Plantage Windows sur ouverture fenetre modale sous visual c++

Comme d'habitude, tu es 1 peu flou .

Montre nous ton code, tes déclarations/initialisations de variables.

Voila mon code :
class Contact : public CDialog
{
// Construction
public:
Contact(CWnd* pParent = NULL); // standard constructor


// Dialog Data
//{{AFX_DATA(Contact)
enum { IDD = IDD_CONTACT };
CString m_StrRichEdit_Europe;
//}}AFX_DATA


// Overrides
// ClassWizard generated virtual function overrides
//{{AFX_VIRTUAL(Contact)
protected:
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support
//}}AFX_VIRTUAL

// Implementation
protected:

// Generated message map functions
//{{AFX_MSG(Contact)
virtual void OnOK();
virtual void OnCancel();
virtual BOOL OnInitDialog();
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
};

//{{AFX_INSERT_LOCATION}}
// Microsoft Visual C++ will insert additional declarations immediately before the previous line.

#endif // !defined(AFX_CONTACT_H__D15AFB87_F122_48D0_90DD_C55998BDDB75__INCLUDED_)

void CCineTransDlg:nHelpContact()
{
// TODO: Add your command handler code here
Contact HelpContact(GetParent()); // Affichage de la boite de dialogue HELPABOUTCINETRANS
HelpContact.DoModal();

}
