I am using System.Data.SQLite with a relatively uncommon

I've never heard of this language before; however, it sounds
like it hosts the CLR within its process?
I'm not sure. VEE is a graphical programming language
similar to NI LabView. There are a lot of things in VEE that
are beyond my ability to observe.
My application works fine when run on an internal or USB
thumb drive. However, if I try running it from a network
drive SQLite fails to load.
For the 2.0 .NET Framework, loading assemblies from a network
share can be complicated by trust issues.
If trust issues are the cause of my problem, would a C#
program targeting 2.0 also fail? If trust issues are
insurmountable would this be a case for using the GAC?
Since I do not see
any network share paths in your trace output, I'm not sure if
that is the case here.
There should be network shares in the trace output since I'm
running the program from the network. It should be looking
for SQLite in something like
b:\SomeNetworkFolder\MyAppFolder. Instead it's looking in
the VEE runtime executable path. I wonder if this is a
symptom of trust issues.
One thing that I'm noticing is that the successful load uses
the "LoadFrom context" and the failed load uses the default
context. I'm not sure how the VEE code loads the
System.Data.SQLite assembly (or other assemblies); however,
maybe try using the "LoadFrom context" when loading from the
network share as well.
I point and click on the assemblies I want to use in the VEE
IDE, and have no control after that.
Anyway, thanks for the help. I have a few things to look
into, and I may file support request with Agilent if I can
rule out all issues with my network.
