关于WinCC上位 实现声音报警功能

#include "apdefap.h"

int gscAction( void )
{
// WINCC:TAGNAME_SECTION_START
// syntax: #define TagNameInAction "DMTagName"
// next TagID : 1
// WINCC:TAGNAME_SECTION_END

// WINCC:PICNAME_SECTION_START
// syntax: #define PicNameInAction "PictureName"
// next PicID : 1
// WINCC:PICNAME_SECTION_END
#pragma code("winmm.dll")
BOOL   PlaySound(LPCTSTR lpszSound,HMODULE hmodule,DWORD dwsound );
#define SND_FILENAME 0x00020000L
#define SND_ASYNC 0x0001

#pragma code( )
BOOL bret = FALSE;
if(GetTagBit("test")==1); //返回类型:BOOL
 bret=PlaySound("D:\1.WAV",NULL,SND_FILENAME|SND_ASYNC );
return 0;
}
