Scan string

[*E*]

I'm trying to scan one long string and the length may vary. I'm trying to display each character. for example.

Example.

,,,,,,,,,,,,,,,,,*1E        if they are 2  commas back to back then stop the scan.

04,05,08,10,11,,*1E   In this case i would like to first scan the string  from left to right and display the numbers before the comma as long as there isn't 2 commas back to back

04,05,08,,,,,,,,,*E    In this case I would like to scan the string from left to right and display the numbers before the comma 04 and 05 and 08 and stop there are 2 commas back to back.

Depending upon what you are going to be doing with the data next, use the spreadsheet string to array function to turn the string into an array of strings and then search the resulting array for the first element containing a null string. Then pass everything before the null element to the function for turning a numeric string into a number and (hey, presto) you have an array of numbers.

Or,  just use split string.vi from deep in the bowels of vi.llb

Exit a auto indexed loop on null string and rip off the last element if it was null

It is a string that constantly updates.i was able to use the spreadsheet string to array function, but not sure how to search the resulting string for the first element containing a null string sorry please explain.

can you post your split string.vi in labview 2009 please because i can't find it online?

Its is ...\LabVIEW\vi.llb\AdvancedString\Split String.vi.  it is not on the palattes because its an undocumented function.

Need a better post there E.  Thats like asking " Hey, I need directions to the nearest bathroom".  Not much we can help with if we don't know where you are.

Show us what you have (Post the vi you are working on)

Post what it does wrong (what input (s) give you "Bad outputs)

post what you want it to output
