接口名称

GetPointWindow

DLL调用

long GetPointWindow(long ola, int x, int y);

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。

y整数型屏幕Y坐标。

示例

SDK 调用

cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.GetPointWindow(100, 200);
csharp
using OLAPlug;

var ola = new OLAPlugServer();
long handle = ola.GetPointWindow(100, 200);
python
from OLAPlugServer import OLAPlugServer

ola = OLAPlugServer()
handle = ola.GetPointWindow(100, 200)
java
import com.olaplug.OLAPlugServer;

OLAPlugServer ola = new OLAPlugServer();
long handle = ola.GetPointWindow(100, 200);
cpp
var ola = com("OlaPlug.OlaSoft")
var handle = ola.GetPointWindow(100, 200)
vbscript
Set ola = CreateObject("OlaPlug.OlaSoft")
handle = ola.GetPointWindow(100, 200)
text
.局部变量 ola, OLAPlug
ola.创建 ()
handle = ola.GetPointWindow(100, 200)
aardio
import OLAPlugServer;
var ola = OLAPlugServer();
var handle = ola.GetPointWindow(100, 200);
text
变量 ola <类型 = OLAPlugServer>
ola = 新建 OLAPlugServer
长整数 handle = ola.GetPointWindow(100, 200)
cpp
#include "OLAPlugServer.h"

OLAPlugServer ola;
long handle = ola.GetPointWindow(100, 200);
