Custom Controls

[Eric W]

I want to build a custom control that will display a signal indicator.
Basically I have 4 images and depending on the current state, I will display
one of these images on the screen. I want to build it as a custom control
so i can add it to multiple pages of the form.

The control should also allow me to set the state of the control..

Ie. when i set state to 1, image 1 will be displayed and so on.

Please could you advise me on how to do this ?

Many thanks.

Eric,

Personally I would just use a PictureBox control and supply the Image
property at run-time with a given image based on criteria.

But if you want your own custom control, just inherit from PictureBox
and create your own State property.

Check here for details on inheriting from existing controls:
