How to open multiple files in Labview?

[keiylh]

I want to open multiple files in labview by selecting multiple files,then read them? Can I do this in Labview 7.0?

You can use the vi example here to get multiple names:

Once you have the file names, you can use a for loop w/ a Read/Open file vi to open all the files.

Hi Wiebe,

Just downloaded this, modified it slightly, and changed it to LV 6.1 using the LV 7 Eval. Edition.

Excellent work.

Here's my version for anyone else whio wants it.

Cheers

Hi,

I have tested your code. Great work!. I need to open 612 files simultaneously, when I try to open this number of files they don't open.

Can you help me?

Thanks and Best regards.

What do you mean by "don't open" does it give an error of any sort or something like that. I ahve attached some code where I open 612 files write to them and close them. See what you can glean from it, and get back with me if you are still having problems.

Hi Rick,

Thanks for your response. I can't open your code because my version of LabVIEW is 7.1. Can you translate your code to 7.1 version?

If I use the library included in the post, I can open the dialog box and I can select multiple files, then I get an array that contains the paths of the files selected. Then I use a "for structure" to index the array and extract the files information.

So, If I tried to open less than 256 files, there is no problem, everything is OK, the array is full of paths information. But If I try to open my 612 files, the result array is empty, with no paths information inside the array.

Thanks you very much!. I hope you can understand my expressions, my english is not the best I would like.

Best Regards.
