System.Reflection.TargetInvocationException error

[paradoxdetected]

Hi all

thanks so much for all of your help over the last day or two, but I'm having some serious issues with this error.

I've googled and MSDN'ed and god knows what else, but I can't seem to find any concrete 'you're doing THIS wrong' help in english.

I know I'm a newbie, but this it hard. If anyone can shed ANY light on this I'd very much so appreciate it:

if you're able to look at this and go 'ah-ha!', then please shed any light you can on this.

Thanks so much,

What you need to look at is this:

InnerException: System.InvalidOperationException
Message="Cannot perform this operation while the recognizer is doing recognition."
Source="System.Speech"

This is the error that is causing the problem. When I Googled "Cannot perform this operation while the recognizer is doing recognition" I got this:

and also this:

So, you're going behind our backs to get help elsewhere, eh? ;-)

Anyway, check out the first link and maybe it will help you to figure this out.

Good luck!
