Can anyone recommend books for TPW?

  Hi!  I'm trying to learn TPW 1.5, but I don't have any documentation
for it.  I'm mostly familiar with the procedural aspects of TP for DOS,
but OOP in Windows is escaping me.  Are there any articles on the net
written for this subject?  Or any good books that someone can recommend?  
Thanks in advance, Peace
