The variables in the program follow the Hungarian notation, "prefix + variable meaning", the meaning of the variable is one or more English words, the first letter of each word capitalized, do not use Hanyu Pinyin instead. The variable prefix is three lowercase letters indicating its type, and the prefix you need to add follows Microsoft's recommendati

Because of the development of information big data, all walks of life unavoidably with the information discipline to have the intersection, my study specialized for surveying and mapping engineering, the surveying and mapping profession also has many people to develop a lot of useful measurement software. So from the perspective of students, how we look at the application of these software, here on my own point of view, there may be a lot of immature places, welcome everyone to criticize.I'd lik

Each system defines a message with a unique identifier and a constant to declare the meaning of the message. For example, wm_paint requires the window to draw its content.
The symbol constant specifies the type of the system-defined message, and the prefix of the constant specifies the type of the form for processing the interpreted message. The following table lists the message categories associated with the prefix.
