• C# Proposal: Compile Time Static Checking Of Dynamic Objects

  - by Paulo Morgado

  C# 4.0 introduces a new type: dynamic. dynamic is a static type that bypasses static type checking. This new type comes in very handy to work with: The new languages from the dynamic language runtime. HTML Document Object Model (DOM). COM objects. Duck typing … Because static type checking is bypassed, this: dynamic dynamicValue = GetValue(); dynamicValue.Method(); is equivalent to this: object objectValue = GetValue(); objectValue .GetType() .InvokeMember( "Method", BindingFlags.InvokeMethod, null, objectValue, null); Apart from caching the call site behind the scenes and some dynamic resolution, dynamic only looks better. Any typing error will only be caught at run time. In fact, if I’m writing the code, I know the contract of what I’m calling. Wouldn’t it be nice to have the compiler do some static type checking on the interactions with these dynamic objects? Imagine that the dynamic object that I’m retrieving from the GetValue method, besides the parameterless method Method also has a string read-only Property property. This means that, from the point of view of the code I’m writing, the contract that the dynamic object returned by GetValue implements is: string Property { get; } void Method(); Since it’s a well defined contract, I could write an interface to represent it: interface IValue { string Property { get; } void Method(); } If dynamic allowed to specify the contract in the form of dynamic(contract), I could write this: dynamic(IValue) dynamicValue = GetValue(); dynamicValue.Method(); This doesn’t mean that the value returned by GetValue has to implement the IValue interface. It just enables the compiler to verify that dynamicValue.Method() is a valid use of dynamicValue and dynamicValue.OtherMethod() isn’t. If the IValue interface already existed for any other reason, this would be fine. But having a type added to an assembly just for compile time usage doesn’t seem right. So, dynamic could be another type construct. Something like this: dynamic DValue { string Property { get; } void Method(); } The code could now be written like this; DValue dynamicValue = GetValue(); dynamicValue.Method(); The compiler would never generate any IL or metadata for this new type construct. It would only thee used for compile type static checking of dynamic objects. As a consequence, it makes no sense to have public accessibility, so it would not be allowed. Once again, if the IValue interface (or any other type definition) already exists, it can be used in the dynamic type definition: dynamic DValue : IValue, IEnumerable, SomeClass { string Property { get; } void Method(); } Another added benefit would be IntelliSense. I’ve been getting mixed reactions to this proposal. What do you think? Would this be useful?

• Convert a Row to a Column in Excel the Easy Way

  - by Matthew Guay

  Sometimes we’ve entered data in a column in Excel, only to realize later that it would be better to have this data in a row, or vise-versa.  Here’s a simple trick to convert any row or set of rows into a column, or vise-versa, in Excel. Please Note: This is tested in Excel 2003, 2007, and 2010.  Here we took screenshots from Excel 2010 x64, but it works the same on the other versions. Convert a Row to a Column Here’s our data in Excel: We want to change these two columns into rows.  Select all the cells you wish to convert, right-click, and select copy (or simply press Ctrl+C): Now, right-click in the cell where you want to put the data in rows, and select “Paste Special…”   Check the box at the bottom that says “Transpose”, and then click OK. Now your data that was in columns is in rows! This works the exact same for converting rows into columns.  Here’s some data in rows:   After copying and pasting special with Transpose selected, here’s the data in columns! This is a great way to get your data organized just like you want in Excel.

• TFS Build Server not finding 'Microsoft.Expression.Interactions&rsquo;

  - by Chris Skardon

  We’ve been trying to get the build server to pick up the Microsoft.Expression.Interactions.dll needed so we can use things like the ExtendedVisualStateManager and the DataStateBehavior. Adding the DataStateBehavior in Blend adds the reference to the project, so it all compiles fine on the local machine. Checking in the code into a CI server throws up some ugliness: d:\Builds\6\Source\MyFile.xaml (290): The tag 'DataStateBehavior' does not exist in XML namespace 'http://schemas.microsoft.com/expression/2010/interactions'. Errr, it should do…?? The reference is there, so… ahhhhh! A quick check of the properties and we’re using the dll from the c:\program files (x86)\ location, no wonder the build server can’t find it – let’s add the dll into our (ever expanding) ‘lib’ folder, reference that version, and check that bad boy in… No. Still No. Still get the same error. What the??? The reference is still pointing to the program files location?? Ok, so let’s modify the csproj file using the wonderful notepad, changing the reference from <Reference Include="Microsoft.Expression.Interactions, /* loadsa shizzle here */ /> to <Reference Include="Microsoft.Expression.Interactions">     <HintPath>..\Lib\Microsoft.Expression.Interactions.dll</HintPath> </Reference> Check that in, aaaand… Success!!! The reason for this (from what I can gather from here) is that we’re using the Productivity Power Tools, and they try to be clever about referencing dlls, and changed what we’d asked (i.e. for the local version) to use the original program files location.. Editing the file in notepad (sweet sweet notepad) gets around this issue… Irritating, took a while to figure this out… Meh :)

