Problem I traced is
1) The SQL Command is "INSERT" instead of select command. Insert Command insert data into tables and return the number of records inserted.

2) DataReader returns object. You have to convert the same into the data type you want eg. code
{
object obj = dr.read();
Convert.ToString(obj);
}

SO YOUR REQUIRED CODE SHALL BE LIKE FOLLOWS
----
SqlConnection con = new SqlConnection("server=AAB;database=ab;uid=sa;pwd=pass");
con.Open();

SqlCommand cmd = new SqlCommand("SELECT * FROM myTable", con);
SqlDataReader dr = cmd.ExecuteReader();

while (!dr.IsDbNull())
{
Object obj = dr.Read();
label1.Text= obj.ToSring();
}
dr.Close();

---

try and reply.

Encrypting the docx file as a whole does not look like an idea to you? (Unless of course you are willing to write your own app to display the encrypted docx file).

Search Google for C# AES.

IPC

Hi.

I have a windows service. I want to write an (C# .net) application that users run to communicate with the service. There is no restriction on .net version but security is important. What solution do you suggest?

I did a bit of research and found out named pipes and LRPC are good choices among other technologies. However it looks like in .net we'd better use WCF which, for IPC, supports named pipes. But WCF seems to have a steep learning curve. So I decided to ask you before I start to learn it.

Thank you very much for you help in advanced.

I used WCF for exactly this purpose. There is a learning curve - mostly because of the number of configurable options exposed. I recommend "Programming WCF Services" by Juval Lowy - it's on Safari.

By the way, How was the performance? Does it support only named pipes for IPC?

I think there must be these information in the book but I can't wait to know them! Sorry. Blush | :O

Performance was fine. It supports everything from named pipes to https.

You need the ABCs: Address, Binding, Contract. You can mostly mix and match these - I think I used a tcp binding as I needed to support remote access.

Thank you so much Nick. Your help is really appreciated. And thank you again for the book recommendation. It's a nice book. I hope to be ready to code the communication part within a few weeks (or less maybe.)

Thanks for all the help. Rose | [Rose]
