High-level profile APIs (PROFILE object)
|
|
|
|
The PROFILE class contains a higher-level interface to the
|
|
UserProfile APIs. It is meant solely for use by WINNET. All WINNET
|
|
modules should use the PROFILE APIs rather than going directly to
|
|
the UserProfile APIs. Applications other than WINNET will have to
|
|
use the UserProfile APIs.
|
|
|
|
The PROFILE class adds the following to the basic UserProfile APIs:
|
|
|
|
- Establishes connections as specified in profile, including
|
|
prompting for password
|
|
|
|
- Displays error popups as appropriate during profile load
|
|
|
|
Note that the UserProfile APIs which the PROFILE class accesses
|
|
use access global variables. For this reason, it never makes sense
|
|
to have more than one PROFILE object, and it is generally not
|
|
desirable to have a PROFILE object of other than global scope.
|
|
|
|
Those PROFILE APIs which take an HWND parameter may give control to
|
|
Windows or call Windows APIs, but those which do not take an HWND
|
|
parameter will never do either. Thus, of the exported APIs, only
|
|
PROFILE::Load is liable to compact memory.
|
|
|
|
Several PROFILE methods take a UINT *puWnErr parameter in order to
|
|
return an auxiliary WN_ error code. In these cases, the following
|
|
combinations of error codes are possible:
|
|
Return code: Auxiliary: Meaning
|
|
NERR_Success WN_SUCCESS Operation was successful
|
|
NERR_Success WN_CANCEL Operation cancelled, error
|
|
already displayed
|
|
NERR_Success WN_CONTINUE Error occurred, error
|
|
already displayed
|
|
<other> <other> Error has not been displayed
|
|
|
|
|
|
|
|
PROFILE::Init
|
|
|
|
Initializes the PROFILE object. Call this before calling any other
|
|
PROFILE method. Call this method while in the (DS register) context
|
|
of the shell rather than the context of any application.
|
|
|
|
Return Values:
|
|
NERR_Success Success
|
|
ERROR_NOT_ENOUGH_MEMORY Out of memory
|
|
|
|
|
|
PROFILE::Free
|
|
|
|
Releases the PROFILE object. Call this after calling all other
|
|
PROFILE methods.
|
|
|
|
Return Values:
|
|
NERR_Success Success
|
|
|
|
|
|
PROFILE::Load
|
|
|
|
Loads one device connection from the user profile, or loads all
|
|
device connections from the user profile. Also returns an advisory
|
|
parameter indicating whether the connection was cancelled, or
|
|
whether some error has already been reported; note that the return
|
|
code is NERR_Success if the dialog is cancelled.
|
|
|
|
Return Values:
|
|
NERR_Success Success
|
|
ERROR_NOT_ENOUGH_MEMORY Out of memory
|
|
other Misc. net error
|
|
|
|
|
|
|
|
PROFILE::Query
|
|
|
|
Asks about a specific connection in the user profile.
|
|
|
|
If PROFILE::Query returns NERR_Success, the other fields are valid.
|
|
|
|
sResourceType is one of the values of field use_info_1.ui1_arg_type.
|
|
|
|
sResourceName_Type is one of the values of field use_info_2.ui1_res_type.
|
|
|
|
Return Values:
|
|
NERR_Success Success
|
|
NERR_UseNotFound Connection not in profile
|
|
ERROR_NOT_ENOUGH_MEMORY Out of memory
|
|
other Misc. net error
|
|
|
|
|
|
|
|
PROFILE::Enum
|
|
|
|
Lists all connections in the user profile. This list appears as a
|
|
list of null-terminated strings with NULL-NULL at the end, e.g.
|
|
|
|
D:\0G:\0LPT1\0E:\0\0
|
|
|
|
The list is in no defined order. Pass only a valid pointer to a
|
|
BUFFER object.
|
|
|
|
If PROFILE::Enum returns WN_SUCCESS, the bufDeviceList field is valid.
|
|
|
|
Return Values:
|
|
NERR_Success Success
|
|
ERROR_INSUFFICIENT_BUFFER The pbufDeviceList buffer is too small.
|
|
ERROR_NOT_ENOUGH_MEMORY Out of memory
|
|
other Misc. net error
|
|
|
|
|
|
|
|
PROFILE::Change
|
|
|
|
Saves a connection into the user profile, or removes a connection
|
|
from the user profile. PROFILE::Change will prompt the user
|
|
before creating a new profile entry.
|
|
|
|
If cnlsResourceName.strlen() == 0, PROFILE::Change will remove an
|
|
existing profile entry.
|
|
|
|
sResourceType is one of the values of field use_info_1.ui1_arg_type.
|
|
|
|
usResourceName_Type is one of the values of field use_info_2.ui1_res_type.
|
|
|
|
Return Values:
|
|
NERR_Success Success
|
|
ERROR_NOT_ENOUGH_MEMORY Out of memory
|
|
other Misc. net error
|
|
|
|
|
|
|
|
PROFILE::Remove
|
|
|
|
Removes a <device,remote> association from the profile. If the
|
|
given device is associated with a different remote name than the
|
|
one passed as a parameter, this method does nothing but return
|
|
success.
|
|
|
|
This method is intended to be used in disconnect operations.
|
|
Then, if the the profile contained a previously unavailable device,
|
|
which was left in the profile when a new connection was established
|
|
on top of the unavailable device, the profile will be unchanged.
|
|
Thus, the previously "covered" or "hidden" unavailable device, now
|
|
becomes what the local device is "connected" to again.
|
|
|
|
cnlsDeviceName is the local device name in the <device,remote> pair.
|
|
|
|
cnlsResourceName is the remote name in the <device,remote> pair. This
|
|
name is typically that DEVICE::QueryRemoteName returns before
|
|
DEVICE::Disconnect is called.
|
|
|
|
|
|
Return Values:
|
|
NERR_Success Success
|
|
other Misc. net error
|
|
|
|
|
|
|
|
PROFILE::MapNetError
|
|
|
|
Miscallaneous utility routine to help convert an NERR_ error code
|
|
to a WN_ error code.
|
|
|
|
|
|
|
|
PROFILE::DisplayChangeError
|
|
|
|
Displays an error popup for a failure to change the profile. This
|
|
routine should only be used for SYS and NET error codes, not for IERR
|
|
error codes.
|
|
|
|
|
|
PROFILE::DisplayLoadError
|
|
|
|
Displays an error popup for a failure to load some connecion in the
|
|
profile. This routine should only be used for SYS and NET error codes,
|
|
not for IERR error codes. If you pass fAllowCancel then the user will
|
|
also be able to press a cancel button. If they did press cancel, then
|
|
*pfDidCancel will be TRUE, otherwise *pfDidCancel will be FALSE. Note
|
|
it is only valid to check pfDidCancel if fAllowCancel is TRUE.
