正确显示数据库里同时存在的GB码和BIG5码:
Public Function CheckBIG(strSource As String) As Boolean
Dim idx As Long
Dim ByteTemp() As Byte
CheckBIG = False
For idx = 1 To Len(strSource)
ByteTemp = StrConv(Mid(strSource, idx, 1), vbFromUnicode)
If UBound(ByteTemp) > 0 Then
If (ByteTemp(1) >= 64) And (ByteTemp(1) <= 126) Then
CheckBIG = True
Exit For
End If
End If
Next idx
End Function
判断偶数和奇数:
要真说出来哪一个函数能够做得到,还真难。但我们可用下面的代码来进行识别,返回
“假”即偶数,返回“真”则奇数:
function Is_odd(num) as boolean
n=num mod 2
if n=1 then
Is_odd=true
else
Is_odd=false
end if
end function
把一长串数字分位显示:
<%
Function Comma(str)
If Not(IsNumeric(str)) Or str = 0 Then
Result = 0
ElseIf Len(Fix(str)) < 4 Then
Result = str
Else
Pos = Instr(1,str,".")
If Pos > 0 Then
Dec = Mid(str,Pos)
End if
Res = StrReverse(Fix(str))
LoopCount = 1
While LoopCount <= Len(Res)
TempResult = TempResult + Mid(Res,LoopCount,3)
LoopCount = LoopCount + 3
If LoopCount <= Len(Res) Then
TempResult = TempResult + ","
End If
Wend
Result = StrReverse(TempResult) + Dec
End If
Comma = Result
End Function
%>
<html>
<body>
<%
aLongNumber = "12345678"
%>
原来的数字: <%=aLongNumber%><br/>
用逗号格式化后: <%=Comma(aLongNumber)%>
</body>
