Subject Please explain how this works

In this VI there are four String Indicators Data, From, To and Subject. If you look they are not connected with any wire and stile this VI will run with out any error not only that It will update the value according to what in the while loop in to CASE Structure.

This VI is the part of the POP Email application. I found it on NI web site.

Thank you for your great knowledge

You need to read up in the LabVIEW manual on local variables. That's what's being used to update the indicators.

By the way, the default value of the "Message Content" indicator is such that you won't get anything out since the Match Pattern is looking for  "Date:",  "From:", etc. In other words, you need a colon after the "Date", "From", etc. fields.

I miss those colons. Well that is a good way to use local variables when you have lots of wires.

Thank you

In this particular case, it seems silly to even use local variables. You might as well replace each local with its corresponding indicator terminal in the code. 😉

Yes that is right. I got this code from POPEmail Library. I did not understand that at first. Now I understand it.

Thank you
