Hi all,
I need your help.I am working on a class library project using c++ to create the function that I want to use to call the function from my windows application.
When I try this:
I am getting the errors:
C2882: 'ClassLibrary2a' : illegal use of namespace identifier in expression
C2065: 'class1a' : undeclared identifier
C2061: syntax error : identifier 'ClassLibrary2a'
I have added the ClassLibrary2a dll in the reference but it have make no different as I am still getting the same errors.
Here is my form code:
#pragma once
Here is the ClassLibrary2a code:
// ClassLibrary2a.h
#pragma once
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;
using namespace System::Data;
using namespace System::Diagnostics;
using namespace System::IO;
I dont really understand why I am getting the errors as it doesn't make any sense. I have included the `using namespace ClassLibrary2a` but it have make no different. I am using managed c++/cli
Do you know why I am getting the errors?
Do you know how I can fix it?
I have tried everything included the namespace and added in the reference but it have make no different. I couldn't be able to find out myself how to resolve it.
Any advice would be much appreciated.
