c# - already an open DataReader associated with this Command - when I'm not using datareader? -

-

I am getting an error that an open dataarder is associated with this command when I am not using a datesterer (Though probably the executereader is the same thing) If I do not have a stockman, then how do I close it? Using 

  (SqlConnection conn = new SqlConnection (ConnectionString)) {SqlCommand cmd = new SqlCommand ("spSelectAllTypes", Connecticut); Cmd.CommandType = CommandType.StoredProcedure; SqlCommand cmd1 = New SqlCommand ("spSelect AllTripA", conn); Cmd1.CommandType = CommandType.StoredProcedure; Conn.Open (); // checkbox list cbTransportType.DataSource = cmd.ExecuteReader (); CbTransportType.DataBind (); // dropdown list ddlTripTypeA.DataSource = cmd1.ExecuteReader (); DdlTripTypeA.DataTextField = "TripType"; DdlTripTypeA.DataValueField = "TripTypeID"; DdlTripTypeA.DataBind (); }

I just want to be able to have a bunch of dropdown list in an open connection database. (Before each open and closed for each control)

Execute Reader Return an open data reader You should really settle that before the connection is closed, although I'm not sure how it will look in relation to using it as a data source.

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).
