• .NET Development Difference between Sockets and TCPlisterner-TCPClient

  Hi, I'm new to sockets and I can't understand the difeerence on creating sockets using : New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) or using the TCPListener and TCPClient classes. Any help will be appreciated.. Thanks. Ubercoder The Socket class is not protocol specific and provides an abstraction for network communication.  This way you can write code using a single set of semantics (Bind, Connect, Send, Receive, etc) regardless of the network protocols you wish you use.  For example, you can write a Sockets-based application that uses IPv4 or IPv6&n ...Show All

• SQL Server Conditionally adding a column to my custom component (part 2)

  A month or so ago I instigated this thread- http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=243117&SiteID=1 which talked about how to conditionally add a column to my component depending on the value of a custom property. If the custom property is TRUE then the column should appear in the output (and vice versa). Bob Bojanic said I should use the SetComponentProperty() method to do this and that is working pretty well. However, it bothers me that SetComponentProperty() could be called, the column will then be added, and then the package developer could press 'Cancel'. In this instance the value of my custom property would be inc ...Show All

• Visual Studio Web Form Designer: How to activate it to allow Menu Paste to add control at design time

  Hi all. I have a web form displayed in my IDE. I have created an 'HTML Format' clipboard item say representing a Label control. This is done via a dialog so the web form does not have focus. How do I programmatically 'click' on the web form surface (after closing my dialog) which in turn will activate the IDE Paste button, which I can then invoke to paste the control from the clipboard. I have tried SendMessage, and other api calls, to the various window objects that appear to be the right ones, but I cannot get the form to activate. Simply clicking on the form manually works. This must be solvable. Thanks for any assistance. ...Show All

• SQL Server Will IP Change cause problems?

  The IT department at my company is doing work in our server room and is planning on a few changes, among them changing the IP addresses of our servers. Will this cause any problems with SQL Reporting Services or our existing reports aloha, Jdolier This depends on how the connection strings for your data sources are set up. If you reference the server by name and the names are staying the same, then there will be no problem.  If you reference the server by IP Address then you will have to change the connection string in the data sources.
