• What are the common compliance standards for software products?

  - by Jay

  This is a very generic question about software products. I would like to know what compliance standards are applicable to any software product. I know that question gives away nothing. So, here is an example to what I am referring to. CiSecurity Security Certification/Compliance lists out products ceritified by them to be compliant to the standards published at their website, i.e, cisecurity.org. Compliance could be as simple as answering a questionnaire for your product and approved by a thirdparty like cisecurity or it could apply to your whole organization, for instance, PCI-DSS compliance. I would be very interested in knowing the standards that products you know/designed/created, comply to. To give you the context behind this question: I am the developer of a data-masking tool. The said tool helps mask onscreen html text in a banking web application using filters. So, for instance, if the bank application lists out user information with ssn, my product when integrated with the banking product, automatically identifies ssn pattern and masks it into a pre-defined format.So, I have my product marketing team wanting more buzz words like compliance to be able to sell it to more banking clients. Hence, understanding "compliances that apply to products" is a key research item for me at this point. By which I meant, security compliances. Appreciate all your help and suggestions.

• Hashing the state of a complex object in .NET

  - by Jan

  Some background information: I am working on a C#/WPF application, which basically is about creating, editing, saving and loading some data model. The data model contains of a hierarchy of various objects. There is a "root" object of class A, which has a list of objects of class B, which each has a list of objects of class C, etc. Around 30 classes involved in total. Now my problem is that I want to prompt the user with the usual "you have unsaved changes, save?" dialog, if he tries to exit the program. But how do I know if the data in current loaded model is actually changed? There is of course ways to solve this, like e.g. reloading the model from file and compare against the one in memory value by value or make every UI control set a flag indicating the model has been changed. Now instead, I want to create a hash value based on the model state on load and generate a new value when the user tries to exit, and compare those two. Now the question: So inspired of that, I was wondering if there exist some way to generate a hash value from the (value)state of some arbitrary complex object? Preferably in a generic way, e.g. no need to apply attributes to each involved class/field. One idea could be to use some of .NET's serialization functionality (assuming it will work out-of-the-box in this case) and apply a hash function to the content of the resulting file. However, I guess there exist some more suitable approach. Thanks in advance.

• how to release object from thid party dll?

  - by Mohamed

  hi all, i'm developing a program to convert RTF to html i'm using the DLLs found here http://www.codeproject.com/KB/recipes/RtfConverter.aspx?fid=1458864&df=90&mpp=25&noise=3&sort=Position&view=Quick&select=3427424&fr=1#xx0xx this dll saves a jpg file from html to a specific folder, when i run the program, it cinverts the rtf for the first time and saves the images to the folder perfectly but when i try to convert it again i hace this error "error a generic error occured in GDI+" i think this dll use SaveImage method and to avoid this you must release the Image object you created but i can't modify the DLL, is there is any way to release the object i've created from this dll? this is my code RtfVisualImageAdapter imageAdapter = new RtfVisualImageAdapter( @Application.StartupPath + "\\Program Data\\temp\\{0}{1}", System.Drawing.Imaging.ImageFormat.Jpeg); RtfImageConvertSettings imageConvertSettings = new RtfImageConvertSettings(imageAdapter); RtfImageConverter imageConverter = new RtfImageConverter(imageConvertSettings); try { IRtfDocument rtfDocument = RtfInterpreterTool.BuildDoc( ConversionText, imageConverter); RtfHtmlConverter htmlConverter = new RtfHtmlConverter(rtfDocument); htmlConverter.Settings.ConvertVisualHyperlinks = true; htmlConverter.Settings.UseNonBreakingSpaces = true; this.richTextBoxPrintCtrl2.Text = htmlConverter.Convert(); } catch (Exception exception) { MessageBox.Show(this, "Error " + exception.Message, this.Text, MessageBoxButtons.OK, MessageBoxIcon.Error); }

• Writing to the DataContext

  - by user738383

  I have a function. This function takes an IEnumerable<Customer> (Customer being an entity). What the function needs to do is tell the DataContext (which has a collection of Customers as a property) that its Customers property needs to be overwritten with this passed in IEnumerable<Customer>. I can't use assignment because DomainContext.Customers cannot be assigned to, as it is read only. I guess it's not clear what I'm asking, so I suppose I should say... how do I do that? So we have DataContext.Customers (of type System.Data.Linq.Table) which wants to be replaced with a System.Collections.Generic.IEnumerable. I can't just assign the latter to the former because DataContext's properties are read only. But there must be a way. Edit: here's an image: Further edit: Yes, this image does not feature a collection of the type 'Customer' but rather 'Connection'. It doesn't matter though, they are both created from tables within the linked SQL database. So there is a dc.Connections, a dc.Customers, a dc.Media and so on. Thanks in advance.

