How to prevent copying a file

[nps_ltv]

In an Visual C++ 6.0 application, I need to prevent copying the specified file to other directory, but I don't know how to do. Please help me!!! Thank you very much! P.S. If maybe, you can demonstrate an small application about this. Thank you!

Prevent who ? You could open the file with CFile and use one of the flag to prevent other processed to access it.

You would need to set this restriction at the OS level.

Create a service which opens an exclusive handle to the file. This will prevent copying and deleting.

Using the mfc CFile class CString file_name = _T("C:\\AnotherFile"); CFile f; f.Open( file_name, CFile::modeRead | CFile::shareExclusive ); while(1) Sleep(1000);
