VB basics-Controls

VB has two types of controls: standard controls and ActiveX controls.

 

Standard Control: the control that comes with the toolbox

Graphical controls: Image boxes and image boxes

Image boxes cannot be used as parent controls, and text cannot be accepted using the print method

Images can be loaded in both the design and execution phases. The image at the design stage has been added to the executable file, and loadpicture needs to be read from the outside during the runtime.

 

 

For a form, the form can accept focus only when no control on the form accepts focus.

Focus can be set only when the form and control are visible (after show)
