MCI stubs

[Phone Box]

Hi,
I'm trying to get C# to talk MIDI to a drum machine. As soon as I can
get the MCI functions to compile I'm home and dry. Please can someone point
me in the right direction on how to do this? All I really want is to use the
calls in the DLL via C#. I have found code like this...

[DllImport("winm m.dll")]
private static extern long mciSendString(s tring strCommand,Stri ngBuilder
strReturn,int iReturnLength, IntPtr hwndCallback);
[DllImport("Winm m.dll")]

This sounds like a fairly common operation. I intend to add a series of
these definitions for the following functions...

midiConnect
midiDisconnect
midiInAddBuffer
midiInClose
midiInGetDevCap s
midiInGetErrorT ext
midiInGetID
midiInGetNumDev s
midiInMessage
midiInOpen
midiInPrepareHe ader
MidiInProc
midiInReset
midiInStart
midiInStop
midiInUnprepare Header
midiOutCacheDru mPatches
midiOutCachePat ches
midiOutClose
midiOutGetDevCa ps
midiOutGetError Text
midiOutGetID
midiOutGetNumDe vs
midiOutGetVolum e
midiOutLongMsg
midiOutMessage
midiOutOpen
midiOutPrepareH eader
MidiOutProc
midiOutReset
midiOutSetVolum e
midiOutShortMsg
midiOutUnprepar eHeader
midiStreamClose
midiStreamOpen
midiStreamOut
midiStreamPause
midiStreamPosit ion
midiStreamPrope rty
midiStreamResta rt
midiStreamStop

Many thanks

Peter.

Re: MCI stubs

Peter,

You are going to have to code these by hand, or find someone that
already did them. You might want to try http://www.pinvoke.net and see if
someone already created the definitions. If not, then I would suggest
contributing your method definitions once you create them.

Hi,
So far the following works...

using System;
using System.Collecti ons.Generic;
using System.Text;
using System.Runtime. InteropServices ; // DLL Needs this

namespace AlesisSR16
{
public class MciClass
{
[DllImport("Winm m.dll")]
static extern uint midiInGetNumDev s();

public static uint MCI_midiInGetNu mDevs()
{
return midiInGetNumDev s();
}
}
}

// Activated in an aboutbox handler
private void AboutBoxSR16_Ac tivated(object sender, EventArgs e)
{
uint a = MciClass.MCI_mi diInGetNumDevs( );
this.textBoxDes cription.Text = a.ToString();
}

Cheers

Peter.
