文件共享(不) [英] File Sharing (not)

问题描述

我有一个程序同时在多台PC上运行(VS6.0，C ++，MFC).客户数据文件集中存储在网络上.他抱怨说相同的数据文件可以同时在不同的计算机上打开，而对一个文件所做的更改被另一个文件覆盖.

检查两台PC是否正在访问同一文件是我的问题吗?

如果是我的问题，是否可以通过编程方式检测文件是否已打开

谢谢

I have a program running on several PCs at the same time (VS6.0, C++, MFC). The customers data files are stored centrally on the network. He''s complaining that the same data file can be open on different computers at the same time and changes made to one are being overwritten by the other.

Is it my problem to check if two PCs are accessing the same file or is it an IT function?

If it is my problem is there anyway to detect programatically whether a file is already open somewhere else?

Thanks

以独占方式打开它.所有其他尝试将失败.

Open it exclusively. All other attempts will fail.
