用Ｃ实现的统计一个目录下的所有源程序共有多少行

/*
Original code by : Mihai Filimon
Modifications by S. Sridhar 
1. Added a edit control where the user can type in the path
2. If the path typed in the edit ctrl does not exist then the 
   user will be propmted as to whether he/she wants the path 
   to be created
3. Setting the flag bShowFilesInDir to TRUE will result in all 
   the files in the current folder to be displayed in the dialog
4. If u don't want to display all the files then u can use the 
   file filter to display the file types u want to display
5. Calling API SetTitle with the desired title will set the Title 
   of the dialog. This API has to be invoked before DoModal is called
6. User can pass the Initial Folder to be displayed in the constructor 
   of CSelectFolder
