clr

I'm performing some data type conversions where I need to represent uint , long , ulong and decimal as IEEE 754 double floating point values. I want to be able to detect if the IEEE 754 data type cannot contain the value before I perform the conversion. A brute force solution would be to wrap a try-catch around a cast to double looking for OverflowException . Reading through certain of the CLR documentation implies that some conversions just silently change the value without any exceptions. Is there any fool proof way to do this check? I'm looking for completeness over ease of implementation.

I have some question which puzzled me for a long time. What is the relationship between CLR and one process created by OS? What steps the CLR is loaded when we double-click an "Console Application" or "Windows Forms Application"? I found two methods: _CorExeMain() and _CorBindToRuntimeEx(). What's the role of them? Please see Hosting the Common Language Runtime , Loading the Common Language Runtime into a Process , _CorExeMain Function , CorBindToRuntimeEx Function . I think the basic answer is, the CLR must run in a process (host). If you "double-click", a process is created (initally purely

I'm using this class: public ref class x: public System::Windows::Forms::Form { private: gcroot<std::string> name; } and i am getting the following error: IntelliSense: a member of a managed class cannot be of a non-managed class type I know i can use char* , but if I use lots of char* i will have to manually do the delete[] or some heap corruption issues will rise I've been stuck on this for two days now note: I have to use c++ and have to use UI in c++ That's the wrong usage for gcroot<>, you only need that if you keep a reference to a managed object in an unmanaged class. In this case you

I'm doing a presentation in few months about .Net performance and optimization, I wanted to provide some samples of unnecessary optimization, things that will be done by the compiler anyways. where can I find some explanation on what optimizations the compiler is actually capable of maybe some before and after code? check out these links C# Compiler Optimizations compiler optimization msdn Also checkout this book on MSIL 1. Microsoft Intermediate Language: Comparison Between C# and VB.NET / Niranjan Kumar What I think would be even better than examples of "things that will be done by the

I am wondering about Marshal.GetFunctionPointerForDelegate. Namely I want to know how it converts a delegate to a function that is non static into a function pointer. Does it dynamically generate a code stub that has the instance attached somehow? And if so, doesn't this leak memory? Perhaps the delegate frees it in its finalizer? It doesn't look like System.Delegate has a finalizer, so I am very interested in how this mechanism works. I would assume that it would take 4 bytes for the function pointer and 4 bytes for the instance (on 32-bit), yet it returns a simple IntPtr. Big question,
