I have a slight problem inserting the proper result into an MS-SQL table. The result should be <14> however all I get is PRE. BTW, the SQL command is not broken appart like you see it on this limited width posting..........

I thought using single quotes desiganted a 'string'? Help........


string pattern1 = @"(<\d{2,3}>)";

Regex r1 = new Regex(pattern1, RegexOptions.Compiled);

Match PRE = r1.Match(stringOfData);
{
try
{
connection1.Open();
SqlDataAdapter1.SelectCommand.CommandText = "INSERT INTO
tblMyUdpServer (col_PRE) VALUES ('PRE')";
SqlDataAdapter1.SelectCommand.ExecuteNonQuery();
connection1.Close();
}
catch(SqlException error)
{
MessageBox.Show(error.Message.ToString());
}
listBox1.Items.Add(PRE.ToString());
}
}

try this sql statement instead:

"INSERT INTO tblMyUdpServer (col_PRE) VALUES ('" + PRE + "')";

You're concatenating strings to produce a sql statement.

If that doesn't work, try this:

"INSERT INTO tblMyUdpServer (col_PRE) VALUES ('" + PRE.ToString() + "')";

just an fyi, please try to use the parameter object to pass values into an insert statement.  A parameter will take care of special characters for you.  Otherwise you are setting yourself up for a possible SQL injection attack.

see the bottom of this article for some info on using parameters:
