basics global variables

Posted on by testaccPA 104

Hello, a beginner question, but I want to learn the behavior:

I declared a global text variable on onStart and bound it to the text of a label.

Now I want to manipulate the value with a button and let it show immediately in the label.

How do I do that?

Kind regards

    In the OnSelect property of the button add the same formula you used in the OnStart property, but change the value.  If you set the text property of the label to the name of the variable you should see the new value as soon as you press the button.

    For example, let's say you used this code in the OnStart property

     

    Set(myVar,"hello world")

     

    Put this code in the Text property of a label.

     

    myVar

     

    And finally, create a button and put this ocde in the OnSelect property

     

    Set(myVar,"goodbye world")

     

    Click the button.  The label will now read "goodbye world"
