The first step: to first determine the source file encoding format:
Storing the file in the given character set can potentially store encoded information in the first three bytes of the file, so the basic principle is to read out the first three
Concurrency and data reading
When multiple sessions simultaneously access (manipulate) the same data, there are some unexpected results, including:
– Dirty Read--Dirty reads
-Non-repeatable-non-repeatable reads
-Phantom read-Phantom reads

When writing a program, we often needWchar_t *GoChar *, Or fromChar *GoWchar_t *Here I will summarize several methods:
1. SlaveWchar_t *GoChar *
wchar_t nameW[256] = L"Hello, World";charname[256] = {0};size_tsizeConverted =
1. open the file:Extern file * fopen (_ const char * _ restrict _ filename, _ const * _ restrict _ modes); if the execution is successful, the pointer to the file to be opened is returned. If the execution fails, null is returned.
2. close the file:

First, we introduce a symbol: g_c_d is the abbreviation of greatest common divisor (maximum common divisor). g_c_d (x, y) indicates the maximum common divisor of X and Y. Then we need to know that all the dikes of an odd number are odd. This is very

If you write a program in the Unicode environment today and convert the cstring to the const char * type, an error is returned: "cannot convert parameter 1 from 'wchar _ T * 'to 'const char *'". After a long search, we finally found three solutions:
, ebp ebx = Name pointers tableDec ECxMoV ESI, [EBX + ECx * 4]Add ESI and ebp esi point to name pointerYou can search for it by yourself!
TIPS:1. It is best to add wairforsingleobject when writing network shellcode again.2. Do not forget exitprocess to avoid many program errors.3. Do not have 0a after the code passes xor99, because in IE overflow, 0a is converted to 0d0a, which will be shortened during string copy.Let's write this! I hope you will be inspired!
