pb中使用winapi生成唯一的永不重复字符串(UUID)

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
