Ughhh okay a little further info here, it looks like if I try to change
directories (in either dialog) the system will crash with the same error...
this is leading me to believe that the problem isn't actually with the the
"open" or "save" dialog not working properly, but is related to the fact
that I have MANY other timer threads going which are constantly opening and
writing to files (and I never used IMPLICIT paths for any of them)....so I
guess the "default path" is being changed when I tell the "open" or "save"
dialog to change directories (or at least this is the only thing I can think
of that might do it).
Now, having (hopefully) deduced that, can anyone tell me:
A) Does OFN_NOTESTFILECREATE change the default file path (at least
temporarily) which would mean I actually might be right in what I think is
wrong :)
and
B) What is the safest way to have multiple file opening and closing on the
system???? By that I simply mean how can I enforce the default file location
to not change, even if my FileDialogs change the directory (is this even
possible??? or is it perhaps simpler to put a IMPLICIT path to every file
I/O that I have in the code (and yeh there are a LOT of them LoL).
Thanks again for any advice or input :)
BTW - what I mean by IMPLICIT (I'm sure most of yeh know but I might even
have the wrong word there)...instead of:
HBITMAP cBmp = (HBITMAP)::LoadImage(NULL, _T("blank.bmp"), IMAGE_BITMAP, 0,
0, LR_CREATEDIBSECTION | LR_LOADFROMFILE);
use
HBITMAP cBmp = (HBITMAP)::LoadImage(NULL, _T("c:/folder1/blank.bmp"),
IMAGE_BITMAP, 0, 0, LR_CREATEDIBSECTION | LR_LOADFROMFILE);
