① vb 提取两个最小值
Dim arrList, arrItem
Dim lListCount As Long
Dim i As Long
Dim sStr3 As String
Dim sStr31 As String
Dim iVal3 As Single
Dim iVal31 As Single
Dim iVal4 As Single
Dim iTmp As Single
arrList = Split(Text1.Text, vbCr) '
lListCount = UBound(arrList)
iVal3 = 3.402823E+38
iVal4 = 3.402823E+38
For i = 0 To lListCount - 1
If Len(Trim(arrList(i))) > 0 Then
arrItem = Split(arrList(i), ",")
iTmp = Val(arrItem(2))
If iVal3 > iTmp Then
iVal31 = iVal3
sStr31 = sStr3
iVal3 = iTmp
sStr3 = arrItem(0) & "," & arrItem(1)
End If
iTmp = Val(arrItem(3))
If iVal4 > iTmp Then iVal4 = iTmp
End If
Next
text2.Text = sStr31 & "," & iVal31 & vbCrLf & sStr3 & "," & iVal3 & vbCrLf & iVal4
② VB操作两个数据库，从A数据库表中查询，然后写入B数据库表中！
这个不难
我教你怎么跨数据库（跨服务器都可以）操作多数据表：
新建一个ACCESS，放在VB工程目录下，什么都不要去做，就用到他的一个ODBC功能做桥接，在VB中连接ACCESS数据库照常
我就给个ADO连接ACCESS连接SQL多数据库连接表联合查询两个数据库数据表的例子：
Private Sub 控件名称_事件过程(变量)
Dim A, B as String
'-----------------定义变量来存字符串
Adodc1.ConnectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & App.path & "\ACCESS数据库.后缀"
'-----------------连接ACCESS数据库照常
A="Select 字段1 AS 名称1, 字段2 as 名称2 From 表1 IN [ODBC] [ODBC;Server=SQL Server;uid=用户名;PWD=密码;Server=服务器IP;DataBase=数据库名1] Where 字段3 LIKE %'5555'%"
B="Select 字段8 AS 名称1, 字段9 as 名称2 From 表2 IN [ODBC] [ODBC;Server=SQL Server;uid=2用户名;PWD=密码;Server=服务器IP;DataBase=数据库名2]"
Adodc1.recordsoure= A & "Unoin" & B
Adodc1.Refresh
Set 电子表格.DataSource=Adodc1
End Sub
看到没有？跨了数据库，服务器都可以跨，SQL语句没多大问题吧？我相信，推荐答案那么简单的语句只能解决SQL操作问题。