• Wrong answer on c# application, finding the n prime of a list of prime numbers.

  - by user300484

  Hello, I am new to C# and I am practicing by trying to solve this easy C# problem. This application will receive an "n" number. After receiving this number, the program has to show the n prime of the list of primes. For example, if the user enters "3", the program is supposed to display "5", because 5 is the third prime starting at 2. I koow that something is wrong with my code but I dont know where is the problem and how I can fix it. Can you please tell me? Thank you :P using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Console.WriteLine("Determinar el n-esimo primo."); long n = Convert.ToInt64(Console.ReadLine()); // N lugar de primos long[] array = new long[n]; long c=0; while (c >= 2) { if(siprimo(c++) == true) for (long i = 0; i < n; i++) { array[i] = c; } } Console.WriteLine(array[n - 1]); Console.ReadLine(); } static private bool siprimo(long x) { bool sp = true; for (long k = 2; k <= x / 2; k++) if (x % k == 0) sp = false; return sp; } } }

• How to create an array of buttons in C++

  - by mangoman13

  Hi, I'm using C++ in VS2005 and have an 8x8 grid of buttons on a form. I want to have these buttons in an array, so when I click on any of them it will open the same event handler (I think that is what they are called), but I will know the index of which one was clicked on. I know how to do this in VB and C#, but I can't seem to figure it out with C++ Right now I have all my buttons labelled by their location, i.e. b00, b10, b21, etc. So I think what I am looking for is a way to do something like this: Button b[8][8]; //this causes me errors (error C2728: 'System::Windows::Forms::Button' : a native array cannot contain this managed type) and (error C2227: left of '->{ctor}' must point to class/struct/union/generic type) void Assignment(){ b[0][0] = b00; b[1][0] = b10; ... } and then in form1.h: private: System::Void b_Click(System::Object^ sender, System::EventArgs^ e) { //somehow read the coordinates into variables x and y //do something based on these values } Any help would be appreciated. Also let me know if I am going in the complete wrong direction with this. Thanks!

• extension methods with generics - when does caller need to include type parameters?

  - by Greg

  Hi, Is there a rule for knowing when one has to pass the generic type parameters in the client code when calling an extension method? So for example in the Program class why can I (a) not pass type parameters for top.AddNode(node), but where as later for the (b) top.AddRelationship line I have to pass them? class Program { static void Main(string[] args) { // Create Graph var top = new TopologyImp<string>(); // Add Node var node = new StringNode(); node.Name = "asdf"; var node2 = new StringNode(); node2.Name = "test child"; top.AddNode(node); top.AddNode(node2); top.AddRelationship<string, RelationshipsImp>(node,node2); // *** HERE *** } } public static class TopologyExtns { public static void AddNode<T>(this ITopology<T> topIf, INode<T> node) { topIf.Nodes.Add(node.Key, node); } public static INode<T> FindNode<T>(this ITopology<T> topIf, T searchKey) { return topIf.Nodes[searchKey]; } public static void AddRelationship<T,R>(this ITopology<T> topIf, INode<T> parentNode, INode<T> childNode) where R : IRelationship<T>, new() { var rel = new R(); rel.Child = childNode; rel.Parent = parentNode; } } public class TopologyImp<T> : ITopology<T> { public Dictionary<T, INode<T>> Nodes { get; set; } public TopologyImp() { Nodes = new Dictionary<T, INode<T>>(); } }

• My chance to shape our development process/policy

  - by Matt Luongo

  Hey guys, I'm sorry if this is a duplicate, but the question search terms are pretty generic. I work at a small(ish) development firm. I say small, but the company is actually a fair size; however, I'm only the second full-time developer, as most past work has been organized around contractors. I'm in a position to define internal project process and policy- obvious stuff like SCM and unit-testing. Methodology is outside the scope of the document I'm putting together, but I'd really like to push us in a leaner (and maybe even Agile?) direction. I feel like I have plenty of good practice recommendations, but not enough solid motivation to make my document the spirit guide I'd like it to be. I've separated the document into "principles" and "recommendations". Recommendations have been easy to come up with. Use SCM, strive for 1-step, regularly scheduled builds, unit test first, document as you go... Listing the principles that are supposed to be informing these recommendations, though, has been rough. I've come up with "tools work for us; we should never work for tools" and a hazy clause aimed at our QA (which has been overly manual) that I'd like to read "tedium is the root of all evil". I don't want to miss an opportunity with this document to give us a good in-house start and maybe even push us toward Agile. What principles am I missing?

