Question about how to call an .exe file from C#
alex boulet
I am really new to programming in general but I have this project
where I need to use C# and I can't figure out something.
The way it works, I need to run an executable file and take a text
file as input.
According to the documentation , from DOS, I would simply have to type
the following:
C:/program_name.exe C:/program_command.txt
This is pretty much the same way in Matlab by the way.
Does anyone know how to do this in C#?
I would really appreciate any help as I struggled the last few days
and it does not seem like something that should be very difficult to
figure out.
Thanks!
Alex.

Wrong newsgroup.

No. If you were asking about C, I'd say system();

The *ONLY* way in portable ANSI C to run another program
is system(). And the strings you pass it are system-dependent.
This newsgroup and the above comment apply to C. It may or may not
apply to C#, whatever that is, but my guess is that you don't have
a license to ask questions about this to anyone but Microsoft (nor
does anyone else).

What the heck is C#? This is a C group.

I think you're a little sharp. Your estimates (halved to bring them
closer to middle C) work out as
274.03282835213491333686830708301
and
280.33243360160927916070436011941
I make C# closer to
271.22255215597958772782727550626
which I derive from 256.0 * pow(2.0, 1.0/12.0)
Perhaps we should take this up in rec.music or whatever. :-)

In what system kind of system is C# a half-tone above 256 Hz? It looks
like you have been dealing with binary numbers for too long ;-) What I
would mind about Robert Stankowic's answer is that he assumes that
everyone is tuning his instrument to about A = 440 Hz, which a lot
people don't do.I for one often use a 415 Hz tuning fork (with C# being
261.433618 Hz) - but when you play with people with a keyboard instrument
you have to use what they have anyway ;-) And, of course, these formulas
only work when you use this horrible "well-tempered" (as it is nowadays
falsely called) system of tuning ...
Regards, Jens

The following is utterly OT, and maybe utterly wrong:
A above middle C is usually taken to be 440 Hz. To get from one note
to the next in the scale, one would multiply the frequency by the 12th
root of 2. C# is 4 notes past A, so the frequency would be about
440*pow(pow(2.0, 1.0/12.0), 4)
Which is about 554.365 Hz. Of course, this isn't the *only* C#. The
one you are looking for is half the frequency (one octave lower), at
about 277.183 Hz.

bzzt... middle A (A3) is 440 Hz.

A4 actually...

I searched for the terms (middle c frequency) on Google and the first
two documents returned caught my eye. The first contained this quote:
"A440 is the musical note A above middle C."
The second contained this quote:
"If the piano is properly tuned, middle C has a frequency of 256
cycles per second..."
Both of these back up my claim somewhat, but they are inconsistent
with each other. The second explains why Mr. Heathfield was using 256
(which a few of us apparently thought strange).
I suppose it's safe to say that there is more than one standard for
musical pitch.
