Uploading files using XMLHTTP blocks

Writing ideas: The local file in the client through the base64 encoding after sending the destination.
During the test, the upload file was too large, which caused the timeout to be unsuccessful.
It was later improved. Send the code segment. Test 20M Success

Writing purpose: In the traditional solution, one at a time to select upload can. But it's a hassle when it comes to reading the file path in the database and uploading the files to a place.
If you get the path one to find with FTP of course is also OK, but every time I look for these files will be more time-consuming. This is done primarily to get files through the file path in the database. Upload files to one place at a time.
The main purpose is to exercise yourself.

Workaround: Initially try to use the analog keyboard input to forcibly assign the value to the file control to upload it in a traditional way. However, the old encountered a null value of the situation, so many documents have not been sent out. Look up some information, now is to take all the path through the database and then write to a JS. Then in the foreground with JS read these paths, through the XMLHTTP to send files.
Because IE does not like XMLHTTP. Always think he has malicious behavior. So always talk about warning. Therefore, you cannot use the Web path when you operate. You can only access it using a physical path.
The server then has a file to receive the encoding and decode it. So I call it "C/S." '

At present, a lot of code is still in perfect.
Brief introduction:

Aryfiles.push ("C:\\aaa.zip");
Aryfiles.push ("C:\\bbb.exe");
This is the file path and file. Available for multiple
This path can also be used by the file control on the client to access the

This is the destination, you can change to the address you want.

Ado_stream. LoadFromFile (Server.MapPath (".") & "/" & + Str_filename)
Server.MapPath (".") & "/" & + Str_filename Here is the read file.
Server.MapPath (".") & "/" & Path and storage path consistent

Ado_stream. SaveToFile Server.MapPath (".") & "/" & str_filename,2
Server.MapPath (".") & "/" & This is the path for storing files. Str_filename as FileName

Here the reading and storing are placed in the directory where the program is placed. You can keep it that way when you test it.

Place the first piece of code locally (eg:c:\upload.htm)

Put the second piece of code on the server, can be a local server, can be a public network server. Consistent with the destination above
(eg:http://www.xrss.cn/upload.asp or http://localhost/www/upload.asp)

Action: Locate the first paragraph where the code is saved. Execute (eg: Open C-Disk to perform upload.htm)
