I have never created an FLL, but this code was in a previous message here in the UT, for create an FLL to detect idle item. I have attempted to compile in in MSVS c++ 6.0. But I get 7 errors and 1 warning. I'm hoping someone with real knowledge (I don't have it) of C++ could compile this into an FLL for me.

Thanks in advance. The code is in the first block, followed by the errors I received in the second block:
