c++ - PostMessage: Access Denied -

-

The application will receive the message from all the processes of the system. The message is sent using a postage call, which gives an error (5, access denied).

The code works correctly on Windows XP SP2, but only Windows 7 receives the message itself, which should be considered for receiving messages from each application.

Reading the post message document, I can read:

When a message is blocked by the UIPI, the last error is retrieved from GetLastError 5 (Access denied).

But in reality it does not say how this "UIPI" works, how do I do it?

You can allow your program to get a specific message using the function.

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).
