There are many ways to set the VB.NET property, and its application is also very important in practical programming. When the user can set or get the value of the property, these properties are changing. This property can be changed at design time. Users can set the values of these properties in the properties window without writing any code, and some code cannot be changed at design time, so some code that sets the values of these properties must be written in the running program.

Properties that can be set and read at run time are called "read-write" properties. Code that can only be read at run time is called the "read-only" attribute.

The VB.NET property setting is 1. Set property value

When you need to change the appearance or behavior of an object, you can change the property value of the object. For example, you can change the contents of a textbox by changing the value of the Textbox property of the Textbox control.

To set the value of a property, you can use the following syntax

Object.property=expression

Some examples are as follows:

TextBox1.Top=200 'Let the Top attribute value be 200TextBox1.Visible=True' display TextBox TextBox1.Text= "hello" 'display "hello" in TextBox

The VB.NET property setting 2. Get the value of the attribute

When the code wants to do something on an object, the user may need to get the state of an object, for example, when making the next operation on a TextBox control, he may need to know the value of the text property of TextBox, and so on.

Typically, the user can get the property value of an object with the following syntax:

Variable=object.property

Users can treat the property value of an object as part of a complex expression without first assigning the property value to a variable and then evaluating it. The following example is the code that changes the property of a radio button:

Private Sub cmdAdd_Click ()

'[statements]

RadioButton1RadioButton1.

Top=RadioButton1.top+20

'[statements]

End Sub

Note: if the user needs to use a property value multiple times in the VB.NET property setting, assigning the property value to a variable first will make it more efficient.
