适用格式 : XXX-YYYYMMDD-0000
Public Function ZDYBH(StrTable As String, StrField As String, StrBH As String, Optional FDay As String = "YYMMDD", Optional ILen As Integer = 3, Optional B As Boolean = False) As String
'==================================================================
'功能: 自定义用户编号,带断号重号检测功能
'格式: "XXX"-"日期格式 "-"0000"
' StrTable 为任意表名称
' StrField 为任意字段名称
' StrBH 编码类型 , 可自义任意格式
' FDay 日期格式 默认日期格式为:YYMMDD",其他符合FORMAT格式的如 YYYYMM,YYYY,YYYYMMDD
' ILen 为数字格式化长度 , 默认长度为3 代表 000 格式
' B 为是否要检测断号 ,默认为FALSE 不检测
'用法: ZDYBH("产量表", "产量ID", "LDH")
' ZDYBH("产量表", "产量ID", Me.Combo1)
' ZDYBH("产量表", "产量ID", Me.Combo1, "YYYY")
' ZDYBH("产量表", "产量ID", Me.Combo1, , 4, True)
