Exchanging variables between C gauges and XML gauges

[Guest dougfreeman]

Hi, Sorry if this has been asked before but I have searched and not found the answer. Could anyone help me by giving example code of how to share variables between C and XML gauges. This is to allow complex calcs to be performed in C code and the results used in an XML gaugeMany thanks

Thanks for the reference to my "mini-tip" Patrick!I've just added a "Part 2" to the post explaining how to use the execute_calculator_code(); function as an alternative method. :)

Many thanks for the rapid replies guy's. I'm sure I'll crack this now.CheersDoug

Just read part 2 Bill, but not sure what you are trying to tell people when you say:

Note that the same structure may be made bi-directional, meaning that you can use XML to control the C variable, or use the C variable to control the XML variable.

as that function call will copies XML vars to the variable at the specified pointer, but not the reverse.If you are refering to Part I above, then you might want to make that clearer for the noobs. =)But who knows, maybe I have forgot something. =)Anyway, glad to point out your excellent tips that you took the time to make.

>If you are refering to Part I above, then you might want to>make that clearer for the noobs. =)Thanks. That'll teach me to try writing a coherent explanation that early in the morning when I'm still barely awake! ;)BTW, if you ever feel like posting a "tip", it'd be most welcome.While this forum is much busier, at least "over there" I have some control over the posts, and can easily collate tips into a more digestable form for quicker reference. ;)

Will do. Yes, it is a great place for that given that you can sticky them etc.Patrick
