Note that you are getting really lucky by using memcpy to copy into the string object's buffer - that is generally not the correct way to get data into or out of a real object.

CEdit *pEdit = static_cast<CEdit *>( GetDlgItem( IDC_THE_EDIT_BOX ) );
int iLength = pEdit->GetWindowTextLength();
pEdit->SetSel( iLength, iLength );
