The control usually displays common properties or functions in the smart volume label, providing users with easier and faster settings, such as the intelligent gridview. To create a smart volume label for a control, you need to implement the actionlist of the control to be added to the project to be displayed in the smart volume label. This article takes the tdat
Article 5: Learn about the historical reasons behind the _ com_ptr_t Design_ Com_ptr_t is a proprietary template class of Microsoft in VC. It encapsulates the QueryInterface (), AddRef (), and Release () operations of IUnknown, and provides some member functions to operate COM interface pointers. At the same time, _ com_ptr_t also simplifies the operations of the COM interface on reference count and query operations between different interfaces.

Some time ago, when I checked for Control Memory leakage, I finally found an error: When I used xmldom (COM), the dispatch pointer (release) was not released because I used an interface pointer repeatedly ), as a result, memory leakage occurs, and such errors (such as BSTR type leaks), the VC debugger and bondcheck are powerless. The solution seems to be only carefu
the globalization has been running for many years in a stable. Bitcoin transactions between any two accounts are faithfully recorded on a large number of redundant ledgers.
In a bitcoin network, any account is anonymous, and any transactions between accounts are non-tamper-proof and are recorded on each node. Then through to the mining of bitcoin incentive mechanism to achieve the self-operation of this network, without any centralized trading system.

Vswitches play an obvious role in networking. As the exchange industry continues to develop, many new types of switches have emerged. Smart switches are one of them, when smart switches gradually move towards the edge of the network, they are always faced with various questions from users: whether smart switches are used to make minor use of the edge, whether the

In the article, we mentioned that this program has memory leakage (the manifestation is that the Destructor is not called), and three solutions are provided at that time:
Allocate the label object to the stack instead of heap.
Set tag space QT: wa_deleteonclose for label
Call Delete to delete the label object allocated to heap through new.

Java card is an intelligent card that can run Java program. For this new Java platform, sun's branch oft developed the Java card 2.0 API technical specifications. As a result, some authorized parties are implementing this API on the smart card. Java cards to be compiled and 2.0 concurrently should be in the procedural order. Developers must understand the internal meanings of Java cards from the physical structure, that is, the internal core class, an

smart pointer (smart pointer) is a class that stores pointers to dynamically allocated (heap) objects and is used for lifetime control to ensure that dynamically allocated objects are destroyed automatically and correctly to prevent memory leaks. One of its common implementation techniques is the use of reference counts (reference count). The smart pointer class

The introduction to DesignerActionList and DesignerAction on MSDN is: The DesignerAction feature allows components and controls to display case-sensitive information and commands. The DesignerAction feature can be treated as a substitute for a designer verb because designeractionitem can appear in the smart tag panel or in a shortcut menu associated with a component or control. For developers who want to add smart

The Chinese often say that "the fish and the bear's paw cannot have both sides", while the English often says that "XX is a double-edged sword ". In essence, this reflects world conflicts, and we must make trade-offs. However, I prefer the Chinese saying that it has a feeling of thinking carefully and thinking twice before a conflict occurs. When you realize that
