Description
Technical field
The present invention relates to computer application field, particularly relate to the method and system of a kind of PPT of control.
Background technology
PPT (Power Point) is one of office software series significant components of MS's product (also having Excel, Word etc. in addition); The most frequently used is exactly to be used for making lantern slide; Be a kind of PowerPoint graphic package, this software is that powerful PowerPoint is made software; But assisting users alone or the eternal visual effect of online establishment; It has strengthened the multimedia support function, utilizes the manuscript of this software development, can play through different modes; Yet when playing PPT,, cause the top of PPT or the zone that black is arranged at the bottom because machine resolution is different; In addition; Yet when playing PPT, also need carry out other operation sometimes, as changing PPT resolution, change PPT file page setup, open the PPT annotations and comments, closing operation such as PPT annotations and comments.
The mode of traditional operation PPT mainly contains two kinds, a kind ofly realizes the simulation to keyboard through hardware, realizes being similar to the operation of keyboard, but the method can't operate PPT targetedly, and if PPT lose focus, this method also can lose efficacy; A kind ofly in addition realize PPT is operated through the pure software mode, as increase on PPT through software layer of transparent layer, send KeyEvent through software keys then; Let up and down page turning of PPT, can on this hyaline layer, draw and remove simultaneously, yet this mode function is more single; Generally be to carry out page operations (through sending keyboard message) up and down to PPT; Software operation simultaneously needs training, takes time and effort, and also increases memory consumption in addition; And in the process of playing PPT, have shelter, perhaps might block.
On the whole, prior art mainly is to come the operation to PPT with simulating keyboard, and mode is single, perhaps on PPT, increases the layer of transparent layer and annotates and comments on, and consumes unnecessary internal memory, and inconvenient operation.
Summary of the invention
To the shortcoming and defect of above-mentioned prior art, it is a kind of under the situation of the PPT that does not influence current broadcast that the present invention provides, and that can realize not having the interface carries out the method and system of the control PPT of some automation mechanized operations to PPT.
The object of the invention is realized through following technical scheme:
A kind of method of controlling PPT; In the EFI of client computer, be provided with the said client background service module of client background service module that is used for that PPT is controlled and receive the instruction that is arranged on the outside hardware adaptor transmission of client computer, and after the instruction that receives transmission, carry out following steps:
The client background service module obtains current in progress PPT through the API of PPT;
The client background service module is operated current in progress PPT according to the instruction of obtaining.
A kind of system that controls PPT, the hardware adaptor that comprises client background service module among the EFI that is arranged on client computer, communicates with the client background service module of client computer, wherein:
Said hardware adaptor is used for instructing to the transmission of client background service module;
Said client background service module is used for that the API through PPT obtains current in progress PPT after the instruction that receives the hardware adaptor transmission, and according to the instruction of obtaining current in progress PPT is operated.
Scheme according to the invention described above; The present invention operates in progress PPT through hardware adaptor and client background service module; Its main operator scheme is through sending the client background service module behind the hardware adaptor trigger message to; The client background service module obtains current in progress PPT through the API of PPT, and according to the information of obtaining current in progress PPT is operated.
