Re: HKLM\Init and MFC Application (further clarification)

Paul,

The application is certainly not read-only on my PC in the flat release
directory. When I use "My Device" on the emulator, however, the properties
show it as read only. Also, I am given an error message when I try to remove
that property. This doesn't really surprise me though, since the emulator is
treating this as though it were flash, correct? Isn't that what XIP means?
That it doesn't need to load it into ram, but just executes it "in-place?"
