Explanation

The IKHTTPGetFile function retrieves a file from the HTTP or the HTTPS server. (It includes connecting to and disconnecting from server.) This method can only be executed from the client computer. It does not operate on the server. The TransPercent parameter sets the percent of file tranferred before the User Function is called.

If the user function is set or if the Caption, Message, and Button parameters are blank then the Progress dialog box is not displayed. If the Progress dialog box is displayed, it indicates the percentage of the current process completed. For more information about the user functions please refer to the Definition of User Function in the Ik10File.dll, Ik10FileA.dll, Ik10File64.dll, Ik10File64A.dll section.

(*1)

When setting a proxy server, changing the port number, or using HTTPS, use the ServerName parameter to pass the necessary information. The information is passed in this parameter in the following order: HTTP(S) Server name or IPAddress;Proxy Server IPAddress;Port Number;HTTPS. (use a string with a semicolon to delimit multiple entries).

Note: If you do not specify the port number the default port number will be used. If you do not specify HTTPS then HTTP will be used.

A. Set a proxy server:
   ServerName = "www.newtone.co.jp;xxx.xxx.x.xxx"
B. Change the port number to 81:
   ServerName = "www.newtone.co.jp;;81"
C. Set a proxy server and change the port number to 81:
   ServerName = "www.newtone.co.jp;xxx.xxx.x.xxx;81"
D. Use HTTPS:
   ServerName = "www.newtone.co.jp;;;HTTPS"
E. Use HTTPS and change port number to 444:
   ServerName = "www.newtone.co.jp;;444;HTTPS"
