I'm wrapping unmanaged C++ classes using the standard managed C++ approach.
i.e. a __gc class that contains an internal pointer to an unmanaged class.
The purpose is to generate a .NET class library from our unmanaged class
library.

Is a long in managed c++ a 64-bit number like in C#
If so how can I distinguish between that and one that's in some unmanaged code, and therefore that is 32-bit
Call it an int

Can managed C++ be trusted to handle the garbage collector correctly in the
right bit if I have a project with unmanaged and managed parts in it?

   Basic question here, I think-- how do I tell the compiler where to look
for static library files?  I'm trying to compile some apps using DirectX 9,
and VC++ can't find the .lib file needed.  In VC++ 6 I could set the paths
for where to look for them, but in VC .Net I only seem ...

I'm working on a series of projects, all of which have some fundamental things in common.  Those common elements are abstracted into a form which the projects inheret from.  I started a new project, and added ParentForm.cs to it via the Solution Explorer.  (Right Click -> Add -> ...

I am getting the following when compiling mfc application in VS .net
#error Security Issue: The connection string may contain a password
// The connection string below may contain plain text passwords and/or

Anybody notice that while debugging, excel (and some other apps) have a
"hard time" opening?  Anybody know why this is?
"hard time" - takes 20 seconds to open, low CPU usage.
I'm using VC++ .net/2003/7.1, native code.

I have an unmanaged pointer to a class that I want to hold in a managed
class. I pass the pointer (from unmanaged code) in the constructor of the
managed class, and at that point it has value. It is stored in a member
variable in my managed class declared as MyObj __nogc* pMyObj. ...

I have a macro that can determine the number of elements in an array type.  It is defined as follows
#define ARRAY_SIZE_NOGC(x) (sizeof(x) / sizeof(x[0])
This works with unmanaged array types, but not with pointers, since the size of a pointer is always the same and not the size of ...

I have a dialog which contains a tree & list Control. On clicking, of tree item, the list ctrl list changes.
The list ctrl has 2 fields(Name & Value) & is of 'Report' Type.
The list ctrl data is filled from Objects of a class CMyCLass which consists of Members -Name & Value

Hello, I'm writting an application using mixed mode with C++ and
C++.NET, and I have a problem, if I put a breakpoint or try to enter
(with step by step) into a virtual and unmanaged method, the debugger
tell me: "There aren't source code avalaible for the current location",

I am trying to write an unmanaged C++ program using
VS.NET 2003. Its giving some errors. So, my question is
can we write unmanaged code in C++. This is the program I
wrote. Can you suggest me some material which I can refer

would it be possible to sort of engineer some sort of preprocessor macro
that does a 'for' loop.
i.e. for where you would normally use a normal for loop, but when it is
known ay compile time whay the variable is, hence unrolling the loop.

In the file settings for one of the .cpp files in a Win32 unmanaged DLL project, the runtime library it is using by default is Multithreaded Debug. Is there any point in using multithreaded library if it isn't multithreaded DLL? Or does it need this to support multiple clients at ...

   when using _strrev to reverse a string, does it actually go through and
pick up each character in turn and put it to the new position, or does it do
some clever pointer arithmetic meaning it doesn't take longer? the longer
the string is? I'm afraid I have no knowledge of machine ...
