Thank you, That is fantastic and perfect! Just another typist

I've been looking at methods of implementing realtime file monitoring. I have looked at validtec's API hooking SDK, which is not ideal for my purposes. Alfa's File monitor COM component is superb... My question is: Does anybody know of any other alternatives? Just another copy and paste artist

Many thanks! This has pointed me on the right track. I have found similar posts and the answer seems to be afxwin.h. Unfortunately I still can't compile: _DllMain@12 already defined in HookFunc.obj I have found a Microdoft specific knwledge base article describing this problem but that relates to specific modules that there is a problem with. I don't think that's what I'm seeing, more likely I'm just doing something dumb. Just another typist

Any thoughts on the problem below will be a great help: I am trying to use CFile in an MFC app. My thinking is that it should be available with no further includes as stdafx is included which includes windows.h? However vc++ tell me CFile is an undeclared identifier. CFile is declared in afx.h however I can't include afx.h by itself as the compiler complains that windows.h is being redeclared. What am I missing... Just another typist

Anyone know where I can buy a binary file patching component? I am in dire need. Have tested rt-Patch from poscketSoft, but it doesn't seem to handle large files well. I've seen a lot of mention of something called FastBIT, but can't find where to buy it. I'm about to test Alessandro Vergani's solution http://www.codeproject.com/tools/unpatcher.asp , just waiting for the monster 80mb download from MS of the platform sdk. Just another typist
