生成GUID - GenerateGuid ​

函数简介 ​

生成全局唯一标识符（GUID）。

接口名称 ​

GenerateGuid

DLL调用 ​

c
long GenerateGuid(long instance, int type);

参数说明 ​

参数名类型说明
instance长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。
type整数型类型：0-带-的GUID如{123e4567-e89b-12d3-a456-426614174000}；1-不带-的GUID如123e4567e89b12d3a456426614174000。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
string guid = ola.GenerateGuid(0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
string guid = ola.GenerateGuid(0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
guid = ola.GenerateGuid(0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
String guid = ola.GenerateGuid(0);
cpp
var ola = com("OlaPlug.OlaSoft")
var guid = ola.GenerateGuid(0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
guid = ola.GenerateGuid(0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
guid ＝ ola.GenerateGuid(0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var guid = ola.GenerateGuid(0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
文本型 guid = ola.GenerateGuid(0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
std::string guid = ola.GenerateGuid(0);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
long ptr = GenerateGuid(instance, 0);
if (ptr != 0) {
    char buffer[4096] = {0};
    GetStringFromPtr(ptr, buffer, sizeof(buffer));
    FreeStringPtr(ptr);
}
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringFromPtr(long ptr, StringBuilder lpString, int size);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int FreeStringPtr(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern int GetStringSize(long ptr);
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long GenerateGuid(long ola, int type);

long instance = CreateCOLAPlugInterFace();
long ptr = GenerateGuid(instance, 0);
if (ptr != 0) {
    StringBuilder sb = new StringBuilder(GetStringSize(ptr) + 1);
    GetStringFromPtr(ptr, sb, sb.Capacity);
    FreeStringPtr(ptr);
    string guid = sb.ToString();
}
python
from ctypes import CDLL, c_int, c_int64

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
ptr = ola.GenerateGuid(instance, 0)

返回值 ​

返回值说明
非 0成功，返回 GUID字符串的指针。
0失败。
