C++ 将控制台数据输出到另一程序并执行

Question

请问如何将每次鼠标点击的坐标输出到另一个程序的输入框中
现在写的代码使用点击的鼠标坐标输出到cmd中，想将每一次点击的输出到网络调试助手并执行，请问该怎么实现，尝试了一下postmessage但是没有成功。

if (!capture.isOpened()) { //test cam
    cout << "cam open error" << endl;
    return 0;
}

        cout << "frame is empty" << endl;
        break;
    }

    //first frame
    if (frameNum == 1) {
        result = Movedetect(frame, frame);
    }

    else {

    if (waitKey(20) == 27) {
        cout << "Quit" << endl;
        break;
    }
    temp = frame.clone();
    frameNum++;
}

}

Mat Analysismovement::Movedetect(Mat temp, Mat frame) {
Mat result = frame.clone();

//1.covert the cam to gray
Mat gray1, gray2;
cvtColor(temp, gray1, COLOR_BGR2GRAY);
cvtColor(frame, gray2, COLOR_BGR2GRAY);

//2.subtract 2 frame
Mat diff;
absdiff(gray1, gray2, diff);
//imshow("sub", diff);

//3.color
Mat diff_thresh;
threshold(diff, diff_thresh,50,255,THRESH_BINARY);
//imshow("color", diff_thresh);

//4.kernel transfer
Mat kernel_ercode = getStructuringElement(MORPH_RECT, Size(3, 3));
Mat kernel_dilate = getStructuringElement(MORPH_RECT, Size(18, 18));

//5. Corrosion transformation
erode(diff_thresh, diff_thresh, kernel_ercode);

//6.Dilate transformation
dilate(diff_thresh, diff_thresh, kernel_dilate);

//7.search and draw outline
vector<vector<Point>>contours;
findContours(diff_thresh, contours, RETR_EXTERNAL, CHAIN_APPROX_NONE);
drawContours(result, contours, -1, Scalar(0, 0, 255), 2);

//8.outline
vector<Rect>boundRect(contours.size());
for (int i = 0; i < contours.size(); i++) {
    boundRect[i] = boundingRect(contours[i]);
    rectangle(result, boundRect[i], Scalar(0, 255, 0), 2);
}
return result;

}

使用socket通讯吧，你的程序（udp 客户端）通过socket，将鼠标坐标参数发送给NetAssist（udp 服务端）。
