I'm trying to play some music from MIDI events,
and i'm trying to play it with the synchronization in Chapter 8.Becuase I'm trying to make the code as short as possible,so i want to use it with the simplest way.....

I'd try some examples,but they all mixed with MFC,and I'm new to that ...Q_Q

Here is my program...
hMidiOut = OpenMidiOut(NULL,0,hSync,MIDIOUT_DEFAULT);

MidiEvent Evt;
for( i = 0 ; i < 10 ; i++){

Evt.status = 0x90; //noteOn
Evt.data1 = 0x2C + 2*i; // pitch
Evt.data2 = 0x60; //volume
Evt.time = i*40;

PutMidiOut (hMidiOut, &Evt);


I thought these code may make some noise at least,but I got nothing until I misused a NULL pointer,and he made the sound I expected!!!

May someone please tell me how can I make it work correcttly?

P.S. Those code runs under .NET 2003....

Thanks for your help ....

Hi Qshi,
No MFC in your code so you shouldn't have to worry about it. But your OpenMidiOut call should have a window handle as the first parameter. What do you mean by "misued a NULL pointer"? Your code should work fine.

Thanks for your reply ....

I found my code truly work fine....
And the reason I thought it was not...
Just because I heared nothing ...
And after I used a busy loop instead of a windows handler ,to tell when it is finished sending event...

Then I can hear it !! ^^
