how to handle burns

The So-called handle is actually a data, which is a long (full-length) data. A handle is a unique integer used by wondows to identify objects that are created or used by the application, and Windows uses a variety of handles to identify such as application instances, Windows, controls, bitmaps, GDI objects, and so on. The Windows handle is somewhat like a file

A simple point-coordinate classClass Point {PublicPoint (): Xval (0), Yval (0) {}Point (int x,int y): Xval (x), Yval (y) {}int x () const {return xval;}int y () const {return yval;}point x (int xv) {xval = XV; return *this;}point y (int yv) {yval = YV; return *this;}Privateint Xval, yval;};Bind the handle to it on a layer of encapsulationControlling those operations through handle exposes those operations t

This article said that the original is somewhat far-fetched. As the topic says, more is the summary of the predecessors ' methods. The original intention of writing is not a technical study, but a job demand. Methods involved in some functions need to mention the right, in fact, I always thought that the standard on the Internet to raise the right function is useless, until this writing program I just know that there is a real need to mention the right. Now attach a relatively good-looking right

This article uses WinDbg to understand how functions in a program use handle to query a handle table. So first to open the Win7 under the WinDbg and debugging functions. Solve the kernel debugging problem under Win7 Win7 Debug is not available for kernel debugging by default (! Process and other commands are not available), unless it is a dual-machine debug. or use LIVEKD for debugging. Try th

Handle table with kernel object One, what is a handle table what is a kernel object. 1. Handle Table GenerationWe know. When we use CreateProcess, we return a process handle. and the thread handle. In fact, when calling CreateProcess. A new eprocess structure is created in t

Case analysis of handle leakingIn the previous article. NET object with Windows handle (ii): Handle classification and. NET Handle disclosure example, we have a handle leak example. The Datareceiver and Dataanalyzer objects were created and dispose of in the example many tim

Attach to a console A process can be attached to a console using the attachconsole function, and only one console can be attached to a process. A console can have many processes attached to it. You can call the getconsoleprocesslist function to obtain the list attached to a console. Close a console A process can use the freeconsole function to remove itself from a console. If other processes share this console, the console will not be destroyed, but the process that calls the freeconsole funct

(i) graphical objects and their handles I. Graphical objects Matlab graphic objects include: 1, matlab each of the specific graphics must include computer screen and graphics window two objects Two, the graphic object handle 1. Definition When you create each drawing object, Matlab assigns the object a uniquely determined value, which is referred to as a handle to a drawing object. PS: (1) The computer scr

When developing high-performance network programs. The Windows developers say that Iocp,linux developers will say Epoll. It is clear that Epoll is an IO multiplexing technology that can efficiently handle millions of socket handles, and is much more efficient than the previous select and poll.We used to epoll to feel pretty cool, really fast, then. Why on earth can it handle so many concurrent connections q

Pspcidtable holds all process and thread objects in the system, which are either the process ID (PID) or the thread ID (TID). Let's look at the handle_table structure in WinDbg first:You can see that the content stored in address 0x83f41bc4 is 0x 8da010a8, which is the structure of the system's _handle_table.Well, now WinDbg is getting handle_table structure, or code implementation. Here is a simple plus offset:Eprocess address of the system processPeprocess eprocess = (peprocess) 0x86aee798;#de
