dim br as BinaryReader(stream)
dim buf(5000) as byte
br.Read(buf,0,5000)
closeit..
I have read a binary file into a buffer. This buffer contains many different
chars as well as a few null chars. I want to replace the (NULLS)chr(0)'s
with (SPACES)chr(32)'s. How can I do this. REPLACE does not seem to be an
option, If I converted it to a string I was afraid the string would stop at
the first NULL truncating the remaining chars. Any ideas on how to do
this...
Thanks
JT

All you have to do is iterate over the byte array and replace the occurances
of 0 with 32.  No need to convert it to a string.

But, you might want to keep track of exactly how many bytes you read from
the file and only iterate over that many in the array.

For i As Integer = 0 to buf.Length - 1
   If buf(i) = 0 Then
       buf(i) = 32
   End If
Next
