Aladdin Etoken Pro, C#
in [Device Drivers]
|
From: zoltan_papp_123456 on 6 Nov 2006 10:07 OS : Windows XP Professional Environment : MS Visual Studio 2005 Language : C# Hi, I am trying to write a windows application using C# that accesses the Aladdin Etoken Pro USB device. (www.aladdin.com) I am using [DllImport("eToken.dll")] to import functions and i am using MarshallbyAttribute to import types/arguments of the functions. 1, What happens when the unmanaged function in the dll that i am importing has data types that do not exist in the class under C# ? Do i use the MarshallbyAttribute function or how does it work ? I tried to access unmanaged datatypes using the following syntax : [DllImport("eToken.dll")] public static extern DWORD etCreateTalker ( MarshalAsAttribute(UnmanagedType.DWORD), MarshalAsAttribute(UnmanagedType.LPCTSTR),....... The following code is not proper though since the UnmanagedType function does not return the LPCTSTR type. So i would need something that is capable of bringing over types that are not returned by the UnmanagedType function. etCreateTalker looks like this : DWORD etCreateTalker ( LPCTSTR lpszReaderName, LPHTALKER phTalker, DWORD dwFlags ); Any help welcome ! I spend my whole day on this so i want to get going. Seems like that there aren't a lot of people out there whom want to program the etoken in C#. Zoltan.
