Answer 1

ClickOnce deployment does incremental updates. When you deploy an update, if the date/time stamp and hash of the file are the same as the last version, ClickOnce copies them from the cached version into the new version instead of copying them across the internet.

If you have several projects in one solution, ClickOnce will deploy each of these every time, because they are recompiled and rehashed when you build the solution. BUT if you have projects that you do not think will change a lot, you can put them in a separate solution, build them, and include the dll in the main application. Then it won’t be rebuilt and rehashed every time you publish, and won’t be copied across the internet again.

As for starting from the internet, you can specify that the application be run online-only, which requires that the user be able to connect to the deploymnet manifest (.application file) and be able to check for updates every time he runs it.

Note that most people set ClickOnce to check for updates and install them before running, which ensures the customer is always running the most recent version.

I’m not certain what this means: “I need to update of the program does not needing stop”.

If you want to update a ClickOnce application without forcing the user to close it, you can use the programming APIs to check for an update and install it, but you will have to restart the application in order to install the updates. (Application.Restart()).
