Setup Convergence Address Book DisplayName Lookup

- by user13332755

At Convergence Address Book the default lookup for 'Display Name' is the LDAP attribute 'cn', which leads into confusion if you start to setup 'displayName' LDAP attributes for your users. LDAP User Entry with diaplyName attribute: This behavior can be controlled by the configuration file xlate-inetorgperson.xml. Change the default value of XPATH abperson\entry\displayname from 'cn' to 'displayName'. <convergence_deploy_location>/config/templates/ab/corp-dir/xlate-inetorgperson.xml Note: In case the user has no 'displayName' attribute in LDAP you might noticed '...' at the user entry, if found via 'mail' attribute.

Wondering why DisplayName attribute is ignored in LabelFor on an overridden property

- by Lasse Krantz

Hi, today I got confused when doing a couple of <%=Html.LabelFor(m=>m.MyProperty)%> in ASP.NET MVC 2 and using the [DisplayName("Show this instead of MyProperty")] attribute from System.ComponentModel. As it turned out, when I put the attribute on an overridden property, LabelFor didn't seem to notice it. However, the [Required] attribute works fine on the overridden property, and the generated errormessage actually uses the DisplayNameAttribute. This is some trivial examplecode, the more realistic scenario is that I have a databasemodel separate from the viewmodel, but for convenience, I'd like to inherit from the databasemodel, add View-only properties and decorating the viewmodel with the attributes for the UI. public class POCOWithoutDataAnnotations { public virtual string PleaseOverrideMe { get; set; } } public class EditModel : POCOWithoutDataAnnotations { [Required] [DisplayName("This should be as label for please override me!")] public override string PleaseOverrideMe { get { return base.PleaseOverrideMe; } set { base.PleaseOverrideMe = value; } } [Required] [DisplayName("This property exists only in EditModel")] public string NonOverriddenProp { get; set; } } The strongly typed ViewPage<EditModel> contains: <div class="editor-label"> <%= Html.LabelFor(model => model.PleaseOverrideMe) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.PleaseOverrideMe) %> <%= Html.ValidationMessageFor(model => model.PleaseOverrideMe) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.NonOverriddenProp) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.NonOverriddenProp) %> <%= Html.ValidationMessageFor(model => model.NonOverriddenProp) %> </div> The labels are then displayed as "PleaseOverrideMe" (not using the DisplayNameAttribute) and "This property exists only in EditModel" (using the DisplayNameAttribute) when viewing the page. If I post with empty values, triggering the validation with this ActionMethod: [HttpPost] public ActionResult Edit(EditModel model) { if (!ModelState.IsValid) return View(model); return View("Thanks"); } the <%= Html.ValidationMessageFor(model => model.PleaseOverrideMe) %> actually uses [DisplayName("This should be as label for please override me!")] attribute, and produces the default errortext "The This should be as label for please override me! field is required." Would some friendly soul shed some light on this?

DisplayName attribute from Resources?

- by Palantir

Hello! I have a localized application, and I am wondering if it is possible to have the DisplayName for a certain model property set from a Resource. I'd like to do something like this: public class MyModel { [Required] [DisplayName(Resources.Resources.labelForName)] public string name{ get; set; } } But I can't to it, as the compiler says: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type" :( Are there any workarounds? I am outputting labels manually, but I need these for the validator output!

How to use multiple DisplayName attribute using Entity Framework and ASP.Net Mvc 2

- by Picflight

Depending on where I use my Class, I want to be able to show a different DisplayName. I have the following class: [MetadataType(typeof(PortalMetaData))] [System.Web.Mvc.Bind(Exclude = "PortalId")] public partial class Portal { public Portal() { this.Created = DateTime.Now; } } public class PortalMetaData { [Required(ErrorMessage = "Portal name is required")] [StringLength(50, ErrorMessage = "Portal name must be under 50 characters")] public object PortalName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } I have a corresponding Table in the database Portal I use the Portal table with a PortalController for the Site Admin to update the records in the Portal Table. I want another user with a different Role (AsstAdmin) to be able to update this table as well. To facilitate that I am thinking of creating a separate partial class that somehow links back to the Portal Model. This would allow me to display limited Fields for update by the AsstAdmin and I can display a different name for the Field as well. How can I accomplish this task? If I add the following class which inherits from Portal than I get an exception: Unable to cast object of type 'Project1.Mvc.Models.Portal' to type 'Prpject1.Mvc.Models.Site'. [MetadataType(typeof(SiteMetaData))] public class Site : Portal { public Site() { } } public class SiteMetaData { [Required(DisplayName = "Site Description")] public object Description { get; set; } }

ASP.NET MVC localization DisplayNameAttribute alternatives: a good way

- by Brian Schroer

The ASP.NET MVC HTML helper methods like .LabelFor and .EditorFor use model metadata to autogenerate labels for model properties. By default it uses the property name for the label text, but if that’s not appropriate, you can use a DisplayName attribute to specify the desired label text: [DisplayName("Remember me?")] public bool RememberMe { get; set; } I’m working on a multi-language web site, so the labels need to be localized. I tried pointing the DisplayName attribute to a resource string: [DisplayName(MyResource.RememberMe)] public bool RememberMe { get; set; } …but that results in the compiler error "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type”. I got around this by creating a custom LocalizedDisplayNameAttribute class that inherits from DisplayNameAttribute: 1: public class LocalizedDisplayNameAttribute : DisplayNameAttribute 2: { 3: public LocalizedDisplayNameAttribute(string resourceKey) 4: { 5: ResourceKey = resourceKey; 6: } 7: 8: public override string DisplayName 9: { 10: get 11: { 12: string displayName = MyResource.ResourceManager.GetString(ResourceKey); 13: 14: return string.IsNullOrEmpty(displayName) 15: ? string.Format("[[{0}]]", ResourceKey) 16: : displayName; 17: } 18: } 19: 20: private string ResourceKey { get; set; } 21: } Instead of a display string, it takes a constructor argument of a resource key. The DisplayName method is overridden to get the display string from the resource file (line 12). If the key is not found, I return a formatted string containing the key (e.g. “[[RememberMe]]”) so I can tell by looking at my web pages which resource keys I haven’t defined yet (line 15). The usage of my custom attribute in the model looks like this: [LocalizedDisplayName("RememberMe")] public bool RememberMe { get; set; } That was my first attempt at localized display names, and it’s a technique that I still use in some cases, but in my next post I’ll talk about the method that I now prefer, a custom DataAnnotationsModelMetadataProvider class…

