The simple approach is to copy the required code into the new system by adding the relevant files to the existing system and paying special attention to the following issues
1\ if a menu or other resource is used in the original design, the corresponding resource should be added manually in the new menu. There are no other good ways to find out.
2\ If some resource names are duplicated, you need a small amount of source code to modify
3\ You can add #include "resource.h" to a source file for a new resource file that is not recognized
4\ for the new system, you need to add the source code corresponding to the header file
5\ in the new system, add a Custom controls control and set the class name of the control to the name of the class specified in the source file
6\ in the new system, add a variable for the Custom control controls. If not added, the program may not run
