Missing .NET and Exceptions

[John Bowman]

Hi All,

I've been reading about Application.ThreadException,
Application.SetUnhandledExceptionMode &
AppDomain,CurrentDomain.UnhandledException. I'm trying to determine if there
is a mechanism where if the .NET framework is missing, is there any way at
all to gracefully catch it in my code and inform the user of what's wrong.
Is this even possible? If so, how can I catch it and nicely inform the user
of the problem - Microsoft's "The application failed to initialize
properly..." message is basically useless to a user. If it's even possible &
anyone has any code to share, I'd be much appreciative.

TIA,

John,

It's impossible, since the code you would write is managed code, and
without the framework installed, managed code won't run.

You would have to create an unmanaged stub to check for the existence of
the framework, and then show the appropriate message if it is not installed.
If it is, then you would just create a new process and run your managed
executable then.

Hi,

Not, unfortunatelly all those events, classes, etc that you mention, well
they are part of the framework in tehr first place :)

You would have to create an unmanaged process to detect the presence of the
framework.

Or convince MS to create another message :D
