Intrinsic Controls in Visual basic
The visual basic 6.0 provides some standard controls on its control box which are known as intrinsic control. These are built-in controls and are contained in Visual basic .EXE file. These are different from the extrinsic controls (ActiveX objects and Insertable objects) in the sense that they always reside in the control toolbox, while the others are required to be inserted through the components.
Name, Caption (or text in case of textbox), font, are common properties of all controls which are related to the controls basic properties.
How to use the properties within a particular control:
Syantax: Controlname.property=value
Ex:- txtcountry.text=”India” here the txtcountry is a text box assigned a value of “India” to its property text.
How to use the properties within a particular control:
Syantax: Controlname.method(parameters)
Ex:- lstname.additem(“my name”) the method additem is here adding a new item in the listbox.
The codes using these properties and/or methods are generally written either within a function, procedure or an event-procedure while writing a VB 6.0 programs.
