Is this Correct Gurus?

[David Hanson]

Guys,

Check the class at the bottom. I am atrying to establish a GPRS connection
but I must be doing something wrong. Can someone tell me how I am supposed
to create a GPRS connection using this class as I get System.NotSupported
each time I call CConnMgrEstablishConnection. Some help on this would really
be appreciated.


Imports System.Runtime.InteropServices
Public Class ConnMan
Private Const LocateDll As String = "coredll.dll"

Public Structure CONNMGR_CONNECTIONINFO

The structure must be passed ByRef

Ok Alex I have changed this but still get the same problem,

Do you know what i must set the structure variables to?

Hi All

We have a Toshiba 3370 PDA that does not seem to run .NET apps.

We think we have installed the right framework and have tried SP1 as well.

Does anyone here on the group use this sort of device for .NET development.

It may be a fault with the device but it could be the framework.

Thanks
