taylermail · 发表于 2004-12-22 15:24:00

下面这个网页可以正常显示dwf文件(利用Autodesk Express Viewer工具)

cad_view.asp

<%
if Request.QueryString ("pipe_num")<>"" then
pipe_num=Request.QueryString ("pipe_num")
else
pipe_num=543

end if
%>
<html>

<body>

<tr height="90%">
<td colspan="10" align="center">
<object id = "viewer"
classid="clsid:A662DA7E-CCB7-4743-B71A-D817F6D575DF"
codebase="http://www.autodesk.com/global/expressviewer/installer/ExpressViewerSetup.cab" width="100%" height="100%" >
<param name = "Src" value="images/<%=pipe_num%>.dwf">
</td>
</tr>
<br>

</body>

</html> 前面是在images文件夹里有几个dwf文件,可以显示,如果我的dwf文件以Binary 存在数据苦里,该如何显示啊??????
<%
dim s,dwf,num
if Request.QueryString ( "pipe_num ") < > " " then
num=Request.QueryString ( "pipe_num ")
else
num=543

end if
set connGraph=server.CreateObject( "ADODB.connection ")
conngraph.ConnectionString =session( "connection_string ")
conngraph.Open
set rec=server.createobject( "ADODB.recordset ")
strsql= "select * from pipe_map where pipe_num=' "&num& "' "
rec.open strsql,connGraph,1,1

Response.ContentType = "image/dwf" '什么意思?小弟不懂?
Response.BinaryWrite rec("pipe_map").GetChunk(750000) set rec=nothing
set connGraph=nothing
% >
<html >

<body >
<br >
<tr height= "90% " >
<td colspan= "10 " align= "center " >
<object id = "viewer "
classid= "clsid:A662DA7E-CCB7-4743-B71A-D817F6D575DF "
