IcmpSendEcho GPF on W7

[oxidadus]

Hi there,

Im having strange issues with ICMP Module linking, i declared types for icmp module and made it work fine in windows xp, but gives me a GPF on windows 7 and 10. Im developing in Clarion 9.1, can anyone help me with this? Im trying to use IcmpSendEcho to know if one pc is online on my LAN or not to transfer files.

My declaration

MODULE('icmp')
IcmpCreateFile(),UNSIGNED,PASCAL,RAW,NAME('IcmpCreateFile')
IcmpCloseHandle(UNSIGNED),UNSIGNED,PASCAL,RAW,NAME('IcmpCloseHandle')
IcmpSendEcho(LONG,LONG,STRING,LONG,LONG,*ICMP_ECHO_REPLY,LONG,LONG),LONG,PASCAL,RAW
END

Best regards
