c# - Parameterized queries on iteration -

-

I am including web form in database and therefore using parameterized queries. I have a checkboxist. How can I repeat more than CheckBoxList, to create a insert statement for every check (multiple-to-many), and to keep this parameditized and killed at one time

< P> I enter this now: 

  string query = "resources (URLs, submitted_by, AUTHOR_NAME) values ​​(@url, @submitted_by, @author_name);"; Foreign Currency (Listed in the checkbox list 1). If (li.Selected = true) {query + = "INSERT IN"; }} SqlCommand CMD = New SqlCommand (query, conn); Cmd.Parameters.AddWithValue ("@ url", TextBox1.Text); Cmd.Parameters.AddWithValue ("@ submitted_by", TextBox2.Text); Cmd.Parameters.AddWithValue ("@ author_name", TextBox3.Text); Try {conn.Open (); Cmd.ExecuteNonQuery (); Label1.Text = "Added to database."; }

As you can see, it is incomplete any suggestions?

You can use LINQ to generate unique name parameters for each item in your archive , Then you can add the associated values ​​to later versions: 

  var builder = new StringBuilder (); The above listParams = CheckBoxList1.Items .Where (li = & gt; li.Selected) .Select (Lee, IDX => New {PhoneString = String.Format ("@ phone_id {0}", IDX), PhoneValue = GetPhoneId (Lea), ResourceString = String.Format ("@ource_id {0}", IDX), Resource Value = GetResourceId (li)}; foreach (various paramas in list paramours) {builder.AppendFormat ("Phone_sets (Phone_ID, in resource_id) Include values ​​({0}, {1}); "param.PhoneString, param.ResourceString";} SqlCommand cmd = new SqlCommand (builder.ToString (), cone); foreach (listParams on top) {cmd .Parameters.AddWithValue (param.PhoneString, param.PhoneValue); cmd.Parameters.AddWithValue (param.ResourceString, param.ResourceValue);}

I will add you I'm thinking that there is a way to be there, code_id, RESOURCE_ID from any ListItem - you can simply plug me where I go to placeholder Code> tasks.

Note: Switching to a stringbuilder - is better than creating a string with repeated + = < / P>

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).
