CUSTOM Control

[jacky Wang]

I try to build a cutom control, which simluates the action of a switch. This control shows like a real relay, see below. And I'm referring the examples in "C:\Program Files\National Instruments\CVI71\toolslib\custctrl". Unfortunately, no whole projects that I could refer is under that foder. So I post here and ask from help:1, a whole project example;2, Instruction/Manul on how to build a custom control. Besides, in order for better describing my question, I attached a screenshot here. Thanks a lot Jacky / ____/ ____ open relay ___________ shut relay

You might be able to achieve what you want by using a Picture Ring control. For example, you could generate two bitmaps (using Paint, or whatever) which showed the two different graphic states of your 'switch', attach them to the Ring control then use the control's callback to display one or the other, depending on your program.

Thanks!
Then is there any project/example that I can refer to create a cutom control by writing codes like under "C:\Program Files\National Instruments\CVI71\toolslib\custctrl"?

Thanks

The attached project shows what I was trying to describe earlier. It might prompt a few ideas of your own. I apologise in advance for the pitiful graphics - art was never my strong point.