• XSLT 1.0: restrict entries in a nodeset

  - by Mike

  Hi, Being relatively new to XSLT I have what I hope is a simple question. I have some flat XML files, which can be pretty big (eg. 7MB) that I need to make 'more hierarchical'. For example, the flat XML might look like this: <D0011> .... .... and it should end up looking like this: <D0011> .... .... I have a working XSLT for this, and it essentially gets a nodeset of all the b elements and then uses the 'following-sibling' axis to get a nodeset of the nodes following the current b node (ie. following-sibling::*[position() =$nodePos]). Then recursion is used to add the siblings into the result tree until another b element is found (I have parameterised it of course, to make it more generic). I also have a solution that just sends the position in the XML of the next b node and selects the nodes after that one after the other (using recursion) via a *[position() = $nodePos] selection. The problem is that the time to execute the transformation increases unacceptably with the size of the XML file. Looking into it with XML Spy it seems that it is the 'following-sibling' and 'position()=' that take the time in the two respective methods. What I really need is a way of restricting the number of nodes in the above selections, so fewer comparisons are performed: every time the position is tested, every node in the nodeset is tested to see if its position is the right one. Is there a way to do that ? Any other suggestions ? Thanks, Mike

• How to enumerate word document using office interop API?

  - by Shekhar

  Hello everyone, I want to traverse through all the elements of an word document one by one and according to type of element (header, sentence, table,image,textbox, shape, etc.) I want to process that element. I tried to search any enumerator or object which can represent elements of document in office interop API but failed to find any. API offers sentences, paragraphs, shapes collections but doesnt provide generic object which can point to next element. For example : <header of document> <plain text sentences> <table with many rows,columns> <text box> <image> <footer> (Please imagine it as a word document) So, now I want some enumerator which will first give me <header of document>, then on next iteration give me <plain text sentences>, then <table with many rows,columns> and so on. Does anyone knows how we can achieve this? Is it possible? I am using C#, visual studio 2005 and Word 2003. Thanks a lot

• Is this a hole in dynamic binding in C# 4?

  - by Galilyou

  I've seen a very interesting post on Fabio Maulo's blog. Here's the code and the bug if you don't want to jump to the url. I defined a new generic class like so: public class TableStorageInitializer<TTableEntity> where TTableEntity : class, new() { public void Initialize() { InitializeInstance(new TTableEntity()); } public void InitializeInstance(dynamic entity) { entity.PartitionKey = Guid.NewGuid().ToString(); entity.RowKey = Guid.NewGuid().ToString(); } } Note that InitializeInstance accepts one parameter, which is of type dynamic. Now to test this class, I defined another class that is nested inside my main Program class like so: class Program { static void Main(string[] args) { TableStorageInitializer<MyClass> x = new TableStorageInitializer<MyClass>(); x.Initialize(); } private class MyClass { public string PartitionKey { get; set; } public string RowKey { get; set; } public DateTime Timestamp { get; set; } } } Note: the inner class "MyClass" is declared private. Now if i run this code I get a "Microsoft.CSharp.RuntimeBinder.RuntimeBinderException" on the line "entity.PartitionKey = Guide.NewGuid().ToString()". The interesting part, though is that the message of the exception says "Object doesn't contain a definition for PartitionKey". Also note that if you changed the modifier of the nested class to public, the code will execute with no problems. So what do you guys think is really happening under the hood? Please refer to any documentation -of course if this is documented anywhere- that you may find?

• What to use for version control with Visual Studio 2008 for inhouse projects?

