Hi,
I have a GUI (GUI2) and want to get the handle of another one (GUI1) which is already running behind the actuall GUI-Window. If I use GUI1handle = guidata(GUI1) I get the handle but the Window behind opens again. How can I solve this?

The accepted answer to this question does not work for versions R2017a and R2017b. The return value of both calls is a '0x0 empty GraphicsPlaceholder array', i.e., not a handle to the gui window.
How can I obtain a valid handle to a gui window in R2017a or R2017b?

The first call can only work if you actually set a tag to your figure/object.
The 2nd works without any problem for me (2017b).
You could aswell just store and pass the handle when you create your figure.
It might also be a good idea to open a new question - this one is 5 years old and probably does not receive too much attention nowadays.

Possibly
findobj(0, 'tag', 'GUI1')
or
findobj(0, 'type', 'figure')
and exclude from that the figure(s) associated with GUI2.

Both approaches work in HG2.
However, if you are using GUIDE then the handle visibility of your GUI might be set to 'callback'. If it is, then you will need to use findall() instead of findobj()

>> hGUI = findobj(0)
>> hGUI.ShowHiddenHandles = true
>> hGUI = findobj(0)
hGUI =
236×1 graphics array:
Root
Figure (figure1)
UIControl (text171)
UIControl (pb_input_data)
UIControl (pb_skizze_vor
... and a lot more.
>> hfig = hGUI(2);
>> hfig.delete;
This will delete the seemingly locked object.
