Hi!

I'm trying to find out how to avoid having to manually declare all of
the WinAPI C functions and structs before using them in VB.NET.

I'm getting familiar with VB.NET 2005 and thought I should start by
doing a copy of a little program I made in C++ years ago. That program
used a lot of the MIDI WinAPI functions (like midiInGetNumDevs and
midiInGetDevCaps). I've searched the help, net and newsgroups, but from
what I understand, I need to declare the functions and structs manually.
Is that really how it's supposed to be or is there a .NET
equivalent/wrapper for all the functions and structs?

I found a link to a file (for VB6) that seems to be declaring a lot of
the things I need, but when I search my newly installed VS 2005
environment, I dont find anything similar, only for VC (...\Microsoft
Visual Studio 8\VC\PlatformSDK\Include\MMSystem.h), and two more files
for SmartDevices.

Any pointers in the right direction whould be greatly appreciated!

Kind regards,
Ted Lyngmo

Well you can look at places like http://www.pinvoke.net to see if
someone has done the work already.
