Saving an 2D array to a text file

[bluefocs]

Hi,

I have written a program in labview which does some particle analysis on an image. I have written a some C and compliled it as a dll to save a 2D array as a text file. (I used this this tutorial: http://decibel.ni.com/content/docs/DOC-1690).

This works fine until I transfer the program to another computer (it seems to want some other dll file associated with visual studio, which this other PC doesn't have).

I there an easier why to do this without using a dll file? I have attached the .vi file and the c code i was using. The .vi uses a black bmp image with white circles on it.

Thanks,

Jack

Hi Jack,

Use the LabVIEW File I/O functions to write the data to file. From what I see in your C code you write the data in text format. "Format into File" is very similar to the C fprintf function you're using.

Check the LabVIEW help/examples for more information.

Hope this helps,

Daniel

Ok thanks, I'll have a play. One of the reasons I did it in C in the first place was because I couldn't work out how to extract individual elements of the array and print them to the file individually (so I had some control over the formatting).

Cheers,

Jack

Well then you should learn some LabVIEW basics first

Good luck!

You could use the Index Array function :

What are the names of the 2nd and 3rd yollowish blocks? Can't find them at the moment.

Hi bluefocs,

these are "build array" and "array to spreadsheet string" - pretty basic

You really should learn the basics of LabView!
