• Android -- autoLink

  - by Ryan

  Is there any way to Linkify a specific TextView that is contained within a ListView? I tried using android:autoLink="all" but that didn't work. I was getting an out of context error. Important also to note: the ListView is my second view in the ViewFlipper. I have also tried: View mItemView = mAdapter.getView(2, null, null); TextView infoText = (TextView) mItemView.findViewById(R.id.rowText2); Linkify.addLinks(infoText, Linkify.ALL); Right after the adapter was bound to the ListView and the View was switched. No luck. Here is the stack trace: 06-03 21:19:25.180: ERROR/AndroidRuntime(1214): Uncaught handler: thread main exiting due to uncaught exception 06-03 21:19:25.219: ERROR/AndroidRuntime(1214): android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag.

• UINavigationBar unresponsive after canceling a UITableView search in nav controller in tab bar in a popover

  - by Mark

  Ok, this is an odd one and I can reproduce it with a new project easily. Here is the setup: I have a UISplitViewController. In the left side I have a UITabBarController. In this tab bar controller I have two UINavigationControllers. In the navigation controllers I have UITableViewControllers. These table views have search bars on them. Ok, what happens with this setup is that if I'm in portrait mode and bring up this view in the popover and I start a search in one of the table views and cancel it, the navigation bar becomes unresponsive. That is, the "back" button as well as the right side button cannot be clicked. If I do the exact same thing in landscape mode so we are not in a popover, this doesn't happen. The navigation bar stays responsive. So, the problem only seems to happen inside a popover. I've also noticed that if I do the search but click on an item in the search results which ends up loading something into the "detail view" of the split view and dismissing the popover, and then come back to the popover and then click the Cancel button for the search, the navigation bar is responsive. My application is a universal app and uses the same tab bar controller in the iPhone interface and it works there without this issue. As I mentioned above, I can easily reproduce this with a new project. Here are the steps if you want to try it out yourself: start new project - split view create new UITableViewController class (i named TableViewController) uncomment out the viewDidLoad method as well as the rightBarButtonItem line in viewDidLoad (so we will have an Edit button in the navigation bar) enter any values you want to return from numberOfSectioinsInTableView and numberOfRowsInSection methods open MainWindow.xib and do the following: please note that you will need to be viewing the xib in the middle "view mode" so you can expand the contents of the items drag a Tab Bar Controller into the xib to replace the Navigation Controller item drag a Navigation Controller into the xib as another item under the Tab Bar Controller delete the other two view controllers that are under the Tab Bar Controller (so, now our tab bar has just the one navigation controller on it) inside the navigation controller, drag in a Table View Controller and use it to replace the View Controller (Root View Controller) change the class of the new Table View Controller to the class created above (TableViewController for me) double-click on the Table View under the new Table View Controller to open it up (will be displayed in the tab bar inside the split view controller) drag a "Search Bar and Search Display" onto the table view save the xib run the project in simulator while in portrait mode, click on the Root List button to bring up popover notice the Edit button is clickable click in the Search box - we go into search mode click the Cancel button to exit search mode notice the Edit button no longer works So, can anyone help me figure out why this is happening? Thanks, Mark

• Are there scenarios where the ViewModel needs to invoke methods on the View w.r.t. MVVM in WPF?

  - by Gishu

  As per the pattern, the ViewModel exposes Properties(with change notification) and Commands (to notify the VM of user actions) that the View binds to. The only communication that flows from the VM to the View is the property change notifications (so that the View can refresh itself with updated data). In MVP or PresentationModel form of the pattern (if I'm not mistaken), the View implements a plain vanilla interface (consisting of methods, properties and/or events). With MVVM, it feels methods on the IView have been outlawed (along with IView itself). One scenario I could think of was to set the focus to a certain control in the View. (When the user does ActionX, the focus should immediately be set to FieldY). In MVP, I'd write this as IView.ActivateField(NameConstant), which the presenter or PM would invoke. In MVVM, this seems to be a fringe case that needs a workaround / little bit of code-behind. The VM implements an ActiveField Property, which it sets to NameConstant. The view picks up the change notification event and in a code-behind event handler, activates the Name control. Is the above just an exception to the norm? Or are there other such scenarios, where the VM needs to invoke a method on the View ?

• How do compare dates when one of those are in string format in android

  I am very much new to android so need some good help with a code example. I am getting a date in form of string from a server in the following format 2012-08-17 00:00:00 I want to compare this string with current date to find the difference between the dates in the form of year, months and days...

• How can I draw a shadow beyond a UIView's bounds?

