Abstract
Methods and arrangements are provided for use in multiple user computing environments. These methods and arrangements can be configured to allow for a plurality of separate and concurrent desktops and workspaces within the shared computing environment. One method includes creating a separate desktop thread for each user that is authenticated during a logon process, creating a separate desktop associated with each desktop thread, and maintaining a list of desktop threads that are created. In this manner, several users can be logged on simultaneously. In certain implementations, the method further includes establishing a separate user environment associated with each desktop and launching a separate user shell associated with each desktop. The list of desktop threads allows for selective and/or automatic switching from a first desktop to a second desktop without terminating a desktop thread associated with the first desktop. The methods and arrangements are also applicable to remote process logon and switching.
Description
The application is dividing an application in the Chinese patent application No.00815798.7 of being entitled as of submitting on July 26th, 2000 " sharing provide in the computing environment a plurality of parallel desktops and the method and apparatus of workspace ".

Embodiment
As shown in fig. 1, computing machine 20 comprises: one or more processors or processing unit 21; A system storage 22; With a bus 23, this bus will comprise that each system's ingredient of system storage 22 is connected with processor 21.In bus 23 several bus structure of expression (comprising arbitrary bus-structured processor or local bus in the various bus structure of memory bus or Memory Controller, peripheral bus, AGP and employing) any one or multiple bus structure.
System storage comprises ROM (read-only memory) (ROM) 24 and random access memory (RAM) 25.Store basic input/output (BIOS) 26 among the ROM 24, this system contains basic routine, is used for such as transmission information between each unit that helps between the starting period at computing machine 20.
These drivers and relevant computer-readable medium thereof provide the non-volatile memories of computer-readable instruction, data structure, program module and other data for computing machine 20.Although environment for example as described herein has used hard disk, interchangeability disk 29 and interchangeable CD 31, yet, those of skill in the art are to be understood that, in the operating environment of giving an example, the stored data computing machine readable media of the addressable other types that can also use a computer, such as, magnetic tape cassette, flash memory cards, digital video disk, random access memory (RAM), ROM (read-only memory) (ROM) etc.
Some program modules can be stored among hard disk, disk 29, CD 31, ROM 24 or the RAM 25, and these program modules comprise operating system 35, one or more application program 36, other program modules 37 and routine data 38.The user can by such as the input equipment of keyboard 40 and pointing device 42 to computing machine 20 input commands and information.Other input equipment (not shown) can comprise microphone, operating rod, game mat (game pad), satellite dish antenna (satellitedish), scanner etc.These input equipments and other input equipments are connected with processing unit 21 by the interface 46 that links to each other with bus 23.
The display device of monitor 47 or other types also connects by the Interface ﹠ Bus 23 such as video adapter 48.Except monitor, personal computer also comprises other peripheral output device (not shown) usually, such as loudspeaker and printer.
In the time of in being applied to the LAN networked environment, computing machine 20 is connected with local network 51 by network interface or adapter 156.In the time of in being applied to the WAN networked environment, computing machine 20 generally includes a modulator-demodular unit 54 or other devices, is used to set up the communication on the wide area network 52 (such as the Internet).Can be that built-in or external modulator-demodular unit 54 is connected with bus 23 by interface 46.In networked environment, can be stored in the remote memory storage device at personal computer 20 described program modules or its part.It is exemplary that network shown in should be appreciated that connects, and can also adopt other modes to set up communication link between the computing machine.
Below with reference to Fig. 2, a graphic user interface of giving an example (GUI) used when there is shown the user who is suitable for discerning the operating system that signs in to computing machine 20 shows.Here, show a logon screen 100, it has first header area 102 of a sign logon screen 100.Logon screen 100 can occupy all over the screen of display 47 or its part.As shown in the figure, first header area 102 can comprise any graphic feature (for example, bitmap, photo, image, literal etc.).
In this example, show second header area 106 at the left side edge place of logon screen 100.Here, to identify this computing machine be " Den Commputer " in second header area 106.In addition, also provide an optional shutdown unit 108, made the user can turn off computing machine.
As an example, logon screen 100 is to supplying a plurality of independent and the whole bag of tricks of usefulness desktop that walks abreast and workspace in the shared computing environment of computing machine 20 and the starting point that device is described.As detailed in the following and shown in the process flow diagram of Fig. 3-4, realized a kind of desktop switching scheme, used for WindowsTM NT of Microsoft or WindowsTM 2000.But, those of skill in the art can recognize that this desktop switching scheme is also applicable to other operating systems, computing machine etc.For example, this scheme extends at this and comprises that also WinStation switches, and wherein each can comprise equally that all desktop switches.
