There are three types of Controls:1Standard Controls Control 3Insertable objects. The controls that can be used directly in the toolbox are called standard controls, also known as internal controls, and they are included in the visual

Property" is visual

basic objects, which can be modified directly through the attribute table or assigned directly to variables by way of assignment.

An "event" is an action that is pre-set by the system and can be recognized by an object; For example: click on the form, double-click on the form, and so on.

msdn You can first look at the directory to figure out which are the properties and methods of the VB language itself, which are the properties and usage of the controls, and what types of controls are included with VB.

The VB language itself is learned first, and the controls can be learned when they are used.

I often write a little ** by myself to learn.

I think. When you need to use a certain control, you will understand it in detail and remember it most. But you need to have a general idea of what event method properties some of the common controls have.

There is no more detailed information than a book, and I am self-taught, although I cannot say that I am proficient. But it can be done through more practice!

Such as click, double-click, enter, mouse off, open, close, etc. are what you call (event-driven) events.

Event process) is the ** that is executed after these actions are executed

It should be the :name attribute, which is also the name attribute.

Used at the module level to declare common variables and allocate storage space.

private：

dim: declares a variable and allocates storage space.

Go and see the msdn of vb6, which has a detailed description.

Their properties, methods, and events are so numerous that it is impossible to describe and compare them here.
