Description: 打开一个TXT文件并显示在EDIT控件中
步骤:
1.新建一个基于对话框的工程，名称为ReadFile
2.在界面上添加一个按钮(IDC_BUTTON1)和一个文本编辑(IDC_EDIT1)
IDC_EDIT1的属性:多行、可下拉滚动条.
3.编辑按钮触发事件(void CReadFileDlg::OnButton1())
void CReadFileDlg::OnButton1()
{
// TODO: Add your control notification handler code here
CString sFileFilter=\"*.hex|*.hex\"
CString sFileName
CFileDialog fDlg(true,NULL,NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,sFileFilter,NULL)
fDlg.DoModal()
sFileName=fDlg.GetFileName()
if(sFileName!=\"\")
{
CFile file(sFileName,CFile::modeRead)
int nFileLength=file.GetLength()
char *buffer
HGLOBAL hgl=::GlobalAlloc(GMEM_MOVEABLE,nFileLength+1)
buffer=(char *)::GlobalLock(hgl)
file.Read(buffer,nFileLength)
SetDlgItemText(IDC_EDIT1,buffer)
::GlobalUnlock(hgl)
::GlobalFree(hgl)
}
UpdateData(false)

Description: 从串口读取数据，有两种方法，1、每接收一个EV_RXCHAR,就用ReadFile读一次，这样我觉得太恐怖了。2、接收到一个EV_RXCHAR后，等一定数据量的CPU周期(GetTickCount),再一次性读取缓冲区里的数据。这样做，一般情况下不会有问题，但是，如果数据很多，过了“一定数据量的CPU周期”，还没收完数据怎么办？就会少读数据了。 我用三个线程序来完成串口数据的接收，其实就是第一种方法的变种： 一个侦听EV_RXCHAR,一个对EV_RXCHAR进行分析，其实就是超时判断。如果接收到一个消息后，一段时间没收到下一个EV_RXCHAR，就认为是一个数据包的结束。这个线程就会通知数据接收线程，进行数据接收。一般同一包数据，两个字符之间的时间间隔，应该很小了吧，而两个数据包之间的间隔，应该不会太小吧！（这个地方我不清楚，猜的:( :) ）最后一个线程，是接收数据的。-read data from the serial port, there are two methods, one, each receiving a EV_RXCHAR, on the ReadFile read, I think this vote. 2, received a EV_RXCHAR after a certain volume of data, such as CPU cycles (GetTickCount), and the one-time reader, the data buffer. To do so, under normal circumstances there is no problem, but if many of the data, and after a "certain amount of data the CPU cycles," also confiscated End Data how do? Few will read the data. I used three lines to complete serial data reception, the first method is a variant : an interception EV_RXCHAR, one pair of EV_RXCHAR analysis is, in fact, overtime judgment. If a receiver to the news, some time had not received a EV_RXCHAR, it is a data packet to an end. This thread will receive notification of data threads for da

Description: 命名管道充分利用了Windows NT和Windows 2000内建的安全机制。
将命名管道作为一种网络编程方案时，它实际上建立了一个客户机／服务器通信体系，并在其中可靠地传输数据。
命名管道是围绕Windows文件系统设计的一种机制，采用“命名管道文件系统(Named Pipe File System，NPFS)”接口，因此，客户机和服务器可利用标准的Win32文件系统函数(例如：ReadFile和WriteFile)来进行数据的收发。
-named pipe full advantage of the Windows NT and Windows 2000 built-in security system system. To be named as a pipeline network programming package, which is actually the establishment of a client/server communication system, and in which reliable data transmission. A named pipe is on the Windows file system design of a mechanism, "Named Pipe File System (Named Pipe File System, NPFS) "interface, therefore, client and server can use standard Win32 file system functions (such as : ReadFile and WriteFile) data to the transceiver.
