In the NI Library VI: Extract Numbers, the string control is automatically loaded each time the VI is opened with "Counting to five: one 2 three 4.0 five. Where is this string data coming from?

Even after deleting the string "Counting to five: one 2 three 4. five." from the string control and replacing it with another string the original string returns after the VI is saved then reopened. Where is this string data coming from? I've attached a copy of the library function. I've been able in my application to get around the problem by replacing the string control with a string constant. But I'm still curious as to what's going on.

Thanks,

Chuck,

String control has been set to default with the string you are seeing.  To change this, enter the new string, right click the control and select

Data Operations>>Make Current Value Default

Now save your vi.

Thanks, your suggestion works great. Just curious though, where is the default data stored when the VI is closed?

[Wayne.C]

Pretty sure it is stored in the vi as part of the string control.  You could also use an .INI file to store defaults and then init your front panel controls on startup.

Thanks, yes my plan is to use an .ini file for the final version of the software.
