How build buttons that can be excuted once when mouse down, but recover to its original status when mouse up

[zhiheng]

Basically, I want to build several independent buttions. When one button gets the mouse down event, some code is excuted once, but when mouse up, the button go to its original status, and wait for the next click.,

this should be pretty simple in other languages (C++, or Java), anyway, I feel so hard to figure it out in Labview.

Any help will be greatly apprecitated!

Right click on the button and select Mechanical Action>Latch When Released and make sure you place the terminal for the button inside the event. A value change event is all that you need for this.

thanks Dennis
I find the part:"Mechanical Action>Latch When Released", but I have no idea what's "make sure you place the terminal for the button inside the event"
I am totally a rookies, can you make it clearer? If possible, it will be great if there is a sample.
thanks again

A latch action means, a button will stay in its position [action] until it is read by the code.

This means to connect the button to a true case or simply place the button inside the Value Change event of the Event Structure [ES].

Put the Execution Highlighting mode & run the code, you ll see what we mean.