A basic T4 template for generating Model Metadata in ASP.NET MVC2

- by rajbk

I have been learning about T4 templates recently by looking at the awesome ADO.NET POCO entity generator. By using the POCO entity generator template as a base, I created a T4 template which generates metadata classes for a given Entity Data Model. This speeds coding by reducing the amount of typing required when creating view specific model and its metadata. To use this template, Download the template provided at the bottom. Set two values in the template file. The first one should point to the EDM you wish to generate metadata for. The second is used to suffix the namespace and classes that get generated. string inputFile = @"Northwind.edmx"; string suffix = "AutoMetadata"; Add the template to your MVC 2 Visual Studio 2010 project. Once you add it, a number of classes will get added to your project based on the number of entities you have. One of these classes is shown below. Note that the DisplayName, Required and StringLength attributes have been added by the t4 template. //------------------------------------------------------------------------------ // <auto-generated> // This code was generated from a template. // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // </auto-generated> //------------------------------------------------------------------------------ using System; using System.ComponentModel; using System.ComponentModel.DataAnnotations; namespace NorthwindSales.ModelsAutoMetadata { public partial class CustomerAutoMetadata { [DisplayName("Customer ID")] [Required] [StringLength(5)] public string CustomerID { get; set; } [DisplayName("Company Name")] [Required] [StringLength(40)] public string CompanyName { get; set; } [DisplayName("Contact Name")] [StringLength(30)] public string ContactName { get; set; } [DisplayName("Contact Title")] [StringLength(30)] public string ContactTitle { get; set; } [DisplayName("Address")] [StringLength(60)] public string Address { get; set; } [DisplayName("City")] [StringLength(15)] public string City { get; set; } [DisplayName("Region")] [StringLength(15)] public string Region { get; set; } [DisplayName("Postal Code")] [StringLength(10)] public string PostalCode { get; set; } [DisplayName("Country")] [StringLength(15)] public string Country { get; set; } [DisplayName("Phone")] [StringLength(24)] public string Phone { get; set; } [DisplayName("Fax")] [StringLength(24)] public string Fax { get; set; } } } The gen’d class can be used from your project by creating a partial class with the entity name and setting the MetadataType attribute.namespace MyProject.Models{ [MetadataType(typeof(CustomerAutoMetadata))] public partial class Customer { }} You can also copy the code in the metadata class generated and create your own ViewModel class. Note that the template is super basic and does not take into account complex properties. I have tested it with the Northwind database. This is a work in progress. Feel free to modify the template to suite your requirements. Standard disclaimer follows: Use At Your Own Risk, Works on my machine running VS 2010 RTM/ASP.NET MVC 2 AutoMetaData.zip Mr. Incredible: Of course I have a secret identity.

How do I get the displayname of the logged in user in EWS?

- by tig

Exchange Autodiscovery will give me the user's Display Name via the UserSettingName.UserDisplayName property. However, in cases where autodiscovery fails and connection needs to be done manually I can't figure out how to get the DisplayName. I tried this, but I just get the users' email address: _service = new ExchangeService(); _service.Credentials = new System.Net.NetworkCredential(exchangeSettings.EmailAddress, exchangeSettings.Password); _service.Url = new Uri(exchangeSettings.ExternalEwsUrl); NameResolutionCollection resolvedNames = _service.ResolveName(exchangeSettings.EmailAddress); exchangeSettings.UserDisplayName = resolvedNames.First().Mailbox.Name; Thanks

PowerShell Script To Find Where SharePoint 2007 Features Are Activated

- by Brian T. Jackett

Recently I posted a script to find where SharePoint 2010 Features Are Activated. I built the original version to use SharePoint 2010 PowerShell commandlets as that saved me a number of steps for filtering and gathering features at each level. If there was ever demand for a 2007 version I could modify the script to handle that by using the object model instead of commandlets. Just the other week a fellow SharePoint PFE Jason Gallicchio had a customer asking about a version for SharePoint 2007. With a little bit of work I was able to convert the script to work against SharePoint 2007. Solution Below is the converted script that works against a SharePoint 2007 farm. Note: There appears to be a bug with the 2007 version that does not give accurate results against a SharePoint 2010 farm. I ran the 2007 version against a 2010 farm and got fewer results than my 2010 version of the script. Discussing with some fellow PFEs I think the discrepancy may be due to sandboxed features, a new concept in SharePoint 2010. I have not had enough time to test or confirm. For the time being only use the 2007 version script against SharePoint 2007 farms and the 2010 version against SharePoint 2010 farms. Note: This script is not optimized for medium to large farms. In my testing it took 1-3 minutes to recurse through my demo environment. This script is provided as-is with no warranty. Run this in a smaller dev / test environment first. 001 002 003 004 005 006 007 008 009 010 011 012 013 014 015 016 017 018 019 020 021 022 023 024 025 026 027 028 029 030 031 032 033 034 035 036 037 038 039 040 041 042 043 044 045 046 047 048 049 050 051 052 053 054 055 056 057 058 059 060 061 062 063 064 065 066 067 068 069 070 function Get-SPFeatureActivated { # see full script for help info, removed for formatting [CmdletBinding()] param( [Parameter(position = 1, valueFromPipeline=$true)] [string] $Identity )#end param Begin { # load SharePoint assembly to access object model [void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") # declare empty array to hold results.

