Embodiment 1

[0052] Forms realized according to the VO-based form customization configuration and parsing operation method proposed by the present invention are usually in the form of middleware, and their use and operation depend on other systems or platform environments. This example describes the business form in the process of initial registration of house property rights [new house] in the workflow-based e-government platform as an embodiment.

[0053] This example uses Windows XP SP3 as the operating system environment, Visual Studio 2005 as the development environment, c# as the development language, the open source SourceGrid control as the basis of the form display control, and oracle 10g as the background database.

[0054] Such as figure 1 Shown is a structural diagram of a form application embodiment. VO-based workflow-oriented form customization and configuration and parsing and running method, which includes the following three parts:

example ID

[0339] 2) In order to query the data of the main table and sub-table based on VO, it is necessary to implement the data access layer for VO. The main interfaces are as follows: Figure 6 As shown. According to the form instance ID, MAINTABLEVOLIST and SUBTABLEVOLIST, use the interface object LoadMainTableData(object keyValue, string mainTableVO, string mainTableDLLPath) and ArrayList LoadSubTableData(objectforeignKeyValue, string subTableVO, string subTableDLLPath) to query the main table and subtable data, if the query result is not Empty, loaded into the main table VO object list and sub-table VO object list;

[0340] 3) Query the form customization information in the database GRID_TEMPLATE table according to the form ID, and initialize the form. Read the number of rows and columns in GRID, initialize a blank form, read and instantiate the customized information of each cell in turn, if the current cell is not configured with VO field information and is not a calculated fiel...

Abstract

The invention provides a value object (VO)-based form customization, configuration and parsing operation method, comprising three technical links including VO entity class generation, form design and form operation. The method is characterized by reading database dictionary table information and automatically generating VO entity class corresponding to the primary table and the subtable of the database; during form design, using a form editor to customize the pages, associating the form cells with the fields in the VO entity class, storing the form customization information in the form of files or databases, configuring the read-write and printing accesses of the form cell by setting interface parameters and storing the configuration information; and during form operation, using a form parsing engine to read and parse the form customization and configuration information defined during design, dynamically generating the form object with access control, reflecting the correction of the value of the form cell to the VO and transferring the correction to a data source via the VO, thereby realizing addition, deletion and correction operations of the data.

Description

technical field [0001] The invention relates to the field of electronic forms, in particular to the generation of VO entity classes, form customization and configuration at design time, form analysis and operation at runtime, and the like. Background technique [0002] At present, a large number of business forms are involved in software such as e-government and e-commerce. The business forms in traditional software are generally realized by hard coding. The interface design and database reading and writing related to business forms are cumbersome and time-consuming. Moreover, the hard-coded form cannot meet the frequently changing user and business needs. When the business changes, the code must be modified and adjusted by the programmer, which is inefficient and subject to more restrictions. [0003] In order to solve the above problems, it is necessary to extract the functions related to the business form, and provide customized configuration and parsing operation mode, s...
