B. ASP上傳圖片並保存到access資料庫某個表中的源碼，能詳細解釋一下源碼的意思
給你個例子：
1、access表有以下幾個欄位：
id 自動編號,
filename 文本,
type 文本,
what OLE對象,
size 數字
2、上傳頁面（upfile.htm):
文件上傳<br />
<form action="upload.asp" method="post" enctype="multipart/form-data">
文件 <input type="file" name="file1" /> <input type="submit" value="上傳" />
</form>
3、提交頁面(upload.asp):
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<!--#include file="UpLoad_Class.asp"-->
<%
dim upload
set upload = new AnUpLoad
upload.Exe = "*"
upload.MaxSize = 2 * 1024 * 1024 '2M
upload.charset = "utf-8"
upload.GetData()
if upload.ErrorID>0 then
response.Write upload.Description
else
dim file
for each frm in upload.forms("-1")
response.Write frm & "=" & upload.forms(frm) & "<br />"
next
set file = upload.files("file1")
if not(file is nothing) then
set conn = server.CreateObject("ADODB.connection")
conn.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ="&server.mappath("./")&"\db.mdb"
set rs = server.createobject("adodb.recordset")
rs.Open "pic", conn, 1, 3, 2
rs.addnew
rs.fields("filename") = file.LocalName
rs.fields("type") = file.ContentType
rs.fields("what") = file.GetBytes()
rs.fields("size") = file.Size
rs.update
Response.Redirect "listpic.asp"
end if
end if
set upload = nothing
%>
4、其中引用了UpLoad_Class.asp文件，是艾恩無組件上傳類，網上搜一下就能找到。
C. 如何解決asp源碼動態圖片橫向放置問題，原來是豎的
第一處：
while not rs.eof '填充數據到表格
'------------------------------------------------
fUrl = dode&".asp?SortID="&Int(Rs("SortID"))&"&ItemID="&Int(Rs("ItemID"))
Response.Write "<tr valign='top'>" & vbCrLf
這里改為
Response.Write "<tr valign='top'>" & vbCrLf
while not rs.eof '填充數據到表格
'------------------------------------------------
fUrl = dode&".asp?SortID="&Int(Rs("SortID"))&"&ItemID="&Int(Rs("ItemID"))
第二處：
Response.Write "</tr>" & vbCrLf
rs.movenext
wend
這里改為
rs.movenext
wend
Response.Write "</tr>" & vbCrLf
原代碼輸出是
<table>
<tr><td></td></tr>
<tr><td></td></tr>
<tr><td></td></tr>
</table>
你想達到的效果是
<table>
<tr><td></td>
<td></td>
<td></td></tr>
</table>
D. 急求ASP上傳照片並在另一頁上顯示出來的源碼，請不要粘貼其他地方的帖子了。
去看一看無懼上傳類 的使用方法 包含三個
Upfile.asp Upload.asp Upload.inc
多自己學習學習 以後再碰到自己也會了
E. asp圖片顯示源碼製作
你在資料庫中建一個叫pic_name的欄位
用來記錄圖片名稱
你可以在前台頁面中這樣寫
set rs=server....
sql="select * from...
...
...
<img sc="pic/<%=rs("pic_name")%>">
...
F. 圖片上傳的ASP源代碼
4個文件實現無組件上傳4個文件實現無組件上傳
嵌套式調用：
<iframe name="ad" frameborder=0 width=100% height=50 scrolling=no src=uploada.asp></iframe>
直接鏈接：uploada.asp
文件保存路徑：upload
上傳文件類型和大小自己設置
===========================================
第一個文件：inc/confing.asp（inc為文件夾名稱）
<%
Const EnableUploadFile="Yes" '是否開放文件上傳
Const MaxFileSize=200 '上傳文件大小限制
Const UpFileType="gif|jpg|bmp|png|swf|doc|txt|rar|zip" '允許的上傳文件類型

G. asp怎麼實現圖片文字圖片一起上傳源碼。求源碼
這個首先要查詢有圖片的新聞，讀取一條。然後取那條新聞以外的新聞。select top 1 * from tablename where img<>''
H. 隨機顯示一組圖片的ASP源碼
asp隨機顯示圖象<%dim p,ppic,dpic
ppic=12
randomize
p=Int((ppic*rnd)+1)
dpic="graphix/randompics/"&p&".gif"
%>
顯示 < img src="<%=dpic%>" >
