Hi, Is there a standard (framework) mapping between CLR types and xsd type codes. I need to convert a string, int, decimal etc to the equivalent XmlSchemaSimpleType. I can construct the necessary simple type and use a case statement to do the mappings myself. I was hoping their might be a standard framework class that can either constr...
Recently in a previous project I came across a peculiar difference between VB.NET and C#. Consider the following C# expression which: null <= 2 This expression evaluates to False which is what I would expect. Then the corresponding VB.NET expression: Nothing <= 2 I was surprised to learn that this expression actually evaluates to ...
Is there any tutorial on compiling C lib with Pure MSIL Common Language Runtime Support (/clr:pure) with VS? (VS10) (eg x264 lib) ...
Can we compile C library as .Net dll (containing and opening access to all C libs functions) by just compiling cpp project containing code like extern "C" { #include <library.h> } with /clr:pure argument with VS? (VS10) Or we should do something more trickey? ...
How you use technique described here to work with C structures from .Net? Ofcourse I need a code example - on 3 parts: C declaring parts, C++ wrapping around C and C# acsessing. So what I wonder Is C structture A has as one of its params structure B which consists of at least 2 types one of which is pointer to some variable C which ...
Given: ASP.Net application which uses a legacy COM library legacy COM library which is built without Unicode (MBCS) Windows 2008 dev server on which it all runs Needed: support web app users in different locales Test: 1) I set the system locale on the server to Russian and tested Russian inputs. .NET treats them as UTF16, passes o...
Is CLR loaded and initialized everytime, when a new managed application is loaded and there is a managed application already present? e.g. If on my machine, application "TestApp" is running and after that I start another application "DemoApp". In this case, wiill CLR be loaded again for DemoApp? Or it will use the same one which is load...
Hi, I have a question concerning type constructors within a Value type. This question was inspired by something that Jeffrey Richter wrote in CLR via C# 3rd ed, he says (on page 195 - chapter 8) that you should never actually define a type constructor within a value type as there are times when the CLR will not call it. So, for example...
Why isn't the SSE2 enhanced instruction set optimization available for C++ programs compiled with the /clr switch? ...
I have a rather convoluted scenario where I want to create a DynamicMethod that's attached to a class in an in-memory AssemblyBuilder. The dynamic method calls a method "GetReplacement" in a (regular) assembly of mine. This worked fine in .NET 2.0, but in .NET 4.0 I get an error: MethodAccessException: Attempt by security transparent m...
I am terribly annoyed by the inaccuracy of the intrinsic trig functions in the CLR. It is well know that Math.Sin(Math.PI)=0.00000000000000012246063538223773 instead of 0. Something similar happens with Math.Cos(Math.PI/2). But when I am doing a long series of calculations that on special cases evaluate to Math.Sin(Math.PI/2+x)-M...
I've reduced this issue to, with Visual Studio 2005, in Release mode: Create a new Windows Forms app Change to /CLR Check that the default Form1 runs Add one static library (which itself is linked with BLAS.lib, clapack.lib, libf2c.lib) Then I compile and link and get error LNK2019: unresolved external symbol MAIN_ referenced in...
Hi All, Just curious about how .NET CLR handles interfaces internally? Q1] What happens when CLR encounters something like : simple interface example. (same used below.) interface ISampleInterface { void SampleMethod(); } class ImplementationClass : ISampleInterface { // Explicit interface member imp...
If I have a 2.0 CLR assembly (pure managed code, no mixed mode issues) that I need to link to from a 4.0 CLR Application, does the 2.0 code run on the 2.0 CLR or 4.0. Basically, is there any risk of 4.0 breaking changes affecting the 2.0 code? ...
I need a way to track instances of various classes, without those classes having any knowledge that they are being tracked. Essentially, I have a class factory which creates instances and hands them off to another thread. Once that thread completes and unloads the instance, I need to get notified of that so I can do reference counting an...
I'm a .NET developer by day, but have been playing with Haskell in my spare time for awhile now. I'm curious: any Haskell .net implemenations in the same vein as IronPython? ...
Does the .NET's Virtual Machine compiles the CIL bytecode (and then execute the code at the lowest level - CPU assembler), or it is an interpreter (that reads the following instructions and execute them) ? ...
I want to use CLR table-valued function in SQL Server 2008, which accesses a database from inside itself. I've got a permission exception. I am trying to execute function as the same user as under which it was created. So cause of the problem is not clear.. Here is the function: public partial class MyClass { [SqlFuncti...
I've been doing a bit of investigative work into .NET 4 side-by-side execution recently and, while I have found out a fair amount, there are still some open questions in my mind. My queries are really around in-process loading of libraries into client applications. If I have a client application that uses v4.0 of the CLR then my underst...
A .NET program is first compiled into MSIL code. When it is executed, the JIT compiler will compile it into native machine code. I am wondering: Where is these JIT-compiled machine code stored? Is it only stored in address space of the process? But since the second startup of the program is much faster than the first time, I think th...
