通过一下的两个函数可以实现图片，文字的同时提交处理。
Function BinaryToString(str)
strto = ""
for i=1 to lenb(str)
if AscB(MidB(str, i, 1)) > 127 then
strto = strto & chr(Ascb(MidB(str, i, 1))*256+Ascb(MidB(str, i+1, 1)))
i = i + 1
else
strto = strto & Chr(AscB(MidB(str, i, 1)))
end if
next
BinaryToString=strto
End Function

function gainformdata(n)
dim formsize,formdata,divider,datastart,dataend
redim mydata(n-1)
formsize = Request.TotalBytes
formdata = Request.BinaryRead(formsize)
for i=1 to n
bncrlf = chrB(13) & chrB(10)
divider = leftB(formdata,clng(instrB(formdata,bncrlf))-1)
datastart = instrB(formdata,bncrlf & bncrlf)+4
dataend = instrB(datastart+1,formdata,divider) - datastart-2
mydata(i-1) = midB(formdata,datastart,dataend)
formdata=rightB(formdata,clng(formsize-instrB(datastart+1,formdata,divider))+1)
formsize=lenB(formdata)
next
gainformdata=mydata
end function

弹出提示信息 , 确定 与 取消 怎么做的

6. 组合查询的优化，谢谢
sql = "select * from book where bname like ‘%" & txtbname.Text & "%‘ and bauthor like ‘%" & txtauthor.Text & "%‘ and bpublish like ‘%" & txtpublish.Text & "%‘ and bdescription like ‘%" & txtdescription.Text & "%‘ order by bookid desc"

组合查询，有是四个组合条件，这样写是不是效率比较低，我该怎么优化一下呢？
谢谢。

分析，在SQL中，用LIKE是比较费时间的，所以最好是少用。

同时　，四个TEXT框，输入条件是，一定会有没有输入的条件的时候，就会出现 LIKE "%"的情况，其实这种情况下就等于这个条件没有。

所以，把生成SQL语句的代码多写些，
Dim WhereStr as string
if txtbname.Text<>"" then
WhereStr="bname like ‘%" & txtbname.Text & "%‘"
ELSE IF ....
.....
ENDIF
这样是一个概率的问题，如果四个全输入的话，是一样的，但如果只输入一个的问，速度会比你的快些!

sql = "select * from book where "
If txtbname.Text <> "" Then
sql = sql & "bname like ‘%" & txtbname.Text & "%‘"
ElseIf txtauthor.Text <> "" Then
sql = sql & "bauthor like ‘%" & txtauthor.Text & "%‘"
ElseIf txtpublish.Text <> "" Then
sql = sql & "bpublish like ‘%" & txtpublish.Text & "%‘"
ElseIf txtdescription.Text <> "" Then
sql = sql & "bdescription like ‘%" & txtdescription.Text & "%‘ "
End If

8.如何禁止刷新

页面已经禁止刷新

12.
sql server 用:sql = "update reg set dealtime=getdate() where id= " & request.querystring("id")
因为 SQL SERVER里没有 now() 这个函数，而是用 getdate() 取代了
所以你的会报错.
ACCESS没有这个函数:)
只有date()和now()
