Why won't WAV play?

[C.M. Rouleau]

I saw something like this posted and incorporated it into some code as shown. Why won't the wave play?

sound.rc contains only these lines:

welcome wave pc_hall.wav
bye wave pc_hall.wav

sound.rc was compiled with rc and pbres succesfully

the code:

#COMPILE EXE
#INCLUDE "WIN32API.INC"
#INCLUDE "COMDLG32.INC"
'this resource contains the wav files
$RESOURCE "sound.pbr"

FUNCTION PBMAIN ()

LOCAL lpWav AS BYTE PTR

hInst&=GetModuleHandle("")
hRes&=FindResource(hInst&,"welcome","wave")

IF hRes& THEN
lpWav = LockResource (LoadResource (hInst&, hRes&))
IF lpWav THEN FUNCTION = PlaySound(BYVAL lpWav, hInst&, %SND_MEMORY OR %SND_ASYNC)
END IF

DIALOG NEW 0,"Sound Demo",,,200,100,0,0 TO hDlg&

DIALOG SHOW MODAL hDlg&

END FUNCTION