  - by Boog

  We want to put a number of our in-house projects under version control. Our projects are C# .NET applications and assemblies. We originally decided to go Microsoft all the way (as is the norm around here), and tried installing Visual Studio Team Foundation Server. To say the least, it was way more trouble of trying to get a successful install than it's worth, and I'm afraid we don't have a entire server to dedicate to TFS itself, as the installer seems to insist. We also considered a generic solution like Subversion or CVS, or possibly some kind of free online hosting that doesn't make our source publicly available under some license like Google Code appears to. Does anyone have any suggestions for us that would best fit our in-house MS environment? We'd also get some benefit out of some kind of project management tools if they were nicely integrated in to the solution, but this would only be a perk. I should also mention that we haven't entirely ruled out TFS, but it's looking like a pain, so anything you guys have to say for or against it would be helpful.

• OSMF seek with Amazon Cloudfront

  - by giorrrgio

  I've written a little OSMF player that streams via RTMP from Amazon Cloudfront. There's a known issue, the mp3 duration is not correctly readed from metadata and thus the seek function is not working. I know there's a workaround implying the use of getStreamLength function of NetConnection, which I successfully implemented in a previous non-OSMF player, but now I don't know how and when to call it, in terms of OSMF Events and Traits. This code is not working: protected function initApp():void { //the pointer to the media var resource:URLResource = new URLResource( STREAMING_PATH ); // Create a mediafactory instance mediaFactory = new DefaultMediaFactory(); //creates and sets the MediaElement (generic) with a resource and path element = mediaFactory.createMediaElement( resource ); var loadTrait:NetStreamLoadTrait = element.getTrait(MediaTraitType.LOAD) as NetStreamLoadTrait; loadTrait.addEventListener(LoaderEvent.LOAD_STATE_CHANGE, _onLoaded); player = new MediaPlayer( element ); //Marker 5: Add MediaPlayer listeners for media size and current time change player.addEventListener( DisplayObjectEvent.MEDIA_SIZE_CHANGE, _onSizeChange ); player.addEventListener( TimeEvent.CURRENT_TIME_CHANGE, _onProgress ); initControlBar(); } private function onGetStreamLength(result:Object):void { Alert.show("The stream length is " + result + " seconds"); duration = Number(result); } private function _onLoaded(e:LoaderEvent):void { if (e.newState == LoadState.READY) { var loadTrait:NetStreamLoadTrait = player.media.getTrait(MediaTraitType.LOAD) as NetStreamLoadTrait; if (loadTrait && loadTrait.netStream) { var responder:Responder = new Responder(onGetStreamLength); loadTrait.connection.call("getStreamLength", responder, STREAMING_PATH); } } }

• How do you deserialize a collection with child collections?

  - by Stuart Helwig

  I have a collection of custom entity objects one property of which is an ArrayList of byte arrays. The custom entity is serializable and the collection property is marked with the following attributes: [XmlArray("Images"), XmlArrayItem("Image",typeof(byte[]))] So I serialize a collection of these custom entities and pass them to a web service, as a string. The web service receives the string and byte array in tact, The following code then attempts to deserialize the collection - back into custom entities for processing... XmlSerializer ser = new XmlSerializer(typeof(List<myCustomEntity>)); StringReader reader = new StringReader(xmlStringPassedToWS); List<myCustomEntity> entities = (List<myCustomEntity>)ser.Deserialize(reader); foreach (myCustomEntity e in entities) { // ...do some stuff... foreach (myChildCollection c in entities.ChildCollection { // .. do some more stuff.... } } I've checked the XML resulting from the initial serialization and it does contain byte array - the child collection, as does the StringReader built above. After the deserialization process, the resulting collection of custom entites is fine, except that each object in the collection does not contain any items in its child collection. (i.e. it doesn't get to "...do some more stuff..." above. Can someone please explain what I am doing wrong? Is it possible to serialize ArrayLists within a generic collection of custom entities?

• Populate a tree from Hierarchical data using 1 LINQ statement

  - by Midhat

  Hi. I have set up this programming exercise. using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication2 { class DataObject { public int ID { get; set; } public int ParentID { get; set; } public string Data { get; set; } public DataObject(int id, int pid, string data) { this.ID = id; this.ParentID = pid; this.Data = data; } } class TreeNode { public DataObject Data {get;set;} public List<DataObject> Children { get; set; } } class Program { static void Main(string[] args) { List<DataObject> data = new List<DataObject>(); data.Add(new DataObject(1, 0, "Item 1")); data.Add(new DataObject(2, 0, "Item 2")); data.Add(new DataObject(21, 2, "Item 2.1")); data.Add(new DataObject(22, 2, "Item 2.2")); data.Add(new DataObject(221, 22, "Item 2.2.1")); data.Add(new DataObject(3, 0, "Item 3")); } } } The desired output is a List of 3 treenodes, having items 1, 2 and 3. Item 2 will have a list of 2 dataobjects as its children member and so on. I have been trying to populate this tree (or rather a forest) using just 1 SLOC using LINQ. A simple group by gives me the desired data but the challenge is to organize it in TreeNode objects. Can someone give a hint or an impossibility result for this?

