How can I make an automatic updater for my visual studio 2010 c++ application?

Question

How can I make an automatic updater for my visual studio 2010 c++ application ? I do not want any kind of advanced features. Any free application that can provide a notification that "A new version 1.2.2 is available" ?

Actually right now I just want only notification to the user not download the software or something like that.

When a user run the application then simple check the new version, if available then a message box or notification appears.

My idea is that the application simple check a "http://www.site.com/update.txt" file which has a number if number increment in future, then msg box appears that "a new version is available, Visit website" .. its simple but how can I check in VS2010 C++ ?

Answer 1

How about using ClickOnce deployment? I's very easy to use in C#, more complicated in C++, but MSDN tells that it is possible:

Sparkle is the best choice I found. Its amazing. Here you go http://winsparkle.org/

Answer 3

^{I don't know Windows, but....}

You could use some HTTP client library, perhaps libcurl, to issue a GET HTTP request to your http://www.site.com/update.txt URL.

But don't overwrite magically the binary executable.
