Update while typing in numeric control?

Question

So...
When I type a number into a numeric control, it doesn't update until I hit enter or click somewhere outside the control.
Problem is, after entering the number, I want to click on a "go" button
to do something with the new value in numeric control, but unless I
remember to click somewhere else or hit enter first, I'm doing
something with the old value, not the new value.
This gets aggravating.
How to make sure the value of the numeric control gets updated before doing something with it?
"update while typing" exists for string controls, but seems conspicuously lacking for other types of controls...

Answer 1

I cannot reproduce your described behavior: With either a local variable or the numeric control inside the event case, I never see a stale value. Please attach your VI so we can troubleshoot.
Adding a delay to fix something like this is incorrect and dangerous. If a delay solves the problem, it points to a flaw in the code.  What if somebody will run your program on a slower computer where it would suddenly need a 12ms delay. You'd be back to sqaure one, dealing with race conditions.
(And why are you using "mouse down" instead of "value changed"?)