  - by Christian

  I'm using the method described at http://stackoverflow.com/questions/805872/how-do-i-draw-a-shadow-under-a-uiview to draw shadow behind a view's content. The shadow is clipped to the view's bounds, although I disabled "Clip Subviews" in Interface Builder for the view. Is it possible to draw a shadow around a view and not only in a view? I don't want to draw the shadow inside the view because the view would receive touch events for the shadow area, which really belongs to the background.

• Workarounds for supporting MVVM in the Silverlight TreeView Control

  - by cibrax

  MVVM (Model-View-ViewModel) is the pattern that you will typically choose for building testable user interfaces either in WPF or Silverlight. This pattern basically relies on the data binding support in those two technologies for mapping an existing model class (the view model) to the different parts of the UI or view. Unfortunately, MVVM was not threated as first citizen for some of controls released out of the box in the Silverlight runtime or the Silverlight toolkit. That means that using data binding for implementing MVVM is not always something trivial and usually requires some customization in the existing controls. In ran into different problems myself trying to fully support data binding in controls like the tree view or the context menu or things like drag & drop.  For that reason, I decided to write this post to show how the tree view control or the tree view items can be customized to support data binding in many of its properties. In first place, you will typically use a tree view for showing hierarchical data so the view model somehow must reflect that hierarchy. An easy way to implement hierarchy in a model is to use a base item element like this one, public abstract class TreeItemModel { public abstract IEnumerable<TreeItemModel> Children; } You can later derive your concrete model classes from that base class. For example, public class CustomerModel { public string FullName { get; set; } public string Address { get; set; } public IEnumerable<OrderModel> Orders { get; set; } }   public class CustomerTreeItemModel : TreeItemModel { public CustomerTreeItemModel(CustomerModel customer) { }   public override IEnumerable<TreeItemModel> Children { get { // Return orders } } } The Children property in the CustomerTreeItem model implementation can return for instance an ObservableCollection<TreeItemModel> with the orders, so the tree view will automatically subscribe to all the changes in the collection. You can bind this model to the tree view control in the UI by using a Hierarchical data template. <e:TreeView x:Name="TreeView" ItemsSource="{Binding Customers}"> <e:TreeView.ItemTemplate> <sdk:HierarchicalDataTemplate ItemsSource="{Binding Children}"> <!-- TEMPLATE --> </sdk:HierarchicalDataTemplate> </e:TreeView.ItemTemplate> </e:TreeView> An interesting behavior with the Children property and the Hierarchical data template is that the Children property is only invoked before the expansion, so you can use lazy load at this point (The tree view control will not expand the whole tree in the first expansion). The problem with using MVVM in this control is that you can not bind properties in model with specific properties of the TreeView item such as IsSelected or IsExpanded. Here is where you need to customize the existing tree view control to support data binding in tree items. public class CustomTreeView : TreeView { public CustomTreeView() { }   protected override DependencyObject GetContainerForItemOverride() { CustomTreeViewItem tvi = new CustomTreeViewItem(); Binding expandedBinding = new Binding("IsExpanded"); expandedBinding.Mode = BindingMode.TwoWay; tvi.SetBinding(CustomTreeViewItem.IsExpandedProperty, expandedBinding); Binding selectedBinding = new Binding("IsSelected"); selectedBinding.Mode = BindingMode.TwoWay; tvi.SetBinding(CustomTreeViewItem.IsSelectedProperty, selectedBinding); return tvi; } }   public class CustomTreeViewItem : TreeViewItem { public CustomTreeViewItem() { }   protected override DependencyObject GetContainerForItemOverride() { CustomTreeViewItem tvi = new CustomTreeViewItem(); Binding expandedBinding = new Binding("IsExpanded"); expandedBinding.Mode = BindingMode.TwoWay; tvi.SetBinding(CustomTreeViewItem.IsExpandedProperty, expandedBinding); Binding selectedBinding = new Binding("IsSelected"); selectedBinding.Mode = BindingMode.TwoWay; tvi.SetBinding(CustomTreeViewItem.IsSelectedProperty, selectedBinding); return tvi; } } You basically need to derive the TreeView and TreeViewItem controls to manually add a binding for the properties you need. In the example above, I am adding a binding for the “IsExpanded” and “IsSelected” properties in the items. The model for the tree items now needs to be extended to support those properties as well, public abstract class TreeItemModel : INotifyPropertyChanged { bool isExpanded = false; bool isSelected = false;   public abstract IEnumerable<TreeItemModel> Children { get; }   public bool IsExpanded { get { return isExpanded; } set { isExpanded = value; if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("IsExpanded")); } }   public bool IsSelected { get { return isSelected; } set { isSelected = value; if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("IsSelected")); } }   public event PropertyChangedEventHandler PropertyChanged; } However, as soon as you use this custom tree view control, you lose all the automatic styles from the built-in toolkit themes because they are tied to the control type (TreeView in this case).  The only ugly workaround I found so far for this problem is to copy the styles from the Toolkit source code and reuse them in the application.

