pos机固件怎么导出(上位机外挂报表第3课---完结篇)

前面2课叙述了如何准备数据---将数据写入数据库，如何查询、导出和打印日报表。

对于月报表、年报表的操作其实同日报表一样，只是需要做一个系统后台程序，将数据库的每天/每月的数据进行计算，然后写入数据库的月表单和年表单即可。

对于月报表和日报表的界面可以参考设计如下：

对于后台运行程序设计代码如下：

Const g_conString = " Provider=MSDASQL.1;Persist Security Info=False;Data Source=SQL_KEP;Initial Catalog=SQL_KEP" '链接数据库

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Private Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
