IDD_DIALOG1  should be a number, defined in your rc file.
Something like
#define   IDD_DIALOG1   5
step01.cpp doesn't know what that value is, so gives the error.

Usual solution is to move all of the resource #defines into a resource
header file (.rh) that you then include in both the .rc and the .cpp

.
