my code has changed....i am now able to do everything i want from it...but i am just having a small problem...
When i press the midi key of my controller it plays the note and when i unpress it it also plays the same note!
I have tried the .StopMIDINote() function but i do not know where to insert it?!!! If i was using a button i would know..mousedown play..mouseup stop..but i am using my MIDI hardware keyboard!
Below i show the code....if you have some advice i would appreciate it?!!?!?
Thanks You!

On the page you linked in another post (Visual Basic MIDI Piano[^]) there are these two subs which I assume are still somewhere in your code:
Private Sub Down(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseDown, Button2.MouseDown, Button3.MouseDown, Button4.MouseDown, Button5.MouseDown, Button6.MouseDown, Button7.MouseDown, Button8.MouseDown, Button9.MouseDown, Button10.MouseDown, Button11.MouseDown, Button12.MouseDown, Button13.MouseDown, Button14.MouseDown, Button15.MouseDown, Button16.MouseDown, Button17.MouseDown, Button18.MouseDown, Button19.MouseDown, Button20.MouseDown, Button21.MouseDown, Button22.MouseDown, Button23.MouseDown, Button24.MouseDown
Jazz.MidiOut(&H90 + chan, Note(sender), 100)
End Sub
Private Sub Up(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Button1.MouseUp, Button2.MouseUp, Button3.MouseUp, Button4.MouseUp, Button5.MouseUp, Button6.MouseUp, Button7.MouseUp, Button8.MouseUp, Button9.MouseUp, Button10.MouseUp, Button11.MouseUp, Button12.MouseUp, Button13.MouseUp, Button14.MouseUp, Button15.MouseUp, Button16.MouseUp, Button17.MouseUp, Button18.MouseUp, Button19.MouseUp, Button20.MouseUp, Button21.MouseUp, Button22.MouseUp, Button23.MouseUp, Button24.MouseUp
Jazz.MidiOut(&H80 + chan, Note(sender), 0)
End Sub
Looks like it's supposed to start playing a note on KeyDown and stop playing it on KeyUp, without a predetermined duration, which you seem to have added. So I'm guessing all you need to do is to either remove the "Up"-sub and the event-wiring for it or comment out the single line it it. If it doesn't work then I have no idea.

I think the solution is somewhere in these lines of code:
Dim DataByte1 = (dwParam1 And &HFF00) >> 8
m.PlayMIDINote(DataByte1, 127)
If i leave like that, when i press the key of my MIDI Controller the note plays and when i unpress it it plays again!
But if i set it like this:
Dim DataByte1 = (dwParam1) >> 8
m.PlayMIDINote(DataByte1, 127)
It only plays when i unpress the key....
Well.... it is the opposite of what i need...i need it to play when i press and silent when i unpress!!

In the code you linked a note gets played by a mouse left click. You say you play notes by pressing keys but I don't see any of that in your code. Can you show the code that handles key presses?

This is all the code i have now....plus the clsMIDI module:

Public Class Form1
Dim m As New clsMIDI

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
FillInstrumentCombo()
If midiInGetNumDevs() = 0 Then
MsgBox("No MIDI devices connected!")
End If
Dim InCaps As New MIDIINCAPS
Dim DevCnt As Integer
For DevCnt = 0 To (midiInGetNumDevs - 1)
midiInGetDevCaps(DevCnt, InCaps, Len(InCaps))
ComboBox1.Items.Add(InCaps.szPname)
Next DevCnt
End Sub
Declare Function midiInOpen Lib "winmm.dll" (ByRef lphMidiIn As Integer,

Dim duration = CInt(cboduration.Text)
m.NoteDuration = duration
End Sub

End Sub
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
midiInStop(hMidiIn)
midiInReset(hMidiIn)

When i press the MIDI keyboard keys it plays..but when i unpress it it plays again...i would like it to play only when i press!
This is the code i am using for it to play (check underlined):
Function MidiInProc(ByVal MidiInHandle As Int32, ByVal wMsg As Int32, ByVal Instance As Int32, ByVal wParam As Int32, ByVal lParam As Int32) As Integer
TextBox1.Invoke(New DisplayDataDelegate(AddressOf DisplayData), New Object() {wParam})
Dim DataByte3 = (wParam And &HFF00) >> 8
m.PlayMIDINote(DataByte3, 127)
End Function
if i leave it like this it plays when i press and when i unpress the MIDI keyboard keys...but if i set it like this:
Function MidiInProc(ByVal MidiInHandle As Int32, ByVal wMsg As Int32, ByVal Instance As Int32, ByVal wParam As Int32, ByVal lParam As Int32) As Integer
TextBox1.Invoke(New DisplayDataDelegate(AddressOf DisplayData), New Object() {wParam})
Dim DataByte3 = (wParam) >> 8
m.PlayMIDINote(DataByte3, 127)
End Function
It only plays when i unpress...
I would like it to play only when i press the MIDI keyboard keys!
Thanks....

Alright 
Please post the contents of your TextBox1 after pressing and releasing a single key.

No - not for a single key but for two different keys please, in sequence.

i am not understanding : ((((
can you set an example?... i guess the textbox1 is not affecting the MIDI playing!!!
What is making the play its the "m.playMIDINote" function!!!
The textbox1 is just for showing the data that is being sent from the MIDI Keyboard into the PC!

OK - try this:
Function MidiInProc(ByVal MidiInHandle As Int32, ByVal wMsg As Int32, ByVal Instance As Int32, ByVal wParam As Int32, ByVal lParam As Int32) As Integer
Dim Status As Byte
Dim Note As Byte
Dim Velocity As Byte
TextBox1.Invoke(New DisplayDataDelegate(AddressOf DisplayData), New Object() {wParam})
Status = (wParam And &HFF)
If Status = 90 Then
Note = (wParam And &HFF00) >> 8
Velocity = (wParam And &HFF0000) >> 16
m.PlayMIDINote(Note, Velocity)
End If
End Function

You need to go into more detail with problem descriptions. "Not working" is not helping me understand. Does it not do anything any more or still the same problem as before or what?

if i set it like this:
If Status <> 90 Then
it seems to work...the 90/80 might not be the "correct" value!

I missed that you formatted the output as hexadecimal. Change that line to:
If Status = 144 Then

i am encountering this issue..i do not know where to put the
Dim duration = CInt(cboduration.Text)
m.NoteDuration = duration
code.... i tried several ways, but when i load the app, it doesnt updades..only after a manual update it plays ok! Basically when i load the app..the duration is infinite!!

It looks like something gets stuck..i overpassed the problem by adding this:
m.PlayMIDINote(0, 0)
m.STOPMIDINote(0)
to the form´s load event!!
