I don’t know if that could help, but Ohm symbol is possible in Graphic mode
```
      ! Initialize Graphic mode
       ! Change Character Set to "Symbol"
       ! Display Ohm sybol ("W" letter)
       !
       GCLEAR
       GFONT IS "Symbol"
       MOVE 10,50
       LABEL "W"
       !
       END
```

You can also write the functions you need yourself using NIDAQ32.dll directly, but this will probably take you a lot of time…
The command descriptions are here : NI DAQ dll commands

Hi Tony,
First thing to do is to modify the NI Driver call in your software, normally in the “AUTOST” program
LOAD BIN “GPIBNI;DEV GPIB0 ISC 7”
“GPIB0” and “ISC7” need to be compatible with what you have in your NIMAX parameters

Hi Paolo,
“htb8dde.csb” is a tool from the MS Office interface
The best way may be to ask them directly why you are encountering this unexpected error

Hi all,
Thanks for the link. I downloaded the last HTBasic version 21.1.015 and the results are indeed differents.
With this new HTB version the program don’t stop now before the end but from L64C64 cell, the reading in the EXCEL file are always empty (Return$=””)
Very mysterious …

Thanks PatB for your Tips.
The code display is beautiful now 🙂

Hi PatB,
my test results with HTBasic 2021 are not better. The program stops and closes without an error message. According to my displays this happens while it tries to read the values on line 64 but the column seems more random…
Well anyway, I’m going to use the alternative method recommended by Ralph which works whatever the HTBasic version.
I put here my code using EXCEL reading which is defective

Hi Ralph,
Thanks a lot for your alternative method. That’s a really good idea that I hadn’t thought of 🙂
Please find below my new code applied …
I note your proposal for the HTBasic 2021 test, I will send you an email very soon

PS:
I confirm it’s not easy to paste HTBasic code in the forum.
I’m very curious to know how PatB managed to keep his indentation in his message !

Hi PatB,
Thanks for help and test.
I made some modifications in my code according to yours (please find below my complete updated code)
Unfortunatly after a lot of tests on different computers, 2 different EXCEL version, 2 different HTBDDE.dll version, different EXCEL files (including one completely blank EXCEL file) I always have the same error.
My maximum number of read is 16379 (L64C62) …!!!
Please could re-test my last code on your computer and verify on your side ?
Thanks again
Regards,
ZeRider

Do you have made the configuration of the WIN-PRNT print driver in the HTBasic Device Setup ?
October 17, 2023 at 3:59 am in reply to: NI GPIB-USB-HS+ interface #9233

I found out why it didn’t work.
The “primary address” of the NI interface was not initialized to 7.
Fixed by changing configuration with NI-MAX

I confirme it’s possible to use NI interface (GPIBNI driver) with KEYSIGHT instruments
I used these configuration many time in the past but I will try to install KEYSIGHT VISA as Secondary and re-test …
I keep you inform

Hi Ralph,
I have HTBasic rev 21. Now there is an automatic search when you try to add a new device but nothing is found at the end of the procedure …
I tried to add manually the GPIBNI driver (gpib0) , but when I try the classic Idn? on my instrument (Keysight Analyzer) I have the error “Interface not present”
I can’t add manually the USBS driver because the Agilent I/O libraries aren’t installed
