With the dump debugging support in .NET 4.0 we are looking into automatically (after asking the user of course :) creating minidumps of C# program crashes to upload them to our issue tracking system (so that the minidumps can assist in resolving the cause of the crash). Everything is working fine when using the WithFullMemory minidump t...
After seeing and listening lot about Managed and Unmanaged Code , and knowing about the only difference is that Managed is about CLR and un-managed is out side of CLR, it makes me really curious to know in detail , what is it that all about Managed and Un-Managed Code,Memory and Size?

I need to write a method in C# that uses the Exchange Web Services (EWS) Managed API to read emails from a mailbox and given the ItemId/UniqueId of the current email, returns the ItemId/UniqueId of the next email in the inbox after the current email. Furthermore, for various reasons I require the method to be a static stateless method, ...
I want to use WPF in an app. I want to write it in C++. Does the application have to be managed? I know that I can mix managed with unmanaged. I'm wondering if I can have the whole application be unmanaged. ...
I am calling a C# method from C code. The C# method: [UnmanagedFunctionPointer(CallingConvention.Cdecl)] public delegate void p_func(StringBuilder arg); public static void callback(StringBuilder arg) { Console.WriteLine(arg.ToString()); } The C method: extern "C" void c_method(p_func f) { char msg[4]; ...
Alright, I know how you normally would declare a pointer: void SomeFunction(array<float> ^managedArray) { pin_ptr<float> managedArrayPtr = &managedArray[0]; } This works fine except when managedArray contains no elements. In that case, it throws an IndexOutOfRangeException. In C# you can do this: void SomeFunction(float[] managedA...
I hear/read about it sometimes when talking about .NET, for example "managed code" and "unmanaged code" but I have no idea what they are and what are their differences. What are their difference, by definition? What are the consequences of using either of them? Does this distinction exist in .NET/Windows only? ...
Hello, I'm having some troubles debugging a solution which contains both a native ANSI C DLL project and a managed C#/WPF application project. I call the functions exported by the DLL using the LoadLibrary/GetProcAddress Win32 API functions (DllImport attribute is not applicable for my program as the DLL is selected by the user). Both ...

I'm a C++ user and i started a few ago with C#, to be able to use XNA, because it makes really easy working with 2d textures and 3d models, so that i can forget a bit about that and just center in the game code. The problem comes that I'm used to the pointers, so that my way of thinking the code usually makes use of some, and I couldn't...

Hi all, I'm trying to add some managed code into an existing c++ GUI application. I'd like to get a functional callback working...specifically, I'd like to pass a method pointer from UNMANAGED code to MANAGED code and have the managed code invoke the callback. I'm looking at something like this: typedef int (__stdcall *ANSWERCB)(int)...
Hey, I am required to pass some sort of identifier to unmanaged code which then processes a request and calls back into my managed code once it has done some processing. I was wondering whether it would be better to create a GCHandle and pass it to the unmanaged code to then recover the object once the unmanaged code passes the GCHandl...
So, there is a legacy code that has to be imported into .NET projects. Which one do you preffer, and why: packing it into COM module or making small and tight c++ managed wrapper around it There is third option of exporting the functions in the DLL, but let's say that we want classes here. ...
Say I have this C# method: public bool GetVal() { return a1 == b1 || c1 == d1 || GetE1() == GetF1(); // Illustrating complicated logic here.. } I don't want to modify the content of the variables / return values of methods in the statement above, but want to return false to the method that's calling GetVal(). Is it possible to us...

I use COM interop to call functions in a c# dll from my VC6 MFC DLL, and this works fine. I want to call a function to retrieve string values. How do I declare a 'string' in my unmanaged C++? How should the 'string' appear in the c# code? Currently the c# function in the dll takes ref string arguments, and my c# test app works fine, but ...
