Dynamic Form in Different Application Domian

[mattyboy2000]

Hi. We've designed our application to dynamically create and call forms using a Different Application domain. We've almost got it working apart from when i want to run a sub that we created ourselves. The reason we are doing this is for the application to first look in the G:\prod\Comp\DLLs folder and if it can't find the DLLs there it will look in G:\eM1\Core\DLLs.

Dim objDomain As AppDomain

Dim objEvidence As Security.Policy.Evidence
Dim strApplicationPath As String

'Create a new domain and run the programs from there
objEvidence = AppDomain.CurrentDomain.Evidence
objDomain = AppDomain.CreateDomain("NewDomain", objEvidence, "G:\", "", False)

objDomain.AppendPrivatePath("prod\Comp\DLLs&quot
objDomain.AppendPrivatePath("eM1\Core\DLLs&quot

Dim frmLogin = objDomain.CreateInstanceAndUnwrap("M1Main", "M1Main.frmLogin&quot

' Hide the system picker and show the login form
Me.Hide()
frmLogin.setdata(Me)

CType(frmLogin, Form).Show()

It all works apart from the Line highlighted in red.

we get the message:

System.MissingMemberException: Public member 'setdata' on type 'MarshalByRefObject' not found.

at SystemPicker.frmMain.ClickedConnectButton(Object sender, EventArgs e) in G:\M1.net\Development\Sourcecode\GlobalM1\SystemPicker\frmMain.vb:line 225


If you have any ideas please reply.

Thanks