• How to specify MQ channel table location for .net web application using web.config

  - by Matt

  I've been going around in circles for a while on this one now. I'm trying to connect to a distributed queue manager using a supplied channel table file. I can get this to work if I specify the environmental variable MQCHLLIB and MQCHLTAB on my server. However the IBM documentation states that the .net config file can override these variables. Here is what I have placed in my web.config file: ... <configSections> <section name="CHANNELS" type="System.Configuration.NameValueSectionHandler" /> </configSections> <CHANNELS> <add key="ChannelDefinitionDirectory" value="C:\temp"></add> <add key="ChannelDefinitionFile" value="DSM_MOM_TEST.tab"></add> </CHANNELS> ... And here is the code that is executing: Hashtable properties = new Hashtable(); //Add managed connection type to parameters. const String connectionType = MQC.TRANSPORT_MQSERIES_CLIENT; properties.Add(MQC.TRANSPORT_PROPERTY, connectionType); return new MQQueueManager(queueManagerName, properties); queueManagerName is set to the generic queue manager "*Q101T". However this isn't working and I get an error returned: 2058 MQRC_Q_MGR_NAME_ERROR I've been unable to find any more documentation on how to get this to work other than the environmental variables and the standard mqclient.ini should be overriden by the channels stanza in the web.config. Is there something that I've missed in the code? Any tips would be greatly appreciated.

• nServiceBus - Not all commands being received by handler

  - by SimonB

  In a test project based of the nServiceBus pub/sub sample, I've replace the bus.publish with bus.send in the server. The server sends 50 messages with a 1sec wait after each 5 (ie 10 burst of 5 messages). The client does not get all the messages. The soln has 3 projects - Server, Client, and common messages. The server and client are hosted via the nServiceBus generic host. Only a single bus is defined. Both client and server are configured to use StructureMap builder and BinarySerialisation. Server Endpoint: public class EndPointConfig : AsA_Publisher, IConfigureThisEndpoint, IWantCustomInitialization { public void Init() { NServiceBus.Configure.With() .StructureMapBuilder() .BinarySerializer(); } } Server Code : for (var nextId = 1; nextId <= 50; nextId++) { Console.WriteLine("Sending {0}", nextId); IDataMsg msg = new DataMsg { Id = nextId, Body = string.Format("Batch Msg #{0}", nextId) }; _bus.SendLocal(msg); Console.WriteLine(" ...sent {0}", nextId); if ((nextId % 5) == 0) Thread.Sleep(1000); } Client Endpoint: public class EndPointConfig : AsA_Client, IConfigureThisEndpoint, IWantCustomInitialization { public void Init() { NServiceBus.Configure.With() .StructureMapBuilder() .BinarySerializer(); } } Client Clode: public class DataMsgHandler : IMessageHandler<IDataMsg> { public void Handle(IDataMsg msg) { Console.WriteLine("DataMsgHandler.Handle({0}, {1}) - ({2})", msg.Id, msg.Body, Thread.CurrentThread.ManagedThreadId); } } Client and Server App.Config: <MsmqTransportConfig InputQueue="nsbt02a" ErrorQueue="error" NumberOfWorkerThreads="1" MaxRetries="5" /> <UnicastBusConfig DistributorControlAddress="" DistributorDataAddress=""> <MessageEndpointMappings> <add Messages="Test02.Messages" Endpoint="nsbt02a" /> </MessageEndpointMappings> </UnicastBusConfig> All run via VisualStudio 2008.

