結論
如果要判斷是否主控台或 GUI 應用程式,您必須剖析 [EXEheader。標頭包含名為 '子系統' 的欄位。這個欄位會決定應用程式是在下執行的子系統和它所需要的介面的型別。這些值組成:
   IMAGE_SUBSYSTEM_NATIVE               1   IMAGE_SUBSYSTEM_WINDOWS_GUI          2   IMAGE_SUBSYSTEM_WINDOWS_CUI          3   IMAGE_SUBSYSTEM_OS2_CUI              5   IMAGE_SUBSYSTEM_POSIX_CUI            7   IMAGE_SUBSYSTEM_NATIVE_WINDOWS       8   IMAGE_SUBSYSTEM_WINDOWS_CE_GUI       9
