i am new in WCF. once i was searching code for uploading file to web server by wcf. i found a code which uses message contract for file details. i just do not understand why people use message contract. according to that situation the coder can use data contract only instead of message contract....so why they used message contract is not clear.
here is the link of source code for file upload by wcf. just have a look and tell me can we use data contract for file information instead of message contract. give some few good situation when one has to use message contract instead of data contract. thanks
So for instance, my laptop is connected to a projector via VGA cable, is there a way to control when I want to display the laptop's desktop in the projector? I'm creating an interface in C# wherein if I click a specific button, the projector will display the laptop's desktop. Basically it acts like the Win + P function of windows.
If nothing else works, there is always the simple solution: have a neutral background to your desktop (an image of the presentation name, and your contact details perhaps) and then show a form on the second monitor (maximized) when you want the projector to display. Minimize it when you don't.

Well that is the obvious answer, but you also need to check that you are not falling off either end of your list. If your selected item in the above is the last or first in the list then your index could be set to -1, or 1 beyond the end, which would be incorrect.
