  • ASP.NET MVC: ModelState vs. ModelStateDictionary

    - by Alex
    Hello, I have a service which has a method that's called when a certain controller method is triggered. My service returns a custom result object PlacementResult in which I want to communicate errors that may have happened (validation) back to the controller method. Should PlacementResult have a ModelState or a ModelStateDictionary to communicate errors back to the controller (and finally view)? How would I string this together? Finally, how do I get the ModelState/ModelStateDictionary (whichever you tell me I should choose) back into the view (highlighting the appropriate text box, show the error message etc.)? Thank you !

  • ajax in zend frame work

    - by rookie
    Hi, I am new to Zend Frame Work. I am using $ajaxContext = $this-_helper-getHelper('AjaxContext'); for adding action contexts. I have one Index.phtml page and all other views are ajax.phtml pages. I have to do some java script methods in the ajax.phtml pages. But i didn't find a way to refer the js files in the ajax.phtml pages. I have tried adding those in the controller init and index action, using $this-view-headScript()-appendFile, though i have the reference added in the page source, none of htese seems to be working on the ajax content. Then i tried to add it in the action for the ajax page, then it is not coming in the page source itself. As far as i understood, $this-view-headScript()-appendFile will append the file reference to the layout page and for the ajax.phtml pages, the layout will be disabled. Is there any way that i can refer my js files in the ajax.phtml pages?

  • ASP.NET MVC Web structure

    - by ile
    This is database structure. It is used to build simple cms in asp.net mvc. Before I run deeper into developing site, I want to make sure if this would be "correct" web structure: Articles: Controllers folder: Create controllers ArticleCategoryController and ArticleController Models folder: ArticleCategoryRepository and ArticleRepository View folder: ArticleCategory folder (Create.aspx, Edit.aspx, Index.aspx, Details.aspx); Article folder (Create.aspx, Edit.aspx, Index.aspx, Details.aspx) Photos: Controllers folder: Create controllers PhotoAlbumController and PhotoController Models folder: PhotoAlbumRepository and PhotoRepository View folder: PhotoAlbum folder (Create.aspx, Edit.aspx, Index.aspx, Details.aspx); Photo folder (Create.aspx, Edit.aspx, Index.aspx, Details.aspx) and so on... Is there a better way or this is ok? Thanks. Ile

  • HTML table headers always visible at top of window when viewing a large table

    - by Craig McQueen
    I would like to be able to "tweak" an HTML table's presentation to add a single feature: when scrolling down through the page so that the table is on the screen but the header rows are off-screen, I would like the headers to remain visible at the top of the viewing area. This would be conceptually like the "freeze panes" feature in Excel. However, an HTML page might contain several tables in it and I only would want it to happen for the table that is currently in-view, only while it is in-view. Note: I've seen one solution where the table data area is made scrollable while the headers do not scroll. That's not the solution I'm looking for.

  • How create widget with clickable text in QT/PyQt?

    - by serge
    Hi everyone, i'm trying to realize non-editable QTableView with widgets in cells that should contain clickable listed text. With following code i'm setting widget in definite cell: view = QTableView() label = QLabel( <some html text> ) ... view.setIndexWidget(index, label) I used html to make label's text clickable, but links became blue with underline and moreover by clicking on it with right mouse button appears popup menu with "Copy Link Locaion" option, where i wanted to place some hidden information instead of url and of course do not let user see this info. I'm looking for light-weight widget, i thought that insertion of QGraphicsView in each cell will lead to big computer loads, but can't think of any other solution. Can you advice what should i use for this purpose? Thank you in advance Serge

  • Alternative Menu Items in NSMenu

    - by Nick Paulson
    Hi, I have an NSMenu that contains NSMenuItems with custom views. I want it so that when the alt button is pressed, the menu items would change part of their look (through their view). I found setAlternative in the NSMenuItem docs, however, in practice I could only get it to work with NSMenuItems without custom views. As soon as I set a custom view, all of the menu items would be displayed. Also, I tried getting keypress events while the menu was open. Due to the other run loop, NSApplication's sendEvent: doesn't receive events until after the menu is closed. Therefore, I can't just intercept the event coming in. Does anyone know how I can get notified, whether through delegation or subclassing, of when the alt key is pressed when a menu is opened?

  • Asyncronously receiving data in an ASP.NET MVC application

    - by Mitciv
    I'm looking for the best way to constantly check if data has been sent to our ASP.NET MVC application from a server. I would like to asynchronously check for data and update the view when data has been read. I'm currently using a TcpClient to make a connection, and making the connection in the inherited custom base controller. Currently though I have to refresh the page for the updating of the view to take place. Would there be a proper AJAX solution? or do I need to move the connection to the ActionMethod?