Here the implementation of giving an example that is proposed is utilized multipad DLL (dynamic link library) (API) general among the Windows NT, for each sets up independent workspace by the user that logon screen 100 carries out interactive login.Utilize the configuration file (profile) of Windows NT, user's data can be different from other user's data, and, according to the user's or the preference of computer management device, can protect visit to other user's data.Utilize the independent desktop of each user, a plurality of users are log into thr computer simultaneously.Switch because this is a desktop, therefore, can switch the user soon.Because application program is moved in the environmental baseline of desktop and separation fully each other, therefore, can not lose Application Status between transfer period.
If the user leaves computing machine just under the situation of not protecting its workstation, so, for the login sessions of protecting the user is avoided other users' influence, after the wait period that can be provided with by the user, operating system is got back to the login desktop with automatic switchover.The login desktop can be avoided the influence of user's desktop, and, only after utilizing identity verification entity in the operating system to confirm the user, just can switch and get back to user's desktop.
For this reason, with reference to the process flow diagram among Fig. 3.Here, process 200 shows logon screen 100 from computing machine.In step 202, the user provides the input of necessity so that login as the part of subscriber authentication scheme.For example, the user selects textual identifier 110 or graphical identifier 112 to enter password in password input field 114 then.Authentication process itself is carried out in operating system, shown in determination step 204.If checking is unsuccessful, so corresponding step 204 (denying), process 200 is returned logon screen 100.If be proved to be successful, so corresponding step 204 (being), process 200 proceeds to determination step 206.
In determination step 206, whether the user that determining step 204 is verified logins.This desktop tabulation (ODL) 208 that opens by inspection realizes.If judge user's not login (denying) as yet of being verified through step 206, so, according to step 210, for this user sets up a new desktop thread.Then, in step 214, clue and DESKTOP INFORMATION are added in the user's who is logined in ODL 208 up till now the tabulation.This user's clue can also be set up user environment in step 216, and starts the user's shell on its newly-built desktop in step 218.In step 220, logging program switches to user's new desktop 222.So far, login process finishes.
Turn back to determination step 206, if opened for this user's desktop, as shown in the relevant clauses and subclauses among the ODL 208, step 206 (being) makes process 200 proceed to step 224 so.In step 224, switch to existing desktop thread, subsequently, in step 220, switch to suitable desktop 222.Among Fig. 3, N＞1 desktop is arranged, represented with desktop 222a-c.
Below with reference to Fig. 4, the process 240 of desktop 222 is nullified in the flowcharting among the figure.In this example, for the user provides three kinds of " cancellation " modes.First kind of mode carried out in step 242, and at this, the user nullifies intentionally fully.When this Logout Events occurring in step 242, so, in step 244, this desktop is eliminated, and ODL 208 is updated, and clue is terminated.After step 244, process 240 turns back to logon screen 100.
In the step 246, for the user provides the second way of carrying out " cancellation ", at this, the user is switched desktop with manual type.In any moment before cancellation, the user can (for example by user input) carry out an operation, and this operates under the situation of the advisory user's clue that will not nullify it is turned back to logon screen 100.Like this, user's desktop keeps operation, and all application programs that started on this desktop continue operation.But, the user can't see any content of these application programs, and this is because its desktop is hidden in fact.At this moment, claim that desktop is " killed ", but it is still activation.The user need login once more according to process 200 desktop of activation " is opened ".
In the step 248, show the third mode that the user can nullify, at this, dormant state period that the user can be provided with (for example not having the input of mouse movable or keyboard) later, operating system will be thought user's shut-down operation computing machine at present, so it gets back to logon screen 100 with automatic switchover.When they seem when no longer using a computer, by protection user's desktop, this will help to improve security.For other users, this also makes their the easier session that uses a computer and needn't worry to finish another user.
In addition, can also in sharing computing environment, provide a plurality of independent and parallel environment by switching remote process such as WinStation rather than switching desktop.Logically, WinStation has comprised a plurality of desktops.For each user sets up WinStation and in certain user login or switch and switch the WinStation that activates when getting back to logon screen 100 and can realize mechanism same as described above.
Although some in the whole bag of tricks of the present invention shown in the drawings and the device preferred embodiment, and these embodiments have been described in above detailed description, yet, be to be understood that, the present invention is not limited to the disclosed embodiment that these are given an example, under the prerequisite of the spirit of the present invention of in the appended claims book, stating and stipulating, can there be many kinds to reconfigure, revise and replace.
