clearing string indicator

[Rhayes]

Sorry for all these questions but I'm so new at this Labview and I kind of want to impress my boss! 😉

I have a string that gets sent to a file log as well as a string indicator, I would like to clear the string indicator with a clear log button, in my code graphic I have a case statement with a selector to the clear log button, on the true side I have an empty string that I will wire to the input side of the shift register but since I don't want anything to happen on the false side and since I have to wire up the false side because it is an output I don't know what to put in there so nothing will affect the string indicator, what should I place on the false side?

Hi Ron,

take a look at this diagram, If I got it right, it does what you're looking for.
Good luck,

If you just want to clear the indicator then just create a property node or a local variable and wire a constant to it.

I have a slightly different question: I have a multiline string going to display my test's progress.  I want to save this into a text file, but only once the test is done, as a one formatted string.  If I choose to clear the display every time the vi is called I obviously only end up with the last run of the VI.  I want to clear the multiline string when my main program start at the initializing stage of the state machine.  Anyone know how it's done, clearing the multiline string display?

A string indicator is the same whether you drag it to make it larger to display multiple lines or leave it with the default appearance. Clearing a string indicator is described above.

Well, I am under impression that if you start sending empty strings into a multiline string it will append them rather than overright the existing data.

[Dennis_Knutson]

Your impression is wrong. A string indicator will not append a new string to an old unless you have written some code to do that. In fact, there is really no such thing as a multiline string. There is just a string. Maybe you are confused with another type of control/indicator.

Yes, you are wright, I had written something to append to the string and forgot about it.  Thanks for your help.
