Is that
Value = 1111
or is it
Value = '1111'
If it is numeric, then how do you want to process negative numbers, and how do you want to process numbers with fractional part, and how do you want to process numbers that would typically be expressed in scientific notation?

value='1111'
out=numel(value)

If your Value is numeric type, then:
out = floor(log10(Value)+1);
if Value is char type then:
out = numel(Value - '0');

That does not work.
The characters are not explicitly defined as elements in an array, but rather string values in a handle.
elCount = str2num('Value') = []

Edit boxes do not have a Value. Edit boxes have a String.
S = get(handles.edit1, 'String');
length(S)
