.NET Forum / .NET Framework / General / September 2005Auto update of programs.
Has anybody had any experience writing an auto update program that will check the internet to see if there is a newer version of the code out there and download it? It doesn't seem that complicated but I just wanted to hear from people who have done it if there are any gotchas I should watch out for. TIA - Jeffrey.

Untested Beta code that may or may not be released. I can assure you that this code is tested and that it will be in the release. http://msdn.microsoft.com/vstudio/productinfo/roadmap.aspx Apps in production within MS already use this technology. I speak from experience, it works just fine.

For example, I've looked at many of the "Application Blocks" and found installation and requirements to be restrictive and cumbersome ( requiring XP Pro in some instances ). Even if it 'works' and is 'almost ready' I'd stay away from it because Microsoft constantly twists and changes things before release. At that point he would be stuck with a lot of code dependent on something that doesn't exist. You can write an auto updater quite easily with a little bit of code that can call a web service and get version number. I'm writing just such code right now. There are built in methods to get version numbers from assemblies and calling assemblies -- just match those to an update version on the server to see if they need to be downloaded. Simple. >> I can assure you that this code is tested and that it will be in the >> release. [quoted text clipped - 23 lines] > > Simple. If you weren't such a notorious member of this forum, John, I'd engage in an actual lucid conversation about the pros and cons of "buy" vs. "build". Unfortunately, your reputation for attempting to start fruitless arguments rather than discussing actual points of concern precedes you by leaps and bounds. If you are worried about being tied to a particular interface in .Net 2.0, then encapsulate it with a facade pattern. That way, if it changes, only your facade changes. (Personally, I wouldn't be worrying, but worrying is such a personal thing... feel free to spend your time on this and any of a dozen other concerns, like how you are going to get your simple app to make sure that the file you are updating isn't being used by another user when you are updating it). --- N Signature--- Nick Malik [Microsoft] MCSD, CFPS, Certified Scrummaster http://blogs.msdn.com/nickmalik Disclaimer: Opinions expressed in this forum are my own, and not representative of my employer.

Nice FUD Nick. As soon as my arguments best yours, you resort to name calling. I offered very valid technical reaons -- you hid behind some vague 'technology' that is in beta, buggy and might not meet the persons needs. Scrape the MVP off your badge, dude...it's back to MSCE training for you. Nick, I don't see what is wrong that John, gives his opinion. He tells it directly how he thinks it is. You can read it as; it is just rude arguing without sense. You can read it as a warning to others and Microsoft that *he* wants more consistency. I keep it that he means the last. (While I don't agree with him, VS 2005 is a product still in its developing phase. That means for me every time evaluations of what you did and because you do that be open to renew it until the last moment of release) Just my thought, Cor Hi Cor, I would gladly engage with a conversation with you on this or any other issue. It is true that beta software has risks, and that using it comes with some concern. I suggested that the OP take a look at the beta software to see if it would fit. I didn't suggest that it was the only possible answer, or even that it applied to their problem... simply to take a look. Mr. Bailo has made some good contributions with some technical merit. For that, I credit him. In this thread, he's been OK. On other threads, including some recent ones, he has intentionally posted 'troll threads' where he will make an intentionally opinionated non-technical statement that he cross-posts to the linux advocacy group. As a result, I have no desire to engage Mr. Bailo in any kind of direct conversation, regardless of the merit of his statements. A person that I do not know gets a basic level of respect, that is theirs to lose. He has lost that respect.

So I need to make this happen automatically. I will probably go with either a Window's Web Service to check against the server or do something so stupid as download a 'version' file that tells me the current version of the software and if they are different I'll download the file. Thanks anyway. > Will the Click Once feature in Whidbey work for your situation? > http://msdn.microsoft.com/smartclient/understanding/windowsforms/2.0/features/cl ickonce.aspx [quoted text clipped - 7 lines] >> >> TIA - Jeffrey.
