How might I implement a rotary encoder knob?

Hi all,

I am currently using the 6.0 version, is there a work-around to use mouse-wheel-scrolls?

Hello TurboMetrologist,

I am not sure if there is a workaround for CVI 6 since this is no longer support and the UIR changed formats in CVI 7.1. You can take a look at the code and try and implement it in CVI 6 by creating a new UIR, though some commands may not be available in CVI 6 that are used in a later version. Have a great day!

Best Regards,

Turbo:

CVI 6.0 doesn't have built-in support for the mouse wheel, but you can use InstallWinMsgCallback () to capture Windows message WM_MOUSEWHEEL.

Look at the attached sample (developed in CVI 6.0), which just has a numeric dial which can be controlled by the mouse wheel.

This sample is based on several I found on the forum and on the toolbox sample that shipped with CVI 6.0, ..\CVI\samples\toolbox\msgdemo.prj

Thanks! That was an excellent example.
