-- [求助]自动输入列数据
表中的列为报告日期 和报告编号，现通过输入日期自动产生编号，但同一日期可能有多份编号不能重复怎么实现啊
If 
e.DataCol.Name = "报告日期" Then
If e.DataRow.IsNull("报告日期") Then
e.DataRow("报告编号") = Nothing
Else
Dim d As Date = e.DataRow("报告日期")
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 = Format(d,"yyyy.MM") \'生成编号的前6位,4位年,2位月.
If e.DataRow("报告编号").StartsWith(bh) = False \'如果编号的前6位不符
Dim max As String
Dim idx As Integer
max = e.DataTable.Compute("Max(报告编号)","报告日期 >= #" & fd & "# And 报告日期 <= #" & ld & "# And [_Identify] <> " & e.DataRow("_Identify")) \'取得该月的最大编号
If max > "" Then \'如果存在最大编号
idx = CInt(max.Substring(7,3)) + 1 \'获得最大编号的后三位顺序号,并加1
Else
idx = 1 \'否则顺序号等于1
End If
e.DataRow("报告编号") = "FX." & bh & "-" & Format(idx,"000")
End If
End If
End If
e.DataCol.Name = "报告日期" ThenIf e.DataRow.IsNull("报告日期") Then
e.DataRow("报告编号") = Nothing
Else
Dim d As Date = e.DataRow("报告日期")
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 = Format(d,"
yyyy.MM") \'生成编号的前6位,4位年,2位月.If e.DataRow("报告编号").StartsWith(bh) = False \'如果编号的前6位不符
Dim max As String
Dim idx As Integer
max = e.DataTable.Compute("Max(报告编号)","报告日期 >= #" & fd & "# And 报告日期 <= #" & ld & "# And [_Identify] <> " & e.DataRow("_Identify")) \'取得该月的最大编号
If max > "" Then \'如果存在最大编号
idx = CInt(max.Substring(7,3)) + 1 \'获得最大编号的后三位顺序号,并加1
Else
idx = 1 \'否则顺序号等于1
End If
e.DataRow("报告编号") = "FX." & bh & "-" & Format(idx,"000")
End If
End If
End If

1、前缀的规则是什么？根据什么确定前缀？
2、
idx = CInt(max.Substring(11,3)) + 1 \'获得最大编号的后三位顺序号,并加1
改成
idx = CInt(max.Substring(bh.length,3)) + 1 \'获得最大编号的后三位顺序号,并加1
