Declare Function auxSetVolume Lib "winmm.dll" Alias "auxSetVolume" ( _
   ByVal uDeviceID As Integer, _
   ByVal dwVolume As Integer) As Integer

ok, so in .net i need to convert all Longs to integers?.. (sorry im new to .net) anyway ive managed to convert most of the code in that example on AllApi.net except this:

 

Private Type AUXCAPS
      wMid As Integer
      wPid As Integer
      vDriverVersion As Integer
      szPname As String * MAXPNAMELEN
      wTechnology As Integer
      dwSupport As Integer
End Type
Private Type VolumeSetting
   LeftVol As Integer
   RightVol As Integer
End Type

 

....could someone please help :)

EDIT: oh and also As Any, which seems to have been removed in .net..

 

    Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByVal hpvDest As Any, ByVal hpvSource As Any, ByVal cbCopy As Integer)

 

 

I have a strange feeling this isnt going to work even when i have converted it :P

You'll need to define mutiple overloads of RtlMoveMemory in many cases.

 

Most of your other API related questions are answered in VB.NET: Platform Invoke.
