Playing a sound and dealing with a keystroke

[thenath24]

Hello all,

I'm currently writing a 3D Game demo and i'm having trouble getting the program to play a sound and deal with a keystroke at the same time.

If a sound is playing the program will wait for the sound to finish before dealing with a user input, this is obviously no good if I want music playing through out i've tried finding examples of how to do this but have had no luck, can anyone help???

Thanks in advance

Use multithreading. Your sound should be on a worker thread allowing the mainline to conunue while the sound is playing.

Hi there,

Thanks for the tip, having read into multithreading on the MSDN library I tried to implement a simple example given in my program.

While it didn't give me any errors, it also didn't work, have I missed something?;

//code that I want to generate a sound
case VK_SPACE:
					unsigned long iID;
					hThread = CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)PlaySound,NULL,0,&iID);
					CloseHandle(hThread);
				break;

//function I want to be called when the new thread is created
void PlaySound(long lParam)
{
	PlaySound("GUN01.WAV",NULL,SND_NODEFAULT);
}

The function argument in CreateThread for the address of your PlaySound function has to be a ThreadProc (you might look that up).

A ThreadProc can be any function that has this form:
[code=c]
DWORD WINAPI ThreadProc(LPVO ID);
[/code]

So, you have to write a funtion like:
[code=c]
DWORD WINAPI theNath24(LPVOI D arg)
{
//use arg to point to a struct whose member contain
//the arguments for PlaySound()
//Fish out the arguments.
//You call PlaySound() here
}
[/code]

Then you make your CreateThread call:
[code=c]
struct Parms
{
//Put your arguments in here as members
};
Parms* args = new Parms;
//Load args members with the values for PlaySound()
//
hThread = CreateThread(NU LL,0, theNath,args,0, &iID);
//
//off you go.
[/code]
