NOTE: This method is called only if you
implemented IwodFTPDNotify interface in your application, and
wodFTPD.Notification
property has received reference to instance of your implementation.
Progress notification method is called during file
upload or download. You can track and calculate
client's speed using this property.
If user is uploading file, its size is not known before
upload is completed - thus Total
and Position arguments will always
contain same value - total number of bytes uploaded so
far.
Progress notification method will be called until file
size exceeds 4.2gb. After that size, Progress64
notification method will be called instead.
NOTE: it is possible that Position or Total
values become negative - it is because unsigned values are used, but
VB (and other environments) expect to see signed values. If this
happens, we suggest you call Progress64 notification from within Progress
notification, and apply code as shown in Progress64 help page.
