Re: Replacing a running file programmatically

A way to do that is calling a function that does the termination, for

continue execution?
Perhaps "continue execution" was the wrong phrase to use.
However on the next run the IF statement would evaluate to
false as the current version would be the same as the version
on the server.
There is no mechanism in C++ to do that. You need to ask in the
newsgroup dedicated to your OS.
Damn. Strange though, eclipse can restart itself as can spybot after
updating..
Most applications do this, at least where I work. But an
application is almost never a single executable. The
"application" that the user invokes is almost always a shell
script, which invokes the binary, and takes charge of reinvoking
when it exits, it if this is desired.
And of course, just how you do this is platform specific, since
the scripting facilities available by default aren't the same
for Unix and Windows.
Maybe the answer is another exe that is started before exiting,
performs the move actions and then reinstates the original exe.
That is another possibility.
I would like to avoid this particular method if possible as it
adds (imo) more complexity to the program. As the original EXE
is the updater for a different program the code i am looking
for is so that the updater can update itself.
If there's a way to do this, it depends on the OS. (Under Unix,
for example, one of the exec() functions could possibly be used.
But as I said, a simple shell script is the usual solution.)
