-- 求助 自动编号问题
帮助中有按工程代码和制单日期自动编号,其代码是按月自动编号,如何修改成按年自动编号?
Select e.DataCol.Name
Case
"制单日期","工程代码"
If e.DataRow.IsNull("制单日期")
OrElse e.DataRow.IsNull("工程代码")
Then e.DataRow("单据编号") = Nothing
Else
Dim d As
Date = e.DataRow("制单日期")
Dim y As
Integer =
d.Year
Dim
m As
Integer = d.Month
Dim Days As
Integer =
Date.DaysInMonth(y,m)
Dim fd As
Date = New Date(y,m,1) \'获得该月的第一天
Dim ld As
Date = New Date(y,m,Days)
\'获得该月的最后一天
Dim bh As
String = e.DataRow("工程代码") & "-" & Format(d,"yyyyMM") &
"-"
\'生成编号的前缀
If e.DataRow("单据编号").StartsWith(bh) = False
\'如果单据编号前缀不符
Dim max As
String
Dim idx As
Integer
Dim flt As
String flt = "工程代码 = \'"& e.DataRow("工程代码")
& "\' And 制单日期 >=
#" & fd & "# And 制单日期 <=
#" & ld & "# And [_Identify]
<> " & e.DataRow("_Identify") max = e.DataTable.Compute("Max(单据编号)",flt) \'取得该月的相同工程代码的最大单据编号
If max > "" Then
\'如果存在最大单据编号 idx = CInt(max.Substring(12,4)) + 1
\'获得最大单据编号的后四位顺序号,并加1
Else idx = 1
\'否则顺序号等于1
End
If e.DataRow("单据编号") = bh & Format(idx,"0000")
End
If
End
If End
Select

如下
Select e.DataCol.Name Case "制单日期","工程代码" If e.DataRow.IsNull("制单日期") OrElse e.DataRow.IsNull("工程代码") Then e.DataRow("单据编号") = Nothing Else Dim d As Date = e.DataRow("制单日期") Dim y As Integer = d.Year Dim fd As Date = new Date(y, 1, 1) Dim ld As Date = new Date(y, 12, 31) Dim bh As String = e.DataRow("工程代码") & "-" & Format(d,"yyyy") & "-" \'生成编号的前缀 If e.DataRow("单据编号").StartsWith(bh) = False \'如果单据编号前缀不符 Dim max As String Dim idx As Integer Dim flt As String flt = "工程代码 = \'"& e.DataRow("工程代码") & "\' And 制单日期 >= #" & fd & "# And 制单日期 <= #" & ld & "# And [_Identify] <> " & e.DataRow("_Identify") max = e.DataTable.Compute("Max(单据编号)",flt) \'取得该月的相同工程代码的最大单据编号 If max > "" Then \'如果存在最大单据编号 idx = CInt(max.Substring(bh.Length,4)) + 1 \'获得最大单据编号的后四位顺序号,并加1 Else idx = 1 \'否则顺序号等于1 End If e.DataRow("单据编号") = bh & Format(idx,"0000") End If End If End Select
