Al Ain asp No component upload Class (upload component) documentation

First, Introduction
Since the contact ASP began to contact upload, saw some upload class, but always feel that the package is not simple enough, so I try to
Write an upload class that allows you to upload in the simplest possible way with the least amount of code.
In the school period began to write, a little bit of perfection, optimization, to the current version, the current version can adapt to various upload methods. On
The main functions of the pass class are as follows:
1, free to set the maximum upload size, single file maximum upload size
2. Freely set the type of files allowed to upload
3, can set the text encoding, to adapt to the various upload environment
4, built-in progress bar, a user can choose to open and close
5, a variety of error status processing
6, a variety of file saving method: The original file name, random file name, user-defined file name
7. Freely choose whether to overwrite existing files
8, complete save form data, support the same name form, does not support the same name file field
Attention:
1, pay special attention to the form must be added enctype= "Multipart/form-data" attribute, method property value must be post, no
The upload will go wrong
2, Request.Form () method to obtain data invalidation, please use upload.forms ()
3, before uploading, please confirm that the folder to save the file has read and write permissions, if not writable will appear "file cannot write" error, workaround

Ii. Method of Invocation
1, the method of calling no component class:
Dim Upload
Set Upload = new Anupload
2, the method of calling the component:
Dim Upload
Set Upload = server. CreateObject ("Jo.upload")
Note: The settings for the upload property must precede the call to Upload.getdata ().
Simple Invocation Example:
Dim Upload
Set Upload=new anupload ' Set Upload = Server. CreateObject ("Anasp.anupload")
upload.singlesize=1024*1024*1024 ' Sets the maximum upload limit for a single file, in bytes; default is no Limit
upload.maxsize=1024*1024*1024 ' Set maximum upload limit, in bytes; default is unlimited
Upload.exe= "Bmp|rar|pdf|jpg|gif" ' Set the legal extension to | split
Upload.charset= "gb2312" to set text encoding, default to GB2312
Upload.openprocesser=false ' Disable progress bar function, if enabled, need to cooperate with client program
Upload.getdata () ' Get and save data, you must call this method
Iii. Description of the class
Upload involves 2 classes of-anupload (key upload Class) and UploadFile (file class, save file related information), respectively
