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:

Code:
ClassLibrary2a^ class1a = gcnew ClassLibrary2a;

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


Code:
namespace test_window_application {

	using namespace System;
	using namespace System::ComponentModel;
	using namespace System::Collections;
	using namespace System::Windows::Forms;
	using namespace System::Data;
	using namespace System::Drawing;
	using namespace ClassLibrary2a;


	/// <summary>
	/// Summary for Form1
	///
	/// WARNING: If you change the name of this class, you will need to change the
	///          'Resource File Name' property for the managed resource compiler tool
	///          associated with all .resx files this class depends on.  Otherwise,
	///          the designers will not be able to interact properly with localized
	///          resources associated with this form.
	/// </summary>
	public ref class Form1 : public System::Windows::Forms::Form
	{
	public:
		Form1(void)
		{
			InitializeComponent();
			//
			//TODO: Add the constructor code here
			//
		}

	protected:
		/// <summary>
		/// Clean up any resources being used.
		/// </summary>
		~Form1()
		{
			if (components)
			{
				delete components;
			}
		}
	private: System::Windows::Forms::Button^  button1;
	protected: 

	private:
		/// <summary>
		/// Required designer variable.
		/// </summary>
		System::ComponentModel::Container ^components;

#pragma region Windows Form Designer generated code
		/// <summary>
		/// Required method for Designer support - do not modify
		/// the contents of this method with the code editor.
		/// </summary>
		void InitializeComponent(void)
		{
			this->button1 = (gcnew System::Windows::Forms::Button());
			this->SuspendLayout();
			// 
			// button1
			// 
			this->button1->Location = System::Drawing::Point(78, 116);
			this->button1->Name = L"button1";
			this->button1->Size = System::Drawing::Size(75, 23);
			this->button1->TabIndex = 0;
			this->button1->Text = L"button1";
			this->button1->UseVisualStyleBackColor = true;
			this->button1->Click += gcnew System::EventHandler(this, &Form1::button1_Click);
			// 
			// Form1
			// 
			this->AutoScaleDimensions = System::Drawing::SizeF(6, 13);
			this->AutoScaleMode = System::Windows::Forms::AutoScaleMode::Font;
			this->ClientSize = System::Drawing::Size(284, 262);
			this->Controls->Add(this->button1);
			this->Name = L"Form1";
			this->Text = L"Form1";
			this->ResumeLayout(false);

		}
#pragma endregion
	private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
				 //ClassLibrary2a^ class1a = gcnew ClassLibrary2a::Class1;
				 ClassLibrary2a^ class1a = gcnew ClassLibrary2a;
				 

			 }
	};
}


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:ata;
using namespace System:iagnostics;
using namespace System::IO;


Code:
namespace ClassLibrary2a {

	public ref class Class1
	{
		// TODO: Add your methods for this class here.
		public: void MyMethodNew() {
			// Do something in the method
			//ContactsControl^ contact = gcnew ContactsControl();
			//contact->label1->Text = "hello chris";
			MessageBox::Show("message", "title");
		}
	};

	
}

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.
