.NET Forum / ASP.NET / General / February 2008ActiveX File Upload
Hello all, I am thinking about writing my own ActiveX File upload control in order to try and speed up files being uploaded / FTP'd to my webserver. My first question is, will this make a difference in the speed of the files being uploaded? Second, does anyone have any pointers or suggestions for me on things I should watch out for or examples? > I am thinking about writing my own ActiveX File upload control things I > should watch out for ActiveX is restricted to Microsoft Internet Explorer - no other browsers supports it, nor are they ever likely to... While IE represents the largest share of the browser market (http://www.thecounter.com/stats/2008/January/browser.php), you should really think carefully before using ActiveX on a public website...  SignatureMark Rae ASP.NET MVP http://www.markrae.net http/ftp upload use a standard tcp/ip stream to upload a file. you cannot make this go faster with your own code. you have two options: 1) add compression before upload (zip it first), this won't work if already done. 2) write a private protocol not using streams, but switch to UDP. UPD is not a reliable protocol, so you need to handle sequencing and rebroadcast of lost packets. UPD is faster than TCP because there is no ack between packets. you usually send multiple packets then a ack pack. note: tcp/ip now uses sliding windows (more packets before ack), so you will need to be a really good coder to beat it, but you can. -- bruce (sqlwork.com) > Hello all, I am thinking about writing my own ActiveX File upload control > in order to try and speed up files being uploaded / FTP'd to my webserver. > My first question is, will this make a difference in the speed of the files > being uploaded?

Thanks Bruce, my idea of writing an activex control was so I could add compression to the files or resize images being uploaded. I am pretty sure this has to be done using sometype of active x control, am I correct? > http/ftp upload use a standard tcp/ip stream to upload a file. you cannot > make this go faster with your own code. you have two options: [quoted text clipped - 26 lines] >> me >> on things I should watch out for or examples? yes. the active/x control will also need to be signed. or you could write the tool in silverlight. -- bruce (sqlwork.com) > Thanks Bruce, my idea of writing an activex control was so I could add > compression to the files or resize images being uploaded.
