You could try using java.robot. I used it in one our code tests for a line moving on an axis. It worked well, except for the fact that if the user happens to move the mouse it interfered with the test. But then if the user moves the mouse you wouldn't expect the cursor to still end up where you put it programmatically.

Try using uicontrol to set focus to the username text box.

If you are using GUIDE, then in the OpeningFcn just add the line

 uicontrol(handles.edit1);

where edit1 is the handle to the edit text box for the username.

If not using guide, then you should be able to do the same call with the handle to the text box. Something like

 figure;
 hUsername = uicontrol('Style','edit','Position',[2 30 12 2],'Units','characters');
 hPassword = uicontrol('Style','edit','Position',[2 26 12 2],'Units','characters');

 % set focus
 uicontrol(hUsername);

Tevfik - I'm not too clear on what you mean by when new barcode entry came, How can delete old barcode from edit1 box and enter new barcode? What is the barcode - the username, or is this something different?
