Delphi, olevariants and arrays of strings -

-

I have an object object that is created with (simple verion) 

  Obj: = CreateOleObject ('foo.bar'); Obj.OnResult: = DoOnResult; Process TMyDM.DoOnResult (Res: olevariant);

Whatever works, the race variable has a function string [] GetAns () which calls this way 

  var Ans: array of strings; Start ans: = Res.GetAns; End;

Which works again .. except sometimes an array is returned, and then an exception is thrown.

As a temporary solution I have left the block and wrapped it in an empty triangle, which I know bad I VarIsArray (Res.GetAns) < / Em>, but the result is still zero if it is still working

What is the correct way to check for the correct result?

ps I have no control over object objects

< P> Christopher Function

Process TMyDM.DoOnResult (Res: olevariant); Var ans: Wire array; If it does not start then VarIsNull (Res), if not VarIsNull (Res.GetAns) then start ans: = Res.GetAns; // the end of your luggage; End;

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
