trackbar message codes.

VS2015 compiler throws the following errors.
Severity Code Description Project File Line
Error C2065 'TBM_SETPAGESIZE': undeclared identif
Error C2065 'TBM_SETPOS': undeclared identifier T

The same code compiles successfully under VS2010.
In other words VS2010 recognizes these symbols, and VS2015 does not.

Why is that? Perhaps Microsoft considers such product-to-product inconsistencies to be a "product improvement". I do not.


In what header file might these symbols be defined?

True to form, none of the so-called "help" resources from Microsoft provides any useful information on this subject.

Can any of my fellow victims of Microsoft incompetence help me with this?

I thank you in advance for any assistance you can offer.

Note the header file indicated. Trivial to find. I think you're rather a victim of your own.

As off-the-wall as this sounds:

Did you include the common control header? <CommCtrl.h>

My copy of VS2015 didn't recognize the track bar messages until I included the header.
