Problem report: SHRINKER.ERR, fix to DEVICE_Open/CreateFileA?

[Robert Baruch]

Well, I made the modification to the source code. This time the program 
got past opening the file after it was written to. The program then 
deleted the file, and then tried to do a DeviceIoControl on it:

This last error means "Invalid Parameter".

So I take back my thought that \\.\filename.ext should just open the 
file as a regular file. I think it should be opening the file as a VxD, 
installing it if it isn't already installed. How that's supposed to work 
is beyond me, but I'll see if I can learn about how it should be done.
