default value of string

Dear all,

I have developed a program in Labview. In my program, there are some "string controls". I need to enter the value when file is opened(for example: IP address,port no.).Do you know how to set the default value of "string control"? I don't want to enter those value evey time. Based on the value may not constant, i don't want to use "string constant"
Thank you.

type value, right click on control and choose "make value default".

Another method is to write a value to a local of the control early in the vis execution, if you use a state machine an initialization state.

I prefer the second method since I use queued state machine designs for most of my UI vis.

when you're in edit mode, you can set the default value by right clicking on the control and selecting " data operations".

If you wanna set it in run mode you've to read/write from file. I think that this should be easier for you.