As always I appreciate any feedback on scripts. If anyone is motivated to run this 2007 version script against a SharePoint 2010 to see if they find any differences in number of features reported versus what they get with the 2010 version script I’d love to hear from you. -Frog Out

How to "DRY up" C# attributes in Models and ViewModels?

- by DanM

This question was inspired by my struggles with ASP.NET MVC, but I think it applies to other situations as well. Let's say I have an ORM-generated Model and two ViewModels (one for a "details" view and one for an "edit" view): Model public class FooModel // ORM generated { public int Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string EmailAddress { get; set; } public int Age { get; set; } public int CategoryId { get; set; } } Display ViewModel public class FooDisplayViewModel // use for "details" view { [DisplayName("ID Number")] public int Id { get; set; } [DisplayName("First Name")] public string FirstName { get; set; } [DisplayName("Last Name")] public string LastName { get; set; } [DisplayName("Email Address")] [DataType("EmailAddress")] public string EmailAddress { get; set; } public int Age { get; set; } [DisplayName("Category")] public string CategoryName { get; set; } } Edit ViewModel public class FooEditViewModel // use for "edit" view { [DisplayName("First Name")] // not DRY public string FirstName { get; set; } [DisplayName("Last Name")] // not DRY public string LastName { get; set; } [DisplayName("Email Address")] // not DRY [DataType("EmailAddress")] // not DRY public string EmailAddress { get; set; } public int Age { get; set; } [DisplayName("Category")] // not DRY public SelectList Categories { get; set; } } Note that the attributes on the ViewModels are not DRY--a lot of information is repeated. Now imagine this scenario multiplied by 10 or 100, and you can see that it can quickly become quite tedious and error prone to ensure consistency across ViewModels (and therefore across Views). How can I "DRY up" this code? Before you answer, "Just put all the attributes on FooModel," I've tried that, but it didn't work because I need to keep my ViewModels "flat". In other words, I can't just compose each ViewModel with a Model--I need my ViewModel to have only the properties (and attributes) that should be consumed by the View, and the View can't burrow into sub-properties to get at the values. Update LukLed's answer suggests using inheritance. This definitely reduces the amount of non-DRY code, but it doesn't eliminate it. Note that, in my example above, the DisplayName attribute for the Category property would need to be written twice because the data type of the property is different between the display and edit ViewModels. This isn't going to be a big deal on a small scale, but as the size and complexity of a project scales up (imagine a lot more properties, more attributes per property, more views per model), there is still the potentially for "repeating yourself" a fair amount. Perhaps I'm taking DRY too far here, but I'd still rather have all my "friendly names", data types, validation rules, etc. typed out only once.

Bind a SL4 TreeView to an IGrouping using Caliburn

- by illdev

I am just starting in the SL world and am trying to use the Caliburn NavigationShell as my starting point. I converted the solution to SL4 and use Caliburn from the trunk . To create the basic navigation, I am a bit unsure (well, quite), how I can display the original StackPanel of Buttons as a collapsible Treeview. I changed ITaskBarItem to own a simple GroupName property public interface ITaskBarItem : IEntryPoint { BitmapImage Icon { get; } string DisplayName { get; } string GroupName { get;} } then, I expose this in ShellViewModel to the View: public IEnumerable<IGrouping<string, ITaskBarItem>> TaskBarItems { get { return _taskBarItems.GroupBy(t => t.GroupName); } } How can I do the xaml markup so that I get a simple hierarchy? How can I bind Actions with out the use of Buttons? GroupName DisplayName DisplayName DisplayName GroupName DisplayName DisplayName DisplayName ... Mind, this is MVVM, so I am not going to use code behind or events to do that...

