.net - How do I make SqlServerCe accessible from my C# app? -

-

I was just playing with database in C # 2010 Express and 'system.Data.' The complete thing showed me the system as an alternative to the SQLSCECCEC. Not sure what I did, but when I created a new app and added 'line using system'. Data.SqlServerCe; 'I got a "SqlServerCe is not present" error I tried to add some references but still does not work. Actually, whatever I am trying to do is connect to any database, but I still do not I could find that all samples do not know me, I do not know. I'm trying to connect the connection string with the SqlConnection by setting it to what I can imagine, but I get the errors I installed the SQL Server compact version, and I think I have the SQL Server (normal version?) Please feel disappointed! I want that very, very simple. I want a data table, I do not care where or how I store it because there is only one program that will use it, it is my program, and able to do SQL queries on it. Actually I do not even need to save it after the program is closed. If I can do SQL queries on them, then I will only use a datatable or 2D array. Please be great if you can give me a sample

If you have any error using that statement , Then you have to add the reference of that assembly.

On my XP box, its location is: 

  c: \ program files \ Microsoft SQL Server Compact Edition \ v3.5 \ Desktop \

You see that using VS2010, simply change 3.5 to the directory name with 4.0 .

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).
