Hi Michael,
When I mean't the ".output" I was meaning when I am using the SQLite
command line tool, I type in ".output result.txt" and then type "select
raw_stream_in from queue;" to stream that result to file.
The result file only contains character up until the first NUL.
Also, I know it is an image file (binary) I am just in the habit on
having .txt extensions when doing testing as all I care about is the raw
data....in fact I should just leave off the extension entirely.
I have submitted my full code in my previous message, thanks....please
let me know if you see anything?
I ran your test below, on my Linux machine and it still has the same
issue, meaning after the INSERT into SQLite I do a ".output result.txt"
and it still only shows "AB" in your example....
Here is the result of running od -xa result.txt
0000000 4241 000a
A B nl
0000003
I must be doing something fundamentally wrong.....;-(
Thanks for the help so far, I really appreciate it.....
