Description |
This
form of OBJ( ) function returns a string
containing information about a given custom control
object (i.e., BUTTON, LIST_BOX,
etc.). If the control doesn't exist, ProvideX returns an
Error #65: Window element does not exist or already
exists. The example below shows what is returned for
existing LIST_BOX 10. The string returned by the OBJ(
) function contains 64 characters:
0020 LIST_BOX
10,@(10,10,60,10),FMT="L8 B2 L20 C10 N15
C3"
