i have a simple (1 form) Winforms VB.net 2003 app and am migrating it to
vb2005
testing both on the same box...
if i run the 2003 version it works correctly, but the 2005 version fails
when attempting to connect to a SQL Server database.
looking at the connection object after the attempt i have an exception
object in the WorkstationID:-
"Request for the permission of type
'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089' failed."
in the 2003 version i have a valid workstation id
the code to this point is identical
StackTrace " at System.Security.CodeAccessSecurityEngine.Check(Obj ect
demand, StackCrawlMark& stackMark, Boolean isPermSet)
at System.Security.CodeAccessPermission.Demand()
at System.Environment.get_MachineName()
at System.Data.SqlClient.SqlConnection.get_Workstatio nId()"
any ideas?

not strictly true, the converted app was still in cb2003 format ie one file
for the form, whereas the the one that works has a vb2005 styel partial class
setup, can not see wy it should make a difference but?
