2. Using the ADODB.stream object, download the various files on the server in IE browser.
Response.Buffer = True
Dim strFilePath, Strfilesize, strFileName
Const adTypeBinary = 1
strFilePath = "File path"
Strfilesize = ... File size, optional
strFileName = "FileName"
' Need to install MDAC 2.6 or MDAC2.7 on your server
Set objstream = Server.CreateObject ("ADODB. Stream ")
objStream.Type = adTypeBinary
Strfiletype = LCase (Right (strFileName, 4)) ' File name extension
' Judge content-types by file name extension
Select Case Strfiletype
Case ". asf"
ContentType = "VIDEO/X-MS-ASF"
Case ". avi"
ContentType = "Video/avi"
Case ". Doc"
ContentType = "Application/msword"
Case ". zip"
ContentType = "Application/zip"
Case ". xls"
ContentType = "Application/vnd.ms-excel"
Case ". gif"
ContentType = "Image/gif"
Case ". jpg", "JPEG"
ContentType = "Image/jpeg"
Case ". wav"
ContentType = "Audio/wav"
Case ". mp3"
ContentType = "Audio/mpeg3"
Case ". mpg", "MPEG"
ContentType = "Video/mpeg"
Case ". rtf"
ContentType = "Application/rtf"
Case ". htm", "html"
ContentType = "Text/html"
Case ". asp"
ContentType = "Text/asp"
' Handle all other Files
ContentType = "Application/octet-stream"
Response.AddHeader "Content-disposition", "attachment"; Filename= strFileName
Response.AddHeader "Content-length", strfilesize
Response.Charset = "UTF-8" client browser's character set UTF-8
Response.ContentType = ContentType
Set objstream = Nothing
3. Improve the response rate of ASP pages
On the first line of your ASP page, add:
<% EnableSessionState = False%>
This closes the session object and increases your server response rate, and the more common problem is that an HTML page contains two frames
Page (at least one is an ASP page, and use session), which will make it necessary to wait for a frame page (of course this box
When the session is used in the rack page, the other frames page will not be displayed until the load is finished.
If you use proxy access, by default, many proxy servers do not dynamically cache ASP page content, adding the following code:
Response.CacheControl = "Public"
This line of code caches ASP pages on the proxy server, speeding up the response rate of the client requesting dynamic pages, and some infrequently changing ASP pages are made directly from the proxy server.
4. To know that the browser (ie, for example) will not parse return and newline characters, if you use the Response.Write method to write a line containing a carriage return and newline characters of the string to the dynamic page, the results can be imagined, you need to do is:
Response.Write (Replace (Body, vbCrLf, "<br>"))
Use <br> to replace carriage return and line wrapping. Note: If the carriage return and newline characters appear in the Input/textarea and other controls in the form, you do not have to do so.
5. Write IIS log with ASP code
Response.appendtolog "database is being accessed"
After executing this code, the following string may appear in your IIS log:
127.0.0.1,--01/01/00, 12:00:34, W3svc1,webserver,
127.0.0.1, 161342, 485, 228, 0, GET,/somefile.asp, database is being accessed
Note: Because the contents of the log file are separated by commas, the log content written should avoid using commas.
6. How to access the MDB database file on a remote computer
If you use an ODBC connection (DSN method or otherwise) to an MDB file on a remote computer, this will produce an error:
Microsoft OLE DB Provider for ODBC Drivers error ' 80004005 '
The general meaning is that the file may be accessed by another user or without sufficient privileges.
Here are two ways to avoid this error:
Way A. Using the DAO engine to access
Dim File, Conn, RS
Const ReadOnly = False
File = "\\server\share\file.mdb"
Set Conn = CreateObject ("DAO. dbengine.35 "). Workspaces (0). OpenDatabase (file,,readonly)
Set RS = Conn.openrecordset (SQL)
Mode B. ADO + Jet OLE DB provider method
Dim Conn, RS
Set Conn = CreateObject ("ADODB. Connection ")
Conn.provider = "Microsoft.Jet.OLEDB.4.0"
Set RS = Conn.execute (SQL)
Make sure that you have sufficient access rights to access the MDB file on the remote computer when you run the ASP page, before you can access the MDB file
Log on to the remote computer and add the following code
Set UM = CreateObject ("Usermanager.server")
Um. LogonUser "Account", "Password", "Domain"
