Trouble adding comma to bar graph data using Windows Chart Class

I am using the library:
System.Windows.Forms.DataVisualization.Charting

and found I could format (with comma) for values > 1,000

with this line of code:
ca.AxisY.LabelStyle.Format = ("##,#");

But, I can't figure out how to get the data to display also with the comma.

Best I get is the following:

Here is the Microsoft reference document:

Using Microsoft .NET Framework Version 4.8.03752 I performed a [successful] FTP upload.  How do I compare the source and the target to verify they match?

I have a VB.NET 2015 program that has a Tcp socket Listener and client applications to send messages to workers by their ip address.
I need to be able to pick up a file from a directory and send the text files data to a client machine connected to the listener. The file name is the ip address. When the file gets put into the directory is when the listener will pickup the file and send it to the appropriate ip address. I can pickup the file but the message gets sent to all clients connected to the listener.  My code is below.

        Button3.PerformClick()

    End Sub

        If ServerStatus = False Then

There's a field in a table of a SQL Server database that doesn't except "NULL" but has a default value of "0".  The InsertCommand for the data adapter that vb.net automatically  generates doesn't accommodate this. If the field is left blank in the front end program, the update method of the data adapter fails with a message that the field can't be left blank.  It doesn't set it to the default value that is set in the SQL Server table.  What is the easiest way to get the data adapter to set the field to the default value when the corresponding parameter is null (from being left blank by the user)?
