wpf - Binding the content of a Span -

-

I have a window that displays the text, there are two parts of the text: first fixed, while the other The need to have the contents of the dependency property declared on the window.

I considered using a spelled text block, the first of which is the definitive content and from which there is variable content in the other, but on the SPAN class, I can not see anything clear Dependency dependent will depend on dependencies.

I am currently using two label stacked one side but it is ugly and if I want to retrieve the contents of the entire text block (as I did it, then that device Displaying tooltips in that the window is too large to display the entire text block) does not help me.

Can anyone help me solve this seemingly simple problem? Thank you.

If you are using .NET 4: 

  & Lt; TextBlock & gt; & Lt; Run text = "fixed:" /> & Lt; Run text = "{binding variable}" /> & Lt; / TextBlock & gt;

Before .NET 4, play 's text property was not a dependency property.

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).
