#!N #!Rdxgecv DXGetEnumeratedComponentValue #!N #!N Function #!N #!N Provides access
to the components of a Field by index rather than by
name. #!N #!N Syntax #!N #!F-adobe-times-bold-r-normal--18* #include <dx/dx.h> Object DXGetEnumeratedComponentValue(Field f,
int n, char **name) #!EF #!N #!N Functional Details #!N #!N
Provides access to all components of the Field #!F-adobe-times-bold-r-normal--18* f #!EF
without requiring a list of component names. We might, for example,
find all components that are dependent on positions by using #!F-adobe-times-bold-r-normal--18*
DXGetEnumeratedComponentValue #!EF in a looping construct in which #!F-adobe-times-bold-r-normal--18* DXGetEnumeratedComponentAttribute #!EF
(or, using the name returned by #!F-adobe-times-bold-r-normal--18* DXGetEnumeratedComponentValue #!EF , using
#!F-adobe-times-bold-r-normal--18* DXGetComponentAttribute #!EF ) is used to access the "dep" attribute
of each component. #!N #!N The components of Field #!F-adobe-times-bold-r-normal--18* f
#!EF may be indexed by calling #!F-adobe-times-bold-r-normal--18* DXGetEnumeratedComponentValue #!EF with successive
values of #!F-adobe-times-bold-r-normal--18* n #!EF until #!F-adobe-times-bold-r-normal--18* NULL #!EF is returned.
The name of the component is returned in #!F-adobe-times-bold-r-normal--18* *name #!EF
. #!N Note: #!F-adobe-times-bold-r-normal--18* DXGetEnumeratedComponentAttribute #!EF would not be suitable for
use in the looping construct because it will return #!F-adobe-times-bold-r-normal--18* NULL
#!EF if the #!F-adobe-times-bold-r-normal--18* n #!EF th component doesn't have the
specified component, even if there are more than #!F-adobe-times-bold-r-normal--18* n #!EF
components. #!N #!N #!N Return Value #!N #!N Returns the value
of the component or returns #!F-adobe-times-bold-r-normal--18* NULL #!EF but does not
set an error code if #!F-adobe-times-bold-r-normal--18* n #!EF is out of
range. #!N #!N See Also #!N #!N #!F-adobe-times-bold-r-normal--18* #!Ldxgca,dxall1227 h DXGetComponentAttribute #!EL , #!Ldxgcv,dxall1228 h DXGetComponentValue #!EL