• how to define a field of view for the entire map for shadow?

  - by Mehdi Bugnard

  I recently added "Shadow Mapping" in my XNA games to include shadows. I followed the nice and famous tutorial from "Riemers" : http://www.riemers.net/eng/Tutorials/XNA/Csharp/Series3/Shadow_map.php . This code work nice and I can see my source of light and shadow. But the problem is that my light source does not match the field of view that I created. I want the light covers the entire map of my game. I don't know why , but the light only affect 2-3 cubes of my map. ScreenShot: (the emission of light illuminates only 2-3 blocks and not the full map) Here is my code i create the fieldOfView for LightviewProjection Matrix: Vector3 lightDir = new Vector3(10, 52, 10); lightPos = new Vector3(10, 52, 10); Matrix lightsView = Matrix.CreateLookAt(lightPos, new Vector3(105, 50, 105), new Vector3(0, 1, 0)); Matrix lightsProjection = Matrix.CreatePerspectiveFieldOfView(MathHelper.PiOver2, 1f, 20f, 1000f); lightsViewProjectionMatrix = lightsView * lightsProjection; As you can see , my nearPlane and FarPlane are set to 20f and 100f . So i don't know why the light stop after 2 cubes. it's should be bigger Here is set the value to my custom effect HLSL in the shader file /* SHADOW VALUE */ effectWorld.Parameters["LightDirection"].SetValue(lightDir); effectWorld.Parameters["xLightsWorldViewProjection"].SetValue(Matrix.Identity * .lightsViewProjectionMatrix); effectWorld.Parameters["xWorldViewProjection"].SetValue(Matrix.Identity * arcadia.camera.View * arcadia.camera.Projection); effectWorld.Parameters["xLightPower"].SetValue(1f); effectWorld.Parameters["xAmbient"].SetValue(0.3f); Here is my custom HLSL shader effect file "*.fx" // This sample uses a simple Lambert lighting model. float3 LightDirection = normalize(float3(-1, -1, -1)); float3 DiffuseLight = 1.25; float3 AmbientLight = 0.25; uniform const float3 DiffuseColor = 1; uniform const float Alpha = 1; uniform const float3 EmissiveColor = 0; uniform const float3 SpecularColor = 1; uniform const float SpecularPower = 16; uniform const float3 EyePosition; // FOG attribut uniform const float FogEnabled ; uniform const float FogStart ; uniform const float FogEnd ; uniform const float3 FogColor ; float3 cameraPos : CAMERAPOS; texture Texture; sampler Sampler = sampler_state { Texture = (Texture); magfilter = LINEAR; minfilter = LINEAR; mipfilter = LINEAR; AddressU = mirror; AddressV = mirror; }; texture xShadowMap; sampler ShadowMapSampler = sampler_state { Texture = <xShadowMap>; magfilter = LINEAR; minfilter = LINEAR; mipfilter = LINEAR; AddressU = clamp; AddressV = clamp; }; /* *************** */ /* SHADOW MAP CODE */ /* *************** */ struct SMapVertexToPixel { float4 Position : POSITION; float4 Position2D : TEXCOORD0; }; struct SMapPixelToFrame { float4 Color : COLOR0; }; struct SSceneVertexToPixel { float4 Position : POSITION; float4 Pos2DAsSeenByLight : TEXCOORD0; float2 TexCoords : TEXCOORD1; float3 Normal : TEXCOORD2; float4 Position3D : TEXCOORD3; }; struct SScenePixelToFrame { float4 Color : COLOR0; }; float DotProduct(float3 lightPos, float3 pos3D, float3 normal) { float3 lightDir = normalize(pos3D - lightPos); return dot(-lightDir, normal); } SSceneVertexToPixel ShadowedSceneVertexShader(float4 inPos : POSITION, float2 inTexCoords : TEXCOORD0, float3 inNormal : NORMAL) { SSceneVertexToPixel Output = (SSceneVertexToPixel)0; Output.Position = mul(inPos, xWorldViewProjection); Output.Pos2DAsSeenByLight = mul(inPos, xLightsWorldViewProjection); Output.Normal = normalize(mul(inNormal, (float3x3)World)); Output.Position3D = mul(inPos, World); Output.TexCoords = inTexCoords; return Output; } SScenePixelToFrame ShadowedScenePixelShader(SSceneVertexToPixel PSIn) { SScenePixelToFrame Output = (SScenePixelToFrame)0; float2 ProjectedTexCoords; ProjectedTexCoords[0] = PSIn.Pos2DAsSeenByLight.x / PSIn.Pos2DAsSeenByLight.w / 2.0f + 0.5f; ProjectedTexCoords[1] = -PSIn.Pos2DAsSeenByLight.y / PSIn.Pos2DAsSeenByLight.w / 2.0f + 0.5f; float diffuseLightingFactor = 0; if ((saturate(ProjectedTexCoords).x == ProjectedTexCoords.x) && (saturate(ProjectedTexCoords).y == ProjectedTexCoords.y)) { float depthStoredInShadowMap = tex2D(ShadowMapSampler, ProjectedTexCoords).r; float realDistance = PSIn.Pos2DAsSeenByLight.z / PSIn.Pos2DAsSeenByLight.w; if ((realDistance - 1.0f / 100.0f) <= depthStoredInShadowMap) { diffuseLightingFactor = DotProduct(xLightPos, PSIn.Position3D, PSIn.Normal); diffuseLightingFactor = saturate(diffuseLightingFactor); diffuseLightingFactor *= xLightPower; } } float4 baseColor = tex2D(Sampler, PSIn.TexCoords); Output.Color = baseColor*(diffuseLightingFactor + xAmbient); return Output; } SMapVertexToPixel ShadowMapVertexShader(float4 inPos : POSITION) { SMapVertexToPixel Output = (SMapVertexToPixel)0; Output.Position = mul(inPos, xLightsWorldViewProjection); Output.Position2D = Output.Position; return Output; } SMapPixelToFrame ShadowMapPixelShader(SMapVertexToPixel PSIn) { SMapPixelToFrame Output = (SMapPixelToFrame)0; Output.Color = PSIn.Position2D.z / PSIn.Position2D.w; return Output; } /* ******************* */ /* END SHADOW MAP CODE */ /* ******************* */ / For rendering without instancing. technique ShadowMap { pass Pass0 { VertexShader = compile vs_2_0 ShadowMapVertexShader(); PixelShader = compile ps_2_0 ShadowMapPixelShader(); } } technique ShadowedScene { /* pass Pass0 { VertexShader = compile vs_2_0 VSBasicTx(); PixelShader = compile ps_2_0 PSBasicTx(); } */ pass Pass1 { VertexShader = compile vs_2_0 ShadowedSceneVertexShader(); PixelShader = compile ps_2_0 ShadowedScenePixelShader(); } } technique SimpleFog { pass Pass0 { VertexShader = compile vs_2_0 VSBasicTx(); PixelShader = compile ps_2_0 PSBasicTx(); } } I edited my fx file , for show you only information and functions about the shadow ;-)