• C# 4.0: Alternative To Optional Arguments

  - by Paulo Morgado

  Like I mentioned in my last post, exposing publicly methods with optional arguments is a bad practice (that’s why C# has resisted to having it, until now). You might argument that your method or constructor has to many variants and having ten or more overloads is a maintenance nightmare, and you’re right. But the solution has been there for ages: have an arguments class. The arguments class pattern is used in the .NET Framework is used by several classes, like XmlReader and XmlWriter that use such pattern in their Create methods, since version 2.0: XmlReaderSettings settings = new XmlReaderSettings(); settings.ValidationType = ValidationType.Auto; XmlReader.Create("file.xml", settings); With this pattern, you don’t have to maintain a long list of overloads and any default values for properties of XmlReaderSettings (or XmlWriterSettings for XmlWriter.Create) can be changed or new properties added in future implementations that won’t break existing compiled code. You might now argue that it’s too much code to write, but, with object initializers added in C# 3.0, the same code can be written like this: XmlReader.Create("file.xml", new XmlReaderSettings { ValidationType = ValidationType.Auto }); Looks almost like named and optional arguments, doesn’t it? And, who knows, in a future version of C#, it might even look like this: XmlReader.Create("file.xml", new { ValidationType = ValidationType.Auto });

• C# 4.0: COM Interop Improvements

  - by Paulo Morgado

  Dynamic resolution as well as named and optional arguments greatly improve the experience of interoperating with COM APIs such as Office Automation Primary Interop Assemblies (PIAs). But, in order to alleviate even more COM Interop development, a few COM-specific features were also added to C# 4.0. Ommiting ref Because of a different programming model, many COM APIs contain a lot of reference parameters. These parameters are typically not meant to mutate a passed-in argument, but are simply another way of passing value parameters. Specifically for COM methods, the compiler allows to declare the method call passing the arguments by value and will automatically generate the necessary temporary variables to hold the values in order to pass them by reference and will discard their values after the call returns. From the point of view of the programmer, the arguments are being passed by value. This method call: object fileName = "Test.docx"; object missing = Missing.Value; document.SaveAs(ref fileName, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); can now be written like this: document.SaveAs("Test.docx", Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value); And because all parameters that are receiving the Missing.Value value have that value as its default value, the declaration of the method call can even be reduced to this: document.SaveAs("Test.docx"); Dynamic Import Many COM methods accept and return variant types, which are represented in the PIAs as object. In the vast majority of cases, a programmer calling these methods already knows the static type of a returned object form the context of the call, but has to explicitly perform a cast on the returned values to make use of that knowledge. These casts are so common that they constitute a major nuisance. To make the developer’s life easier, it is now possible to import the COM APIs in such a way that variants are instead represented using the type dynamic which means that COM signatures have now occurrences of dynamic instead of object. This means that members of a returned object can now be easily accessed or assigned into a strongly typed variable without having to cast. Instead of this code: ((Excel.Range)(excel.Cells[1, 1])).Value2 = "Hello World!"; this code can now be used: excel.Cells[1, 1] = "Hello World!"; And instead of this: Excel.Range range = (Excel.Range)(excel.Cells[1, 1]); this can be used: Excel.Range range = excel.Cells[1, 1]; Indexed And Default Properties A few COM interface features are still not available in C#. On the top of the list are indexed properties and default properties. As mentioned above, these will be possible if the COM interface is accessed dynamically, but will not be recognized by statically typed C# code. No PIAs – Type Equivalence And Type Embedding For assemblies indentified with PrimaryInteropAssemblyAttribute, the compiler will create equivalent types (interfaces, structs, enumerations and delegates) and embed them in the generated assembly. To reduce the final size of the generated assembly, only the used types and their used members will be generated and embedded. Although this makes development and deployment of applications using the COM components easier because there’s no need to deploy the PIAs, COM component developers are still required to build the PIAs.

