输入以下代码：
2 字节(高位优先)
  1. alloc(TypeName,256)
  2. alloc(ByteSize,4)
  3. alloc(ConvertRoutine,1024)
  4. alloc(ConvertBackRoutine,1024)

  6. TypeName:
  7. db '2 Byte Big Endian',0   //CE不支持中文m


  10. ByteSize:
  11. dd 2

  13. //The convert routine should hold a routine that converts the data to an integer (in eax)
  14. //function declared as: stdcall int ConvertRoutine(unsigned char *input);
  15. //Note: Keep in mind that this routine can be called by multiple threads at the same time.
  16. ConvertRoutine:
  17. //jmp dllname.functionname
  18. [64-bit]
  19. //or manual:
  20. //parameters: (64-bit)
  21. //rcx=address of input
  22. xor eax,eax
  23. mov ax,[rcx] //eax now contains the bytes 'input' pointed to
  24. xchg ah,al //convert to big endian

  26. ret
  27. [/64-bit]

  29. [32-bit]
  30. //jmp dllname.functionname
  31. //or manual:
  32. //parameters: (32-bit)
  33. push ebp
  34. mov ebp,esp
  35. //[ebp+8]=input
  36. //example:
  37. mov eax,[ebp+8] //place the address that contains the bytes into eax
  38. mov ax,[eax] //place the bytes into eax so it's handled as a normal 4 byte value
  39. and eax,ffff //cleanup
  40. xchg ah,al //convert to big endian

  42. pop ebp
  43. ret 4
  44. [/32-bit]

  46. //The convert back routine should hold a routine that converts the given integer back to a row of bytes (e.g when the user wats to write a new value)
  47. //function declared as: stdcall void ConvertBackRoutine(int i, unsigned char *output);
  48. ConvertBackRoutine:
  49. //jmp dllname.functionname
  50. //or manual:
  51. [64-bit]
  52. //parameters: (64-bit)
  53. //ecx=input
  54. //rdx=address of output
  55. //example:
  56. xchg ch,cl //convert the little endian input into a big endian input
  57. mov [rdx],cx //place the integer the 4 bytes pointed to by rdx

  59. ret
  60. [/64-bit]

  62. [32-bit]
  63. //parameters: (32-bit)
  64. push ebp
  65. mov ebp,esp
  66. //[ebp+8]=input
  67. //[ebp+c]=address of output
  68. //example:
  69. push eax
  70. push ebx
  71. mov eax,[ebp+8] //load the value into eax
  72. mov ebx,[ebp+c] //load the address into ebx

  74. //convert the value to big endian
  75. xchg ah,al

  77. mov [ebx],ax //write the value into the address
  78. pop ebx
  79. pop eax

  81. pop ebp
  82. ret 8
  83. [/32-bit]

为什么在CE界面上点击了鼠标右键并没有弹出菜单“定义新的自定义类型（自动汇编）”选项啊？

在数值类型的下拉菜单框上点