• Should MVVM ViewModel inject an HTML template for default view?

  - by explunit

  I'm working on web application design that includes Knockout.js and have an overall MVVM question: Does it make sense for the ViewModel to automatically inject a default HTML template (pulled from separate file)? More detail: suppose I have a site like this... header... widget 1 widget 2 widget 3 footer ...and widgets 1/2/3 are going to be Knockout.js ViewModels determined at runtime from an overall list of available widgets, each with associated HTML template file. I understand that in MVVM you want the view (HTML template in this case) to be separate from the ViewModel (Javascript file in this case) so that people can edit it separately and possibly provide multiple templates for different "skins". However, it seems like it would also make sense for the ViewModel to point to a default html template that gets automatically used unless the controlling code provides a different one. Am I looking at this correctly? As an example, see this answer on StackOverflow where he recommends injecting the HTML and then the ViewModel. Seems like a one-liner would make more sense in that case, with the possibility of overriding a default template value.

• How do I give a user permisson to view scheduled task history on Server 2008?

  - by pplrppl

  I've set up a scheduled task on Server 2008 and want to run it as a user other than the local administrator. So I choose a domain account created specifically for this task and once I've closed the scheduled task and entered a valid password I want to run it and look a the history tab for this task. On the history tab I see: The user account does not have permission to view task history on this computer. What permission must I grant to allow this user to view history and/or how can I view the history as a local admin/domain admin instead of the user the job will run under? Steps to hopefully reproduce: I'm starting from the "Server Manager" - Configuration - Task Scheduler - Task Scheduler Library. IN the top middle pane I have tasks that have been running for several months as the local administrator. In the process of troubleshooting another issue I changed the task to run as Domain\ABCuser. Later in the process of troubleshooting I tried unchecking "run with highest privileges". I have since changed the job back to SERVERNAME\Administrator but the history tab still showed the permissions message. I may have had multiple Server Manager windows open. After Closing the Server Manager and being sure no other management consoles were open I was able to reopen the Server Manager and see the History tab without error. At this point the task works properly but should I ever need to run a task as a task specific account I'd like to know how to make the history viewable. It may be something as simple as closing all Server Manger windows to allow cached permissions to be refreshed the next time you open the Manager but at this point I don't know exactly what the solution is.

