Write Ors ("title") ">" ors2 ("name ")" Q uot; ORS. movenext () Wend It is slower than the following code: Strsql = "select

Use reserve to avoid unnecessary Memory Allocation When you know exactly or approximately how many elements will eventually appear in the container vector int V; // if you do not need to use reserve to allocate memory first, the following cycle will re-allocate the memory multiple times (involving expensive actions such as allocation, recycling, copying, and destructor) v. reserve ( 1000 ); for ( int I = 1 ; I 1000 ; ++

for such class encapsulation. Because it is a read-only attribute, rather than a read/write attribute, we may not consider the issue. Welcome to the fantastic "reference"-based type system! In such a system, any member that returns the reference type will return a handle of the object ). This handle allows the caller to reach the internal data structure of the object, and the reference contained in it can be changed without using the object. Obviously, we want to

C language implementation interface (do not use MFC \ To avoid forgetting), mfc I feel that MFC is not a programmer's detail, and the basic interface is implemented today to avoid forgetting it later.

Recommendation 111: Avoid bidirectional couplingBidirectional coupling refers to the mutual reference between two types. The following code is a typical bidirectional coupling: class A { private b b; Public void MethodA () { b.methodb (); } } class B { private a A; Public void MethodB () { A.methoda (); } }Two-way coupling under the same project, the

Recommendation 70: Avoid logging exceptions where the call stack is lowerNot all exceptions are recorded to the log, in which case the scenario where the exception occurred needs to be recorded, and the other is the uncaught exception.

His insurance agency would only repay him, however, a amount depending on the size of the largest "lake" on his farm.The farm is represented as a rectangular grid with N (1≤ n ≤100) rows and m (1≤ m ≤ ) columns. Each cell in the grid is either dry or submerged, and exactly K (1≤ k ≤ N x M

height by following the height of the floating element. The problem is that floating elements are outside the scope of the parent element's package, and if followed by text, or floating elements, the layout will be confusing.So we finally have to clear the floating element code in each column, so that the entire parent element can properly wrap its inner floating elements, avoid these naughty float elements around.The simplest way to clear floats is

concept: the "avoid double negation" in this article refers to the modification of the double negative statements in the code into simple affirmative statements, so that the code can be read and the maintenance is convenient.text: Avoiding double negation refactoring itself is very easy to implement, but we have seen it in too many code because double negation reduces the readability of the code so that it is very easy to misunderstand the true intent
