Are you calling it after the call to base class CDialog::OnInitDialog(); ?

It should be something like

BOOL YourDialog::OnInitDialog()
{
CDialog::OnInitDialog();

m_DeviceList.Create
( WS_VISIBLE | LBS_NOINTEGRALHEIGHT | WS_VSCROLL | WS_HSCROLL |
WS_TABSTOP,
CRect(7,10,241,168),
this,
IDC_LIST1
);

return TRUE;
}

I've just found that i don't need to call "Create" in my application before
using other methods of CListBox like AddString.

Thank you anyway.
