showing a dialog at keypress

[reachb4]

I am trying to show a dialog at key press like intellisense. i have written the following code inside the keyboard hook function.

if(wParam== WM_KEYDOWN)
		{
		KBDLLHOOKSTRUCT* kbd =((KBDLLHOOKSTRUCT*)lParam);
			
				TCHAR sz[50]={0};
		     	POINT caretPosition;
			    GUITHREADINFO thrInfo;
			    thrInfo.cbSize = sizeof(thrInfo);
			::GetGUIThreadInfo(0,&thrInfo);
			caretPosition.x = (int)thrInfo.rcCaret.left ;
			caretPosition.y = (int)thrInfo.rcCaret.bottom ;
			ClientToScreen(thrInfo.hwndCaret,&caretPosition);

		if ((kbd->vkCode==VK_RIGHT)) 
        {
           
			if (!m_pModeless){
			   m_pModeless = new CMfcDialog();
			}
			
			CWnd* pcWnd=0;
			pcWnd= CWnd::FromHandle(thrInfo.hwndCaret);
		   CRect rct;
				if (!::IsWindow(m_pModeless->GetSafeHwnd()))
				{
	
			
			m_pModeless->Create(IDD_DIALOG1,pcWnd);

			m_pModeless->GetWindowRect(&rct);
			
			m_pModeless->SetWindowPos(CWnd::FromHandle(HWND_TOPMOST),caretPosition.x,caretPosition.y,rct.Width(),rct.Height(),SWP_NOACTIVATE);
			
		    
			m_pModeless->ShowWindow(SW_SHOW);
		

		}
		else{
			CWnd* oldWnd = m_pModeless->SetParent(pcWnd);
			m_pModeless->GetWindowRect(&rct);
			
			pcWnd = CWnd::FromHandle(thrInfo.hwndCaret);
			
			m_pModeless->MoveWindow(caretPosition.x,caretPosition.y,rct.Width(),rct.Height());

			m_pModeless->SetForegroundWindow();
			


		 }

I am not able to bring the window second time at the cursor position and also the window is not displaying as SWP_NOACTIVATE.

Please advice,

Regards and thanks,
John.
