Error -1073807346 will get away when i run VI for second time

[buton]

This is the weird thing

i open the vi for the first time and run it and it will put out the error :

Error -1073807346 occurred at VISA Open in Prompt for com port.vi

Possible reason(s):

VISA:  (Hex 0xBFFF000E) The given session or object reference is invalid.

i run the vi for the second time and the error goes away.. and everything works...

i dont know whats wrong, have you had this problem also?

You know that almost threw me untill I re-read the vi name!

Dude, that's not how you write a "Prompt User" routine!  What is happening is that you read the VISA In Terminal run that value through the for loop (At warp speed burning a cpu core) while the user fiddles with the VISA in terminal.  BUT, nothing changes the value on the wire!  so you pass the "Old" value to the VISA Open.

I've been meaning to add Prompt(VISA).vi to my reuse for a while anyhow.  Thanks for the excuse.
