http://www.eprinting.cn/donetoutput2/outputsystem.aspx?uSername =pubuser In order to make a Dongdong uploaded by ASP, carefully study now popular upload code and components. But I didn't make me more satisfied. Program requirements: can upload large files, dozens of m to more than 100 M, can display progress. Let me first use ASP to achieve, and progress seems to have only windless components, but that speed and CPU consume, you can't stand it. . Even if you don't ask for progress bar, it is still too slow to use the Daoxiang hometown. Net. . I use lion.Web.uploadModule results to run locally, but it can't display progress bar on the server. Useful friends ask me to teach me, it is grateful. And an online program (passive code) I have seen is used by ASP to implement a big file upload. The speed can be displayed, and the progress bar can be displayed. I have tested that the 40M file did not appear. http://www.eprinting.cn/donetoutput2/outputsystem.aspx?username =pubuser is now sticked, I hope to have a good and technical friend to study, and can point out.
