"At the return the byte count is 129154 bytes. After the call br is
127376 bytes."
I interpret this as fnBuildImageFile() returns a stream of length 129154
and the BinaryReader actually contains a stream of length 127376. Sounds
to me an issue with the defualt encoding of UTF8 on the BinaryReader? You
may try the constructor BinaryReader(m_msImage, Encoding.ASCII) for
creating the BinaryReader.
When writing to a file works, what encoding is being used?

having a little trouble. The problem may not be in the BinaryWrite. Here
is a couple of snippits. First is the Function that builds the byte().
Then the call of the object. At the return the byte count is 129154
bytes. After the call br is 127376 bytes. I know that the
fnBuildImageByteArray works because I have another call that writes it to
a file and the file is fine. This is a remoted call. I don't think that
should cause any problems. It uses tcp and binary formater. When the file
is built it is on the remoted server. Thanks for any help.
