Solution with 2 projects does not compile

I have a solution with two projects. In the first project, I have Frame and some controls, in the second - CForcesEditorDialog: CDialog. I want to compare them. But this error does not allow me to compile the project:

MainFrame.obj: error LNK2019: unresolved external character "public: __thiscall CForcesEditorDialog :: CForcesEditorDialog (class CWnd *, class MainFrame *)" (?? 0CForcesEditorDialog @@ QAE @PAVCWnd @@ PAVMainFrame @@@ Z) link : int __thiscall MainFrame :: OnCreate (struct tagCREATESTRUCTA *) "(? OnCreate @MainFrame @@ IAEHPAUtagCREATESTRUCTA @@@ Z)

class CForcesEditorDialog;

class MainFrame : public CFrameWnd
{
    CForcesEditorDialog* forcesEditorDialog;    

public:
    MainFrame();    
    ~MainFrame();   
    //virtual void CreateChildControls( void );
    //afx_msg void OnMouseMove(UINT, CPoint);

protected:
    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
    DECLARE_MESSAGE_MAP()
};

int MainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    forcesEditorDialog = new CForcesEditorDialog(this,this);//CForcesEditorDialog(this,this);   
}




class CForcesEditorDialog : public CDialog
{
    //For including ForcesBar
    ForcesBar* m_forcesBar;
    MainFrame* pMainFrame;
public:
    CForcesEditorDialog(CWnd* _pParentWnd = NULL, MainFrame* _pMainFrame = NULL);   // standard constructor
}

CForcesEditorDialog::CForcesEditorDialog(CWnd* _pParentWnd, MainFrame* _pMainFrame)
: CDialog(IDD_CUR_DIALOG, _pParentWnd),
      p_expander    (0),
      p_selectedItem(0),
      m_enabled     (false)
{
    m_forcesBar = new ForcesBar();
    pMainFrame = _pMainFrame;
}

Perhaps I had a problem with enabling these projects. I have never had a solution with two projects. Do you have any ideas about this?

CForcesEditorDialog? dll?

If it is dynamic, you will need to export the functions and classes from the DLL that you want to use in your exe. This guide mentions exports: http://www.codeguru.com/cpp/cpp/cpp_mfc/tutorials/article.php/c4017/MFC-DLL-TUTORIAL-PART-1.htm

From AFX_EXT_CLASS. You would use it in your class declaration to export it from your DLL, for example:

class AFX_EXT_CLASS CForcesEditorDialog : public CDialog
{
