Find position

[kourte]

Hello,

I have several huge files. The problem is when I would like work with them, it's very long.

That's why, I try to search the position in the file. It's a same principe when you search one word in a dictionnary. If you search the word "painter" you known it's after the middle of the dictionnary.

Therefore you go directly in this section.

I would like apply the same idea but instead of a word I'm looking for dates. But it doesn't work.

You can found in attachment my vi.

Thank in advance.

I believe your looking is called a binary search. for the principle just type that into google

i have found an example on this site but have not looked into it to see how applicable it is too you tho

Hi kourte,

maybe the problem is your mixing of the state enum with some file position numbers in case "1" of your case structures?

I suggest making that enum a typedef!

 Oops, I have change one thing before send the file and I don't see it change my enum. But the problem comes not from here.

Hi kourte,

"Oops, I have change one thing before send the file and I don't see it change my enum. But the problem comes not from here."

I do believe that's part of the problem when you screw up your state machine like this!

Hello GerdW,

yes it's a part of my problem, thanks. I have correct this error but it's around in circles... I get no result

[GerdW]

Hi kourte,

you still screw up your statemachines.

In case 1 you don't provide a new state but instead wire the file position as new state. I believe this will not work...

Hi GerdW,

I have considered your comments but I have no information that appears.

Do you see why?

Finaly, I successful to display informations on my array but it don't display the good information...