Distinctly LINQ – Getting a Distinct List of Objects

- by David Totzke

Let’s say that you have a list of objects that contains duplicate items and you want to extract a subset of distinct items. This is pretty straight forward in the trivial case where the duplicate objects are considered the same such as in the following example: List<int> ages = new List<int> { 21, 46, 46, 55, 17, 21, 55, 55 }; IEnumerable<int> distinctAges = ages.Distinct(); Console.WriteLine("Distinct ages:"); foreach (int age in distinctAges) { Console.WriteLine(age); } /* This code produces the following output: Distinct ages: 21 46 55 17 */ What if you are working with reference types instead? Imagine a list of search results where items in the results, while unique in and of themselves, also point to a parent. We’d like to be able to select a bunch of items in the list but then see only a distinct list of parents. Distinct isn’t going to help us much on its own as all of the items are distinct already. Perhaps we can create a class with just the information we are interested in like the Id and Name of the parents. public class SelectedItem { public int ItemID { get; set; } public string DisplayName { get; set; } } We can then use LINQ to populate a list containing objects with just the information we are interested in and then get rid of the duplicates. IEnumerable<SelectedItem> list = (from item in ResultView.SelectedRows.OfType<Contract.ReceiptSelectResults>() select new SelectedItem { ItemID = item.ParentId, DisplayName = item.ParentName }) .Distinct(); Most of you will have guessed that this didn’t work. Even though some of our objects are now duplicates, because we are working with reference types, it doesn’t matter that their properties are the same, they’re still considered unique. What we need is a way to define equality for the Distinct() extension method. IEqualityComparer<T> Looking at the Distinct method we see that there is an overload that accepts an IEqualityComparer<T>. We can simply create a class that implements this interface and that allows us to define equality for our SelectedItem class. public class SelectedItemComparer : IEqualityComparer<SelectedItem> { public new bool Equals(SelectedItem abc, SelectedItem def) { return abc.ItemID == def.ItemID && abc.DisplayName == def.DisplayName; } public int GetHashCode(SelectedItem obj) { string code = obj.DisplayName + obj.ItemID.ToString(); return code.GetHashCode(); } } In the Equals method we simply do whatever comparisons are necessary to determine equality and then return true or false. Take note of the implementation of the GetHashCode method. GetHashCode must return the same value for two different objects if our Equals method says they are equal. Get this wrong and your comparer won’t work . Even though the Equals method returns true, mismatched hash codes will cause the comparison to fail. For our example, we simply build a string from the properties of the object and then call GetHashCode() on that. Now all we have to do is pass an instance of our IEqualitlyComarer<T> to Distinct and all will be well: IEnumerable<SelectedItem> list = (from item in ResultView.SelectedRows.OfType<Contract.ReceiptSelectResults>() select new SelectedItem { ItemID = item.dahfkp, DisplayName = item.document_code }) .Distinct(new SelectedItemComparer()); Enjoy.

UIButton in UITableViewCell events not working

- by Tristan

I see this problem all over the net, and none of the solutions listed work for me! I have added UIButton to a UITableViewCell in IB. I have assigned a custom UITableViewCell class to the UITableViewCell. My custom UITableViewCell class has an IBAction that im connecting to the Touch Up Inside event (I have tried other events they all don't work) but the IBAction function is never called! There is nothing else in the UITableViewCell, I have added the UIButton directly into the Content View. And everything has user interaction enabled! It is as simple as that I have nothing complex going on! What is is about a UITableViewCell that stops buttons working? EDIT: By request the code where I initialize my UITableViewCells the custom class is called DownloadCell - (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"DownloadCell"; DownloadCell *cell = (DownloadCell *)[aTableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { UIViewController * cellController = [[UIViewController alloc] initWithNibName:@"DownloadCell" bundle:nil]; cell = (DownloadCell *)cellController.view; [cellController release]; } SoundLibrarianIPhoneAppDelegate * del = (SoundLibrarianIPhoneAppDelegate *)[UIApplication sharedApplication].delegate; DownloadQueue * dq = del.downloadQueue; DownloadJob * job = [dq getDownloadJob: indexPath.row]; [job setDelegate:self]; SoundInfo * info = [job sound]; NSArray * seperated = [info.fileName componentsSeparatedByString: @"."]; NSString * displayName = [seperated objectAtIndex:0]; displayName = [displayName stringByReplacingOccurrencesOfString:@"_" withString:@" "]; displayName = [displayName capitalizedString]; [cell.titleLabel setText: displayName]; cell.progressBar.progress = job.percentCompleted; [cell.progressLabel setText: [job getProgessText]]; cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.userInteractionEnabled = YES; [cell setDelegate:self]; return cell; }

ASP.NET MVC localization DisplayNameAttribute alternatives: a better way

- by Brian Schroer

In my last post, I talked bout creating a custom class inheriting from System.ComponentModel.DisplayNameAttribute to retrieve display names from resource files: [LocalizedDisplayName("RememberMe")] public bool RememberMe { get; set; } That’s a lot of work to put an attribute on all of my model properties though. It would be nice if I could intercept the ASP.NET MVC code that analyzes the model metadata to retrieve display names to make it automatically get localized text from my resource files. That way, I could just set up resource file entries where the keys are the property names, and not have to put attributes on all of my properties. That’s done by creating a custom class inheriting from System.Web.Mvc.DataAnnotationsModelMetadataProvider: 1: public class LocalizedDataAnnotationsModelMetadataProvider : 2: DataAnnotationsModelMetadataProvider 3: { 4: protected override ModelMetadata CreateMetadata( 5: IEnumerable<Attribute> attributes, 6: Type containerType, 7: Func<object> modelAccessor, 8: Type modelType, 9: string propertyName) 10: { 11: var meta = base.CreateMetadata 12: (attributes, containerType, modelAccessor, modelType, propertyName); 13: 14: if (string.IsNullOrEmpty(propertyName)) 15: return meta; 16: 17: if (meta.DisplayName == null) 18: GetLocalizedDisplayName(meta, propertyName); 19: 20: if (string.IsNullOrEmpty(meta.DisplayName)) 21: meta.DisplayName = string.Format("[[{0}]]", propertyName); 22: 23: return meta; 24: } 25: 26: private static void GetLocalizedDisplayName(ModelMetadata meta, string propertyName) 27: { 28: ResourceManager resourceManager = MyResource.ResourceManager; 29: CultureInfo culture = Thread.CurrentThread.CurrentUICulture; 30: 31: meta.DisplayName = resourceManager.GetString(propertyName, culture); 32: } 33: } Line 11 calls the base CreateMetadata method. Line 17 checks whether the metadata DisplayName property has already been populated by a DisplayNameAttribute (or my LocalizedDisplayNameAttribute). If so, it respects that and doesn’t use my custom localized text lookup. The GetLocalizedDisplayName method checks for the property name as a resource file key. If found, it uses the localized text from the resource files. If the key is not found in the resource file, as with my LocalizedDisplayNameAttribute, I return a formatted string containing the property name (e.g. “[[RememberMe]]”) so I can tell by looking at my web pages which resource keys I haven’t defined yet. It’s hooked up with this code in the Application_Start method of Global.asax: ModelMetadataProviders.Current = new LocalizedDataAnnotationsModelMetadataProvider();

