Clearing an edit field (numeric) and text area

Hey guys,

Just a quick question about how to clear a numeric edit field. Ive tried using the following code to clear both a numeric edit feild and text area. This code doesnt work as an error pops up saying the 'Value' must be double scalar

Thanks :)

A numeric edit field cannot be blank. You can read more about the value properties of this component here.

MATLAB rejects the value if:

• The value is NaN, blank, or a complex number.

Sorry, should have been more clear, I would just like to reset the value in the box to zero and the value in the text area to be 'Reset button has been pushed'

[Cris LaPierre]

Yes, and currently you are trying to set it to be blank, hence the error message. You must set the Value to a number. Try changing it to this

app.InputvalueEditField.Value = 0;

[William Corluka]

Perfect, I did try that beforehand but with the 0 inbetween the ' ' marks, and it seemed to reject the whole button press.

Thanks again Cris!

Ah, putting it in quotes makes it text, resulting in the error message you were seeing.
