How can I open a vi and show the block diagram?

[m3rl3n]

Well, once again I get caught for skimming.  I did find the open / close VI in examples as specified above, and it performs the job as needed.  I tried to open the block diagram of the VI to see how it was opening and closing the VI, but is is password protected ;(

either way... there is a viable reason for the need.

Well, you're following up on a thread that's over four years old, but there is a way. Unfortunately, it uses a private property, which is not documented. See here for an example.

CC used the Open BD method in the llb he posted in this thread.

If you're using 8.6, you can now access everything needed for this without going through back doors. Have a look at the LabVIEW APIs group here, but be sure to read the various warnings and details.
