Re: [WIN32Lib] programmatically select tab item?
Derek,
Yes, destroy a tab item, then all contained controls should be destroyed
too, but more important is to make sure all contained controls for tabitems
to the right of the deleted one be "shifted" one to the left so they're
correctly associated with the tabitems that remain.
