TWS Api - connection problem

I tried to program an application interacting with TWS in C++ using the TWS Api from interactive brokers.

If I run my program and try to connect TWS recognizes my connection attempt (a message box appears asking me wheter I want to connect or not) but immediately after my application crashes, every time.

Here is the part I try to subclass EWrapper (in AutobotDlg.h)

Code:

class CAutobotDlg : public CDialog, public EWrapper
{
// Konstruktion
public:
	CAutobotDlg(CWnd* pParent = NULL);	// Standardkonstruktor

// Dialogfelddaten
	enum { IDD = IDD_AUTOBOT_DIALOG };

	protected:
	virtual void DoDataExchange(CDataExchange* pDX);	// DDX/DDV-Unterstützung


// Implementierung
protected:
	HICON m_hIcon;

	// Generierte Funktionen für die Meldungstabellen
	virtual BOOL OnInitDialog();
	afx_msg void OnSysCommand(UINT nID, LPARAM lParam);
	afx_msg void OnPaint();
	afx_msg HCURSOR OnQueryDragIcon();
	//IB
	afx_msg void OnConnect();
//...	afx_msg void OnMarketScanner();
	//IB end

	DECLARE_MESSAGE_MAP()

	//IB
	void tickPrice( TickerId ddeId, TickType field, double price, int canAutoExecute);
// ... 
	void fundamentalData(TickerId reqId, const CString& data);
	//IB end

public:
	afx_msg void OnBnClickedButton1();

private:
	EClient     *m_pClient;

};

Then I override the functions in AutobotDlg.cpp which includes AutobotDlg.h:

Code:

void CAutobotDlg::tickPrice( TickerId ddeId, TickType field, double price, int canAutoExecute)
	{
	
	}
//...
void CAutobotDlg::fundamentalData(TickerId reqId, const CString& data)
	{

}

And tried to connect with the following peaces also in AutobotDlg.cpp:

Code:

CAutobotDlg::CAutobotDlg(CWnd* pParent /*=NULL*/)
	: CDialog(CAutobotDlg::IDD, pParent)
{
	m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
	//Klient erstellen
	m_pClient = new EClientSocket(this);
}

void CAutobotDlg::OnBnClickedButton1()
{
	m_pClient->eConnect("127.0.0.1",  7496, 0);
}

It would be very great if someone could help me, really thank you! I added some of the source files and the executable.
