Transformation ASP No component upload

Upload | no components

All along, due to the limitations of FileSystemObject, so the biggest problem is the ASP file upload, most of the solution is to install Third-party upload components. There are many problems with third-party components, some components to register, and some components to add his copyright information to the form. There is also the compatibility of components. On the internet also circulated a lot of no component upload code, but can only upload text files, or only to upload files to the database. The author of this period of time in the study of ASP, found that no third-party components can upload any type of file. Wrote this class, to give everyone a convenient, the whole class placed in a file: Upload_5xsoft.inc in the Example directory there is a complete multiple file Upload sample program, you can use directly.

Because of "transformation no component Upload program" problems, many netizens have sent their own modified version, each has characteristics. Here, the author uses the user beam without fear to give a modified version, and then made some changes to solve the original found all the problems (specifically see the description). Upload speed has also been greatly improved.
