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: 字符串操作是一个不小的主题,在标准C++中,string字符串类成为一个标准,之所以抛弃char*的字符串而选用C++标准程序库中的string类，是因为他和前者比较起来，不必担心内存是否足够、字符串长度等等，而且作为一个类出现，他集成的操作函数足以完成我们大多数情况下的需要.
下面我们首先从一些示例开始学习下string类的使用.-i nclude <string>
＃i nclude <iostream>
using namespace std
void main()

Description: str ()的简单实现
strstr(s1,s2)是一个经常用的函数，他的作用就是在字符串s1中寻找字符串s2如果找到了就返回指针，否则返回NULL。-
static const char* _strstr(const char* s1, const char* s2)
{
assert(s2 && s1)
const char* p=s1,*r=s2
while(*p!= \0 )
{
while(*p++==*r++)
if(*r== \0 )
return p
else
{
r=s2
p=++s1
}
}
return NULL
}
