There was a book which presented a DOS compatible operating system, but I think it's out of print. However, you could look here[^] where you can download a copy of the FAT32 specification from Microsoft. Steve S Developer for hire

Thanks i will definitely read that book Thanks and regards Harshal shete

You can call any function you have access to from your thread. Write a cleanup function and call it? Are you thinking along the lines of InitInstance/ExitInstance virtual initialization/cleanup methods?

maybe you can reverse use the sock.sin_port after the connection has been occured with port = ntohs(sock.sin_port) from the socket.

By using the CBS_DROPDOWN or CBS_SIMPLE style, there will be an edit control as part of the combobox. If you do not want this, you must use the CBS_DROPDOWNLIST style instead.

I think instead of TrackPopupMenu(..., pTreeCtrl->m_hWnd, ...); you should try TrackPopupMenu(..., m_hWnd, ...); I hope this helps.

void CTreeViewDlg::OnNMRclickTree1(NMHDR *pNMHDR, LRESULT *pResult) { CPoint ptMouse; DWORD dwPos; UINT nFlags; CTreeCtrl *pTreeCtrl; pTreeCtrl = (CTreeCtrl *)GetDlgItem(IDC_TREE1); { dwPos = ::GetMessagePos(); ptMouse.x = LOWORD (dwPos); ptMouse.y = HIWORD (dwPos); CPoint ptAction = ptMouse; // convert coordinates pTreeCtrl->ScreenToClient(&ptAction); // determine if click is on tree item HTREEITEM hItemRClick = pTreeCtrl->HitTest(ptAction, &nFlags); // if click is on tree item, if (hItemRClick != NULL) { // set selection to right+clicked item pTreeCtrl->SelectItem(hItemRClick); HMENU hMenu = LoadMenu(AfxGetInstanceHandle(),MAKEINTRESOURCE(IDR_MENU1)); if(hMenu) { hMenu = GetSubMenu(hMenu,1); if(hMenu) { TrackPopupMenu(hMenu,0,ptMouse.x,ptMouse.y,0,pTreeCtrl->m_hWnd,NULL); } } } } *pResult = 0; } i have done something like this Noe the pop up menu is poping up but whenever i click on something it does not go to respective handler!! Thanks and regards Harshal

Check the WM_CONTEXTMENU is called for your tree control. then check the point where right clicked (lParam value has the point)has any item,.. the handle to the tree will be passed in wParam if so then check it is leaf node (by checking its child you can find out). Show your context menu and handle occrdingly.. Hope this'll help... Do your Duty and Don't expect the Result

Can you explain what do you need exactly? WhiteSky

There's nothing special to it. You can use normal file handling routines. Just like how you write a file to your hard disk. Nobody can give you wiser advice than yourself. - Cicero

But Apart from this i have another query i am doing undo redo also. it is working fine but in undo as well as redo there is one small problem that whenever i undo/redo then after every undo/redo operation it selects some text and then on next undo/redo it undoes/redoes the character that was typed. how i can fake the middle selection between two operations?? undo code is like this if (m_rich.CanUndo()) { m_rich.Undo(); } Thanks and regards Harshal

complete answer:) WhiteSky

You may check whether the DEL key is pressed in the OnKeydown() If it is pressed then store the edit box content in a string variable. After that call the CWnd::OnKeydown() Rinu Raj

yes thank's anshuman actually i am doing multilevel undo redo thanks and regards Harshal

From the 'serial port reader' thread I would place the data into a thread-safe queue of some sort and notify the 'display' thread that new data is available. The 'display' thread can pull it out of the queue and format as appropriate. Any sufficiently gross incompetence is nearly indistinguishable from malice.
