Read data of embedded web page

[Wilmer]

HI, I have a medical instrument which can be monitored remotely using the ethernet port, this instrument has an embedded web page, using the Internet Explorer  I can read a series of data displayed on the page but I just need to capture a single datum of this page using Labview, someone give me any suggestions on how to read this data.

Thank you..

I did something similar a long time ago. The image below shows a method using data socket to read the source code of a webpage. The returned string can then be manipulated to get the desired data value.

Not sure if this will help you but the code show above also required a username/password (i removed them for security purposes!!).

This url worked for me:

For some reason the editor kept putting a smiley in the middle of the URL, so see the attached image!!

Hi SSK, I am sorry for my insistence but I do not understand, you could put a picture of this, do not really understand that you try and tell me with http://.........  change the names of your url...

I was trying to say that it is an image of text (if that makes sense!), here is the image again (immediately below):

Hi Wilmer,

did you try to monitor the communication between your device and your pc if you connect per browser? If you do it, and it's not a SSL connection, then you should be able to see what you have to send from labview.

It sounds like a normal HTTP Authentication, so you can send your USER and PASSWORD base64 coded.
