}<br />

<br />
In the above example, if I define 'secret' as char* secret, and then use new and delete to allocate a buffer for it I get an acess violation.  When I use GlobalAlloc as shown, it works.  The help files say to use the heap function instead of GlobalAlloc, but I've never used them.<br />
<br />
I'm clearly missing the big picture on memory allocation for dlls.  Brain talks about four different dll memory models, but I'm not grocking the concept.<br />
