Function prototype: LONG GetWindowLong (hwnd hwnd,int nIndex) Parameter: hwnd: Specifies the handle of the window NIndex: The type value of the information that needs to be obtained NIndex value is as follows: Gwl_exstyl E gets the extended window

The source code (true form) is a binary fixed-point representation of a number in a computer. The original code notation adds a sign bit (that is, the highest bit to the sign bit) before the value: a positive number is 0, a negative number is 1 (0

Debug: A (assembly) Directly merge the 8086/8087/8088 Memory code into the memory. This command creates executable machine codes from assembly language statements. All values are in hexadecimal format and must be entered by one to four characters.

I have encountered big-end and small-end problems in data storage. My sister was confused and found that my basic knowledge was seriously lacking, first, let's take a look at how many bytes each data type occupies on your own machine, and the size

About SUID, SGID, SBITWhen talking about Operation permissions in linux, three permissions (r, w, and x) are assigned to the corresponding three roles (owner, group member, and others, is 3*3 = 9. The records are recorded with 9 flag positions

The original design of Windows allowed us to work with very large files, so the original designer chose a 64-bit value to represent the file size. However, we generally do not exceed 4GB file size during daily processing. Therefore, Windows provides

Character encodingDo you think "ASCII = one character is 8 bits"? Do you think a byte is a character, and a character is 8 bits? Do you still think you still think that UTF-8 is using 8 bits to represent a character? If you really think so, read

[ keywords ] TCP IP Packet architecture specifically interprets network protocolsIn general, network programming we just need to call some packaged functions or components to complete most of the work, but in some special cases, we need to

Binary negative Number:The original code is the original representation methodAnti-code is the inverse of the sign bit (highest bit)Complement = anti-code +1 1 bytes It can only represent 256 numbers anyway, because there is a sign, so we're going

In a multithreaded environment, access to shared variables can be implemented using the lock free technology based on compare and swap, the benefit of which is high efficiency.An extract of atomic operation1.1 AndroidSource:

The base sorting method is also called bucket sort or bin sort. As the name suggests, it distributes the elements to be sorted to some "buckets" based on some key-value information, base sorting is a stable sorting. the time complexity is O (nlog (r)

======================= About symbol extension ============================1. extend short data type to long data type 1. The short data type to be extended is signed Symbol extension, that is, the short data type symbol bit is filled to the long

Source code, anti-code, complement code, personal understanding, anti-Code complement Original code: Binary Fixed-point notation, that is, the highest bit is the symbol bit, "0" indicates a positive number, "1" indicates a negative number, and the

The Aero diagnostics and Repair tool in Windows 7 can easily identify and resolve problems with transparency and other visual effects. But if this tool is not available in some cases, the tips to force the Aero effect in Vista are still valid under

This is the past DOS era of the compilation of source code, although has passed, but for the study of the assembly is still helpful, assembly language is just a basic programmer language, most people can grasp, not necessarily in-depth research.
