[Gambas-user] Using a socket to download an image. Please Help ^_^

[Robert Moss]

The ImgData stops writing when it comes to a byte with value &H00 (I
believe) although I'm pretty sure it doesn't matter how I write the stream,
once it's read as a String, it becomes terminated by any NULL char. So my
question is this: How do I read the data from the Socket in binary, write it
to a stream file in binary, but STILL I MUST be able to split the data based
on the 2 CRLF's
