Opening VI reference from a RIo

Dhasa — Thu, 09 Apr 2009 23:26:59 GMT

Hi Everyone,

When I try to open a VI referece using "Open VI reference" from a Rio 9074, I keep getting error 1026 (VI reference is invalid). Here is what I have been trying : If I wire a VI path of "C:\example.vi", I FTP into the the Rio and place the "example.vi" file in the Rio memory. But as I said, deploying it and running it from the Rio always returns error 1026.

Your help is appreciated!

What exactly are you trying to achieve over here? If possible, be sure to post a snapshot of your Project Explorer so we can understand your directory structure.

Hi Adnan,

I am trying to open the front panel of a VI using my main program that is running on the Rio. To do this, I am using the open VI reference and invoke method functions in my main program. I have placed the VI that needs to opened in the Rio's memory.

That's what I am trying to achieve. Please let me know if you have any ideas as to why I keep getting an error.

You have to open an application reference to the rio (use the TCP/IP address
of the device). Once you have an application reference, wire that reference
to the open VI reference, and use the name of the vi to open a reference to
that specific VI.
