InvalidOperationException in IEExec.exe

[Alexey Kouzmitch]

I am trying to make my application into a smart client app. When I put in
the Url in, i get a CLR crash pop-up which says that a
System.InvalidOperationException has occured in IEExec.exe.
any ideas?
I set the intranet permissions to full thorugh the .net permissions wizard.
Is there particular code that could be causing this?

Some of the things i do:

I get assembly version to put in the title of the window.
I access SQL server.
My connection string is saved in the .config file
I reference shdocvw.dll to get an imbeddable browser, but it didn't work
even before i did that.

thats' about it

Thanks in advance.

It also says that :

The key 'ConnectionString' does not exist in the appSettings configuration
section.

So itr seems like the problem is related to reading the information form the
config file which is in the same directory as the app on the server and i
can get to it by typing in the direct url to it.
