Carl
Once again thanks - working on this for several days and getting nowhere
Here's the info you asked for. Note that I included the both GET subs in
their entirety even though this program only extracts limited info needed.
Also note
a) if I set the local machine Intranet zone permissions to "Full Trust"
program works without generating a policy exception
b)if I create a new zone with "Full Trust" and import the program "key" the
program works without generating a policy exception
Assembly - Security and Signing Follows:
'Sign the Assembly
'strong name key [MyProgram.snk] created with sn.exe. Key must reside
'in the same folder as the Visual Studio Project.
<Assembly: AssemblyKeyFile Attribute("MyPr ogram.snk")>
'
'Deploy the Assembly requesting FullTrust Permissions
'<Assembly: PermissionSetAt tribute(Securit yAction.Request Minimum,
Name:="FullTrus t")>
The two Get subs Follow:
1)Get System Info
'Use Windows API to get User System Memory Status
Public Declare Sub GetSystemInfo Lib "kernel32.d ll" (ByRef lpSystemInfo As
SYSTEM_INFO)
Public Sub Get_UserSystemI nfo(ByRef ProcessorType As String)
Dim SysInfo As SYSTEM_INFO
GetSystemInfo(S ysInfo)
Dim UserProcessorTy pe As String = SysInfo.dwProce ssorType.ToStri ng
ProcessorType = UserProcessorTy pe
End Sub
2)Get User Environment
Public Sub Get_UserEnviron ment(ByRef Name As String, ByRef OSversion As
String, ByRef MachineName As String)
'PROCESS
Dim UserProcess As Process = Process.GetCurr entProcess
Dim UserProgramName As String = UserProcess.Pro cessName

Dim UserPrivateMem As Long = UserProcess.Pri vateMemorySize

'it is running; it includes only the size of the

'The Base Module represents the static program code.
Dim i As Integer
Dim total As Integer

End Sub

Thanks for the reply
Following is a code snippet from my main sub. The policy ecxception error
which is picked up by the local machine arises at the first call to to
get
system and environment information.
The CAS then throws up the debug screen locally before the "catch" can
activate
code follows:
Public Sub Main()
'
'Allow XP style Forms to be viewed on User screen
Application.Ena bleVisualStyles ()
Application.DoE vents()
'
'Get the user and machine environment data
'
Try
Get_UserSystemI nfo(USER_PROCES SOR_TYPE)
Get_UserEnviron ment(USER_NAME, USER_OSVersion, USER_MACHINE_NA ME)
Try
'Windows 2000, XP
Get_UserMemoryS tatusEX(USER_SY STEM_MEMORYEX,
USER_AVAILABLE_ SYSTEM_MEMORYEX )
Catch ex As Exception
' Do Nothing if API call fails
End Try
'
Catch ex As System.Security .Policy.PolicyE xception
'
'if the user has installed the program on one computer within a
network
'environment and attempts to run the program from a different
machine
within
'the network then the system.permissi ons exception will be caught
here.
'
MessageBox.Show (Get_Msg("50019 ", "", "", "", ""), _
"Name", MessageBoxButto ns.OK, MessageBoxIcon. Error)
'
'terminate the program
End
'
Catch ex As Exception
'
'if the user has installed the program on one computer within a
network
'environment and attempts to run the program from a different
machine
within
'the network then the system.permissi ons exception will be caught
here.
'
MessageBox.Show (Get_Msg("50019 ", "", "", "", ""), _
"Name", MessageBoxButto ns.OK, MessageBoxIcon. Error)
'
'terminate the program
End
'
End Try
etc
etc
end sub
Mike,
That code looks like it should be working. Are your Get methods making
calls into another assembly? Is your .NET security configured correctly
for that application?
