    namespace and class..help!

    this is my CDlg32.cpp
    Code:
    #include <windows.h>
    #include "CDlg32.h"
    
    namespace Joel {
    	class CDlg32 {
    	private:
    		HINSTANCE hInstancia;
    		HWND hDlg;
    		int nDLG;
    	public:
    		CDlg32();
    		~CDlg32();
    	protected:
    	};
    }
    Now, CDlg32.h:
    Code:
    #if !defined(_CDLG32_H)
    #define _CDLG32_H
    
    CDlg32::CDlg32() : hInstancia(NULL), hDlg(NULL), nDLG(0) {}
    
    #endif
    Now main.cpp
    Code:
    #include <windows.h>
    #include "CDlg32.h"
    
    using Joel::CDlg32;
    
    int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd) {
    	return 0;
    }
    Returns this errors.

    CDlg32.h(6) : error C2653: 'CDlg32' : is not a class or namespace name

    It looks like the code in CDlg32.cpp should be in CDlg32.h

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    And code that is in the CDlg32.h should be in the cpp
    To be or not to be == true
