LabVIEW
Setting default values for controls at runtime
You can't change the real default values of any front panel object after you build your applicaiton into an executable. Likewise, you can't change the default value of anything while in the developnet environment while your application is running, and for the same reason as the executable.
Changing the default value requires the code to be recompiled. Recompiling cannot be done while the applicaiton is running, or after it's built into an executable.
You can mimic this function by reading the controls and storing values in config files. Then use local variables to update the controls when needed.
You might want to take a look at the Openg toolkit. It has a set of config file vi's that can read an entire front p
anel, write it to a config file and read the file back so you can update the panel as needed.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.
The two VI's mentioned are not part of LabVIEW. They refer to an article that was in one of the LabVIEW Technicle Resource issues.
You could visit LTR's website and find out which issue the VI's were in and purchase that single issue to get the VI's. ($25 I think).
Or you could look into the Configuration File VI's that are part of the OpenG Toolkit I memtioned in my first answer. These are free to use.
Of course you cold also look into building your own using the Config file VI's that come with LabVIEW. On teh Functions palette, look in the 'File I/O>Configuration File VIs'. There's actually enough there to do it your self.
