Receiving Data from GUI edit box

I am having issues with retrieving the information that the user inputs into the GUI. The edit box is as follows.

IP_Adress_Phone=uicontrol('Style','edit','BackgroundColor','white','Units','Normalized','Position',[.1 .1 .4 .1],'String','Enter your phone IP address here',...'Visible','on','Callback',@callbackfn);

Using the code you provided above:

IP_Adress_Phone=uicontrol('Style','edit','BackgroundColor','white',...
    'Units','Normalized','Position',[.1 .1 .4 .1],...
    'String','Enter your phone IP address here',...
    'Visible','on','Callback',@callbackfn);

In order to extract data, you need to define the callback. The callback's first parameter will be a reference to the IP Text Field itself. You can then extract the Text Field's "String" Property.

function callbackfn(hObj, e)
    ipAddr = hObj.String;
    disp(['ipAddr: ' ipAddr]);
end

Callback's Documentation for reference:
