This is a very simple shared folder manager that allows you to shared folders by
dragging and dropping them onto a tree control.
Using the control
Drag a folder from an Explorer window over the tree control to create a new share. The folder will be shared without
any control regarding advanced user rights. If the folder is already shared, or you have no rights, or other error occured, an error
message will appear. (Keep in mind that the code is NOT very tested - being only a sample -, was developed on Windows2000/MSVC++ 6.0 SP3, and is
managing only the local machine. You have to browse the network, fill a combo - or list box - and read currently selected machine from it.)
All is done by implementing the interface
IDropTargetShare, and especially the
IDropTargetShare::Drop method. This implementation send
WM_DROPFILES message to parent dialog, where
let you identify the number of dropped items, their names, and calls for each
NetShareAdd loaded from netapi32.dll.
After that, you can simply call in your
OnCreate, if you do not use dialogs MDI child windows, for example):
m_lpDropTarget = new IDropTargetShare;
HRESULT hr = RegisterDragDrop(m_treeShare.m_hWnd, m_lpDropTarget);
RevokeDragDrop revokes the OLE drag-drop registration. Pay attention to
OleInitialize call performed in
CWinApp override to ensure at least a chance for
RegisterDragDrop. After that, the interface is responsable with drag and drop. Error handling could be enhanced,
but you get the point.
The tree creation uses a thread routine to fill items. Here is used a structure called
typedef struct _tagSHAREINFO
TCHAR lpszMachineName[_MAX_PATH + 1];
} SHAREINFO, *LPSHAREINFO;
The structure members have, I think, quite self-explanatory names. The events are used to intercept, using
OnClose dialog events to terminate the
The deleting of a shared folder is nothing more than a normal using of
TVN_BEGINDRAG tree control notification used in conjunction with
WM_LBUTTONUP and a boolean flag (
m_fDragging) to switch states between ON|OFF dragging states.
MultipleShowWindowByDlgId routine helped a lot setting the miriad of statics - it is no more that a simple use of
variable-arguments functions. You could use the static control simple manipulation in the About dialog as a simple replacement for Chris Maunder's
hyperlink control (to send me an e-mail message).
