF RIA in Silverlight 4. I'm not looking to use MEF of IoC for locating my ViewModels. What I would like to know is how to apply MVVM pattern with Silverlight 4 and WCF RIA. I don't want to use other stuff like Prism or MVVM Light toolkit. I found many examples on Internet showing how it is wonderful to drag and drop a datasource on the view and the job is done (it reminds me about my first VB6 developments). I tried to implement MVVM with WCF RIA and it's not strightforward at all. If I understand, the MVVM should contain all the logic in order to unit test it in isolation but when it comes to combine it with WCF RIA it's another story. I have the following questions. Can I use a generated metadata as model ? It would be easier to use it that if I write all from the scratch. As I saw the only way I could get data is through DomainContext or through direct binding in the view (local ressource). I don't want the direct binding in the view, not testable at all. On the other hand I can't use DomainContext, it doesn't expose any single entity !!! All I have is the EntitySet that I can bind to datagrid. How do I bind a single Entity to the DataForm from the ViewModel ? How do I udpate the model to the database ? How do I navigate from one Entity to a collection of it's itemps. For example if I have a Company Entity I would like to show a DataFrom to update a entite informations and a datagrid to show companies adresses. When saving a form would like to save information to Company and for example an information avout which adress was selected as active. Please help me understand how to do it well. Or maybe I should drop the WCF RIA and to do it with WCF from scratch ? What do you think ?

  • android listview set dynamically background color of views

    Hi everybody, I know that there have quite a lot of answers to similar questions but I couldn't find any solution to my question, so new topic : I'm creating a listview, with one basic view per row, my try is to change the background color of the view by .setbackgroundcolor, but nothing's doing the trick... I define an array of color at the beginning of my resources and i'm trying to display it, I also tried to put the array in the class, write the color like #00FF00, int, and I wanted to try 0x...... but as my colors are in an array, I can't do 0x+myColorsArray[i] because Eclipse tells me that it's not a proper hex color... I'm getting a bit desperate... thanks for any help

  • Maintain cookie session in Android

    - by datguywhowanders
    Okay, I have an android application that has a form in it, two EditText, a spinner, and a login button. The user selects the service from the spinner, types in their user name and password, and clicks login. The data is sent via POST, a response is returned, it's handled, a new webview is launched, the html string generated form the response is loaded, and I have the home page of whatever service the user selected. That's all well and good. Now, when the user clicks on a link, the login info can't be found, and the page asks the user to login again. My login session is being dropped somewhere, and I'm not certain how to pass the info from the class that controls the main part of my app to the class that just launches the webview activity. The on click handler from the form login button: private class FormOnClickListener implements View.OnClickListener { public void onClick(View v) { String actionURL, user, pwd, user_field, pwd_field; actionURL = "thePageURL"; user_field = "username"; //this changes based on selections in a spinner pwd_field = "password"; //this changes based on selections in a spinner user = "theUserLogin"; pwd = "theUserPassword"; List<NameValuePair> myList = new ArrayList<NameValuePair>(); myList.add(new BasicNameValuePair(user_field, user)); myList.add(new BasicNameValuePair(pwd_field, pwd)); HttpParams params = new BasicHttpParams(); DefaultHttpClient client = new DefaultHttpClient(params); HttpPost post = new HttpPost(actionURL); HttpResponse response = null; BasicResponseHandler myHandler = new BasicResponseHandler(); String endResult = null; try { post.setEntity(new UrlEncodedFormEntity(myList)); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } try { response = client.execute(post); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } try { endResult = myHandler.handleResponse(response); } catch (HttpResponseException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } List cookies = client.getCookieStore().getCookies(); if (!cookies.isEmpty()) { for (int i = 0; i < cookies.size(); i++) { cookie = cookies.get(i); } } Intent myWebViewIntent = new Intent(MsidePortal.this, MyWebView.class); myWebViewIntent.putExtra("htmlString", endResult); myWebViewIntent.putExtra("actionURL", actionURL); startActivity(myWebViewIntent); } } And here is the webview class that handles the response display: public class MyWebView extends android.app.Activity{ private class MyWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { view.loadUrl(url); return true; } } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.web); MyWebViewClient myClient = new MyWebViewClient(); WebView webview = (WebView)findViewById(R.id.mainwebview); webview.getSettings().setBuiltInZoomControls(true); webview.getSettings().setJavaScriptEnabled(true); webview.setWebViewClient(myClient); Bundle extras = getIntent().getExtras(); if(extras != null) { // Get endResult String htmlString = extras.getString("htmlString"); String actionURL = extras.getString("actionURL"); Cookie sessionCookie = MsidePortal.cookie; CookieSyncManager.createInstance(this); CookieManager cookieManager = CookieManager.getInstance(); if (sessionCookie != null) { cookieManager.removeSessionCookie(); String cookieString = sessionCookie.getName() + "=" + sessionCookie.getValue() + "; domain=" + sessionCookie.getDomain(); cookieManager.setCookie(actionURL, cookieString); CookieSyncManager.getInstance().sync(); } webview.loadDataWithBaseURL(actionURL, htmlString, "text/html", "utf-8", actionURL); } } } I've had mixed success implementing that cookie solution. It seems to work for one service I log into that I know keeps the cookies on the server (old, archaic, but it works and they don't want to change it.) The service I'm attempting now requires the user to keep cookies on their local machine, and it does not work with this setup. Any suggestions?

