DLL Win32 types in C# ??

[EdgarBM]

Hi, does any one knows where can I find extense documentation about parameters type changing between unmanaged Win32 DLLs and NET managed code calling? ...I'm trying to call unmanaged code DLLs and I have problems of Null Reference Exceptions (in this first step, later I'll surelly have problems of type incompatibilities) Please, give me any information you can. Thank you in advance, Edgar Edgar Berengena Moreno Software Engineer Appeyron Research

MSDN gives you most of the answers. Have a look at Interoperating with Unmanaged Code[^] Like Eric answered my post, its best to give a specific example and to work on that. In the unmanaged world not all things are equal. Also to make code CLS-Compliant stick to signed types. Hope this helps :) MYrc : A .NET IRC client with C# Plugin Capabilities.
