VB FOR 循环语句
Dim i,j,c As Integer
Dim a,b As String
c = 0
Adodc1.RecordSource = " select * from inf where 下单时间 between #" & DTP1.Value & "# and #" & DTP2.Value & "# "
Adodc1.Refresh
For j = 0 To Combo1.ListCount - 1
b = Combo1.List(j)
For i = 0 To Adodc1.Recordset.RecordCount - 1
a = Adodc1.Recordset.Fields(15).Value
If b = a Then
c = 1 + c
End If
Next i
Text8.Text = Combo1.List(j) + "共" + Str(c) + "记录"
Next j
这里面有一个COMBOBOX控件里面有几个省份的名称（不重复）,一个表中的字段（也就是Fields(15)）也有省份名称（有重复）,现在想统计 这段时间内 表中字段（Fields(15)中）几个省份的名称,结果显示在Text8.text里!如：河南共8条记录,内蒙共3条记录,河南共9条记录……

用count,否则的话,如果记录太多,你将不停地MoveNext,不停地判断b=a.
Dim i As Integer,n As Long,s As String
Text8 = ""
Adodc1.RecordSource = " select 字段15的名称,count(*) from inf where 下单时间 between #" & DTP1.Value & "# and #" & DTP2.Value & "# group by 字段15的名称"
Adodc1.Refresh
For i = 0 To Combo1.ListCount - 1
s = Combo1.List(i)
n = 0
Adodc1.Recordset.MoveFirst
Do While Not Adodc1.Recordset.EOF
If Adodc1.Recordset.Fields(0) = s Then n = Adodc1.Recordset.Fields(1):Exit Do
Adodc1.Recordset.MoveNext
Loop
Text8 = Text8 & "," & s & "共" & n & "条记录"
Next
将上述语句中的“字段15的名称”修改为你数据库中inf表的第16个字段的字段名称.
