| System.IO.Stream from IStream? (2 replies) |

| Hi all, Currently the system I've been working on for the past 5 years uses OLE structured storage (Microsoft's Compound File implementation) to persists it's data. We have some automation object that we wrote in ATL that delegate everything to IStorage and IStream. What I need to do now is somehow hook up the IStream interface to the System.IO.Stream class.

| microsoft.public.dotnet.languages.vc |
| Hello , I am wondering if there is any function like GetHashCode for Managed C Application? In unmanaged c code this pointer value can be used as a hash code but in managed code there is no pointer value. C# and VB.NET provides a function Object.GetHashCode which can be possibly used for identifying an object. Any suggestion? Thanks Maneesh |

| Building a custom NET control using Managed Extensions (6 replies) |
| microsoft.public.dotnet.languages.vc |
| Hi, Did anyone try to create a custom NET control using Managed Extensions? Any success? It seems pretty straightforward but the problem I found that I can not use this control in WinForms designers (I mean I can not put this control on the form in design time). Similar simplest (a few line of code) control written using C# works fine. Did I miss some special settings (compiler switches, class/ass... |

| Hallo, I'd like to use a C# assembly in a VC7 program. It works in general, but the VC application is quite large (written in VC6, but now converted) and makes heavy use of std::string. The C# functions return System::String, and I would like a nice and fast conversion from System::String to std::string. At the momemt, I'm copying the System::String character per character to a char[] buffer and c... |

| Dispatch tables with functions containing managed pointers (5 replies) |
| microsoft.public.dotnet.languages.vc |

It is a requirement that the functions accept at least one argument that is a pointer to a managed object. The following program illustrates the problem: #using mscorlib.dll #include tchar.h using namespace System; gc class Managed { public: int I; }; int Func(Manag... |

| VC7 pointer regression (2 replies) |
| microsoft.public.dotnet.languages.vc |
| Here's an odd one... if I name one of my variables "main" (wmain is my entry point), I can't assign a pointer. It just points to a random place in memory. Well, random to me at least. Even happens if I pass the pointer to a function, that doesn't use "main" at all. It's like the linker is doing something "smart", though it happens in DEBUG, with no optimization. My example, works great with VC6, w... |
