[Shivam Shrivastava]

Hi Marcus,

Thank you for the reply.  Sorry I should have given you the exact example. I'm attaching the screenshot with my comments, could please refer the below image.

If you need any further clarification, please let me know. 

Looking forward to hearing from you.

Thanks & Regards.

Dear Shivam,

the mailing list archive shows no record of you ever contacting this
list under the subject "Regarding File source Block Funtionality"[1] or
from someone named Shivam at all[2].
This, together with the fact that we're basically participating on this
list in mostly unpaid time might explain why you've never heard from
us.

First of all: it makes no sense calling an output file *.txt. It's not
text, see our FAQ [3].

It's not clear what you'd want to do here: The slider is not a display
element. Your requirement doesn't make much sense. What's the *purpose*
of all this?

Best regards,
Marcus

As per my requirement, I need to implement a functionality which controls the content of file source through the sliding bar or progress bar i.e. if IQ file is read only 50% then slider should move to 50%. I have tried different approach and searched on the internet but couldn't find any workaround  through which I can manipulate the File Source Block.  Just a quick update I'm doing my project in python and would like to implement this feature in the same source code.

In simple term, is there any way to know how much input file has been read in File Source Block. Any lead would be really helpful. Let me know if you need further clarification.
