Cipherlab CPT9300手持扫描枪开发体验

设备：Cipherlab CPT9300

OS  ：WinCE 6 R2

主要功能：一维、二维条码扫描。

用途：    大型仓库收发货识别扫描。

资源：   厂家有SDK提供，.net可外部调用的3个Dll及pdf开发手册(英文)。

开发：  vs2008 + .Net CF 3.5

调试：  直接连接设备，未使用仿真机。

2、激光扫描相关编码（Reader）

using System;
 using System.Linq;
 using System.Collections.Generic;
 using System.ComponentModel;
 using System.Data;
 using System.Drawing;
 using System.Text;
 using System.Windows.Forms;
 using Microsoft.WindowsCE.Forms;
 using System.Runtime.InteropServices;
 using Cipherlab.SystemAPI;
 
 namespace CF35_9300Demo
 {
     public struct SystemTime
     {
         public short wYear;
         public short wMonth;
         public short wDayOfWeek;
         public short wDay;
         public short wHour;
         public short wMinute;
         public short wSecond;
         public short wMilliseconds;
     }
 
     public class MsgForm : MessageWindow
     {
         public UInt32 decodeMsg = 0;
         int b1 = 0;
         byte[] lpbuf = new byte[25];
         string tmp;
 
         public Form msgform;
 
         public MsgForm(Form msgFrm)
         {
             msgform = msgFrm;
             decodeMsg = Win32API.RegisterWindowMessage("WM_DECODEDATA");        
         }
 
         protected override void WndProc(ref Message m)
         {
             if (m.Msg == decodeMsg)
             {
                 if (m.WParam.ToInt32().Equals(7))
                 {
                     b1 = Reader.ReaderEngineAPI.GetDecodeData(ref tmp);
                     msgform.Text = tmp;
                 }
             }
             base.WndProc(ref m);
         }
 
     }
 
     /// <summary>
     /// Win32API,WinCE自带
     /// </summary>
     public class Win32API
     {       
         [DllImport("coredll.dll", SetLastError = true)]
         public static extern uint RegisterWindowMessage(string lpString);
 
         [DllImport("coredll.dll", SetLastError = true)]
         public static extern int SetLocalTime(ref SystemTime lpSystemTime);
     }
 }

SDK接口方式是使用Window Message方式，程序和接口(DLL)进行通信，程序先注册自定义消息"WM_DECODEDATA"，然后按键进行扫描Dll扫描到条码后同过WM_DECODEDATA消息发送扫描到的条码给程序，程序窗口重写WndProc方法进行拦截，调用"Reader.ReaderEngineAPI.GetDecodeData(ref tmp);"获取Dll返回的条码字符串。

结论：

1、该设备有点贵哦，上万的售价啊。

2、开发比较简单有CF3.5和厂家提供的SDK开发包的支持像我等小白也可以开发。
