Hello,

maybe the answer is very easy, but I could not find it up to now ...

I have multiple direct IO commands in my HPVEE programm. To be flexible I
have added the control inputs with instrument name and instrument address to
the IO commands.
But now I do have two variables, that have to match.

I would like to bring this down to one variable. Means, I'm assuming, that
my GPIB address of an istrument is fixed. Now I would like to read somehow
the corresponding
name from the instrument manager which I can use for the direct IO command
as control input.
Therefore even after deleting the instrument, and finding an istrument
called "newInstrument" by a "search instruments" the programm would work
fine, as long the corresponding GPIB address of the instrument does not
change.

Is there any chance to find this kind of information, or is there even a
better way to get instrument type, name and GPIB address ?

thanks

Hello,
Does anyone know of a simple method for reading input from the keyboard
without using the text or message boxes supplied in VEE ?
I'm already using the SendKeys method of VBScript, and wondered whether
there was a similar method for getting keystrokes rather than sending them.
Thanks in anticipation.
Paul

Rich,

This can be frustrating at times. What I do most often is make sure each
function has a unique name, not just in the local library, but across all
libraries. I do this by prefixing the name of the function in every library
with a common descriptor, eg DMM_Initialize, DMM_Set_Volts, etc. Now,
whenever I CALL a function, I strip of the dot notation (eg
"import_name.DMM_Initialize" is CALLed as "DMM_Initialize") As long as your
functions have unique names, then there is no problem. However, you must
always remember to strip off the imported library name in every CALL that
you make.

You can also load all of the libraries into a common test program and test
them. Have the individual libraries open at the same time, and make changes
(and save them) in the libraries, re-load them into the test program, and
try the changes.

Hope it helps (and that I've understood your problem),

Reiner

I need some advice on working with libraries. I would like to have
instrument dependent subroutines in separate libraries, to be loaded during
runtime. If a specific instrument subroutine SUB1 needs to call another
instrument subroutine SUB2 in the same library INST1, I am running into
some gotchas during development. For the call to work in the main program,
the call needs to be to INST1.SUB2. But now, I can't play around in LIB1
directly, debugging, because if I call SUB1 in a test MAIN mdule, it calls
INST1.SUB2 which does not work. It needs to call SUB2 directly. So I
started making a SUB1local version also, for debugging. But this quickly
gets out of hand, having each routine twice.

Maybe I am missing some basic feature. How do others develop instrument
driver libraries?
