MIDI Input API call

I'm using Visual Basic 5.0 (Pro) and want to be able to use the MIDI input API call (specifically the midiInOpen function).

Can anyone help me with this? I've got MIDI Output working fine (exceptionally well, in fact), and I know I can get the Input working as VB5 supports DLL callbacks, but I don't really know where to start!

Thanks!

Hello, I think I have an answer to your question...

Insert a module and then paste the following in the module. This will load the function MidiInOpen. Put this code on one line.
--MODULE--------------------------------------------------------------
Declare Function midiInOpen Lib "MMSYSTEM" (lphMidiIn As Integer, ByVal udeviceid As Integer, ByVal dwCallback As Long, ByVal dwInstance As Long, ByVal dwFlags As Long) As Integer

Public Const MCI_MODE_OPEN = (MCI_STRING_OFFSET + 18)

Public Const MCI_MODE_PAUSE = (MCI_STRING_OFFSET + 17)

Public Const MCI_MODE_PLAY = (MCI_STRING_OFFSET + 14)

Public Const MCI_MODE_RECORD = (MCI_STRING_OFFSET + 15)

Public Const MCI_MODE_SEEK = (MCI_STRING_OFFSET + 16)

Public Const MCI_MODE_STOP = (MCI_STRING_OFFSET + 13)

Public Const MCI_MODE_NOT_READY = (MCI_STRING_OFFSET + 12)

Public Const MCI_LOAD_FILE = &H100&

Hi,

Sorry - I'd already got that far, and could call the procedure successfully (returned a non-error value) but I haven't been successful in receiving the callbacks from it, even though I used the AddressOf [function] operator when calling it.

Have you/anyone managed to do this with VB5 yet?

Thanks!
