Help With DllCall...

[Proph]

I am having a hard time understanding how to use dllcalls. I found what looks to be a simple function that would be handy to use... which let's you unlock files if they are in use. The dll's original function is this:

kernel32.dll

BOOL UnlockFile(
  HANDLE hFile,
  DWORD dwFileOffsetLow,
  DWORD dwFileOffsetHigh,
  DWORD nNumberOfBytesToUnlockLow,
  DWORD nNumberOfBytesToUnlockHigh
);

Can someone show me what this would look like in autoit as a function?

Thanks.

UnlockFile does not allow you to unlock files that are in use. It is used in conjunction with LockFile to lock/unlock regions of a file so that you have exclusive access to that region. See here for more information on this API function.

Woops... you are right.

@Kogmedia Yes I know about unlocker. But if I used a third party tool like that in my script it wouldn't be very pretty. I was hoping to find a way in autoit to do it. so that when I delete a directory I can make sure it is 100% deleted by unlocking it.

You can do this in AutoIt. You need to find the process that has the file open and then kill the process to free the file.
