File Upload in WinSCP through vba

[ashokkumar1234]

I am trying to develop code for save the file in sftpcf (winscp) server but error in <code style="margin: 0px; padding: 1px 5px; border: 0px; font-style: inherit; font-variant: inherit; font-weight: inherit; font-stretch: inherit; font-size: 13px; line-height: inherit; font-family: Consolas, Menlo, Monaco, "Lucida Console", "Liberation Mono", "DejaVu Sans Mono", "Bitstream Vera Sans Mono", "Courier New", monospace, sans-serif; vertical-align: baseline; background-color: rgb(239, 240, 241); white-space: pre-wrap;">Session</code> and showing error as

user defined type not defined
​

I am not sure below code working or not and I copied the code from internet source.
any suggestion would be appreciated.