SHAREPOINT: Custom Field type property storage defined for custom field

- by Eric Rockenbach

ok here is a great question. I have a set of generic custom fields that are highly configurable from an end user perspective and the configuration is getting overbearing as there are nearly 100 plus items each custom field allows you to perform in the areas of Server/Client Validation, Server/Client Events/Actions, Server/Client Bindings parent/child, display properties for form/control, etc, etc. Right now I'm storing most of these values as "Text" in my field xml for my propertyschema. I'm very familiar with the multi column value, but this is not a complex custom type in sense it's an array. I also considered creating serilzable objects and stuffing them into the text field and then pulling out and de-serilizing them when editing through the field editor or acting on the rules through the custom spfield. So I'm trying to take the following for example <PropertySchema> <Fields> <Field Name="EntityColumnName" Hidden="TRUE" DisplayName="EntityColumnName" MaxLength="500" DisplaySize="200" Type="Text"> <default></default> </Field> <Field Name="EntityColumnParentPK" Hidden="TRUE" DisplayName="EntityColumnParentPK" MaxLength="500" DisplaySize="200" Type="Text"> <default></default> </Field> <Field Name="EntityColumnValueName" Hidden="TRUE" DisplayName="EntityColumnValueName" MaxLength="500" DisplaySize="200" Type="Text"> <default></default> </Field> <Field Name="EntityListName" Hidden="TRUE" DisplayName="EntityListName" MaxLength="500" DisplaySize="200" Type="Text"> <default></default> </Field> <Field Name="EntitySiteUrl" Hidden="TRUE" DisplayName="EntitySiteUrl" MaxLength="500" DisplaySize="200" Type="Text"> <default></default> </Field> </Fields> <PropertySchema> And turn it into this... <PropertySchema> <Fields> <Field Name="ServerValidationRules" Hidden="TRUE" DisplayName="ServerValidationRules" Type="ServerValidationRulesType"> <default></default> </Field> </Fields> <PropertySchema> Ideas?????

Bind listbox in WPF with grouping

- by Michael Stoll

Hi, I've got a collection of ViewModels and want to bind a ListBox to them. Doing some investigation I found this. So my ViewModel look like this (Pseudo Code) interface IItemViewModel { string DisplayName { get; } } class AViewModel : IItemViewModel { string DisplayName { return "foo"; } } class BViewModel : IItemViewModel { string DisplayName { return "foo"; } } class ParentViewModel { IEnumerable<IItemViewModel> Items { get { return new IItemViewModel[] { new AItemViewModel(), new BItemViewModel() } } } } class GroupViewModel { static readonly GroupViewModel GroupA = new GroupViewModel(0); static readonly GroupViewModel GroupB = new GroupViewModel(1); int GroupIndex; GroupViewModel(int groupIndex) { this.GroupIndex = groupIndex; } string DisplayName { get { return "This is group " + GroupIndex.ToString(); } } } class ItemGroupTypeConverter : IValueConverter { object Convert(object value, Type targetType, object parameter, CultureInfo culture) { if (value is AItemViewModel) return GroupViewModel.GroupA; else return GroupViewModel.GroupB; } } And this XAML <UserControl.Resources> <vm:ItemsGroupTypeConverter x:Key="ItemsGroupTypeConverter "/> <CollectionViewSource x:Key="GroupedItems" Source="{Binding Items}"> <CollectionViewSource.GroupDescriptions> <PropertyGroupDescription Converter="{StaticResource ItemsGroupTypeConverter }"/> </CollectionViewSource.GroupDescriptions> </CollectionViewSource> </UserControl.Resources> <ListBox ItemsSource="{Binding Source={StaticResource GroupedItems}}"> <ListBox.GroupStyle> <GroupStyle> <GroupStyle.HeaderTemplate> <DataTemplate> <TextBlock Text="{Binding DisplayName}" FontWeight="bold" /> </DataTemplate> </GroupStyle.HeaderTemplate> </GroupStyle> </ListBox.GroupStyle> <ListBox.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding DisplayName}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> This works somehow, exept of the fact that the binding of the HeaderTemplate does not work. Anyhow I'd prefer omitting the TypeConverter and the CollectionViewSource. Isn't there a way to use a property of the ViewModel for Grouping? I know that in this sample scenario it would be easy to replace the GroupViewModel with a string an have it working, but that's not an option. So how can I bind the HeaderTemplate to the GroupViewModel?

Threadsafe binding with DispatcherObject.CheckAccess()

- by maffe

Hi, according to this, I can achieve threadsafety with large overhead. I wrote the following class and use it. It works fine. public abstract class BindingBase : DispatcherObject, INotifyPropertyChanged, INotifyPropertyChanging { private string _displayName; private const string NameDisplayName = "DisplayName"; /// /// The display name for the gui element which bound this instance. It can be used for localization. /// public string DisplayName { get { return _displayName; } set { NotifyPropertyChanging(NameDisplayName); _displayName = value; NotifyPropertyChanged(NameDisplayName); } } protected BindingBase() {} protected BindingBase(string displayName) { DisplayName = displayName; } public event PropertyChangedEventHandler PropertyChanged; public event PropertyChangingEventHandler PropertyChanging; protected void NotifyPropertyChanged(string name) { if (PropertyChanged == null) return; if (CheckAccess()) PropertyChanged.Invoke(this, new PropertyChangedEventArgs(name)); else Dispatcher.BeginInvoke(DispatcherPriority.Normal, (Action) (() = NotifyPropertyChanged(name))); } protected void NotifyPropertyChanging(string name) { if (PropertyChanging == null) return; if (CheckAccess()) PropertyChanging.Invoke(this, new PropertyChangingEventArgs(name)); else Dispatcher.BeginInvoke(DispatcherPriority.Normal, (Action) (() = NotifyPropertyChanging(name))); } } So is there a reason, why I've never found something like that? Are there any issues I should be aware off? Regards

