请教ASP控制显示字数<%=trim(rs("detail"))%>

Question

请教ASP控制显示字数<%=trim(rs("detail"))%>这个怎么能控制显示的字数，比如内容有100字，这里只显示50个字。

望高手解答，谢谢！
<%=left(trim(rs("detail")),50)%> 这样不行，显示不出内容。

提供你一个超级好用的函数，使用方法
response.write FixString(需要截取的字符串,字符串字节长度汉字算2个,如果被截取添加省略点的个数)
Function FixString(ByVal strWord, ByVal intByteLength, ByVal intPadDotAmount)
        If strWord > "" Then
                If Length(strWord) <= intByteLength Then
                        FixString = strWord
                Else
                        Dim i
                        Dim intLength
                        Dim strChar
                        Dim bytChar
                        intLength = 0
                        For i = 1 to Len(strWord)
                                strChar = Mid(strWord, i, 1)
                                bytChar = Asc(Mid(strWord, i, 1))
                                If bytChar < 0 or bytChar > 255 Then
                                        intLength = intLength + 2
                                Else
                                        intLength = intLength + 1
                                End If
                                If intLength > intByteLength Then Exit For
                                FixString = FixString & strChar
                        Next
                        FixString = FixString & String(intPadDotAmount, ".")
                End If
        Else
                FixString = ""
        End If
End Function

你是在哪里要显示这样的内容的.
<%=left(trim(rs("detail")),50)%>这样的是可以显示的.

一楼的比较全面，不过它没有去掉HTML代码功能，，因为很多新闻内容都是以HMTL代码模式存到数据库的。。。
