Prevent two users from accessing the same file at the same time

[Shawn]

Well, the subject sais it all. What is the best approach to prevent this
from happening?

Thanks,

Hi Shawn,

You can setting a flag in an ApplicationStat e, e.g.
Application["fileAccess ed"]. In Application_Sta rt set it as false,

Application["fileAccess ed"] = false;

Only when it's false to allow to access and shift it to true and also set a
flag in Session. Once finish accessing the file to shift Application flag to
false and delete Session flag. Or in Session_End to check Session flag,
accordingly shift Application flag.
