图像分类工具ImageClassification1:实现正常、异常、撤销和显示图片功能
图像分类工具其他功能见：图像分类工具
文章涉及到StringAbout::开头的函数具体实现参考：string与Cstring字符串类型转换和其他操作总结
CProcessFile::开头的函数实现参考：文件读写操作工具类CProcessFile
MCountFile函数参考：MCountFile类，统计指定文件夹下包含某个字段文件数目

代码实现
1.选择路径对话框
【选择】按钮实现方法：
void CStartDialog::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
TCHAR szFolderPath[MAX_PATH] = {0};
CString strFolderPath = TEXT("");
BROWSEINFO sInfo;
::ZeroMemory(&sInfo, sizeof(BROWSEINFO));
sInfo.pidlRoot = 0;
sInfo.lpszTitle = _T("请选择待分类图片位置");
sInfo.ulFlags = BIF_RETURNONLYFSDIRS|BIF_EDITBOX|BIF_DONTGOBELOWDOMAIN;
sInfo.lpfn = NULL;
// 显示文件夹选择对话框
LPITEMIDLIST lpidlBrowse = ::SHBrowseForFolder(&sInfo);
if (lpidlBrowse != NULL)
{
// 取得文件夹名
if (::SHGetPathFromIDList(lpidlBrowse,szFolderPath))
{
strFolderPath = szFolderPath;
}
}
if(lpidlBrowse != NULL)
{
::CoTaskMemFree(lpidlBrowse);
}
m_OriginalImgPath=strFolderPath;
GetDlgItem(IDC_EDIT_ORIGIN)->SetWindowTextW(m_OriginalImgPath);
}2.图像显示并分类对话框
【正常】按钮双击事件响应方法
void CImgClassificationDlg::OnBnClickedButton1()
{
CString filePath=StringAbout::IsWithLastDiagonalbar(m_classifyPath)+"正常";
CString myPath=L"normal";
CString pngPath=StringAbout::IsWithLastDiagonalbar(m_classifyPath)+myPath;
SaveDataAndShowNext(filePath,pngPath,myPath);
}【异常】按钮双击事件响应函数同【正常】大同小异，只是文件路径改为“异常”或“abnor”。
StringAbout：：开头的函数参看：
【撤销】按钮双击事件函数实现：
void CImgClassificationDlg::OnBnClickedButton3()
{
// TODO: Add your control notification handler code here
if (m_vImgInfos.size()>0)
{
ImgInfo imgInfo=m_vImgInfos[m_vImgInfos.size()-1];
m_vImgInfos.pop_back();
//显示上一张OCT图片
m_num=imgInfo.img_num;
ShowOCTPng();
//删除分类路径中的文件
DeleteFile(imgInfo.m_octfilePath);
DeleteFile(imgInfo.m_octImgPath);
}
}对话框中用到的变量定义：
CString m_origPath;
CString m_classifyPath;
vector m_vSrcImgPath;
CMyImgShow m_ImgShow;

int** m_ppImgData;
int m_num;
int m_iImgDataW;
int m_iImgDataH;
string m_curImgPath;
vector m_vImgInfos; SaveDataAndShowNext(）函数实现代码：
