Hi,
I have a DLL that exposes interfaces (compiled with VC++ 6.0)
I've used exported functions(not interfaces) of this DLL in a .NET project and everything is alright.
The problem is that the built assembly (exe) do not expose the interfaces of my DLL, thing that it is done automatically in a native C++ project.
Can anyone helps??
Regards.

Error After Compiling: please help
I have a C++ solution in Visual Studio 2008
This solution contains two projects:
1- Native DLL that communicate with others delegates and provides interfaces to the second project
2-Managed C++ that use the functions of the first project (exe) that represent the interface of a server.
I compile the solution and there's no problem.
When I connect a client all thing are alright. But when I... -

problem with visual C++ 9 compile
Well the problem is so frustrating for a any C++ developer
I want to import call using this syntax
#include.....
class Imported;
class NEWclass
{
Imported* imp;
}
the compiler considers "class Imported " as a new definition for the class Imported.
Can anyone show me a way to import the class without calling the header file.... -
in the header file, we should add the key word inline to the functions that are implemented in the header.Leave a comment:

Sorry,
but the problem was so simple I've just use two different call conventions __stdcall
and __cdlecLeave a comment:

Any Idea about this error? Value of ESP
I am writing COM servers and each time I have this error I don't know the cause:
Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.
I want to have a detailed explanation of this error and the problems that cause it

Hi pootle,
thx for your clear ideas.
but I don't understand the last part of your reply, anyway I have CLR exceptions enabled in my debugger.Leave a comment:

In my case the debugger can't step into the code when it attends the statement where the callback(that I defined) try to change the text of the label.
Now I understand more the problem, in winforms we cannot change the controls from an extern process(extern to the one that created the control)
==>an exeption is raised but don't don't block the execution, but the debugger return to the top of the callback

Well I understand that the problem is a cross-thread exception
So, please tell me how can I fix this problem without changing the structure of my application.Leave a comment:

variantchangetype problems COM interoperability C++/CLI
hi,
I'm writing a wrapper from unmanaged C++ to C++/CLI
I've replaced the variant_type by
a structure:
Type_Value
{
SupportedTypes Type,
String^ Value
}
Supported_Types //enm type
{
types written in hand
}
well, this is working very good and this is suitable for me
but now I need the results of variantchangety pe cuz I'm developping... -
well I have a good idea but I don't think is the best:
//in managed code
func1(Type^ tn);
but in the dllimport I put this function
extern void func1(cli::inte riorptr<Type> tn);
this code works but I want a best solution, so please helpLeave a comment:

Is there a mean to pass Pinny Pointer to native code?
As the title of the question show I want to pass a pinny pointer (C++/CLI) pointer to a native function
When Compiling there's no error
but the pointer do not contain any value
I explain more the problem:
typedef value struct //defined in managed code
{
}Type_Name;
The same Type is defined in a native DLL but without the keyword value
