Embodiment Construction

[0035] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0036] see figure 1 Shown, for the realization of the present invention such as figure 1As shown in the structural diagram of the cash register software data extraction system, this example includes a window access module and a screen access module. The computer captures data through the data extraction system. The data extraction system includes a window access module and a screen access module. The cash register system (member marketing system) communicates with user terminals (mobile phones, etc.) through the network communication system to deduct fees. The present invention can be applied to the cash register system based on windows message and Hook mechanism. When it is necessary to grab the data of a certain cash register software on the market, such as the total price, according to the characteristics of t...

Abstract

The invention discloses a cashier system docking method based on windows messages and a Hook mechanism. Data displayed on cashier software are captured through a window access method based on Microsoft Windows message circulation and a screen access method based on Hook technology. The method comprises the following steps: dragging a sight bead program to obtain screen coordinates and client arearelative coordinates, calling the coordinates and parameters to realize switching of screen access or collaborative access, carrying out fetching to obtain docking data, and then filtering, analyzingand extracting the docking data. According to the invention, the data extraction of the cashier software is carried out by adopting a mode of combining multiple modes, so that the cashier software with multiple models and sizes is supported, and the operation of extracting the data of the cashier software is simple, rapid and accurate.

Description

technical field [0001] The invention relates to the technical field of Internet cash register, in particular to a data extraction system for docking integrated system platforms with different cash register software. Background technique [0002] Software often needs to be connected to other software for the purpose of upgrading or function expansion. During the docking process, the docking software needs to obtain some data of the docked software. In the cashier software, the traditional docking method is mainly through the docker calling the API provided by the receiving bank software, or by introducing related hardware devices such as smart POS machines. Although These docking methods can also achieve program docking to a certain extent, but these methods have low versatility and compatibility, and may require additional hardware devices. Secondary operations are required, so these docking methods often not only increase the workload for operators but also put forward hig...
