Embodiment 1

[0020] Such as figure 1 As shown, implementation 1 of the present invention provides a PPT projection control method for the joint school network teaching system, the method comprising:

[0021] S11. Receive an instruction from the user to show multiple PPT files at the same time, open the corresponding multiple PPT files and automatically enter the show state, each time a PPT file is opened, a corresponding PPT show thread is established, and one of the PPT files is displayed on the display screen File projection interface;

[0022] Specifically, the user selects multiple PPT files to show at the same time or sequentially selects multiple PPT files to show through clicking or touching events. State, it is preferable to use COM components to open PPT files. The COM components include projection components for PPT files in various formats, such as the formats corresponding to PPT files produced by all current versions of OFFICE or WPS. After the COM component receives the requ...

Embodiment 2

[0030] Such as figure 2 As shown, the implementation 2 of the present invention provides a PPT projection control method for the joint school network teaching system. This method is implemented on the basis of embodiment 1, so the repetition is no longer repeated:

Abstract

The invention provides a PPT projection control method for a joint school online education system. The method comprises the following steps: receiving an instruction sent by a user for simultaneouslyprojecting a plurality of PPT files, opening the corresponding PPT files and automatically entering a projection state, correspondingly establishing a PPT projection thread when each PPT file is opened, and displaying a projection interface of one PPT file on a display screen; and when an instruction sent by a user for switching to the projection interface of the next PPT file is received, switching the corresponding PPT projection thread for display, and displaying the projection interface of the PPT file selected by the user on the display screen. According to the invention, a plurality of PPT files can be directly loaded and a projection state can be automatically entered; under the condition that the PPT file in the current projection place is not quitted, switching to the projection interface of the next PPT file can be realized by one key; all operations on the currently displayed PPT file do not affect the showing states of other PPT files, and when two or more PPT files are shown at the same time, explanation can be switched randomly.

Description

technical field [0001] The invention relates to the field of joint school online teaching, in particular to a PPT projection control method used in the joint school online teaching system. Background technique [0002] When teachers use the joint school network teaching platform software to give lectures, when they often need to switch between two or more PPT files, there are two existing implementation methods: a. Through third-party software (OFFICE or WPS) to To show PPT files, only one can be played at a time. If you need to switch to the next one, you must exit the PPT currently being shown before you can show another PPT file. The operation is very inconvenient; b. Parse the PPT file into a picture format. However, all multimedia elements and animation effects in the PPT file will be lost, seriously affecting the teaching effect. Contents of the invention [0003] The purpose of the present invention is to provide a PPT projection control method for the joint school...
