Public Methods

Method	Description
MultipartForm ( string url ) : System	Initialize our class for use to send data files.
getFileheader ( string aFilename ) : string	Returns the proper content information for the file we are sending. Hits Patel reported a bug when used with ActiveFile. Added semicolon after sendfile to resolve that issue. Tested for compatibility with IIS 5.0 and Java.
getFiletrailer ( ) : string	Creates the proper ending boundary for the multipart upload.
getFormfields ( ) : string	Builds the proper format of the multipart data that contains the form fields and their respective values.
getResponse ( ) : void	Here we actually make the request to the web server and retrieve it's response into a text buffer.
getStream ( ) : Stream	Determines if we have a file stream set, and returns either the HttpWebRequest stream of the file.
sendFile ( string aFilename, CookieContainer cookies ) : void	Transmits a file to the web server stated in the URL property. You may call this several times and it will use the values previously set for fields and URL.
sendFile ( string aFilename, Stream readIn, CookieContainer cookies ) : void
sendFile ( string aFilename, byte data, CookieContainer cookies ) : void
setField ( string key, string str ) : void	Allows you to add some additional field data to be sent along with the transfer. This is usually used for things like userid and password to validate the transfer.
setFilename ( string path ) : void	Used to signal we want the output to go to a text file verses being transfered to a URL.
writeString ( System io, string str ) : void	Mainly used to turn the string into a byte buffer and then write it to our IO stream.
