Hello Carlos,

just use the property node "Front Panel Window:Title".
Open a reference to the vi ("current vi's path" -> "open reference") and wire that to a property node. Select property "FP.Title" and wire your string box. That's it (and works also in executables).

Bets regards,

Hi,

In addition, make sure you close the reference! Normally, LV isn't very
picky when it comes to internal references, but when you change a window
title, the new and old reference seems to stay in memory. You will get
memory leaks (until the vi stops, then it is released).

Regards,

Wiebe.

Hello Wiebe,

what do you mean with new and old reference? Does the reference of the vi change, when you change the FP.Title property?
I have a vi, that runs as long as I'm sitting in front of my computer (say 10 hours a day). It sets the title every 90 seconds to signal running processes in Windows taskbar. I close the reference on vi exit and never realize some memory leaks.

Best regards,

GerdW,

If you open a reference, and then, in a loop, change the title, there is no
problem.

But if you open a reference and change the title in a loop, you get problems
when you don't close the reference. This does not happen when you don't use
the Open VI Reference.

The attached VI will hopefully clear things up...

Regards,

Wiebe.
