picture box. When you load an image into a picture box the picture

does not resize itself by default to fit the image as the image control does but it will if you set its AutoSize property to True.

the picture property and load the image. Private Sub Command1_Click()

DIFFERENCES BETWEEN IMAGE AND PICTURE BOX

CONTROLS

As they change shape, image controls stretch the image they contain. Picture boxes and forms do not.

Image controls are lightweight controls. This means that an image control will consume less memory and is faster to deal with than picture boxes.

CONT’D Graphics methods which allow you to draw graphics

on the fly at run time, can not be used to draw on image controls but they can draw on top of picture box controls.

A picture box’s can be used as container objects. This means other objects can be drawn and grouped inside them.
