Perhaps, but that's why one should be a little more descriptive. To the original poster, the documentation for the System.Data.SqlTypes (if that is, in fact, what you meant) explains it quite clearly: The System.Data.SqlTypes namespace provides classes for native data types within SQL Server. These classes provide a safer, faster alternative to other data types. Using the classes in this namespace helps prevent type conversion errors caused in situations where loss of precision could occur. Because other data types are converted to and from SqlTypes behind the scenes, explicitly creating and using objects within this namespace results in faster code as well.

That's a pretty dumb restriction - knowing an IP isn't a problem; it's making sure that the server is secure that is. Even if the server establishes a connection with the client, it's easy to determine the IP address (it's in the TCP/IP headers!). But you probably can't do anything about that. If both the client and server are on the same LAN, you can use a multicast group. See the class documentation[^] for the MulticastOption class in the .NET Framework SDK for more details and a client/server example. This uses UDP to send datagrams (connectionless IP, unlike TCP) to a multicast IP address (reserved range; it's not the server's IP). Everyone in the multicast group can receive the message and process it. Microsoft MVP, Visual C# My Articles

I agree with this. However what sort of design are you talking about? User Interface design, the design of the application, data base design and so on. Personally, I feel that things like this are massively under-represented... Which probably just goes to show that most people just don't give a sh1t about the subject. :( "You can have everything in life you want if you will just help enough other people get what they want." --Zig Ziglar "On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?'

The Win32 calls would only come in if you need to have the main form, its sub-form, and then the 3rd level sub-form all showing a title bar that indicates it is active. I'm not really if there is anything else to the base MDI document behavior. To add a form as a child of another form, make a constructor to the (sub)form class which takes the parent as a parameter. Then, in that constructor, set TopLevel to false, and Parent to the parent form. It would look like this: public MyMdiForm(System.Windows.Forms.Form parent) { InitializeComponents(); this.TopLevel = false; this.Parent = parent; } To handle the look that needs multiple forms to display as active, check this[^]out.

I've never tried to keep a window position from going too far to the top or the left, but the WM_GETMINMAXINFO message and the related MINMAXINFO structure were designed to limit sizing and maximized window positioning. Check that out. It may be the solution you need. John "You said a whole sentence with no words in it, and I understood you!" -- my wife as she cries about slowly becoming a geek.