• The Evolution Of C#

  - by Paulo Morgado

  The first release of C# (C# 1.0) was all about building a new language for managed code that appealed, mostly, to C++ and Java programmers. The second release (C# 2.0) was mostly about adding what wasn’t time to built into the 1.0 release. The main feature for this release was Generics. The third release (C# 3.0) was all about reducing the impedance mismatch between general purpose programming languages and databases. To achieve this goal, several functional programming features were added to the language and LINQ was born. Going forward, new trends are showing up in the industry and modern programming languages need to be more: Declarative With imperative languages, although having the eye on the what, programs need to focus on the how. This leads to over specification of the solution to the problem in hand, making next to impossible to the execution engine to be smart about the execution of the program and optimize it to run it more efficiently (given the hardware available, for example). Declarative languages, on the other hand, focus only on the what and leave the how to the execution engine. LINQ made C# more declarative by using higher level constructs like orderby and group by that give the execution engine a much better chance of optimizing the execution (by parallelizing it, for example). Concurrent Concurrency is hard and needs to be thought about and it’s very hard to shoehorn it into a programming language. Parallel.For (from the parallel extensions) looks like a parallel for because enough expressiveness has been built into C# 3.0 to allow this without having to commit to specific language syntax. Dynamic There was been lots of debate on which ones are the better programming languages: static or dynamic. The fact is that both have good qualities and users of both types of languages want to have it all. All these trends require a paradigm switch. C# is, in many ways, already a multi-paradigm language. It’s still very object oriented (class oriented as some might say) but it can be argued that C# 3.0 has become a functional programming language because it has all the cornerstones of what a functional programming language needs. Moving forward, will have even more. Besides the influence of these trends, there was a decision of co-evolution of the C# and Visual Basic programming languages. Since its inception, there was been some effort to position C# and Visual Basic against each other and to try to explain what should be done with each language or what kind of programmers use one or the other. Each language should be chosen based on the past experience and familiarity of the developer/team/project/company and not by particular features. In the past, every time a feature was added to one language, the users of the other wanted that feature too. Going forward, when a feature is added to one language, the other will work hard to add the same feature. This doesn’t mean that XML literals will be added to C# (because almost the same can be achieved with LINQ To XML), but Visual Basic will have auto-implemented properties. Most of these features require or are built on top of features of the .NET Framework and, the focus for C# 4.0 was on dynamic programming. Not just dynamic types but being able to talk with anything that isn’t a .NET class. Also introduced in C# 4.0 is co-variance and contra-variance for generic interfaces and delegates. Stay tuned for more on the new C# 4.0 features.

• Microsoft Remote Desktop Services - Android

  - by Matt Rogers

  We have recently started testing Remote Desktop Services. We have deployed the environment using the latest server, Windows Server 2012 R2. We have deployed the Web Access Roles, RD Gateway, Connection Broker Virtualization Host and Session Host. We are running both, Virtual machine-based and Session-based deployments. All of these are working as expected internally and externally when using a Windows workstation as the RDS client, however, the Android client is unable to launch applications. Once you install the app from Google Play you are given a screen to add Remote Resources. After entering the appropriate URL, username and password we see the applications that have been published. Unfortunately, when we attempt to launch an app we get the following error: Connection Error Host not found. Please provide the fully-qualified name or the IP address of the host. We have already entered this information otherwise I don't believe we would be able to see the published applications. I think the error is related to the certificate and how it is being used to connect to the applications. Since this is in our lab environment we have not configured a valid external certificate on the servers and the trusted certificate that is installed on the android tablet points to our internal server / domain name. What I would like to know: Has anyone configured RDS Web Access on Server 2012 R2 and attempted to externally connect an Android or iOS device using the Microsoft supported Remote Desktop client. Are others experiencing the same problem we are? Were you able to resolve the issue? Was it related to the external cert / host name?

