The things that you have to do to protect your application

time to read 1 min | 67 words

The following is NHProf’s Main method:

Each of the currently existing conditions (and I am pretty sure that they will grow) is there because of bug reports from the field.

It gets… interesting, sometimes, the things that user do to my poor app.

Yeah it's a much different world than corporate clients that's for sure. The precautionary steps required are ten-fold in order to prevent an avalanche of false positive bug reports and associated problems.

I say, bind 'em up and lock 'em down. If your product still runs then your user will have a pleasant experience and be grateful to you, otherwise barf early and often otherwise the user will falsely cuss you like they do Microsoft.

I don't think you should do that - simply close the app without any notification for the user.

You should output a message telling a user why you are closing.

Krzysztof,

The Assert is also responsible for alerting the user

Ayende, not surprisingly, at the early stage of NDepend I wrote a similar post. But we try to go further by making sure all assemblies are here with all correct version in all correct location:

Yip, I've done similar assertions, as well as doing permission assertions.

e.g. Try running NHProf under Intranet/Internet Zone policies.

Hmm wouldn't reflector + deblector + reflexil make it trivial to bypass this? or i'm missing something?

Set,

Please read it.

Then guess about why I need it

Ahh nevermind i thought it was some kind of assert to "protect" your files in addition to your licensing scheme. I should go to sleep :x

I wouldn't bother at all to be honest. If someone is going to delete files I would let the app crash.

Maybe the unhandled exception dialog could suggest re-installing the file and if the problem persists they should send the bug report on to you.

Peter,

You do realize how many support calls a good error can save you?

Oren - yes I do realise how many support calls a good error can save :-)

So you realize why it is important to try to reduce them :-)
