[cpp-netlib-devel] Dispatch Table Example

[Divye K. <div...@gm...>]

Hello all,
   I've just added a dispatch_table example to the repository. Please have a
look at the code and suggest any improvements.

While testing this example, I came across an oddity. I am using the same
functions as the http_client example. However, when I try to run
dispatch_table.exe, I need to provide it elevated privileges on Vista. The
same is not needed for http_client.exe. Why so? Any ideas?

The .exe name is probably triggering one of the UAC heuristics; the OS
checks the filename of every launched executable, looking for keywords
that give it away as an installer. Apparently "patch" is one of the
trigger words [1], so "dis*patch*_table.exe" is incorrectly classified
as requiring elevation.

Best bet is probably to change the name of the .cpp file and/or .exe.
The only alternative I know of is to add a UAC manifest either
embedded or side-by-side, but that complicates build and deployment
significantly, compared to the current...

Sweet! Which branch did you put it in?

I think it's because you're using Vista... Try it in Linux instead. :P

But seriously, I think this is not something we might need to worry
about. If it works even with elevation, then I think that's good
enough for me. :)

Maybe I really should ;-)

You're absolutely right. Changing the name of the executable removed the
need of the UAC elevation request.
Thanks :-D

Any suggestions for alternative names?

Hmm, that's hard... Some wise man said at one point to name things
after what problem they solve, not after how they do it (paraphrased
:) -- maybe that's a lead...?

 dynamic_methods?
 datadriven_methods?
 method_table?

I don't have any obvious winners :)
