What you are doing should work and always works for other people.
I made some minor changes to the code above (for example: use UInt32
here instead of long int), especially since you have a long unsigned
value not a long int anyway.
And you should ALWAYS put in code to trap unexpected but possible
errors such as the resource not being found and not being able to lock it.
So the strong suspicion is the problem is your resource!
