*************测字符串长度**************
function checkstringlength(txt)
txt=trim(txt)
x = len(txt)
y = 0
for ii = 1 to x
if asc(mid(txt,ii,1)) < 0 or asc(mid(txt,ii,1)) >255 then 如果是汉字
y = y + 2
else
y = y + 1
end if
next
checkstringlength = y
end function
************* 截取字符串 **************
function interceptstring(txt,length)
txt=trim(txt)
x = len(txt)
y = 0
if x >= 1 then
for ii = 1 to x
if asc(mid(txt,ii,1)) < 0 or asc(mid(txt,ii,1)) >255 then 如果是汉字
y = y + 2
else
y = y + 1
end if
if y >= length then
txt = left(trim(txt),ii) 字符串限长
exit for
end if
next
interceptstring = txt
else
interceptstring = ""
end if
end function
