PE文件和COFF文件格式分析——签名、COFF文件头和可选文件头3
《PE2》中介绍了一些可选文件头中重要的属性，为了全面起见，本文将会讲解那些不是那么重要的属性。虽然不重要，但是还是可以发现很多好玩的情况。首先看一下32位的可选文件头详细定义。（转载请指明来源于breaksoftware的CSDN博客）

Value

0x0001

0x0002

0x0004

IMAGE_DLL_CHARACTERISTICS_DYNAMIC_BASE
0x0040

IMAGE_DLL_CHARACTERISTICS_FORCE_INTEGRITY
0x0080

IMAGE_DLL_CHARACTERISTICS_NX_COMPAT
0x0100

IMAGE_DLLCHARACTERISTICS_ NO_ISOLATION
0x0200
Isolation aware, but do not isolate the image.
IMAGE_DLLCHARACTERISTICS_ NO_SEH
0x0400
Does not use structured exception (SE) handling. No SE handler may be called in this image.
IMAGE_DLLCHARACTERISTICS_ NO_BIND
0x0800

IMAGE_DLLCHARACTERISTICS_ WDM_DRIVER

IMAGE_DLLCHARACTERISTICS_ TERMINAL_SERVER_AWARE

MAGE_DLL_CHARACTERISTICS_DYNAMIC_BASE是说Dll可以在加载时被重定向，我发现我电脑上文件SDKDBLib.dll是特例，它没有设置这个属性，这个文件也没有设置IMAGE_DLLCHARACTERISTICS_ NO_SEH，即该文件不使用SEH。
