Is there any need to learn delphi7 ?

恕我无能，delphi7是指什么？

I think the answer is no. If you have time to learn some software development language, I recommend you to research C/C++ or Jave not delphi7.

no there is no need trust me its 100% bullshit. If i were u i would not even think about learning bullshit would i???