• Adding class constraints to typeclass instance

  I'm trying to implement the Cantor Pairing Function, as an instance of a generic Pair typeclass, as so: module Pair (Pair, CantorPair) where -- Pair interface class Pair p where pi :: a -> a -> p a k :: p a -> a l :: p a -> a -- Wrapper for typing newtype CantorPair a = P { unP :: a } -- Assume two functions with signatures: cantorPair :: Integral a => a -> a -> CantorPair a cantorUnpair :: Integral a => CantorPair a -> (a, a) -- I need to somehow add an Integral a constraint to this instance, -- but I can't work out how to do it. instance Pair CantorPair where pi = cantorPair k = fst . cantorUnpair l = snd . cantorUnpair How can I add the appropriate Integral constraint to the instance? I have a vague feeling I might need to modify the Pair interface itself, but not sure how to go about this.

• A "smart" (forgiving) date parser?

  - by jdmuys

  I have to migrate a very large dataset from one system to another. One of the "source" column contains a date but is really a string with no constraint, while the destination system mandates a date in the format yyyy-mm-dd. Many, but not all, of the source dates are formatted as yyyymmdd. So to coerce them to the expected format, I do (in Perl): return "$1-$2-$3" if ($val =~ /(\d{4})[-\/]*(\d{2})[-\/]*(\d{2})/); The problem arises when the source dates moves away from the "generic" yyyymmdd. The goal is to salvage as many dates as possible, before giving up. Example source strings include: 21/3/1998, March 2004, 2001, 3/4/97 I can try to match as many of the examples I can find with a succession of regular expressions such as the one above. But is there something smarter to do? Am I not reinventing the wheel? Is there a library somewhere doing something similar? I couldn't find anything relevant googling "forgiving date parser". (any language is OK).

• Alternatives to static methods on interfaces for enforcing consistency

  - by jayshao

  In Java, I'd like to be able to define marker interfaces, that forced implementations to provide static methods. For example, for simple text-serialization/deserialization I'd like to be able to define an interface that looked something like this: public interface TextTransformable<T>{ public static T fromText(String text); public String toText(); Since interfaces in Java can't contain static methods though (as noted in a number of other posts/threads: here, here, and here this code doesn't work. What I'm looking for however is some reasonable paradigm to express the same intent, namely symmetric methods, one of which is static, and enforced by the compiler. Right now the best we can come up with is some kind of static factory object or generic factory, neither of which is really satisfactory. Note: in our case our primary use-case is we have many, many "value-object" types - enums, or other objects that have a limited number of values, typically carry no state beyond their value, and which we parse/de-parse thousands of time a second, so actually do care about reusing instances (like Float, Integer, etc.) and its impact on memory consumption/g.c. Any thoughts?

• opening a new page and passing a parameter to it with Javascript

  - by recipriversexclusion

  I have a JS function that processes XML I GET from a server to dynamically create a table as below // Generate table of services by parsing the returned XML service list. function convertServiceXmlDataToTable(xml) { var tbodyElem = document.getElementById("myTbody"); var trElem, tdElem; var j = 0; $(xml).find("Service").each(function() { trElem = tbodyElem.insertRow(tbodyElem.rows.length); trElem.className = "tr" + (j % 2); // first column -> service ID var serviceID = $(this).attr("service__id"); tdElem = trElem.insertCell(trElem.cells.length); tdElem.className = "col0"; tdElem.innerHTML = serviceID; // second column -> service name tdElem = trElem.insertCell(trElem.cells.length); tdElem.className = "col1"; tdElem.innerHTML = "<a href=javascript:showServiceInfo(" + serviceID + ")>" + $(this).find("name").text() + "</a>"; j++; }); // each service } where showServiceInfo retrieves more detailed information about each service from the server based on the serviceID and displays it in the same page as the services table. So far so good. But, it turns out that I have to display the detailed service information in another page rather than the same page as the table. I have creates a generic service_info.html with an empty layout template, but I don't understand how to pass serviceID to this new page so that it gets customized with the detailed service info. How can I do this? Or, is there a better way to handle these situations? Thanks!

• Utility of List<T>.Sort() versus List<T>.OrderBy() for a member of a custom container class

