who can tell me my program is right or not?

here is my program:

[anchovie]

Whether it's right or not depends on what it is you want it to do!

But after having a quick look, these things strike me as odd:

1) The cluster control on the front panel of your main VI gets unbundled, but the data doesn't go anywhere.

2) The sub-VI outputs a boolean, but nothing is done with this output in the main program.

I would echo Anchovie's statement that since we don't know what you are trying to do it is hard to say right or wrong. There just seems to be a large amount of code that has no purpose.

I would also add that there is no error handling in the VIs so if you are getting errors that may explain your issue, you aren't seeing them. I would add error handling and it may tell you the issue.

I mean that the Visa resource name control used by me is right or not?
