Share Functions
The share functions control shared resources. A shared resource is a local
resource on a server (for example, a disk directory, print device, or named pipe)
that can be accessed by users and applications on the network. The share
functions are:
NetShareAdd
| Shares a resource on a server.
| NetShareCheck
| Queries whether a server is sharing a device.
| NetShareDel
| Deletes a share name from a server's list of shared resources.
| NetShareEnum
| Retrieves share information about each shared resource on a server.
| NetShareGetInfo
| Retrieves information about a specified shared resource on a server.
| NetShareSetInfo
| Sets a shared resource's parameters.
|
The WNetEnumResource function should be used instead of the NetShareEnum function, which is obsolete.
The NetShareAdd function allows a user or application to share a resource of a specific type
using the specified share name. The NetShareAdd function requires the share name and local device name to share the resource.
A user or application must have an account on the server to access the
resource.
You may also specify a Security Descriptor to be associated with a share,
which specifies which users will be allowed to access files through this share, and
with what type of access.
LAN Manager defines three types of special share names for interprocess
communication (IPC) and remote administration of the server:
- IPC$, reserved for interprocess communication.
- ADMIN$, reserved for remote administration.
- A$, B$, C$ (and other local disk names followed by a dollar sign), assigned to
local disk devices.
Share functions are available at four information levels:
SHARE_INFO_0
SHARE_INFO_1
SHARE_INFO_2
SHARE_INFO_502
The following information levels are valid only for NetShareSetInfo:
SHARE_INFO_1004
SHARE_INFO_1006
The following is supported only on Windows NT:
SHARE_INFO_1501
For NetShareSetInfo, parmnum values refer to the members of the SHARE_INFO structure, as follows. These
values are used when indicating an error in a specific parameter through parm_err.
parmnum value
| Member of SHARE_INFO structure
| SHARE_NETNAME_PARMNUM
| shi_netname
| SHARE_TYPE_PARMNUM
| shi_type
| SHARE_REMARK_PARMNUM
| shi_remark
| SHARE_PERMISSIONS_PARMNUM
| shi_permissions
| SHARE_MAX_USES_PARMNUM
| shi_max_uses
| SHARE_CURRENT_USES_PARMNUM
| shi_current_uses
| SHARE_PATH_PARMNUM
| shi_path
| SHARE_PASSWD_PARMNUM
| shi_passwd
| SHARE_FILE_SD_PARMNUM
| shi_security_descriptor

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
