in my dialogBox window, I have three buttons with name labeling A,B, and C. For example if a user clicks on button A, then that button A change its label to lower case "a" with color highlighted on the button. So i wonder what function should I use to change text labeling and add color highlight on the button? I'm not using MFC and I'm new to WinAPI as well so thank in advance.
In Win32 you should be going for custom paint of the button and then when the click happens you change the variable of the background color of the button.