  • Making a ViewFlipper like the Home Screen using MotionEvent.ACTION_MOVE

    - by DJTripleThreat
    Ok I have a ViewFlipper with three LinearLayouts nested inside it. It defaults to showing the first one. This code: // Assumptions in my Activity class: // oldTouchValue is a float // vf is my view flipper @Override public boolean onTouchEvent(MotionEvent touchEvent) { switch (touchEvent.getAction()) { case MotionEvent.ACTION_DOWN: { oldTouchValue = touchEvent.getX(); break; } case MotionEvent.ACTION_UP: { float currentX = touchEvent.getX(); if (oldTouchValue < currentX) { vf.setInAnimation(AnimationHelper.inFromLeftAnimation()); vf.setOutAnimation(AnimationHelper.outToRightAnimation()); vf.showNext(); } if (oldTouchValue > currentX) { vf.setInAnimation(AnimationHelper.inFromRightAnimation()); vf.setOutAnimation(AnimationHelper.outToLeftAnimation()); vf.showPrevious(); } break; } case MotionEvent.ACTION_MOVE: { // TODO: Some code to make the ViewFlipper // act like the home screen. break; } } return false; } public static class AnimationHelper { public static Animation inFromRightAnimation() { Animation inFromRight = new TranslateAnimation( Animation.RELATIVE_TO_PARENT, +1.0f, Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f); inFromRight.setDuration(350); inFromRight.setInterpolator(new AccelerateInterpolator()); return inFromRight; } public static Animation outToLeftAnimation() { Animation outtoLeft = new TranslateAnimation( Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, -1.0f, Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f); outtoLeft.setDuration(350); outtoLeft.setInterpolator(new AccelerateInterpolator()); return outtoLeft; } // for the next movement public static Animation inFromLeftAnimation() { Animation inFromLeft = new TranslateAnimation( Animation.RELATIVE_TO_PARENT, -1.0f, Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f); inFromLeft.setDuration(350); inFromLeft.setInterpolator(new AccelerateInterpolator()); return inFromLeft; } public static Animation outToRightAnimation() { Animation outtoRight = new TranslateAnimation( Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, +1.0f, Animation.RELATIVE_TO_PARENT, 0.0f, Animation.RELATIVE_TO_PARENT, 0.0f); outtoRight.setDuration(350); outtoRight.setInterpolator(new AccelerateInterpolator()); return outtoRight; } } ... handles the view flipping but the animations are very "on/off". I'm wondering if someone can help me out with the last part. Assuming that I can access the LinearLayouts, is there a way where I can set the position of the layouts based on deltaX and deltaY? Someone gave me this link: https://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob;f=core/java/android/view/animation/TranslateAnimation.java;h=d2ff754ac327dda0fe35e610752abb78904fbb66;hb=HEAD and said I should refer to the applyTransformation method for hints on how to do this but I don't know how to repeat this same behavior.

    I'm trying to use F# for an ASP.NET MVC application. One my controller actions sends an F# list to the view, so I write: <%@ Page Language="C#" Inherits="ViewPage<FSharpList<int>>" %> Of course, for this to work, I have to add Microsoft.FSharp.Collections to the namespaces element in my web.config: <add namespace="Microsoft.FSharp.Collections"/> and add a reference to FSharp.Core, in the assemblies element: <add assembly="FSharp.Core, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/> As soon as I add this assembly reference, every view (whether it uses an F# type or not) fails with this error: error FS1221: FSharp.Core.sigdata not found alongside FSharp.Core I can work around this by not having any F# specific types in my views, but what's the reason for this error? Also, where's FSharp.Core.sigdata ? It's not in my GAC and I can't find it anywhere.

  • TTThumbsViewController + navigationController issue

    - by michael
    Hi, .. 2 questions. I am only using Three20 for a gallery in my app. When I push my .. : TTThumbsViewController from another view, the navigation bar is not the color I want it to be (as per the rest of my app). I have set up a TTDefaultStyleSheet as per this stackoverflow QA. Is there something special I have to do as I am only using the TTThumbsViewController? The thumbs view is also created with extra space at the top, as though it is leaving room for a navigation controller, without knowing that one is already there. How can I tell the TTThumbsViewController to use the existing uinavigationcontroller? Or behave as though it is? MYThumbsViewController *mYThumbsViewController = [MYThumbsViewController alloc]; [self.navigationController pushViewController:mYThumbsViewController animated:YES]; The problem depicted graphically: Thanks!

  • iPhone Curl Left and Curl Right transitions

    - by Dimitris
    I am looking for a way to do a UIViewAnimationTransitionCurlUp or UIViewAnimationTransitionCurlDown transition on the iPhone but instead of top to bottom, do it from the left to right (or top/bottom in landscape mode). I've seen this asked aroud the internet a few times but none sems to get an answer. However I feel this is doable. I have tried changing the View's transform and the view.layer's transform but that didn't affect the transition. Since the transition changes when the device changes orientation I presume there is a way to fool the device to use the landscape transition in portrait mode and vice versa?
