VB.net StreamWriter Usage

Good Day
Experts:

I have a VB.net program here that I am trying to use a Streamwriter to create a log file.
The first time I grab the file and write out the line of data it works great...as designed.
Well, then I when the process runs again, I want to append to that file.  

Unfortunately, it is not appending it is clearing and putting the new line in it.  
I suspect it could be in my declaration --> Dim SW As New IO.StreamWriter(ResourcePathLog)

How do I do this so the StreamWriter knows to append to that file(ResourcePathLog)?

Please ask questions if my explanation is not good.

Thanks for the help,