Creating a service that takes parameters with WMI

- by Johan_B

I want to create a service that takes some parameters. How do I do this with WMI? In the commandline, it was sc create ServiceName binPath= ""C:\Path\Service.exe\" /Service somefile1.xml somefile2.xml" start=auto DisplayName="DisplayName" I have tried to use ManagementBaseObject inParams = managementClass.GetMethodParameters("create"); inParams["CommandLine"] = ""C:\Path\Service.exe\" somefile1.xml somefile2.xml" inParams["StartMode"] = StartMode.Auto; inParasm["DisplayName"] = "displayName"; but I do not know how to pass the two xml files? Any help will be greatly appreciated. Thanks! JB

Error data: line 2 column 1 when using pycurl with gzip stream

- by Sagar Hatekar

Thanks for reading. Background: I am trying to read a streaming API feed that returns data in JSON format, and then storing this data to a pymongo collection. The streaming API requires a "Accept-Encoding" : "Gzip" header. What's happening: Code fails on json.loads and outputs - Extra data: line 2 column 1 - line 4 column 1 (char 1891 - 5597) (Refer Error Log below) This does NOT happen while parsing every JSON object - it happens at random. My guess is I am encountering some weird JSON object after every "x" proper JSON objects. I did reference how to use pycurl if requested data is sometimes gzipped, sometimes not? and Encoding error while deserializing a json object from Google but so far have been unsuccessful at resolving this error. Could someone please help me out here? Error Log: Note: The raw dump of the JSON object below is basically using the repr() method.

Annotation Processor for Superclass Sensitive Actions

- by Geertjan

Someone creating superclass sensitive actions should need to specify only the following things: The condition under which the popup menu item should be available, i.e., the condition under which the action is relevant. And, for superclass sensitive actions, the condition is the name of a superclass. I.e., if I'm creating an action that should only be invokable if the class implements "org.openide.windows.TopComponent", then that fully qualified name is the condition. The position in the list of Java class popup menus where the new menu item should be found, relative to the existing menu items. The display name. The path to the action folder where the new action is registered in the Central Registry. The code that should be executed when the action is invoked. In other words, the code for the enablement (which, in this case, means the visibility of the popup menu item when you right-click on the Java class) should be handled generically, under the hood, and not every time all over again in each action that needs this special kind of enablement. So, here's the usage of my newly created @SuperclassBasedActionAnnotation, where you should note that the DataObject must be in the Lookup, since the action will only be available to be invoked when you right-click on a Java source file (i.e., text/x-java) in an explorer view: import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import org.netbeans.sbas.annotations.SuperclassBasedActionAnnotation; import org.openide.awt.StatusDisplayer; import org.openide.loaders.DataObject; import org.openide.util.NbBundle; import org.openide.util.Utilities; @SuperclassBasedActionAnnotation( position=30, displayName="#CTL_BrandTopComponentAction", path="File", type="org.openide.windows.TopComponent") @NbBundle.Messages("CTL_BrandTopComponentAction=Brand") public class BrandTopComponentAction implements ActionListener { private final DataObject context; public BrandTopComponentAction() { context = Utilities.actionsGlobalContext().lookup(DataObject.class); } @Override public void actionPerformed(ActionEvent ev) { String message = context.getPrimaryFile().getPath(); StatusDisplayer.getDefault().setStatusText(message); } } That implies I've created (in a separate module to where it is used) a new annotation. Here's the definition: package org.netbeans.sbas.annotations; import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; @Retention(RetentionPolicy.SOURCE) @Target(ElementType.TYPE) public @interface SuperclassBasedActionAnnotation { String type(); String path(); int position(); String displayName(); } And here's the processor: package org.netbeans.sbas.annotations; import java.util.Set; import javax.annotation.processing.Processor; import javax.annotation.processing.RoundEnvironment; import javax.annotation.processing.SupportedAnnotationTypes; import javax.annotation.processing.SupportedSourceVersion; import javax.lang.model.SourceVersion; import javax.lang.model.element.Element; import javax.lang.model.element.TypeElement; import javax.lang.model.util.Elements; import org.openide.filesystems.annotations.LayerBuilder.File; import org.openide.filesystems.annotations.LayerGeneratingProcessor; import org.openide.filesystems.annotations.LayerGenerationException; import org.openide.util.lookup.ServiceProvider; @ServiceProvider(service = Processor.class) @SupportedAnnotationTypes("org.netbeans.sbas.annotations.SuperclassBasedActionAnnotation") @SupportedSourceVersion(SourceVersion.RELEASE_6) public class SuperclassBasedActionProcessor extends LayerGeneratingProcessor { @Override protected boolean handleProcess(Set annotations, RoundEnvironment roundEnv) throws LayerGenerationException { Elements elements = processingEnv.getElementUtils(); for (Element e : roundEnv.getElementsAnnotatedWith(SuperclassBasedActionAnnotation.class)) { TypeElement clazz = (TypeElement) e; SuperclassBasedActionAnnotation mpm = clazz.getAnnotation(SuperclassBasedActionAnnotation.class); String teName = elements.getBinaryName(clazz).toString(); String originalFile = "Actions/" + mpm.path() + "/" + teName.replace('.', '-') + ".instance"; File actionFile = layer(e).file( originalFile). bundlevalue("displayName", mpm.displayName()). methodvalue("instanceCreate", "org.netbeans.sbas.annotations.SuperclassSensitiveAction", "create"). stringvalue("type", mpm.type()). newvalue("delegate", teName); actionFile.write(); File javaPopupFile = layer(e).file( "Loaders/text/x-java/Actions/" + teName.replace('.', '-') + ".shadow"). stringvalue("originalFile", originalFile). intvalue("position", mpm.position()); javaPopupFile.write(); } return true; } } The "SuperclassSensitiveAction" referred to in the code above is unchanged from how I had it in yesterday's blog entry. When I build the module containing two action listeners that use my new annotation, the generated layer file looks as follows, which is identical to the layer file entries I hard coded yesterday: <folder name="Actions"> <folder name="File"> <file name="org-netbeans-sbas-impl-ActionListenerSensitiveAction.instance"> <attr name="displayName" stringvalue="Process Action Listener"/> <attr methodvalue="org.netbeans.sbas.annotations.SuperclassSensitiveAction.create" name="instanceCreate"/> <attr name="type" stringvalue="java.awt.event.ActionListener"/> <attr name="delegate" newvalue="org.netbeans.sbas.impl.ActionListenerSensitiveAction"/> </file> <file name="org-netbeans-sbas-impl-BrandTopComponentAction.instance"> <attr bundlevalue="org.netbeans.sbas.impl.Bundle#CTL_BrandTopComponentAction" name="displayName"/> <attr methodvalue="org.netbeans.sbas.annotations.SuperclassSensitiveAction.create" name="instanceCreate"/> <attr name="type" stringvalue="org.openide.windows.TopComponent"/> <attr name="delegate" newvalue="org.netbeans.sbas.impl.BrandTopComponentAction"/> </file> </folder> </folder> <folder name="Loaders"> <folder name="text"> <folder name="x-java"> <folder name="Actions"> <file name="org-netbeans-sbas-impl-ActionListenerSensitiveAction.shadow"> <attr name="originalFile" stringvalue="Actions/File/org-netbeans-sbas-impl-ActionListenerSensitiveAction.instance"/> <attr intvalue="10" name="position"/> </file> <file name="org-netbeans-sbas-impl-BrandTopComponentAction.shadow"> <attr name="originalFile" stringvalue="Actions/File/org-netbeans-sbas-impl-BrandTopComponentAction.instance"/> <attr intvalue="30" name="position"/> </file> </folder> </folder> </folder> </folder>

