使用MATLAB从另一个应用程序中的控件获取文本

str然后将包含所需的String.优质教育基金

MATLAB的External Functions接口允许以各种语言调用函数,其中包括Java.如本回答所述,与Windows API交互的流行Java库是Java Native Access(JNA).

在这个答案中演示了如何利用JNA发送WM_GETTEXT消息.针对此问题的特定需求进行了调整并转换为static方法,所需的Java-JNA代码如下所示:

package hack.graphic.devil

import com.sun.jna.Native;
import com.sun.jna.Pointer;
import com.sun.jna.platform.win32.WinDef.HWND;
import com.sun.jna.platform.win32.WinDef.LRESULT;
import com.sun.jna.win32.StdCallLibrary;

public class User32Util {
    interface User32 extends StdCallLibrary {
        User32 INSTANCE = (User32) Native.loadLibrary("user32", User32.class);
        int WM_GETTEXT = 0x000D;

        LRESULT SendMessageA(HWND editHwnd, int wmGettext, long l, byte[] lParamStr);
    }

    public static String getStringFromHexHWND(String args0) {
        User32 user32 = User32.INSTANCE;
        HWND target = new HWND(new Pointer(Long.decode(args0)));
        byte[] lParamStr = new byte[512];
        user32.SendMessageA(target, User32.WM_GETTEXT, 512, lParamStr);
        return Native.toString(lParamStr);
    }
}

javaaddpath(fullfile(pwd,'User32Util.jar'));
...
str = char(hack.graphic.devil.User32Util.getStringFromHexHWND(['0x' dec2hex(hTmp(5))]));
