用两种不同的方法来求实现数字字符串的最大，最小和平均值（转）

ENABLESESSIONSTATE = False %>
'1. Selecting the numbers from a string:
myString = "2, 4, 6, 8, 10, 12"
aValues = Split(myString, ",", -1, 1)

Function Min(someNumbers)
dblLowestSoFar = Null
For I = LBound(someNumbers) to UBound(someNumbers)
If IsNumeric(someNumbers(I)) Then
　If CDbl(someNumbers(I)) < dblLowestSoFar Or IsNull(dblLowestSoFar) Then
　 dblLowestSoFar = CDbl(someNumbers(I))
　End If
End If
Next
Min = dblLowestSoFar
End Function

Function Max(someNumbers)
dblHighestSoFar = Null
For I = LBound(someNumbers) to UBound(someNumbers)
If IsNumeric(someNumbers(I)) Then
　If CDbl(someNumbers(I)) > dblHighestSoFar Or IsNull(dblHighestSoFar) Then
　 dblHighestSoFar = CDbl(someNumbers(I))
　End If
End If
Next
Max = dblHighestSoFar
End Function

Function Avg(someNumbers)
dblHighestSoFar = Null
For I = LBound(someNumbers) to UBound(someNumbers)
If IsNumeric(someNumbers(I)) Then
　If CDbl(someNumbers(I)) > dblHighestSoFar Or IsNull(dblHighestSoFar) Then
　 dblHighestSoFar = CDbl(someNumbers(I)) + CDbl(someNumbers(I)) /
　End If
End If
Next
Avg = dblHighestSoFar
End Function

'2. Or, selecting the numbers from a database:
Set cnDZ = Server.CreateObject("ADODB.Connection")
cnDZ.Open "DSN=myDatabase"
Set rsLo = cnDZ.Execute("SELECT Min(PRICE) AS loPRICE FROM TBLADS")
Set rsHi = cnDZ.Execute("SELECT Max(PRICE) AS hiPRICE FROM TBLADS")
Set rsAvg = cnDZ.Execute("SELECT Avg(PRICE) AS avgPRICE FROM TBLADS")
%>

1. Selecting the numbers from a string:

The lowest number is:

The highest number is:

The average number is:

2. Selecting the numbers from a database:

The lowest priced ad is:

The highest priced ad is:

The average selling price of these ads is:


cnDZ.Close
Set cnDZ = Nothing
rsLo.Close
Set rsLo = Nothing
rsHi.Close
Set rsHi = Nothing
rsAvg.Close
Set rsAvg = Nothing
%>
