Gotcha: use parentheses around ternary op conditional expressions
25 Αυγούστου 18 03:42 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Just came across the following case in C# that puzzled me momentarily, especially since the strings involved were long enough and the expression was broken on multiple lines: bool flag = true; string test1 = flag? "xa" : "xb"; string test2 = "x" + (flag? "a" : "b"); string test3 = "x" + flag? "a" […]

Suggestion: on Duck Typing and C#/.NET
16 Νοεμβρίου 15 03:32 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

My comment at: http://visualstudio.uservoice.com/forums/121579-visual-studio-2015/suggestions/4272089-support-implicit-interfaces-for-code-reuse It would be nice indeed if one could define at the client object’s side a static interface that is a subset of the methods of a server (or serving if you prefer) object (it is only the view of the server that the client has gained knowledge of) that has been […]

Suggestion: Add support for constants in C# (and VB.net etc.) interfaces
16 Νοεμβρίου 15 12:52 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

It is rather unfortunate that C# doesn’t support constants in interfaces, whereas Java does. If IL (intermediate language) that C# usually compiles to (when not using AOT that is like in .NET Native or Xamarin iOS) doesn’t support this, then the compiler could create a special sealed class to carry the constants. Then, wherever they’re […]

Suggestion: Define once and reuse result type of method inside its body
10 Νοεμβρίου 15 11:58 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

It would be nice if one could rewrite this C# snippet: public SortedDictionary<string, UObject> GetObjects() {   SortedDictionary<string, UObject> result = new SortedDictionary<string, UObject>();   using (ReadTransaction xact = namingSchema.ReadTransaction())     foreach (ObjectName.RowType row in ObjectName.object_name_(xact))       result.Add(row.name_, row.object_);   return result; }   in a more concise form like:   public T GetObjects() where T=SortedDictionary<string, UObject> {   T result […]

Suggestion: Allow new in C# without giving Type
23 Αυγούστου 15 01:12 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

This is a suggestion I’ve just sent in via Visual Studio’s “Send a frown” feature: Instead of writing statements like:   List<CultureInfo> result = new List<CultureInfo>(); in C# I’d prefer to be able to write   List<CultureInfo> result = new (); inside the () one would be able to pass contructor parameters and also they […]

Suggestion: Case adaptive text replacement in Visual Studio editor
16 Μαρτίου 15 05:28 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Have again suggested this long before to Visual Studio team, but since Visual Studio 2013 has a “Send a Frown” feature, I’ve sent it again with some suggestions on how it could be implemented. I need some clever replace in cases like that one shown in the screenshot below, where I have the implementation of […]

HowTo: Call C# method from class that has same name as namespace
06 Ιουλίου 14 03:25 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

In the C# compiler error case shown above, CaptionsGrid class exists in namespace ClipFlair.CaptionsGrid so in the code we have “using ClipFlair.CaptionsGrid;” at the top of the file where we want to call the “SaveAudio” static method of CaptionsGrid class. But then we get the error “The type or namespace name ‘…’ does not exist […]

Fix: Visual Studio opens class diagram in XML editor with double click
10 Φεβρουαρίου 13 12:00 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Recently, to save myself sometime after having renamed some interfaces/classes in the ClipFlair project sourcecode, I right-clicked one of the class diagrams (.cd files) in it at Visual Studio’s “Solution Navigator” (this is an enhanced Solution Explorer addon) and using “Open With…” I opened up the diagrams with the XML editor to do a rename-all [...]

HowTo: Make Project Linker extension’s VSIX install at Visual Studio 2012
27 Νοεμβρίου 12 10:24 πμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Project Linker is a Visual Studio Extension that “helps to automatically create and maintain links from a source project to a target project to share code that is common to Silverlight and WPF”. In ClipFlair, where I have shared code between a Silverlight and a WPF project (I guess same would be for XNA projects [...]

HowTo: Type in double-quote in Windows Live Writer
14 Αυγούστου 12 10:08 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

A big nuissance in Windows Live Writer is that when you try to type in a double-quote character you get some special Unicode character (“ or ”, at the start and end of a string respectively), other than the classic ASCII character used in programming. That way people copy-pasting snippets from your blog can get [...]

Collection of useful links for .NET, Silverlight, WPF etc. development
05 Ιουλίου 12 12:22 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

During the development of ClipFlair (currently at Alpha1-internal version), I’ve been doing lots of research, hunting for information (documentation, related discussion threads, useful download links) needed when writing and refactoring source code etc. I have tried to organize these links as (Windows) Internet shortcut files into folders. They do need some further restructuring, but they [...]

VB gotcha: when If function isn’t equivalent to an If-Then-Else block
25 Νοεμβρίου 11 01:07 μμ | Μπιρμπίλης Γεώργιος | 0 σχόλια   

Just got bitten by the following: Dim takeN As Integer = If(Integer.TryParse(EdTake.Text, takeN), takeN, itemsCount) I had used that instead of writing in 2 lines: Dim takeN As Integer If not Integer.TryParse(EdTake.Text, takeN) then takeN = itemsCount However, there’s an important difference: “If” is a function, so its arguments are evaluated at call-time. The “If” [...]