Scheduling runtime-specified Activity in Workflow 4 RC

- by johnny g

Hi, so I have this requirement to kick off Activities provided to me at run-time. To facilitate this, I have set up a WorkflowService that receives Activities as Xaml, hydrates them, and kicks them off. Sounds simple enough ... ... this is my WorkflowService in Xaml <Activity x:Class="Workflow.Services.WorkflowService.WorkflowService" ... xmlns:local1="clr-namespace:Workflow.Activities" > <Sequence sap:VirtualizedContainerService.HintSize="277,272"> <Sequence.Variables> <Variable x:TypeArguments="local:Workflow" Name="Workflow" /> </Sequence.Variables> <sap:WorkflowViewStateService.ViewState> <scg3:Dictionary x:TypeArguments="x:String, x:Object"> <x:Boolean x:Key="IsExpanded">True</x:Boolean> </scg3:Dictionary> </sap:WorkflowViewStateService.ViewState> <p:Receive CanCreateInstance="True" DisplayName="ReceiveSubmitWorkflow" sap:VirtualizedContainerService.HintSize="255,86" OperationName="SubmitWorkflow" ServiceContractName="IWorkflowService"> <p:ReceiveParametersContent> <OutArgument x:TypeArguments="local:Workflow" x:Key="workflow">[Workflow]</OutArgument> </p:ReceiveParametersContent> </p:Receive> <local1:InvokeActivity Activity="[ActivityXamlServices.Load(New System.IO.StringReader(Workflow.Xaml))]" sap:VirtualizedContainerService.HintSize="255,22" /> </Sequence> </Activity> ... which, except for repetitive use of "Workflow" is pretty straight forward. In fact, it's just a Sequence with a Receive and [currently] a custom Activity called InvokeActivity. Get to that in a bit. Receive Activity accepts a custom type, [DataContract] public class Workflow { [DataMember] public string Xaml { get; set; } } which contains a string whose contents are to be interpreted as Xaml. You can see the VB expression that then converts this Xaml to an Activity and passes it on. Now this second bit, the custom InvokeActivity is where I have questions. First question: 1) given an arbitrary task, provided at runtime [as described above] is it possible to kick off this Activity using Activities that ship with WF4RC, out of the box? I'm fairly new, and thought I did a good job going through the API and existing documentation, but may as well ask :) Second: 2) my first attempt at implementing a custom InvokeActivity looked like this public sealed class InvokeActivity : NativeActivity { private static readonly ILog _log = LogManager.GetLogger (typeof (InvokeActivity)); public InArgument<Activity> Activity { get; set; } public InvokeActivity () { _log.DebugFormat ("Instantiated."); } protected override void Execute (NativeActivityContext context) { Activity activity = Activity.Get (context); _log.DebugFormat ("Scheduling activity [{0}]...", activity.DisplayName); // throws exception to lack of metadata! :( ActivityInstance instance = context.ScheduleActivity (activity, OnComplete, OnFault); _log.DebugFormat ( "Scheduled activity [{0}] with instance id [{1}].", activity.DisplayName, instance.Id); } protected override void CacheMetadata (NativeActivityMetadata metadata) { // how does one add InArgument<T> to metadata? not easily // is my first guess base.CacheMetadata (metadata); } // private methods private void OnComplete ( NativeActivityContext context, ActivityInstance instance) { _log.DebugFormat ( "Scheduled activity [{0}] with instance id [{1}] has [{2}].", instance.Activity.DisplayName, instance.Id, instance.State); } private void OnFault ( NativeActivityFaultContext context, Exception exception, ActivityInstance instance) { _log.ErrorFormat ( @"Scheduled activity [{0}] with instance id [{1}] has faulted in state [{2}] {3}", instance.Activity.DisplayName, instance.Id, instance.State, exception.ToStringFullStackTrace ()); } } Which attempts to schedule the specified Activity within the current context. Unfortunately, however, this fails. When I attempt to schedule said Activity, the runtime returns with the following exception The provided activity was not part of this workflow definition when its metadata was being processed. The problematic activity named 'DynamicActivity' was provided by the activity named 'InvokeActivity'. Right, so the "dynamic" Activity provided at runtime is not a member of InvokeActivitys metadata. Googled and came across this. Couldn't sort out how to specify an InArgument<Activity> to metadata cache, so my second question is, naturally, how does one address this issue? Is it ill advised to use context.ScheduleActivity (...) in this manner? Third and final, 3) I have settled on this [simpler] solution for the time being, public sealed class InvokeActivity : NativeActivity { private static readonly ILog _log = LogManager.GetLogger (typeof (InvokeActivity)); public InArgument<Activity> Activity { get; set; } public InvokeActivity () { _log.DebugFormat ("Instantiated."); } protected override void Execute (NativeActivityContext context) { Activity activity = Activity.Get (context); _log.DebugFormat ("Invoking activity [{0}] ...", activity.DisplayName); // synchronous execution ... a little less than ideal, this // seems heavy handed, and not entirely semantic-equivalent // to what i want. i really want to invoke this runtime // activity as if it were one of my own, not a separate // process - wrong mentality? WorkflowInvoker.Invoke (activity); _log.DebugFormat ("Invoked activity [{0}].", activity.DisplayName); } } Which simply invokes specified task synchronously within its own runtime instance thingy [use of WF4 vernacular is certainly questionable]. Eventually, I would like to tap into WF's tracking and possibly persistance facilities. So my third and final question is, in terms of what I would like to do [ie kick off arbitrary workflows inbound from client applications] is this the preferred method? Alright, thanks in advance for your time and consideration :)

