Dear Hans,
Thank you for your answer.

Yes, it clears everything in the frame.
But the frame is also clean when I disable \hideSolution. In that case, texts
should be appeared.
What I want is the following:
If \hideSolution then
hide text and add more blank spaces
else
show full text and no more space.
endif
The full text for the students another for the lecture.
Is there a way not using \framedtext?
Thank you again.
Best regards,
Dalyoung
