Your mistake was ever letting visual studio even know about that batch
file.  Batch files properly belong to the operating system and with the
operating system and nowhere else.

Oh yes, and one other issue that am not too sure where/why it arose was
that 
the batch file I had created as a text file, and then renamed within
VS.Net 
2008 kept on giving me an execution error along the lines of:
--n echo is not recognized as an operable....

error message, but I then recreated it using notepad, retyped commands,
and 
pasted file into VS.Net solution explorer and problem went away, so I
assume 
it was something like either just a \n or \r character at the beginning
of 
the first line or something that the command line application (cmd.exe)
was 
picking up, and complaining about, and the only other time have really
seen 
something similar to this was when I created an HTML file in VS.Net, but

then renamed it to .php and tried uploading it to a linux box, since if
you 
plan to use <?php session_start... it really needs to be the very first 
thing in a .php file, but anyway...

Stay well
