如何使用WIN32进行文件复制保护 [英] How to make a file Copy Protect using WIN32

问题描述

你好..

我已经使用Core WIN32&创建了一个文件.代码是这样的:

Hello..

I have created a file using Core WIN32 & code is like this :

HANDLE hFile = CreateFile("E:\\FileName123.txt", GENERIC_READ,0,0,OPEN_ALWAYS, FILE_ATTRIBUTE_READONLY, 0);

这将在E:Drive中创建一个名为FileName123的文件.

我的问题是:当它将在E:Drive中创建文件时，它必须变为Copy Protect.也就是说，文件不应复制到其他位置.

请问您对此有何建议..

谢谢..

This will create a file with name FileName123 in E:Drive.

My question is: When it will create the file in E:Drive, it must become Copy Protect. That is., File should not copy to other location.

Please can u suggest any solution for this ..

Thanks..

推荐答案

一个简单的解决方案是以独占模式打开文件，即CFile :: shareExclusive.

a simple solution is to open file with exclusive mode, ie CFile::shareExclusive.

您已将"0"列为第三位参数(dwShareMode)到CreateFile()并以独占模式打开文件.

因此，在关闭句柄之前，无法再次打开文件.

You have passed ''0'' as third parameter (dwShareMode) to CreateFile() and the file is opened in exclusive mode.

Therefore, the file can''t be opened again until the handle is closed.
