Unlocking a file

[CoolFire]

Hello

I have searched high and low for the answer to my question. I expect that it is right under my nose but it has come time for me to ask anyway. Is there a way to force access to a file on a computer that has been locked by a VB.NET program that is running on another computer

I have a multiuser environment where common data files are stored on a shared server and each program is run separately from each machine. The actual situation is where one system locks a file on the server and for some reason I want to manually release all locks on the files that that system has but from a different computer. I know that I cannot simply use a handle because the second system does not have that handle in memory. I am coding in VB.NET and have checked out the FileStream class as well as others and cannot find anything that will force access into a file

Any help would be greatly appreciated
Thank You

It's not easy to do this. You need to muck around with privileges and such.

I found a sample, but it's in C++:

Maybe you can port it to managed code.
