The ability to create controls is an important addition to Visual Basic’s abilities. Microsoft has put a lot of work into this feature. As a means to code reuse, the abilities of controls are obviously limited to projects that contain forms, but the strength of controls has always been in the user interface.
A lot more could be written about controls—far more than we have space for in this chapter. Do take the time to read the Visual Basic manuals, which go into more depth, and experiment with the samples. After all, writing controls in Visual Basic is certainly much easier than writing them in C++!