• Help with complex MVVM (multiple views)

  - by jsjslim

  I need help creating view models for the following scenario: Deep, hierarchical data Multiple views for the same set of data Each view is a single, dynamically-changing view, based on the active selection Depending on the value of a property, display different types of tabs in a tab control My questions: Should I create a view-model representation for each view (VM1, VM2, etc)? 1. Yes: a. Should I model the entire hierarchical relationship? (ie, SubVM1, HouseVM1, RoomVM1) b. How do I keep all hierarchies in sync? (e.g, adding/removing nodes) 2. No: a. Do I use a huge, single view model that caters for all views? Here's an example of a single view Figure 1: Multiple views updated based on active room. Notice Tab control Figure 2: Different active room. Multiple views updated. Tab control items changed based on object's property. Figure 3: Different selection type. Entire view changes

• Controlling what data populates STAR

  - by user10747017

  Beginning with the Primavera Reporting Database 2.2\P6 Analytics 1.2 release, the first release that supported the P6 Extended Schema, a new ability was added to filter which projects could be included during an ETL run. In previous releases, all projects were included in an ETL run. Additionally, all projects with the option to enable publication are included in the ETL run by default.Because the reporting needs for P6 Extended Schema are different from those of STAR, you can define a filter that will limit the data that is included in the STAR schema. For example, your STAR schema can be filter to only include all projects in a specific Portfolio, or all projects with a project code assignment of 'For Analytics.'  Any criteria that can be defined in a Where clause and added to a view can be used to filter the projects included in the STAR schema. I highly suggest this approach when dealing with large databases. Unnecessary projects could cause the Extract portion of the ETL process to take longer. A table in STAR called etl_projectlist is the key for what projects are targeted during the ETL process. To setup the filter, perform the following steps:1. Connect to your Primavera P6 Project Management Database as Pxrptuser (extended schema owner) and create a new view:create or replace view star_project_viewasselect PROJECTOBJECTID objectidfrom projectportfolio pp, projectprojectportfolio pppwhere pp.objectid = ppp.PROJECTPORTFOLIOOBJECTIDand pp.name = 'STAR Projects'--The main field that MUST be selected in the view is the projectobjectid. Selecting any other field besides the projectobjectid will cause the view to be invalid and will not work. Any Where clause can be used, but projectobjectid is the key.2. In your STAR installation directory go the \res folder and edit the staretl.properties file.  Here you will define the view to be used.  Add the following line or update if exists:star.project.filter.ds1=star_project_view3. When running the  staretl.cmd or staretl.sh process the database link to Pxrtpuser will be accessed and this view will be used to populate the etl_projectlist table  with the appropriate projectobjectids as defined in the view created in step 1 above.

• Using Groovy Aggregate Functions in ADF BC

  - by Sireesha Pinninti

  This article explains how groovy aggregate functions(sum, count, min, max and avg) can be used in ADF Business components and demonstrates how these can be used at entity and view level Let's consider EMP and DEPT tables and an usecase to track number of employees in each department   Entity-Level To use aggregate functions at entity level, we need to have association between entities representing master and child relationship and the destination accessor name is what we are going to use in our groovy Syntax: <Accessor>.count(Groovyexpression) - Note down the destination accessor name(EMP) in the association or AccessorAttribute name in source entity - Add a transient attribute in source entity with persistent property set to false and provide the groovy expression in the syntax provided above - Finally, Add newly added attribute to view object View-Level To use aggregate functions at view level, we need to have a view link between viewobjects representing master and child relationship and the destination accessor name is what we are going to use in our groovy Syntax: <ViewLinkAccessor>.count(Groovyexpression) - Note down the destination accessor name(EmpView) in the view link or viewLinkAccessor name in source view - Add a transient attribute in view object and provide a groovy aggregate function count as a value to it in the syntax provided above Now, If you run application module tester and execute DeptView / ViewLink, you should see employee count in EmpCount field  In similar way, one can use other groovy aggregate functions sum, avg, min and max.

