I think it would make more sense to pass the width and height as separate paramaters.

Also, as mentioned last time, please add a space after the comma.  There are more of these below as well, I won't point them all out.

More spaces needed after commas throughout this function.

This size is possibly going to be too small if the string is translated to a longer one - 256 would be a good choice.  Also, let's use `WCHAR` rather than `wchar_t`.

Again, add space after commas (more of which below which I won't point out).

> Use `ARRAY_SIZE(statusTxt)` instead of hardcoding the size here.  Add spaces either side of the '+'s (and after the commas).

I think that the final arg would be clearer if written as `(currentCol - lineIndex) + 1` (basically compute the column index as zero-based first of all, then add the one to make it ones-based).

You shouldn't need the ampersand in front of `EDIT_CallBackProc` - the identifier on its own refers to the function's address.

Note that after this second commit, the executable fails to start on Windows.  That's something which we'd want to fix.
