Don't read it!
I am an initiator of SDK, and I am ready to learn VC. I have experienced the pain of beginners of SDK. Many books on the book are some slightly complex programs. Therefore, I will debug some of the small programs, functionality, and attach the details of the procedure to help me.
/ Below is the program
/ * ------------------------------------------ This program is mainly practiced how to achieve Button Displays the effect of various button controls, the name on the control is the set style of the button.
