Debug Project (String scroll bar)

Recommended Posts

Howdy!

I am currently working on a simple Debug message system project. Its 2 VI's, one is the console and other is a wrapper for a queue. The console waits for elements in the queue and displays them in the string control on the front panel; and the wrapper is just a VI that obtains, en-queues the message, and releases the queue reference.

My question is I would like the string control to read top to bottom in the order the messages are received and programmaticly(sp) "scroll" to bottom when needed. What I can't find is a way to scroll. I can set if the vertical scroll bar is visible but can seem to find a way to change the scroll position.

I know I could flip everything upside down and have the last message received be the top message, but what would be the fun in that. (It's be like giving up).

Additionally, I would like to have the Send Debug Message.vi check if the Debug console is running and if not; run it. I can get a list of all VI's in memory but I'm not sure how to get a reference to a specific VI. (meaning I'm not sure how to get the full path of a VI in memory) I remember reading about someone having an Abort all Running VIs but can't find it. I would think that would have my answer.

I have attached what I currently have.

Thanks for your help

Hi Ryan

Use the Text - Scroll Position property node to move the scroll position.

In order to get a reference to a VI in memory...

The other way would be to check for an error returned from the Open VI Reference function if the VI is not in memory. It's up to you.

Thanks,

I figured was a property node for setting the scroll position, I was simply looking in the wrong spot. :frusty:

I didn't realize that the Open VI Reference would except the VI's name. Guess it would help to read the help files sometimes.
