exe file replace using QProcess

Ok. that makes it easier to get it to close. :)
Will user check for update from inside the program or how will that happen?
(if i may ask)

[4j1th]

@mrjj When the app starts it checks for update if available-> ask for update permission(user) -> invoke the updater using QProcess -> as you said close the app -> download and replace the exe

@mrjj Qt installer framework can replace a running exe and dll I don't know how!

There is a link to an article that talks about this problem and possible solutions. http://www.catch22.net/tuts/self-deleting-executables on Windows.

I, personally, would try to keep this sane. A separate updating utility that closes the original program and replaces or removes whatever should be replaced or removed is probably the safest thing to do.

I completely agree!

Hi,

One possibility would be to use the Qt Installer Framework that, AFAIK, has an updating functionality

Do not worry
he is not planning on overwriting the exe from WITHIN the exe :)
Even @Rondogs link is pretty interesting,
it does indeed smell of a complex way of shooting your foot off :)

@SGaist
tried qt installer framework but I don't think it can help the auto updating, launch a topic on this please see this link
