Thanks guyz for helping. I have found a the solutions. The below code would solve my problem. BOOL MyPropPage::PreTranslateMessage(MSG* pMsg) { if( pMsg && (pMsg->message == WM_KEYDOWN)) { if (pMsg->wParam == VK_TAB) { CWnd* pNextControl = GetNextDlgTabItem(GetFocus(), (GetKeyState( VK_SHIFT ) & 0x8000)); if (pNextControl) GotoDlgCtrl(pNextControl);//pNextControl->SetFocus(); } } return CPropertyPage::PreTranslateMessage(pMsg); } Praveen

thanks for the quick reply. But the problem here is that I do not have know who has logged in and what is his password. For CreateProcessWithLogonW, we need the username and the password. I thought of using CreateProcessAsUser. But there also I do not know how to get the token that represents the user. If you could help me in giving some piece of code, I would be greatful. Thanks again! Praveen
