判断目录是否存在并创建目录：
// Test Whether the dir exist
CString m_dir;
if (m_dir.Right(1) == “\\”)
m_dir = m_dir.Left(m_dir.GetLength()-1);
if (GetFileAttributes(m_dir) == FILE_ATTRIBUTE_DIRECTORY)
return TURE;
else
CreateAllDirectory(m_dir);
// Function CreateAllDirectory
// recursive function
void CreateAllDirectory(CString Dir)
{
if (Dir.Right(1) == “\\”)
Dir = Dir.Left(Dir.GetLength()-1);
if (GetFileAttributes == FILE_ATTRIBUTE_DIRECTORY)
return;
else if (GetFileAttributes(Dir) != -1)
{
if (DeleteFile(Dir)) // delete the file with the same name
if (CreateDirectory(Dir, NULL))
return;
MessageBox(_T(“Can not create directory for captured pictures”), NULL, MB_OK);
}
int n = Dir.ReverseFind(‘\\’);
CreateAllDirectory(Dir.Left(n));
if (!CreateDirectory(Dir, NULL))
MessageBox(_T(“Can not create directory for captured pictures”), NULL, MB_OK);
}
青年人网站提示判断Dir中某个文件是否存在,还可以通过FileFind来实现:
BOOL FileExist(CString strFileName)
{
CFileFind fFind;
return fFind.FindFile(strFileName);
}
