In addition, the first user program can obtain the object code of the second window from the second computer host 144 directly through the network 130, and is not limited. Similarly, the second client program obtains the object code of the first window through the remote management device 110 or the network 130, so that the second computer host 144 can control the first application executed on the first computer host 142. In step S240, after the client program obtains the control of the application, it further detects the change of the window corresponding to the application to perform an instant update. Referring to Figure 2B, a flow chart of a window update in accordance with a preferred embodiment of the present invention is shown. In step S242, the user program obtains the object code of the window. In step S244, the user program maps the window to the window surface. In step S245, the client program determines if the window has moved. If so, in step S246, the coordinates of the window are calculated and the desktop is updated accordingly. In step S247, it is determined whether there is a change in the content of the window. If so, in step S248, the desktop is updated based on the changed content. • The second computer host 144 is taken as an example for explanation. After the second client program executed by the second host computer 144 obtains the object code of the first window 310, the first window 310 is mapped to the desktop 300. At the same time, the second user terminal program determines whether the first window 310 has been moved or whether the content of the first view window 310 has changed. If the first window 310 is moved, the second client program calculates the coordinates of the first window 310 after being moved and updates the desktop 300 accordingly. If the content of the first window 310 changes, the second client program updates the desktop 300 according to the changed content. The remote management system 100 can also include more user-side programs to 201106166, iw) 4y/pA 1 to facilitate more users to participate in video conferencing or web conferencing. As shown in FIG. 1, the remote management system 100 further includes a third client program, and the third client program is executed on a third computer host 146, and can be networked with the remote management device 110. The communication is to manage the remote management device 110 and control the host computers 122 to 126. The third user program can provide a third window to the desktop, and the third window represents a third application. The third application is actually the application that the third computer host 146 executes and wants to share. In this way, the first user program, the second user program, and the third user program respectively cause the desktop to display the first window, the second window, and the third window at the same time. The third client program obtains the object codes of the first window and the second window through the remote management device 110 or the network 130, so that the third computer host 146 can control the first application and the second application. Referring to Figure 3, there is shown a schematic diagram of an example of a desktop in accordance with a preferred embodiment of the present invention. The user program causes the desktop 300 to display the first window 310, the second window 320, and the third window 330. The first window 310, the second window 320, and the third window 330 respectively display the first application and the second application. The content of the third application. The first window 310, the second window 320, and the third window 330 can be freely dragged. In addition, the desktop 300 can also provide user desktop control functions, such as console 340. Through the console 340, the user can achieve many control functions, such as adding an application, sharing a desktop, managing a label, exiting a share, multiple screen settings, or chatting, without limitation. When the desktop 300 displays too many windows at the same time, the desktop control function enables the partial windows to be displayed on different tabs of the desktop 300, such as tabs 201106166 * 1 w 352 and 354 (ie Tabl and Tab2). So the desktop won't be messy because of too many windows. In addition, the desktop 300 can also be displayed on multiple displays of the host computer. Taking the first computer host 142 as an example, if the first computer host 142 corresponds to three displays, the desktop 300 can be simultaneously displayed on three displays. In addition, multiple windows can be displayed on three displays through the multi-screen setting function. For example, the first window 310 is displayed on the first display corresponding to the first computer host 142, and the second φ window 320 and the third window 330 are simultaneously displayed on the second display and the third corresponding to the first computer host 142. The display is not limited in the present invention, and depends on the needs of the user. Alternatively, the first display is used to view the desktop of the first computer host 142 itself, and the second or third display is used to view the virtual desktops formed by other computer host applications. Furthermore, a single computer host is not limited to sharing only one application. The first computer host 142 is taken as an example. The first user program can provide a fourth window 360 to the desktop 300, and the fourth window represents a fourth application. The fourth application is actually another application that is executed by the first computer host 142 and is to be shared. The first user program causes the desktop 300 to simultaneously display the first window 310, the second window 320, the third window 330, and the fourth window 360. In this way, users can share multiple applications to discuss with other conference participants, which makes the conference more efficient. The remote management apparatus and method disclosed in the above embodiments of the present invention have π 201106166 ..
