Help, Strange "An exception 'System.TypeInitializationException'has occurred in ... error.

[nick]

The program runs well on Local harddisk. But it always popup the
exception if I run it on Netware mapping disk. After debugger say there
is no source code on the exception. Also the following error shows. Very
strange.

Unhandled Exception: System.TypeInitializationException: The type
initializer fo

I found the following statement cause the problem on Netware mapping
driver only (Local hard disk no problem):

static OleDbConnection conn = new OleDbConnection(connStr);

 

[nick]

After I move the statement

static OleDbConnection conn = new OleDbConnection(connStr);

from class member to function variable.

OleDbConnection conn = new OleDbConnection(connStr);

The error changed to:

"An unhandled exception of type 'System.Security.SecurityException'
occurred in Unknown Module.

Additional information: Request failed."

Very strange. Why it occur when run the program on netware mapping drive?

All code under .net framework runs with a set of rights. The code
started from the local harddisk has full rights, while code, loaded from
a network is restricted. You can give more permissions to some assembly
using AdministartiveTools/Microsoft Framework 1.1 Configuration or
Microsoft Framework 1.1 Wizards.
