Hi Putnam,

Sorry to take so long to reply.

See attached code.

The forum wouldn't let me attach an xml file.

So here it is.  Simply remove the .txt extension at the end.

Thats pretty slick but it doesn't update the controls with the values stored in the config file.  Is there a way to do that with your example?

[Ray.R]

What do you mean?

The config file in this example is an xml file.  And it gets updated by whatever vaules you change in the control box on the left.

I modified the code to include indicators to show the original values from the xml file and the values  that will be written to the file.

See images below:

This is before running the program.  The change controls remembered the values from the last run.  You can set these to some initial value and save as default.

 

The top left shows the values that were in the config file.  The bottom left shows the new values that were set.

The bottom right shows the values that were written to the file.

 

Run the program again and the top left corner now shows the new values that were written to the xml file (the current contents of the file).  See, it does update the config file.

Or did you mean that you want the values of the control (bottom left) to be updated with the values from the xml file?

If so, then I will modify the example.

Yea.  When I run the program I want the controls to be updated to whatever is in the config file.  That way, if I only want one thing changed I don't need to remember what was there to begin with.

Oh.. Now I get it.  Okay.  I can modify the code; however, if you use a control as an indicator, then you will need to use property nodes.  I can modify the code and post it if you wish.  If so, it will have to be later today..  😉

Thats okay.  I just thought there might be a way of doing it without using the value property node or local variables.  Thanks for your help.