  • getView() (for a Custom ListView ) doesn't get called on notifyDatasetChanged()

    - by hungson175
    Hi everyone, I have the following problem, and searched for a while but haven't got any solution from the net: I have a custom list view, each item has the following layout (I just post the essential): <LinearLayout> <ImageView android:id="@+id/friendlist_iv_avatar" /> <TextView andorid:id="@+id/friendlist_tv_nick_name" /> <ImageView android:id="@+id/friendlist_iv_status_icon" /> </LinearLayout> And I have a class FriendRowItem, which is inflated from the above layout: public class FriendRowItem extends LinearLayout{ private ImageView ivAvatar; private ImageView ivStatusIcon; private TextView tvNickName; public FriendRowItem(Context context) { super(context); RelativeLayout friendRow = (RelativeLayout) Helpers.inflate(context, R.layout.friendlist_row); this.addView(friendRow); ivAvatar = (ImageView)findViewById(R.id.friendlist_iv_avatar); ivStatusIcon = (ImageView)findViewById(R.id.friendlist_iv_status_icon); tvNickName = (TextView)findViewById(R.id.friendlist_tv_nick_name); } public void setPropeties(Friend friend) { //Avatar ivAvatar.setImageResource(friend.getAvatar().getDrawableResourceId()); //Status Status.Type status = friend.getStatusType(); if ( status == Type.ONLINE) { ivStatusIcon.setImageResource(R.drawable.online_icon); } else { ivStatusIcon.setImageResource(R.drawable.offline_icon); } //Nickname String name = friend.getChatID(); if ( friend.hasName()) { name = friend.getName(); } tvNickName.setText(name); } } In the main activity, I have a custom listview: lvMainListView, with an custom adapter (whose class extends ArrayAdapter - and off course: override the method getView ), the data set of the adapter is: ArrayList<Friend> friends: private class FriendRowAdapter extends ArrayAdapter<Friend> { public FriendRowAdapter(Context applicationContext, int friendlistRow, ArrayList<Friend> friends) { super(applicationContext, friendlistRow, friends); } @Override public View getView(int position,View convertView,ViewGroup parent) { Friend friend = getItem(position); FriendRowItem row = (FriendRowItem) convertView; if ( row == null ) { row = new FriendRowItem(ShowFriendsList.this.getApplicationContext()); } row.setPropeties( friend ); return row; } } the problem is when I change the status of a friend from OFFLINE to ONLINE, then call notifyDataSetChanged(), nothing happens : the status icon of that friend doesn't change. I tried debugging, and saw the code: notifyDataSetChanged() get called, but the custom getView() is not fired ! Can you please tell me, that is normal in Android, or did I do something wrong ? (I am using Android 1.5). Thank you in advance, Son

  • How to implement UIViewController rotation in response to orientation changes?

    - by Greg Maletic
    My app has about 10 different UIViewControllers, just one of which I want to switch to landscape mode if the device is rotated. (All the rest, I want to keep in portrait.) In order to implement rotation on that one view, I needed to implement its controller's 'shouldAutorotate' method and return YES. Since this view is accessed via a navigation controller, I also needed to create a subclass of UINavigationController that implements 'shouldAutorotate' and return YES. This solution works, but too well. I find that all of the UIViewControllers I push onto my subclass of UINavigationController respond to rotation, even if I implement 'shouldAutorotate' and return NO. (Remember: I only want one particular UIViewController to respond to rotation, not every one in the navigation controller's stack.) So, my question is: how do I best do this? All the solutions I can come up with seem 1) cumbersome, and 2) worse, don't seem to work. Thanks very much.

  • Data Quality Through Data Governance

    Data Quality Governance Data quality is very important to every organization, bad data cost an organization time, money, and resources that could be prevented if the proper governance was put in to place.  Data Governance Program Criteria: Support from Executive Management and all Business Units Data Stewardship Program  Cross Functional Team of Data Stewards Data Governance Committee Quality Structured Data It should go without saying but any successful project in today’s business world must get buy in from executive management and all stakeholders involved with the project. If management does not fully support a project because they see it is in there and the company’s best interest then they will remove/eliminate funding, resources and allocated time to work on the project. In essence they can render a project dead until it is official killed by the business. In addition, buy in from stake holders is also very important because they can cause delays increased spending in time, money and resources because they do not support a project. Data Stewardship programs are administered by a data steward manager who primary focus is to support, train and manage a cross functional data stewards team. A cross functional team of data stewards are pulled from various departments act to ensure that all systems work to ensure that an organization’s goals are achieved. Typically, data stewards are subject matter experts that act as mediators between their respective departments and IT. Data Quality Procedures Data Governance Committees are composed of data stewards, Upper management, IT Leadership and various subject matter experts depending on a company. The primary goal of this committee is to define strategic goals, coordinate activities, set data standards and offer data guidelines for the business. Data Quality Policies In 1997, Claudia Imhoff defined a Data Stewardship’s responsibility as to approve business naming standards, develop consistent data definitions, determine data aliases, develop standard calculations and derivations, document the business rules of the corporation, monitor the quality of the data in the data warehouse, define security requirements, and so forth. She further explains data stewards responsible for creating and enforcing polices on the following but not limited to issues. Resolving Data Integration Issues Determining Data Security Documenting Data Definitions, Calculations, Summarizations, etc. Maintaining/Updating Business Rules Analyzing and Improving Data Quality

