VS 2010 Remove Lines From Textfile?
Jun 19, 2012I have two text files and each text file has various columns (each column is separated by a tab " "), now some of the fields in column1 text file2 match the fields in column1 text file1. What I'm trying to achieve is to remove every row in text file 1 where the field in column1 matches the field in column 1 textfile 2 - is this possible?I have used some basic coding in the past to remove certain lines, but nothing as complex as this.

VS 2010 Saving Changes (textfile) On Form Closing
Apr 7, 2011I'm sending a message on FormClosing(...)... This works ok. However... I have multiple tabs with a textbox or rtb, in it. When I change the text, whatever, it is modified. Now, when I close the app a messagebox appears that some of the textboxes or rtb's have been modified. This message is shown for each textbox-rtb-control. Which means, that when I have changed something in 4 different rtb's or textboxes I get the message 4 times. How do I change that to only one time?

VS 2010 - How To Insert New Row Into SQL Server Table
May 8, 2012I'm trying to insert a row into a SQL Server table.
Using this...
cmd.CommandText = "INSERT INTO MyTable (firstname, lastname) VALUES (@firstname, @lastname)"
cmd.Parameters.AddWithValue("@firstname", "bob")
cmd.Parameters.AddWithValue("@lastname", "jones")
cmd.ExecuteNonQuery()
I get an error saying:
ERROR [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Must declare the scalar variable "@firstname".
But if I use this...
cmd.CommandText = "INSERT INTO MyTable (firstname, lastname) VALUES (?, ?)"
cmd.Parameters.AddWithValue("@firstname", "bob")
cmd.Parameters.AddWithValue("@lastname", "jones")
cmd.ExecuteNonQuery()
...it works fine. What do I need to do to make the first example work? I don't understand what the error message is telling me. How do I declare a "scalar variable"?
