版本 - Ver ​

函数简介 ​

返回当前插件版本号。

接口名称 ​

Ver

DLL调用 ​

long Ver(long ola);

参数说明 ​

参数名类型说明
ola长整数型OLAPlug对象的指针，由 CreateCOLAPlugInterFace 接口生成。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
string val = ola.Ver();
csharp
using OLAPlug;

var ola = new OLAPlugServer();
string val = ola.Ver();
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
val = ola.Ver()
java
import com.olaplug.OLAPlugServer;

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

OLAPlugServer ola;
string val = ola.Ver();

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
long valPtr = Ver(instance);
if (valPtr != 0) {
    char val[512] = {0};
    GetStringFromPtr(valPtr, val, sizeof(val));
    FreeStringPtr(valPtr);
}
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();

long instance = CreateCOLAPlugInterFace();
long valPtr = Ver(instance);
if (valPtr != 0) {
    StringBuilder val = new StringBuilder(GetStringSize(valPtr) + 1);
    GetStringFromPtr(valPtr, val, val.Capacity);
    FreeStringPtr(valPtr);
    string valStr = val.ToString();
}
python
from ctypes import CDLL, c_int, c_int64, create_string_buffer

ola = CDLL("OLAPlug_x64.dll")
ola.CreateCOLAPlugInterFace.restype = c_int64
instance = ola.CreateCOLAPlugInterFace()
valPtr = Ver(instance)
if valPtr:
    buf = create_string_buffer(512)
    ola.GetStringFromPtr(valPtr, buf, 512)
    ola.FreeStringPtr(valPtr)
    val = buf.value.decode("utf-8")

返回值 ​

字符串：当前插件的版本描述字符串。

注意事项 ​

  • DLL调用返回字符串指针地址，需要调用 FreeStringPtr 接口释放内存。
