Previously asked on edx code (edx Google Group) How to expand a field for course, such as adding a category field to a course.The reply says to add the field you want directly to the couesefields. Position common/lib/xmodule/course_module.py after. The field is automatically displayed in the Advanced settings. In this way I find that the field is indeed a property of course (experiment in the shell). Howeve

converted to the address of the method to be called and the list of its parameters (stored inTvarrec array), how to pass parameters when calling it. Some preparations are required: 1. First, let's take a look at the passed parameter table: Params. Its type is called Variable-enable by Delphi.Put an array (variant open array), equivalent to array of tvarrec, that is, Params isArray of tvarrec members. In other words, all types of parameters areDelphi is automatically converted to tvarrec (see

state transition. on each platform, there is a specific directive that converts the execution of a process from user state to a core state, which is called the Operating system trap (operating system traps). After the process has been executed into the command, it can run the system call code in the kernel mentality. In Linux it is through soft interrupts to achieve this, on the x86 platform, this instruction is int 0x80. That is, in Linux, the interface of the system call is a special case o

EAX, the parameter is EBX, ECX, edx, EDI, ESI to pass. Writing Shellcode To write Shellcode under Linux, you can use GCC to assemble directly. s file to compile the link, generate the standard executable Elf file, but also can be directly tested, but it is not convenient to extract machine code is very inconvenient.In order to facilitate the extraction of machine code, using the NASM compiler to generate the bin file, no other format data, convenient

8. Offset is the number of immediately. For example, [EBP + EDX * 8 + 200] is a valid address expression. Of course, in most cases, it is not necessary to have such a complex relationship as inter-address, proportional factor, or offset. The basic unit of memory is byte ). Each byte has eight binary bits. Therefore, the maximum number of characters that each word can save is 11111111, that is, 255 in decimal format. In general, it is more convenient

can express all ASCII codes. That is to say, a memory unit can store an English character or number, while a Chinese character must be represented by a unicode code. That is to say, two memory units can hold a Chinese character. It is not hard to understand that the sixteen bits are two bytes. Of course, if there are sixteen bits, there must be thirty-two bits, sixty-fourteen bits, and so on. The thirty-two bits are called dual characters, and the sixty-fourteen bits are called four characters.

command is executed, the configured values are specified through the edX and eax registers, the high 32 bits of the specified value of edX, and the low 32 bits of the value specified by eax, when the preceding registers are set, edX is 0. MSR registers are filled with the specified MSR registers through the ECX registers. The registers of sysenter_cs_msr, sysent
