Not withstanding compiler options to include Direct X which I will leave to the person attempting to make sense out of Microsoft's programming~!

Also the Resource file programming and using key accelerators and or mouse actions or cursors or anything else used in a program.

 

Still some corrections to the program need to be applied - just a basic 2 window fullscreen program. It works but still some corrections are needed.

 

After some more mickey-mousing with the program (image below)
