Choosing Upload Method

There are three ways to handle file uploading with Pure ASP Uploader. You can choose one based on your application requirements.

Simple Upload

Simple Upload is designed for the simplest usage scenario. It calls the SaveDirectory method of the control which actually performs the upload. It automatically parses the information POSTed by the browser, figures out how many files are being uploaded, and saves them in a specified local directory on the server under their original names. An attachment table is also created.

<% @ Language="VBScript" %>
<html>
<body>
<form id="form1" method="POST">
<%
Dim uploader
Set uploader=new AspUploader
uploader.Name="myuploader"
uploader.SaveDirectory="/myfolder"
uploader.Render()
%>
</form>
</body>
</html>

That's all that's needed. Really!

Standard ASP Upload

If your usage scenario is close to the simplest case, described above, but you need a little more control, you can use Standard ASP Upload. It allows the ASP developers to process the uploaded files using ASP code. The page posts back to itself to process the uploaded files.

<%@ Language="VBScript" %>
<html>
<head>
</head>
<body>
<form id="form1" method="POST">
<%
Dim uploader
Set uploader=new AspUploader
uploader.Name="myuploader"
uploader.Render()
%>
</form>
<%
If Request.Form("myuploader")&""<>"" Then
Dim mvcfile
Set mvcfile=uploader.GetUploadedFile(Request.Form("myuploader"))
Response.Write("<div style='font-family:Fixedsys'>")
Response.Write("Uploaded File")
Response.Write("<br/><br/>FileName: ")
Response.Write(mvcfile.FileName)
Response.Write("<br/>FileSize: ")
Response.Write(mvcfile.FileSize)
' Response.Write("<br/>FilePath: ")
' Response.Write(mvcfile.FilePath)
Response.Write("</div>")
End If
%>
</body>
</html>

Custom file upload handler

If you need further control over the parsing of the file uploading request, you can write a custom file upload handler. In handler page (UploadUrl) developers can rename the uploaded files, process other logics programmatically.

<%@ Language="VBScript" %>
<html>
<head>
</head>
<body>
<%
Dim uploader
Set uploader=new AspUploader
uploader.UploadUrl="myhandler.asp"
uploader.Render()
%>
</body>
</html>

The following code shows you how to rename the uploaded files, process other logics programmatically in handler page (UploadUrl).

<%@ Language="VBScript" %>
<%
Dim uploader, mvcfile
Set uploader=new AspUploader
Set mvcfile=uploader.GetValidatingFile()
If mvcfile.FileName = "some.bmp" then
uploader.WriteValidationError("My custom error : Invalid file name. ")
Response.End
End if
targetfilepath= "savefiles/myprefix_" & mvcfile.FileName
dim fs
Set fs=Server.CreateObject("Scripting.FileSystemObject")
if fs.FileExists(server.mappath(targetfilepath)) then
fs.DeleteFile(server.mappath(targetfilepath))
end if
set fs=nothing
mvcfile.MoveTo( server.mappath(targetfilepath))
uploader.WriteValidationOK()
%>
