请教老师下面的自动编号编码需要怎么修改，编号出不来
If e.DataCol.Name = "编制日期" AndAlso e.DataCol.Name = "合同性质_一单一招" AndAlso e.DataCol.Name = "合同性质_年度合同" AndAlso e.DataRow("工作联系单编号") = Nothing Then
If e.DataCol.Name = "编制日期" Then
If e.DataRow.IsNull("编制日期") Then
e.DataRow("工作联系单编号") = Nothing
Else
If e.DataRow.IsNull("编制日期") = False AndAlso e.DataRow("合同性质_一单一招") = True Then
Dim d As Date = e.DataRow("编制日期")
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,"yyyyMM") '生成编号的前6位,4位年,2位月.
If e.DataRow("工作联系单编号").StartsWith(bh) = False '如果编号的前6位不符
Dim max As String
Dim idx As Integer
max = e.DataTable.SQLCompute("Max(工作联系单编号)","编制日期 >= #" & fd & "# And 编制日期 <= #" & 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(10,3)) + 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("工作联系单编号") ="WX-" & bh & "-" & Format(idx,"000")
e.DataRow.Save
End If
End If
If e.DataRow.IsNull("编制日期") AndAlso e.DataRow("合同性质_年度合同") = True Then
Dim d As Date = e.DataRow("编制日期")
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,"yyyyMM") '生成编号的前6位,4位年,2位月.
If e.DataRow("工作联系单编号").StartsWith(bh) = False '如果编号的前6位不符
Dim max As String
Dim idx As Integer
max = e.DataTable.SQLCompute("Max(工作联系单编号)","编制日期 >= #" & fd & "# And 编制日期 <= #" & ld & "# And [_Identify] <> " & e.DataRow("_Identify")) '取得该月的最大编号

idx = CInt(max.Substring(10,3)) + 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("工作联系单编号") ="ND-" & bh & "-" & Format(idx,"000")
e.DataRow.Save
End If
End If
End If
End If
End If