• C# 4.0: Covariance And Contravariance In Generics Made Easy

  - by Paulo Morgado

  In my last post, I went through what is variance in .NET 4.0 and C# 4.0 in a rather theoretical way. Now, I’m going to try to make it a bit more down to earth. Given: class Base { } class Derived : Base { } Such that: Trace.Assert(typeof(Base).IsClass && typeof(Derived).IsClass && typeof(Base).IsGreaterOrEqualTo(typeof(Derived))); Covariance interface ICovariantIn<out T> { } Trace.Assert(typeof(ICovariantIn<Base>).IsGreaterOrEqualTo(typeof(ICovariantIn<Derived>))); Contravariance interface ICovariantIn<out T> { } Trace.Assert(typeof(IContravariantIn<Derived>).IsGreaterOrEqualTo(typeof(IContravariantIn<Base>))); Invariance interface IInvariantIn<T> { } Trace.Assert(!typeof(IInvariantIn<Base>).IsGreaterOrEqualTo(typeof(IInvariantIn<Derived>)) && !typeof(IInvariantIn<Derived>).IsGreaterOrEqualTo(typeof(IInvariantIn<Base>))); Where: public static class TypeExtensions { public static bool IsGreaterOrEqualTo(this Type self, Type other) { return self.IsAssignableFrom(other); } }

• [Windows 8] Application bar buttons symbols

  - by Benjamin Roux

  During the development of my current Windows 8 application, I wanted to add custom application bar buttons with symbols that were not available in the StandardStyle.xaml file created with the template project. First I tried to Bing some new symbols and I found this blog post by Tim Heuer with the list of all symbols available (supposedly) but the one I wanted was not there (a heart). In this blog post I’m going the show you how to retrieve all the symbols available without creating a custom path. First you have to start the “Character map” tool and select “Segoe UI Symbol” then go at the end of the grid to see all the symbols available. When you want one just select it and copy it’s code inside the content of your Button. In my case I wanted a heart and its code is “E0A5”, so my button (or style in this case) became <Style x:Key="LoveAppBarButtonStyle" TargetType="Button" BasedOn="{StaticResource AppBarButtonStyle}"> <Setter Property="AutomationProperties.AutomationId" Value="LoveAppBarButtonStyle"/> <Setter Property="AutomationProperties.Name" Value="Love"/> <Setter Property="Content" Value="&#xE0A5;"/> </Style> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Et voila. Hope this will help you (there is A LOT of symbols")!

• Access .accdb format’s

  - by wisecarver

  Were you aware there are two versions of the Access .accdb file format? The 2007 “ACE” version and the 2010 “ACE” version both use different drivers. If you’ve tried to use the Access Database .accdb format on DiscountASP.NET servers and it failed you must have been using a Data file created with the 2010 version of Access. OK, you’re shouting at me right now for even suggesting Access Databases for Shared hosting, right? I agree, SQL Server is the way to go and I personally help a lot of developers...(read more)

• C# 4.0: Covariance And Contravariance In Generics

  - by Paulo Morgado

  C# 4.0 (and .NET 4.0) introduced covariance and contravariance to generic interfaces and delegates. But what is this variance thing? According to Wikipedia, in multilinear algebra and tensor analysis, covariance and contravariance describe how the quantitative description of certain geometrical or physical entities changes when passing from one coordinate system to another.(*) But what does this have to do with C# or .NET? In type theory, a the type T is greater (>) than type S if S is a subtype (derives from) T, which means that there is a quantitative description for types in a type hierarchy. So, how does covariance and contravariance apply to C# (and .NET) generic types? In C# (and .NET), variance applies to generic type parameters and not to the resulting generic type. A generic type parameter is: covariant if the ordering of the generic types follows the ordering of the generic type parameters: Generic<T> = Generic<S> for T = S. contravariant if the ordering of the generic types is reversed from the ordering of the generic type parameters: Generic<T> = Generic<S> for T = S. invariant if neither of the above apply. If this definition is applied to arrays, we can see that arrays have always been covariant because this is valid code: object[] objectArray = new string[] { "string 1", "string 2" }; objectArray[0] = "string 3"; objectArray[1] = new object(); However, when we try to run this code, the second assignment will throw an ArrayTypeMismatchException. Although the compiler was fooled into thinking this was valid code because an object is being assigned to an element of an array of object, at run time, there is always a type check to guarantee that the runtime type of the definition of the elements of the array is greater or equal to the instance being assigned to the element. In the above example, because the runtime type of the array is array of string, the first assignment of array elements is valid because string = string and the second is invalid because string = object. This leads to the conclusion that, although arrays have always been covariant, they are not safely covariant – code that compiles is not guaranteed to run without errors. In C#, the way to define that a generic type parameter as covariant is using the out generic modifier: public interface IEnumerable<out T> { IEnumerator<T> GetEnumerator(); } public interface IEnumerator<out T> { T Current { get; } bool MoveNext(); } Notice the convenient use the pre-existing out keyword. Besides the benefit of not having to remember a new hypothetic covariant keyword, out is easier to remember because it defines that the generic type parameter can only appear in output positions — read-only properties and method return values. In a similar way, the way to define a type parameter as contravariant is using the in generic modifier: public interface IComparer<in T> { int Compare(T x, T y); } Once again, the use of the pre-existing in keyword makes it easier to remember that the generic type parameter can only be used in input positions — write-only properties and method non ref and non out parameters. Because covariance and contravariance apply only to the generic type parameters, a generic type definition can have both covariant and contravariant generic type parameters in its definition: public delegate TResult Func<in T, out TResult>(T arg); A generic type parameter that is not marked covariant (out) or contravariant (in) is invariant. All the types in the .NET Framework where variance could be applied to its generic type parameters have been modified to take advantage of this new feature. In summary, the rules for variance in C# (and .NET) are: Variance in type parameters are restricted to generic interface and generic delegate types. A generic interface or generic delegate type can have both covariant and contravariant type parameters. Variance applies only to reference types; if you specify a value type for a variant type parameter, that type parameter is invariant for the resulting constructed type. Variance does not apply to delegate combination. That is, given two delegates of types Action<Derived> and Action<Base>, you cannot combine the second delegate with the first although the result would be type safe. Variance allows the second delegate to be assigned to a variable of type Action<Derived>, but delegates can combine only if their types match exactly. If you want to learn more about variance in C# (and .NET), you can always read: Covariance and Contravariance in Generics — MSDN Library Exact rules for variance validity — Eric Lippert Events get a little overhaul in C# 4, Afterward: Effective Events — Chris Burrows Note: Because variance is a feature of .NET 4.0 and not only of C# 4.0, all this also applies to Visual Basic 10.

