Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention
Formula is further described.
Please refer to Fig.1, the embodiment provides a kind of lantern slide control of authority to play new method, including following step
Suddenly：
S1：Slide file is converted into slide pictures；
S2：The authority list that the host is submitted is received, the authority list includes the sensitive page page number in the slide pictures,
And the sensitive page is corresponding plays account and playing duration；
S3：When the host plays the slide pictures, current page slide pictures are transmitted to server；
S4：The server transport current page slide pictures to the slave plays, wherein the server is according to quick
After the sense page page number judges current page slide pictures for sensitive page, the slave is according to corresponding broadcasting account and playing duration
Determine playing duration.
Further, the slide file is converted into slide pictures by OfficeToImage functions.
Further, the mode of the host broadcasting slide pictures is：The host reads in the lantern slide figure
Piece is simultaneously shown in label.
Further, when the playing duration is 0, the slave cannot play the slide pictures.
Further, the authority list that the host is submitted submits authority list after by verification.
Further, the slave controls reproduction time by thread timing.
Further, the slave is played the slide pictures and is realized by using function PPTDispalyClient.
The embodiment of the present invention also provides a kind of lantern slide control of authority play system, including authority distribution module and projection
Module,
Authority distribution module, the authority list submitted for receiving the host, the authority list include the lantern slide figure
The sensitive page page number in piece, and the corresponding broadcasting account of the sensitive page and playing duration, the specific work(of authority distribution module
Can be as follows：
Function 1.1, when organizer clicks to enter associated rights by the host and sets, first asks to return to server
All online users, server will be by the way that when being connected with slave, server will after on the slave by authentication by user
The thread SerConClientThread being connected with the slave by addClientThread (String uid,
SerConClientThread ct) be put into hashmap and manage, when the host send AskOnLine data packets to it is described from
When machine asks online user, thread is deposited by getAllOnLineUserid () function Iterator traversals
Hashmap obtains all online users and sends it to the host；
Function 1.2, organizer are entered after sensitive page sets the page by the host, select sensitive page number, after the completion of visitor
Data packet containing sensitive page is sent to server by family end, and server is by sensitive page write into Databasce；
Function 1.3, organizer enter the priority assignation page by the host, are filled in the authority list of corresponding user
User corresponds to the playing duration of sensitive page, and playing duration cannot show that editor completes for the sensitivity page in 0 corresponding client
Authority form is sent to server by client afterwards, server by form write into Databasce,
Module is shown, for slide file to be converted into slide pictures, the host plays the slide pictures
When current page slide pictures are transmitted to server, the server transport current page slide pictures are to described from machine sowing
