c - Child Window with Limited Resizing -

-

I want to create a child window that takes all the place on the left side of the main window, but its minimum width is 128 pixels. Also want it to be shaped, but only on the right edge, and make sure the width stays at a minimum of 128. Make a hair window with these styles: WS_EX_STATICEDGE, WS_SIZEBOX | WS_CHILD | Handling WS_VISIBLE and WM_NCHITTEST messages, I can only resizable it on the right edge, but I can not do this, so the minimum width remains at 128. Can anyone tell me how to do this or if there is any other window class which takes care of all of this?

You must handle messages that resize windows: WM_POSCHANGING , WM_SIZING , WM_SIZE and WM_POSCHANGED . The best user experience is to handle.

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).
