1、定义结构及外部函数

global type uuid from structure
ulong  data1
uint  data2
uint  data3
character  data4[8]
end type

Function ulong UuidCreate(ref uuid lpUUID) LIBRARY "rpcrt4"
Function ulong UuidToString (ref uuid lpUUID, ref long lpUUIDString)  LIBRARY "rpcrt4" Alias for "UuidToStringA"
Function ulong RpcStringFree(long lpUUIDString) LIBRARY "rpcrt4"  Alias for "RpcStringFreeA"


2、函数主体

CONSTANT Long  RPC_S_OK = 0
CONSTANT Long  RPC_S_UUID_LOCAL_ONLY = 1824

Long ll_rtn
uuid u
ll_rtn = uuidcreate(u)  //Create a new UUID
IF ll_rtn = RPC_S_OK OR ll_rtn = RPC_S_UUID_LOCAL_ONLY THEN
    Long ll_pointer
    String ls_uuid
    ll_rtn = UuidToString(u,ll_pointer)
    ls_uuid = Upper(String (ll_pointer,"Address")) //Convert it to a string

    RpcStringFree(ll_pointer)//Remove the string from the memory
    RETURN ls_uuid
ELSE
    RETURN ""
END IF

注：发布时候可能需要rpcrt4.dll


附：另外一种生成guid的方法

oleObject PBObject
string ls_GUID
long ll_result

PBObject = CREATE oleObject

ll_result = PBObject.ConnectToNewObject &
  ("PowerBuilder.Application")
IF ll_result < 0 THEN
messagebox("","连接失败：与PowerBuilder.Application连接出错！")
Destroy PBObject
  return ""
ELSE
  ll_result = PBObject.GenerateGUID(REF ls_GUID)
END IF
Destroy PBObject

return Mid(ls_GUID,2,len(ls_GUID) - 2)
第二种方法在程序发布时候需要在客户端进行配置：

pbapl80.dll
pbaen80.tlb
rpcrt4.dll

修改注册表如下
