Scrolling down String programatically

[Ranjeet_Singh]

I have a string which is updating continously in the fixed interwal. After each interval it will be updated with some new charchers.

Now I want to string scroll down programmatically when new data arrives. But it is not scrolling down.

I tried to simulate same with VI I attched.

You have to program that. Use the Text.ScrollPos property to set the position of the scroll bar.

Thanks. I found that already. Along with this string length is what I need.

String length isn't needed.  If you always want to do is scroll to the bottom use the Inf constant.

But can be done using string length. I think using strlen is better then infinite constant?

[RavensFan]

Why do you think that would be better?

[Ranjeet_Singh]

I think becasue instead of using infinite, using some fixed and valid value is better.

Depends what you want.  If you are always going to the end, using INF is by far the simplest, and according the NI, the best way to do it.  There's no need for you to calculate the string length and do weird math that may or may not be quite right.  Keep It Simple Stupid (KISS).

[Ranjeet_Singh]

Calculating string length points always to the right place and it is working reliably. 

It will be great help to provide some link stating INF is better and why?

But I agree INF is better then STRLEN because it doesn't need calculate the strlen in each loop iteration

Thanks for the concern

Did you read the thread that Hooovahh left earlier?  It is Darren, from NI R&D telling us to use it.
