WinCE自学2周心得体会（WinCE蓝牙连接打印机（打印机PCL语言））
各位大神们，看见小弟写的博客可不要笑话，小弟也是第一次写博客，初来乍到多多指教，本人也是还没毕业的学生，在一家公司进行实习，实习5个月了，公司主要是做管理系统，跟硬件也有一些接触，一个星期以前老板安排让我做一个WinCE的系统，扫描枪用蓝牙连接打印机打印一维码和Vin码，当时一听这个任务就给我吓蒙圈了，还是实习生刚毕业的我来说还是很有难度的，从开始的demo做起，用扫描枪扫描商品码，通过蓝牙连接打印机，控制打印机打印所扫出来的条形码对WinCE一个星期的接触觉得自己对这个东西还是蛮感兴趣，因为个人比较喜欢玩硬件，这个任务刚好有硬件可以玩，下面给大家分享一下这一个星期所遇到的问题。（此文章纯属笔录，大神看见不要喷）
1、第1个问题就是所编写的程序不能正常在WinCE扫描枪上运行，始终报错无法找到Device.dll文件。
解决方案：询问供应商所给的文件有问题。
2、第2个问题无法解决扫描时的声音
解决方案：创建类Sound
public class Sound
{
private byte[] m_soundBytes;
private string m_fileName;
private enum Flags
{
SND_SYNC = 0x0000, /* play synchronously (default) */
SND_ASYNC = 0x0001, /* play asynchronously */
SND_NODEFAULT = 0x0002, /* silence (!default) if sound not found */
SND_MEMORY = 0x0004, /* pszSound points to a memory file */
SND_LOOP = 0x0008, /* loop the sound until next sndPlaySound */
SND_NOSTOP = 0x0010, /* don't stop any currently playing sound */
SND_NOWAIT = 0x00002000, /* don't wait if the driver is busy */
SND_ALIAS = 0x00010000, /* name is a registry alias */
SND_ALIAS_ID = 0x00110000, /* alias is a predefined ID */
SND_FILENAME = 0x00020000, /* name is file name */
SND_RESOURCE = 0x00040004 /* name is resource name or atom */
}
[DllImport("CoreDll.DLL", EntryPoint = "PlaySound", SetLastError = true)]
private extern static int WCE_PlaySound(string szSound, IntPtr hMod, int flags);
[DllImport("CoreDll.DLL", EntryPoint = "PlaySound", SetLastError = true)]
private extern static int WCE_PlaySoundBytes(byte[] szSound, IntPtr hMod, int flags);
///
/// Construct the Sound object to play sound data from the specified file.
///
public Sound(string fileName)
{
m_fileName = fileName;
}
///
/// Construct the Sound object to play sound data from the specified stream.
///
public Sound(Stream stream)
{
// read the data from the stream
m_soundBytes = new byte[stream.Length];
stream.Read(m_soundBytes, 0, (int)stream.Length);
}
///
/// Play the sound
///
public void Play()
{
// if a file name has been registered, call WCE_PlaySound,
// otherwise call WCE_PlaySoundBytes
if (m_fileName != null)
WCE_PlaySound(m_fileName, IntPtr.Zero, (int)(Flags.SND_ASYNC | Flags.SND_FILENAME));
else
WCE_PlaySoundBytes(m_soundBytes, IntPtr.Zero, (int)(Flags.SND_ASYNC | Flags.SND_MEMORY));
}
}
运用方法： //播放声音
Sound sound = new Sound(@"Scan.wav");
sound.Play();
3、蓝牙打印机PCL语言指令集
//打印条码
void Print_Car()
{

MM5 = this.txt_Car5.Text.Trim();
MM6 = this.txt_Car6.Text.Trim();

}
}
else if (i == 5)

}
string Both = CPCLStr + CPCLStr1 + all + TM + CPCLStr4;
byte[] bytes = Encoding.ASCII.GetBytes(Both);
bth.Port.Write(bytes, 0, bytes.Length);
4、穿件日志文件
创建LogerHelper.cs类文件
public static void WriteLog(String log)
{
//在CE中获取程序所在目录
string FileDir = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase) + "\\lg\\";
if (!Directory.Exists(FileDir)) Directory.CreateDirectory(FileDir);
string FileName = FileDir + DateTime.Now.ToString("yyyy-MM-dd") + ".txt";
FileName = FileName.Remove(0, 1);// FileName.Substring(1, FileName.Length);
// MessageBox.Show(FileName);
try
{
using (StreamWriter sw = File.AppendText(FileName))
{
sw.WriteLine(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + " --> " + log);
}
}
catch (Exception ex)
{
MessageBox.Show("写条码配置文件有问题！" + ex.Message, "ScanBarcode");
}
}
