Hi
I am reading some data from an oscilloscope using the Internet Toolkit
I can download the image of the oscilloscope screen using the vi "URL Get HTTP Document"
with the URL "http://.../Image.png"
But "URL Get HTTP Document" returns an error with this other URL "http://...?setupsend=getsetup.set"
This URL is valid because I tested in a browser
The error is:
Code=54, Source=TCP Open Connection in URL Get HTTP Document.vi
I know the problematic URL has the structure of an URL produced by a HTML form
but I could not find other VI to perform the task
Is there any other VI available for this?
Any suggestions please
Regards
Rudy

Why are you using the Internet Toolkit instead of VISA? What scope? Did you look for a driver?

Hi Dennis
Thanks for your fast reply
Yes, I am also using VISA and I have an instrument driver for the oscilloscope
I need the Internet Toolkit only to download the screen image because there is not command to retrieve that information
For this the VI "URL Get HTTP Document" works fine
Just few minutes ago I found a command to retrieve the information I was trying to get from the URL "http://...?setupsend=getsetup.set"
Thus the problem was solved with VISA as you suggested
But now I am curious about the limitation of "URL Get HTTP Document" to manipulate those kind of URL
So I will keep the question open
How can I download a file from an URL like "http://....?var=value" ?
