If the formatting is otherwise clean (tabs exclusively as separators,
etc.) it should not be too difficult to write a little code that
converts your string into a 2D array of strings that can be used to
feed the table indicator.

Hello everyone. I have added a microsoft progress bar (ActiveX

but the problem is that when i try to launch the first VI, it's the

ONE progress bar available
Perfect,it works

To have a subVI open its front panel when it executes and close its

You can do this with multiple while loops running in parallel. Acquire

loop to analyze the picture data when something is in the queue. When
the queue is empty, this second loop will do nothing.

Hi,
JoeLabVIEW's suggestion is a good one. If you are new to LabVIEW,

Enjoy your coding.

Replace your number to decimal string with number to fractional
string and then you can specify the digits of precision you want.
I don't understand why you're using the number to decimal instead of
number to fractional. The purpose of number to decimal is to create an
integer string from any type of input. The purpose of number to
fractional is to create a floating point string.
Thank you Joe but I was already using the microsoft progress bar in
