Everyone should know that the read configuration file can use the system API getPrivateProfileString () (the prototype is as follows), I originally packaged it into a class, but when I was used today (I didn't have an error before.) I tried a few times or there was no effect, and I wrote one of myself.
DWORD GETPRIVATEPROFILESTRING (LPCTSTSTR LPAPPNAME, LPCTSTR LPKEYNAME, LPCTSTSTR LPDEFAULT, LPTSTSTSTSTSTSTSTSTSTSTER LPRETURNEDSTRING, DWORD NSIZE, LPCTSTSTR LPFILENAME)
Oh, boring people. The factors considered are:
1. Some people like to write Key = Value, and some people like Key = Value, and the intermediate space must be handled.
2. In some configuration files, each section plus an empty line, this is not considered.
3. In order to increase the speed, I reduced the number of read files. I originally thought that when I read a key, the record keys and their key values, but the test results show that it is better to read the fast (sacrifice space To achieve performance - a very routine practice)
The code is posted below, the test passes:
