String manipulation is one of the most common and basic operations in programming. As a VC programmer, both novice or master have used CString. And it seems that it's hard to get away with it in real programming (although it's not a library in standard C + +). Because this class that is provided by MFC is too convenient for us to manipulate strings, CString not only provides a variety of operational functio

When you use a char array, you will find that the length of the elements of the char array is fixed. That is, once the array has been created, it is immutable. If we want to make the size of the array elements can be changed, then in MFC use CString array, if it is a pure C + + environment, the use of string array, are able to reach the demand.

I. Definition
CString is a very useful type of data. They largely simplify many of the operations in MFC, making it much easier for MFC to do string manipulation. In any case, there are a lot of special techniques for using CString, especially for programmers who come out of the pure C background.

These days I have studied VC and made it a multi-threaded server. I suffered repeated setbacks on the cstring and learned some articles from the experts on the Internet (in fact, it was well written by msdn, but it was hard to understand English.In fact, the most important thing is that cstring is a class and a reference. Some operations can direct

On MSDN, CString can be used to arbitrarily replace function parameters of the const char* and LPCTSTR type. Just change it at random. Do not delve into, solve the problem first.Declare the purpose of use: Pass the CString type string value to the new thread, but the AfxBeginThread function needs to pass in the LPVoid type parameter. So, the contradiction began.S
Convert CString type to int type
The simplest way to convert data of the CString type to an integer type is to use a standard string to an Integer Conversion routine.
Although you usually suspect that using the _ atoi () function is a good choice, it is rarely the right choice. If you want to use Unicode characters, you should use _ ttoi (), which is compiled into _ atoi () in the ANSI coding system (), in

I read a lot of programs written by myself, including some code, and found that a large part of the bug is about the incorrect usage of CString In the MFC class. the main cause of this error is that you do not know much about the CString implementation mechanism.