  - by ccomet

  I've found myself running back through some old 3.5 framework legacy code, and found some points where there are a whole bunch of lists and dictionaries that must be updated in a synchronized fashion. I've determined that I can make this process infinitely easier to both utilize and understand by converging these into custom container classes of new custom classes. There are some points, however, where I came to concerns with organizing the contents of these new container classes by a specific inner property. For example, sorting by the ID number property of one class. As the container classes are primarily based around a generic List object, my first instinct was to write the inner classes with IComparable, and write the CompareTo method that compares the properties. This way, I can just call items.Sort() when I want to invoke the sorting. However, I've been thinking instead about using items = items.OrderBy(Func) instead. This way it is more flexible if I need to sort by any other property. Readability is better as well, since the property used for sorting will be listed in-line with the sort call rather than having to look up the IComparable code. The overall implementation feels cleaner as a result. I don't care for premature or micro optimization, but I like consistency. I find it best to stick with one kind of implementation for as many cases as it is appropriate, and use different implementations where it is necessary. Is it worth it to convert my code to use the LINQ OrderBy instead of using List.Sort? Is it a better practice to stick with the IComparable implementation for these custom containers? Are there any significant mechanical advantages offered by either path that I should be weighing the decision on? Or is their end-functionality equivalent to the point that it just becomes coder's preference?

• Silverlight: How can I built an overview display block for any XAML?

  - by Ryan Bates

  Hi all, I am trying to create a generic "overview" control for any XAML. A good example of the desired effect would be on Google Maps or Bing maps: The main map zooms into some content, while a small "overview" block is docked to one of the map corners, showing the user where he/she is zoomed into. My content is all placed inside a <Canvas>, which can then be scaled and zoomed with transforms. While the user does this kind of navigation, I would like to give them a visual indication of where they are in the larger context of the content. I have tried to take a 'screenshot' of the XAML before the user starts navigating, i.e. create a WriteableBitmap wbImageData = new WriteableBitmap(TheCanvas, null); and then displaying it in an Image. Based on the user's scrolling and zooming activity, a Rectangle displays which part of the content is currently visible in the display area. This works OK-ish (still clunky), but the image has to be redone everytime the content changes. Is there a simple way to create this kind of preview, or does anyone know of a component that does it? Thanks!

• Sharepoint user details not visible to other users

  - by richardoz

  I am managing a SharePoint site that uses Form Based Authentication. We have several generic lists, document libraries and active task lists that users can create update and delete. Users can use the people pickers to select/search for everyone. But the users cannot see other users names, email addresses etc. in display lists or the people pickers. If I log in as the site collection administrator, I can see everyones details. So I know the data is available. Updated details on this problem (non-administrators) SharePoint users cannot see other users information. Example: User A assigns a task to user B. User A creates a new task and uses the people picker to find user B. User B is only visible by the login name “bname” and any information about user B is not visible or searchable within the people picker. Once user B is assigned the task, user A no longer sees the name in the task list – even though user A created it. No modified by, created by, assigned to or owner field data is visible to non-administrator users. Facts: Extranet site is configured to use Forms Based Authentication. Intranet uses windows based authentication Users of both the intranet and extranet have the same problem All databases are local The site uses SSRS integration SharePoint WSS on Windows 2003 Std -- After activating the verbose logging it looks like SharePoint is definately asking SQL server for only the user info for the currently logged in user: SELECT TOP 6 /lots-of-columns/ FROM UserData INNER MERGE JOIN Docs AS t1 ON ( 1 = 1 AND UserData.[tp_RowOrdinal] = 0 AND t1.SiteId = UserData.tp_SiteId AND t1.SiteId = @L2 AND t1.DirName = UserData.tp_DirName AND t1.LeafName = UserData.tp_LeafName AND t1.Level = UserData.tp_Level AND t1.IsCurrentVersion = 1 AND (1 = 1) ) LEFT OUTER JOIN AllUserData AS t2 ON ( UserData.[tp_Author]=t2.[tp_ID] AND UserData.[tp_RowOrdinal] = 0 AND t2.[tp_RowOrdinal] = 0 AND ( (t2.tp_IsCurrent = 1) ) AND t2.[tp_CalculatedVersion] = 0 AND t2.[tp_DeleteTransactionId] = 0x AND t2.tp_ListId = @L3 AND UserData.tp_ListId = @L4 AND t2.[tp_Author]=162 /* this is the currently logged in user */ ) WHERE (UserData.tp_IsCurrent = 1) AND UserData.tp_SiteId=@L2 AND (UserData.tp_DirName=@DN) AND UserData.tp_RowOrdinal=0 AND ( ( (UserData.[datetime1] IS NULL ) OR (UserData.[datetime1] = @L5DTP) ) AND t1.SiteId=@L2 AND (t1.DirName=@DN) ) ORDER BY UserData.[tp_Modified] Desc, UserData.[tp_ID] Asc Again, any ideas would be appreciated.
