Help Please with textstring !!

I have started to use C++Builder to build some programs.
But I'm having startproblems.

I have made a button, and when it is pushed I has to write out
some text, but nothing happens, as you can see in the code
I'm trying some diffenrent things.
calc() is a C funktion. It's only making a calc, and writing som text too.
What can I do to make this work ??