• How to Add a Note to an Email Message in Outlook 2013

  - by Lori Kaufman

  There may be times when you want to add a note to an email message you received. Maybe you need to remember something about the sender or the contents of the email. There are several ways to add a note to an email message. NOTE: You can also create a new task containing an email message you received. This is useful if you need to do something related to the email. The new task will contain all the contents (except attachments) from the email. One method of adding a note to an email message is to flag the message. To do this, right-click on the flag icon in the flag column for the message to which you want to add a note. Select Custom from the popup menu. On the Custom dialog box, you can select a ready-made note from the Flag to drop-down list. You can also type a custom note in the Flag to edit box. Select a Start date and a Due date and setup a reminder, if desired. Click OK. The flag displays above the body of the email message when you double-click on the message to open it in the Message window. You can also put the cursor in the subject line of the message and add text to it, as shown below. When you close the message window, a confirmation dialog box displays asking if you want to save your changes. To save the note you added to the subject line, click Yes. Your note displays as part of the subject line on the message in your list of email messages. You can also add a note to the body of an email message. To do this, you must enable editing of the message. Double-click the message to open the Message window. Click Actions in the Move section of the Message tab and select Edit Message from the drop-down menu. Click in the body of the message and type your note. When you close the Message window, a confirmation dialog box displays asking if you want to save your changes. Click Yes to save you note in the body of the email. You can see the note you added if it is visible as part of the first line of the body displayed in the list of email messages. Use the Notes section of Outlook to create a separate note you can attach to an email message. To do this, click the … button on the Navigation Bar and select Notes from the popup menu. Click New Note on the Home tab of the Notes window (or press Ctrl + N) to create a note. Enter the text for your note in the small note window that displays and click the X button to close the note, saving it. To attach the note to the email message, make sure the Mail section of Outlook is active. Double-click on the message onto which you want to attach the note. Leaving the Message window open, go back to the main Outlook window and select Notes from the Navigation Bar, as mentioned above. Drag the note you created to the message window. The note is added to the message as an attachment. When you close the Message window, a confirmation dialog box displays asking if you want to save your changes. To save the message with your note added as an attachment, click Yes. A paperclip icon is added to the message in the list of email messages, indicating there is an attachment in the message. When you add a note to an email message as an attachment using the Notes section of Outlook, you don’t have to keep the original note. The note is now saved with the message, and can be deleted from the Notes section.

• HTG Explains: What’s the Difference Between CC and BCC When Sending an Email?

  - by Chris Hoffman

  The CC and BCC fields when sending email work similarly. CC stands for “carbon copy,” while BCC stands for “blind carbon copy.” While these terms may have been immediately obvious when email was invented, they’re antiquated today. CC and BCC are both ways of sending copies of an email to additional people. However, you can also send copies of an email to additional people by specifying multiple addresses in the To field.