• MVC and individual elements of the model under a common base class

  - by Stewart

  Admittedly my experience of using the MVC pattern is limited. It might be argued that I don't really separate the V from the C, though I keep the M separate from the VC to the extent I can manage. I'm considering the scenario in which the application's model includes a number of elements that have a common base class. For example, enemy characters in a video game, or shape types in a vector graphics app. The view wants to render these elements. Of course, the different subclasses call for different rendering. The problem is that the elements are part of the model. Rendering them is conceptually part of the view. But how they are to be rendered depends on parameters of both: Attributes and state of the element are parameters of the model User settings are parameters of the view - and to support multiple platforms and/or view modes, different views may be used What's your preferred way of dealing with this? Put the rendering code in the model classes, passing in any view parameters? Put the rendering code in the view, using a switch or similar to select the right rendering for the model element type? Have some intermediate classes as a model-view interface, of which the model will create objects on demand and the view will then render them? Something else?

• Using PDO with MVC

  - by mister martin

  I asked this question at stackoverflow and received no response (closed as duplicate with no answer). I'm experimenting with OOP and I have the following basic MVC layout: class Model { // do database stuff } class View { public function load($filename, $data = array()) { if(!empty($data)) { extract($data); } require_once('views/header.php'); require_once("views/$filename"); require_once('views/footer.php'); } } class Controller { public $model; public $view; function __construct() { $this->model = new Model(); $this->view = new View(); // determine what page we're on $page = isset($_GET['view']) ? $_GET['view'] : 'home'; $this->display($page); } public function display($page) { switch($page) { case 'home': $this->view->load('home.php'); break; } } } These classes are brought together in my setup file: // start session session_start(); require_once('Model.php'); require_once('View.php'); require_once('Controller.php'); new Controller(); Now where do I place my database connection code and how do I pass the connection onto the model? try { $db = new PDO('mysql:host='.DB_HOST.';dbname='.DB_DATABASE.'', DB_USERNAME, DB_PASSWORD); $db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch(PDOException $err) { die($err->getMessage()); } I've read about Dependency Injection, factories and miscellaneous other design patterns talking about keeping SQL out of the model, but it's all over my head using abstract examples. Can someone please just show me a straight-forward practical example?

• Is it possible to use Google Docs Viewer to view files already in Google Docs?

  - by john2x

  The title is a little confusing. I'll elaborate. As far as I can tell, the Google Docs Viewer tool accepts a link to a raw document file (e.g. .doc, .pdf, et. al.), and renders its contents in the browser. For example, this url to a pdf http://research.google.com/archive/bigtable-osdi06.pdf when passed to Viewer, returns this link: http://docs.google.com/viewer?url=http%3A%2F%2Fresearch.google.com%2Farchive%2Fbigtable-osdi06.pdf What I'm trying to achieve is, use the Viewer to view a document already hosted in Google Docs (i.e. no longer a raw document file). When passing a link to a Google Docs document to the Viewer, the result is not as expected. It renders the link's HTML source instead of the document's contents. The reason I want to do this is that I want to be able to use the "embed" feature of Viewer to view Google Docs documents. Does Google Docs have a "link to embeddable view" feature? P.S. Here is a sample snippet to an embedded document. This is what I want, but pointing to an existing Google Docs document. <iframe src="http://docs.google.com/viewer?url=http%3A%2F%2Fresearch.google.com%2Farchive%2Fbigtable-osdi06.pdf&embedded=true" width="600" height="780" style="border: none;"></iframe>

• Odd one: IE6 showing the "view source" command enabled when I was expecting it to be disabled.

  - by caerphilly

  Hi, OK, I admit this problem is odd. I'm just trying to understand why IE is behaving the way it is. I realise that logic may not apply here :) I have Internet Explorer 6 (Sp1) running on Windows 2000. The IE option "Do not store encrypted pages to disk" is checked (enabled). The temporary internet files folder is empty. TEMP and TMP environment variables are set to valid folders. I'm connected to a web server over SSL. The web server is serving a page over SSL with the HTTP cache-control header set to "no-cache, no-store". I was expecting the "view source" command to be greyed out in this circumstance (as it is on another machine). But it works. When I "view source", I get an entry in the Temporary Internet Files folder with an "internet address" property of "view-source:https://myserver/...." and the content of the page. I wasn't expecting that. I can't understand why one machine is different to another in this regard. Obviously there is some environment/setup difference, but I can't track it down. Anyone have any bright ideas?

• Which are the best ways to organize view hierarchies in GUI interfaces?

