[DotNetDevelopment] log in page c#

[james]

Hi,

I'm currently working on a log in page for a windows app.

All i want to do at this stage is check the entered username and
password against the values held in the database.

currently I have

 SqlDataReader read = null;

string query = "SELECT * FROM [User] WHERE username = " + enteredUser;
SqlCommand myCommand = new SqlCommand(query, conn);
read = myCommand.ExecuteReader();

//and just to check the values

if((string)read["pass"]==txtPass.Text)
                {
                    MessageBox.Show("worked");
                }

does this look like it should be working? Its not bringing back any
values when i enter details i know exist in the database.

thanks