Organising levels / rooms in a MUD-style text based world

- by Polynomial

I'm thinking of writing a small text-based adventure game, but I'm not particularly sure how I should design the world from a technical standpoint. My first thought is to do it in XML, designed something like the following. Apologies for the huge pile of XML, but I felt it important to fully explain what I'm doing. <level> <start>  <room>Kitchen</room> <inventory></inventory> </start> <rooms> <room> <name>Kitchen</name> <description>A small kitchen that looks like it hasn't been used in a while. It has a table in the middle, and there are some cupboards. There is a door to the north, which leads to the garden.</description>  <objects> <object>Cupboards</object> <object>Knife</object> <object>Batteries</object> </objects> </room> <room> <name>Garden</name> <description>The garden is wild and full of prickly bushes. To the north there is a path, which leads into the trees. To the south there is a house.</description> <objects> </objects> </room> <room> <name>Woods</name> <description>The woods are quite dark, with little light bleeding in from the garden. It is eerily quiet.</description> <objects> <object>Trees01</object> </objects> </room> </rooms> <doors>  <door> <type>door</type> <direction>N</direction> <from>Kitchen</from> <to>Garden</to> </door> <door> <type>path</type> <direction>N</direction> <from>Garden</type> <to>Woods</type> </door> </doors> <variables>  <variable name="cupboard_open">0</variable> </variables> <objects>  <object> <name>Trees01</name> <displayName>Trees</displayName> <actions>  <action> <command>EXAMINE</command> <message>The trees are tall and thick. There aren't any low branches, so it'd be difficult to climb them.</message> </action> </actions> </object> <object> <name>Cupboards</name> <displayName>Cupboards</displayName> <actions> <action>  <requirements>  <require operation="equal" value="1">cupboard_open</require> </requirements> <command>EXAMINE</command>  <failMessage>The cupboard is closed.</failMessage> <message>The cupboard contains some batteires.</message> </action> <action> <requirements> <require operation="equal" value="0">cupboard_open</require> </requirements> <command>OPEN</command> <failMessage>The cupboard is already open.</failMessage> <message>You open the cupboard. It contains some batteries.</message>  <assigns> <assign operation="set" value="1">cupboard_open</assign> </assigns> </action> <action> <requirements> <require operation="equal" value="1">cupboard_open</require> </requirements> <command>CLOSE</command> <failMessage>The cupboard is already closed.</failMessage> <message>You closed the cupboard./message> <assigns> <assign operation="set" value="0">cupboard_open</assign> </assigns> </action> </actions> </object> <object> <name>Batteries</name> <displayName>Batteries</displayName>  <inventory>1</inventory> <actions> <action> <requirements> <require operation="equal" value="1">cupboard_open</require> </requirements> <command>GET</command>  <message>You picked up the batteries.</message> </action> </actions> </object> </objects> </level> Obviously there'd need to be more to it than this. Interaction with people and enemies as well as death and completion are necessary additions. Since the XML is quite difficult to work with, I'd probably create some sort of world editor. I'd like to know if this method has any downfalls, and if there's a "better" or more standard way of doing it.
