Hi guys

I'm recoding an app i wrote as i know how to do it more effienctly now and with more options.
But ran into this slight problem maybe you have used this before?

Code Select


;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

    invoke LockFile,      
    hFile,                                      ;file handle
    dwFileOffsetLow,                     ;where the lock should begin
   dwFileOffsetHigh,                      ;where the lock should begin
   nNumberOfBytesToLockLow,      ;length of the byte range to be locked
   nNumberOfBytesToLockHigh       ;length of the byte range to be locked
  
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

Im just locking this file just incase of users trying to edit it read it or write to it etc.
Thanks

You shouldn't need this API unless you want to lock parts of the file. If you want to lock the whole file pass the appropriate flags to CreateFile. :)