  • touchesEnded not being called??? or randomly being called

    - by Rob
    If I lift my finger up off the first touch, then it will recognize the next touch just fine. It's only when I hold my first touch down continuously and then try and touch a different area with a different finger at the same time. It will then incorrectly register that second touch as being from the first touch again. Update It has something to do with touchesEnded not being called until the very LAST touch has ended (it doesn't care if you already had 5 other touches end before you finally let go of the last one... it calls them all to end once the very last touch ends) - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; NSString* filename = [listOfStuff objectAtIndex:[touch view].tag]; // do something with the filename now } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { ITouch* touch = [touches anyObject]; NSString* buttonPressed = [listOfStuff objectAtIndex:[touch view].tag]; // do something with this info now }

  • ASP .NET MVC; return HTML along with JavaScript

    - by effkay
    I have a partial view which renders a table. On page load, I am using JQuery to perform Zebra Stripping on it. Whenever ajax refreshes the table, DOM elements are updated, but since JQuery code to do the Zebra Stripping is not executed; table looks ugly. I have tried adding Javascript in my partial view if( Request.IsAjaxRequest() ) return PartialView( "AdministrationGrid", Users ); but javascript is not executed. I guess the only way to execute the Javascript as reply is to do: return JavaScript( "alert( '' )" ); Anyone with an idea how can I achieve this? I thought about JQuery Live, but it is used to bind itself to events.

  • How load text into JavaStackTraceConsolePage programmatically?

    - by Marcel
    In my Eclipse plugin I'd like to send a Java console output (loaded from some other system) to the Java Stack Trace Console. I pseudo-code it'd be something like: get the console output from the other system obtain a reference to a JavaStackTraceConsolePage instance send the text to the console page display the console i.e. switch from my plugin's view to the Console view Step 1 is easy as it is specific to my plugin. As for the rest I'm pretty much clueless - Google and stackoverflow.com don't come up with useful references or how-tos. Since the class JavaStackTraceConsolePage is part of an internal Eclipse API (org.eclipse.jdt.internal.debug.ui.console) I'm not even sure whether it's doable at all.

  • Rails 3, changing a specific value in a row

    - by Elliot
    Hey Guys, This question seems ridiculously easy, but I seem to be stuck. Lets say we have a table "Books" Each Book, has a name, description, and a status. Lets say I want to create link in the show view, that when clicked, solely changes the status (to "read") for example. So far, I've tried adding a block in the controller, that says: def read @book = Book.find(params[:id]) @book.status = "Read" @book.update_attributes(params[:book]) respond_to do |format| format.html { redirect_to :back} format.xml { render :xml => @book } end end Then I've added a link to the view that is like: <%= link_to "Read", read_book_path(@book), :method = :put % This isn't working at all. I have added it to my routes, but it doesn't seem to matter. Any help would be great! Thanks! -Elliot EDIT: Forgot to add I'm getting a NoMethodError: undefined method `read_book_path'

  • Memory leak in WPF app due to DelegateCommand.

    - by Abdullah BaMusa
    I just finished desktop apps written in WPF and c# using MVVM pattern. In this app I used Delegate Command implementation to wrap the ICommands properties exposed in my ModelView. The problem is these DelegateCommands prevent my ModelView and View from being garbage collected after closing the view. So it stays larking until I terminate the whole application. I profile the application I find it’s all about delegatecommand that keeping the modelview in memory. How could I avoid this situation and is this in nature of mvvm pattern, or it’s about my implantation of the pattern?. Thanks

  • Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell

    - by SQLOS Team
    Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell Blog This blog post comes from Khalid Mouss, Senior Program Manager in Microsoft SQL Server. Overview The goal of this blog is to demonstrate how we can automate through PowerShell connecting multiple SQL Server deployments in Windows Azure Virtual Machines. We would configure TCP port that we would open (and close) though Windows firewall from a remote PowerShell session to the Virtual Machine (VM). This will demonstrate how to take the advantage of the remote PowerShell support in Windows Azure Virtual Machines to automate the steps required to connect SQL Server in the same cloud service and in different cloud services.  Scenario 1: VMs connected through the same Cloud Service 2 Virtual machines configured in the same cloud service. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually required. Step 1 – Provision VMs and Configure Ports   Provision VM1; named DemoVM1 as follows (see examples screenshots below if using the portal):   Provision VM2 (DemoVM2) with PowerShell Remoting enabled and connected to DemoVM1 above (see examples screenshots below if using the portal): After provisioning of the 2 VMs above, here is the default port configurations for example: Step2 – Verify / Confirm the TCP port used by the database Engine By the default, the port will be configured to be 1433 – this can be changed to a different port number if desired.   1. RDP to each of the VMs created below – this will also ensure the VMs complete SysPrep(ing) and complete configuration 2. Go to SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for <SQL instance> -> TCP/IP - > IP Addresses   3. Confirm the port number used by SQL Server Engine; in this case 1433 4. Update from Windows Authentication to Mixed mode   5.       Restart SQL Server service for the change to take effect 6.       Repeat steps 3., 4., and 5. For the second VM: DemoVM2 Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <username> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) Your will then be prompted to enter the password. Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok. Step 5 – Now connect from DemoVM2 to DB instance in DemoVM1 Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.   Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can longer connect from VM3 remotely to VM1. Scenario 2: VMs provisioned in different Cloud Services 2 Virtual machines configured in different cloud services. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on on-premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually needed. Step 1 – Provision new VM3 Provision VM3; named DemoVM3 as follows (see examples screenshots below if using the portal): After provisioning is complete, here is the default port configurations: Step 2 – Add public port to VM1 connect to from VM3’s DB instance Since VM3 and VM1 are not connected in the same cloud service, we will need to specify the full DNS address while connecting between the machines which includes the public port. We shall add a public port 57000 in this case that is linked to private port 1433 which will be used later to connect to the DB instance. Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <UserName> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) You will then be prompted to enter the password.   Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: Ok. netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok.   Step 5 – Now connect from DemoVM3 to DB instance in DemoVM1 RDP into VM3, launch SSM and Connect to VM1’s DB instance as follows. You must specify the full server name using the DNS address and public port number configured above. Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port   Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.  Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can no longer connect from VM3 remotely to VM1. Conclusion Through the new support for remote PowerShell in Windows Azure Virtual Machines, one can script and automate many Virtual Machine and SQL management tasks. In this blog, we have demonstrated, how to start a remote PowerShell session, re-configure Virtual Machine firewall to allow (or disallow) SQL Server connections.

  • Custom property editors do not work for request parameters in Spring MVC?

    - by dvd
    Hello, I'm trying to create a multiaction web controller using Spring annotations. This controller will be responsible for adding and removing user profiles and preparing reference data for the jsp page. @Controller public class ManageProfilesController { @InitBinder public void initBinder(WebDataBinder binder) { binder.registerCustomEditor(UserAccount.class,"account", new UserAccountPropertyEditor(userManager)); binder.registerCustomEditor(Profile.class, "profile", new ProfilePropertyEditor(profileManager)); logger.info("Editors registered"); } @RequestMapping("remove") public void up( @RequestParam("account") UserAccount account, @RequestParam("profile") Profile profile) { ... } @RequestMapping("") public ModelAndView defaultView(@RequestParam("account") UserAccount account) { logger.info("Default view handling"); ModelAndView mav = new ModelAndView(); logger.info(account.getLogin()); mav.addObject("account", account); mav.addObject("profiles", profileManager.getProfiles()); mav.setViewName(view); return mav; } ... } Here is the part of my webContext.xml file: <context:component-scan base-package="ru.mirea.rea.webapp.controllers" /> <context:annotation-config/> <bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"> <property name="mappings"> <value> ... /home/users/manageProfiles=users.manageProfilesController </value> </property> </bean> <bean id="users.manageProfilesController" class="ru.mirea.rea.webapp.controllers.users.ManageProfilesController"> <property name="view" value="home\users\manageProfiles"/> </bean> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" /> However, when i open the mapped url, i get exception: java.lang.IllegalArgumentException: Cannot convert value of type [java.lang.String] to required type [ru.mirea.rea.model.UserAccount]: no matching editors or conversion strategy found I use spring 2.5.6 and plan to move to the Spring 3.0 in some not very distant future. However, according to this JIRA https://jira.springsource.org/browse/SPR-4182 it should be possible already in spring 2.5.1. The debug shows that the InitBinder method is correctly called. What am i doing wrong?
