这么多语言了，为啥没有AHK的呢，马上就有了下面就有了！

CreateGUID()
{
    VarSetCapacity(pguid, 16, 0)
    if !(DllCall("ole32.dll\CoCreateGuid", "ptr", &pguid)) {
        size := VarSetCapacity(sguid, (38 << !!A_IsUnicode) + 1, 0)
        if (DllCall("ole32.dll\StringFromGUID2", "ptr", &pguid, "ptr", &sguid, "int", size))
            return StrGet(&sguid)
    }
    return ""
}

下面给出使用方法

MsgBox % CreateGUID()    ; ==> {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}

给出GUID比较函数

IsEqualGUID(guid1, guid2)
{
    return DllCall("ole32\IsEqualGUID", "ptr", &guid1, "ptr", &guid2)
}

上述函数的应用示例

GUID_1 := CreateGUID()
GUID_2 := CreateGUID()

MsgBox % IsEqualGUID(GUID_1, GUID_2)    ; ==> 0
MsgBox % IsEqualGUID(GUID_1, GUID_1)    ; ==> 1