  - by none

  I'm currently trying to figure out the best techniques for organizing GUI view hierarchies, that is dividing a window into several panels which are in turn divided into other components. I've given a look to the Composite Design Pattern, but I don't know if I can find better alternatives, so I'd appreciate to know if using the Composite is a good idea, or it would be better looking for some other techniques. I'm currently developing in Java Swing, but I don't think that the framework or the language can have a great impact on this. Any help will be appreciated. ---------EDIT------------ I was currently developing a frame containing three labels, one button and a text field. At the button pressed, the content inside the text field would be searched, and the results written inside the three labels. One of my typical structure would be the following: MainWindow | Main panel | Panel with text field and labels. | Panel with search button Now, as the title explains, I was looking for a suitable way of organizing both the MainPanel and the other two panels. But here came problems, since I'm not sure whether organizing them like attributes or storing inside some data structure (i.e. LinkedList or something like this). Anyway, I don't really think that both my solution are really good, so I'm wondering if there are really better approaches for facing this kind of problems. Hope it helps

• Building a modular Website with Zend Framework: Am I on the right way?

  - by Oliver

  Hi, i´m a little bit confused by reading all this posts an tutorials about staring with Zend, because there a so many different ways to solve a problem. I only need a feedback about my code to know if iam on the right way: To simply get a (hard coded) Navigation for my side (depending on who is logged in) i build a Controller Plugin with a postDispatch method that holds following code: public function postDispatch(Zend_Controller_Request_Abstract $request) { $menu = new Menu(); //Render menu in menu.phtml $view = new Zend_View(); //NEW view -> add View Helper $prefix = 'My_View_Helper'; $dir = dirname(__FILE__).'/../../View/Helper/'; $view->addHelperPath($dir,$prefix); $view->setScriptPath('../application/default/views/scripts/menu'); $view->menu = $menu->getMenu(); $this->getResponse()->insert('menu', $view->render('menu.phtml')); } Is it right that i need to set the helper path once again? I did this in a Plugin Controller named ViewSetup. There i do some setup for the view like doctype, headlinks, helper paths...(This step is from the book: Zend Framework in Action) The Menu class which is initiated looks like this: class Menu { protected $_menu = array(); /** * Menu for notloggedin and logged in */ public function getMenu() { $auth = Zend_Auth::getInstance(); $view = new Zend_View(); //check if user is logged in if(!$auth->hasIdentity()) { $this->_menu = array( 'page1' => array( 'label' => 'page1', 'title' => 'page1', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page1')) ), 'page2' => array( 'label' => 'page2', 'title' => 'page2', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page2')) ), 'page3' => array( 'label' => 'page3', 'title' => 'page3', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page3')) ), 'page4' => array( 'label' => 'page4', 'title' => 'page4', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page4')) ), 'page5' => array( 'label' => 'page5', 'title' => 'page5', 'url' => $view->url(array('module' => 'pages','controller' => 'my', 'action' => 'page5')) ) ); } else { //user is vom type 'client' //.. } return $this->_menu; } } Here´s my view script: <ul id="mainmenu"> <?php echo $this->partialLoop('menuItem.phtml',$this->menu) ?> </ul> This is working so far. My question is: is it usual to do it this way, is there anything to improve? I´m new to Zend and in the web are many deprecated tutorials which often is not obvious. Even the book is already deprecated where the autoloader is mentioned. Many thanks in advance

• Asp.net mvc, view with multiple updatable parts - how?

