Before I actually try this, I thought I''d ask here. I am writing a level editor for my game now, and am about to do the file IO functions. I usually use the stdio.h (FILE*) family of functions, but I heard once before somewhere that MFC blocks all disk file functions except for it''s own CFile stuff. Is this true? ------------------------------ Jonathan Little invader@hushmail.com http://www.crosswinds.net/~uselessknowledge

No,

You can read/write however you want. As a default MFC uses it serialise function to read write the document data, but in my one and only MFC proggie I had to read/write a text file. Just override the open/close file functions and write your own data access stuff. (this was using vc5 not 6).
