visible window from system function

[extrnh]

i have a c++ program compiled in visual c++ that links to a c
library. when a system function is called in the c library a blank
command window is displayed while the c logic is executing. this is
from the windows cmd.exe that is executed by the system function. i
need to prevent the window from being displayed and would prefer doing
so from the c++ code (may not get access to c library source). any
suggestions? yes, i'm a newbie.

Ask on a windows programming group.

That's the console window, you're building a console app. YOu need to
build a win app and never create/show the window. How to do that
you'll learn in a windows programming group or searching google. Good
luck.

my apologies for not explaining the problem correctly. the visual c++
part is an mfc automation dll. it is executed by a vba macro in
excel. i have a posting on a windows programming group, no reponses
to date.
