Then, since you are using a CString, you can write

There is no need to put 177 anywhere. If you feel compelled to do this, =

#define CHAR_PLUS_MINUS 177

One way to discover this is to do

I am using MSVC 7.1.3088 on MS XP 5.1 service pack 2.
I am trying to write the plaus or misu sign to a display window using
CDC:TextOut. I can write the symbol to a character buffer using
sprintf(csText, "%s (%c%f %s)", csLabel, 177, fError, csUnits);
which gives me
"Elevation (=B17.926902 Meters)" in csText.
However, when I try to write it to the window using
TextOut(DeviceContext, (int)(pWindowPoint.x), (int)(pWindowPoint.y),
I get a rectangle where the =B1 (plus or minus) sign should be.
Is there a way I can write the PM sign to the window? I would like my
text to run vertically.
Many thanks in advance,

Many thanks for your help and sorry for my tardy reply. I guess this
necessitates MFC. I have been trying to do this inside a class that
is called by my MFC-using code but does not actually use MFC.
