How do
I upload to a data directory?

How do I upload to a database?
You may upload three files to a database
by creating the following HTML form:
- dataupload.htm
<HTML>
<BODY BGCOLOR="#FFFFFF">
<FORM METHOD="POST" ENCTYPE="multipart/form-data"
ACTION="DataUpload.asp">
<INPUT TYPE=FILE NAME="FILE1"><BR>
<INPUT TYPE=FILE NAME="FILE2"><BR>
<INPUT TYPE=FILE NAME="FILE3"><BR>
<INPUT TYPE=TEXT NAME="DESCRIPTION"><BR>
<SELECT NAME="CATEGORY" MULTIPLE>
<OPTION>Image
<OPTION>Text
<OPTION>Source Code
<OPTION>Archive
</SELECT><BR>
<INPUT TYPE=SUBMIT VALUE="Upload!">
</FORM>
</BODY>
</HTML>
- dataupload.asp
Uploading files to a to a database
requires a few more lines of code than that of a data directory as follows:
<% Set Upload = Server.CreateObject
("Persits.Upload.1")
- ' Upload files
Upload.OverwriteFiles =
False ' Generate unique names
Upload.SetMaxSize 1048576 ' Truncate files above 1MB
Upload.SaveVirtual "/data" ' Save to data directory
' Process all files received
For
Each File in Upload.Files
File.ToDatabase ' Save in the database as blob
"DSN=userid.dsn_name;UID=user_id;PWD=account_Password;",_
"insert into UploadTable (id, FilePath, image)values (12, '" &
File.Path & "',?)"
Next
' Display description field
Response.Write Upload.Form
("Description") & "<BR>"
' Display all
selected categories
For Each Item in Upload.Form
If Item.Name = "Category" Then
Response.Write Item.Value & "<BR>"
End If
Next
%>
Note: The "_" at the end
of a line is the end of that line and no more code should follow on that
line as it is a signal to ASP that this string of code follows on the next line.

How do I upload an image from my
database to a web page?
To include an uploaded image from your
database in a web page you can use a regular <IMG> tag in your HTML page
with the SRC attribute pointing to the asp script. Please see the following
examples:
- getimage.htm
<HTML>
<BODY<br> <IMGSRC="getimage.asp?id=12">
</BODY>
</HTML>
- getimage.asp
<% Set Upload =
Server.CreateObject ("Persits.Upload.1")
Set db = Server.CreateObject("ADODB.Connection")
db.Open "userid.dsn"
Set rs =db.Execute("SELECT image FROM uploadTable where id = "
& Request("id" )
Response.ContentType = "image/gif" (or
"image/jpeg")
Response.BinaryWrite rs("image")
%>

Which methods and
properties are disabled for ASP Upload?
The UploadManager.Save method is
disabled.
Note: When the
UploadManager.Save method is disabled, ASP Upload users will have to use the
SaveVirtual method. That method accepts a virtual, rather than physical,
directory as an argument. This way, users will be confined to their own virtual
directory and subdirectories.
The UploadManager.FileCopy and
UploadedFile.Copy methods are disabled.
Note: When the
UploadManager.FileCopy and the UploadedFile.Copy methods are disabled, the
users will be forced to use UploadedFile.CopyVirtual.
In addition to the above-mentioned
methods, the following methods are also disabled:
UploadManager.LogonUser
UploadManager.RevertToSelf
UploadedFile.AllowAccess
UploadedFile.DenyAccess
UploadedFile.RevokeDenial
UploadedFile.RevokeAllowance
UploadedFile.SetOwner
UploadManager.RegisterServer
UploadManager.RemoveDirectory
UploadManager.DeleteFile
UploadManager.SendBinary
