Hitting a high-bouncing forehand, for example, actually takes a different stroke than hitting a waist-high or knee-high forehand. This is why most players have trouble with high-bouncing shots, whereas advanced players find them easy and love them because they can hit down on them aggressively. So, it's just a matter of practicing high-bouncing shots till you learn the special stroking motion needed.
I think Gasguet's tip is the most likely to work because it corrects the most common mistake. So I'd try that one first: try to contact the ball more out front. On forehands it might help to point at the approaching ball with your free arm.
Like others suggested, you can take the ball sooner (on the rise) or later (on the descent of the bounce). There are disadvantages to doing this, however. For one thing, taking the ball lower means you can't hit downward. Me? I'd take the ball lower rather than lose a match, but as a general solution to the problem, I'd look for something else.
If you are hitting the frame, you may be moving your head. Try to watch the ball better, so that you are still looking at the point of contact till AFTER you hit the ball. Doing that keeps your head still.
It sounds like you are hitting these shots from the baseline and expecting to hit winners. You can't hit winners from back that far, except on sharply angled shots that you hit from wide. In fact, you shouldn't be going for winners when you are more than about 14 feet from the net (less than 7 feet ahead of the service line). But if you're in the service line area, and you get a high-bouncing shot, you can hit down on it and follow your shot to the net.
