Hi,
Is there a way to set handles of another GUI? I have a main GUI which prompt a sub GUI. In the sub GUI,when a button is pressed and it will set the main GUI visible off.
set(handles.fig1,'Visible','off');
I place this code on the the button of my sub GUI. fig1 is the handles of my main GUI. However to code has error because the sub GUI doesnt know the handles fig1.

Set the Tag parameter for the main GUI's figure, and then in the sub-GUI
handles.fig1 = findobj(0,'Type','figure','Tag','TheTagYouSet');

Try
close('all')
now run your program again and see what comes up.
If it still shows multiple items in hgui1 then try
hgui1 = unique(findobj('Tag','gui1'))
If that still returns multiple entries, please show the output of
struct2cell(get(hgui1))
