Zebra 扫描器 SDK 事件

Question

我正在尝试使用 Zebra 扫描仪型号：DS3608 拍照并将其保存到我的电脑中。 我不想为此使用 Scanner 123，而只是我的程序。

我正在尝试为此使用图像事件： 图片事件 当成像扫描仪以图像模式捕获图像时触发。要接收 ImageEvents，应用程序需要使用 SUBSCRIBE_IMAGE 事件类型执行 REGISTER_FOR_EVENTS 方法。

这是我的测试代码。文本框 1 有效，似乎我可以拍照，但我的程序从未进入 ImageEvent（至少看起来是这样，文本框 2 保持不变。）

using CoreScanner;
namespace WinFormsApp1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        // Declare CoreScannerClass
        static CCoreScanner cCoreScannerClass;
        private void button1_Click(object sender, EventArgs e)
        {
            textBox1.Text = "Button clicked";
            //Instantiate CoreScanner Class
            cCoreScannerClass = new CCoreScanner();
            //Call Open API
            short[] scannerTypes = new short[1]; // Scanner Types you are interested in
            scannerTypes[0] = 1; // 1 for all scanner types
            short numberOfScannerTypes = 1; // Size of the scannerTypes array
            int status; // Extended API return code
            cCoreScannerClass.Open(0, scannerTypes, numberOfScannerTypes, out status);
            int imageMode = 3000;
            int registerEvents = 1001;
            string outXML; // Output
            string inXML = "<inArgs>" +
            "<scannerID>1</scannerID>" +
            "</inArgs>";
            string inXML2 = "<inArgs>" +
                "<cmdArgs>" +
                    "<arg-int>1<arg-int>" +
                    "<arg-int>2<arg-int>" +
                "</cmdArgs>" +
            "</inArgs>";
            cCoreScannerClass.ExecCommand(imageMode, ref inXML, out outXML, out status);
            cCoreScannerClass.ExecCommand(registerEvents, ref inXML2, out outXML, out status);
        }
        void OnImageEvent(short eventType, int size, short imageFormat, ref object sfimageData, ref string pScannerData)
        {
            textBox2.Text = "Image Event";
        }

        private void textBox1_TextChanged(object sender, EventArgs e)
        {

        }

        private void textBox2_TextChanged(object sender, EventArgs e)
        {

        }
    }
}```