  - by DerDres

  I have started doing asp.net mvc programming and like it more everyday. Most of the examples I have seen use separate views for viewing and editing details of a specific entity. E.g. - table of music albums linking to separate 'detail' and 'update' views [Action] | Title | Artist detail, update | Uuuh Baby | Barry White detail, update | Mr Mojo | Barry White With mvc how can I achieve a design where the R and the U (CRUD) are represented in a single view, and furthermore where the user can edit separate parts of the view, thus limiting the amount of data the user can edit before saving? Example mockup - editing album detials: I have achieved such a design with ajax calls, but Im curious how to do this without ajax. Parts of my own take on this can be seen below. I use a flag (enum EditCode) indicating which part of the view, if any, that has to render a form. Is such a design in accordance with the framework, could it be done more elegantly? AlbumController public class AlbumController : Controller { public ActionResult Index() { var albumDetails = from ManageVM in state.AlbumState.ToList() select ManageVM.Value.Detail; return View(albumDetails); } public ActionResult Manage(int albumId, EditCode editCode) { (state.AlbumState[albumId] as ManageVM).EditCode = (EditCode)editCode; ViewData["albumId"] = albumId; return View(state.AlbumState[albumId]); } [HttpGet] public ActionResult Edit(int albumId, EditCode editCode) { return RedirectToAction("Manage", new { albumId = albumId, editCode = editCode }); } // edit album details [HttpPost] public ActionResult EditDetail(int albumId, Detail details) { (state.AlbumState[albumId] as ManageVM).Detail = details; return RedirectToAction("Manage", new { albumId = albumId, editCode = EditCode.NoEdit });// zero being standard } // edit album thought [HttpPost] public ActionResult EditThoughts(int albumId, List<Thought> thoughts) { (state.AlbumState[albumId] as ManageVM).Thoughts = thoughts; return RedirectToAction("Manage", new { albumId = albumId, editCode = EditCode.NoEdit });// zero being standard } Flag - EditCode public enum EditCode { NoEdit, Details, Genres, Thoughts } Mangae view <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcApplication1.Controllers.ManageVM>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Manage </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Manage</h2> <% if(Model.EditCode == MvcApplication1.Controllers.EditCode.Details) {%> <% Html.RenderPartial("_EditDetails", Model.Detail); %> <% }else{%> <% Html.RenderPartial("_ShowDetails", Model.Detail); %> <% } %> <hr /> <% if(Model.EditCode == MvcApplication1.Controllers.EditCode.Thoughts) {%> <% Html.RenderPartial("_EditThoughts", Model.Thoughts); %> <% }else{%> <% Html.RenderPartial("_ShowThoughts", Model.Thoughts); %> <% } %>

• Need multiple views to respond to a touch event in an iPhone app

  - by Joel

  Setup: I have two views that I need to respond to the touch event, and they are layered out on top of one another. View 1 is on top of View 2. View 2 is a UIWebView. View 1 is sublclassed to capture the touch event. My problem is that if I try to call the UIWebView event handlers (touchesBegan: and touchesEnded:) from within the event handlers of View 1, which is the first responder, nothing happens. However if I set View 1 to userInteractionEnabled = NO, then the touch goes through that view and is processed properly by the 2nd view. Any ideas on how I can have 2 views respond to a touch event? Unfortunately the 2nd view is a UIWebView, so I need to actually call the event handler and not a different method, etc... Thanks in advance for any advice, Joel

Then the presenter calls View.Init to pass himself to the view. I was wondering however if there is a way to let the container fix my circular reference (view - presenter, presenter - view). class Presenter : IPresenter { private View _view; public Presenter(IView view, ...){ _view = view; _view.Init(this) } } class View : IView { private IPresenter _presenter; public void Init(IPresenter presenter){ _presenter = presenter; } } Kind regards Frederik

• Self-type mismatch in Scala

  - by Alexey Romanov

  Given this: abstract class ViewPresenterPair { type V <: View type P <: Presenter trait View {self: V => val presenter: P } trait Presenter {self: P => var view: V } } I am trying to define an implementation in this way: case class SensorViewPresenter[T] extends ViewPresenterPair { type V = SensorView[T] type P = SensorPresenter[T] trait SensorView[T] extends View { } class SensorViewImpl[T](val presenter: P) extends SensorView[T] { presenter.view = this } class SensorPresenter[T] extends Presenter { var view: V } } Which gives me the following errors: error: illegal inheritance; self-type SensorViewPresenter.this.SensorView[T] does not conform to SensorViewPresenter.this.View's selftype SensorViewPresenter.this.V trait SensorView[T] extends View { ^ <console>:13: error: type mismatch; found : SensorViewPresenter.this.SensorViewImpl[T] required: SensorViewPresenter.this.V presenter.view = this ^ <console>:16: error: illegal inheritance; self-type SensorViewPresenter.this.SensorPresenter[T] does not conform to SensorViewPresenter.this.Presenter's selftype SensorViewPresenter.this.P class SensorPresenter[T] extends Presenter { ^ I don't understand why. After all, V is just an alias for SensorView[T], and the paths are the same, so how can it not conform?

• UITableView becomes invisible after changing data in it

  - by Alexander Shemshurenko

  Hi I have application with TabBar that control several views. In one view i control connection to different servers.Each server provides different set of items. I display these items in UITableView on other view. I create table view like this UITableView * aTableView = [[UITableView alloc] initWithFrame:CGRectMake(X,Y,Width,Height) style:UITableViewStyleGrouped]; [[self view] addSubview:aTableView]; aTableView.da taSource = self; The problem is that Table view displayed ok first time , but if i go back to view number one and change server(changing list of items that should be displayed in table view), table view becomes invisible for some reason. If i tap on the screen in place where it should be, its becomes visible again. Ive tried to call to reloadData and setNeedDisplay in viewWillAppear of the UIViewController that hosts this table view, but without success. Any advice? Thanks
