函数简介 ​

读取指定地址的数据，返回数据指针。

接口名称 ​

ReadDataAddrToBin

DLL调用 ​

long ReadDataAddrToBin(long instance, long hwnd, long addr, int len);

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。
hwnd长整数型窗口句柄。
addr长整数型地址。
len整数型长度。

示例 ​

SDK 调用 ​

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.ReadDataAddrToBin(hwnd, 0, 0);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
long handle = ola.ReadDataAddrToBin(hwnd, 0, 0);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
handle = ola.ReadDataAddrToBin(hwnd, 0, 0)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
long handle = ola.ReadDataAddrToBin(hwnd, 0, 0);
cpp
var ola = com("OlaPlug.OlaSoft")
var handle = ola.ReadDataAddrToBin(hwnd, 0, 0)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
handle = ola.ReadDataAddrToBin(hwnd, 0, 0)
text
.局部变量 ola, OLAPlug
ola.创建 ()
handle ＝ ola.ReadDataAddrToBin(hwnd, 0, 0)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var handle = ola.ReadDataAddrToBin(hwnd, 0, 0);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
长整数 handle = ola.ReadDataAddrToBin(hwnd, 0, 0)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.ReadDataAddrToBin(hwnd, 0, 0);

原生 DLL 调用 ​

cpp
long instance = CreateCOLAPlugInterFace();
ReadDataAddrToBin(instance, hwnd, 0, 0);
csharp
using System.Runtime.InteropServices;
using System.Text;

[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long CreateCOLAPlugInterFace();
[DllImport("OLAPlug_x64.dll", CallingConvention = CallingConvention.StdCall)]
static extern long ReadDataAddrToBin(long ola, long hwnd, long addr, int len);

long instance = CreateCOLAPlugInterFace();
ReadDataAddrToBin(instance, hwnd, 0, 0);
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()
ola.ReadDataAddrToBin(instance, hwnd, 0, 0)

返回值 ​

返回值说明
（返回值）读取到的数据指针，返回0表示读取失败。
