How to change Context Help at Runtime ?

[Munna232]

Hello All,

I need small information. Please help me.

Is there is any way to change the context help at Runtime?

Actually I want to display Context Help based on OS Language.

Hi Munna,

you can change the tip strip with a property node, but you can't change the context help for a control.

I tend to use a different scheme:

Detect mouse enter/leave events for each control of interest. Display a text based on the reference of the control under the mouse in a string indicator. Now you can change the displayed strings depending on language settings…

Hi GerdW,

Thanks for your Idea. It’s working nice.

Actually it’s quite uneasy if no of Indicators/controllers are more.

If NI will provide property node for Context Help  then it’s more useful.

Hi Munna,

what's uneasy?

You can get all control references at once using a property of the VI/panel. Then you just select/filter text by control name…

Hi GerdW,

Thanks for your help.

I can read all control values at once but I’m not getting how to display Help window for that particular control (By Event).

Like this I can get, But as I told in my previous post, Event cases will increase based on No. of controller/indicators (please correct me if I’m wrong).

And other issue, at Runtime we can change context help window size/position but what about Help Text indicator (which we are talking)?

May be we can do workaround like, displaying another VI (looks like context Help window) & sync up with Event/custom menu.

Hi Munna,

- you can create user events for your controls, so the event structure reduces to just one ( or two) event cases for that help.

- you can create a case structure with a case for each control outputting the help text for that control. (Or use a lookup table approach.)

- you can create an additional window using a subVI. You can make user interfaces with autoscaling options in LabVIEW to mimic that help window.

You can do all this. You have to program it using opportunities found in LabVIEW…
